My Girlfriend's Younger Sister Ch. 01
Sarah asks questions about me and her sister's sex life.
All persons engaged in sexual activity in this story, are over 18 years of age.

This was a real event that happened in 1969, when, bear in mind, there was no internet where anyone could readily obtain information like today. Only the descriptions have been embellished to make a more readable story. There is an element of cheating in the story, so if you don't agree with that, you don't have to read it, otherwise, enjoy.

Part One. The questions begin.

It was the time of mini-skirts, Austin Minis (I had one then), and just around the time the Beatles were breaking up, that at 20, I met and started going out with Jayne, who would eventually be my first wife. She was the same age as me, very slim, had long dark hair, as was the fashion, long legs, and wore the tiniest skirts you could imagine. She lived with her parents and had an elder brother and sister, both of whom had married and left home, and a younger sister Sarah, who was just 17 at the time, lived at home too and was in the final year of school.

I met Jayne in late spring at my school reunion dance, where she and her sister had been dragged by one of her friends who had been a former pupil at the same school as me. The three girls, the one I knew and the other two, were of course dancing together, around their handbags that they had placed on the floor - it's what they did then. When their friend left them to go and talk to another group, me and my mate plucked up the courage to shuffle over and join them, being the only two girls we could see that we hadn't been to school with.

They seemed happy for us to join them and having got their names, and introduced myself as Pete and my mate Dave, were soon chatting and asking the usual questions like 'what do you do', 'where do you live' etc. while we carried on dancing. We seemed to be getting on well, me with Jayne and Dave with her sister Sarah. As sisters, they didn't look alike at all. They were both about the same height, around five foot six or so, however, Sarah was a redhead, with curly hair, light skin and freckles, while Jayne was dark haired and very slim with only a slight indication of breasts. Sarah had more of a figure and so had a bit more shape to her, and from what I could see, nicely shaped, larger breasts. I was more a leg man in those days and Jayne more than made up for having not much 'up top' with her long slim legs, most of which were showing from under her small skirt. We stayed with them for the rest of the evening and at the end, it was natural then that we agreed to meet them as a foursome later in the week and go ten pin bowling at a local venue.

Jayne it turned out was training to be a nurse, and so worked varying shifts at the hospital, so we had arranged our date to coincide with her day off and an evening when her sister didn't have a lot of schoolwork to do.

It all went well, but we realised that going out as a regular foursome was difficult to arrange because of Jayne's shifts and Sarah's schoolwork, so that was the first and only time we did.

Time moved on and Jayne and I continued to date regularly. I didn't see much of Dave as most of my free time was now taken up visiting Jayne and taking her out. Apparently, Dave and Sarah's relationship didn't go so well and one night about 6 months later, Jayne told me they were no longer going out together. She said that Sarah had told her Dave thought she was a bit immature and had found someone a little older, so they had ended it.

I was often at Jayne's house for the evening as we couldn't afford to go out every time, so I did get to know Sarah a little better and we got on well. The three of us often sat on the wide sofa together in the evening watching TV and had chatted about a lot of things. I personally didn't think she was that immature, although she was a little school and study orientated, but that was to be expected as she was nearing her final exams. Nothing ever happened at this time, she was just Jayne's sister and was often around.

A few months later, it was Sarah's 18th birthday, and their parents invited the family round for a few drinks and a buffet, so there were quite a few people there.

We all milled around chatting, drinking and filling our plates from the buffet that her Mom had prepared, and it was a very convivial evening.

The other people were standing or siting chatting, but I found myself at the buffet with Sarah, both getting a second helping.

"Pete," she said, looking round to see where everyone else was, "can I ask you a question?"

"Of course," I replied, wondering why she had got me alone to ask.

"Well, you're a bloke, right?"

"Was last time I looked," I joked.

"Ha ha, funny, no, seriously, I need to ask you something."

"Ok sorry," I said, intrigued now.

"I meant, as a bloke I need your opinion," she said quietly, a slight blush creeping up her neck.

"Right, go on then."

She looked round again to make sure she wasn't being overheard. "If... if a girl offered it to you on a plate, would you accept?" she asked, concentrating on her plate of food.

This question threw me, for a moment, did she really mean to ask what I thought it meant, or had I misinterpreted it. I wasn't sure

"Ehmm, I'm not sure what you mean." I whispered, playing for time.

"Yes, you do," she said, her green eyes flashing at me, "don't procrastinate, I just want a truthful answer from a bloke I trust."

"Well," I started, "I suppose it would depend on who was offering and what the circumstances were."

"Yes, but would you be tempted?"

This was getting a little awkward with people not too far away.

"I'm not sure you should be asking me this, after all I am going out with your sister. I wouldn't want you to get the wrong idea," I replied.

"I am not going to say anything, and I don't think I can ask anyone else; I just want to know what you would think." she pressed.

I paused for a moment, "I guess I could be tempted, if it was someone like you for instance," I smirked.

She blushed even more, "Oh... okay, well thanks for being honest, I just wanted to know how blokes thought." she mumbled.

"What's this about," I asked.

"It's nothing," she said, "I was just thinking about something, it's not important," she finished, as she slowly moved away.

It clearly was important I thought, or why would she risk embarrassment asking me. I didn't know what had prompted the question, but I was secretly pleased that she trusted me enough to ask me and a little intrigued.

The rest of the evening passed pleasantly enough and eventually the visiting family members left and the rest went to bed, leaving Jayne and myself alone at last in the living room. We had messed about before when everyone was in bed, but we were too nervous about doing much now, as we had nearly been caught a couple of times before by her Mom. We had also gone 'all the way' a few times both on the sofa and in the back of my Mini, but it required a lot of manoeuvring in there, and it wasn't very comfortable squashed in the back. One afternoon we had actually managed to do it in her bed while her parents were at work and Sarah was at school, that was much more comfortable and safer.

This time though, we only went as far as kissing for a while and then she let me put my hand up under her top and fondle her small breasts until I had got her nipples hard. I then transferred my hand up under her short skirt and down into her knickers, slowly finger fucking her for a while as we kissed, until she said she was really tired, and I knew it was my cue to leave. On those evenings, I would drive home with blue balls and the smell of her on my fingers.

**************************************

The next time I went to see Jayne was a weekday, when she had been on an early shift, and theoretically finished at 4pm. We just intended to stay in for most of the evening or perhaps go to a local pub for an hour or so later, just to get a bit of privacy from the rest of the household.

I got there about 4:30pm, giving her a bit of time to freshen up a bit when she got home after her long day. Sarah answered the door which she did sometimes, and let me in. She was wearing a short, dark crop-top, that showed off her breasts and left a little of her stomach showing, along with a short, flared skirt and bare legs. She had obviously changed out of her school wear into something more casual. I couldn't help looking a little longer than perhaps I should have, but she was looking 'girl next door' attractive in that outfit.

"Sorry Pete," she said, "Jayne has just phoned, they need her to stay for another couple of hours, I couldn't get hold of you as you had already left home."

"Oh, that's a shame, I guess she will be more tired than normal," I replied, wondering if she would want to stay up late after such a long day.

"Maybe, but go have a seat in the living room, and I'll get you a drink, I was just about to make myself a cup of tea anyway."

"Thanks tea would be great."

I sat down at one end of the three-seater sofa and after a few minutes Sarah appeared carrying two mugs of tea and a few biscuits on a plate. I was slightly surprised that after she had put the cups down on the low table in front of the sofa, she came and sat right next to me on the centre seat. She turned very slightly towards me and was showing a lot of bare leg.

I made some conversation about her schoolwork and forthcoming exams, she in turn asked me about work and a few mundane things as we sipped our hot tea. It was all very normal, as I said, we got on well and it wasn't unusual to be chatting like this as friends, during the times I had waited for Jayne to get ready upstairs, on other occasions.

Then she said, "You know that question I asked when you were here for my Birthday last week?"

"Err.. yes , I remember."

"Did you really mean it, that you would be tempted if it was me?" she said, looking directly at me with those green eyes, a slight flush creeping up her neck.

"Well, it was a sort of joke, but..."

"You mean you don't find me attractive enough?" she butted in.

"No, emm... I mean yes," I felt I was digging a hole for myself, "what I meant was," I paused to try to get the next bit right, "that anyone would be thrilled if you offered, what you said."

Her fair skin was blushing deep red now, highlighting her freckles, "Well why wasn't your mate Dave then, when I gave him all the signals, he didn't seem to want to touch me and told me he thought I was too 'immature', and we finished after that."

"I don't know Sarah, perhaps he was being nice in a way, not taking advantage of you. You are intelligent, attractive, good company."

"Well he didn't make me feel all those things."

"Can I ask you... what made you decide to 'offer yourself on a plate' as you put it last week? I asked tentatively, "you don't have to answer if you don't want to, I was just curious," I added.

She didn't reply immediately, and I thought that perhaps I should change the subject and talk about something else. I was just about to ask her a more general question, but we both started to talk at the same time, so I stopped and asked her to go first.

"You won't be annoyed if I tell you?" she said, looking down into her tea mug.

"We're friends I hope, so I am sure you won't annoy me whatever you want to say," I replied, softly.

She took a few breaths, "This is a bit embarrassing, but when you and my sister stay up late down here, my bedroom is directly above and sometimes you make a bit of noise and I can hear you."

"Hear us?" I said, getting a bit embarrassed myself now.

"Yea, you know, doing things."

"Oh," I said, I am sorry, I had no idea, we try to be incredibly quiet. But what's that got to do with the other thing with Dave?"

"It just sounded as though you were both enjoying it?"

"Well yes I suppose we do."

"So, I sort of wondered what it would be like, if you see what I mean."

"You've never, you know, done anything then?" I asked, not knowing if she would discuss it.

"Not much, no, I have not had much time for boyfriends with all the schoolwork, and anyway the boys of my age just want to boast to their friends about how far they have got with a girl, and I didn't want to be a school statistic," she smiled sadly.

"No, I can understand that."

There was silence again, but I had the feeling the conversation wasn't quite over.

"Can I ask you something else," she said, "sort of personal?"

"You can always ask," I replied, "but it depends on how personal it is as to whether I will give you an answer."

"Yea, that's fair enough."

"So, what was it?" I asked hesitantly, not knowing where this might be going.

"It's just, I'm not sure how to say it," she started a bit reticent, so I didn't know what was coming.

"Just say it Sarah," I encouraged her.

"Ok, well, I was just sort of curious if you and my sister had done it, you know, gone all the way?"

I wasn't sure I wanted to discuss this with Sarah, but it was kind of sexy for her to be asking such an intimate question.

"Hmm, I'm not sure I should be talking about it with you, I doubt Jayne would approve." I said.

"She won't know will she unless you tell her, I certainly won't." she replied quickly, her face still red.

I wasn't sure why she wanted to know, I could always just pretend we hadn't, but I thought that it wasn't that much of a big deal if she knew, as long as she didn't tell her sister we had been having this conversation.

"You promise to keep this just to yourself?" I asked.

"Of course, it's just between you and me."

"Then yes we have." I said, finally answering her question.

"How many times?"

"Oh just a few."

"Wow," she said, "where did you do it?"

"Do you need to know that?" I asked.

"I suppose not, but, was it like here, in the house?" she persisted.

"A few of times," I replied, giving in, "a couple of times where you're sitting." I added, thinking that would maybe stop the questions.

"Really," she said, touching the cushion and opening her eyes a bit wider, "is that what I might have heard?"

"Perhaps, Emm, didn't you think it was a bit gross, hearing us?"

"No, no, it was actually a bit exciting, but I didn't know what you were actually doing then. Wow, you were doing it right here."

I didn't know why she found that such a revelation or of such interest, although from what she had said earlier, I knew she didn't have much experience, and I could only think she was looking for some answers to things she had only imagined up to now.

"And once in Jayne's bed." I added, for good measure.

"There too...ohhh," she almost groaned.

Her skin was still flushed, and she seemed absorbed in the subject.

The intimate nature of her questions with her sitting so close to me had woken up my cock, which I felt beginning to stir in my jeans. It didn't help when she asked...

"Was it on here, the first time with Jayne?"

"Yea, it was."

"What was it like, the first time with her, I mean?" she continued.

"Sarah, like I said before, I really don't think I should be telling you any of this, if your sister ever found out we had been talking about it, there would be big trouble for both of us."

"Yes, and I told you, no, promised you, that she won't find out from me," she stated firmly. "As I got turned down, I haven't yet got to try it, I just wondered what it is like and how you, you know 'do it'?"

"I'm not sure as a male I can really tell you what it actually 'feels like' for a woman," I said, "what sort of things do you want to know?"

"Well not really that, but just how it went, like, for instance, did you both take off all your clothes right here, where we are sitting? Did you lie down or what?"

I noticed she squeezed her thighs together and then relaxed them, as she asked the last question.

"No, it would have been too risky to be naked, anyone, even you for instance, might have come downstairs for something." I said, remembering how we had listened hard for any slight noise.

"How...how did you do it then?" she pushed, her breath coming a little faster as she spoke.

"You don't need to lie down, there are other ways," I said.

"Yea, I know the mechanics," she said, "and I know it can be messy, but how did you do it, I didn't see anything on the cushion?"

"Do you really want all that detail?" I asked.

"I imagined how it might happen, but I'd like to know more."

"In answer to your question, we were careful, we left her skirt on."

"How does that help?"

I wondered how much detail she wanted. She was pushing further into intimate details that I never thought I would discuss with Jayne's sister, or anyone else for that matter, but I could see it had excited her. The memory of fucking Jayne where we were siting had turned me on too, and although I knew we couldn't and shouldn't do anything, my cock was now almost fully hard. The excitement of the taboo nature of our conversation was overriding the thought process that had told me I had said enough. Anyway, my excited brain rationalised that, she was an adult now, and it was an adult conversation.

"I knelt on the floor, with her in front of me." I said, in answer to her question.

"Like just there," she said, indicating the carpet in front of us.

"Yea, we just pushed the coffee table back a bit."

"Ohh," she sort of gasped. "Show me."

"What?" I asked, incredulously.

"Come on, show me how, I don't mean for real, we both have our clothes on, so it's not a big deal," she cajoled.

"I don't know Sarah, that might be a bit too weird and too far."

"I just want a real image to go with what I heard, it won't hurt anything and it's just between us...right?"

Was I in my right mind? I was actually thinking about showing her. The sensible thoughts in my head were getting quieter and the thought of getting into a potential fucking position with Sarah, had got my heart beating a little faster because of the naughtiness, but after all, it was only a demonstration, and we were fully dressed. It wasn't as if I was seducing her, I convinced myself.

"You're sure you want to do this?" I asked, giving her a chance to say she was joking.

"Yea, it sounds fun," her eyes sparkled, "what do I have to do?"

"I still think this is weird, but if you're sure."

I slid down onto the floor on my knees in front of her. I knew that to show her properly, she would have to open her legs to let me between them, I wondered if that would be the point at which she would change her mind.

"Now you need to lie back and slide your bottom right to the edge of the cushion, but keep you skirt underneath you, that protects the cushion" I explained.

"Like this," she said doing as I had said.

I edged forwards until my front was touching her knees.

"Now you need to open your knees so I can be between them," I said, "but if you have the idea now, you don't have to and we can stop."

"No, let's do it properly," she replied breathlessly, her face still very red.

Her legs slowly opened, the back of her skirt just covering the cushion, the front stretching further up her legs the wider she opened them. Her small white knickers came into view and even at this point, I could see the front was damp and had become slightly transparent, giving me a hint of dark red pubic hair underneath.

I shuffled forwards, aware that there was now a big bulge in the front of my jeans where my very erect cock was pressing forwards. I put my hands just on her hips and slid her a little more towards me until my bulge contacted the front of her knickers. I saw her eyes had a bit of a glazed look and she seemed to be trembling slightly.

"There," I said, pushing hard against her mound, "so does this answer your question?"

"Nearly," she whispered sexily, "show me how you moved."

"You want me to move?"
"Yea, like you do with Jayne."

I realised it had gone beyond just chatting about sex and I was about to dry hump Jayne's younger sister, but it was very sexy, and my lower brain reasoned it wasn't really sex.

I moved experimentally against her, my hard cock in my jeans pushing against her mound through her underwear. After a few strokes, she got the idea and started to meet my thrusts. Even though we were fully clothed, there was no doubt that this was far beyond where we should have gone, but I didn't stop. She was really getting into it and starting to moan, her teeth over her bottom lip and her eyes half closed. I could feel her thighs each side of my hips, almost the same as when I fucked Jayne for real here, and now I was dry humping her sister.

As we got into a rhythm, without thinking, I moved my hands up and cupped both her breasts, her eyes flew open and I realised what I had done, and quickly removed them.

"Sorry," I said, "I forgot what I was doing."

"It's ok" she mumbled, "I liked that, put them back."

"You want me to ...fondle you?"

"If it's what you normally do, yes." she whispered.

I had wondered from afar what Sarah's breasts might be like compared to her sister's small ones, and now she was inviting me to find out. So tentatively I replaced my hands, one on each breast, and moved them around, feeling her bra underneath and a hint of nipple. The more I cupped and moved my palm over them, the more prominently I could feel each nipple responding.

I too was breathing hard now, and my heart beating fast, as I continued to slide the erection in my jeans against her knicker clad pussy. This was so taboo, but the more exciting because of that and I could tell Sarah thought so too, by the noises she was making. I was glad no one else was in the house.

"Do you want to touch them?" she asked, through her heavy breathing.

"Well I already am," I said.

"No, underneath, you can, if you want."

So far it had really all been simulation and fully dressed, now she was tempting me to feel her bare breasts. I didn't have to think long to know I was a weak-willed man.

I slide my hands up under her crop-top onto her bra and stroked her breasts with only that between my hands and her bare flesh. Her nipples were rock hard and easy to pinch between my fingers. That elicited more groans and I felt her pressing her damp mound harder towards me. Her bra wasn't that tight and automatically I pushed the bottom of the cup up, freeing those warm globes right into my waiting hands.

They were very firm and although I couldn't actually see, I could feel the hard nipples sat right on the top, as they should be on an eighteen-year-old girl. Now that I had them in my hands, I was able to feel them and stroke them without any obstruction. I traced the areola with my fingertips, feeling little bumps, like small goose bumps, all around the nipple. Sarah was humping me for all she was worth, her hands gripping the cushion each side of her and breathing like she had just run a few miles. With all caution out of the window now, I was just going to move my hands down towards her pussy, when her legs started shaking. She gave a very loud groan, that I am sure could have been heard outside, and then shuddered and trembled her way thought her climax.

"Oh Jesus, Pete, what's happening," she stuttered, shakily, as the first part of her orgasm ripped through from her depths.

Her mouth was open in what seemed like shock, and her eyes were pointing everywhere except towards the front. I gently massaged her nipples and held my crutch hard against hers as she went through multiple contractions and twitches. They gradually diminished as her climax passed and her eyes regained some sort of focus.

"Ohhh, I didn't expect that," she said quietly, "I just thought it would be like when I make it happen myself, but that was far more intense. I wonder if that's what everyone feels," she mused, almost to herself.

"It looks like you enjoyed it," I smiled down at her, "even though I think I let it go too far. But did it answer your question?"

She sat up a little, so that although I was still between her legs, we lost the intimate areas contact we had shared.

"Did it,,,wow,." she said. "if that's what it does to me like that ... I wonder how much better it can get. Can you answer another question?"

"I guess we have come this far."

"I could feel you through your jeans, you know, hard against me, did I make it get hard just talking to you?"

It was my turn to be a little bashful, "Well yes, as I said you are attractive, don't ever think you're not."

"And it is still... hard."

"Err yes."

"Can I see?"

"What you mean take it out, here?"

"Yes, it won't hurt for me to just see, will it? There's no one here and you know I am not going to say anything to anyone." she pleaded.

"I don't know, maybe we have gone far enough," I said, perhaps a little unconvincingly, as the thought of her seeing and maybe handling my cock did have its appeal, as I hadn't come yet.

"Go on, just for a minute," she wheedled.

"Hmm, ok, but you can't talk about this ever."

"No, of course." she said, definitively.

I stood up in front of her, still between her legs and unbuttoned and unzipped my jeans, pushing them down to mid-thigh. I could see her eyes glued to the bulge in my underwear and her tongue wetting her lips out of nervousness. Taking the waistband, I lifted it over my solid, erect cock, and lowered them too, putting my cock right in front of her. I only have an average six and a bit inch cock, but it has a fair girth, so I am not ashamed of it.

I heard her intake of breath, "Wow, I didn't realise, it would look that big close up," she said, "does Jayne take all of that inside her?" she asked, almost unbelievingly.

"Yes, it's meant to fit," I grinned.

"Can I just touch it," she asked, moving her hand outwards.

I just let it happen. She gently touched the shaft, slightly surprised when it jumped up a little. Then she put her hand round it and slid it down, pulling the foreskin down to expose the head. It was already wet, but a large drop of clear pre-cum oozed out of the slit at the end.

"Oh, that's not sperm is it," she said.

"No, it's clear so its pre-cum, it's like a lubricant, slightly slippery, they probably don't tell you that in biology class," I replied, enjoying the feel of her hand, as she slowly wanked me with her hand motion.

She used her other hand and ran her finger over the slit, rubbing the clear liquid with it.

"Oh yes, it is, very slippery," she said, fascinated.

I was starting to enjoy her ministrations, watching her face, and thinking maybe she might give me a full handjob, when I suddenly heard the unmistakable noise of the front garden gate latch, open and close.

"Oh Shit, Jayne's home, quick go upstairs," I said, as I quickly pulled my underwear and jeans up.

I said she was intelligent, she picked up the extra tea mug and darted out of the room like a scared rabbit, rushing up the stairs a few moments before the front door opened.

Jayne closed the outside door, hung her coat up in the hall, and came into the room.

"Sorry I'm so late," she said, "I hope Sarah has been looking after you, and you haven't been too bored waiting,"

"No, it's ok, she made me tea," I replied, trying to control my breathing, "and then she went upstairs, I assume she has work to do," hoping my face wasn't too red, and also hoping Jayne was in the mood for something later, because I was now...

Sarah wants to know more...
All persons engaged in sexual activity in this story, are over 18 years of age.

This was based on a real event that happened in 1969 that is burned into my memory, when, bear in mind, there was no internet where anyone could readily obtain information like today. Only the descriptions have been embellished to make a more readable story. There is an element of cheating in the story, so if you don't agree with that, you don't have to read it, otherwise, enjoy.

Part Two.

A few days later, I called Jayne on the phone and asked her if she would like to go out on Saturday evening for a meal or something. Unfortunately, she said she had an evening shift at the hospital where she was training to be a nurse, but we could maybe go into town during the day. She wanted to buy a few clothes, and if I didn't mind shopping with her, we could spend part of the day together, but she had to be at the hospital by 5pm.

It was a bit of a disappointment, but I knew she felt that nursing was her vocation, so for the moment, she had to work these unsociable hours now and then. I wasn't too enthusiastic about trailing round female clothes shops, but if it meant I could spend that time with her, then I was sure I could put up with it.

I arranged to drive over and pick her up from her home in my Mini car, at about 11am, giving us plenty of time to maybe have a bite to eat in town, and get her back in time for her to go to work.

**********************************

When I arrived and she let me into the house, she was almost ready to go. I thought I had better say hello to her mom and dad, and being Saturday, they would usually be home.

"I was just going to say hello to your mom and dad before we go," I said, when we were in the sitting room, "but they don't seem to be here."

"Ah no, they're not here, they have gone over to see my brother. He is moving house today, and as you know they have just had a baby, so they have gone to babysit while the move takes place. Actually, I think they just wanted to nose around the new house and offering to look after the baby was just an excuse."

"Just for the day?"

"No, they are staying over, but they will be back tomorrow." she informed me.

"Ohh, well what about you and Sarah?"

"What about us? We are old enough to look after the house for one night on our own, aren't we?"

"Yes, sorry, I wasn't thinking. It's ok," I said, feeling a bit foolish, of course, they were both adults, they didn't need their parents to be there all the time, I didn't know why I had said that. "So, shall we go?"

"JAYNE," I heard shouted from upstairs, "did I hear you say you are going into town?"

"Yes," she shouted back.

There were rapid footsteps descending the stairs and Sarah came into view.

"Is there any chance I could get a lift with you, I said I would meet my friend there to shop for a few things, it would save me the bus fare, and waiting for it?" she asked.

Jayne looked at me, "You had better ask Pete, it's his car."

"Pete?" she said, putting on a 'lost child' expression.

"Errr...Of course, no problem," I said.

Well, I could hardly say no, as she was Jayne's sister, and after what we had chatted about and done last week, it seemed best to stay in her good books. It wasn't as if Jayne and I were going somewhere to be private anyway.

"You are going now though?" she asked.

"Yes, why?"

"I am not meeting Jen until 2pm, maybe it's a bit too early now," she said, a little downcast.

I looked at Jayne, who gave a slight shrug to her shoulders in a 'it's up to you' sort of gesture.

I thought quickly, and wanting to be supportive to Sarah, but also hoping to gain a few 'points' with Jayne too, "How about you get ready and we go now, then we can get something to eat in town, I'll treat you both, then you can meet your friend, while Jayne and I go and shop for the things she wants. How does that sound?"

"That's brilliant Pete, thank you," Sarah said, a big smile breaking out on her face, then giving me kiss on the cheek. She sprinted back up the stairs to get ready.

Jayne looked at me and rolled her eyes.

"What?" I asked.

"You know she just manipulated you, don't you?" she said, half smiling now, "but thank you for being kind." She kissed me too, but on the lips this time.

While we waited for Sarah to get ready, we took the opportunity to sit on the sofa and kiss a little more. We were sitting right where I had sat with Sarah that time, and as the memory came back of secretly dry humping her sister, I gently moved my hand up and massaged Jaynes breasts over her clothes.

"We can't go too far; she'll be down soon. I don't want her to catch us," she whispered.

"Yes, I know," I whispered back, thinking that it was just what Sarah would like to see, but I couldn't tell Jayne that.

I tried to move my hand to her leg and up her short skirt, but she stopped me, "No, that's going too far now," she admonished me. So, I had to settle for kissing a little more and feeling her breasts.

We heard Sarah moving about upstairs, then her feet on the stairs again. Jayne quickly pulled apart and stood up just as her sister opened the door.

Sarah had dressed in tight fitting jeans and a loose woollen pullover, then thrown a long jacket over the top, as it wasn't too warm outside.

"Ok, I'm ready," Sarah said, looking from one of our faces to the other, "getting warm in here is it," she grinned.

"Enough of that if you want a lift," Jayne retorted.

Sisters huh!

**************************************

The trip into 'town', actually a city, but we called it 'town', was uneventful. Sarah was a bit cramped in the back, but it was a Mini and she didn't complain. We had BBC Radio 1 on the car radio, and the two girls sang along to some of the pop music they were playing, while I concentrated on the driving. It was a good atmosphere.

Parking wasn't too much of a problem in those days and being a small car, I soon found a parking space not too far from the main shopping streets.

We had a short walk round looking for somewhere to eat and settled on a Wimpy Bar. I think we all had the speciality burger and chips (french fries) and soft drinks, as they didn't sell alcohol. It took a while to get our meal, and we ate it at a leisurely pace, chatting about this and that, so by the time I had paid the bill, Sarah only had about fifteen minutes before she was due to meet her friend.

"Right," I said, as we were leaving, "if you want a lift back home Sarah, meet us back here at 4pm as I have to make sure Jayne is back to go to work on time."

"Oh, that would be great, thank you, I'll make sure I'm here," she replied, gratefully, then kissing me on the cheek for the second time today, she went her own way.

As we walked towards the shops, arm in arm, "She seems to like you," Jayne commented, an inscrutable look on her face.

"Well, what's not to like, free transport and food, can't be bad, can it?"

"No, I meant, she does seem to genuinely like you, she hasn't been that way with any other guys I have been out with. What's your secret?"

"Secret?"

"Yes, what have you done that makes her like you more than the others?

I think I was blushing, but we were walking into the wind and I don't think she noticed, "I guess I just treat her like the adult she is, rather than your younger sister."

"In what way," she asked, checking for traffic as we crossed the road.

"Emm, well, just talking about different stuff that interests her and generally listening to her opinions and what she has to say," I replied, hoping she wasn't going to ask what we talked about.

"That's good, I think she misses our brother being at home, she used to talk to him all time, it will do her good to be able to talk to you." she said, squeezing my arm.

"Where are we going first," I asked, trying to steer the conversation away from her sister, I doubt she would be so pleased if she knew the things Sarah wanted to talk about.

I can't remember how many shops we went into, and the numerous times I stood near the changing areas with a few other bored guys.

As we stood there, (they never provide seats for the guys do they) a parade of girls went in and out with clothes over their arms. It was obvious that I wasn't the only one taking surreptitious glances, to see if the girls closed the curtains properly, while appearing to look anywhere else but at the curtains. Jayne tried on various skirts, jeans, tops, you name it, she tried it on, and popped out every now and then to ask if I liked whatever she had changed into.

Finally, she said she had finished, and so with a few bags carried between us, we made our back to the Wimpey Bar to meet Sarah.

She was on-time, and when she spotted us, started to walk towards us. I noticed that she too had a couple of bags, so I guessed she had had a successful shopping trip too.

The ride back was similar to when I drove there, and both sisters seem to be in a good mood. Obviously 'shopping' produced good endorphins I thought.

We got back to the house in good time and while Jayne went upstairs to change into her uniform, Sarah made us all mugs of tea and a few sandwiches and brought them through to the sitting room.

"Did you get what you wanted?" I asked conversationally.

"Yes, I got a few bargains, and thanks again for lunch and the lifts, it makes it so much easier than struggling on a bus."

"That's ok, glad to have helped. I remember what it was like before I got that little car,"

"I hope to get one, one day," she said, "but I'll have to learn to drive first."

"Yea, that's a good idea, I knew you were smart," I joked, laughing, and got a playful slap on the arm for it.

"Are you rewarding the man who has just bought you lunch with a smack?" Jayne said, as she came into the room at that moment.

"Naw, we were just having a bit of a laugh about whether your smart sister should get a car first or learn to drive first," I explained.

"Oh yes, if only," Jayne smiled, drinking her hot tea quickly. "Now, I need to get going, I don't like to arrive on the ward late."

"I'll take you in the car," I said, as I am here.

"You haven't touched your tea or sandwich yet, it's a shame to leave it."

"Well if its ok, I'll drop you off at the hospital, it will only take a few minutes, and come back for it, then I'll wander off home."

"Yea, sure, Sarah will still be here - probably see you tomorrow Sarah, as I won't be home until very late, don't forget to lock the doors before you go to bed." she added.

"I know, I know. You would think I was twelve, not eighteen," Sarah mumbled to herself.

"We had better go, or I will be late," Jayne said, smiling.

****************************************

The hospital where Jayne worked was about a fifteen-minute walk, but only a couple of minutes in the car.

I dropped her off with a few kisses, then I made my way back to her house.

Sarah opened the door at the first knock, so I assumed she had been looking out for the car.

"Come back into the sitting room, the tea and food are where you left them," she said.

"Oh great, I hope the tea is still warm."

"I can always make some more if you want," she answered, as we sat back down onto the sofa in the sitting room.

The TV was on, so I sort of focussed on that, as I munched my way through a very nice ham sandwich and yes, the tea was still warm enough. Sarah was sitting beside me also just casually looking at the TV.

"Nice sandwich, thanks," I said, as I finished the last crumbs and started on the tea.

"It's the least I could do after you two letting me join you."

"It was fun singing along in the car, even if you are both tone deaf," I quipped, and got another friendly slap on the arm. "Anyway, you never said what bargains you bought when you were transported in style to the shops?"

"Just a few clothes. I am trying to build up my wardrobe a bit at a time now that I am finishing school, I will need different sorts of clothes."

"Yes, I suppose so," I replied, not that I knew what she might need.

She thought for a minute, "Would you like to see? You can tell me if they suit me. My friend Jen said they did, but a guy may have a different view."

"Err... yes, emmm, sure if you want to," I said, not sure what sort of clothes she had bought, and wondered if it was wise, or whether I should really be leaving to go home as Jayne would expect me to.

"Ok, stay here, I will be back in a minute," Sarah said, getting up and disappearing out and up to her bedroom.

I sat back and watched a bit of TV, I think it was the early evening News, I wasn't paying much attention, it was just something to watch.

She had previously told me that her bedroom was over the living room, which is how she had embarrassed me, by telling me she had heard me and Jayne having a bit of late night fun, and I could hear her moving around up there.

After four or five minutes, I heard her coming back down the stairs.

"Here I am," she said, a bit shyly, as she entered and walked to stand in front of the TV.

From my sitting position, I was looking slightly up at her. I ran my eyes up and down her body. She was now wearing a tight white top, with a few sparkles, in a stretchy sort of fabric that clung to her breasts. I tried not to stare, but it looked as if she wasn't wearing a bra, as I couldn't see any lines under it, and her nipples were making small tents in the fabric.

I expected her to be wearing a miniscule skirt of some sort, but that wasn't the case. She was wearing a red skirt, that snugly fitted her bottom and ended a couple of inches above her knee, but from high up on the thigh, the skirt had lots of fabric that was made into lots of pleats. I don't know what it was called, but it was vaguely reminiscent of the 'Flapper' fashion of the 20s. The difference being that it was much shorter than in that era.

She was blushing with my scrutiny, so I let her stew a little, while I continued to run my eyes over her.

"Wow, Pete, anyone would think I was naked the way you're looking at me," she giggled, "what do you think?"

"I think," I started slowly, "that, you have a great sense of fashion." I said.

"A 'great sense of fashion', is that it?" she said, mimicking me.

"Well ummm... no, not just that, very sophisticated and even sexy," I said, wondering if that was what she wanted to portray. "I am a bit surprised though that you have chosen a longer skirt than normal," I added.

"Ah, well it has a surprise," she said, coquettishly and blushing a little more.

"A surprise, what do you mean?"

"I'll show you. So, when I go to a dance, and swirl round...."

She did one pirouette.

"Ohhh." As she spun round, the pleated part of her skirt floated outwards, revealing most of her legs, and the tiniest, teasing, flash of her black knickers. It looked as though it was inadvertent, but it was carefully orchestrated for maximum tease factor. It was one of the sexiest things and bound to make the guys keep looking at her to see if there would be more.

"Judging by the fact that your mouth is still open Pete, I guess you liked that?" she grinned.

I shut my mouth and cleared my throat, "I wasn't expecting that," I said, my voice a bit shaky.

"If I turn a bit faster..."

She did, and I saw a lot more of her black knickers and her shapely thighs, right up to her bottom.

"Wow, Sarah," I said, that is definitely sexy, but I am not sure you should do that in public, everyone will see your...umm underwear." I said.

She laughed, "Please don't start talking like my dad," she said, still grinning. "Anyway, people see me in my bikini when I am on holiday, and in my swimming costume when I go to the local swimming baths, there isn't much difference."

"Except its underwear," I retorted.

"Yes, but I bought these specially to go under it, they are featureless, like swimwear, see?" With this, she raised the front of her skirt up to her waist giving me a stunning view of her long legs and knickers, tightly clinging to her.

If it was designed to start getting me turned on, it worked. I felt my cock stirring and a change in my adrenaline level, making my heart beat just that little bit faster.

She walked over towards me; I was sure the tenting where her nipples were had gotten bigger. "So, you like it then?"

"Yes, I do, very... modern, and as I said, sexy." I felt my face getting hot.

"I'd better go change," she said, "don't want it creased or dirty before I have had a chance to show it off."

She went back upstairs, leaving me to think about what I had just seen. I think my cock was having thoughts of its own, as by now it was almost erect in my jeans. I adjusted it a little, so it was lying a bit more comfortably, and tried to stop thinking about what I had just been shown.

She was back in a few minutes, and sat back down beside me, but this time she had on a long thick bath robe (dressing gown as it was called then), tied tightly at the waist.

"Didn't think it was worth getting fully dressed again," she explained, "I will probably be sitting here in front of the TV until I go to bed."

I didn't say anything, but it was a bit disconcerting, and I was glad no one else was due home, as it might look a bit odd for her to be found dressed like that with only me there.

We both remained still, the TV quietly droning in the background, but she was picking at tiny fluffy bits on her robe and I had a kind of feeling that she wanted to say something, and was building up for it.

"Pete," she said quietly, "can I ask you something else?"

"You know you can," I said, "after last time," I raised one eyebrow at her.

She gave a small, embarrassed smile and continued picking.

"It was about that sort of thing," she was blushing again.

"Don't you discuss these things with your friends or Jayne?" I asked, gently.

"Oh no, definitely not with Jayne, she still thinks I am too young, just because I am not at work yet like her."

"Oh, I see, but what about people you mix with at school, your friends?"

"That's the problem, you see, if I ask any of them, they will know then that I don't know a lot of stuff and probably make fun of me. Maybe they don't either, but they all pretend they do, so that everyone thinks they are mature and have done things that they haven't really. Does that make sense to you?"

"Yea, I think I get it."

"You are sort of 'remote' from all that, so you're probably the only one I can ask. I don't want to be ignorant about it all when I meet someone I want to do things with, and I am sure you won't laugh at my lack of knowledge."

"No, I wouldn't laugh at you Sarah, but as I said before, if Jayne or anyone found out we were talking about," I paused, "sex," I paused again, "as I said, it would be extremely awkward."

She was quiet for a moment. She put one hand on my leg, "I would never say anything Pete, I'll just keep all we talk about in my head, it's just between us, so don't worry, you're just being a good friend." She removed the hand.

I wasn't sure what I was letting myself in for, or the things she wanted to know, but as usual, the secretive nature of talking about this with her was a turn on, and my lower brain was persuading me again that it wouldn't hurt anyone.

"So, what do you want to talk about this time?" I said, quietly.

"Can I ask about you and Jayne, you know, the last time you were here?"

"You mean when you were 'asking questions' last time and she came home?"

"Yea," her face got redder, probably remembering what we did and her scrabble to get upstairs.

"Go on then."

"Even now it's a bit embarrassing to ask, but when I left 'quickly', when Jayne came home suddenly," she cleared her throat, "you were, I mean, your penis was hard, because of me, right?" she finally got out. "Did you use it on Jayne later?" I wondered.
I almost laughed at how naively she put it, but I knew I shouldn't and couldn't, "Yea, I did," I replied, more seriously than I felt, "were you trying to listen again?"

She blushed crimson now.

"To be honest, I was imagining what you were doing down here, and I did want to hear if you were doing anything. Especially so after I had just started to touch you, and I wondered, when you did it with her, were you thinking of her all the time, or did you think of me touching you?" she almost squirmed a bit at her own question.

"Sarah, I'm not sure how or whether to answer that, I mean, you know what we did was going a bit far, but I don't deny it was exciting, for both of us I think?"

"Yea, it was, that's why I wanted to know if I had affected you, when you did it with Jayne? You didn't answer the question."

I wasn't sure what was in her mind, and being truthful, I had for the first time thought about her younger sister, as I had fucked Jayne that night. It was inevitable that dry humping her sister and the 'almost' hand job that was aborted, had crept into my thoughts as I fucked Jayne hard on the same settee.

"It did a bit," I answered, "but I was only showing you something, and we got carried away."

"I know, but what we did almost felt like it was real, umm 'sex', feeling you against me like that. So, did you both do it for real, as you showed me, right here?" she persisted, once again noticing that she was moving her legs about under her robe. The talk was starting to get her aroused it seems.

"Well sort of," I hedged.

"Only sort of?" she looked confused.

"Jayne was tired, so she ended up laying down here on the sofa."

"And what, you were lying with her?"

"Yea, pretty much like that."

"Ohhhh." she said, more of an involuntary sound coming from what she was imagining.

I could almost see the thought process as she was picturing us on the sofa. She was getting into the detail now, but it was still a turn on seeing her eager red face, and knowing she was feeling the same naughty pleasure at discussing it and wanted to hear more.

"Did you have to sort of...clean up, doing it like that" she asked, tentatively looking at the cushions.

"No, this time we used a Durex," I said.

"Ohhh", again.

"You know it's a 'johnny', 'french letter'. or.."

"Yes, I know what one is," she interrupted, "so even though my sister is on birth control, cos I have seen her pills, you still use one?"

"Sometimes, yes, either just to be safe at certain times, or not to make a mess."

This seemed like a revelation to her.

"Ummm, I never thought about it that way, not that I have ever used one of course, or even seen one."

"Never seen one?" I said, without thinking.

"No, why would I," she paused, "I have wondered what they are actually like. Is there any chance you have one now...I mean with you? Can I see it?"

"I do, but there is nothing to see really, because its sealed."

"Let me see, ...please?" she said, putting her hand on my leg again.

I didn't see the harm in showing her, so I pulled out my wallet and slipped the small, oblong, foil packet out of one of the pockets.

"That's all it is," I said, holding it out to her.

She took it and fingered it, feeling the oval ridge of the latex ring through the foil. "There doesn't seem much to it," she said, "how do you get it on from this packet?"

"It's rolled up, and you just unroll it."

"What, like a rubber glove, you hold it and slip it into it?"

"No, no, you have to unroll it carefully down, from how it is in the packet." I tried to explain.

"Do you do it before you start or what," she asked, fascinated by idea of it.

"Just before," I said.

"Just before what?"

We were both blushing at how intimate the talk had got.

"Just before you actually, umm, join together," I said tactfully.

She was nervously fingering the foil packet, rotating it in her fingers.

"You mean just before you put it inside her?"

"Yes," I said, "exactly."

"Hmmm, now that we've come this far, could you show me?"

I thought for a moment, "If you really want to know how it works, I suppose we could open it and roll it down my finger. You can only use it once, then it has to be discarded, because it's not that strong, so wouldn't be safe, and anyway, it would be difficult to roll up again."

"The other night, you let me see and touch you for a moment, couldn't we do it for real, put it on you I mean. It's not going much further is it, I'd love to see how it fits, at least I'll know then," she said, persuasively, "you will have taught me how to use one, our secret."

My first reaction, which should have been my only one, was to say no, let her down gently and make my way home. However, she was right, my hard cock reasoned, it wasn't much more than we had previously done. She had already promised never to say anything. I was aroused again from us talking candidly about sex, she was in her bathrobe - and I didn't know if she had anything on underneath - and me with a hard cock making itself known in my jeans. It was too much of a temptation, so I listened to my cock.

"Are you sure you want to go this extra step Sarah; I am a bit nervous after almost being caught the last time."

"I am sure it will be ok," she said, "no one is coming back for ages."

"And you don't expect anyone else to visit?"

"No, I'm sure."

"It does feel a bit weird taking my clothes of in front of my girlfriend's sister," I said, giving every opportunity for Sarah to call it off.

She hesitated for a moment, "Can I do it," she said, shyly, "undress you I mean, I've never undressed anyone before, except myself of course," she giggled, nervously.

The time to not go further had come and gone I thought. Being here with Sarah, Jayne's younger sister and letting her take off my clothes, wasn't something I had anticipated when I started going out with Jayne some months ago.

My arousal and excitement were showing prominently in the front of my jeans by now. I could see in her eyes, and her flushed face, that she had seen it, and she too was very turned on by what we were talking about and possibly doing.

"If you really want to, and you're sure no one might come and check up on you?" I said, anticipating feeling her hands on me.

She nodded.

I stood up and moved in front of her, the bulge in my jeans at her eye level.

Her hands trembled slightly as she reached out and clumsily undid the button on my waistband.

"It is more difficult doing this to someone else," she said, grimacing, "it's all the wrong way round."

"I suppose it is," I said, looking down at her robe as it opened a little at the top when she bent forwards. I couldn't see much, just the slight valley where her breasts began.

She was tugging my zip down now and having to use both hands, one on the zip and the other to hold it straight.

I slipped my shoes off as she pulled my jeans past my hips and pushed them down to the floor, where I was able to step out of them. That movement made the robe open a little more.

Without the restraint of my jeans, my cock was pushing my underwear outwards.

She looked up at me as if asking permission, so I gave a small nod and carefully she pulled my waistband out and down, exposing my cock. She finished by pushing my underwear down to join my jeans, puddled on the floor.

Now I was standing in front of her, bare from the waist down, my cock seeping precum from the anticipation.

She reached out and touched the slippery liquid and rubbed it between her thumb and forefinger.

"Ummm it's doing this, like it did before," she said, staring at it on her fingers. "does it always?"

"Pretty much, especially if someone attractive like you is around," I said. grinning.

"I am sure you're just saying that," she countered.

"No, you are," I said, sincerely.

As she almost had my cock in her hand, I wondered if I could get her to go a bit further, so plucking up courage I asked, "I have been wondering what you have on under that robe, would you be willing to let me see?"

She took hold of my cock and slowly stroked it, as she had the other time, and I could see she was thinking about what I had asked.

"I don't have much on," she said, quietly,

"You could just open your robe," I pressed her.

"Well if you would really like to see, I suppose it's only fair."

She took her hands off my cock, and slowly undid the tied-off belt, then opened each side of the robe so that she was uncovered. She didn't look up at me.

I could now see that she definitely wasn't wearing a bra. Her pert round breasts, bigger than her sister's, were now in view. Nicely shaped, round orbs, each one topped with a darker circle and in the middle of that a plump, erect, dark nipple.

I looked further down and could see she still had those same black knickers on that she had showed me earlier.

"Wow, Sarah," I almost gasped, "you are more than attractive, such a sexy body you have. I am really surprised no one has snapped you up yet."

She was blushing again which brought out her adorable freckles. She really did blush a lot. Now she was back to gently wanking my cock and giving me an amazing feeling.

"I didn't think I was, remember your mate turned me down, if he hadn't we might not be here doing this now," she said.

"Well I am sort of glad, he did."

"You are? Really? You're not just saying that?"

"No, of course not."

She had gone much further than I thought she might, so I went a bit further still.

"Can I, umm, can I touch you too?" I asked, knowing that she had liked it last time.

She nodded.

I leaned forward and cupped one of her breasts, eliciting a soft sigh from her. I found her nipple which was already fully erect, a sign of the level of her arousal, and rolled it, gently squeezed it, and moved it around.

"There is more of what you called precum coming out," she said, as she ran her thumb up the back of my cock, squeezing several drop out, "is that because you're touching me?"

"That and the way you are touching me," I replied, "do you like what I am doing?"

"Yea," she whispered, "no one has done as much with me, it makes me very tingly down there, it's like my boobs are connected to those other bits of me, if you can understand that. Touching you at the same time make me feel more worked up too, and I know I am safe with you."

"Some girls like the taste, "I ventured,

"Of the precum?" she said, surprised.

"Well, yes, that and the real cum, you know the sperm."

"I'm not sure I like the idea of that," she said, screwing her face up a little. "Does Jayne like it?"

"I don't think she dislikes it."

"What do you mean," she asked, a bit curious now I thought.

"You do know that men like to have their, umm, penis sucked by their girl?"

"Some of the girls did giggle about 'blowjobs', and I sort of knew a bit, but not really what happened. Is it something you like? Does Jayne, do it for you, but doesn't really like it, is that what you are saying?"

"Jayne does it sometimes, and yes it feels really good."

"Does she do it all the way and you squirt it into her mouth?"

"Yes, I come, and she swallows it"

"What about the taste though? I am not sure I'd like it."

"Why don't you try a drop of just the precum on your finger, see what you think before we put the Durex on. It's another experience."

All this intimate talk with Sarah while she continued to pull my foreskin up and down, had my breathing increasing and I could feel my heart thumping away. It was something I shouldn't be here doing, but that just made it more exciting than ever.

I fondled, stroked, and massage each of her breasts and nipples in turn, noticing her increased breathing rate and occasional sighs. I did see her softly moving her thighs together more, just as she had the last time when she was getting really worked up.

Tentatively, she picked some of my precum up on her finger and gingerly put it on her tongue.

After a few seconds, "Ohh, it's not at all what I thought, it's not as repulsive as I imagined," she said. "I can see what you meant now by Jayne not actively disliking it, but it might take a bit of getting used to."

"Put the end in your mouth and see how it feels, you can almost say you have given a blowjob then," I encouraged her.

"I dunno, if I do, you promise not to squirt, I mean 'come' in my mouth, I don't think I want to do that."

"No, I won't, I promise." I said.

Then can we do the Durex?" she asked, getting nearer to my cock.

"Yes, that was what we were going to do wasn't it."

She moved even closer and put her tongue out, touching the tip of my cock with it and tasting a bit more of my secretion. I saw her will herself to do it, then open her mouth, guiding my cock with her hand between her open lips.

She put all of the head of my cock in, up to where the foreskin was pulled back, and closed her lips around it, fortunately keeping her teeth well away.

The sight and feeling of Sarah with her lips wrapped round my cock, for the first time with any cock, was very erotic. I wanted to push forward and bury it deep in her mouth as I did sometimes with Jayne, but I knew that would spoil it all.

Instead of moving it in and out, Sarah started to suck hard.

I think she saw my expression change.

She took it out of her mouth, "Am I not doing it right," she asked.

"To do it properly, you need to move it in and out gently, avoiding your teeth, and let your tongue move around it too, not just suck."

"Oh, I didn't know," she said, a bit chastened.

"Try again," I said, "if you want to."

She put it back in and this time flicked her tongue round it and bobbed her head a little, so it moved in and out as I had said.

"Yes, oh God Sarah, that's good," I praised her.

I felt the slight change in her lips as I think she tried to smile.

We continued like this for a while, she with my cock in her mouth and me making the most of her young breasts.

I could have carried on like that until I came, it would not take long, knowing it was Sarah doing it for the first time and not Jayne.

I had promised her though that I wouldn't come in her mouth, so reluctantly I thought we had better stop in case I did. Gently I pushed her back by her shoulders and felt my cock slide out of her mouth.

She looked up at me, "Was that ok?" she asked. "I think I got the hang of it. It's sexy for me too, knowing I'm doing this with a real guy, and he likes it," she added.

"It was incredibly good, a bit too good," I grinned, "I could easily have forgotten my promise."

She grinned too, "Wow, I didn't think I would be doing that," she said, "I quite got to like it. But what about the Durex now."

"Do you still want to do that?" I asked, thinking we might have already gone too far again.

"Yes, we're here now, I really want to try things with you, if you're ok with it. I have the packet here"

I got her to carefully tear it open and extract the condom. I showed her the small teat at the end that she needed to keep squeezed to keep the air out and to be careful with her nails. She placed it over the head of my cock and started to roll it down.

"It seems a bit stuck here," she said, as she encountered my rolled back foreskin.

I was just revelling in the sensation of her hands round my cock.

"Hold my cock, I mean penis, further down with one hand and try rolling it again," I instructed.

"Is that what you normally call it, 'cock'," she said, drawing the word out and grinning.

"Sorry, I said, it is less medical than the other word."

"Yes, I'll call it that from now on, I like it better," she said, managing to roll the condom over the ridge and further down my cock. "How far does it go down?"

"Right down as far as it can go, otherwise it may not stop everything."

"I think it's there," she said

It was. She had done it perfectly and I had got a lot of pleasure from it.

"It is, that's exactly how to do it," I said, "so now you know."

She had put her hand back on my cock and was slowly wanking it, watching how the condom moved.

"It feels a bit weird," she said, "does it feel different from doing it without?"

"Yes, a bit, but you don't notice it after a while, you know, when you are actually doing it."

"You mean when you are moving in and out of her."

"Yes."

Sarah let out a big sigh.

"I wonder what it feels like for the girl," she mused.

"I'm sure you'll find out one day," I said, still feeling her hand stroking my cock.

Nice as it was feeling her small hands wanking me, I was starting to think I should call an end to this now, we had had a bit of erotic fun and she had her answers. I still felt it was a bit risky, even though Sarah had said no one would be visiting.

"I think I should take it off now, and think about going home," I said.

"You said it can't be used again, it's a shame to waste it,"

"What? No, we can't have sex, that's just far too much. It would be your first time and I would feel more guilty than I do now. We can't do that." I said.

"No, sorry, I didn't mean go all the way, even I'm not ready for that yet, I just meant maybe we could do something like we did last time. With this still on, you could, come, and I'd love to see all your stuff in the end of it."

"No. I don't know," I mumbled, weakening, "it's a long way from answering questions or even showing you a few things."

"But it will only be like last time, you did enjoy it didn't you?"

"I said I did, but you're Jayne's sister, I should be concentrating on Jayne."

"You will when you are with her, I'm sure." she kept on.

"I don't think I should," I said, the little voice in my head getting quieter with the prospect of touching, stroking, and coming with this attractive girl.

She was determined. She stopped stroking my very erect cock, still covered by the condom, and took hold of her robe.

"Look, I'll even take this completely off," she said, and before I could intervene, slipped her robe down over her shoulders, lifted her bottom slightly, and pulled it out from under her, dropping it on the floor.

Oh my God, I was lost. She looked a bit vulnerable sitting there in only her black knickers, her nipples as hard as they could be, almost demanding to be sucked, and she was making all the running.

My balls were aching by this time with all the stimulation and as I had no intention of taking her virginity by putting my cock inside her. I gradually relented and put caution aside.

"Just this once then," I said, sounding reluctant, "but then I think we have done enough, and it stays our secret."

"Thank you," she said, "I promised only we will know, and I will stick to that. I would like to feel like I did the last time, it was much better than anything I've ever felt."

"Did you want to do what we did before then," I asked, getting down on my knees ready.

"Not quite, I want to lie down with you on top of me, like you did with Jayne."

"Ohh, do you think that's a good idea, it's a bit close to actually doing it," I said.

"Yes, as near as possible, but without actually doing it, that's the point."

My reluctance had now been replaced with more anticipation. I knew how we could do it, but wondered if she would want to.

"Hmmm, ok, but I don't think we should do any kissing, just let each other feel the sensations, is that ok?"

"Yes, I understand," she said.

She had already started to lie down and make herself comfortable, her head propped up on one of the loose cushions.

"Can you do one more thing, take off your shirt Pete," she said, "so I can feel your skin on mine."

I shrugged my shirt off and stood up, naked apart from a condom, and was aware she was looking me up and down, which was a bit disconcerting.

"Can you lie on top of me like you do with Jayne."

Sarah opened her legs as I climbed over her and I supported myself on my elbows on top of her. Her thighs were either side of me and her breasts touching my chest. My cock was lying on top of her knickers, pressing into her mound.
"Ohhh. Mmmm. I can feel you there, she said, this is so much better than you being in your jeans like last time," she said, squirming about to get into the most comfortable position.

I took the opportunity to move my head down and took one of her nipples in my mouth and flicked it around with my tongue.

She put one of her hands on my head and arched her back, so that her breast pushed more into my face.

"Yes, ohhh that's so good Pete, it's making me go all trembly," she said, breathlessly.

I alternated between nipples and licked round her areola; she made more moans of pleasure and attempted to press her groin upwards to press against my cock.

I started to move my own hips, rubbing my cock that was sandwiched between us, along her mound. It was awkward as the latex of the condom didn't slide very well on the dry front of her knickers.

She must have felt it too, as the latex snagged on her waistband.

"Pete, this isn't working too well," she whispered, above the sound my tongue and mouth were making on her nipples, "it's sort of not moving properly."

"Yes, I know, it's the two materials rubbing together I think" I said, letting a large erect nipple out of my mouth to speak. "I think we should just stop then." I added, regretfully.

"No, I want to try it like this, we need to make it work better."

I sucked her nipple back into my mouth while we tried to think of something, and resting only on one elbow, used my free hand to cup and caress her other breast. I knew no one had done this to her before and could see how much it turned her on.

"Pete."

"Yes," I said, looking up at her and seeing her biting her lower lip with indecision.

"Do you want to take my knickers off?" she blurted out, "I think it will help."

"You want to be naked with me?"

"It will be a bit embarrassing probably, I haven't gone anywhere near this far with anyone, but I don't want to stop now," she said, her neck and face going red again.

"Are you really sure you are ok with it," I asked, gently, but secretly thrilled that I may be seeing her completely naked.

"Yes, go ahead before I change my mind."

I pushed up off her to kneel between her legs. I gripped the waistband at both sides and as I peeled them down, she lifted her legs, putting her feet together in front of me, so I could slip them right off.

I could smell the perfume of her arousal now, and without making eye contact, she put her legs back in place either side of me. I could now see her very damp pussy for the first time.

She was a true redhead, with sparse, light, gingery, pubic hair. Her labia were plump, but not unduly so, and there was a sheen of moisture between them. She had a much more prominent clit than Jayne, which was already out of its hood and shining deep pink at the top of her slit.

It was a delicious sight and the thought crossed my mind briefly of taking her there and then, but we had agreed that wouldn't happen, and I knew she was a virgin and wanted to stay that way for the time being anyway. However, I did want to touch her there and I didn't think that was not allowed.

"Wow, Sarah, you look so sexy lying there," I almost hissed, moving one hand up her leg.

She flinched slightly and continued to look up at the ceiling. I let my fingers touch her pubic hair and trace the crease upwards. She was very wet just inside her lips. I fingered her gently, exploring her folds, opening her up so I could see the pink of her inner lips.

"Ahhh, ummmmm," she moaned, when I reached her clit, her hips moving with the sensation.

Letting my fingers drift downwards along her slit, I searched for her entrance. When I found it, I explored gently, but there was only a small entry to her vagina, whereas Jayne could take two or even three fingers if she was really wet.

Experimentally I attempted to penetrate her with one finger, but as I pushed in to just the first knuckle, Sarah took an intake of breath and put her hand on mine, stopping me from going further.

"That's uncomfortable Pete," she said, I haven't done...not even myself, it will hurt if you go any further."

I realised that she hadn't even used her own fingers or any of the things girls sometimes try, and I didn't want to hurt her. Withdrawing my finger slowly I moved my head forward instead and replaced my finger with my tongue.

I knew that Jayne enjoyed being eaten out and I wanted to see how Sarah tasted and if she liked it as much.

I soon found out both things.

She tasted sweet with a very slight tang of saltiness I thought. I loved the taste of her.

As soon as I started running my tongue up and down, then licking and sucking her clit, she gripped my hair and pushed her pussy up towards my face. She was making a lot of noise, panting, and crying out when I hit her clit full on. I probed her tiny hole with my much softer tongue but couldn't get it far inside her. I hoped the walls of the house were thick enough, so that no one could hear her, as it was obvious what was happening.

I didn't want to make her come like that. I still had the condom on throughout all this, so slowly I moved up her body, tasting her warm skin from pubes to stomach and back to her breasts.

Once I was lying on her again, the head of my cock was nudging between her pussy lips.

She looked me in the eyes, and I could see the apprehension there.

"You won't, will you?" she pleaded, her eyes saying the same thing.

"No, we agreed not to."

"Thank you," she whispered, I knew I could trust you.

"But we can do something," I said, "without me putting it inside you."

"How?"

"Close your legs, but not completely, and let me put mine outside yours, but first let me slip my shirt under you, otherwise there might be some explaining to do if the cushions get marked."

"Ummm ok."

I slipped my shirt under her and we manoeuvred into position.

"What now?"

I put my hand down and pushed my condom covered cock down the gap between her thighs, against her wet pussy. making sure that her pussy lips were either side of it, and I was snug against her.

"Ohhh, I can feel you right against me," she said, "that feels really good."

I moved slightly up her body, so that it forced my cock to point down, against its natural position. This increased the pressure of my cock on her pussy. I then pushed down until our pubic bones and hair met. Then I lifted my hips a few inches so that my cock slid over her clit.

"Oh my God," she said, as I pushed back down. "it feels as if you could be inside me, but I know you're not."

She put her warm hands on my bottom and held me to her, increasing the friction.

Gradually, I started a rhythm, slow at first letting her get used to the feeling. She caught on quickly and started to match my thrusts, wiggling slightly to get my cock exactly where she wanted it.

After only a few minutes, my cock was sliding nicely across her pussy, lubricated by the copious juices she was producing, that were leaking out of her, onto the parts of my cock in contact with her. The smell of sex was very strong, and I hoped it would be gone by the time anyone else came home.

"Ohhh sweet Jesus," she gasped, "I had no idea how this would feel. Ohhhh,.,.," she groaned, anew.

I lifted one hand that was supporting me and worked her nipple with my fingers; cupped and squeezed her breast more roughly.

"Yes, that's it," she hissed, "oh yes," through clenched teeth.

I felt and sensed the 'forbidden' nature of being naked with Jayne's younger sister and as near actually fucking as was possible. It only made it more exciting and erotic. I have never been able to get that thrilling picture and the feelings out of my head.

Both of us were now breathing heavily, and starting to sweat, each racing towards our own conclusion, but locked together in a joint venture.

She was thrusting her hips up as I was pushing mine down. Our pubic bones, her red pubic hair, and mine dark, crushing together each time.

I pinched and pulled her nipple and it only spurred her on to thrust harder.

"Pete, Pete, I'm c... .coming," she whimpered.

"Me too," I panted back, her imminent orgasm triggering the rush of cum up my cock.

Her thrusts got even more violent, lifting me up with her, as I felt her body shudder, and the first splash of my cum started to fill the end of the condom.

"Ohhhhh, owwww" she moaned, from deep within herself, and very loud.

She gripped my bottom pulling me tight against her, rubbing her wet pussy along my cock as hard as she could. As I spurted more into the condom, I could feel the muscles just above her mound flexing as she climaxed against me.

I just seemed to keep coming, pulse after pulse and she held on tight, ripples flowing through the parts of her body that were against me, her eyes tightly shut as she dealt with the sensations.

Slowly we both slowed down, occasional jerks of her hips and my cock flexing now and then, until gradually we both lay still, my cock still lodged tightly between her thighs.

I rested my face on the cushion, just over her shoulder, my lips facing, and close to her ear, her red hair damp with perspiration.

"Sarah, that was... was unbelievable, was it what you expected?"

She was quiet for a moment.

She finally opened her eyes, "I didn't know what to expect. Goodness, I don't know where that came from. Look, I am still trembling." She held up a shaky hand. "Is it always like that?"

"No, not always."

"Is it, umm, I mean is it like that with Jayne."

"Sometimes," I replied, non-committal, as in fact, Jayne didn't normally come like Sarah just did.

"But you do it with her for real though, it must be even better, isn't it?"

I gave it a bit of thought.

"Well, it is different," I ventured.

"How different," she persisted.

"It's difficult to explain."

"Try," she said, "I would like to know what's different."

"I think that, when I'm actual inside her, it feels more...ummmm.. like being joined with someone, part of them, so to speak," I tried.

"Hmmm."

"You'll know when it happens," I said.

"I suppose," she said, not really satisfied with my attempted explanation.

It was comfortable lying there with her, just quietly talking, although she did ask difficult questions. However, I could feel my cock slowly deflating, and I wanted to take the much-abused condom off, if it was still intact.

"I need to take it of now, before it leaks," I told her, starting to disentangle myself from her.

"Can I see what is in it?" she elaborated.

"Errr, yes I guess so," I said.

I extracted my wilting cock from between her legs and was relieved to see the condom wasn't damaged. Holding it tightly, as it was still covered in her lube, I slipped it off and held it up for her to see.

"Wow," she said, sitting up and gently squeezing the full teat at the end. "Gosh, there's a lot of your sperm in there, is there always that much?"

"It depends."

"On what?"

"Well, how recently I have done it before, that sort of thing."

"Ohh, so all that would have been inside me, if we had done it for real?" she mused.

"Yes, and that wouldn't have been good."

"No, I suppose not," she said, still touching it pensively.

"Sarah, I think I ought to go, time is getting on and it's time I was on my way home."

"Ok, thanks for ...ummmm, you know, everything," she mumbled, "you had better have this." she said, pulling my very creased shirt from under her.

I took it from her and noticed that as well as the creases, there was a large wet patch, that smelt very much of her, right in the centre of the back.

"It looks like you have something to remember me by," she grinned, pulling on her robe.

"Yes, I'll keep it close to me tonight," I said, smiling. "I'll see you later, I'm sure I will be here to see Jayne again soon."

"I am sure you will. I'll be around somewhere," she said, almost as a promise.

I wondered about the look she gave me...
My Girlfriend's Younger Sister Ch. 03
Sarah asks me to go much further.
All persons engaged in sexual activity in this story, are over 18 years of age.

This was based on a real event that happened in 1969 that is burned into my memory, when, bear in mind, there was no internet where anyone could readily obtain information like today. Only the descriptions have been embellished to make a more readable story. Reading Chapters 1 and 2 may give you a better insight into the story background. There is an element of cheating in the story, so if you don't agree with that, you don't have to read it, otherwise, enjoy.

Part Three.

After that episode with Sarah, for a few weeks afterwards, I didn't see her for more than a few minutes at a time. It was just enough to say hello, and that's about all. When I went to pick Jayne up, Sarah was either just leaving, or was ensconced in her room and didn't make an appearance. I wasn't sure if she was avoiding me or whether it was just coincidence.

About a month had passed since Sarah and I had been so intimate, and now the term had finished, and she had left school for good. Jayne told me that she was now spending a lot of time researching University courses and hoped to get a place at one of them in September.

Sarah not behaving normally was nagging at me, so one day I asked Jayne," Is your sister ok, she doesn't seem to be around much?"

"I don't know, I think she is ok, but she seems a bit moody at the moment, maybe it's because she is waiting for her exam results."

"Oh, maybe," I muttered, "only she normally comes and chats, but not so much at the moment. I wondered if I had done something to inadvertently upset her." I pushed, but not wanting to seem to be too interested.

"Hmmm, well, maybe I shouldn't really tell you this, but I think she went to the doctor and put herself on the pill. Because she is new to it, it could be it's affecting her mood at the moment. I am sure Mom and Dad don't know, so for goodness sake don't say anything."

"No of course I won't, but why would she do that? Do you think she has a boyfriend then and perhaps it's not going too well with them?" I probed a bit more.

"No, I am sure she doesn't," Jayne said quite firmly," I would know if she had. I think she is just setting herself up for when she is away from home, you know, if she gets a place at University in a few months' time."

"Oh well, I suppose that's wise," I said, but it did make me wonder.

Jayne working various shifts at the hospital, meant that I couldn't see her as often as I would have liked at conventional times, like other couples. However, if she were working from early afternoon, which was one of the regular patterns she did, then sometimes I could swap my own work shifts around a little to coincide with her.

Meeting in the daytime had its advantages, as the house was usually empty all day, so when we did get some 'alone time' together, they were often very amorous times. Now that Sarah had finished school and was home a lot more, Jayne wasn't too unhappy that her sister kept her own company and was not around much.

One day, Jayne was going to start work at 3pm, so we managed to arrange that I would go over to see her at about midday. We could chat; she would prepare a bit of lunch, and we could, 'get comfortable' as she put it, for almost a couple of hours afterwards. It had been over a week since I had seen her, and even longer since we had had the opportunity to do anything sexual, so I was looking forward to unhurriedly re-acquainting myself with her body.

***************************************

Jayne opened the door, dressed in a blue, super short, loose skirt - did I say she had stunningly long legs? - well she had, and most of them were on display this morning. She also had on a white T shirt, with some sort of logo on it, and although she didn't have very large breasts, there was no doubt she wasn't wearing a bra, as I could already see a hint of nipples pressing against the fabric. Her long dark hair was in a neat ponytail and hung down behind her.

Before we had even shut the door, I put my arms round her and squashed her to me in the hallway, kissing her hard on her lips, to which she responded enthusiastically. We broke the kiss and I continued to hold her against me, moving my hands around on her back.

"Let's go into the living room," she whispered into my ear, "Sarah is upstairs, I thought she was going out, but she is listening to music in her room, so we need to be a little quieter than I had anticipated," she said, as I felt her grin.

"Oh, I thought we might be alone," I said, a little disappointed, closing the front door.

"Don't worry, she seems to spend hours reading and playing music, we will be more or less alone," she replied.

We moved into the living room and I pulled the door closed behind us but thought that if I closed it, but left it unlatched, we could hear if Sarah came downstairs later.

We sat on the sofa as usual, the scene of various activities both with Jayne and Sarah, good job it couldn't talk, I thought.

We made some small talk about what she had been doing during the week, her future work times, and discussed tentative arrangements to try to go out one evening if it was possible. However, before long, we were kissing again, and my hands were roaming her back.

"Before we go too far," she said, with smile and an air of promise, "I think we should have an early lunch. I can take some upstairs to Sarah, and it's unlikely we will be disturbed then."

"Yea, sounds good," I replied, pulling back to allow her to get up and go into the kitchen, thinking that the 'not being disturbed' sounded very good.

Jayne had prepared several plates of various sandwiches as a light lunch, and before we sat down to have ours, she went and asked Sarah if she wanted to join us.

"Sarah says she will have hers in her room, so I'll just take a few up to her," Jayne said, when she returned.

I was surprised, but slightly pleased this time that her sister didn't want to join us, but it did seem to confirm that she might be avoiding me, as in the past, she had been all too happy to be with us.

"Is she ok up there?" I asked, when Jayne had taken some food up to her.

"Yea, she's recording pop songs from the radio onto her tape machine, she seems engrossed."

"Oh ok, as long as she is happy," I said, starting on the great, fresh, sandwiches Jayne had laid out in front of us.

We were both hungrier than we thought and before too long, the plates were empty, and we were finishing the drinks she had made.

"I'll just take these plates into the kitchen, and then we can relax a bit," I said, with a grin, and got a knowing grin back.

On returning to the sitting room, I saw that Jayne had taken her shoes off and made herself more comfortable by lying down on her back, along the sofa, with her head supported on one of the loose cushions at one end.

"Hmm, can I join you," I asked, knowingly.

"Oh, I hope you will," she said, "but remember, I have to go to work in a couple of hours."

I too slipped my shoes off, then lay alongside her on my left side.

"Glad you didn't put anything fishy in the sandwiches." I said, as I leaned over to kiss her waiting lips, "otherwise this might not have been as sexy as it is."

"It's why I didn't," she replied, giggling, as our lips touched.

I stroked her face with my right hand as we began to kiss and touch tongues. I could see in my peripheral vision that as soon as our tongues were dancing together, her nipples rapidly came to full erection and tented her T shirt, so that the no-bra scenario was visually confirmed.

I slid my had down from her face, over her collarbone and down onto her left breast, cupping it over her T shirt, the nipple hard against my palm. Rotating my palm, I massaged her nipple, feeling her react by sucking my tongue deeper into her mouth.

I knew from previous experience, that she liked her breasts touched first through the material of whatever she was wearing, and only then on bare skin.

I did this by moving from one breast to the other, sometimes circling the nipple with my fingers, sometimes tweaking them gently and returning to cupping the entire breast with my hand. I am sure that if they had been more pointed, her nipples would have pierced the thin material of her T shirt, they were so hard by then.

She was making very approving noises, muffled by our joined mouths, but still a little loud considering Sarah was upstairs. I reasoned though, that if she were listening to music, she probably couldn't hear us.

Slipping my hand under her T shirt, I pushed it up, and obligingly, Jayne lifted her arms allowing me to slip it over her head and drop it onto the floor. Both breasts were now exposed and although they weren't as big as Sarah's, they were still firm, warm and had much bigger nipples.

My cock had grown to full erection and was now pressing against her side through my jeans where I was sure she could feel it, but she hadn't made any attempt to touch me yet.

I did the same on her bare skin as I had over her clothes, causing more groans and restless shifting of her legs. She didn't really want to break our kissing, but I wanted to suck on those dark pink nubs, and once I got there, she held my head against them as I licked and sucked with fervour.

She was making increasingly more noise and her breathing was getting faster.

Now that my hand was free, I moved it down to where her skirt started at her waist, then ran it down and back over the small amount of her thighs that the skirt covered. As she felt me stroking her there, she opened her legs a little, obviously an invitation, which I took up.

Sliding my hand up under her skirt onto the bare skin of the thigh nearest me, with my fingers curled round between her legs, I stroke upwards until very soon, my fingers contacted her knicker-covered mound.

"Ohhh, mmm," she said, too loud for my liking, but letting me know she was enjoying it.

I could feel the dampness already. The outline of her labia formed a perfect camel-toe that my fingers naturally slid between, pressing slightly in, so that I could feel their plumpness either side of my fingers.

Normally, we would play like this for quite a while and she would touch and fondle me too, but judging by the sounds she was making, I felt that she wanted it to be a little quicker this time. Whether it was due to her need to be satisfied or the time constrains, I didn't know, but I thought I was reading her right.

Flipping her skirt up to her waist, I took hold of the waistband of her plain, light blue, knickers and tugged experimentally. Without hesitation, she lifted her bottom and I easily slid them down to just below her knees. Using her bare feet and toes, as only girls can, she shuffled them down and off onto the bottom of the sofa, leaving her in only her skirt.

Sometimes she was a bit reticent to go too far in our lovemaking in the living room, but today it seemed she had been missing it as much as me.

I was getting warm now, so as she did that, I took my mouth off her nipple and slipped my T shirt over my head. I could now feel her warm, soft, skin against mine.

Now that I had full access, I ran my fingers through her dark and slightly curly pubic hair, separating it either side of her slit. Dipping my finger down and under, I felt the moisture around her entrance and slipped my middle finger straight in.

There were more groans from Jayne and an upward shift of her hips, as my finger went in to the hilt. I could smell, as well as hear, her arousal now, probably one of the shortest times I had seen her get this way.

I went back to sucking on her nipples, flicking them with my tongue, while I began to slowly finger fuck her increasingly wet pussy. Two fingers curled up inside her, to reach her sensitive spot, was what she liked, and I lost no time in doing that to her.

She matched my fingers stroking in and out with thrusting her hips, panting with the effort and the sensations she must have been getting.

"Pete, I need to feel you in me now, please," she whispered, something she had never said before.

"I need to put a Durex on," I whispered, "otherwise we might make a mess as there is no cover on the sofa, just give me a minute."

She watched as I quickly stood up, flicked the button on my jeans open and ran the zip down. Reaching into my back pocket I took the condom out and then slid both my jeans and underwear off onto the floor.

"Ohh mmmm," she said, as she let her fingers drift down to her clit when she saw my cock bob up and point to the ceiling.

We were watching each other as I fitted the condom and rolled it down to the bottom of my cock.

Without even touching me, the sensuous way she had become so easily turned on to this extent, had me wanting to fuck her as deep as I could.

"Turn over onto your knees," I said quietly.

With a grin that told me she knew what was going to happen, she did as I asked, putting her tight bottom into the air, and burying her face deep into the cushion.

I climbed up behind her on my knees, between her legs, and rubbed the tip of my cock up and down between the very exposed lips of her vagina, that had now opened in anticipation. When the tip of my cock touched her clit a few times, she tried to move her hips and push back to get me inside her. I had never seen her so animated.

She moaned loudly; the sound muffled by the cushion.

Putting the tip of my cock right at her entrance, I pushed gently, feeling her warm tunnel start to expand around the head, as it was partially lost to view inside her.

As I moved my hips a little further forward and she pushed back, I suddenly caught a movement out of the corner of my eye. I swivelled my head and saw that the door from the hall was slowly and silently opening.

I paused, my cock head just resting inside Jayne, not saying anything. but wondering what had caused the door to open. I thought one of her parents might have come home unexpectedly, and a flood of thoughts flashed through my mind about what I was going to say and do, being caught with my cock half inside one of their daughters.

In the next moment, I saw it was Sarah dressed in her bathrobe.

She was almost in the room now, in bare feet and not making a sound on the carpet.

I ran my hands absently round the globes of Jayne's tight bottom, while I tried to process what was going on and what I should do.

Sarah was looking intently at where Jayne and I were partially joined, almost as if she had been invited.

"What are you doing?" I mouthed silently at her, thinking that perhaps curiosity satisfied, she might just turn round and go away.

Jayne was still slowly trying to thrust backwards at me and still groaning into the cushion, so I knew she wasn't aware of anything amiss.

"Don't tease me Pete," Jayne's muffled voice said.

I was still looking incredulously at Sarah who hadn't moved.

"Go on," she mouthed back.

I shook my head 'no'.

She nodded vigorously and took a step closer.

Then another step, she was now almost touching me and could quite clearly see the head of my cock just inside her sister.

She inclined her head a couple of times, urging me on.

I knew I had to do something, and I certainly didn't want Jayne to know she was there and have some sort of major, sister falling out fight.

You know how time slows down sometimes, well, since Sarah had appeared, all of the above had only taken a few seconds rather than the minutes it seemed to be.

My initial shock has lessened, knowing it wasn't one of the parents and Sarah didn't seem as if she was going to say anything, or go any time soon. I did the only thing I could before Jayne realised something wasn't right, I pressed my cock further into her, while watching Sarah's flushed face.

She was biting her lip and massaging one of her breasts through her bathrobe.

Jayne moaned louder when I bottomed out in her and then withdrew to plunge fully back, my balls slapping her pussy lips.

Sarah peered closer and undid the belt of her bathrobe, letting me see she was totally naked underneath. Her neatly trimmed red bush was hiding the lips of her pussy that my cock had touched some weeks ago.

Her hand was now on her bare breast, pulling at her nipple while her tongue continually wet her lips, her attention totally focussed on my cock moving in and out of her sister.

Now that my stress level had reduced to normal, I realised that although I wasn't in any way an exhibitionist, I was beginning to enjoy the eroticism of having her younger sister actually watching us, instead of me just answering her questions.

When I pulled backwards, I deliberately let my cock almost leave Jayne's pussy so that Sarah could see her sister's labia wrapped round the head, then be pushed inwards as I thrust in once again.

My only worry was that Sarah might make some noise and alert Jayne that we weren't alone, but as I said on a previous occasion, Sarah was a smart girl, and she wasn't about to spoil her fun by being careless.

I watched Sarah's other hand creep down her stomach and into her pubic hair, then her finger started to rotate on where I knew her clit would be.

With Jayne wanting to be fucked so badly, and Sarah's antics beside me, my cock was as hard as I could remember it being. With one of my hands holding her hip, and the other pulling on her ponytail, I started to fuck Jayne harder.

We had never fucked hard like this before, and I thought she might complain, but she met me thrust for thrust. She seemed to be loving it, and her noises grew, even though her head was in the cushion.

"Yessss.. Pete, oh yes," we both heard from Jayne.

Sarah's eyes were bright and her face a livid red, as she fought to not make any noise. She knew we were getting close and was about to witness me and her sister coming together for real.

I felt Jayne's legs start to vibrate against mine, her hips slowed down, but she pushed back really hard each time, as her orgasm approached.

I felt it too, deep inside, like pressure building for release and waiting for the safety valve to open.

Once I felt Jayne's vagina start to clench on my cock, that was all it took.

As she hit her climax, I rammed my cock as far into her as I could, the first jets of sperm shooting into the end of the condom deep inside her.

I know she tried to keep her voice down, but if Sarah hadn't already been in the room, I am sure she would have heard her as the main force of her orgasm hit her.

Sarah was open mouthed, watching avidly and rubbing her clit round and round as fast as she could. When she saw and heard us coming together, she took a big intake of breath that was very noticeable, but I think Jayne was fortunately too far into her own pleasure to notice.

Again and again I felt the wad of cum ripple up my cock to spill into the inside of that latex teat that was pushed against Jayne's cervix.

My cock gradually stopped pulsing so violently and only occasional weaker spasms continued.

Jayne let her knees slowly slide backwards with me still inside her, until she was lying on her stomach and I was virtually lying on her back. I moved gently and slowly inside her a few times, my cock still erect and solid.

I knew that she would soon want to turn over once the final small aftershock had past, so I looked up at Sarah and flicked my head in a 'go now' gesture.

I nuzzled Jayne's neck for a few moments and when I turned to look again, Sarah had gone, and the door had closed as silently as it had opened. I didn't know if she had come too, or whether she had gone back to her room to replay what she had seen and continue alone, but I was relieved that she was no longer there to be discovered.

Gradually my cock softened and slipped out of her, so I gripped the elastic ring, sat up and removed the very full condom while Jayne turned over with a very satisfied look on her face.
"Wow, Pete, that was something special, but I think I made a bit of noise, do you think Sarah could have heard?" she asked.

"I think I can still hear her music," I said evasively, "and I doubt she will want to say anything even if she did."

"That's good," she replied, "what about the sofa, did we make a mess?" she asked, becoming more practical.

"I can't see anything, but I think you may need to change your skirt, it has something on it, but it saved the sofa."

"Oh that's ok then, but thinking about that, I think I need to get changed for work, can you give me lift there please, I feel a little wobbly after that," she grinned.

Jayne gave me a kiss and then went upstairs to change. I don't know if she looked in on Sarah, but I didn't hear anything from up there. I put on my clothes and sat back down on the sofa to wait.

When she returned, she was wearing her nurse's uniform and looked every bit the respectable professional that she would be on the wards, rather than the person had just enjoyed being fucked hard and quick.

I took her to work in my car, said a fond goodbye with a few kisses, and then drove out of the hospital grounds to make my way home.

It was at this point that a little voice in my head said, 'Don't you want to find out what Sarah was up to?'

I slowed down the car, the choice to just go home, or go back to the house and confront Sarah, batting back and forth in my head. I knew their parents never got home before 6pm, so there were a couple of hours yet to talk to her if I did go back.

The voice got louder.

Yes, I did want to know what that was all about, it had been very risky on her part and then she had involved me in her game, which could have turned out differently. Then I thought, but... I had found it a big turn on for Sarah to have watched me fucking her sister for real. I had come hard, knowing she was watching.

The images of her standing there in her bathrobe, then opening it; the red triangular bush contrasting with her light skin, her fingers sliding through it, her eyes glued to my cock sliding in and out of her sister. My mind wandered.

A loud blast on a car horn brought me quickly back to the real world. Shit! I had just driven straight over a STOP sign at a junction. That was a close thing, I pulled over and stopped to get my concentration back.

Once my adrenaline had dissipated somewhat, I sat and thought about what to do. I wasn't sure what reception I might get from Sarah, but with butterflies in my stomach, and a sort of anticipation of at least some sort of sexy chat with her, the voice in my head won, and I carefully made my way back to their house.

There was a delay when I knocked on the door, but eventually Sarah opened it, surprise written all over her face.

"Pete, what are you doing back, did you forget something?"

"Err no, not exactly, but could we talk for a moment or two?"

"Emmm, sure," she said, not actually moving.

"I think it might be better inside, where the neighbours can't see you chatting to me in your bathrobe," I grinned, taking in the sight of her dressed just as she was earlier, and I assumed with nothing underneath.

"Oh, yes. Of course, sorry, come in please." she said, closing the door after us.

We went through to the living room, the scene of her voyeurism only a short time ago, and we sat side by side on the same sofa.

"Ummm, what do you want to talk about," she said, a faint blush creeping up her neck already.

"I think you know." I said, looking her directly in the eye.

She looked down at her hands in her lap, "I guess about earlier?" she said quietly, "are you annoyed with me?" her face now going red too.

"Hmmm, I think I should be, but do you want to tell me what that was all about? It's not normal behaviour to creep in and watch two people having sex, is it?"

She was quiet for a moment, and I wondered if she was even going to say anything. I stayed quiet just looking at her, but she wasn't meeting my eye.

"I'm sorry," she started eventually, "it was just that, umm, I heard you both again from my room, and after what you had told me, and the things we did, I had this sort of urge to see it happening, you know, for real. Are you really mad at me?"

I thought about it for a short while, still not saying anything, while she seemed to be squirming now with embarrassment at being confronted with it.

"Sarah, we have done quite a few things we probably shouldn't have done, so I suppose I am partially to blame, so no, I'm not annoyed with you, I guess I was shocked at first to see you there."

"So you didn't really mind me seeing you with Jayne?" she said tentatively, looking back up at me.

"I can't say it's something I am used to," I said, a slight grin on my face now, "if I am honest, it might have been a bit of a turn on too," I added.

"Really?" she exclaimed, looking slightly relieved.

"How about you, did you find watching was sexy, or did it just satisfy your curiosity?"

"Well, it did both I suppose," she said, "but it made me feel something more."

"More? What do you mean?"

She bit her lip shyly.

"You won't be shocked if I tell you?"

"After what we have talked about and done before, I doubt you can shock me," I said, wondering what she was going to say that she even thought might shock me.

"The last couple of weeks, I haven't been around much when you were here," she started.

"Yes, I had noticed, I sort of assumed you wanted to keep your distance after the last time we did stuff."

"No, no, you've got it wrong, it's the opposite really." she said, her freckles contrasting against her very red face.

"Now you've lost me."

I could see her plucking up courage to say something.

"Just over a couple of weeks ago, I went to the doctor and asked to be put on the pill, like Jayne."

"Oh, ok, I see," I replied, knowing now that this confirmed what Jayne had thought, "but why do it now?"

"Because," she paused, took a deep breath, and said, "after you showed me how good you can make me feel, I wanted to feel it all, like Jayne does. There I've said it." she finished, letting out her breath.

I wasn't sure what to say to that, I knew she hadn't had full sex yet, but seemed to be telling me she was about to.

"OK, ummmm, well you are an adult, so I guess you can do what you want, but I didn't think you had a serious boyfriend yet?"

"No, I don't," she looked down at her hands again, "that's why I want you to go that last step with me."

I paused while my brain processed what she had just said.

"What? Are you serious?"

"It's what I have been thinking about for the last couple of weeks, and when I saw you and Jayne earlier and how much she was obviously enjoying it, it made my mind up."

"But we can't, it's not like the things we were doing before, I mean,... if I, you know, do what you are saying... it's not something we can undo or forget."

"Yes I know that, but I would feel safe with you, and as we've said before, no one is ever going to know."

"I would know, and you would," I said, playing for time, and trying to get my head round what she was suggesting, but also feeling the first prickles of excitement realising that she wanted me to have sex with her.

"What about Jayne," I continued, "won't it be weird afterwards, I mean, we can't have an ongoing relationship if I am having a serious relationship with your sister."

"I know that too, and she'll never know, you can trust me, like I trust you," she coaxed.

My cock was already thinking for itself and growing in my jeans. I had been with a few girls, but none of them were virgins, and to be honest, I was a bit nervous, but she was an attractive and sexy young girl, and it would be very exciting to be her first.

"It might hurt though, for your first time," I tried.

"I know you will be gentle, it's another reason why I want it to be you, rather than some guy I might meet at University, who may not be as caring as you," she countered, "please Pete, I have been plucking up courage to talk to you about it, and although I didn't know you would be coming back, it was really sexy seeing you and Jayne today, I want to feel what she was feeling."

She looked down at her hands in her lap, embarrassed at having been so forthright.

My cock was now fully erect and pressing painfully against the inside of my jeans, reminding me that it was there and ready to be put to use.

"We can't do it here anyway," I said, " it's too risky and anyway it might be a bit. ..messy," I finished.

She took my hand in hers and I immediately felt the warmth of her smooth skin. "Come up to my room," she said simply, and stood up, pulling my hand with her.

Seeing her standing there, looking down at me, excitement, and a little bit of nervousness in her eyes, I knew we were going to do it, and I slowly stood up too, my cock making a large bulge in the front of my jeans.

She looked down and smiled slightly, then drew me towards the door to the hall and staircase.

I went up the stairs behind her, watching the back of her bare legs to where they disappeared under her bathrobe. We turned right at the top and entered her bedroom, that I had never been in before.

It was warm, and I noticed that it was immaculately tidy and clean, no clothes strewn about, and the bed made, neat and smooth.

Having closed the door behind us, we stood there, the bed being the 'elephant in the room', and despite our conversation of only a few minutes ago, there was a sort of 'awkwardness' about what to do next.

Although I had previously said to her when we were doing all the other stuff, that we couldn't kiss as it wasn't that sort of relationship and she had agreed, I felt that this time it had to be different.

I moved up close and putting my arms around her, gently pulled her to me, until our bodies were touching, nose to nose, my hard cock pressing through my jeans against her mound and stomach. Moving my head sideways, I pushed her hair away from her neck with my nose and nuzzled her neck with my lips, feeling the fine short hairs there, tickling them, and was gratified to feel her shiver and goosebumps immediately appear along her neck and shoulder.

I used my lips to nibble at her neck, moving up until I found her earlobe. She leaned her head away from me, stretching her neck, and giving me access to even more skin, while letting out a quiet sigh.

As I gently bit her earlobe and ran my tongue around it, I lowered my hands, one on each globe of her tight bottom, and pulled her tighter towards me. She followed suit, forcing my hard cock to press against her.

I felt her open her legs a fraction, enough for my erection to rest further against her. Nuzzling slowly round from her neck to her face, I nibbled at the corner of her lips. I think this surprised her.

She straightened her neck and turned her face more towards me which put my lips directly against hers. I kissed her fully on the lips and felt her respond. I could see confusion in her eyes as I pressed my tongue against the opening of her lips. I was sure she was remembering the 'no kissing' conversation.

I simultaneously moved one hand up to cup her right breast over her bathrobe, and pressed my tongue against her mouth, that she quickly relaxed to let me in. I saw the confusion in her eyes disappear and a sparkle take its place, the corners of her eyes crinkling, as she realised that the rules had changed.

Now she took a bit of a lead, joining her tongue to mine, our lips pressed tightly together while my hand teased the nipple I could feel, even through the bathrobe.

"Ohhhh," she breathed out, before sucking on my tongue and stroking it with hers.

Moving my hand down I found the bow of the tie -cord for the bathrobe and tugged at it, feeling it come loose. Stepping quickly away just a little, I was able to pull one half of the it open and put my hand underneath against what I found was bare skin. She hadn't put on any underwear since I had seen her earlier.

I moved my hand back to caress her breast, but this time touching her skin, and able to fully feel the hardness of her nipple.

Putting my arm round behind her, I stroked her back, her bottom, her hip, and back up to her breast. She kissed me with even more vigour as I roamed her sexy warm body with my hand.

While doing this, I moved her slowly backwards until the backs of her knees touched her bed, and as a reflex she sat down. I bent with her, keeping contact with her lips.

Breaking our kiss, I pushed her gently back onto the bed and lifted her legs up with my other arm. She quickly understood what I wanted and shuffled over on the bed, to make room for me to lie down beside her.

Her bathrobe had opened completely in the process, displaying her light freckled skin, darker nipples, and her red triangle of pubic hair.

Before joining her, I quickly slipped my T shirt off for the second time today, and unzipping my jeans, dropped them to the floor, leaving me in just my underwear.

I lost no time in lowering my mouth to suck on one of her nipples, feeling it hard between my lips; cupping and stroking the other one with my hand. She began stroking up and down my back, and with our bare skin touching each other, these sensations quickly got her back to her previous level of excitement, and she began moaning afresh.

Stroking down her body from her breast, I felt her shiver as I passed her hip and continued down her upper thigh. Keeping away from her mound, I let my hand wander up and down each leg, teasing her, by allowing my fingers to slip between her legs each time, until I got close to her pussy, and then sliding them round her leg to avoid touching her there.

She opened her legs a few inches and shuffled a little, inviting me to touch her, and eventually I relented, trailing my hand up through her pubic hair, lightly combing it with my fingers. Lower down, I could feel the wetness already dampening the hairs, that was spreading upwards with my touch.

I felt her pushing at the waistband of my remaining garment that would free my cock from its confines, so, removing my hand, I helped to push my underwear down and off.

My hard cock dropped onto the skin of her thigh and hip, where her hand found it, and slowly started to slide the foreskin up and down.

I increased the sexual tension by leaning up and kissing her again and simultaneously sliding my fingers down between her legs, finding her puffy labia wet and waiting.

"Mmmmm, ohhhh, Pete," she mumbled through our joined lips, and like Sarah, I too was turned on now, lying naked together with Jayne's sister, more of our flesh touching and knowing where this was going.

I was now sliding my very well lubricated finger up and down her slit, but I remembered that she had found it uncomfortable the last time I had tried to insert my finger in her when we were downstairs on the sofa that time. As I felt her getting wetter by the minute, I gingerly pressed the tip of my index finger against her entrance and feeling it give a little, pressed a little harder.

Instead of stopping me, Sarah opened her legs more and helped by angling her hips upwards towards me.

With the lubrication helping, the first part of my finger slid suddenly and smoothly into her warm tight tunnel. She kissed me harder, gripping my cock a little too tightly, and swirled her tongue in my mouth.

She seemed ok with it, so very slowly I let her movement and a little pressure, drive my finger little by little, deep inside her, until it was totally buried.

"Is that ok?" I asked, pulling back from her kisses for a moment.

She nodded.

I began to move my finger in and out of her, gently at first, letting her get used to it, and watching her face and eyes for any sign of discomfort, but all I noticed was that her breathing had increased, and she had closed her eyes. She continued to rub my cock, occasionally sliding her thumb over the top, using the copious amount of precum as a lubricant.

I really needed to try to get a second finger inside her, as I knew my cock was going to be even bigger than that, and I wanted her to be more used to it when I tried.

Making sure it was as wet as the first one, I put it alongside its neighbour and wiggled the tip as I attempted to press it in.

Sarah screwed her eyes up and tensed, so I stopped, her inner lips just spread a little around the tip.

"Go on," she whispered, "but slowly."

I pushed as gently as I could, wiggling both fingers until gradually I felt the tight muscles of her vaginal canal pressed tightly around them.

Sarah let out a breath and a sigh.

It seemed that once they were inside her and she was stretched around them, then the initial pain of penetration eased and I was able to slide them further inside, a small amount at a time, until they were both in, side by side, as far as I could get them.

She was so tight, I was wondering if it was going to be too uncomfortable for her to have my hard cock in there, but for the moment, I began slowly finger fucking her with the two fingers.

The sliding got easier as she got even wetter, she pushed her hips up to meet me, and was making a lot of noise. The feeling of my fingers going right up inside her, had distracted her from stroking my cock and she now had it just resting in her hand.

It's strange that we didn't say much, and even if we did, it was in a whisper, as if someone would hear, even though her moans and grunts were becoming louder than our words.

I thought I would help her lubrication with my mouth and tongue, so I slipped one leg over hers and then the other, until I was lying between her legs, my fingers still buried in her pussy. Her eyes opened to see what I was doing, and I think she thought I was going to try to fuck her already, but as I slid down until my mouth was level with her pussy, she relaxed again.

I could smell her strong arousal as I first nuzzled her red pubic hair with my nose. With my fingers still inside her, the only place I could see to touch with my tongue was her erect clit. I remembered from seeing it before that it was slightly larger than Jayne's, and with its hood right back, it made a large target. It looked this time as though it was even bigger, as it was very prominent. I pushed my tongue forward until I contacted it with the tip and then pushed it upwards, running my tongue over it.

"Ohhh, arrrg, Pete!" she almost squealed, bucking her hips at the same time.

Keeping my fingers still, I licked around it, my saliva mixing with her own juices. She tasted as good as the last time, but perhaps with a little stronger flavour. I sucked it into my mouth, flicking it side to side as I did so.

It sent her wild.

She gripped my hair, pulling me against her, and at the same time, pushing her hips upwards. My fingers that were buried tightly inside her were forced even harder upwards, so that the tips just touched the end of her cervix. She seemed now to be only feeling the pleasure. The initial discomfort of me stretching her seemed to be a distant memory.

I resumed gently finger fucking her as I ate her out and could feel my saliva dripping onto my fingers, aiding the slipperiness of her own secretions.

After only a few minutes, I knew that if I continued she would come, and I wanted to delay that, so I slowly withdrew my fingers and moved my mouth down level with her entrance and began probing it with my tongue, getting her wetter and wetter.

She was breathing very heavily and trying to pull my head back to where it had been so that I would lick her clit, but I steadfastly resisted, and instead lapped at her wet pussy lips, until my chin and lips were covered in the liquid mixture.

All this time, my cock had been rock-hard, but not receiving any attention, as she couldn't reach it in the position we were in. Seeing that she was a long way along the road to orgasm, I wanted to feel my cock against her and see how she reacted.
Gently prising her hands from my head, I knelt up between her legs and looked down at the puffy outer lips of her pussy, her wet pubic hair now lying flat and dishevelled. A small amount of pink from her inner lips was already showing, but I was surprised by the amount of liquid we had generated, dribbling out of her slit onto the open bathrobe that was still under her.

Again, she looked slightly nervous when I put my hands under her thighs and slid her towards me, opening up her legs even more. My cock was now only about an inch away from touching her pussy. By shuffling a little and using one hand, I slid the head of my cock up against her wet labia and slid it up and down. The head easily slipped between her outer lips as I moved it, catching her clit unawares at the top of each passage.

Her body twitched at that.

"Oh Pete, that's so much better than last time, feeling you actually against my skin.. down there," she whispered.

After teasing her for a few minutes and getting my cock fully lubricated, I pressed a little harder each time I passed the entrance to her vagina, making a small part of the head just penetrate her fractionally. She was enjoying the sensations and the situation so much, that I don't think she noticed I was penetrating a little more each time.

It was very erotic, and such a turn on, to watch in close up, my cock head sliding along Sarah's pussy. Each time I pressed in, I felt like I wanted to just force my whole cock deep inside her. However, I took my time, slipping, sliding, and moving the folds of her pussy around with the head of my cock.

Sarah had closed her eyes again and was groaning and moaning, her head moving from side to side as I stepped up the pace. Each time I pressed in, I thought that this time my very well lubricated cock head would go right in, but even now she was tighter than I thought.

The next time I pushed, I pressed that bit more. Almost like pressing my finger through a plastic bag, I felt

the tension giveaway and saw my cockhead disappear inside her, followed immediately by two things.

The first thing was that Sarah's eyes shot open and she gripped my thighs, "Owww, ohhh, God," she exclaimed loudly.

The second was that I felt my cock being gripped tightly, like having a very tight elastic band just under the ridge of my cockhead.

"Stop," she said, panting, "just hold it there a minute."

"Are you ok," I asked, worried that I might have hurt her.

"I think I am," she said, her eyes moving from side to side, "are you really in me now Pete?"

"Only a little," I said, looking down at where my cock still rested between her pussy lips, the head just inside her.

"It feels so...so.. stretched," she said, quieter. She started to push herself up on her elbows, "I want to see?"

I stayed still, trembling slightly, my cock pulsing now and then while Sarah lifted her upper body until she could see down to where my cock was parting her pubic hair, partially inside her.

"Wow, Pete, oh my good Lord, that is so sexy, I can see your penis is actually in me. Ohhh," she stared at it.

"Am I... hurting you?" I stuttered.

"Not exactly," she said, still looking, "it's sort of a bit tender I guess, but not really bad. Ahhhh, I can feel when it pulses like that," she added, with a small smile, as I involuntarily flexed my cock muscles, causing it to try to move up and down.

We stayed like that for what seemed like a long time, but probably wasn't, just looking together at where we were joined, and where she had a real cock inside her for the first time.

"Try a bit more now," she suddenly said, as if making up her mind.

"You're sure, I can take it out if you want," I answered.

"No, I want to try, please."

She watched as I pressed forwards a little more, and now that the head was in, her vagina stretched more easily to accommodate another inch.

"Ohhh, yea, Oh Pete, I tried to imagine what it might be like when we did those other things, to actually have you inside me, but I couldn't."

"And now, how do you feel?"

"I feel I want you to do it properly, like you do with Jayne, so I don't have to imagine anymore. Is that weird?"

"Not as long as you are alright with it," I said, pushing gently, forcing more of my cock to go in.

She laid back down.

Allowing my cock to pull almost out, I slid my knees down the bed so that I was lying between her wide-open legs on top of her, supported on my knees and elbows, looking into her eyes. As my cock was still in the right place, I pushed my hips down and this time my cock entered her more smoothly and even a little further than last time.

Sarah sighed and opened her mouth. I immediately covered hers with mine and she responded by kissing me hungrily and wrapping her arms around me.

As I kissed her, and our tongues re-commenced twisting and dancing with each other, I gradually pressed my body into hers, feeling the delicious sensations as my cock was enveloped by the hot walls of her vagina.

Slowly but surely, she took all of me, until our pubic bones were pressed against one another, and my balls were touching her.

"I can feel you so far inside me Pete," she said, through our kissing, "I've never felt anything like this before, try moving, but slowly at first."

I did as she asked, and slowly withdrew, just leaving the head inside, then smoothly, but not too roughly, slid all the way back in.

"Mmmmm, ugggg," she muttered, into my mouth.

I sucked her tongue, tickled it with mine in time to my movement in and out of her, and slid one hand up to caress her breast and tease the hard nub of her nipple. I could hardly believe I was really fucking my girlfriend's young sister, and I was her first.

All reticence seemed to have left her now, as she started to meet my thrusts with her own, crushing my pubic bone against her clit and forcing me deep inside her.

Even though I had ejaculated earlier with Jayne, I knew I wasn't going to last long with Sarah, as the knowledge of what I was doing, and the sensation of moving my cock in and out of such a tight pussy, was driving me close to the edge.

She started to speed up her thrusts and the thought briefly flashed through my mind that being the first time, she was going to be sore afterwards, but I kept pace with her.

"Pete, Pete," she cried out, "I'm going to come, yes, yes, Oh God, Oh God."

I felt her start to shake, just had she had done when we had messed about before, but stronger. She gripped my back, pulling me to her and raised her knees either side of my thighs, thrusting upwards, trying to lift me with her hips.

My cock felt as though it was being gripped. and as she was holding onto me with her arms, I wasn't able to pull very far out, so settled for leaving my cock deep inside her, and letting her rub her clit against me as she reached her peak and her release.

She was making incoherent noises and thrashing about, and that finally tipped me over too.

I felt the second lot of cum for the day being pumped up my cock and spraying into Sarah. I didn't need to move, as she was doing all that was necessary. I just held my cock as deep inside her as I could and felt the built-up tension being dissipated with every spurt.

"Oh, fuck, fuck," I gasped, the gratification of the moment overcoming my normal reluctance to use words like that.

She kept jerking her hips every now and then as the main peak diminished and the small aftershocks hit her, causing me to reciprocate with small thrusts after each one.

Slowly she stopped twitching and lay underneath me trembling.

Now that her vagina was full of my sperm and her juices, it was easier to move and I tried a few gently movements in and out.

"No, Pete," she whispered, "I'm too sensitive and a bit sore now, just stay inside me as you were, I want to just feel and know that I have finally had you inside me."

I didn't know what to say to that, so I let a little of my weight rest on her hips, feeling my cock start to soften and kissed her more gently than before.

I don't think either of us knew what to say next, so we lay there quietly together, just holding one another and relaxing.

Eventually my cock began to slide out of her, followed by a stream of mixed liquids, that dripped onto her bathrobe still underneath us.

I slowly rolled off her onto my side and pulled her close, the front of our bodies touching, into a tight embrace. Stroking her back and kissing her lightly I let my hand roam over her body, lovingly stroking her.

"I hope you don't regret it now," I said quietly, wondering how we were going to act around each other in the future.

She was quiet for a moment, "No Pete, it was something I wanted to do, I didn't know how it would feel and... it was more than I had imagined by a very long way. I am glad it was you, and I feel a special bond now, but don't worry, I am not going to say anything or stalk you," she smiled and paused. "I won't ever forget it though. I hope we can stay close, even if we're not going to do this again."

"I'd like that," I said, genuinely touched.

******************************************

EPILOGUE.

Sarah went off to University later in the year.

I did marry Jayne the following year, with Sarah as the chief bridesmaid. She is of course, now my sister-in-law.

Sarah talks to me as a close friend and confides in me if she needs advice, or just to talk things through. She knows she can talk to me about anything. She has often visited and stayed at our house with me and Jayne.

She found a good guy and got married herself when she finished University, and now, like us, has two children and is very happy.

We often meet at family gatherings, where sometimes she gives me a look, directly into my eyes, telling me that she remembers, but she has never mentioned it again, and we have not had any further sexual relationship...so far...
My Girlfriend's Younger Sister Ch. 04
I never expected more, but Sarah had other ideas...
All persons engaged in sexual activity in this story are over 18 years of age.

The first three chapters were based on a real event that happened in 1969, that is burned into my memory, when, bear in mind, there was no internet where anyone could readily obtain information as you can today. Only the detailed descriptions have been embellished to make a more readable story (my memory isn't that good). Reading these previous chapters may give you a better insight into the story background. There is an element of cheating in the story, so if you don't agree with that, you don't have to read it, otherwise, enjoy.

Part 4

At the end of part 3 of the story, I brought readers up to date with what had happened since, as an 'epilogue', it read like this...

'Sarah went off to University later in the year.

I did marry Jayne the following year, with Sarah as the chief bridesmaid. She is of course, now my sister-in-law.

Sarah talks to me as a close friend and confides in me if she needs advice, or just to talk things through. She knows she can talk to me about anything. She has often visited and stayed at our house with me and Jayne.

She found a good guy and got married herself when she finished University, and now, like us, has two children and is very happy.

Our two families sometimes go on holiday together and often meet at family gatherings, where sometimes she gives me a look, directly into my eyes, I think she is telling me that she remembers, but she has never mentioned it again, and we have not had any further sexual relationship...so far...'

******************************************************************

At the time, I didn't expect anything more to happen and it would remain just a memory.

The events in the previous chapters had taken place over a few weeks, about a year before Jayne and I had married and then subsequently had children. It was a good memory, shared only with Sarah, my now sister-in-law, that I admit I thought about from time to time. I did wonder if she ever thought about it, but although, as I mentioned, she sometimes gave me a strange look when we were at family gatherings, it hadn't gone further than that, so I didn't know if she did or not.

I didn't realise that I was about to find out...

Jayne and I had waited just over four years before having our first child, and Sarah had got married to Rob the following year when she was 25. Unlike us, she became pregnant very quickly, a bit of a waste of that University Degree I thought, but they seemed happy enough with the situation. A second child followed for both of us couples, so there wasn't much of an age difference between Rob and Sarah's children and our own. This meant that the two sisters had plenty in common and spent a lot of time helping each other out with child-minding and the like.

Family gatherings were great, and the grandparents loved having four grandchildren to spoil and fuss over.

Unfortunately, fate played a bad hand a few years later.

Jayne and Sarah's dad keeled over one day with a fatal heart attack. We all rallied round to support their mom over the following weeks and months, but it was never the same.

After about nine or ten months, she decided she wanted to move to a smaller house, and with help from us all, finally chose a small bungalow in the same area.

Rob and I took a few days off work, and we all took turns, as couples, to help her with the packing, moving, and trying to downsize the considerable amount of 'stuff' they had accumulated. We took turns to look after each other's children, who had a fun time playing games with each other, while the other couple were occupied at the house with their mother. It was hot work in the warm July weather, running up and down stairs with various items destined either for her new bungalow, the charity shop or for disposal to the nearby rubbish tip, whichever she decided, but between us all, we managed it ok.

We finally got their mom installed in her new home, and there were only a few things left to sort out in the old house before the new owners were going arrive in a few days time.

"Pete, could you give Sarah a bit of help tomorrow afternoon? She wants to go and check that nothing has been overlooked and also take a vacuum cleaner, to do a final clean around the place. The house clearance guys are coming the day after to get rid of all the heavy furniture and beds that Mom doesn't want," Jayne said, the evening we had made a final trip to the rubbish tip.

"Isn't Rob around then?" I asked.

"No, he has to go to some sort of work related, all-day meeting, that he says he can't get out of, and I am going to look after all the children," she said.

As we only had one car each, it wasn't unusual to be helping out by giving a lift to each other and it seemed to balance out over the year.

"Yea, ok, I did have a few things planned as I thought we had finished, but sure, I can do that, then I guess it's finally all over with, and the new owners will be moving in," I said.

She was quiet for a moment, and catching on to her suddenly sad mood, I realised I had been a bit insensitive. To me it was just a house where she and her family had lived, but to her, it was where she had grown up, had built lots of memories and was much more personal.

"Sorry," I said, going over to give her a hug, "I understand its the end of an era for you and Sarah, would you prefer to go with her, and I'll look after the children?"

"I know it is a bit silly, but I said my own goodbyes to the house the last time we were there, I don't want to go back again, you take Sarah and finish off," she said, softly.

"Well, I am sorry I upset you," I said giving her a final squeeze, "I'll go and call her and let her know it's ok."

"No need, I already told her you would" she said, a faint smile now crossing her face, "you're picking her up at 2:30 pm."

"Ah, so it's a 'fait accompli' anyway," I said, smiling back, glad to see she was recovering her normal demeanour.

That was how things happened between us sometimes, so I wasn't particularly surprised that it had been arranged between them already.

****************************************************************

The following afternoon, dressed in some old shorts and T shirt, I drove the few miles to Rob and Sarah's house, arriving at the appointed time and pulled onto their empty driveway. Sarah had obviously been waiting for me, as the front door opened, and she came out as I turned off the engine and got out of the car.

She was now in her early thirties, but looked younger than that in the tight, yellow, shorts and white, T shirt, top she was wearing. She had always kept her red hair at shoulder length and although she had more of a fuller figure than Jayne, they both kept in good shape with regular visits to the gym together.

She came to greet me, and as she came towards me, I became aware that she wasn't wearing a bra under her T shirt, as her breasts, which were always bigger than Jayne's, were moving freely under her top as she walked. I also noticed that the sun had brought out the freckles on her face and nose, which made her look even younger.

"Hi Pete," she said, giving me the usual hug and kiss on the cheek.

"Hi," I said back, putting my arms around her and feeling her unfettered breasts squash against my chest.

"The vacuum cleaner is by the door if you could just put it into the car," she said, pulling away, turning round, and starting to walk back towards the house, her light slip-on sandals slapping on the concrete.

I didn't move for moment, as I was busy taking in her shapely bottom in those tight little shorts. She obviously thought it was going to be hot again today and had dressed accordingly.

Our two families had been on holiday together several times, and last year she had worn the sexiest green bikini I had ever seen her wearing, that totally matched her green eyes. She had caught me staring one day and although she hadn't said anything, I knew she had caught me out by the little grin that had crossed her face before I could look away.

"Pete, I think you are staring again," she said, without even looking back.

Damn, these women must have eyes in the back of their heads I thought, as an involuntary blush coloured my face at being caught out again. I am sure she probably wouldn't have said anything if Rob had been around, even though it was just good-natured banter.

I collected the vacuum cleaner put it into the boot and then opened the passenger door for her to get in.

"Thank you, kind sir, I could get used to having a chauffeur open doors for me," she chuckled, as she slid into the seat pulling her long bare legs after her. I tried not to look too interested, but probably failed, although it appeared she hadn't noticed.

It was only about ten minutes later until she was sliding back out when we arrived at their old house. She stood and looked at it for a few moments, no doubt memories passing through her head from the times she had lived there.

"Are you ok?" I asked, lifting the vacuum cleaner from the car.

"Yes, I guess so, I was just thinking about some of the happy times I had here. Don't worry, lets get on with it shall we?"

She had the keys, so she led the way into the silent house.

"The carpet in the living room is staying, so could you just run the cleaner over it please Pete, while I go and look round all the rooms to make sure we have taken everything we want. The electricity is still on I think."

"Ok, no problem," I replied, "give me a shout if you need me for anything."

"Will do," she said, and made her way upstairs.

I plugged the cleaner in and started pushing it around the floor. It didn't take very long, so I did the dining area and the hall too, all in about fifteen minutes. I assumed the upstairs would need a quick go over, so I unplugged the cleaner ready to take it up there.

I hadn't seen Sarah since I started, and it all seemed eerily quiet as I made my way up the stairs.

I looked into a couple of the rooms and didn't see her in there, then I heard a slight noise and looking into Sarah's old bedroom, I found her sitting on the bed, absorbed in leafing through what looked like a photo album.

"Here you are," I said.

"Oh Pete, you made me jump," she said, a bit startled.

"Sorry, it was very quiet, and I wondered if you were ok."

"It's my fault, I found this dusty photo album lying flat on top of the wardrobe and I got distracted looking at these old photos."

"What are they?" I asked, moving into the room and siting down next to her, so I could see them.

"They are photos Jayne and I took ages ago that I had forgotten about. The album is very dusty so must have been lying flat on top there for a long time and been overlooked. I only noticed it because I stood on a chair to take these curtains down that Mom said she wanted."

"Oh wow," I said, "is that you playing with the dog?"

She giggled, "Yes, I must only have been about ten there, look at that terrible hair cut."

"Jayne too," I said, turning over a couple of pages, "goodness, she was very slim even then."

"We are a bit different for sisters, aren't we?"

"I suppose so, but you each have your good points."

"What do you think are mine then?" she asked, quickly, with a bit of a twinkle in her eyes.

"Ummmm, I don't think we should go down that route," I said, smiling, and aware of her bare leg against mine.

"Coward!" she said, laughing.

"Hmmm, maybe," I said, "safer that way though."

"I remember a time when you were a bit more adventurous than that though, in this very room in fact," she was grinning broadly now.

"That was a long time ago, lots of things have happened since." I said, feeling my cock stir just hearing her mentioning it after all this time.

"That's true," she paused, her finger drawing little circles on the dust cover on the mattress we were siting on, "but do you think about it ever?"

I wasn't sure where this was going. I thought that maybe the photos of years gone by had made her a bit nostalgic, as we had never mentioned this since it had happened.

"I have done," I answered, "now and then. Do you?"

"Sometimes, I do, yes."

"Is it a... good memory?" I asked, tentatively.

"Yes, of course," she said, softly, a faint blush creeping up from her neck. "Is it for you?"

"Yes, definitely," I responded, "although earlier that particular afternoon so long ago, when Jayne and I were on the sofa and you came quietly into the room, I nearly had a heart attack," I said, smiling at the thought now. "You were lucky that Jayne had no idea you were there."

She giggled, "That was a bit naughty, wasn't it, but I'd never seen anyone actually having sex before, it was very erotic. And anyway, if I hadn't, the rest wouldn't have happened, would it?" she added, looking straight into my eyes, her face flushed.

"No, I don't suppose it would," I replied, my cock hardening at the memory.

"Tell me though, I always wondered, what did make you come back that afternoon, after you dropped Jayne off at work?"

"Hmmm, I don't really know, I suppose I wanted to find out why you took such a risk, but you're right it was erotic. It is the first and only time anyone has watched me," I laughed, nervous at where this conversation might be leading.

There was silence for a few moments.

"So... ummm...when do you think about it?" she asked.

"What do you mean?"

"I mean, for example, do you ever think about it when you are, you know, alone and touching yourself?"

I thought the conversation was getting a bit strange, but it was sexy to be talking with Sarah about such intimate things after all this time.

"This conversation is getting a bit personal," I said, wondering what she was looking for.

She laughed, "You can't get much more personal than sitting on the same bed, with the same girl who you helped to lose her virginity, right here."

I had to admit she had a point.

"That's true enough," I said, joining in with her laughter.

"So, do you?" she persisted.

"I have done," I said, quietly, "that probably doesn't sound good, does it?"

She put her warm hand on my bare knee, "If it makes you feel any better, I have thought about what we did too sometimes, when I do it to myself."

"You mean when you masturbate?" I asked, surprised she would tell me what she thought about when she was fingering herself.

"Yes, well, we all do it, and we all think about something don't we?" she said, shyly, "but do you ever think about it when you're having sex with Jayne, and you know, think it's me perhaps?"

Now it's getting really weird," I said, not wanting to admit that I did.

"Go on, you can tell me, I'd like to know," she cajoled, rubbing her warm hand on my knee.

"I looked at her blushing face and neck and decided to be honest, "If you really want to know, yes, I have a few times," I said, feeling my own blush starting at telling her that. "What about you," I asked, curious to know now.

"As we are being truthful, when Rob and I have been making love, some of my best orgasms have been when I think about it," she admitted.

"Wow, that's an admission. I had no idea. I just thought you had forgotten all about it and wanted it that way." I said.

"I thought I did, but just occasionally it surfaces, and anyway, it seems to have created a bond and made us good friends, and we can still talk about anything, so that has to be good."

"That's true too."

"Do you ever wonder what it might be like now?"

"You mean...to have sex with you?"

She nodded.

My cock was rock hard and uncomfortable in my shorts. Fortunately, being old ones, they were a bit baggy, so I didn't think it showed.

"Well...if we are being honest, only as a fantasy. It's not something I have thought seriously about."

"Not even when I was wearing that green bikini last holiday?" she smirked.

She had me banged to rights. That was what I had thought about, banging her hard when I had seen her in it -- and she knew. This chat was getting sexier and more intimate by the minute. I tried to stop the blush I felt creeping into my face, but I couldn't.

"I think your face is giving me the answer," she said, knowingly.

"Yes, ok, you got me there," I said, as it was pointless to deny it now.

"Do you remember the conversation that started all of this way back then?"

"I do. It was all because my mate Dave had turned you down when you said you had 'offered it on a plate', if I remember correctly. Then you asked me what I would do if it was offered to me."

"And you said that you might be tempted if it were someone you fancied and you would if it was me. I remember that bit," she said.

"Yes, that's right, but I wasn't sure if you were playing some sort of testing game to see how I felt about Jayne."

"Testing game?"

"Yes, you know, get me to admit that I might have a 'wandering eye' given the opportunity, and then tell Jayne."

"Nooo," she laughed again, "it was nothing like that. I genuinely didn't understand why he turned me down, and I wanted to get the opinion of someone that I could trust, but perhaps it's better he did, otherwise we may not be sitting here right now," she said, absently rubbing her warm hand up and down my thigh.

"Hmm, there are a few truths coming out here," I said.

"Well, as we are exchanging truths, do you remember those weeks when I was asking various questions, and we did quite a few intimate things, right up to dry humping, but you said, 'no kissing', why was that?"

"Yes, I remember. It may sound a bit daft now, but by not kissing you, I felt that the things we did were just some sort of mechanical demonstration, and it helped to compartmentalise it, so that I didn't feel too guilty about your sister."

"But then, that afternoon when you came back, and we finally had sex, you broke your own rule, and we kissed a lot. It is another thing I wondered about," she said.

I hadn't realised she had held these questions in her head all this time, and now it seemed to me that with the house being sold and having new owners, it had prompted her to want some answers, to have some sort of closure was how I saw it. It was the first time we had ever discussed it since it happened those many years ago, and I thought it might probably be the last.

"To be honest, I didn't think we would ever actually have full sex, but that afternoon when you said you really wanted to try it, I knew it was a one-time only thing, and so I wanted it to be more making love than just cold sex, so that's why I felt I wanted to kiss you."

"Ohh, well I am glad you did; it did make it much better." she said, now drawing little circles with her fingernail on my thigh, "and is the 'no-kissing' rule back in operation," she added, almost bashfully.

"Well, we do kiss from time to time," I said.

"I know, but not properly, I mean...ummmm, would you... like to?"

"I think that might not go down too well with Rob or Jayne and result in some bodily injury to me," I said, trying to add bit of levity.

"They are not here now though are they, so there is no risk of that, is there?" she countered.

"We would know though, and I'm not sure we should complicate things," I said, my cock twitching again at the thought she might want to.

"I just thought, maybe, for old times sake, before all this has gone," she said, looking round the room.

A few kisses, I thought, wouldn't hurt, I was sure she would be totally discreet as she had been all these years and I certainly wasn't going to be the one to mention it to anyone.

"Do you really want to, I mean, this isn't some new 'test' is it?" I asked, with a grin.

"No, no test," she giggled, putting the photo album down onto the floor and turning to face me, "unless you are rubbish at kissing now of course."

I moved my face closer to hers.
She did the same.

Suddenly our lips were touching.

Her hand was still on my thigh but holding it now.

We kissed gently, our lips moving against each other.

My cock, still hard, twitched some more, and I could sense precum wetting my boxers under my shorts.

She was first to probe my lips with her tongue. When I felt it, I met hers with my own.

My hand went up behind her head into her red hair and pulled her closer.

Our tongues twisted and turned, then alternately ventured into each other's mouths; tasting, feeling, sucking sensuously.

Our noisy, accelerated breathing through our noses, echoed around the almost empty room.

I kissed round her mouth, over her cheek and onto her neck, sliding my tongue up and under one ear. Once more, just as before, she erupted in goosepimples and shivered. I remembered it was one of her sensitive spots.

She put her free hand behind my head and manoeuvred my mouth back to hers and we re-commenced with our tongues; touching, darting, each of us trying press our lips together harder. This was a different Sarah to the timid one I had lain here with that time before. She knew what she wanted.

Without letting go, she lifted her legs from the floor and slid part way across the narrow bed, pulling me with her. We ended up lying side by side, facing each other, still kissing, our bodies pressed together. I could feel my heart beating faster along with my breathing. I wondered how far this was going to go.

I still had one hand in the back of her hair, her head trapping my hand to the mattress. The other, I slid over her to the bottom of her T shirt where it had come untucked from her shorts and slid my hand underneath to caress her warm, bare, back. There was definitely no sign of a bra.

"Mmmmm," she said, into my mouth.

She copied me so that as we kissed, our hands wandered over the bare skin of each other's back, keeping us tightly together.

I could feel that my hard cock inside my shorts was pressed against her thigh, and I was sure she could feel it.

I still wasn't sure if she really did just want to do a bit of real kissing 'for old times sake' as she had put it, or perhaps more. My conscience about doing this with Jayne's sister, was gradually becoming eroded by the pleasure and excitement that Sarah was generating in me, and she seemed in no hurry to stop.

As I stroked her back, I couldn't resist moving my hand from the middle of her back to along her side, so that my fingers just rubbed the side of her breast. I knew that if that weren't what she wanted she would stop me, and I would know the boundaries. She didn't, and if anything, tried to kiss me harder.

Although I had seen the outline many times, I admit I wanted to feel what her breasts were like now after all this time, and after having two children. They had always been bigger than Jayne's, but I wanted to touch and re-acquaint myself with them.

I slid my hand further round, touching more and more each time, until I was holding one of her breasts in my hand, the hard nipple against my palm.

I pulled my face away from hers, "Is this ok," I asked, in a whisper.

She just nodded and then fixed her mouth back onto mine and put her tongue in my mouth.

I held it, stroked it, and massaged the nipple with my palm. I felt with my fingers the many bumps of her areola and teased the nipple that I am sure was thicker and harder than I remembered. As I alternately cupped her breast in my hand feeling the weight of it, certainly more than before, and ran my fingers over her sensitive nipples, I felt her move her leg over the top of mine so that her bare leg was resting over mine, pulling my hips harder towards her.

I could feel the heat of her body against me, with only our thin clothes separating us.

My conscience was still giving me the occasional poke, "Sarah," I whispered, breaking our kissing, (why do we always whisper in this situation?), "I love having you as a good friend, but I am not sure we should be doing this."

"You don't want to?"

"It's not that, it's just...well, as I said, we all have a good relationship, I would hate for all that to get ruined," I said, meaning it.

"I know what you are saying, but we have kept a secret for a long time, do you think we couldn't keep this one, or is it really that you don't find me sexy now I am older?"

"I do, you are sexy," I said, squeezing her nipple between my fingers.

"This is the last time all this; the house, my old room, this bed, will ever be here, I just wondered how it might feel, back here again." she said, almost wistfully.

I was lying there, her large breast in my hand, my hard cock twitching along her thigh, fighting with my thoughts and conscience, the later beginning to lose.

I think she could see my indecision, "We don't have to go all the way if it bothers you so much," she said, "we can stop whenever we want, but it is nice being here together for a while, isn't it?"

It was, I couldn't deny it, and I know you will think that if it was you dear reader, you might not have those qualms, but I knew we all had a lot to lose if it all went wrong for some reason.

"It is and I guess we can," I agreed, "either of us, at any time?"

"Of course, if we want to," she said, questioningly, and I knew now that she wouldn't be the one to stop us.

My conscience went quiet, and our faces closed together again, and we kissed, gently at first, her soft lips just nibbling on mine, she had certainly leaned a lot in the intervening years.

We quickly got back to the point we were at before, except that with her help in raising her body slightly, I lifted the bottom of her T shirt up until it was resting almost under her chin, and her breasts were on full display. I noticed that she still had those sexy freckles that came down from her neck and continued down, contrasting against her white skin on the top side of both breasts

I moved my head down away from hers and enveloped the nearest nipple in my mouth. It was definitely much bigger than I remembered; long, thick, and dark, despite her very fair complexion. She sighed as I sucked on it and forced it against my teeth firmly, but carefully. Her hand came to rest on my head, holding me to her breast like a sucking child.

"Oh, yes, Pete, that's really good," she whispered, "take your top off so I can feel your skin against me."

I let her nipple go, and with her tugging it, I manoeuvred the T shirt over my head. While we were in this position, I took the opportunity to slip hers off completely too. Now when we lay down, her naked breasts and hard nipples pressed against my bare chest. I kissed her again, pulling her towards me feeling those hard nubs pressing into my skin.

She ran her free hand over me, slid it between us and tweaked at my own nipple. It wasn't something Jayne ever did, but it felt electric, as though there was a direct connection to my penis that made it twitch. I wondered if women felt that same connection to their pussy when their nipples were pulled and teased or whether it was just the novelty of Sarah doing it.

Lying facing one another, my cock, still inside my shorts, it seated snugly in the slight gap of her thighs, the head pressed against where I guess her mound would be. Sarah pushed her hips forwards just fractionally, adjusting it exactly to where she wanted it to touch her.

"Pete," she said, moving her mouth away from mine, "do you remember how, when we were fully dressed that time, you showed me how you had sex with Jayne by pressing against me?"

"Yea, you had a huge orgasm if I remember correctly," I said, grinning, the image of it flashing through my brain.

"I did," she replied, and even started to blush, "I know now that what we did was dry-humping, but I didn't then. Would you...could we, try it again now, but with me lying down?" she asked, softly.

Hmm, I thought, lying on top of her and simulating sex wouldn't be having real sex, so that might solve the dilemma if we did dry-hump and I made her come, that might be good for both of us, if we both came, and we needn't go any further.

"You really want to?"

"You have been poking me with your erection since we laid down, so it would be just like before. I'd like to see if it feels the same."

I did think it would be fun and exciting, particularly as we were both naked from the waist up.

It didn't take much re-arrangement for me to gently push her onto her back and slide both of my legs over the nearest of hers, until I was lying between her legs, that she had opened wide to accommodate me. We both shuffled for a few moments until my cock was in the optimum position, pressing against where her clit would be under those little shorts.

"Mmmmm, that feels good Pete, I can feel you right up against me, it brings back a good memory," she said, "let's try moving together."

Keeping most of my weight on my elbows, I pressed my hips down and then slid up. I felt the friction on my cock, as she matched my movements, rubbing her cloth covered pussy against me.

Once we got into a gentle rhythm, it felt quite good. Not as good as real sex, but it was stimulating the right places for me, and judging by her sounds, for Sarah too. I bent my head and was able to latch onto one of her nipples, sucking and licking it in time with our movements. She put both hands on my bottom and held me against her as we writhed against one another.

I let her nipple slip from my mouth and transferred my mouth to hers. She accepted readily and pushed her tongue against mine turning her head to get maximum penetration. Leaning slightly to one side, I freed one hand and used my fingers to continue stroking her breast and teasing her nipple.

We were both breathing fast through our noses to gain as much air as possible in the increasingly hot room. I could see the beads of sweat on Sarah's forehead that matched the ones I could feel on my own.

"Pete," she said, breathlessly, "the friction of our shorts rubbing together is making me hot, could we do this in just our underwear do you think?"

She was right. Although what we were doing was sexy, it was becoming a bit uncomfortable, but to lose more clothes was getting closer to where I wasn't sure we should be going. I knew it would feel much better if we did, as my cock would be rubbing almost directly on her. My conscience twinged a little, but the thought of how better it would feel soon overcame it.

"Ummmm, ok, if you want to do that, I'm sure it will feel better," I said.

I moved just to the side of her and quickly undid my shorts, pushing them down and dropping them to the floor, then knelt by her side, wondering if she wanted me to remove her shorts or let her do it herself.

Sarah grinned when saw my cock tenting my boxers and attempting to push its way above the waistband.

"It's been a long time since I've seen that," she said, a gleam in her eyes, "could I see it properly?"

"I thought you just wanted to do what we were doing, but in our underwear?"

"I do...or did... but...I would love to see it again," she said, sitting up and moving closer to me.

It seemed a bit silly to refuse and anyway, although it was years ago, we had been here before. I didn't move as Sarah's hands slipped into each side of my waistband and carefully lowered it over my cock.

"God Pete, it looks thicker than I remember it, I can hardly believe it fitted that first time."

My cock was now dripping precum, and as I watched, Sarah put out her hand and pulled the foreskin down to expose the large dark head. I let out a sigh.

"Mmmm, I am so used to seeing Rob's, that I had forgotten you are not circumcised," she whispered, "and yours is much thicker."

"I wasn't sure I wanted to know that," I said, inwardly smiling.

The next thing I saw and felt, was Sarah's red hair and then warmth around the head of my cock, as she quickly bent her head and took it into her mouth.

"Oh fuck, Sarah, you didn't say you wanted to go this far." I said, in surprise at her action.

Taking her mouth off my cock and raising an eyebrow, she said, "You don't want me to then?"

She had me there. Who would say no to that?

"I...I just wasn't expecting you to," I said, feeling the warmth around the head return.

In the intervening years, it was clear that Sarah had had a lot of practice. She expertly swished her tongue around my cock, pushing the tip under the rim of the head and following it round as much as she could. She gradually took more of my cock into her mouth until I could feel it grazing the back of her throat giving me the most amazing sensations, then moving it in and out so that I was almost face-fucking her. All the time her red head of hair was bobbing in front of me.

Leaving my cock in her mouth and moving on it slowly, she massaged my balls, moving them around in the confines of their sack. One of her fingers slid behind my balls and massaged that sensitive bit of flesh between my testicles and anus. I knew that if she kept it up, I would be spewing my load down her throat fairly soon and I did wonder if that's what she was aiming for.

I think my groans of pleasure made her realise that too, and so slowly she pulled her mouth off from my cock with a final 'plop'.

"Oh God, where did you learn that?" I said, astonished.

She laughed, "I have had a bit more practice since our last time."

"I can tell, but that wasn't the dry-humping I expected," I said, grinning.

"You'll need to take my shorts off to do that though."

I started to pull my boxers back into place...

"You might as well leave them as they are, or better still, take them off," she said, seeing what I was doing.

"Are you sure?"

"I don't think it is going to matter now, do you?"

She had just been sucking my cock like an expert, so I had to agree with her and rather than leave them at half mast round my thighs, I slipped them off completely and dropped them onto the growing pile of clothes on the floor.

"Mmmm, I see you didn't take much persuading," she commented, mischievously, looking at my cock, wet from her ministrations, standing proud and erect.

"Your turn," I said, pointedly ignoring her comment, but instead reaching for the button and zipper of her shorts.

She helped me by lifting her bottom off the bed, enabling me to slide her shorts down her thighs and drop those too onto the floor. That left me totally naked and Sarah in just her thin, white, knickers, that I could see were partially see-thru from the wetness flowing from her pussy.

The perfume from her arousal assailed my nostrils as it had so many years ago, and I really wanted to taste her in case this was the only time.

I moved my legs back between hers, which she obediently opened to give me room.

Lowering my head, I let my nose touch the wetness of the material between her legs. The pungent perfume was much stronger close up and I couldn't wait to taste her with my tongue.

I know this sounds naive, as I was currently naked with my nearly naked sister-in-law, but I kept telling my conscience that I still thought that we could eventually only dry-hump without going all the way. I was therefore reluctant to remove her knickers completely with the temptation that would offer, so using a couple of fingers, I moved the thin material to one side, exposing two plump labia and neatly trimmed gingery-red pubic hair.

Memories flooded back of the first and last time I saw that view and what we did back then, serving to make me want to dive in there. This I did, sliding my tongue between those two wet pussy lips and delving into the depths.

She moaned and put her hand on my head, opening her legs more to give me better access. I licked from bottom to top and back again, carefully avoiding her clit that was larger than Jayne's, in fact only just smaller than the first joint of my little finger. As I did more of this, she kept manoeuvring her hips to try to get my tongue to make contact with that pink sensitive nub, that was already full extended from its hood. I teased her some more until I could hear the frustration building up in her sighs and moans and then took pity on her, flicking the end of her clit with the tip of my tongue.

She made the loudest noise then, that echoed around the room and once again I was glad the house didn't have any attached neighbours to hear. I knew what she wanted really, so putting my lips around her clit, I sucked, teased, moved it from side to side and generally gave it my full attention.

"Ohhhh yes, Pete...Oh my God, harder, harder," she hissed, through clenched teeth.

The way I was doing it was obviously what she needed, as it had certainly got Sarah's attention. She gripped my hair and held me in place, grinding her mound against my face to get maximum friction while continuing with her breathless moans and mumbled words.

She was so into it, that I thought she would soon come and maybe that was what she wanted, but no, she wasn't going to be short-changed. After several minutes of this, and I am sure a great deal of self-restraint, she used the hand in my hair to pull my head away from her, relaxing her hips to be flat on the bed.

"Are you ok, is something wrong?" I asked, surprised.

"No, nothing wrong, it's just that I am not ready for it to end just yet," she said, breathlessly.

"What do you mean?"

"It is not really going to be dry-humping now, but I want to feel your cock against me as you did that time, if you remember."

"I do remember," I said, "but I had a condom on then."

"Yes, it was the first time I had seen one and of course put one on," she giggled, "but we don't have to do that this time."

"We don't?"

"No, it's quite safe," she said, confidently.

"Just against you then," I confirmed.

"Yes, I want you to press it against me like you did before."

I remembered the feel of my cock sheathed in a Durex sliding between her bare pussy lips for the first time after she had taken off her knickers to make the sensations more pleasurable, but Sarah still had hers on now, and I was still worried that I would give in to temptation if we were both naked.

She must have sensed my hesitation.

"If it makes you feel more comfortable, I will leave these on," she said, indicating her thin underwear, "I am sure it will feel just as good."

"You really want to do this?"

"Yes, come on, it will be ok," she said. encouragingly.

My cock was ready, I was ready. I had this naked woman lying on the bed in front of me. I knew I probably shouldn't, but it is not a thing you can easily say no to, so carefully, I moved into position, with my legs outside hers and my cock sandwiched between her thighs against the wet crotch of her knickers, pressing hard against her swollen pussy lips.

"Mmmm, oh yes, that feels good Pete. Does it bring more memories back?" she asked, moving her hips fractionally up and down.

"Yes, vividly," I whispered, starting to move with her, feeling and knowing that my cock was rubbing against Jayne's sister's pussy again, even though there was some thin material between us.

I was sure that when our pubic bones touched, it was stimulating her clit, as each time, she tried to make the contact longer and harder.

Keeping most of my weight off her, I put my lips on hers and was rewarded by her tongue snaking out and pressing between my lips. I let it in and countered it with my own. Then as we moved our lower bodies against one another, we were back to sucking, licking and love making with our entwined tongues. The bed was squeaking on its old springs and our noisy breathing was once more echoing around the room.

"Ohhhh Pete, I thought about this more often than I said," she said, quickly and quietly, through our kissing mouths.

"Is that what the looks were about sometimes when we met with family?" I asked, using the fingers of one hand to pinch one of her nipples.
"You did notice then. Mmmm, Ohhh..."

"I wasn't sure what they meant and didn't want to make things difficult by saying anything," I said, moving my lips to nibble around her ear.

I loved that spot, as instantly, almost pre-programmed, the goose pimples appeared again, that sure was a sensitive spot for her.

My cock had been sliding in and out between her thighs against her knickers, as we kissed and talked, for about five minutes or so and although it felt good, it wasn't as good as against bare flesh.

"Sarah, I know what I said, but I think it would be better if I took your knickers off so that our skin is touching," I said, boldly.

"You are ok with that?"

"Yes, if you are," I said, looking into her eyes.

"Thing is...we have got really comfortable here though and we would both have to get up to do that," she whispered, sexily, running a hand down my back and massaging each naked buttock in turn.

"You don't want to then?" I said, a note of disappointment in my voice, as I thought she would have liked more intimate contact.

"No, well not exactly," she paused. "What I would like is for you to pull my knickers to one side and press the head of your cock against me there. I want to feel you right there."

That was unexpected, but I could see the lust in her eyes, and inside I knew where this was going, and felt powerless to stop it now, even if I had wanted to.

She knew exactly what to do, opening her legs for me as I swung first one leg and then the other in-between hers, to rest back against her, my cock now pressing against the soaking wet crotch of her knickers.

I reached down and hooked my finger into the narrow strip of material once more and pulled it sideways. It was so wet now that it stayed in place in the crease of her leg, exposing her swollen labia. I followed this by manoeuvring my hips to place the head of my cock just between her pussy lips.

When she felt it there, she sighed loudly.

"Mmmm, right there, that's it Pete."

Holding my cock, foreskin pulled right back, I slid it up and down that wet valley hitting her swollen clit at the top, to the accompaniment of more sighs and groans from Sarah.

She wiggled her bottom and pushed her hips up and to get the sensations she wanted.

"This is only the second time I have felt your bare cock against my pussy," she said, shuffling about a little more.

"And we shouldn't really be doing it," I replied, half-heartedly.

"I know, but I have thought about it so much over the years, I just wanted to feel you one last time, especially in here, before the house belongs to someone else," she whispered, a bit emotionally.

"It's ok," I said, "I get it."

"I thought you would, and you are the only one that could of course."

With that she wrapped her arms round me and pulled me closer against her, forcing her open lips against mine again in a lingering kiss that took my breath away.

When we came up for air, wrapped in each other arms, impulsively I asked, "Do you want to relive that a bit more and feel... I dunno, maybe just the tip of me inside you?"

"You would do that and not feel too guilty afterwards?" she asked.

"I think we might be past that point," I said.

"I'm sure we are, so yes, let me feel it again."

Having slid my cock up and down, covering the head in our mixed secretions, I had no trouble in lodging the head of my cock against her entrance and with a slight push forward, the head slipped inside her easily.

"I can feel you stretching me a bit Pete, but it is a much better feeling than the first time."

Despite having had two children the same as Jayne, she was still nicely tight and my cock-head felt snug in the warmth of her outer vagina as we just lay there soaking up the erotic sensations.

Sarah started to automatically move her hips, just a little, so that my cock-head moved in and out of her a small amount.

"That feels so good that it is making me want more Pete..."

I knew we were already technically fucking, and my conscience had totally deserted me now. It was so sexy, lying naked on top of Sarah; kissing, stroking, teasing, and now the head my of cock buried just inside her warm, female, tunnel.

"Are you asking to feel all of me inside you?" I whispered.

"Yes," she sort of hissed, "right inside me, all of you, please."

To be honest, I had got to the point where I wanted that too, and I wanted it soon, before I might inadvertently come due to all the visual, sensory, and erotic sensations I had been feeling during the time we had been in her old bedroom.

I lifted myself up slightly, and looked down at where we were joined, my dark pubic hair contrasting with her gingery-red trimmed bush, and very slowly pushed my hips forward, sinking further into Sarah. I relished the feeling and although it was difficult not to just ram it all the way in, I maintained a very slow penetration until there was no gap between us and only for the second time ever, our pubic bones bumped together with me completely filling her

I think Sarah must have been holding her breath, as when she felt me fully inside her, she let it out, sounding like a huge sigh of relief.

"Ohh, Sweet Jesus that takes me right back," she said, "it feels right somehow, even though I guess it's not really."

I don't know what I felt. It had been years, but lying between her legs and being fully inside her once again was almost like some sort of homecoming, but in a very sexy, erotic, way.

"You were always a sexy woman Sarah, but this...this is on another level," I said, sincerely.

"I think I will always feel close to you Pete, but this is a one-time thing, we still can't have a relationship, which would screw everything up. You know that don't you?"

"I didn't expect anything like this to happen, and I know its just a once only thing, so don't worry, we'll just look at it as an add-on to our secret," I replied.

"Yes, I think that's a good way to see it, but now I want you to move in me, if we can come together, it will make it perfect."

I didn't think there was more to say to that, so I began to slowly withdraw until we were back where we started, with only my cock-head inside her. Then all the way back inside, her pelvis copying my movements until I bottomed out as deep as I could.

We kissed more, she held me again to her so that our bodies were pressed against one another, just our hips free to move up and down, taking my cock to the very depths of her vagina and back out.

Both of us were listening and watching each other's noises and expressions to determine how far we were from our individual peaks, as we gradually increased the pace.

The old bed was squeaking about once every second to the rhythm of us fucking which, when added to the wet squelching sounds coming from her pussy, seemed to add yet another dimension to the sights and noises we were making.

"Ohhh yeaaa, deeper Pete, deeper..." she hissed at me.

I wanted to feel that too, and by now my pubic bone was hitting her clit hard with each stroke.

I felt her move her legs and then the feel of her heels on my bottom, pulling me as hard as she could towards her on every thrust I made. We were truly locked together in our ecstasy.

"Faster...faster," she gasped, her face a bright red and drops of sweat standing out on her forehead.

I was getting close and hot. I could feel the sweat on my back, and I was sure that the additional speed would tip me over the edge, but I wanted to make sure she was with me.

"I'm close Sarah, are you?" I asked, sucking in huge breaths.

"Yes, not far...not far," she managed.

I suddenly remembered to make sure, "Can I come in you, I mean it's ok?"

"Yes, you must, like that first time, I want you to."

Knowing that she wanted my sperm inside her was just that tiny thing that tripped the balance.

"Fuck, I'm coming." I groaned.

"Ahhhhggg, yes, me to, me too, fuck me Pete." she shouted.

I felt her trembling. Her body tightening like a spring. I felt the familiar movement of my fluids deep inside me that heralded my own climax starting. While we kept thrusting at one another, I felt the first burst of cum being pumped up my cock and then the sweet release as it sprayed onto Sarah's cervix deep inside her.

I knew she felt it, because simultaneously, she sort of shivered and then bucked her hips as if to swallow me entirely into her. Her muscles contracted and pulsed around my cock; her stomach spasmed against me, her muscles rippling from top to bottom.

"Fuck, oh fuck "she cried, "don't stop, don't stop," as she trembled and shook through the first part of her orgasm.

I could only see the bottom whites of her eyes as they seemed to be looking right up, or had rolled backwards in their sockets, her heels pulling hard against me, almost painfully, locking me to her.

I had no intention of stopping just yet as the second load of cum followed the first, and then a third. She must have been awash with it inside her as I could feel the quantity was far more than normal. The squelching noise increased in volume, and I could feel how wet we both were at the point my cock was still moving in and out of her.

"Oh my God, Oh my God," she started repeating, her breathing fast, "I think my heart is going to pop out of my chest."

As the last few smaller squirts of my cum landed inside her, and her internal muscles gradually stopped squeezing, I felt her heels on my bottom relax slowly and drop down to rest on the back of my calves.

She kissed me hard, not letting go of me with her arms.

I moved in and out of her very slowly and gently, savouring the last few little spasms and feeling hers in return.

"Stop Pete, please, I'm super-sensitive now," she said, "it always gets me like that when I have an earth-shattering climax like that."

"Wow, 'earth shattering' huh?"

"Yea, don't mock me and get big headed though, I told you earlier my best orgasms were when I thought about that first time, and now this, for real, was just amazing."

"Sorry, I'm not, I felt it too."

"Better than with my sister?" she asked, a slight grin on her face now.

"I'm not sure I should answer that, but if you must know, it was."

"Mmmm, that's nice to know, but don't worry I won't tell her," she chuckled.

I could feel my cock softening inside Sarah and as I moved to let it slide out, our combined cum and lubrication trickled out in a steady stream.

"Oh, look what we have done to the mattress," I said, looking down at the spreading dark stain between Sarah's legs.

"Don't worry," she said, sitting up to look, "we can just turn it over, it will be taken away tomorrow, so it won't matter."

She seemed to have all the answers.

"What about us, was it really a once only thing?" I asked.

"Well, that's what we said, but... you never know what the future might hold, I guess you will have to be content with the looks I give you for now," she said, a mischievous smile on her face.
My Girlfriend's Younger Sister Ch. 05
Sarah surprises me again...
All persons engaged in sexual activity in this story are over 18 years of age.

The first three chapters were based on a real event that happened in 1969 that is burned into my memory, when, bear in mind, there was no internet where anyone could readily obtain information as you can today. Only the detailed descriptions have been embellished to make a more readable story (my memory isn't that good). Reading these previous chapters may give you a better insight into the story background. These later stories are some years afterwards, and there is an element of cheating, as well as taboo in this story, so I have left it in the incest/taboo category (although no incest), for want of a better one. If you don't agree with the story elements, you don't have to read it, otherwise, enjoy.

Ch 5

My wife Jayne had just put the phone down from chatting with Sarah, her younger sister.

"Do you want to go to a party next Saturday Pete?" she asked, as she came back into the living room and sat beside me on the sofa, where I was watching the television.

"What sort of a party?" I asked.

"It's the birthday of Christine, one of Sarah's friends, I've met her a few times, so Sarah said we are invited too, if we want to go."

"Where is it going to be?"

"It's at Christine's house, but it's only a short walk from us, so we don't have to drive."

"What about the children though?" I asked, knowing we would have to find a babysitter.

"Well, if we want to go...," she began.

The way she said it, I guessed that she wanted to go and had already said 'yes', so some sort of arrangements had already been made, and asking me was just a polite formality.

"...Mom has agreed to stay at Sarah's and Rob's house to babysit their children and she would have ours there as well."

"Won't that be a bit much for her, four children to look after?"

"No, she says they always behave when it's just her and she loves having them all around her. Anyway, we won't be that far away if she needs us."

"How about Sarah and Rob, what are they going to do?"

"I said they could come and stay here for the night, so that Mom and the children don't get disturbed at whatever hour we get home."

"That sounds like a good idea."

I could see they had it all planned out, which wasn't unusual, as we were all fairly close and often helped each other out. Fortunately, neither Jayne nor Rob knew about how Sarah and I had 'helped each other out' at their Mom's old house a couple of months ago, when we cleared it all out to be sold, but that's in a previous story.

"It all sounds good then and we haven't been to a party for a long time. In fact, as we are not driving, we can both have a few drinks," I grinned, knowing that alcohol tended to increase Jayne's libido and she often became quite 'amorous' after a few glasses. Additionally, not having to worry about the children might make an enjoyable evening, I hoped.

Jayne smiled, "It will make a change, I'm looking forward to it," she said, happily, and gave me a peck on the lips before settling back to watch TV.

************************************************************

The following Saturday, after we had fed the children, we packed them into the car and took them round to Jayne's sister's house as arranged. They got on well with their cousins and were soon absorbed in playing together.

While Sarah and Rob went upstairs to get changed, Jayne had a short chat with her mom; gave her contact details and made sure she felt comfortable looking after all the children. She said she was fine and told us to have an enjoyable time and not to worry.

Eventually Sarah and Rob came back down.

I tried not to stare at Sarah as she had clearly made a huge effort.

She was wearing a daringly short, green, dress, with spaghetti straps, which had a plunging neckline that showed her curvaceous breasts to their best advantage. The green of the dress (not unlike the colour of the stunning bikini I had ogled over last year on holiday) complemented her red, curly, hair that she had brushed to a lustrous shine. She had matching green shoes with big stiletto heels that showed off her bare, tanned, shapely legs. Her immaculate makeup highlighted her bone structure, and the overall effect made her look at least six years younger, and very attractive.

As the weather was seasonably warm, Rob was dressed casually in light slacks and colourful, short-sleeved, shirt, but he was totally outshone by Sarah's outfit.

"Looks like I have some work to do when I get home if I am going to match that," Jayne said, "wow, you look great sis. I've not seen that dress before."

"No, I wanted to dress up for once and saw this in a shop in town, so I bought it on impulse."

"It was a good impulse," Jayne said, smiling, "what do you think Pete?"

"I err...think it really suits you," I said, lamely, not willing to say in front of everyone how sexy I found it.

"And you of course Rob," Jayne added, "looking good."

While Jayne focussed on including Rob in the conversation, I saw Sarah glance at me for just a fraction of a second and give me one of her looks. I twitched my eyebrows in acknowledgement that I thought I knew what she was thinking, but also knew that was as far as it could go tonight.

"Right, lets get back to our place," Jayne said, "so that we can get ready too."

We all trouped out to our car, Rob putting a small suitcase in the boot before gallantly helping Sarah into one of the back seats and then taking the other himself. It's only a few miles to our house and we were there fairly quickly.

I poured Rob and Sarah a glass of white wine and they made themselves comfortable in the living room while Jayne and I went upstairs to get changed.

"I wish I'd have found a dress like Sarah's," Jayne mused, quietly, as we got ready, "it's really sexy, isn't it?"

She said it in such a way that I knew I had to be careful and diplomatic, "I guess so, but that short black dress, with the sparkles on it, you've pick out to wear is going to make it look like you two ladies are models that have invaded the party. I hope you both don't outdo the birthday girl," I said, trying to attain the right level of complimentary enthusiasm.

"Ha ha," she laughed, slipping some tiny, black, lacy knickers up her long slim legs, "I doubt that."

I watched, my cock stirring as, without a bra, she slid a matching black camisole over her head, the bottom of it just reaching the top of her knickers. She didn't normally wear such sexy lingerie.

I was transfixed, my cock growing by the second as, next, she carefully pulled on a pair of self-supporting black stockings, a pair of black high heels, then stood up straight to look at herself in the full-length mirror.

She glanced over at me, "You're going to catch flies if your mouth stays open like that," she giggled.

I made a step to advance on her.

"Don't you dare," she said, still grinning at the effect she was having, "I didn't go to all this trouble to have it messed up -- well not just yet. Anyway, Sarah and Rob are just downstairs so you can put that thing away," she said, indicating with a head movement, my semi hard cock.

Disappointing as it was, I knew she was right, so with thoughts of what might happen later, I backed off while she slipped her dress on and I finished getting ready myself, dressing in a similar way to Rob.

We went downstairs to see that Rob and Sarah were relaxing on the sofa and on their second glass of white wine.

"Wow, you'd better save yourself for the party," Jayne said, "I am sure there will be lots to drink there."

"Just to get us in the mood," Rob said, finishing his glass before standing up.

"Are we ready to go?" Sarah asked, leaving her glass of wine almost untouched.

Both girls sensibly changed into some flat shoes and carried their 'heels' in a bag, for the ten-minute walk to the house where the party was being held. Rob and I also had a bag with some wine and beer as contributions to the event, and we set off.

It didn't take long to get there, and there was no mistaking which house it was, as we could hear the music from some distance away. I hoped that they had invited the neighbours!

We joined a few other couples jostling to get in and were soon inside amongst a large crowd of people that looked as though they might be partying well into the night. The only lights in the large open-plan room that we found ourselves in were what I thought were probably 'Christmas tree lights', strung around the walls, so it was quite dim.

All the furniture had been pushed against the walls and it looked like the carpet had sensibly been removed leaving a large area in the centre for dancing.

Christine, or 'Chris', came over to greet us, and after we had kissed, had a bit of 'small talk' and said all the ritual 'Happy Birthday', stuff, we were directed to the large kitchen and conservatory at the rear of the house, where there was a vast quantity of various drinks, sandwiches, pizzas, savoury snacks, etc. and told to just help ourselves.

"Looks like this is going to be fun," Rob shouted at me, over the music as we got ourselves beers, some drinks for our wives, and made our way back to the open area.

"Yea, it does," I replied, surreptitiously looking round at all the scantily clad ladies of all ages, who were already dancing in the open space.

It didn't take long for the two sisters to join in the dancing. They danced together, as they often did at the beginning of the evening, before Rob and I had built up enough courage with a few beers to lose our inhibitions and join them. So, we stood watching, sipping our beers and exchanging a few words with some of the other guys that we knew, who had the same idea.

The evening wore on, with more beers and several more drinks for Jayne and Sarah until eventually they managed to drag us onto the crowded dance area. Someone had switched off some of the brighter chains of lights leaving just the dim, twinkling, coloured ones, to provide a more discrete atmosphere where no one could really see what anyone else was doing.

I have to admit that I am not much of a dancer to some of the faster music, but I can shuffle around fairly successfully with the best of them when it comes to the slower numbers.

Whoever was putting on the music had calmed it down, playing smoochy songs, inducing people to cling to each other and sway together, some of whom had come as a couple and some who had just met.

Jayne and I were together, her arms round my neck and my hands on her bottom, pulling her tightly against me as we rotated slowly round to the beat of the music.

I could feel her bra-less small breasts and hard nipples pressing into my chest and her thighs moving against me through the thin dress she was wearing. I knew she could feel my cock, which had unsurprisingly become erect, pressing against her mound through our clothes. She had clearly had a drop more to drink that she was used to and was moving her body against me in a subtle, vertical, dry hump.

We kissed and she put her tongue in my mouth letting me taste a mixture of whatever she had been drinking. It wasn't unpleasant and I am sure she was tasting me in the same way.

"Mmmm, I cun feeeeel you're hard, right against my puuuusy," she said, into my ear, slurring her words.

Along with hearing her slurred words, I knew that she rarely used words like 'pussy', so I guessed it was the alcohol making her talk that way. It was arousing to hear her talking like that and it often led to uninhibited sex later where she would just let go, and I was hoping that was going to be the case.

Although I had drunk a few beers along with Rob, they hadn't affected me as much, and I thought it best if we sat down for a breather to let my erection go down and I could get Jayne a soft drink before she overdid it.

As it was so dim, I hadn't seen where Rob and Sarah were, but now it seemed they had the same idea as we ended up siting next to them. However, when I saw them, I realised that of the two of them, it was Rob who was the worse for wear and Sarah was holding her own.

"Is Rob ok?" I asked Sarah.

"Yea," she said, "as you know he normally only drinks a couple of beers, but for some reason he has had a few glasses of whisky too, and they weren't pub measures," she grinned.

"How about you?" I asked her.

"Oh, I'm ok, a bit 'merry', but at university I used to go out with a group on 'pub crawls', and I know it's probably not good, but I seem to be able to handle more than Rob these days," she grinned.

We sat there for a short while cooling off and trying to see who was dancing with who and where their hands were, but it was difficult to see much in the low light.

Suddenly, Jayne stood up, a bit steadier on her feet than before, "I want to dance again, come and dance with me Rob," she said, grabbing his hand and hauling him up. Without much choice, Rob somewhat reluctantly was pulled to the dance area with Jayne.

I watched them move into the shadows, cling to each other, and then they were lost in the rest of the people. We had danced with each other's partners before on holiday, so it wasn't anything new.

I looked at Sarah, "Well, looks like we should copy them," I said, taking her hand.

We followed them, and without thinking, I assumed the same hold as I had with my wife. Sarah didn't object and put her arms round my neck, resting her head on my shoulder, while I put both hands on her tight bottom.

As soon as I felt her larger breasts against my chest and her thighs against mine, well, talk about instant erection... I was hard again and pressing it against her, Sarah reacted by adjusting her position so that my cock was pressing against her mound, just as it had been with Jayne. I pulled her as tight as I could against me, not sure if I could feel, or was imagining that I could feel, the indentation of her pussy lips along my hard cock.

"That feels nice Pete," she purred, "and in public too."

There were a lot of couples doing the same thing, so I didn't feel we were 'on show' in any way, and made the most of it, grinding my body against her and feeling her reciprocal actions to the rhythm of the music.

I manoeuvred her into a relatively darker corner and having made sure I couldn't see Rob and Jayne, kissed her, slipping my tongue gently into her mouth and feeling her accept it and suck on it, then interweaving her tongue with mine. I knew we couldn't do much more, but it was very sexy and exciting, so we stayed that way during a number of songs.

As we rotated in the time-honoured way of 'slow dancing', I glanced around occasionally looking for Rob and Jayne, and on the last occasion, saw them in the dim light moving away from the dance area to sit down.

"Looks like Rob and Jayne have had enough," I said to Sarah, turning her so she could see them.

She giggled, "Ohh, poor Rob looks as though he has passed his limit," she said, "maybe we had better see how they are doing."

Reluctantly we separated and made our way over to them.

"What time is it?" Jayne asked sleepily when we reached them.

"Just after 1am," I told her.

"Oh God, I'm sorry but I think it's time we went home," she said, "I'm not used to this."

I looked at Sarah and she sort of shrugged 'ok'; I think we were all a bit tired by now but had had a fun time. I looked round to see if Chris was about so that we could say goodbye, but couldn't see her, so we decided to just leave, and Sarah would call her in the morning to say thank you.

I found Jayne's and Sarah's flat shoes which they changed into, Jayne more unsteadily than her sister and needing a bit of help, then we made our way out into the street. Jayne led, followed by Rob and when we got out there, we found it was much cooler than when we arrived.

"Brrrrr," Jayne said, "maybe I should have brought a coat."

Rob immediately put his arm round her shoulders, pulling her to him, "Sssss'ok, I'll keep you warm," he said, drunkenly, and they set off in the direction of home.

Seeing that Jayne had let him, I wasn't too bothered and did the same with Sarah.

The windows of all the houses we passed were dark, and it was very quiet. I had to keep shushing Rob and Jayne, who seemed to be laughing and talking very loudly about nothing in particular. It seemed to take longer to get back home than to get to the party, but eventually we made it and as Jayne couldn't get her key into the lock, I had to move them, still holding onto each other, away from the door so I could open it.

"I need a pee," Jayne announced, once we had all got inside, and steering a slightly crooked path, took herself off to the bathroom.

I only put the dim wall lights on in the living room, as it made it a bit cosier, and I didn't think anyone wanted the glare of the main lights in their eyes.

For some reason, Rob plonked himself down on the central cushion of the three-seater sofa and seeing this, Sarah chose to sit in one of the large comfy armchairs. I put on some soft, relaxing music and having asked around, I went into the kitchen to make some coffee for us all.

I heard Jayne come back down the stairs while I was putting the mugs of coffee on a tray and glimpsed her walking a bit unsteadily into the living room.

When I took the tray very carefully in there and placed it on the low table, I was surprised to see Jayne was sprawled sideways, a little untidily, her dress rucked up high on her thighs, on Rob's lap. I looked at Sarah to see her reaction, but she just shrugged, a hint of amusement on her face at her sister's and her husband's inebriated antics.

"Are you going to be ok like that?" I asked Jayne, a bit surprised at her unusual behaviour.

"Ohhhh yessss," she mumbled, "I'm sitting with my favourite brother-in-law."

"Thaaat's because I'm your only brother-in law," Rob slurred.

"Yeess, I know that, silly."

They both burst out laughing loudly at this very old joke, another sign of their drunken state.

"And I love you jusssst like a brother," Jayne added.

I gave Sarah her coffee and sat down in the other armchair with my own, wondering what the other two were going to amuse us with next.

They didn't touch their coffee, but Jayne gradually relaxed against him until her head was on his shoulder, her long legs drooping down to where her now shoeless feet touched the carpet with her eyes half closed. Rob had one arm round her waist stopping her from sliding off and the other resting on her stockinged knee.

Like Sarah, I wasn't very bothered by it as it was clear it was all alcohol fuelled.

From where I was sitting, I could see a long way up Jayne's short dress, past the top of her stockings to a flash of white thigh, and a small part of her lacy black knickers that I had watched her put on earlier, and I could feel my cock stirring at the sight.

Suddenly, Jayne opened her eyes, "You two look lonely over there," she said, "you should go and keep him company like Rob and me here," she managed, pointing roughly in Sarah's direction, "it's only fair."

I looked at Sarah who again gave a small shrug before getting up and coming over to sit on my lap, her back facing her husband and Jayne.

"That's better, now we are all the same," Jayne said, with a logic all her own, and lay back onto Rob's shoulder and closed her eyes.

When she sat down on me, I had done the same as Rob and could now feel the warmth of Sarah's body on my arm and hand, and her warm bottom resting directly on my cock, the closeness of which made my cock even more active. Knowing I couldn't be seen by the other couple, I began to slowly stroke Sarah's exposed inner thigh with my hand.

I was paying more attention to Sarah than Jayne, but out of the corner of my eye, I saw a slight movement and when I looked more closely, I could see that although they both had their eyes closed now, Rob's arm that was round her waist had moved upwards and his hand was slowly stroking the underside of Jayne's left breast. As I watched, I was sure his fingers were stretching upwards teasing her nipple too.
I wasn't sure whether to stop this now as nothing like this had happened before, but on the other hand it had never occurred to me that it was a bit of a turn on watching them. Anyway I reasoned, I had her sexy sister sitting on my lap, so it wasn't as if they were the only people who could do it, and I did have a secret history with Sarah.

"Don't move too quickly but have a look at what's happening over there," I whispered, almost inaudibly into Sarah's ear.

Slowly she turned her head and looked around at them.

She was grinning when she turned back, "I don't think it's going very far, they are both fairly wasted," she whispered.

"I know," I said, feeling my cock getting harder and becoming a bit more adventurous with my hand on Sarah's thigh, "does it bother you, what he is doing?"

"Not if you keep doing that to me," she said, as I continued to stroke up and down her leg.

I carried on watching, my cock now almost at full length.

"God, has it made you hard watching them?" Sarah whispered, "I can feel it under me."

"Not just them," I said, sliding my hand up to her neck and then down into the plunging neckline of her dress and onto her bra-covered breast. I easily found her nipple through the thin material and began to tease and roll it around with my fingers.

"Mmmm," she sighed.

I saw Jayne kiss the side of Rob's face and then he turned his head, and they were kissing lightly, oblivious to me watching.

Certain that Jayne and Rob were in their own alcohol induced world for now, I slid my hand up and then down inside her bra feeling her hard nipple across my palm.

"Do you like that?"

"Yesss, but they can't see can they," she said, with a hint of nervousness.

"Not with your back to them and I think they are too busy anyway," I replied, looking over at them again.

They were still kissing, although not ravishing each other with tongues, but as I watched I saw Rob move his other hand and slide it between Jayne's legs up her stockinged thigh, higher and higher, until one of Jayne's hands moved up and held onto his arm. It seemed that even in her current state, she wasn't going to let it go too far.

Having seen that, I wondered how far Sarah, whose breast I continued to stroke, would let me go, or wanted to go, with her husband and my wife just across the room.

With her sitting sideways on my lap, it was easy to kiss Sarah on the lips and she responded gently, slipping just the tip of her tongue against mine. I was very turned on by all that was happening and removing my hand from her firm, warm, globe, putting it back on the inside of her leg.

I stroked her thigh, moving further up each time until my fingers touched the flimsy material of her underwear. Unlike Jayne, she slowly opened her legs to give me better access, kissing me more passionately as I fingered her pussy through her knickers.

I moved my finger around, finding the indentation of her pussy lips through the material and slid it up and down, feeling the beginnings of dampness on the outside.

I stole another look at what was happening on the sofa and saw that they were still kissing, and Rob was once again trying move his hand up under Jayne's skirt. She stopped him again, but less forcefully I thought, and then to my astonishment, relaxed her hand on his arm and I saw it disappear upwards.

"I think Rob is going to finger your sister," I whispered.

"Really? Let me see," she said, with what I thought was a hint of excitement.

Once again, she slowly turned her head until she could see them. We both watched as it became clear what the movements under the small amount of dress still covering her legs meant. It was more or less obvious as Jayne opened her legs several inches, and we could just make out Rob's hand deep between her legs.

"I think he's got his finger in her." Sarah stated very quietly.

"I think so too," I said, my cock twitching under her.

"I can see his arm moving up and down now. God, I think he is finger fucking Jayne. Is it going too far? Do you want to put a stop to it?" she asked.

"I'm ok with it at the moment and I doubt they will remember in the morning. What about you?"

"I've never seen him be so bold before, and with my sister, but if it's not bothering you then I'm ok with it too. You could keep an eye on them though, but I wouldn't mind if you copied him," she said, sexily.

I didn't need a second hint and as my fingers were still touching her damp knickers, I hooked one round the narrow gusset and pulled it to one side. Sliding my middle finger between what were now wet pussy lips, I found her entrance easily and slipped it up into her vagina.

"Ohhhhh," she sighed, a bit too loud I thought despite the music that was still playing and probably loud enough to mask it.

"Shhh," I whispered, looking to see if there were any reactions from the two on the sofa, but saw no change.

Moving my hand, I inserted a second finger, and pushed them both inside Sarah as far as I could reach, until my palm was cupping her soft pubic hair. This elicited another sigh but thankfully much quieter.

She turned around and kissed me, pushing her tongue into my mouth, where we commenced twisting our tongues together, while trying not to make any noise.

Constrained by our position, she noiselessly dropped her outside foot onto the floor, which opened her legs a bit wider. Given that bit more freedom, I began to move my fingers in and out of her in earnest, curling my fingers to try to drag the tips over what I knew was her sensitive spot inside.

As I pleasured Sarah, I kept glancing over and realised that things had progressed. Rob had turned slightly to face her and although her eyes were still firmly closed, Jayne had opened her legs even wider and was gripping Rob's shoulder, her arm across his body. The back of her head was now resting on the back of the sofa, her throat exposed. I knew those signs.

"Have a look, I think Rob is going to make her come," I whispered to Sarah.

She turned her head again.

I slowly finger fucked Sarah, as together, we witnessed Jayne open her mouth soundlessly, then her body tremble two or three times, and then relax back into the sofa.

"Wow," Sarah said, "I think she just came, God, that's hot, I never thought I'd see Rob doing that to my sister, in a million years."

"Me neither," I said, a bit shocked, but also excited at seeing him get her off.

I was sure that in their drunken state, neither of them were aware of what was going on around them. It became more obvious when both Jayne and Rob, his hand still up her skirt but motionless, had relaxed back onto the sofa, and seemed to be going to sleep.

"Shall we wake them, and call it a night?" I suggested.

"Hmm, not just yet," Sarah said, a naughty gleam in her eye.

"I think they've drifted right off," I commented, hearing the faint sound of snoring from one of them.

"That's what happens when Rob has had too much to drink, he always falls into a dead sleep."

"Jayne too, funnily enough."

She looked over at them for a minute or so, then, very quietly, "Pete, you want to try something a bit daring?"

"Like what?"

"If I lift up a bit, can you unzip yourself?"

"Much as I'd like to, I don't think that's a good idea with our partners just over there."

"You can see they are flat out, and the music is still going, they won't hear," she insisted. "Come on, Rob's just had his fingers up inside your wife," she reminded me.

"Well, yea, I know, but what if I do, what then?"

"Do it and you'll see."

"You sure about this, if one of them opens their eyes..."

"Where's your sense of sexy adventure?" she challenged me.

Not wanting to appear to be a wimp, nervously, as she raised her bottom just enough, I unzipped my slacks.

"You have to take your cock out too; they can't see anything anyway as long as I am in the way."

I did as she said, and my painfully hard cock stood upright poking out of my slacks.

"Now just lift the back of my dress up but be quick this is making my legs ache."

I pulled her dress up at the back, exposing her light green, thin, knickers.

Dexterously, she simultaneously took hold of my cock, pulled her knickers to one side, and positioned it at her entrance, then slowly slid down all the way, engulfing my cock inside her.

"Oh fuck, Sarah," I hissed, "I didn't realise you were going to put my cock inside you with them over there, this is really risky."

"I know, but it is so hot isn't it, do you like it?" she whispered back, while flexing her internal muscles and squeezing my cock.

"Ohhh God, fuck, of course, this is so mad though."

"It's ok, now that I'm sitting back down, it would just look like I'm sitting on your lap. Only we know your cock is deep inside me," she grinned.

It was actually a big turn on, looking over at my wife and Sarah's husband while my cock was filling her vagina and twitching inside her.

I moved my hand round and slid it back under her dress until my fingers contacted my cock where it entered her. I moved my fingers round until I touched her clit which made her jump.

"Ohhhh, that's it," she gasped, "rub it gently."

There was plenty of moisture there now and using it as a lubricant, I began to slide my finger round and over the hard little nub of her clit.

After a couple of minutes of doing this, all the while keeping a wary eye on the sofa, I felt her move both elbows backwards onto the arm of the armchair. Then, using her feet and elbows as anchors, she slowly started to move her bottom up and down, just enough for my cock to slide a little way in and out of her.

"Ohhh fuck Sarah, that's incredible," I whispered.

"Keep doing what you're doing," she replied.

She couldn't move too much for fear of any noise or large movement disturbing our sleeping partners, but being so deep in her vagina, the friction was giving me amazing sensations. I tried to move my own hips too and with the softness of the cushion, was able to increase the variety of penetration a little more, at the same time as continuing to tease her sensitive clit.

God, I thought, I am fucking my wife's sister with Jayne just across the room, and Sarah's husband too. It had never crossed my mind that we would ever do this, but the danger of one of them perhaps waking up just amplified the excitement I was feeling from the sensations of my cock slowly moving in and out of her.

"Ohhh yes," Sarah hissed, when she felt my cock going deeper.

I tried to increase my movements, as I desperately wanted to get as deep as I could into Sarah, but the moment I did, the armchair started to make too much of a creaking noise with the two of us on it, so I had to go back to more gentle thrusting.

She was breathing much faster now and more noisily. I could feel not only the friction of her tight vaginal walls, but she was using her muscles to squeeze my cock in small spasms.

Suddenly, I saw Jayne's head move.

Sarah looked at me quizzically as I gripped her, pulling her down onto my lap so she couldn't move.

I signed to her by shifting my head to point at the sofa, flicking my eyes from side to side as I did so.

She caught on straight away and didn't move.

Being Sarah though, she couldn't resist squeezing my stationary cock deep inside her with those amazing muscles.

I shook my head 'no' at her, but it made no difference.

Jayne seemed only to be making herself more comfortable against Rob and thankfully never opened her eyes.

"I thought for a moment we might be in trouble there, but I think its ok," I whispered.

In response, Sarah simply re-started her movements.

I was already starting to feel the beginnings of my release deep down at the base of my cock, and by the way Sarah was making tiny sounds now, I was sure she wasn't far behind. The thought of coming inside Sarah in this situation just heightening the desire to get there.

With Sarah still moving frustratingly slowly up and down and my finger stimulating her sensitive button, I strained and pushed up my hips as much as I dared, to be as deep as I could.

I felt Sarah getting closer, her vagina was beginning to have involuntary little spasms around my cock, and I could see her hands flexing into tight knuckles, white against her green dress.

"Nearly there Pete, nearly there," she said, in a sort of hiss.

That was all I needed to finally trip my release as my sperm began its rapid ascent up my embedded cock and jet out, deep into Sarah.

I heard a louder groan, and she quickly kissed me hard, muffling her cry as she felt it flooding into her. Then her body was shaking, her legs trembling, and I could feel her whole body wanting to move in response to her climax, but with some willpower she controlled it to smaller movements obvious to me, but probably not too big to disturb our sleeping partners and attract attention.

My cock, meanwhile, having been stimulated several times during the evening, both by Jayne and Sarah, continued to pump the resulting full evening's cum against Sarah's cervix. Each pulse was another ecstatic pleasure bolt, enhanced by knowing how and where we were doing this.

Sarah's spasms slowly diminished, and she took in big lungful's of breath as though she had been holding it all this time.

"Oh my God, Pete, that was something else," she whispered, a naughty grin on her face, "I can't believe we actually did that right here."

"We must have been crazy," I replied, "but I haven't come like that for quite a while."

"You mean since the last time we did it together?" she said, grinning even more.

I just winked at her, but I think she knew.

As we slowly came back to reality, my rigid cock still plugging her tight vagina now full of our mixed cum, I suddenly realised we had to do something before my cock softened and let it all out.

"Sarah," I whispered urgently, "we are going to make a lot of mess in a moment, what can we do?"

"Oh, I wanted to feel you come in me, but I hadn't thought that far ahead," she said, breathlessly, "ummm... how about I suddenly get up and rush to the bathroom while you quickly zip up. Will that work?"

"It might wake them though when you stand up," I said, anxiously.

"As soon as I go, if they wake, just say something like 'we can't sleep down here all night' and they'll think we just woke them to go to bed."

I thought it would have to work as we had nothing to soak it up with and my cock was already starting to soften, I didn't think we had much choice or time left to think about it.

"OK, I'm going to rush to the bathroom now," she whispered, "are you ready?"

"I...I guess so," I said, uncertain if this would work.

"Here goes," she whispered.

She was lightening fast as she got up off me, my cock sliding out of her. She flipped her knickers back in place, not that there was much material there, but it seemed sufficient, as nothing seemed to be coming out of her as she shot across the room and out of the door.

I tried to quickly put my semi-hard cock back into my slacks and zip up, keeping an eye on the other two, but the saying 'more haste less speed' was never truer than at that moment. It wasn't as easy as I thought, but I eventually managed it without disturbing them. I looked carefully at the visible, slightly wet patch, where she had sat on me, but fortuitously, my slacks were dark, and I didn't think it showed too much in the dim light.

With a sigh of relief, I saw that Jayne and Rob were still asleep and Rob's hand had now dropped from under her skirt and was just laying, fingers up, on the sofa cushion.

Even though we had been fairly sure of what he had been doing, I don't know why, but I felt a sudden urge to confirm that he had in fact been fingering Jayne. Perhaps it was to partially ease a bit of guilty conscience, I don't know, but very slowly I got up from the chair and stealthily moved over towards the sofa.

I crouched down looking closely at Rob's open fingers, then carefully bent lower to smell them. Yes, there it was, the unmistakeable smell of a woman's juices.

Just then, Sarah came back into the room and saw me crouched down, "What are you doing?" she mouthed, silently.

Embarrassed at being caught-out, I got up slowly to give myself some time, but was unable to think of anything plausible, so blushing, I told her the truth.

"Really? You actually sniffed his fingers?" she said, incredulously, but an amused grin spreading across her face. "I never had you down as having a fetish like that," she added.

"No, I don't, I mean, I haven't," I blustered, "I... I emmm, just wanted to check."

"And had he?"

"Oh yes, definitely."

"How does that make you feel?" she asked, "I get the feeling it turned you on watching him fingering her?" her head slightly on one side, studying my reaction.

"Well, I suppose after what we just did, I can't say much can I. We guessed anyway that he had got Jayne off, so it wasn't anything I didn't know already." I said.

"Wow, I can see that thinking about it has made you hard again, hasn't it?" she said, spotting the growing lump in my slacks.

"I guess I can't deny the evidence," I said, blushing a bit deeper.

"I've found out something else about you tonight then, but I also didn't know he had it in him to do that either, but I'm sure the amount he had been drinking made him bolder. It's a pity he isn't that bold all the time," she said enigmatically.

It was my turn to grin, despite my embarrassing semi-erection.

"I think we had better wake them and get them to bed, don't you, it is getting late?" I said.

"Yea, I think you're right, but I might need a hand with Rob to get him up the stairs."

"Sure, lets start with him," I said, "give him a gentle shake."

With a little bit of persuasion, and some complaints, we managed to wake them both up sufficiently to get them up off the sofa. Jayne wanted a drink of water, so I took her into the kitchen and sat her down with a large glass full, and went to help Sarah with Rob.

I walked him unsteadily up the stairs and got him into the guest bedroom and onto the bed.

"Thanks Pete," Sarah said, "I can sort him out from here, I may just leave him as he is, as he is dozing off again already."

Sure enough he had turned on his side and was starting to snore.

"I'll just go and get Jayne and then we can all get some sleep."

Sarah stood by the open door to their room, "Ok, I'll wait here for a moment in case you need a hand, but she is not as big as Rob, so I'm sure you'll manage."

It took me a few minutes to get Jayne from the kitchen and persuade her to climb the stairs with me, as she kept pressing herself against me with her arms around my neck. She didn't drink much usually, but as predicted, she had lost a lot of her inhibitions and kept telling me how nice my body felt and how she 'wanted' me.

We got to where Sarah was standing just inside the door to their room, "Guudnight Siiisss," Jayne mumbled, as we passed by her.

A few steps more and we were at the door to our bedroom.

She held me closer and then putting her lips against my ear, whispered, sexily but very loudly, "You can do what you wanted to do earlier now, remember?"

I did remember, but wondered if she was in a fit state, and thought she might just fall asleep again as soon as she laid down on the bed.

I noticed Sarah hadn't gone inside and closed her door, but was still standing there, a pensive look on her face.

I manoeuvred Jayne into the bedroom, eventually getting her to let go of her arms around my neck and got her to lie on the bed.

"Aren't you going to ravish me," she slurred, "I know you like my underwear," she giggled.

Sarah meanwhile, had followed us and was watching from just outside our open door, out of Jayne's sight, and had heard what her sister was saying.

"Looks like she wants you to," she said, quietly, so that Jayne couldn't hear, "are you going to?" she smirked.
Despite our intimacy a little earlier, I was surprised by the her question.

"I'm not sure I should answer that, some things need to remain a bit private," I said, gently, but a bit embarrassed, "I could ask you the same thing?"

Sarah moved closer to me but still out of her sister's direct line of sight.

She put her mouth very close to my ear, "Well I won't be doing anything, because he's is out cold and anyway, I can still feel the wetness of your cum between my legs, so it wouldn't be a good idea would it?" she said, sexily.

"Err, no, I guess not," I replied, feeling my erection growing again on being reminded of what we had just done.

Jayne was on her back on the bed, her dress having ridden up displaying most of her thighs, and she was still making loud and lewd suggestions about what I should do to her. The combination of Sarah's words and Jayne's suggestive comments was getting me more aroused, but Sarah was still there and didn't seem in any hurry to leave.

"I'll see you tomorrow then," I said, intending to close the door after her.

"Pete," she suddenly whispered, hesitantly, "you know years ago, when Jayne was just your girlfriend and I asked all those questions of you?"

"Yes, of course," I said, nervously looking over to making sure Jayne wasn't taking any notice and wondering why she was bringing this up now.

"And you remember that time I sneaked downstairs when you and Jayne were having sex on the sofa and I stood and watched?"

"Yes," I said, "but why are you asking now?"

"It excited you didn't it, knowing I was watching?"

"Well, yes, it did, and I did admit it did at the time."

"It's the only time I have ever seen two people have sex in front of me."

"Ok, and I think you got excited at seeing us too, if I remember correctly?" I smiled at the memory from so long ago.

"I did, very much so, especially as it was my sister."

She paused, then, as if she was shy all over again and had built up the courage, she asked, "If you are going to fuck my sister now... emmmm... could I watch?"

"What? Do you mean stay here and watch us? Wow, that's a bit weird, isn't it, your own sister?"

"I know...," blushing now, "but it would be so sexy and she won't know, just like last time."

I was a bit taken aback that she wanted to watch, but I did remember that first and only time had excited me far more than I thought it would. However, now she was actively asking me rather than it being a spontaneous act, and I wasn't sure if it was something I should do.

"Pete, I am waiting for you, legs open, look," Jayne said, impatiently, from where she was laying.

"I really don't think this would be a good idea," I said, turning to Sarah.

"Aww, come on Pete, there probably won't be another opportunity, I'll be very quiet. Just imagine me watching as you put your hard cock into my sister, that you've just had in me, and I can see you're already hard," she said, in her sexiest voice yet, and reached forward to stroke my cock through my clothes.

She was right, I was rock hard, and I was wavering.

"You would be totally silent? She can't ever know," I said.

She could tell that I was thinking about it.

"Look, it'll just be one addition to our secrets, it will be fun. Now, go to Jayne before she starts wondering what you are doing, but leave the door half-open. I'll just go and slip into my bathrobe like before, and then sneak in quietly like I did that first time. I think we'll both find it exciting," she said, not waiting for a reply and heading quickly for her room.

Committed now, and a bit excited at the thought of her watching us, I half-closed the door as she had asked and quickly shed my clothes before I joined Jayne on the bed.

"There you are at last, I thought you had got lost on the way," she mumbled.

"No, I was just making sure Rob was ok and then taking my clothes off."

"Mmmmm you're naked and I need you," she said, pulling me to her.

"You've still got all your clothes on."

"Oh yes, so I have," she said, glancing down at herself, "you'd better at least take this dress off, eh?"

"Turn over and let me get the zip then; you may have to help a little."

With a bit of fumbling and moving her from front to back and side to side, I manged to slide her black dress over her head leaving her in her sexy black camisole, lacy knickers, and stockings. She looked very sexy laying there in only her thin underwear, just as she had when she was dressing for the party and wouldn't let me touch her.

She pulled me to lie on top of her, my cock resting on those black knickers.

"That's nice, I have been waiting for this," she said, "although I feel like we might have already done something, perhaps when we were dancing? I don't remember what, were you doing something to me with lots of people around you naughty man?" she giggled.

I realised she had an idea that something had happened earlier, and I knew it must have been when Rob was fingering her, but I just brushed if off by joining in with a short confirmatory laugh.

I ran both hands up, one either side of her head, through her hair, my hand partially covering her ears and then kissed her. I slipped my tongue into her mouth where she immediately reciprocated and began to passionately kiss me.

Although Jayne was fully focussed on me, I was partially listening for any indication that Sarah had come into the room. Sure enough as we kissed, I sort of felt another presence and then, probably because I was listening for it, the sound of very light footfall on the thick carpet. I was certain she was in the room and I experienced a wave of nervousness, wondering now why I had let her persuade me to let her watch.

I knew she couldn't blatantly stand and watch as Jayne would be sure to see her at some point, so I didn't know where she was or what she was going to do.

I continued to kiss my wife, then moved my hands down and over the thin camisole to cup each breast in turn and tease the already hard nipple of each with my finger and thumb. Jayne reacted with fervour and kissed me harder than ever, moaning into my mouth in a way she didn't normally do.

I went to put my hands under her top and onto her bare skin with a view to removing it completely, but she shook her head.

"Leave it on Pete, it's much sexier, I want you to fuck me with it on," she whispered.

That surprised me, as normally she liked us both to be naked, skin to skin, and she rarely asked me to 'fuck her' in that way; she really was in a heightened sexual mood tonight. I had a passing thought that she might actually welcome Sarah watching, perhaps finding it very erotic, but quickly dismissed the idea as being too far out for her, even floating on her present sexual cloud.

I did as she asked, stroking, teasing, and massaging her small breasts through the thin, silky, material. It seemed she was particularly sensitive and moaned and groaned in a manner she doesn't do all that often

"Ohh, I can feel your hard cock on my stomach," she said, "shall I suck it for you?"

Oh God, she didn't do that too often either, and at any other time I would have jumped at the chance, but I was worried that she might taste Sarah on it, also, if she moved or sat up, she might see her and that wouldn't be great.

"No, tonight is about you," I said, "let me make you feel good instead."

"Ohh, you are, you are," she hissed, breathing heavily.

I kissed down her neck, feeling her squirm as my tongue brushed her sensitive spots and then raised myself on one elbow and quickly glanced around.

I just caught a glimpse of Sarah's red hair as she was sitting on the carpet to one side of the bottom end of the bed. I felt more secure now that I knew where she was, as unless Jayne actually got up, she wouldn't be able to see her.

I slowly moved my mouth down Jayne's body, kissing the gap between her camisole and the top of her knickers from side to side, and using my hands to continue stimulating her nipples.

"Oh, that tickles," she said, giggling.

I heard a slight noise from where Sarah was sitting but it was quickly stifled.

I went lower, gradually sliding my whole body down the bed until my head was between her legs. As I slid down into that position, my legs gradually left the bed and my feet touched the floor.

Moving her flimsy knickers to one side, I began to lick her puffy pussy lips, already slick with her juices. I ran my tongue up and down, tasting her arousal and gratifyingly heard her moans and small noises growing in volume.

I had just moved my head to probe her entrance with my tongue when I felt something touch my cock that was now just hanging over the end of the bed. That 'something' then suddenly felt warm and wet and slowly enveloped my shaft.

I couldn't see, but could only feel what was happening. It didn't take too much imagination though to realise that Sarah had moved to sit with the back of her head against the bottom of the bed and my legs were either side of her. In that position, it had been easy for her to take my cock into her mouth. She was currently swirling her tongue round my sensitive glans giving me the most amazing sensations.

This was turning into a very kinky evening.

"Ohhh I love it when you do that," Jayne said, loudly, oblivious to her sister's presence and moving her hips as I sucked on her hard little clit.

The mouth on my cock started to move further up and down, taking it deeper each time, and a warm hand cupped my balls from behind, gently rolling them round. Sarah was being very bad, but it felt amazing, especially as there was little I could do about it.

I worked my tongue up and down Jayne's wet pussy, probing between the lips, teasing her entrance with the tip and then returning to stimulate her clit. I easily slid two of my fingers up into her as far as I could and felt her jerk when she felt the sudden intrusion.

"Yeeeeees, mmmm, Oh yesss Pete," she hissed, through gritted teeth, "fuck me with your fingers like you did earlier."

I knew she was referring to what Rob had done, but it seemed sensible to let her think otherwise.

Sarah meanwhile had removed my cock from her mouth and was now lazily letting her tongue slide around the sensitive head, probing under the edges of the helmet, and starting to drive me wild with the need to come.

I had to make sure I didn't come though, as even in her present state, Jayne might wonder what was happening if I presented her with a limp cock. So, reluctantly, I began to make my way back up the bed, until I was fully on top of Jayne again, taking my cock out of Sarah's reach.

Jayne looked at me with slightly out of focus eyes, "I want it now, inside me," she said.

I heard a small sigh form where Sarah was, but Jayne didn't seem to notice.

"Tell me what you want," I said, for Sarah's benefit, nuzzling her neck.

"I... want..."

"What?" I teased her.

"Alright then, I want your hard cock right up inside me as far as it will go and I want you to fill me with your cum," she said loudly, " is that clear enough?"

"Mmmm, I think I can do that, I answered.

I heard another just audible sigh from Sarah and sensed a bit of movement, I thought she might be fingering herself as she had that one time before.

I was now very worked up and trailing precum over Jayne's lacy knickers and stomach. I hoped that in her fully aroused state she would come quickly, as I knew that I wouldn't hold out long with all the stimulation I had, and was still having.

I moved down a little so that my cock was just touching the thin strip of material between her legs and reached down to position my cock in the right place. I could feel that her knickers had stayed pulled to one side, hooked over one of her puffy labia, and her entrance was invitingly bare and open for me.

"Ohhhhhhhh," I said, involuntarily, surprised to suddenly feel a hand, that could only be Sarah's, gripping my cock low down.

"Is something wrong?" Jayne said, raising her head slightly.

"No, no, it ...it just feels so sexy, with your underwear still on," I said, quickly, trying to hide my shock.

"Mmmm, I told you it would be," she replied, huskily, "ohhh yes, just there," she added, as I felt my cock being slid around Jayne's entrance.

I could now feel Sarah's bare arm touching the inside of my legs when she moved her hand, from where she was hidden at the bottom of the bed.

I had expected Sarah to just watch, not take part in any way, she really was pushing her involvement to the limit. Although I was worried she might give herself away, this was more erotic than anything I had done or even thought about before. It made me wonder how kinky Sarah really was and whether Rob knew about it.

The few seconds it had taken me to work out what was happening, Sarah had been manipulating the head of my cock around and between her sister's pussy lips, making sure her hand didn't actually touch her.

"Ooooo God, Pete, you're getting me close, doing that," Jayne mumbled.

I was trying to work out how to get Sarah to let go, in case Jayne felt an extra hand down there, when as if reading my thoughts, Sarah stopped moving my cock around and located the head of my cock at Jayne's sopping entrance. With a slight push, she sent the head into her sisters vagina.

As soon as I realised the head of my cock had penetrated her, I slid forwards burying my cock into her until our pubic hair touched and my balls rested against her bottom.

"Oh my God, yes, at last," Jayne said.

I heard a quiet outlet of breath from the bottom of the bed.

As I began to slowly move in and out of Jayne, her hips beginning to match mine, I realised Sarah wasn't finished yet. Making sure she was only touching me, I felt her hand gently grip my balls, pushing and pulling them in time to our fucking.

Knowing that Sarah was actively helping me to fuck her sister, and probably had a ringside view of my cock plunging in and out of Jayne's vagina, was indescribably erotic.

Jayne was now actively moving her hips in synchronism with me, as usual timing her movement to coincide with my thrust, so that my cock went as deep as it could into her.

This 'secret threesome', without Jayne's knowledge, was giving me some pangs of guilt, but as each negative thought developed, it was quickly subdued and overridden by whatever hormones and chemicals had been released into my body by the excitement and eroticism of the situation.

The sensations were about to get even more overwhelming as, with the palm of her hand against the bottom of my balls, I felt one of Sarah's fingers, wet with the lubrication seeping down my cock, gently start to probe my anus.

As I fucked Jayne, her moans and entreaties to 'go deeper and harder' getting louder, Sarah too pushed harder and slipped one long finger inside me.

The moment she got it all the way in and then pressed downwards, sent me over the top.

I felt the pressure at the base of my cock increase as my cum began its rapid ascent. Within less than a second the first rope of semen splashed inside Jayne's pulsing vagina. She knew from experience when I was about to come, and as she too had been on the edge, the feeling she experienced when I began my ejaculation triggered her release too.

Having come only recently inside Sarah, there wasn't a lot of sperm, but it didn't stop my cock pulsing as my body tried to eject whatever was still stored into this waiting, warm, receptacle.

"Ohhhh yes, fuck, don't stop, don't stop," Jayne moaned out loud, bucking her hips upwards as her orgasm hit her.

Fortunately, the sound of the bed protesting at the movements, and her loud noise, drowned out the muffled sound I heard of Sarah also coming, and at the same time I felt Sarah's finger being removed from my anus. I couldn't see what she had been doing, but I assumed she had fingered herself to a climax fuelled by the sight and sounds of her sister being fucked, and by the risky things she had been doing to me.

I lay with my cock still deep inside Jayne while she enjoyed the small aftershocks that always followed her orgasms until gradually she became still, her eyes still closed, but a satisfied look on her face.

"Oh wow, Pete, that was worth the wait," Jayne said, still not moving.

"Mmmmm," I agreed.

As my cock began to soften, I realised that somehow Sarah had to get out of the bedroom without Jayne suspecting she had been there all the time. Hoping that she would take the hint, I moved my body and my head up a little more and kissed Jayne. Then as I had before, I put both hands on the sides of her face in a loving gesture, but partially covering her ears.

I heard a slight shuffling noise on the carpet, and had to force myself not to laugh when I heard what I thought was Sarah's knee 'crack' as she moved.

We kissed for another minute or so until I felt my cock slide out of my wife, then quickly kneeling up, I chanced a quick look round to make sure Sarah had left for her own room.

"I need the bathroom," Jayne said, slowly sitting up. "Oh God!" she exclaimed, her eyes opening wide and putting her hand over her mouth.

"What?" I said, feeling a sudden dread that Sarah hadn't actually left or she had just glimpsed her leaving.

"We left the door open," she said, "Sarah and Rob might have heard us."

"They are probably asleep, I don't think we should worry about that," I said, breathing a sigh of relief and inwardly smiling.
My Girlfriend's Younger Sister Ch. 06
A leak, and a surprise game, makes life interesting.
All persons engaged in sexual activity in this story are over 18 years of age.

The first three chapters were based on a real event that happened in 1969, that is burned into my memory, when, bear in mind, there was no internet where anyone could readily obtain information as you can today. Only the detailed descriptions have been embellished to make a more readable story (my memory isn't that good).

Reading these previous chapters may give you a better insight into the story background, as time has now moved on a considerable number of years.

There is an element of cheating and swapping in this story, so if you don't agree with that, you don't have to read it, otherwise, enjoy.

Ch 6

It was another very warm day, about three weeks after Jayne and I, accompanied by her sister Sarah and Rob, had been to 'that' party. When we had returned home, both my wife and Sarah's husband had been very inebriated.

That evening had evolved into spontaneous and unexpected sexual activities that only Sarah and I remembered, which we had agreed to add to our small list of 'secrets' that we held between us and is detailed in the last chapter.

I was sitting out in the garden in just a T shirt and shorts, with a morning cup of coffee and reading a newspaper, while enjoying the warmth of the sun.

"Sarah's got a problem," my wife said, coming out into the garden, having just come off the phone with her sister.

"What sort of problem?" I asked, my guilty conscience already making up bad scenarios.

"There's water dripping from under the basin in the bathroom and Rob is away until Monday at some conference up north."

"Can't she just put a bucket under it for now," I said, relieved but aware that her problem could soon become mine.

"She has of course," Jayne said, a little testily, "but she is worried that it might get worse and flood the bathroom."

"How about a plumber?"

"It's Saturday isn't it, not only would it cost a fortune to get an emergency call-out at a weekend, but I doubt we could even find one available," Jayne said.

I noticed the change now to 'we'.

I knew where this was going, and as I am a practical guy and had done lots of plumbing work in our own home, and we were family after all, I thought I would earn a few 'brownie points' by volunteering before Jayne asked me to.

"So, do you want me to go round there and see if I can do something?" I asked, standing up slowly.

"Oh, would you, that would be the nice thing to do and perhaps I might reward you later," she said, coming over and hugging me, pressing herself against me.

I reciprocated by putting my arms round her, my hands on her firm bottom and pulling her closer towards me. My cock immediately reacted.

"Oh no," she said gently, beginning to push me away with a twinkle in her eye, "after, not before."

"Hmmm," I said, as I reluctantly released her.

"I tell you what, it's such a nice day, I'll and come with you and bring the children, then I can look after their cousins too so that they are not under your feet while you see if you can sort something out for Sarah."

"That sounds like a plan, perhaps you can take them all to the park just down the road, they can let off some steam, so they are tired later," I said, winking at her.

"Yes, maybe," she chuckled.

"How about you ring your sister back while I go and find some tools and bits and pieces that I might need."

"OK, and thank you," she said, returning to the house.

I wandered off to the garage and filled my toolbox with everything I thought I might need, not sure what might be at Sarah and Rob's house. I knew he wasn't much of a 'do-it-yourself' man, and probably hadn't got much in the way of plumbing tools or spare bits and pieces.

By the time I had done that, Jayne had the children ready, who were excited at the unexpected visit to see their cousins. Being a warm day, none of us were wearing many clothes, mostly T shirts of assorted colours, and shorts.

Jayne looked good in her mid-thigh denim shorts, with her long legs, tanned from often being out in the sun. After having two children each, the two sisters still visit the gym regularly together, keeping their bodies in trim. As I have mentioned in previous chapters, Jayne has a slim figure, with smaller breasts than red-haired Sarah, who has fuller figure, but both of them look fit and several years younger than their actual age.

It didn't take long to drive to Sarah's, and as we pulled onto the drive, she opened the door of the house and our two children were quickly out of the car to go and see their cousins, leaving us adults to get out with a little more decorum.

"Hi Sarah," I said, giving her the usual kiss on her cheek, followed by Jayne doing the same.

"Thanks for coming over," she said, looking a little worried.

"It's no problem," I said, casting my eyes over Sarah's skimpy tight top and short flowery skirt. It was clear she hadn't bothered with a bra as I could see the soft outline of her nipples under the top.

"We've made it into a little outing for the children, and I'll keep an eye on them all while Pete sees what he can do," Jayne said.

"Oh that's great," Sarah replied.

Sarah rarely missed anything and had seen me eying her up and gave a small enigmatic smile before inviting us into the house.

"So, what's the problem?" I asked, once inside.

"It'll be easier if you come and take a look, it's a leak of some sort under the basin in our en-suite bathroom."

"Go and have a look, then come and tell me what you think," Jane said, "I'll take the children out into the garden."

"Right, lead on, Sarah," although from the many previous visits, I knew where it was, but I had never been into their bedroom before and it felt like a personal space I needed to be invited into.

Sarah went up the stairs with me following. The higher she got, the more of her thighs I could see under that short, loose, skirt. I slowed down and let her get another step ahead of me and it was then I caught a flash of white lacy knickers, hugging her bottom. At that moment, she turned and glanced back...damn, caught again.

"Incorrigible," she said, quietly, with a grin, and continued up the stairs to the first-floor landing.

She led the way into their bedroom, all neat and tidy as if no one ever used the room, then into the attached bathroom.

"It's under here," she said, crouching down and pointing through the doors of a small floor-standing cupboard with a basin inset into the top.

I was tempted to get another eyeful as her skirt had ridden up her thighs, but having just been caught I decided to concentrate on the problem.

I could see she had indeed put a small bucket under the leak, and it was slowly being filled by a constant heavy drip of water.

"I'll have to go and get a torch so I can see what's going on," I said.

"I've got one here I was using, but it's very awkward to see under there."

As with most of these units, you have to squeeze in on your back to be able to look upwards under the basin at the connections to the tap. I moved the bucket out of the way and prepared to get wet as I didn't want to turn the water off at the mains until I had seen where the leak was coming from.

I took the torch off her and lying down on the floor, slid my shoulders into the base of the unit. As I expected I started to feel the drip of chilly water on my chest.

"Sorry, you're going to get very wet," Sarah said, crouching down to look into the unit.

With her knees pointing towards me, it was very distracting, as now I had a clear view right up her skirt to the lacy white knickers I had glimpsed earlier. However, the constant drip of water on me focussed my attention on seeing where the water was coming from before I drowned.

"Ahh, I can see it," I said.

Sarah giggled.

"It's the flexible pipe connected to the tap that's leaking," I said, ignoring Sarah's laugh at the interpreted inuendo.

I realised that she knew exactly what she was doing crouched down there.

With a bit of effort, I struggled back out, forcing Sarah to move out of the way.

"Oh goodness, your T shirt is soaked," she said, stating the obvious.

"Yes, it's a good job it's a hot day and not winter," I replied, "I'd better go and turn the water off now that I know what the cause is."

"Can you fix it?"

"Yes, I think so, but it's a bit tricky, I'll go and get a few things from the car once the water is off," I said, "can you put the bucket back for now."

Having found the stop-tap in the kitchen, I went out to see Jayne who was happily sitting in the sun in the garden watching the children playing together.

"Good Lord, you look as though you have been bathing with your clothes on," she said, grinning.

"Yes, it's a wet T shirt contest," I quipped, "it's you and Sarah's turn next."

"In your dreams," she laughed.

"This is going to take a while, probably about and hour or so, do you want to stop here or take the children to the park?"

"Oh, if it's going to be that long we'll walk down to the park and come back later," she said, getting up and preparing to gather the children together, "oh, and you might want to take that shirt off and put it on the washing line here to dry in the sun," she added.

I did as she said and then went out to the car to get the tools and a new flexible pipe, which I had brought just in case, that I hoped would fit.

As I went back to the house, I passed her with the children, carrying some balls and a couple of tennis racquets heading for the local park.

"Have fun," I said.

"You too," she responded, laughing.

'I doubt it', I thought.

Sarah was still where I left her, but the water had now stopped dripping.

"Oh, I like the new look," she said, seeing my bare upper half and quickly running her hand through my chest hair.

"Errr, lets not start anything," I said, removing her hand, "Jayne suggested I hang my shirt out to dry, and she has taken all the children down to the park for an hour or so, while I sort this out," I said.

She looked thoughtful and had a strange look on her face, "So, it's just you and me here now?"

"Yes, I guess so," I said, removing the bucket and then lying down to get back under the basin, to change the pipe.

"Can you pass me that long spanner thing and the new pipe please," I asked her once I was in position.

She again crouched down to pass them to me, giving me another show.

"Right, now can you hold onto the tap while I unscrew the old pipe, please?"

There was a pause as she stood up, then, "Ok, I'm doing it," she said, and had put her feet either side of me at the level of my hips. Now I had an even better view up her skirt as she had her legs apart.

I thought, 'this is going to take much longer with this distraction' but began to carefully unscrew the old pipe.

"Pete..."

"What?"

"I have wanted to ask something."

"Ok?" I grunted, as I struggled with the awkward connections.

"I was wondering... whether Jayne ever said anything about the night of the party, you know, when we did a few things afterwards?"

"Umm...no, I don't think she remembered much about it. Why?"

"You know me, I was curious to know if she had remembered any of it."

"No, why, did Rob say something?"

"Oh no, he hardly remembers going to the party, he was so drunk," she chuckled.

"Oh good, that's a relief," I said.

"It was fun though, wasn't it?"

"Yes, but a bit risky though."

"That makes it more exciting, doesn't it?"

"Maybe," I said, "but we were also a bit drunk too, otherwise it probably wouldn't have happened."

I was wondering where this conversation was going.

"I mean, seeing, hearing and feeling you having sex with Jayne that night without her knowing was really sexy, I keep thinking about it," she continued, along the same line.

Remembering that she had surreptitiously sucked my cock while I was eating out a drunken Jayne, and then actively helped to push my cock into Jayne, without her knowing, had my cock growing in my shorts at the memory.

"Well, I didn't know you were going to do that, I thought you just wanted to watch like that first time."

"I was, but then I saw the opportunity and just went for it," she chuckled again.

"It was a bit of a shock and a bit naughty," the memory stirring my cock even more.

"But I can see by the reaction in your shorts now, that you liked it, and you're thinking about it."

"I admit it was very erotic, but I think you're taking too many chances and..."

Although she still had hold of the tap on top of the basin, as I tried to get the spanner into the constricted space underneath to undo it, I glimpsed and felt her knees coming down to the floor so that she was kneeling with her legs either side of me.

"What are you doing?"

I soon discovered, as she lowered her body so that her clothed pussy landed right on what was now an almost full erection.

"Mmmm," she purred.

"No Sarah, we can't, Jayne will be back soon, and I won't be able to fix this if you do that, and you'll have no water."

"I'm sure you can multi-task," she said, sliding slightly back and forth.

My cock thought it was a great idea as it was now fully hard, but my back and shoulders were beginning to hurt from the position I was in.

"Sarah, you really need to let me finish this," I said, more sternly.

"Hmmm, ok then spoilsport," she said, slightly grumpily, and stood back up.

After about twenty minutes and with a bit more twisting and turning in the confined space, I eventually managed to replace the pipe. After checking, with the water back on again, that all was well, I went back upstairs and began to pack away my tools in the bathroom.

"Thank you," Sarah said, "it's a relief to know I am not going to wake up to a flooded bathroom and besides, I am sure you have saved me a lot of money."

"No problem, I'm glad it was something relatively simple." I said, lifting my shoulders up and down to ease some of the pain and tension in my muscles.

"Have you hurt your back?"

"No, it's just cramped a bit from laying under there for so long."

"Turn around, let me see if I can free them a bit."

"No. it's fine, it'll be ok in a minute or two."

"Just do it," she said, probably like she would to one of her children.

With a huff, I did as I was told and felt Sarah's fingers begin probing my taut shoulder muscles.

"Oww, that's sore," I yelped, as she dug her fingers in harder.

"I hardly touched you. Come and lie down on the bed for a moment and I'll have a proper go at loosening them."

"Hmm, ok, but not too rough," I said, heading into their bedroom and laying face down on the bed.

"Don't be such a baby, no pain no gain," she said, unsympathetically, as she followed me and got onto the bed, sitting herself astride my bottom.

I could feel her warmth on me as she leaned forwards and began to manipulate my shoulder and neck muscles with long sweeps of her hands.

"We could have done with some massage oil, but you'll have to put up with just my hands for now."

"That's ok, what you're doing is just fine." I said, beginning to feel my muscles respond as she gradually pressed her fingers in harder, searching out the knots in them.

As the tension diminished, I began to feel other sensations from her warm thighs either side of me, and whatever part of her that was rubbing along my bottom as she moved. Knowing she only had on a short, thin, skirt, I surmised that her knickers must be directly against my shorts. My cock responded to the thoughts by beginning to grow again.

After about 10 minutes of this, with my cock now fully erect under me, I felt my back beginning to get sore from the friction of her hands and fingers directly on my skin.

"I think that will do for now, my back is getting a bit sore."

"Well, you'd better turn over then, I need to release the tension along the top of the front of your shoulders," she replied, lifting herself up onto her knees.

"It's ok," I said, aware of the state of my cock, "I think I'll be fine now, thanks."

"Are you being a baby again, just turn over for goodness sake," she insisted, in that mother-like voice.

'Oh well', I thought, 'it won't be the first time today she has felt it ', so I turned over to lie on my back, looking up at her.

She plonked herself down, right onto the length of my cock.

"Ohhh, I see," she grinned.

"Yes, sorry," I said, a bit embarrassed.

"Oh, don't be," she said, her eyes sparkling, and experimentally she slid up and down a few inches.

"You know what, I think you deserve a reward," she said quietly, rubbing her hand over my bare chest and pinching a nipple on the way.

Jayne had already promised me a 'reward' and with Sarah in this mood, I had a good idea what she had in mind.

"This is not a good idea, we don't want to do anything that might jeopardise both our families, do we?"

"No, of course not, but we do share a special bond, and a few secrets don't we, and although it was a long time ago, I often remember the things we did, and that you were my first," she said, somewhat wistfully. "I told you before, I sometimes think of those times when I'm with Rob and it always makes me come much harder."

"I know you did, and I told you I do too. You are an attractive woman, but Jayne will be back soon with the children."

"Would there be time for just a 'thank you' kiss then," she whispered, sexily, pressing her mound down hard against me and looking at me with those green eyes of hers.

I was nervous about the time, but she had got me excited, and I could smell and feel the warmth of her body against me. My cock twitched. I thought that even a long kiss wouldn't take too long, and from previous experiences, I did enjoy the way she kissed. I was rapidly losing my resolve.

It may sound odd, but I did feel a bit awkward being like this in the private space of their bedroom. However, Sarah didn't seem to have such qualms and quickly moved her head down towards me so that her lips were close enough for me to feel her warm breath on my face and her covered breasts touching my bare chest.

"Thank you," she said, quietly, before closing the gap between her lips and mine.

I said she was a good kisser, and within seconds, her tongue was probing past my lips into my mouth while in turn, I automatically put my arms around her.

As our tongues began to explore each other, I held onto her more tightly and I could feel my cock pressing against her through her thin knickers.

She shuffled her hips around until she managed to position my cock where she wanted it, in the 'V' of her thighs.

She broke our kiss to take a breath, "This brings back memories, feeling you against me like this," she whispered.

"Lots of other things have happened since then though."

"I know, but it all comes back to when we did this," she said, sensually grinding her body against me.

"I know, and it seemed harmless, but look what happened afterwards."

"You don't regret it, do you?" she asked, with a hint of seriousness.

"Does this feel like I did," I responded, copying her actions so that my hard cock moved against her in time with her own movements.

"Mmmm, no, I guess not, it feels really good, doesn't it?"

I had to admit that through our thin clothes, I could feel the head of my cock sliding against the soft part of where I knew her pussy would be, and it felt very sexy to be sort of dry-humping her in this way.

When I looked down, I could see that her nipples, erect now with her obvious arousal were tenting her tight top and just asking to be touched.

My excitement was such that without thinking any further than the next minute, I raised my left hand and placed it over her left breast and began a gentle massage, catching the hard nipple with the palm of my hand as I moved it around her medium sized breast.
"Mmmm," Sarah sighed, "that's nice too," and then locked her lips back onto mine.

I hadn't intended that this should go much further than a few kisses, but finding myself lying under Sarah, between her legs, was making the temptation almost irresistible.

"I... think we should go downstairs in case Jayne comes back," I suggested, unconvincingly.

Her green eyes sparkled with mischief as looked straight at me, "Are you sure you don't want to see more of what you glimpsed earlier?"

Now I knew for certain she had been teasing me all along with flashes of her lacy knickers. I was torn between taking the opportunity, and worried that we might inadvertently get caught.

"You know I would love to, but I'm worried about the time," I said.

"Let me help you decide," she replied, and without taking her eyes off me slid her hand down and felt for my hard cock through my shorts.

"God, Sarah, you'll get us both into such trouble," I said, reciprocating by running one hand down between us, over her flat stomach and onto the semi-transparent lace of her knickers, to cup her mound through them.

She lifted her hips to give me access and my middle finger automatically found the indent of her camel-toe and I slid it up and down, aware of how damp the gusset of her underwear had become.

"Oh yes," she mumbled into my mouth, moving her tongue deeper and more vigorously as my finger stimulated her more.

I knew we were getting beyond the point of 'just kissing' and if we didn't stop now, we would go far further. I glanced quickly at the clock on Sarah's bedside table and estimated that Jayne had been gone about 35 minutes already. I was worried she could return very soon.

"I think time is against us," I said, removing my mouth from Sarah's.

"Do you remember when I first asked your advice about what you would do if a girl 'offered it to you on a plate'?"

"When my mate Dave turned you down you mean, yes, of course I remember."

"You said, 'I guess I could be tempted, if it was someone like you for instance', it's what started it all off, wasn't it?"

"Well, yes, I guess so," I answered, wondering what she was getting at.

"Are you turning me down now?" she asked, giving me an innocent look.

I grinned at her, seeing how she had cleverly used my words against me and then managed to make it my decision.

"We have too much of a bond and you are too sexy for me to ever turn you down, but you must see how risky it is, we don't want to be caught, do we?"

"No, of course not, but all you have to do is this," she whispered, sitting up on her knees and putting a hand down to pull the gusset of her lacy knickers to one side, allowing my finger to slid in-between her bare and very wet, pussy lips.

"You really just want..."

"Yes, if you want to? We've probably just got enough time," she said, grinning back at me, that look in her eyes, as she then used both hands, with her arms crossed, to grip the bottom of her tight top and remove it over her head.

Seeing her breasts and solidly erect nipples, which have always been larger than Jayne's, come into view, just confirmed that where Sarah is concerned, I am a weak-willed man. I knew I had been procrastinating and trying to half-heartedly extricate myself in a way that didn't upset her, and at the same time make sure that we weren't compromised by Jayne's return, but in reality, at this point, I wanted nothing more than to fuck Sarah again.

I reached up and held one firm globe in each hand, gently squeezing, weighing them, and playing with the rubbery nipples, much to Sarah's obvious pleasure.

I wondered if she and Rob had not been having much sex lately, as her wantonness since we had been alone, was not really like Sarah.

With my cock making up my mind for me, my heart began beating faster at the risk we were taking. I let go of her breasts and lifted up enough so that I could push my shorts and boxers partially down my thighs in one movement. My hard cock was then pointing upwards just in front of where Sarah had left her knickers pulled to one side.

"That looks promising," she said, staring down at my cock that was already oozing pre-cum over the head.

She then lifted her hips slightly, and gripping me with her hand, pulled my cock towards her. Looking down, I could see that she had lined up my engorged cock-head and it was just engaged with the entrance to her vagina, surrounded by her damp, light-red, and neatly trimmed, pubic hair.

I looked up into her eyes pushing upwards as she lowered herself down, and felt the head easily side past her pussy lips and enter her.

"Ohhh," she sighed.

She dropped lower and I felt my cock slide further inside her.

"Oh yes, all of it Pete," she said, her eyes moving around in concentration as she accommodated my girth once more.

A final move and our bodies met together; my cock now deeply embedded in Sarah's very wet tunnel.

"Oh God, that feels good, doesn't it? she whispered, throatily.

"You feel good; you're so tight, almost like that first time," I said, surprised at how the walls of her vagina felt so snug around my cock.

"That's Kegal exercises for you," she said, making her muscles squeeze me even more.

She squirmed around a little more until I felt he head of my cock bottom out deep inside her.

"Oooo, that's really deep, I don't usually get to feel that," she paused, "can I ask... I mean...do you...ummm...get that deep with Jayne?" she whispered, embarrassed, but excited to ask the question.

From the very beginning, Sarah had liked to hear what I did with Jayne. I remembered that she went as far as to creep downstairs one time to surreptitiously watch us having sex long ago before she had ever had sex. Then the last time, after the party, she shocked me by actually helping to put my cock into her sister, all without her knowledge. I knew that it turned her on, and although surprised, I just assumed it was a little fetish she had that Rob knew nothing about.

"Ummm, only occasionally," I answered feeling a bit self-conscious, "she doesn't like to feel it bump her deep in there like this."

"Ohhh, I do, like it is now, just touching my cervix I think," she said, shuffling around a little, "it sort of makes me feel that we are as close as we can get."

I moved my hands back onto her breasts as I felt her begin to rise up, my cock sliding slowly out of her until it was back to being only just lodged in her entrance, then sliding all the way back down until I felt it could go no further. That slow sensual movement was so erotic that I didn't think we would be able to do it for very long before one of us, probably me, was going to come.

"I should have taken my skirt off, I love to see your cock going into me as well as feel it," she confessed, lifting the hem of her short skirt up to her waist.

Now, by looking down, we could both see my cock sliding fully inside her to one side of her knickers, and then almost out as she alternately lowered and lifted her body.

I caressed her breasts and nipples, pinching the dark nubs between my thumb and finger in the way I knew she liked, just short of painful.

"I can't believe we're doing this here," I said, as I felt her speed up and I began to match her with upward thrusts of my own.

"Do you want to stop?" she asked, breathing harder, a knowing smile on her increasingly red face.

"You know the answer to that one."

"Oh yes, harder," she groaned, "I can feel you so deep inside me."

We were both breathing heavily with the exertion and getting hotter by the minute, the risk factor of discovery increasing along with it.

"I'm getting close," I said, through my laboured breathing, "are you?"

"Not far, not far," she managed, and then slid her finger down and began to rub her clit at the same time as moving even faster on top of me.

I felt it starting to happen for me, "I'm going to come, is it alright to..."

"Yes, yes, come inside me," she almost shouted, cutting me off.

Within moments I felt the first pulse begin at the base of my cock and travel up its length, and then the release as the first rope of cum splashed high into Sarah's vagina, followed rapidly by a second and third, that I imagined fully coated her cervix.

"Oh my God, Oh fuck," Sarah cried, as she felt it, "I'm coming now, I'm coming..."

I hoped the walls were thick.

She kept moving, encouraging the remaining amounts of cum to leave me. Her tight tunnel gripped me even more, despite the lubrication, while her body shook above me. Her legs, which were either side of mine, clamped harder together and her stomach rippled as her orgasm rolled through her for long minute.

"Oh, fuck, Pete," she gasped finally, lowering her body to lie on me with my cock still inside her.

Her naked breasts were pressed against the hairs on my chest. She twitched a couple of times then lay still as I gently stroked her bare back while her breathing slowly returned to something like normal.

"I feel like you have flooded me," she chuckled quietly, "you been saving all that up? It felt like there must be gallons."

I had an idea what she meant, because as my cock began to soften, I could feel the wetness starting to run out of her onto the base of my cock and balls. I glanced at the clock.

"We are going to have to move, I am sure they could be back any minute."

"It would be nice if they weren't, just yet," she replied, "but I know you are worried."

Slowly she sat up again, then lifted herself off me. My cock slipped out and we both looked at where it had been, to see a thick stream of our mixed juices and cum slowly coming out from between her now plump and reddened pussy lips; her knickers remained bunched to one side in a very damp mess. Her face was also red from the heat and exertion, I wondered if mine was the same.

"I think I need to change these, while you get dressed and take your toolbox downstairs," she said, giggling at the unintentional inuendo.

"What about this?" I indicated the wet stain on the bed cover.

"Don't worry, I am the only one that will be in here, I'll change it later."

I did as she said and walked down the stairs carrying my toolbox and headed for the front door.

Just as I opened the door Jayne's voice from behind me said, "You look hot."

I turned and saw that the back door was open, Jayne and the children seemed to have just arrived back and we hadn't heard them.

"Yes... it was...ummm...hard work in that confined space," I stuttered.

"I'm sure it was...is Sarah ok with what you've done?"

"I think so, she's just tidying up, she will be down in a minute," I said, loudly, hoping Sarah had heard.

"That's good, I bet you could do with a drink now?"

"Errr, yes. Thanks," I replied, moving towards the front door to put my toolbox into the car.

I wondered how long she had been standing there.......

When I got back from the car, Sarah was already in the kitchen with Jayne and from the noise outside I knew the children were in the garden playing.

I was pleased to see that Sarah was still wearing the same skirt and top, as it might have been a bit odd to Jayne if she had changed, although the skirt did look a bit creased now. There also didn't seem to be any sort of atmosphere. They both had a glass in their hands and a cold drink was waiting for me on the table.

"Everything is working okay Sarah tells me," Jayne said, looking at me over her glass.

"Yes, all good," I replied, trying not to look directly at Sarah.

"Sorry to have spoilt your morning," Sarah said, "do you want to stay for a bit of lunch, I'm sure I could rustle something up?"

"Thanks, but no, I think we should get back," Jayne replied for us, finishing her drink.

"My shirt should be dry by now, I'll go get it and call the children in," I said.

When I got back with the children, Jayne and Sarah were just finishing a conversation.

"Next Saturday, see you then," Jayne finished.

We said our goodbyes and piled into the car.

"What about next Saturday," I asked, as I drove away, the children waving from the back seats.

"Oh, I've invited Rob and Sarah for dinner next Saturday evening, Mom will babysit their children and ours, so they can stay as long as they like," she answered.

"Great, sounds like it might be a good evening."

"Yes, I thought it might be as we haven't been out together since the party a few weeks ago. And that was fun, wasn't it?" she said, looking sideways at me.

"Yes, yes, it was," I replied, wondering now how much she did actually remember.

"You've always got on well with my sister haven't you, even before we got married?"

"Well, yes, I guess so, I think you said I was one of the few boyfriends you had that she liked," I said, wondering what had prompted this.

She laughed, "Yes that's true, she is very picky, so you did well to get her approval."

"Has she said something then," I asked, feeling nervous about the answer.

"No, but you like her, don't you? And I see the way she looks at you sometimes and I wonder what she is thinking."

"We have spent a lot of time together over the years, holidays, outings, helping each other like today and all sorts of things, haven't we? It's bound to create some sort of fondness between us all. I'm sure Rob feels the same towards you. I can't say I've noticed anything different," I said, hoping to put this line of conversation to rest.

"Yes, you're probably right," she said, pensively.

No more was said on the subject, and we soon arrived home where I quickly went and had a shower for obvious reasons, claiming 'sweaty work'.

Later that evening, I got my second 'reward' and fortunately by then I was sufficiently revived for us both to enjoy it.

There was however a small nagging worry about out conversation in the car and why she had brought it up, but I put it to the back of my mind and hoped it was nothing sinister.

**************************************************************************************************

The following Saturday afternoon, we had taken the children to pick up Jayne and Sarah's mom and then taken them round to Rob and Sarah's house where she was to stay the night and look after the children, as she had before. She enjoyed having them to herself and generally they behaved well with her.

Rob and Sarah arrived about 7:30pm with the usual couple of bottles of wine. We had planned to have an outside BBQ, but during the afternoon, although still warm, a fine rain had begun to fall and everywhere was very damp. We decided to change the menu and use the chicken pieces we had ready to make a tasty curry instead and eat indoors.

We were all in casual attire; the two ladies in bright, short, summer dresses and heels, while us guys wore more conservative short-sleeved shirts and shorts. I noticed that when either of the two ladies passed in front of the floor-to-ceiling sliding windows to the garden, the light shone through their thin dresses, outlining the figure underneath. It also hadn't escaped my notice that Rob was craftily watching this unintentional show too.

We sat and had an aperitif that turned into two, or more, drinks for some. It was very relaxed, and the addition of a little alcohol made it more so. We chatted amiably about recent events, family matters and various news items we had heard for perhaps longer than we thought.

"I think we ought to serve some food before we are all too drunk to eat," Jayne said, smiling.

We all went into the dining room where the table was all laid out with more wine or beer for those that wanted it. It didn't take long before we heated up and served the curry we had made earlier.

"Wow this is a hot one," Rob said, having taken a mouthful of the curry, "a bit like these two beautiful women here," he added, taking a good drink of the beer, he had chosen.

"Goodness Rob, such compliments, but only Pete knows whether that's true about me," Jayne said, winking at me, her face slightly flushed.

I glanced at Sarah who quickly rolled her eyes, as usually Rob was the quiet one, but she knew that the pre-dinner drinks were obviously already taking effect.

"Well, being sisters, I'm sure you are both fantastic," he said, "here's a toast to you both," and downed another long drink, that we all had to follow.

I noticed that glasses were being emptied at quite a rate, and I had to open more bottles of wine, probably to quench the heat of the food, but everyone seemed to be enjoying it. As we ate, there was the usual quiet banter that gradually became livelier as the meal progressed.

The atmosphere was now very relaxed with a few 'adult' jokes -- yes, I was guilty of some of them- and various innuendos that had the ladies giggling, aided by the alcohol consumption.

Once again, I noticed that Jayne and Rob seemed to be more affected by the drink, and sometimes burst out laughing at things that were mildly amusing but that they seemed to find hilariously funny.

Eventually, everyone had eaten enough and although we had a dessert ready, we all decided to pause awhile as the curry and rice with the various side dishes had been very filling.

"Why don't we all go back into the sitting room with our drinks?" Jayne suggested, carefully pronouncing her words, "it's a bit more comfortable."

"Good idea," Rob agreed.

So, taking our glasses and the various wine bottles we had open, we adjourned back to the sitting room and made ourselves comfortable on the sofa and in the easy-chairs.

"That was a great meal," Rob said, filling his glass again.

"I second that," Sarah commented.

Jayne was smiling at the compliments, but I could see that she had rosy cheeks and had probably had more to drink than normal.

"I have an idea," Jayne said, suddenly, "lets play a game."

"You mean a board game?" I said.

"No, we would be bored with that," she laughed out loud at her own pun, and Rob joined her, "I mean something more interesting."

"Like what?"

"Well, last year I bought a game by mail order and haven't opened it yet. I was going to take it with us when we all went on holiday, but when I read the box, I thought it might not be appropriate as we had the children there."

"I didn't know you had bought any sort of game," I said, giving her a puzzled look, "but I am intrigued."

"I'll go and fetch it, and we can decide if we want to play."

Jayne disappeared from the room, using some of the furniture to maintain her balance.

"I wonder what it can be?" Sarah said.

"I hope it's not one of those trivia questions type things," Rob said.

"Afraid you'll lose?" Sara retorted, jokingly, as Rob pulled her a face.

"We'll soon find out; I can hear her coming back." I said.

A few moments later, Jayne reappeared with a white box in her hands.

Having sat down again, she showed us the box.

"I thought it was a simple 'Truth and Dare' game, but when I read the box, I realised it might be a bit....what's the word... raunchy," she giggled.

Everyone was also now intrigued as to what the game might be.

"Can I have a look at it?" I asked.

"Here you are," Jayne said, passing it over.

I read the printing on the box, "Hmm I see what you mean."

"What?" Rob and Sarah said, almost simultaneously.

"Well, it says... 'Adults Only. This game should only be played with consenting adults. Parts of the game may involve intimate revelations and interactions that some people may find intimidating or embarrassing. The basic rules are inside, and all players must agree to abide by them. You have been warned!' " I read out.

I was surprised that Jayne had bought it, but maybe she thought it was a harmless game like the one we used to play as children. I thought it might be fun but was not sure about the harmless part.

"Oh, that sounds fun, even a bit naughty," Rob piped up, also obviously having had a fair amount to drink. "I like the idea of 'intimate' and 'embarrassing', hands up who wants to play?"
"You don't mind what it might entail?" Sarah asked him.

He thought for a minute and had another drink from the wine he was now on. "We all know each other fairly well, it's not like we are strangers, but I'm sure there are lots of things we don't know that might be fun to find out," he said in reply.

"That's what I thought," Jayne joined in, "we have been on holiday lots of times together, got drunk, shared laughs and seen each almost naked on the beach and stuff, I doubt it's much more than that."

Rob and Jayne nodded their assent, so I looked at Sarah who seemed indecisive.

"Come on sis, what do you have to hide?" Jayne asked, "it'll be fun, I'm game, I didn't think you would be prudish," Jayne said to her sister, still grinning.

"Oh, ok then, but if it's going to be 'intimate' like it says, then I think I need another drink," she replied, pensively, and all eyes turned to me.

"I guess I'm outnumbered, so if you all want to give it a try, I guess we should open it and check out the rules," I said, and began to peel off the outer wrapping.

The box simply contained about a dozen different coloured sets of sealed 'flash cards' labelled 'Truth (male)', 'Truth (female)', 'Dare (male)', 'Dare (female)', a couple of dice, and a printed sheet with only a few rules.

"So, what do we have to do?" Jayne asked.

"It seems very simple," I said, looking at the rules, "basically, we throw the dice to start and whoever gets the highest score becomes 'The Asker' for this round and begins by asking the person with the lowest score 'The Responder' whether they want a Truth or a Dare."

"Ok, that seems simple enough," Rob said.

"Depending on the answer, 'The Asker' takes one of the cards from the appropriate pile (male/female/truth/dare) and reads it. If 'The Responder' asks for 'Truth' but refuses to answer the question, then they must take a 'Dare' from the appropriate 'Dare' pile. 'The Responder' automatically becomes the next 'Asker' and the remaining people throw the dice, the lowest score becoming the next 'Responder' " I read.

"I suppose that's so the same person doesn't do it twice in a row," Rob commented.

"What if they don't want to do the 'Dare'?" Sarah asked.

"Emm...let me see...ah, ok, it says, 'everyone has one 'Pass' card that they can only play once. If a player does not want to do the 'Dare', they can use this card to pass this one time only. However, this is an adult, fun, game and from the beginning relies on the consent of all players that they will answer the 'Truth' questions honestly and carry out the 'Dares' as described. Please make sure everyone agrees before you begin' and that's all it says."

I looked around at the other three.

"It sounds like it might be more interesting than I thought," Jayne said, a strange smile on her face.

"I wonder what the truths and dares might be," Rob said, some of his words not too clear now.

"Are you all sure about this?" I asked, "it does seem as though they are warning us to be prepared."

"We won't know, if we don't try it," Sarah said, her face a bit flushed too, "but as it stated, we all have to agree to go through with whatever it says or there is no point in playing it."

"Right," I said, "does anyone not want to play this now that you have some idea of what it involves?"

Everyone looked at each other, but no one wanted to be the one to dissent.

With that tacit agreement, I gave the two dice to Jayne to have the first throw, and the game began, no one knowing what would happen.

Rob got the highest score and Sarah the lowest.

"Ahhh, ok, so I have to ask Sarah," Rob said, "Sarah, Truth or Dare?"

"Truth."

Rob seemed to be enjoying the fact he was going to ask his wife a 'truth' question as he picked up the first card from the 'female' pile.

"Sarah, 'how many men have you slept with?' " he read.

"What?" Sarah asked, blushing, "you really want to know that?"

"Well, that's the question on the card."

"Yes...but...I didn't expect that sort of question."

"It's just a bit of fun," Jayne said, encouraging her, "we might all get asked the same sort of questions."

Sarah paused, "Ok, six then."

To give him his due, Rob never flinched, but just accepted the answer.

I got the lowest score next.

"Truth," I said.

"Where did you and your current partner first have sex?" Sarah read.

It was Jayne's turn to blush as I replied, "Ummm... on the sofa in your parents house."

"Was I in the house," Sarah asked, spontaneously.

"That's two questions, but yes you were."

I glanced at Sarah and could see a slight change in her eyes, a hint of remembrance, excitement, and mischief there now.

Rob was the next one to get the lowest score.

"Dare," Rob said quickly.

"Ahh, brave," I said, picking up a card, "Hmm, ok, I dare you to show us, for one minute, on your partner, one thing that she or he likes you to do with your hands in foreplay," I read out.

"You mean tell you or actually do it?"

Sarah looked a bit nervous at this turn of events.

"It says 'show', so you have to do it, it's a dare," Jayne emphasised, chuckling, "I'll get the kitchen timer, and we can use that to time it," she added, quickly fetching it from the kitchen.

Rob got up from his chair and went over to Sarah, who looked a bit worried about what he was going to do.

Jayne and I watched as he went behind Sarah and putting his hands round her, began to cup, and massage her breasts through her clothes. I could see he was also trying to pinch her nipples through the material.

Rob's intake of alcohol had obviously erased his inhibitions, as he seemed to be enjoying feeling his wife up in front of us. Sarah sat there, her face red as a beetroot, but as the minute slowly ticked away, I could see that her nipples had become obviously erect and tenting her thin dress, even through her bra.

The timer went off.

"Well done, Rob. I can see you liked that Sis," Jayne said, giggling again.

"Wait 'til it's your turn for something," Sarah replied, taking it in good humour.

On the next round, I was the lowest, but was undecided what to choose, as telling the truth about some things might not be a clever idea and it seemed pointless to play the game and lie.

"Dare." I decided.

Rob picked up the next male card.

"It says, 'I dare you to passionately kiss the first woman on your left for one minute'."

"Oh, really," I said, "not my partner then?"

"No, it just says 'first woman'."

Realising that the first woman on my left was Sarah and not Jayne, I looked at their expressions. Jayne seemed not to be phased and was smiling, but Rob had a slight frown.

"Rob?" I said, questioningly.

"We agreed to play," he said, unconvincingly, "so let's see you do it."

Wondering if playing this was a good idea now, I moved over to Sarah and began kissing her. Mischievously, I felt her tongue probing my lips and with the back of my head obscuring the view from Jayne and Rob, reciprocated, but not too vigorously that they would notice. If either of them did notice, they didn't say anything. Sarah made sure to use her tongue covertly, but effectively, until he timer went off, giving me an erection in the process.

We played quite a few more rounds, and all the truths and dares were of a similar fashion.

For example, Rob had to give Jayne a 'sexy' backrub through her clothes, Sarah answered '18' to a truth about when she lost her virginity and nearly gave away our secret by blushing and looking at me, Jayne answered 'yes' to whether she had ever sucked off her partner, Sarah had to stroke her partner over his clothes and show by his bulge that she had made him erect, there was licking of belly-buttons, and so on...

All these had a mild sexual element, but nothing too outrageous, so I didn't see what the warning was about on the box and in the instructions.

Until...

We had used up all of one set of cards, so Jayne opened another set whose backs were coloured blue, different to the white ones before them. No one attached any relevance to it as they were placed face down in the lid of the box.

We were all warm and relaxed by now with the drink as well as having had some fun touching, kissing, and hearing truths from each other, as the game demanded.

Jayne was next with Rob as the 'Asker'.

"Ummm, I'll go...'Dare'," she said.

Rob looked at the card, then re-read it again.

"I think the game has moved up a step," he said.

"What's the dare?" Jayne asked.

"Well," he cleared his throat, "it says, 'I dare you to sit for the next round in just your underwear'."

There was a silence in the room, everyone glancing at each other.

"You don't have to do it," I said, "you have a 'pass card'."

Jayne had been drinking steadily, as had we all, and just like Rob after the party last time, seemed to have also lost her inhibitions, and had a lusty gleam in her eye.

"No, I'll do it," she said, getting to her feet a little unsteadily.

Her sundress was very simple, and she easily dropped both thin shoulder straps and let the dress fall around her feet. It revealed that underneath she only wore a fairly see-through, set of white bra and knickers, her dark nipples and triangle of dark hair clearly visible through the semi-transparent material. She even did a couple of twirls before sitting down again.

Rob was staring at her; raking her with his eyes, while Sarah looked on, and like me, was surprised at her nerve to do it.

"Rob, your tongue seems to be hanging out," Sarah commented, with a nervous laugh.

"Sorry Jayne, I mean, I've seen you in a bikini before but umm... not quite like that," he mumbled, shifting uneasily in his chair.

Jayne just smiled at the compliment.

"Lets move on," I said, wanting to take some of the focus from Jayne.

Coincidentally, I got the lowest score next.

"Dare."

Jayne selected the next card.

"Mmmm," she said, reading it, "we do seem to have moved up a gear."

"What do I have to do?"

She read, slowly, "I dare you to put your hand into the underwear of the first lady on your right and finger her for one minute'. Ohhh, and that's me," she added, looking at me and grinning.

"Is that what it really says?" I asked, not sure if she might have made it up out of devilment.

"Look," she passed the card to me.

She hadn't made it up.

I went over and sat on the arm of the chair she was occupying and with the other two watching avidly, put my hand on her bare stomach.

"You're sure?"

She nodded and opened her legs.

I slipped my hand down under the elastic of her sexy knickers and palmed her mound, then slid my middle finger between her pussy lips into a surprising amount of wetness. For the required one minute, I then alternated between slipping my finger inside her and then rubbing her clit with her own lubrication. Jayne shut her eyes and from the small sighs, seemed to be enjoying the sensation and exhibition she was giving, while the other two sat in silence watching the movements of my hand in her knickers.

When the minute was up, I stopped, and withdrew my hand, Jayne opened her eyes and looked disappointed for a moment.

"Pity it wasn't two minutes," she giggled, and stood up to put her dress back on having fulfilled that dare.

I could see Rob had a bulge in his shorts and Sarah's face looked flushed, but not from the drink.

"I wonder what's next, I'm a bit nervous now," Sarah mused, as I went back to my own chair.

She was soon to find out.

Being the one who was exempt, I watched as the others threw the dice.

Sarah's face showed her trepidation when she scored lowest and realised it was her turn.

"Errrr, I'm not sure what to choose, but as the rest of you seem to prefer a dare, I'll go for that too, so 'Dare'," she said, looking worried.

I picked up the next female 'Dare' card.

"It says, 'remove your lower outer clothes and give a lap dance, for two minutes, to the man on your right',"

"Oh, that's me," I said, glancing over at Jayne.

Sarah hesitated.

"Go on sis," Jayne slurred a little, "give my hubby something to remember," she grinned.

I looked at Sarah and shrugged.

She in turn slowly stood up, "I think just lifting my dress up should be enough," she said, moving over towards me.

She lifted the bottom of her dress up to her waist, exposing similar sheer knickers to Jayne's underneath. Her bush of dark red hair was clearly showing through as she sat on my lap, her back facing me. She shuffled around until I knew she could feel my now hard cock in-between her bum cheeks and did her version of a lap dance that was more akin to a dry hump, but I didn't mind. It was erotic feeling what she was doing to me in front of Jayne and Rob, who just sat and watched for the full two minutes.

We continued with the blue coloured 'Dare' cards and hardly anyone took a 'Truth'. Although the game had stepped up a level, there was the same sort of dares for everyone; touching or sucking bare nipples, fingering under clothes by both sexes, removing underwear with teeth only, dry humping in various positions, etc, and so it went on, until we had used all those cards.

We moved onto the red cards.

It had come back to Sarah to be asked and again she chose 'Dare'.

Her husband took a card and read..."It says, 'suck the cock of the first man on your left for two minutes'."

"Wow," Jayne gasped, looking over at her sister, "these red cards are a bit wild, are you going to do it?"

"You mean I have to do it to Rob in front of you?" Sarah said, nervously.

"Of course."

"Rob, shall I pass?"

"I don't mind either way," Rob said, with his alcoholically induced bravado.

"Really?"

Rob looked at her and nodded.

Sarah bit her bottom lip, trying to decide, "Ok then I'll do it," she said, firmly.

Jayne and I looked on in surprise and amazement as she went over to Rob and knelt in front of him.

I don't think we believed she would do it, but instead would back out at the last moment.

However, she unzipped his shorts and then paused.

Then, almost as if a switch had been thrown, and without any more hesitation, she put her hand inside and fished out his now erect cock. It was uncircumcised and looked an average sort of length, but not as thick as mine. I remembered Sarah doing this to me, and my own cock became erect again thinking about it.

Sarah then slid his foreskin back and took the whole head in her mouth.

Jayne's eyes opened wide as her sister began to move her head up and down on Rob's cock, taking more each time.

"Goodness, I've never seen a couple do that and didn't think you would actually do it," she said, staring, and totally mesmerised by seeing Rob's cock going in and out of her sister's mouth.

Rob's eyes took on a slightly glazed appearance, while I just looked and wished it were me.

She bobbed her head up and down taking about half of his cock into her mouth before pulling off and then going back down again. I knew how that felt when Sarah had done it to me, and my cock became even harder in my shorts.

Once the two minutes were up, Sarah wiped her mouth and went back to her seat leaving Rob to put his cock back into his shorts and zip-up.

"Maybe we should stop there," I said, "I think the warning on the box was right."

"What?" Sarah said, "no, I think it's only fair we continue now that at least one of us has gone that far."

"Well, what is the consensus?" I asked.

"I thought that was, very...arousing, so I vote for carrying on," from Jayne.

"Yes, very," from Rob, glancing at Jayne with a lascivious grin on his face.

"As Sarah has already more or less agreed, that sways the vote, so remember you all agreed and let's see what's next," I said, picking up the dice.

Rob got the lowest this time, and Sarah picked up his 'Dare' card, "Ohh, are you ready for this," she said, looking over at her husband.

"What?" he said, sitting up and paying more attention.

"It says...' lick the pussy of the first female on your left for two minutes'."

We all realised at about the same time that this meant Jayne.

"Oh wait, this is a bit different to doing something to your own partner," Jayne said.

"Yes, I'm not sure about this," I added.

"Just because it's Jayne you mean?" Sarah said, raising one eyebrow.

"It's ok, I'll play my 'pass' card," Jayne said.

"No, you can't," Sarah again, "only the one who is about to do the dare, which means Rob, can do that."

"So, you don't mind if Rob does it?" I asked.

"Well, you kissed me as a dare, and we've done other things in the game, anyway we all agreed to play the game, no exceptions," she said.

"Kissing someone is a bit different to this dare though, isn't it?" I said.

We all looked round at each other, uncertain about crossing this line.

Rob got up from his chair, his obvious erection tenting his shorts, "Jayne, is it ok to...?"

Jayne looked at me for some sort of negative sign, but I didn't want to be the killjoy, and have it remembered in the future, so I quietly nodded.

Jayne repeated the nod to Rob.

Rob knelt in front of my wife, and while watching her face for any sign of refusal, slowly put his hands up under her dress and then bringing them out again, her pair of fine, white, knickers in his hand. While Jayne sat there passively, he then took hold of the bottom of her dress and slid it up her long thighs and over her hips, revealing her dark triangle to us all.

I wasn't sure what to think.

It was sexy seeing her naked pussy in front of us, and I remembered how Sarah and I had watched Rob finger-fuck her that night without them knowing we had seen them. I rationalised that this wasn't much different except it was being done openly.

Sarah had moved to the edge of her seat to see better.

Slowly Rob pulled her bottom to the edge of the seat cushion and placed first one leg, and then the other, one on to the cushion opening her legs wide. He didn't look for any other sign of agreement but moved his head into the 'V' of her legs and buried his face in her dark pubic hair. The music had just finished, and it was so quiet that we could hear his tongue begin to lap at her folds and the sighs that Jayne began to make.

Rob seemed to be making the most of it, running his tongue up and down, using his fingers to open her up to push his tongue in further. Jayne seemed to be loving it and showing no reluctance to this public display which I thought was totally out of character.

Sarah was watching intently, her tongue occasionally running over her lips.

Rob seemed to have switched his attention to her clit as far as I could see and had Jayne breathing faster and writhing on the chair.

The two minutes passed quickly, probably too quickly for Jayne, and Rob had to return to his seat, passing Jayne's underwear back to her so she could slip them back on.

"Wow Rob, I didn't know you had it in you," Jayne said, grinning.

"Nor me," Sarah said, quietly.

Rob said nothing but sat there with a cheshire cat's grin on his face.

"Do you think we should continue?" I asked again, "it seems to be getting very...emmm..."

"Fun?" Jayne butted in.

"Not quite the word I was looking for, but how about you two?" I said, looking between Sarah and Rob.

"I think it's fun too," Rob said, and I wasn't surprised as he seemed to have been having the most fun so far.

Sarah looked pensive again for a moment, "It's ok, it is getting to be very sexy and intimate... but it's not like we are strangers, so I will carry on if you all will," she said, making up her mind.

"I don't mind," Jayne said, huskily.

I wondered how we might all feel tomorrow when we had sobered up, but for now, we had all lost most of our inhibitions about touching one another, partner or not and no one made any complaints, and all seemed to be enjoying the new-found fun.
I got the lowest score in the next round and with some trepidation continued the theme and said 'Dare'.

Rob picked out a card and read it to himself. The expression on his face changed to one of disbelief.

We all waited anxiously to see what the dare would be.

"Come on Rob don't keep us in suspense," Jayne said.

"Err...Umm... well," Rob faltered, looking over at Sarah, "it says," he paused again, " 'put just the head of your cock into the first female vagina on your left'."

I realised that would be Sarah and wasn't sure what to do, the meaning of the warning was becoming clear, and the game seemed to be rapidly spinning out of control.

"Ohhh, wow," I gasped.

Jayne laughed out loud, "Well sis, it seems you're the lucky girl."

I looked over at Jayne and she seemed to be genuinely enjoying the awkwardness of the situation and not at all bothered by the dare I was to undertake with her sister.

Rob and Sarah kept looking at one another, exchanging some unspoken thought it seemed.

"Would you...umm... like to play your pass card?" Rob asked.

I looked quickly at Jayne again and she shook her head 'no' to Rob's question, surprisingly giving me the go ahead.

My cock had already grown hard at the thought of what I was about to do, although being an exhibitionist wasn't really my thing.

Rob looked tense as I got up and moved over to kneel in front of Sarah, just as Rob had done to my wife earlier.

Sarah's face was very red, but she made no effort to stop me as, like Rob, I slid my hands up under her skirt and brought them back out clutching her warm, purple, lacy, knickers.

Rob cleared his throat, I knew he wasn't happy, but I didn't feel guilty after what he had enjoyed doing to Jayne.

Just as Rob had done, I gently slid Sarah to the edge of the armchair by pulling on her legs then lifted each leg onto the arm.

I already knew what she would look like, but as her trimmed dark red bush of pubic hair came into view, it excited me afresh.

To an utter silence in the room, I slipped my zip down quickly and extracted my now rock-hard cock. Looking up at Sarah, I could see she was biting her lower lip whether in panic, anticipation, or trepidation, I didn't know.

Moving closer, I saw that there was what looked like a slight sheen of moisture on her swollen pussy lips, so maybe it was excitement after all?

Jayne was now leaning forwards to see better, with Rob looking on warily from the other side of Sarah.

"Are we really going to do this?" Rob asked, anxiously.

"It seems only fair," Jayne replied for us all.

I could see Rob's brow was furrowed in a frown.

My cock contacted Sarah's pubic hair, and I felt her jump. Taking it in my hand, I rubbed the exposed head up and down between her labia, surprised at how much moisture there actually was. After a few swipes up and down I positioned it at her entrance and gently pushed.

The engorged head of my cock slipped easily inside her.

"Ohhhhhh," she said, quietly.

Rob let out a gasp of breath he had been holding.

"That's far enough in, it said 'just the head'," Rob said, tersely and obviously unhappy.

I didn't push in any further, but my cock was twitching of its own accord, and I began to wonder if the sight and feelings might make me come, which might not be a great idea.

"Do I just sort of stay like this," I asked, wondering if I was supposed move or do anything else.

"How about taking it out and putting it back in," Jayne said lustily, apparently quite turned on by seeing her husband's cock-head inside her sister.

"That might be... nice," Sarah agreed, very quietly, but her eyes giving away her excitement.

Rob seemed transfixed, almost in shock at seeing my cock partially in his wife.

Not waiting for a consensus, I pulled out and pushed back in but slid a bit further into her than I intended.

Sarah let out another gasp.

"That's....too far," Rob complained on seeing half my cock now in his wife.

"If Sarah and I are ok with it, you should be," Jayne goaded him, having moved even closer to stare at my cock splitting her sister's labia apart.

I moved my hips back and forwards just a little, having the effect of moving my cock out and in, just short of really fucking Sarah in front of Rob and my wife, which I now longed to do.

"Sarah and Pete might feel differently if it was me doing this to you Jayne," Rob continued, loudly, still staring at where Sarah and I were joined.

I knew we had all had quite a few drinks by now, but I wasn't prepared for Jayne's next words.

"Why don't you come over here and try?" Jayne said, moving to sit at one end of the sofa, her legs outstretched, her skirt halfway up her long thighs.

"Wh...what? Really?" Rob said.

"You heard me," Jayne said, "it might balance things?"

Sarah raised her eyebrows, looking a bit shocked at her sister.

I too couldn't believe what I had heard, she was openly asking Rob to put his cock in her.

"That's not part of the game though," I said, disbelievingly.

"I think we have gone way past any game. What do you think Rob?"

I was a bit dumbstruck for a moment. I never thought when we began the evening that I would be in the weird situation of having my cock partly in Sarah, with Jayne's approval, and then with Jayne virtually agreeing to swap partners. It all seemed a bit like an hallucination or dream, and I wondered if someone has spiked my drink and that's what was happening.

Then my mind went back to the strange conversation Jayne had had with me in the car last week. Did she know something had gone on with me and her sister?...Hmmm...

However, there was no denying that I could see and feel my cock twitching in Sarah's snug vagina, so I was fairly sure that part was real and erotic.

"I dunno, it's not what I envisaged for tonight," I butted in, wondering about how far across the lines we were going to go.

"Maybe it would even things up," Rob said, now wanting his 'share' of Jayne.

Sarah was not saying anything but seemed to be deep in thought.

"I think... Umm...I think as we have gone this far, as Rob said, it would make us all even if we were all just doing the same thing, but for this one time only," she finally said.

Knowing that some element of taboo turned Sarah on, I began to suspect that she wasn't as reluctant as she was making out and a sudden tightness and then a release around my cock, made me think I might be right.

It seemed a lot longer, but suddenly the two-minute timer went off, startling us and making it decision time.

"Well, do you want to do what they are doing?" Jayne asked.

Rob's face changed to more of a grin, giving me a look before he moved the few steps towards Jayne.

My mind was in a bit of a turmoil as I didn't really want Rob to do what I was doing to Sarah, but I could hardly object from the position I was in. I realised I would have to accept whatever was going to happen.

With another short glance at us, Rob began to kneel down in front of Jayne.

"How about taking those off first," Jayne said, pointing to his shorts.

He hesitated for a moment, as if he suspected that Jayne was playing some huge joke on him, then his desire took over and he pulled both his shorts and underwear down and stepped out of them, before taking his place in front of Jayne, his erection poking out in front of him.

I slid out of Sarah so I could turn round and see what they were doing.

Jayne looked across at me and patted the seat of the sofa next to her, "I think you two should come over here, so we are all together," she said, obviously enjoying herself.

This was getting weirder by the minute.

Sarah gave a small shrug, got up, and moved to sit on the sofa near Jayne. I meekly followed her.

"Come on Pete, do what Rob has done," Jayne said.

I had no choice but to copy Rob by dropping my shorts and underwear and then Rob and I knelt down simultaneously in front of each other's wives. This was crunch time.

"Look, we are all fairly inebriated, don't you think we should just stop now?" I tried.

"I want to feel what my sister normal does now that she has felt you," Jayne said.

"But only just this one time," Sarah said, resolutely.

"Of course," Jayne replied, lifting her bottom up and sliding her knickers down once again.

Jayne slid forwards, opening her legs to either side of Rob kneeling in front of her, her dark triangle and swollen pussy lips lewdly exposed.

Sarah and I watched, still not sure it was going to happen. Rob moved closer until the head of his uncircumcised cock was touching Jayne's dark hair.

He was ignoring us and looking straight into Jayne's eyes as he rubbed the head of his cock up and down, lubricating it in what we could see were her copious secretions. Then, slowly, we saw the head of his cock open her up and the head side into her.

I didn't know what I was feeling. Unlike Sarah, apart from porn, I had never seen anyone have real sex in front of me. The 'game' had gradually progressed from innocent 'dares' to this point. We hadn't given any thought to condoms, so now I was seeing Rob with his cock bareback inside my wife.

Sarah shook me out of my thoughts.

"Your turn Pete," she said, widening her legs as Jayne had done to allow me access.

Rob turned to watch as I pushed forwards and easily entered her a short way as before.

Not a word was spoken as Jayne slid a bit further on the sofa towards Rob and his hips moved forwards to meet her; his cock penetrated to halfway.

Sarah and I did the same thing.

It became obvious that neither of us were just going to stop there, and with a sigh from Jayne, I saw Rob's cock disappear up to the hilt into her waiting vagina.

I wasted no time in pushing the rest of my cock into Sarah and was met with a similar gasp as our pubic hair crushed together.

Despite what Sarah and I had done in the past, I had never thought of having any sort of 'wife swapping' with Rob but seeing him fully embedded in Jayne and looking down to where I was the same in Sarah, was very arousing and exciting in a way I had not contemplated before.

Gradually Rob withdrew his cock and then plunged fully back inside my wife, much to her obvious pleasure.

I looked at Sarah and did the same, and then both of us couples began to seriously fuck each other.

We all began to make sighs and moans, glancing sideways from time to time to see what was happening with our partners. Seeing and hearing what Rob and my wife were doing was much more erotic than I would have ever thought.

I think I was the first to run my hands over Sarah's dress-covered breasts and search for her nipples, but out of the corner of my eye I saw Rob follow suit with Jayne. However, it was Jayne who was the first to pull her dress up over her head, and then release the clasp on her bra, leaving her naked, with Rob fondling her now bare breasts as he slowly fucked her.

I looked Sarah in the eye and indicated with my head Jayne's nakedness. She quickly decided not to be left out and copied Jayne's example, becoming as naked as her sister. Rob and I were then able to stimulate their bare breasts and nipples without the encumbrance of any material.

I tugged off my T shirt with only a brief pause and saw Rob do the same leaving us all now nude.

The noises of our heavier breathing and moans got louder as our excitement grew and our speed increased, with both wives having red faces and sweat dotting their brows.

"Oh, Yesssss," I heard Jayne say loudly, "harder Rob, harder." Which I knew from experience meant she was getting close to coming.

Hearing her sister urging Rob on must have had an effect on Sarah as she began to move her hips even more rapidly and strongly towards me, trying to get as much of me inside her as she could.

I didn't know what Rob was feeling, but I knew that the sensations I was getting low in my groin was a prelude to me coming and it wasn't far off. As we hadn't thought of condoms, I didn't know what Jayne intended when the moment arrived.

I didn't get time to question it, as with a very loud grunt, Rob slammed his hips forwards burying himself in Jayne.

"Oh yes, God, Ohhh," she cried out several times, as they clearly came together, Rob pumping his seed bareback into my wife.

"Fuck me, fuck me Pete," Sarah cried, on realising her husband had just filled her sister with his cum.

I wasn't far behind and with only a few more thrusts, felt my own cum forcing its way along my cock, erupting into Sarah. She took about another thirty seconds once she felt me come to reach her own peak, then began lifting her hips in several mighty thrusts, bottoming me out inside her.

The pulses kept coming, draining every drop of cum I had into her.

I could feel Sarah trembling from the effect as her orgasm crashed through her body, her vagina involuntarily squeezing me. I was sure that it was Sarah's most powerful climax that I had witnessed in our various times together.

I looked over to see that Rob had collapsed forwards onto Jayne, breathing heavily, his head resting on her bare breasts.

I pulled Sarah towards me while squatting down on my heels, gradually sliding her off the sofa onto my lap, my cock still deep inside her and her legs either side of me. Putting my arms round her back I pulled her tight against me and we rested there.

It was several minutes before anyone stirred, and now that the rush of sexual arousal, euphoria, and excitement had slowly diminished, there was an embarrassed silence as each of us processed in our own thoughts what had happened.

"Well, that was a bit...emmm...different," Jayne said, quietly, the first to speak.

"You can say that again," Sarah agreed.

"Did you enjoy that with Pete?" Jayne asked, a quizzical expression on her face.

"Umm...yes... it was as you said, 'different'," Sarah replied, her face neutral, "how about you with Rob?"

"About the same," she said, enigmatically, looking her sister directly in the eye.

My cock was gradually softening now and the joint secretions from me and Sarah were beginning to make themselves felt as they ran into my pubic hair and around my balls.

"I think we might need to go and clean up." I suggested, as a way of breaking this up.

I saw Rob move away from Jayne, his cock now hanging limp just as Sarah lifted herself up from my lap, and my cock slid out.

"It was fairly amazing though," Rob said, looking a bit dazed, as he glanced back at Jayne's still open legs and dark triangle, and then at the white liquid running down his wife's inner thigh.

"Just one thing though," Sarah said, slipping her dress back over her head, "this was a once only...wasn't it?"

We never did get to eat the dessert.
