Stimulation Club

Zack's news of a unique club makes his twin sister curious.

Author Notes

First things first, I want to say a massive thank you to everyone for the truly incredible support my first story received. Back when I posted it, I figured it would maybe get a couple hundred views and that would be awesome. So, when I checked in roughly a week later and saw just how much people seemed to like it, saying that I was shocked would be a gigantic understatement. So again, thank you so, so much for reading!

Now, onto this story. It took a bit longer than I expected, but hopefully, the wait is worth it. Like with Remote, this is another longer chaptered one, although there's a little bit more of a build-up this time before things start to heat up. I hope you'll enjoy it just as much!

Session 1



"Anything interesting happen at school today?" my father asked as we settled down for dinner. It was his usual, regular as clockwork question that both my twin sister and I were always tired of hearing. We'd both learned to stop complaining about it long ago, given that doing so never accomplished anything, instead usually opting to reply with a shake of our heads or a wordless grunt--the latter being my personal favorite. Occasionally, something noteworthy did come up, and today was one of those rare days.

"As a matter of fact, I joined a pretty interesting club today," I announced after I finished chewing a bite of steak. It wasn't entirely the truth since I'd been a member of the club for just over a week by now, but I'd finally decided to bring it up with my family. "It came up at the end of my painting class and sounded too interesting to pass up so I decided to check it out."

Dad's eyes lit up in excitement at the news, nearly causing me to roll my own in response. While I very much understood that our parents loved us and wanted to know everything Zoey and I were up to, we were in our first year of college at this point. Worst case scenario, I supposed that meant we only had three more years of putting up with it.

"Oh? Did you finally decide to join a sports club?" he asked before eating a forkful of mashed potatoes.

This time I did roll my eyes, shoving down my annoyance at the question. I knew it was only because back when he'd been in college he'd been a member of the football team and, as a result, he'd always wanted me to follow in his footsteps, but sports had never interested me much at all. I'd always been far more interested in art--painting and sculpting in particular--and it felt like he still hadn't accepted that. Out of the corner of my eye, I caught Zoey giving me a worried look, but I wasn't about to start that fight at the dinner table. Besides, this was all going to be worth it when he heard the name of the club.

Slightly smirking, I shook my head. "Nope, doesn't have anything to do with sports. It's called the Stimulation Club."

My dad's reaction exceeded all of my expectations as mashed potato sprayed everywhere, his eyes bulging comically wide.

"Mark!" my mom shrieked at him, giving me a quick worried look before turning to my dad. "Look at the mess you've made!"

Turning faintly red, my father finished swallowing the little remaining bit of potatoes still in his mouth before using his napkin to clean up the rest as best he could. "Sorry. I just--" His eyes fixed on me, brow furrowed. "Stimulation Club? What the hell were you thinking?"

Taking another bite of my steak, I chewed slowly instead of immediately responding. For her part, other than her clear frustration with the potato mess, Mom looked equally concerned, although slightly less so. Zoey, on the other hand, was clearly trying her hardest not to burst into laughter--her hand firmly pressed over her mouth while her green eyes twinkled merrily.

Swallowing, I looked back over at him. "Don't you think you should hear what the club is about before you jump to conclusions and start judging it?"

"The dinner table is hardly the place to discuss whatever sex club you've decided to join! I can't believe you'd--"

He cut off as Mom placed a hand on his arm, visibly squeezing as she frowned. "Don't be ridiculous. You know as well as I do that Zack would never do something like that, much less tell us about it if he did." Turning to face me, she gave me one of her serious looks. "You've had your fun, young man, now explain yourself."

"It's not a sex club," I said with a small smile, "despite what the name sounds like. They said that was the original name just to try and get people to join, but then it ended up sticking since it's funny and is an accurate description."

"So what is it then?" Zoey asked from where she was seated next to me, looking curious.

It was far easier to understand the club by personally experiencing it, but since I'd planned on bringing it up, I'd already come up with a reasonable explanation. "The more accurate name for it is probably the 'Imagination Club.' It's all about working on expanding your creativity and learning to use all of your senses when making something. Like, for instance, it's easy to paint a woman in a dress, but then it can become so much more by showing it blowing in the wind around her, and how that causes it to move."

Dad still looked a bit dubious, but both my mom and Zoey were slowly nodding along.

"That makes sense, but what does the club do to help with that?" Mom asked.

This was the tricky part because while it definitely wasn't a sex club, it was undeniably extremely sensual. "Well... we start by putting on blindfolds--"

"I knew it. It's a sex club," my dad said, his hand coming down on the table.

"Dad! Knock it off!" Zoey snapped before turning back to me. "Keep going, Zack."

"The blindfolds are, well, obviously to make it so you can't see anything. That's the sense we're already so used to when making art, so it doesn't need as much help as the others. Then, everyone pairs up and we just... talk. It's kinda hard to explain it, honestly, but one person describes something in as much detail as they possibly can and you try to picture it in your mind's eye."

"And that's it?" From my mom's tone, I could tell she was a bit skeptical. "There's no touching other anything else?"

Doing my best to keep a perfectly straight face, I nodded. "Yup, that's it. No touching." It was a lie, although not a very large one. There was technically touching sometimes involved, but only ever with consent from both members and only on the back. It was far easier to leave that part out, though, since it would only further make my parents think I'd joined an actual sex club. The other part I was making sure to leave out was that the club was almost entirely women, with only a handful of dudes.

Seemingly satisfied with my explanations, we all settled back into dinner, the conversation being replaced with the sounds of everyone eating a good meal. Once we finished, I was just about to take my leave when my dad spoke up again.

"And what about you, Zoey? Anything big happen?"

She shook her head. "Nope, nothing worth mentioning. Certainly didn't join an almost sex club like Zack did," she said with a wink in my direction.

"It's not a damn sex club!" I snapped, jumping to my feet and nearly sending my chair toppling over backward. Before anyone else could say anything I stormed off, stomping up the stairs to my bedroom. Earlier I'd worried it might be a mistake to bring the club up at all, but I hadn't expected Zoey to take my dad's side, even if she had almost certainly been teasing me.

The only reason I'd even decided to mention it was because the experience at the club had been truly amazing, opening my eyes to a new way of thinking about and creating art. It had been particularly well-timed since I felt like I'd fallen into a bit of a slump recently, especially after seeing how talented so many of my upperclassmen were. Back in high school, I'd felt like I'd been something special, only to realize in college that there were many people as good if not better than I was.

Closing the door of my room behind me--and not slamming it like I almost wanted to--I flipped the lights on and walked over to the easel in the far corner of my room at the foot of my bed. Stopping in front of it, I took a long look at the progress I'd made. Or rather, more accurately, the complete lack of progress. It was the true source of my irritation, and what had my temper on edge these days.

All I had so far was the vaguest shape of a human body imaginable, not even enough to say that it was a man or a woman, although I knew I was aiming for the latter of the two. It was especially frustrating because I'd started this piece well over a month ago, and this was as far as I'd gotten in all that time. Picking up my brush, I swore that today my lack of progress would finally change.

I'd just begun to feel like I was making some decent headway when a soft knock on my door broke me from my intense concentration. Glancing over at the digital clock on my bedside table, I was surprised to find the glowing numbers were showing that two whole hours had already passed. Before answering the door, I took a closer look at what I'd painted, noting that while the form was now at least far more feminine, I'd still made a disappointingly small amount of progress for the length of time I'd been working.

The interruption, then, was probably for the best. It was getting late, and continuing to try and force through my block any longer was unlikely to result in some kind of miraculous breakthrough--a lesson I'd learned long ago. Setting down my brush, I walked over to the door and pulled it open, having a pretty good idea of who it was on the other side. Unsurprisingly, I found that it was indeed Zoey, wringing her hands together. "What's up, sis?"

"Hey, can I come in? Wanna chat."

She was already leaning forward as she finished speaking, and I had no issue with her being in my room, so with a soft snort of amusement, I stepped back to hold the door open for her. "By all means. I'm surprised you'd want to be in the same room as a pervert who'd join a sex club, though."

Her face fell, and I immediately regretted the low blow. "That's what I wanted to talk to you about. I shouldn't have teased you about the club at dinner. I'm sorry. I feel like we usually get along really well and I don't want this hanging over us." She stopped talking, even though it seemed like she had more to say--looking at me with such a sad expression I felt my stomach clench.

Sighing heavily, I ran a hand through my hair in frustration not at her, but rather at myself. "Look, Z, I'm the one who's sorry, okay? I seriously overreacted downstairs and I shouldn't have blown up at you like that. I was pretty sure you were teasing me, but I'd just gotten so worked up from Dad's response."

She raised an eyebrow. "Even though you were specifically fishing for it?"

I couldn't help but laugh, despite the fact she was pointing out my own hypocrisy. "That's part of what I love about having you as my twin," I said. "You won't hesitate to call me out on my shit."

Zoey beamed up at me, and the sinking feeling in my stomach was immediately replaced by one of butterflies. I had to gently remind my body that no matter how beautiful my sister might look when she was smiling like that, she was my twin, and brothers don't get excited when their sister smiles at them--regardless of the situation.

"Nice to hear I'm not just a massive pain in your side. I've got several friends who say they can't stand being around their brothers, although I suppose none of them are twins." She looked thoughtful, her index finger resting on her lower lip in a pose that I captured in my mind for possible future inspiration.

"Maybe that's some of it, but a part of me doubts they're as incredible of a sister as you are."

"Now you're just buttering me up," she said, her cheeks taking on a very faint rosy hue.

"No, me? Never," I said, fighting not to smile. "Anyway, it is getting late and I've got an early morning sculpture class tomorrow."

Zoey wrinkled her nose. "Ew, gross, waking up early. You know my earliest comp-sci class starts at ten? We may be twins, but I don't understand how you can function so early in the morning. Before you go to bed early like an old man, can we just chat for a bit longer? There's something else I want to talk about."

"Old man?!" I exclaimed in mock outrage, taking a step backward. "We're literally the same age, that's kinda how the whole twin thing works. So if I'm an old man, then that would make you an old lady."

Placing her hands on her hips, she gave me what could only be described as a flirty look. "Do I look like an old lady to you?"

My eyes flicked up and down the length of her body, seemingly of their own volition at her words. Her long brown hair, up in its usual ponytail. Her green eyes, that always made me think of grass in springtime. Her long, slender legs. There were plenty of other, more specific, details that stood out as well, but none I let my conscious mind linger on. "No, you don't." My response was too flustered and I knew I needed to change the topic. "I guess I can stay up a bit longer, what else did you want to talk about?" I had a sneaking suspicion I knew what it might be, but I hoped I was wrong.

Zoey's lips were curved in an amused smile, but whether it was from my reaction or whatever she planned to say I couldn't tell. Walking around me to finally enter the room, she dropped down on the end of my bed, curling her jean-clad legs under her as she got comfortable. "Stimulation Club, of course. I wanna hear all about it."

Groaning, I closed the door before falling into my desk chair, already feeling a headache coming on. This wasn't a conversation I wanted to be having with my twin sister. "Why are you so interested in it? It's just a silly little club for weirdo artists."

"Because it sounds super interesting, duh. And you said yourself at dinner that it's too hard to explain what it's really about. So I had an idea that--"

"No." I firmly cut her off, not needing to hear the end of the sentence to know what she was about to propose. "We're not doing club activities together." Before she could reply, I pressed on. "It takes nearly an hour to really settle in and get into the right mind space. Call me an old man if you want, but tomorrow morning's class is really important to me and I don't want to stay up late tonight." I left out the part about being uncomfortable doing it specifically with her because it wasn't supposed to be a sexual thing, but it nonetheless made me uneasy.

Zoey pouted slightly before she leaned forward, her eyes glinting. "Is there really no touching? You said that it's all about the senses and touch is such a major one, plus blindfolded college students not touching each other?" One of her eyebrows arched in utter skepticism. "I find that extremely hard to believe."

I frowned, not so much bothered by the question, but rather frustrated that she'd so easily discerned the truth. It meant that it was more likely our parents had come to the same conclusion as well, which would only further cause them to worry about the nature of the club. Not that I was overly concerned they'd ask me to quit or anything. "Promise you won't tell Mom and Dad?"

She grinned back at me. "I'm pretty sure that's all the answer I need, but yeah, your secret's safe with me," she said before making a zipper gesture across her lips.

"There is some touching, but it's not at all like what you're almost certainly imagining. I'm serious," I continued in response to her dubious look. "Both members have to fully consent and then agree on what's allowed, which, for the record, is almost always just the back. It makes for a good place to draw on with a finger."

Looking thoughtful, Zoey slowly nodded her head. "Alright, I believe you. I still think it sounds nice and relaxing. Honestly, it kinda reminds me of nap time back in kindergarten where we'd do that same back drawing thing with the other kids. Made it really easy to fall asleep, although there were obviously no blindfolds involved."

I laughed, but it was nice to hear that she'd made the exact same connection I had. "You're not wrong, I'm usually all but ready to pass out when club ends."

She perked up. "So then--"

"Class. Early. Old man."

Throwing her hands up in defeat, Zoey got to her feet and crossed the room with an amused shake of her head. "Fine, fine, you win. I'll stop pestering my poor, old, brother and let you get to sleep already."

"Same age," I called out right as my bedroom door closed behind her, and I could faintly hear her laughter through it. Still smiling, I rose out of the chair and stretched lightly. It was a bit of a relief she hadn't pressed any harder because it was a somewhat tempting option. Purely for the ease with which it would help me fall asleep, of course. Certainly nothing else. Moving over to my closet, I began to get ready for bed.

The next evening, I was just beginning to prepare to work on my painting when there was another light knock on my door. Already knowing it had to be my sister, I walked over and pulled it open in one, swift motion. "Seriously? You again?" I asked, giving her an annoyed look while making sure to thread a hint of amusement into my voice so she'd know I wasn't being serious.

"Yup! It's your lovely twin sister, back once again. Aren't you the lucky one?" Zoey was smiling, her hands behind her back as she leaned forward slightly, and her enthusiasm almost felt contagious.

Rolling my eyes at her I struggled not to smile back. "What is it this time?"

"You don't have an early class tomorrow, do you." It should have been a question, but from the way she stated it, it clearly wasn't.

"No," I answered hesitantly, suddenly worried that I knew where this was heading.

Her eyes lit up. "Great! Then you totally have time to show me what this club is all about!"

I sighed loudly, rubbing my temples with my fingers. "You're really not going to let this go, are you?"

"Nope!" She was smiling widely, her eyes twinkling in the way they did when she knew she'd already won.

"Fine," I said reluctantly, "but it's going to have to wait. I don't have any blindfolds, although I can probably borrow some from the club."

Zoey's smile got even larger as she brought her hands into view. "Ta-da, look what I brought!"

Blinking at the black fabric in her hands, I looked back up at her. "Why in the world do you have blindfolds?"

"'Cause I made 'em, last night after you kicked me out of your room. It was really easy, I just cut up one of my old skirts that I never wear anymore. They're not perfect by any means, but I checked and you can't see anything with them on."

"Z..."

"What? It's seriously not a big deal, I've got plenty more skirts, don't worry."

That wasn't something I was worried about. It was more that I hadn't been prepared at all to be doing this tonight. I'd fully expected the lack of blindfolds to buy me some more time, but now I had no further excuses. My last hope was that she'd get weirded out by the inevitable, casual intimacy and call it off, although I didn't want my sister grossed out with me either, making it feel like a complete lose-lose situation.

"So. How do we begin?" she prodded, slipping around me and into the room. "Just put the blindfolds on and then start talking?"

Taking a deep breath, I closed the door and turned to face her. "No, we need to settle in and get comfortable before putting them on. Last thing you want to do is trip over something and get hurt while you can't see." I glanced around the room, looking for an ideal location. The obvious answer was sitting together on my bed, but that was clearly out of the question. Besides, maybe if it wasn't actually all that comfortable then she'd lose interest. "I guess we'll just have to sit on the floor."
Zoey frowned at the spot I'd selected but nodded her head. "Right, that makes sense." She dropped down into a cross-legged position which only seemed to further emphasize how skintight her jeans were. "And you sit... in front of me? Behind?"

Moving to sit across from her, I took a similar position that left our knees barely separated. "In front. We're doing a talking-only session, just so you can understand what the club is about." Reaching out, I took one of the blindfolds she was holding out to me, gave her one final look, and then tied it around my head. Everything went dark.

I was immediately surprised at both how well it worked and how comfortable it was. "Wait, isn't this velvet?" It hadn't even crossed my mind that velvet skirts were a thing.

Zoey giggled. "Yeah. I figured it would be the most comfy, not like we'd want denim blindfolds. Plus it's pretty thick, huh? Can't see a damn thing. So, now what?"

"We'll start the same way I did back when I first joined the club, with what we call a shared session. Unlike solo sessions, shared ones are created by both participants, as the name implies. So I'll begin by setting up the scenario and then let you know when it's your turn to add to it. Sound good?"

There was a long moment of silence with no response.

"Did you just nod? Remember that I can't see you."

She burst into laughter in response, gasping for air. "Oh my god, I'm such a fucking idiot. I can't believe I just did that."

"Don't worry about it," I said, smiling. "This is all part of it--getting used to being without vision. If it makes you feel any better, I did the exact same thing my first time."

"Twins, huh?"

"I guess so. Now, you ready to get to it?"

"Yup! Take it away, bro."

I took a deep breath, clearing my mind while also trying to come up with a good, safe scenario. "Alright. Picture a clearing, deep in an ancient forest. We're surrounded by massive trees all around us, reaching up into the bright blue sky overhead. They're pines, and their distinctive, freshly crisp scent fills the nose. Underfoot is a thick carpet of grass, still slightly wet from the morning dew, and scattered around are wildflowers of all colors. Shafts of golden sunlight are filtering down from overhead, while up in the tree branches, but out of sight, birds are singing to each other, their bright, cheery calls blending together to create a beautiful song."

Pausing there, I wasn't sure if I should continue on, or if I'd ended up overwhelming her. "How are you doing, was that too much?"

"What the... It's so beautiful. How did you come up with all of that?"

I could feel my cheeks heating up from her praise, and I was thankful the blindfolds prevented her from noticing. "I've had a lot of practice at this point, both from my artwork, but also thanks to the club. Do you want to take over now, or should I keep going?"

"Keep going, please. I don't want to ruin what you've made."

"Z, you're not going to ruin anything, okay? This is all just for fun. You could say that a neon green cow wearing a pink tutu popped into existence and it would be perfectly fine."

She laughed, which had been my goal--one of her knees lightly bumping into mine. "Okay, okay, I get it. Now can you get this weirdo cow out of here?"

"The cow winks out of existence, returning the clearing back to the way it had been before. Turning around, there's a gently flowing stream behind us. The sound of the water moving over and around the rocks can faintly be heard over the birdsong and occasionally there's a brief glimpse of the shape of a fish before it vanishes just as quickly. The water is so crystal clear that the bottom of the riverbed is fully visible." I cleared my throat. "Alright. Now you give it a try."

There was a lengthy delay, to the point I began to grow worried before she finally spoke up. "A large shadow appears in the stream before a moment later the top half of a mermaid surges up out of the water."

I certainly hadn't been expecting that, but I wasn't going to say anything to interrupt her. More than anything I was curious to see where she was going with this.

"She's got, uh, long blonde hair and... purple eyes. Her skin is flawless and pristine and... and she's wearing a little tiny shell bikini over her gigantic titties."

I raised an eyebrow, even though I knew she wouldn't be able to see it. "Really? Giant tits?"

"Don't guys like massive boobs?"

"This isn't about me, Z. You should describe what you want, not what you think I want."

She sighed loudly. "What if I like huge boobs?"

"...Do you?"

"Not at all."

"Don't make me bring the cow back." It was a pretty weak threat, all things considered, but it pulled a giggle out of her.

"Okay, fine. The mermaid's boobs shrink down until they're about my size."

"That's not terribly helpful, Z. It's not like I can just instantly imagine what that looks like." It was a blatant lie. The mermaid in my head totally had my sister's exact boob size now.

"I feel like I should be vaguely offended at that."

"You want your brother perving on you?"

"Well, no, but you noticing I have a nice pair of tits isn't the same as you perving on me."

"I'm pretty sure brothers aren't supposed to find their sister's boobs 'nice.'" To be fair, Zoey just happened to have what I considered to be the perfect breasts. Not so small she didn't have any cleavage, but also not so large that they wouldn't make a nice handful. It was a complete coincidence, of course, and certainly nothing more.

"I mean, if you need a reference then just pull up your blindfold for a sec and take a quick look."

What? Had she seriously just suggested that I should look at her boobs? I was so taken aback by her words that it took me a moment to realize the silence between us had reached the point of being awkward. "Err..."

"I'm joking, jeez. You didn't actually do it, right?"

"No!" I said, possibly a little too quickly and defensively. The fact that a part of me had wanted to made me feel awful. This was exactly what I'd been afraid of with trying to do club stuff with my sister. Horny conversations with the girls in the club were fun and exciting, but with Zoey, it couldn't be the same.

"Stupid mermaid," she muttered. "I knew I was going to ruin it."

I could hear her taking off her blindfold so I did the same, blinking rapidly as my eyes adjusted to the light in the room. I'd need to remember to dim them next time, something that had completely slipped my mind earlier. To my surprise, Zoey looked seriously upset--like borderline tears in eyes sad.

"Z, come on, you didn't ruin things. If anything, you did pretty well for a first-timer."

My words seemed to at least somewhat help, but she still looked quite down. "I could have done better though, and we didn't make it even close to an hour since I barely came up with anything at all. Compared to your clearing, my mermaid also seemed so... bland. I think that's why I went for the giant tits, really. What else could I have done to make her, I don't know, pop more."

"Hmm, lemme think for a moment." The question was really how much detail to go into, and with a half-naked fish woman that could be challenging. "Okay. First off, you said she had blonde hair, but you left it at just the color. One option would be to describe how she was wearing it, although I'd actually rely on you for specifics around that since I'm not at all familiar with women's hairstyling. You also focused on her upper half, but you could have mentioned how the sun was glinting and glistening off the scales that were just under the surface of the water."

"Oh, nice. And then with the bikini, instead of just mentioning the tiny shells I could have gone into more detail, like saying it was a red, string bikini and that the white seashells were so tiny they only covered her nipples."

I flushed as the image filled my mind. "Yes, that paints a much more vivid picture, for sure."

"See! I knew you liked boobs." Now she was smiling again, which was nice, although I could have done without the continued teasing.

My face was only getting hotter, and I knew I needed to change the topic. I was also making sure to keep my eyes focused firmly on her face. "So now you know everything there is to know about Stimulation Club. Not all that fancy in the end, is it?"

Zoey made a soft humming noise in response, almost acting as though she didn't believe me for some reason before turning to look over at the easel in the corner of the room. "By the way, what's up with that painting?" she asked. "Feels like it's been in mostly the same state for weeks now which isn't usual for you."

A part of me was surprised she'd noticed, especially considering that other than today and yesterday she rarely came to my room. "Oh... It's supposed to be my main piece for my painting class, kind of like a final test that you spend all semester working on."

She frowned slightly. "Wait, isn't that deadline only a few weeks away?"

"Yeah, well, I might have set my goal a little too high." I chuckled, although the sound was more self-pity than amusement. "I'm probably going to have to end up doing something else if I don't start making some serious progress soon."

"What's it supposed to be? Other than a woman. I think. Maybe?"

Doing my best not to look too pained, I tried to come up with a good explanation--mostly because it was rather embarrassing to talk about, especially with my sister of all people. "You've got it, for the most part. I was... trying to capture the essence of beauty, kind of like my own version of Botticelli's The Birth of Venus." I only made the reference because I knew she'd remember the painting from when our parents had taken us to Italy on vacation the previous year. "It's obviously proven to be a bit more challenging than I expected."

"I'm sure you'll be able to pull it off," Zoey said with a confidence I appreciated, but couldn't share. Rising to her feet, she dusted off her jeans before continuing. "I'll get out of your hair now and let you get back to it. I'm sure you don't want to spend any more time with your annoying sister than you have to."

I frowned. "Well, that feels a bit unfair."

"Just kidding," she said with a wink. "I know you love me."

My mouth flopped open and closed several times, but before I could formulate a response she'd already breezed out of the room--a cheeky grin plastered all over her face. It took me several minutes after she'd left to regain my composure and get back into a headspace where I felt like I was ready to give the painting another shot. Maybe tonight would be different.

It wasn't.

~ ~ ~ ~ ~ ~ ~ ~ ~ ~



The following evening ended up being entirely sister-free, and I couldn't make up my mind if I was sad about that or slightly relieved. Once again, I failed to make any meaningful steps toward completing my painting--leaving me feeling like it really was well past time to try and come up with something else entirely instead. Deciding to give it one, final week, I called it a night, hoping that Stimulation Club might finally provide me the breakthrough I so desperately needed.

Session 2



I'd just begun to think Zoey wasn't going to show up for a second night in a row and was about to try giving the painting yet another shot when her familiar, gentle knock sounded on my door. Grateful for any excuse not to continue failing, I quickly walked over to let her in. The first thing I immediately noticed was that my sister had changed up her wardrobe. While she was still wearing a T-shirt, gone were the skintight jeans, replaced instead with a double-layer plaid skirt that dropped to just above her knees, worn over a pair of sheer tights.

"See, told you I had more skirts," she said in amusement, and I lifted my eyes to find her smiling.

"Uhh, right," was the only response I could come up with, completely unsure of what to say. A part of me wanted to take a longer, second look, but I knew I shouldn't be staring at my sister's legs. "What can I do you for?"

Zoey slid past me, the hem of her skirt lightly brushing against my leg before I stepped back to give her more room. "Okay, so, I haven't been able to stop thinking about the shared session we did the other day. I can't help but feel like it was... lacking."

I blinked in surprise before pushing the door closed and turning to face her. "What? I thought you enjoyed it. Didn't you say that it had been beautiful?"

"No, no, it was, but like... it was all purely visual. I know you mentioned things like the smell of the trees and the sounds of the birds, but I struggled with those parts. Maybe my imagination just sucks, though."

"I'm pretty confident your imagination is just fine." Her mermaid flashed unbidden in my mind before I banished it. "I think I understand what you're talking about, though. Sometimes in the club, we'll play some background music like waves crashing to help with immersion, and I've also seen some people using stuff like scented candles too."

"See, both of those sound like fantastic ideas. But I also feel like you've been really downplaying the whole touch element. That's why I've decided that tonight we're going to be doing a shared session with touching allowed."

My eyebrows nearly hit the ceiling. "Z, no way. That's not going to work."

"Oh come on, Zack. Stop being such a spoilsport, it's just our backs for fuck's sake!"

"No, no, that's not it," I said, shaking my head. "When touching is on the table, it's always a solo session, where the person describing everything sits behind the other. If you did a shared session, where both people faced each other and were touching the other person, it would get awkward. Fast."

"Ah."

I breathed a sigh of relief, glad she understood why her plan wouldn't work out.

"Well, in that case, all we have to do is take turns doing solo sessions, except they'll blend together as if it were a shared session. Simple."

Opening my mouth to shut down that idea as well, I gradually closed it instead as I slowly processed what she'd proposed. It was an incredibly simple idea, and yet, for some reason, I'd never seen or heard of anyone doing it at the club. "Huh. I guess that could work, actually."

"Great!" She was smiling again, her earlier frustration seemingly faded away. "One other thing, before we start. Can we please sit on your bed today? The floor was crazy uncomfortable last time."

"What? Uhh, sure, I guess?" There wasn't anything inherently wrong with her being on my bed, and if she was the one proposing it then I assumed she was comfortable with it as well. Walking over to my dresser, I grabbed the blindfolds Zoey had left behind as she dropped down onto my bed with a contented sigh that felt a little over-exaggerated.

"Oh yeah, this is so much better." She even went so far as to bounce in place a bit, as if she were still a child.

I was just thankful to see she hadn't taken the same cross-legged position as the other day--her legs instead curled under her and a bit off to one side. Even so, her skirt was riding up much higher than it normally would, showing off a lot of leg.

"You should probably go first again," Zoey said as I joined her at the bed and held out one of the blindfolds. "That way I can learn from the pro before giving it a shot of my own."

Laughing, I climbed onto my bed and moved to sit behind my sister--it wasn't a surprise, but this really was far more comfortable than being on the floor. "Not sure I'm a pro by any means, but yeah, I'll take the lead again until you're ready to give it a try."

We each tied our blindfolds on, and then I was left sitting there wondering what the fuck I was supposed to do next. At the club, I'd never actually been the one to lead a solo touching session. In fact, I'd only ever done one once, and I was pretty sure my partner had been very into me because she'd made the session incredibly erotic--leaving me with a raging hard-on by the end of it. That certainly wasn't an option with my sister, not that I had boobs to press into her back.

"Zack? What's up?"

"Sorry," I quickly replied. "Just trying to think of a good setting and coming up blank."

"Just use the clearing from last time, then. I don't mind if it's not completely new, and besides, it'll probably help me to have some familiarity."

I'd been hoping to avoid doing a repeat since it seemed a little boring, but without a better idea, I supposed it would have to make do. "You're standing back in the clearing, surrounded by trees on all sides, except this time it's cloudy and overcast." Hesitantly, I reached out and placed the palm of my right hand against Zoey's back.

She jumped slightly, sending a tremor through the bed. "Oh shit, that scared me."

"Sorry." I almost pulled my hand away, but kept it motionless where it was for now.

"No, no, that's the entire point of this. It's just... a bit more than I was expecting. Never had anyone touch me while I was wearing a blindfold before, it really does change things."

"Sure does. You good to keep going or having second thoughts?" I honestly wasn't sure what I wanted her answer to be.

"Keep going, of course! I'm all good now."

Taking a deep breath, I continued by dropping my hand to her lower back before slowly beginning to trace it upward. "Your eyes travel up the trunk of the tallest tree until you finally reach the top." My hand reached the collar of her shirt as I finished speaking, but I left it there for now instead of moving up to her neck. "The clouds overhead promise rain, but they're not the dark and ominous kind that would herald a large storm. All around you, the leaves of the trees begin whispering as a gentle wind blows through them."

I wasn't very confident about this next part, but I began to gently blow air on her neck, using my hand as a guide since I had no other way of making sure I was hitting the right spot.

"Ooo, that's a nice touch!"

"Shh," I whispered, before taking another breath and returning to the blowing. I'd been worried she'd be weirded out by this, so it was nice to get some confirmation that it was working. Of course, I couldn't keep blowing while talking, so I only did this for about a minute longer before moving on.

"As the wind dies down somewhat, you feel the first drops of rain on your arms." Once again, I was worried about this part, mostly because with the blindfold on it was impossible to know exactly where her arms were. I think I missed the first time, but then on my second attempt, I felt my finger lightly bump into her--as if I were pressing a key on a keyboard.

Now that I had the position locked in, I continued to slowly tap on her arm, bringing my other hand up to join in on the opposite side. "The rain slowly picks up, but since it's nice and warm out it's comfortable and relaxing." I began drumming my fingers up and down both of her arms, in addition to moving down her back occasionally. "All around us, you can hear the soothing noise of the rain pattering about--against the trees, the rocks, and even the river behind. Far off in the distance, you even think you faintly hear the sound of a single moo."

Zoey giggled, and I couldn't help but smile at her reaction to the silly little callback from the first session.

"By now, the wind has picked back up and you can hear the trees swaying back and forth, their branches occasionally clacking together. The rain is coming down harder than ever, completely drenching you but in a way that feels more freeing than anything else." I switched from tapping on her arms to simulate raindrops to instead loosely wrapping my hands around her arms before sliding them up and down. It was supposed to feel something like water running all over her, but I wasn't sure it was all that accurate.
Simultaneously, I stopped talking to blow on her neck once more, wanting to get the wind involved again as well as taking a moment to rest my voice. For her part, Zoey was making contented noises and not complaining about anything, so I figured it must be working out well enough. Unfortunately, after doing this for several minutes I ended up overestimating how far down her arms I could go, and before I realized it, I found myself all but kissing the back of my sister's neck.

I immediately pulled back in a panic, my hands releasing her arms as I stammered out an apology. "Shit, I'm so sorry. I didn't mean to do that." The entire time, I couldn't get the feeling of my lips on her skin out of my head.

"Zack, chill out," she said, once she finished laughing. "I know it was an accident, but now I also feel like I have a whole new understanding of what it means to be kissed by the wind."

My cheeks felt like they were on fire. "I am so sorry. We can call it a night if you want."

"What, and skip my turn? No way. Let's swap positions."

I could hear her rustling my blankets as she shifted in place, presumably turning around, so I followed suit. A moment later, Zoey's hand slapped into my back, although it wasn't hard enough to hurt or anything.

"Oops, there you are. In retrospect, I probably should have just taken a peek to see where you were instead of nearly punching you." Her hands shifted up to my shoulders before giving me a gentle squeeze. "You good to go?"

"Yeah, sure." This would help get my mind off what had just happened, at the very least.

"Okay, let's see. As you stagger backward in surprise from your recent transgression, a pair of hands catches you from behind before you end up tumbling backward into the river. Can you guess who they belong to?"

I blinked in surprise. "Uh, Z? Usually the person on the receiving end doesn't interact with the descriptions."

"Right, I get that, but it's also a little boring. Can't we try it out this way and see?"

I wasn't entirely sure how I felt about her proposal, mainly because it felt like a step closer to role-play than simply describing a scenario, but I also didn't want to just shut her down when she was clearly interested in trying this out. "Um, I guess we can give it a shot. I imagine the hands belong to the mermaid then if the person is already in the river?"

"That's right!"

She sounded so happy I found myself smiling.

"Glancing over your shoulder, you see the familiar form of the mermaid behind you. This close, you're able to see the worry in her purple eyes. She tells you that there's a cave a short way downstream where you could make a fire and get out of this storm before it grows any worse. If you're interested, she even offers to swim you there."

I was once again caught off guard, not at all used to interacting with a fictional character being described by someone else during a session. A part of me was tempted to say no, just to see what she would do if I messed with her planned narrative, but I decided to go along with it for now. "Sure, I guess that sounds nice."

"The mermaid tugs you backward into the stream." Zoey pulled me backward, into her, nearly causing me to jump in surprise at the abrupt and unexpected motion. "You're already so soaked through from the rain that you don't even feel the difference as the surprisingly warm water of the river engulfs you. Before you can sink, she tightly wraps her arms around you, holding you against her, and then she begins rapidly swimming down the river."

I sucked in a quick hiss of air. It wasn't so much that my sister was now hugging me from behind--although that was certainly a part of it--but more that I could distinctly feel her breasts pressing into my back. A part of me was impressed at how much better Zoey was doing compared to her first session, but at the same time, I was already growing worried about this degree of physical contact. Before I could say anything, she continued her scenario.

"It doesn't take long at all before the dark mouth of a cave comes into view at the side of the river. Without hesitating, the mermaid swims you inside. In the pitch blackness, you're unable to make anything out as she continues forward before eventually coming to a stop. A moment later, there's a flash of bright light as a pile of wood on a small island suddenly bursts into flames."

"Mermaids can use magic?"

"This one can, now shut up!"

I snorted a laugh and let her continue, still a bit cautious but enjoying the experience for now.

"Releasing her firm grip on you"--Zoey did exactly that, pulling away from me and shifting her hands back up to my shoulders--"she lifts you out of the water and sets you down next to the comforting warmth of the crackling fire. Watching from the water, she comments that you'd dry off faster if you removed your clothes."

Yet again, I was immediately flustered by my sister's words. It was just a mental exercise, and it wasn't like my character stripping down meant that I'd also do it myself, but the concept was discomforting. "I'm not stripping."

Zoey giggled softly behind me. "The poor mermaid looks saddened by your rejection. Rising up a bit so that she's leaning halfway out of the water, she begins to squeeze the water out of your clothes as best she can while you're still wearing them."

Her hands began to slowly work their way down my arms, not so much in a squeezing way, but rather much more like a massage. It was immediately relaxing, and I felt myself sinking into the bed as Zoey worked the stress I hadn't even been aware of out of my body. By the time she'd reached my wrists, her chin was on my shoulder--her soft breathing tickling my ear--and our bodies were molded together once again. I'd known she'd been taking some physical therapy classes on the side as more of a hobby than anything else, but I hadn't realized just how damn good she'd gotten.

"There. All dry now," she said softly.

I expected her to say or do something else since she was the one in charge of this session, but Zoey seemed perfectly content to leave things as they were. I almost would have thought she might have dozed off if I couldn't feel her shifting around slightly every once in a while. As comfortable as I was, I also couldn't ignore how close we were, and how confused it was making my body. If it had been anyone else, I would have been tempted to start flirting back, but not with my sister.

"Thanks for that," I eventually said, breaking the silence. "But if the only way into this cave is by swimming, then aren't I going to end up getting just as soaked as I was before when I try to leave?"

"Well, I guess you're just trapped here with me forever then, now aren't you?" Zoey whispered into my ear. Her voice had dropped slightly below its normal level, and the words sent a shiver down my spine. The raw sexuality laced through them had my cock hardening in an instant.

"And scene!" I desperately called out, pulling forward and shifting off the bed to stand up.

"Aww, what? And I was going to have her kiss your neck too."

I briefly regretted cutting it short before a rush of shame flowed through me. Wanting to feel my sister kissing the back of my neck was wrong, even if it was just part of a silly joke from earlier. Pulling off my blindfold, I had to shield my eyes from the sudden brightness of my room--I'd forgotten to dim the lights yet again. Once they'd somewhat adjusted, I turned to look at Zoey and immediately had to look away. She was still in the same position she'd been in while cuddled up against my back, and since her knees had been spread around me, it had caused her skirt to ride up far enough that I'd caught the briefest glimpse of her crimson panties. Fortunately, Zoey was still blinking her eyes, so I hoped she hadn't noticed what I'd seen.

"So? How'd I do?" She bounced to her feet, a nervous half-smile on her face.

As I was still trying to get my brain sorted out, I settled on a cop-out answer to buy myself some more time. "How do you think you did?"

"I mean... pretty good, right? Obviously, I can't compare with you, but I thought it went well. And I really enjoyed adding the touching! It made the whole thing so much more intense."

She wasn't wrong there, although I still wasn't sure that level of intensity between us was a good thing. "You did great, better than some people in the club, honestly. And after that massage, I'm completely ready to pass out. It was seriously amazing, Z."

Before I realized it, she'd launched herself at me, her arms wrapping around me in a tight hug as--for the third time that night--I found my sister's body tightly pressed against mine. "Thanks," she mumbled into my chest, her head nestled under my chin. "I've been practicing a bunch, but I was worried you might not like it."

The faint scent of peaches filled my nose--either her perfume or her hair conditioner, I honestly couldn't tell--as I cautiously returned the hug. We'd been close growing up, but the recent levels of physical contact between us were very much a new thing. Zoey was clearly comfortable with it, which meant it was probably all on me for making it weird. Especially considering that it was very nice.

Zoey stirred slightly in my arms, and, assuming that she wanted to pull back, I released her. She did loosen her grip on me and take a half-step back, but, to my surprise, she then went up onto her toes before pressing the briefest of kisses on my cheek.

"Only fair that you get a kiss too, even if it's just from your lame sister and not a sexy mermaid," she said, dancing backward--eyes twinkling playfully--before giving me a wink.

I nearly said that I preferred it that way before barely managing to catch myself, leaving my mouth hanging open.

"I'll leave you to it then, see you tomorrow night!"

And then she was gone, my bedroom door swinging softly shut behind her.

It took me several minutes to move from where I'd frozen in place, the faint touch of my sister's lips still burned into my mind. She'd obviously just been teasing me after my earlier slip-up, but as I made my way over to the easel to give the painting another shot, I found that I couldn't help but look forward to tomorrow.

Session 3



"Oh, nice! She's got boobs now!"

I blinked several times, completely caught off guard as Zoey let herself into my room without knocking. Or, at least, I didn't think she had. I'd been in the middle of working on an essay for my creative writing class so it was entirely possible that I'd missed it. Turning around in my chair, I found her examining the progress I'd made on the painting last night, which helped her statement make a whole lot more sense.

She was wearing a different skirt tonight--to continue the running joke I imagined--although this one was dramatically shorter. It only fell to the middle of her thighs, and while it was probably fine to go out in, I knew for a fact she hadn't been wearing it at dinner--neither Mom nor Dad would have let it go without some form of comment. As for me, well, with the amount of leg it revealed and how much attention it inherently focused on what was barely being concealed, I would have loved to give it a nice, long ogle.

If anyone other than my sister had been wearing it.

It took a surprising amount of effort to rip my eyes upward to the back of her head as I walked over to join her, and I was immensely thankful she was too focused on the painting to have noticed my inappropriate gaze. Given that she'd obviously changed into it before coming to my room, I could only assume she was trying to make me flustered which in turn made me want to do the exact opposite. I certainly wasn't going to wonder if I'd manage to catch another glimpse of her panties or what color they might be tonight.

"Yeah, I feel like the pieces are starting to come together a bit, although it's still going a lot slower than I'd like," I said, looking at the spherical shapes I'd most recently added with a critical eye. Calling them boobs at this stage was a bit generous since the painting was still entirely lines and nothing else, but it was progress, and I couldn't complain about that.

"Hmm, I can't quite explain it, but something about them feels... off."

I glanced over, surprised at how seriously she seemed to be taking this. Her finger was resting thoughtfully on her lips and my train of thought was momentarily derailed as I found myself staring once again. Zoey's lips were certainly a part of her I'd never really paid much attention to, but now I couldn't help but notice how soft and shiny they looked. Kissable was the perfect descriptor, and yet, at the same time, absolutely the worst possible one.

"Well, they're obviously still a work in progress," I slowly replied. "Once I'm finished they'll look much more natural."

"Right."

The doubt in her voice was unmistakable, but before I could say anything else she continued.

"It's just..." Her cheeks flushed ever so slightly. "Have you ever had any, you know, hands-on experience?"

I felt like my brain had short-circuited. Unless I was crazy, my twin sister had just asked me if I'd ever touched a pair of tits. It was my turn to blush, and I was very thankful we were both looking at the painting and not each other. "Um. Not exactly, but I've seen plenty."

"Without clothes on?"

"Yes." My face was heating up.

"So porn then."

"Seriously, Z?"

"What? Nothing wrong with watching porn."

I shot her another quick glance and was relieved to at least see that she also appeared to be extremely embarrassed. How the hell had we even ended up on this subject, and why were we still going? "Fine. Yes, from porn. Are you happy?"

Zoey shook her head slightly. "No, that's not what I'm getting at. That's exactly what Stimulation Club is all about, isn't it? How are you supposed to create realistic-looking boobs from sight alone?"

I opened my mouth to tell her how ridiculous she was being, only to close it again as I realized that her point wasn't entirely invalid. At best, I was simply mimicking what I'd seen on the internet. Sure, it would work, but it could also be so much more, and the entire point of this painting was exactly that. Of course, there was one, absolutely massive issue.

"Okay, I'll concede that you have a point, but it's also not exactly something I can just solve. I don't have a girlfriend, and last time I checked, going up to a woman and asking if you can fondle her breasts for research is more likely to get you slapped than anything else, if not sent off to a jail cell."

She laughed. "Yeah, no, definitely don't do that. Hmm, there's no one at the Club who might be up for a relationship? A good-looking guy like you has to have drawn some attention."

Good looking? If I wasn't already blushing then I certainly would be now. Was she being serious or just teasing? I couldn't tell. Ignoring it, I focused on the first part of what she'd said. "I mean, there's plenty of attractive girls there who I'd love to date, yeah, but not in the timeframe I have, not to mention that feels like an absolute dick reason to hook up with someone."

"True, and time is certainly an issue. No way I'd let some dude I just started seeing feel me up right away."

The last thing I wanted to be thinking about was some stranger with his hands on my sister.

"I guess that leaves us with only one possible option then."

I sighed. "Yup. It's unfortunate, but I'll just have to do the best I can given my lack of real experience."

Zoey finally turned away from the painting to face me, an amused expression all over her face. "Really?"

"Yes?"

"I happen to be a woman, you know."

"I... am aware of that, yes," I said, not understanding why she felt the need to point out something so blatantly obvious.

"And I thought we'd already established that I have a pretty awesome pair of boobies."

My eyes dropped down to follow the motion as she cupped her boobs over her shirt with both hands before I forced myself to look away. A moment later, the pieces all slammed together as I realized what she was suggesting. I staggered backward and dropped down to sit on the foot of my bed. It had the unfortunate side effect of putting my head directly at boob level, and since she was still cupping them, I could easily make out the outline of her bra through her shirt.

Lifting my eyes back up to her face, I felt a flicker of annoyance bloom to life inside me as I took in her smile. "Seriously? I can't believe I fucking fell for this."

Zoey's face immediately fell. "Wait, what? I just--"

"Nice job. I actually thought you were trying to help for a moment there, but I should have known you were just looking for a way to screw with me."

"No, that's not--" She cut off on her own, biting her lower lip before she rushed out of the room.

It took all of a minute of sitting there in silence going over everything that had just happened before a tidal wave of shame crashed over me. Without even needing to think about it, I threw open my door and rushed out of my room, making a direct beeline down the hall before coming to a halt outside Zoey's room.

"Z," I called out, knocking on her door. "Let me in, please? I'm sorry."

"Go away." The words were faint, but it was impossible to miss the tears in her voice.

The last time I'd made her cry had to have been back when we were still kids, and I hated it just as much now as I had back then. Kicking myself for being a complete and total idiot, I stopped knocking as I tried to think of some way to remedy the situation. Of course, there wasn't all that much I could do other than apologize, and it wasn't hard to understand why she didn't want to talk after how insensitive I'd been. A part of me still couldn't believe what she'd offered, but the blame was entirely on me for jumping to the wrong conclusion.

"I'm sorry. I never meant to hurt you," I said to the door. "I didn't think there was any way you were serious, but I should have checked with you before automatically assuming the worst. Especially when it's you. And look, I can't blame you for hating me right now, but if you want to talk, I'll be waiting in my room." There wasn't anything more I could do, so I turned and started walking away, feeling very much like the jerk I was.

A loud sniffle from behind stopped me in my tracks just a few steps down the hall. "You mean it?"

I turned around to see her standing in the doorway--eyes red, but with a cautiously hopeful look in them. "I do," I quickly replied, nodding. "It just... didn't occur to me that you'd actually be willing to offer something so... extreme."

She smiled gently, and I breathed a soft sigh of relief as most of the lingering pain faded from her face. "It was a bit crazy, huh?"

"A little bit more than that, but yeah."

"Well, come on in then."

She stepped backward, out of view, and I hesitated for a moment before I turned back around and walked into her room. As I closed the door behind me, I realized how long it had been since the last time I'd been in Zoey's room. While she'd occasionally drop by mine, the opposite wasn't true. In fact, it had to have been at least since before high school when I'd last been here. As I glanced around, most things seemed to have stayed roughly the same, although there were several distinct differences.

The very first thing I noticed was the smell. It was a soft, vanilla-like scent, mixed together with some kind of flower that I instantly associated with Zoey. I'd never really thought about it before, but it was clearly her perfume and it was absolutely delicious. The second thing I noticed was how impeccably clean the room was. Not that mine was messy by any means, but my sister's floor was entirely absent of a stray shirt or shorts, unlike my own. There were several pictures hanging around the walls, mostly of her and her friends, but I was surprised to see one of the two of us on the wall opposite her bed. It was from a rafting trip we'd gone on together a few years back, and we both looked so ridiculously happy that I couldn't not smile looking at it. From there, the room was mostly as I remembered it, although I noted that she'd moved to a dual monitor setup with one of them vertical--a coding thing from my understanding of Comp Sci--and also that her bed was absolutely covered in pillows and plushies, to the point where I wondered how she could even sleep in it.
"Whatcha think?"

"Oh." I felt like I'd been caught snooping around, which was silly since she'd invited me in. "It's nice, and it uh, smells amazing. Where do you sleep, though?"

Her lips curved up into a broad smile as she laughed. "On my bed, silly." Stretching her arms out, she fell backward onto it, sending pillows of all shapes and sizes tumbling off the sides. "It's super cozy and I love to cuddle with things. I don't hate you, by the way."

The abrupt shift in topic back to our earlier conversation caught me off guard, but I breathed a soft sigh of relief at her words.

"Not something I imagine you ever expected to hear from your sister of all people, huh?"

"It really wasn't." I shifted nervously in place by the door.

"I did mean it, you know. I'm willing to help you out, even if it's a bit crazy." She sat up amongst the pillows, one of them hugged tightly against her.

"I appreciate that, but... Z, you're my sister."

"Right, but in a way, that'll make things easier, won't it?"

I cocked my head a little, confused. "Easier? How so?"

"Well..." She looked away from me, clearly embarrassed. "Since we are related, that means it'll be a true learning experience. Like, it's not going to be sexual at all."

I very much wanted to agree with her, but deep down, a part of me knew that no matter who they belonged to, there was no way I wasn't going to get at least a little turned on by playing with a pair of, let's be honest, extremely nice tits. As if to prove my point, I could already feel myself getting a little hard at the thought of what we were discussing.

"I think I even have an idea how to make it as least uncomfortable for the both of us as possible."

"Oh?" I was reluctant to continue down this path, but also curious as to what she had in mind.

She nodded. "We do a solo session, where you're obviously the one doing the touching, except"--she raised a hand, one finger pointing up--"I'm the one who's describing everything. It's a big mix-up, I know, but this way I can detail exactly what I'm comfortable with, and then you can follow along assuming you are as well."

It was honestly an impressively well-thought-out plan, especially since I hadn't at all considered tying it into the club. The fact that we'd both have a say in exactly what happened was also encouraging because I knew there was no possible way I'd ever feel comfortable doing a session where I was describing myself groping my sister. Not that it would change what I was still doing.

"But they're still your..." I couldn't even finish the sentence.

"Boobs? Yeah, not a whole lot we can do about that, but I'll describe the scenario as someone else, to help distance it. Your imaginary girlfriend, for example."

Sighing, I considered it. I was still concerned that she was pushing herself much too far for something that really wasn't a huge deal, but, at the same time, worried that if I turned her down it could possibly damage our relationship. She was the one volunteering, after all, and the only reason I was hesitating was because of who she was.

"Alright," I said slowly. "If you're really set on this then we can give it a try, but the moment either of us gets uncomfortable we end it, no questions asked, okay?"

Zoey visibly swallowed, then nodded her head.

"Oh, and no more mermaids, please. I'm not into fish people."

She laughed brightly, her eyes shining. "Alright, alright. You can date a normal, human woman. Come, sit." She patted the bed behind her.

"Oh." Everything suddenly felt very real. "We're going to do it right now? I didn't bring the blindfolds with me."

"That's fine. I'll turn off the lights and then we can also close our eyes. Should be basically the same thing, right? Or, if you really want, you can go run and grab them."

Any lingering doubts I had faded away--she was clearly committed to this. Which only left getting into position. I slowly made my way over to the side of the bed, eying the spot behind her. In the process, I couldn't help but notice yet again how high her skirt had risen up, but at least the pillows helped to cover her. Climbing onto her bed, I pushed two pillows out of the way before settling into a cross-legged position. Leaning forward, she reached out and flipped the light switch on the wall near the head of the bed, giving me a brief flash of her panty-clad butt right before the darkness engulfed everything.

They were blue today.

Closing my eyes despite the room now being nearly pitch black, I did my best to not focus on what I'd just seen. For her part, Zoey settled back into place in front of me, scooting backward until she softly bumped into me.

"Alright, you ready for this?"

"Was... that a Space Jam reference?"

"...No? Okay, yes. I was just trying to lighten the mood a bit."

I laughed. If she wasn't going to make a big deal out of this and was as comfortable as she seemed, then there was no reason for me to be freaking out about it either. Sure, it was a little weird, but she was right, it was just some harmless research. "Take it away then, I'll follow your lead."

"Got it." Zoey took a deep breath and then she began. "You settle down on the bed behind your girlfriend. It's the first time she's invited you over to her house and you're nervous, but also excited--especially since she brought you directly to her bedroom. The two of you have been dating for just over a week now, and you're both ready to take things to the next level."

The amount of backstory caught me off guard, but it loosely fit with the club concept and it wasn't like I was going to interrupt her--not when I was so curious to see what she had in mind.

"Since you're still a little nervous, you cautiously reach out and place your hands on her back to start things off."

She paused there, and it took me a moment to remember I was supposed to be mirroring what she was describing. It was strange to do a session like this, but I did indeed hesitantly reach out to place my hands on Zoey's upper back.

"Sliding your hands upward, you wrap your fingers over her shoulders and then use your thumbs to give her a bit of a massage."

I followed the instructions once again, laughing softly. "Why am I getting the feeling that you just wanted me to give you a massage now?"

"Hush. None of this has anything to do with me. Your girlfriend rolls her shoulders slightly, and asks you to use a bit more pressure to work out the knot in her left one."

It was extremely challenging for me to go along with the concept that I wasn't doing all of this with Zoey, especially because she did have a rather tight knot in her left shoulder. Working it with my thumb, I eventually managed to loosen it up, earning a contented sigh from my "girlfriend."

"Feeling emboldened, you drop your hands back down to her upper back, before beginning to creep them around her sides. Through her shirt, you can feel her bra, and the knowledge that you'll soon be touching her boobs for the first time fills you with excitement. You've seen them so many times, and now you'll finally be able to find out what they feel like."

I had to swallow at the description as my hands drifted down her back. When my fingers brushed against the sturdy fabric underneath her shirt that was her bra, I froze for a moment, needing to shift uncomfortably in place as my traitorous cock decided it was time to start getting excited. I was not going to be the one to make this weird. Pushing on, I shifted the placement of my hands so that my fingers slipped between her arms and her sides.

Zoey paused there for what felt like an eternity, but couldn't have been more than a minute at most. As I waited for her to tell me what to do next, I wondered if she might be preparing to call off this insanity, and I was surprised to find that I suddenly very much did not want that to happen. I wasn't entirely sure how to feel about that.

"Your girlfriend lifts her arms slightly away from her body and then falls backward into your arms, causing your hands to move around to her front in a semi-hug as you finally get the chance to grope her."

It played out exactly as she described it. In one instant, my hands went from the relative safety of Zoey's sides to a place no brother should be touching as she fell back into me and I almost instinctively wrapped my fingers around her boobs as if to catch her. I hadn't been expecting the sudden motion, and I barely managed to shift my head to the side to avoid a direct collision with the back of hers. It left my chin over her shoulder and the faint peachy scent that I now assumed must be her conditioner mixed together with the fragrance of her perfume and tickled my nose.

Before she had a chance to continue to describe what happened next, my fingers were already lightly squeezing, feeling the shape of her bra through her shirt. Zoey's boobs rested in my palms perfectly, almost as if we'd been designed to perfectly fit together like this.

"Tentatively, you begin to feel your way around, running your hands all over her tits to learn the shape and size of them."

I didn't need to be told twice. Shifting my hands down, I cupped her boobs from below--or at least, I attempted to, but her pesky bra got in the way of being able to get the grip I'd wanted. I ignored the soft giggle that escaped my sister's lips and shifted my hands in opposite directions along the band before circling back up around the sides. Slowly working my way around their circumference, I came to a halt as my fingers reached the neckline of her shirt--brushing against her skin.

Throughout all of this, Zoey had remained silent, other than the sound of her breathing which seemed a bit heavier than normal. It made sense, though, I could only imagine the thoughts that were flashing through her mind as she grappled with the fact that her brother was groping her like this. Pausing, I waited for her to give me any further instructions. After an exact count of a slow minute in my head without her doing or saying anything at all, I decided I'd just continue following the last thing she'd said.

My fingers slipped off of the cloth and fully onto her skin as I continued their circular trip--the tips bumping into each other as they slowly descended into her cleavage. I came to a halt once again as I reached the base of her v-neck, my hands all but entirely palming her boobs at this point. Given the position, it was utterly impossible not to give them another squeeze, although this time I did so with slightly more force--trying to get a better understanding of exactly what they felt like.

Zoey's silence finally broke, except it was only another--presumably nervous--giggle in response to my action. At this point, I wasn't entirely sure what to do next. I was already vastly more familiar with my sister's boobs than I'd ever expected to be, and short of having her take off her shirt or even her bra, I didn't think I'd be able to get all that much more out of this. At the same time, it was strangely comfortable to share this casual intimacy with her, and I found myself not wanting to let her go.

I wasn't even really thinking as I brought the index and middle fingers of both my hands to the peak of her breasts and began moving them in a circular motion where I guessed her nipples were. It wasn't until a few moments later when I heard a soft exhale that sounded suspiciously like a moan--enough that it caused my now completely hard cock to throb in my pants--that I realized just how undeniably sexual the situation had become.

As much as a part of me wanted to continue, to see if I could get a true, full moan out of her, I forced my fingers to stop as I shifted backward, clearing my throat. It was understandable how we'd gotten here, but it was time to put a stop to it before things ended up going too far. Regretfully. I gave her amazing boobs one, final squeeze, and then pulled my hands free.

Zoey didn't immediately say anything about my decision to stop. I could feel her shifting around slightly in front of me in the dark, and from the sound of things she was breathing even more heavily than before. "Well. That was certainly an experience," she eventually said, breaking the silence that had settled over us.

"I'm sorry."

"Please don't apologize." Her reply was surprisingly sharp, catching me by surprise. "You're making a bigger deal out of this than it needs to be. Was it helpful, at least?"

"I..." Helpful was definitely one way to describe it. A certain, very hard, part of my body had found it quite a bit more than just that, but I was trying not to focus on that. I made a mental note to make sure to adjust myself before standing up to ensure Zoey wouldn't notice and be creeped out. "Yeah, I've got a way better understanding than I did before. Thanks for offering to do this."

"Much better. And you're welcome. It... was nice."

Nice? Nice could mean a whole lot of things, and from her extremely neutral tone I wasn't able to tell entirely what she might mean. I could only imagine she was trying to be polite because any other explanation carried far too much baggage with it to consider. At least she hadn't seemed to hate it, or me, and it was a relief to know that my fears of ruining things between us had been unfounded.

"Let's call it here for tonight, though," she continued. "I, um... need a minute."

"Right. Sure." The dismissal cemented that it had indeed been awkward for her and that she needed some space from me to be able to fully process it. I bounced to my feet--knocking several of the plushies onto the floor in the process--and quickly made my way over to the door. Even in the pitch-black room, it was easy to make out, thanks to the light from the hallway filtering through the edges of the frame.

Pulling the door open, I turned back to look at my sister. Her eyes were on me, her cheeks painted in red with her mouth slightly open. There was absolutely no trace of disgust in her expression--if anything, the way she was looking at me caused my heart to beat slightly faster. Both of her hands were hidden in her lap thanks to all of the pillows. She gave me a soft smile, and in that moment she looked so incredibly beautiful that I was forced to turn and leave the room as I felt my face go bright red.

As I walked back to my bedroom, still partially dazed, I was mortified that I couldn't stop thinking about how much nicer the session would have been if Zoey hadn't been wearing a bra.

Session 4



It wasn't working. At all. I dropped my brush back into the jar I stored it in, frustration coursing through me. After everything Zoey had done for me last night, I'd been unable to make any more progress on the painting today. Once I'd returned to my room last night I'd immediately called it a day and gone to bed, but I knew it wasn't the gap of time that was holding me back--I most certainly hadn't forgotten anything from that crazy session. No, the problem was that I now knew exactly what a pair of boobs being supported by a bra felt like, and yet this painting was supposed to be in the nude.

I knew that shouldn't prevent me from being able to finish it, but a part of me wanted it to be as accurate as possible. Which meant I needed to get my hands on a nice pair of tits, free from any constraints. And that felt all but impossible, for all the same reasons as before. There was only one realistic option available to me, and as extremely unlikely as it seemed that she would agree, after our recent interactions, I figured it wouldn't hurt to at least ask. Once Zoey gave me a definitive no--which she certainly would--then I'd be able to move past it and work with what I had. So, before I could think on the matter any further, I grabbed the blindfolds from where they were resting on the top of my dresser and marched out of my room, only stopping when I reached Zoey's closed door.

"Come in," she called out in response to my knock.

Doing just that, I opened the door and stepped inside--taking a deep breath as I closed it behind me. Zoey was sitting at her desk with her computer on, although it looked like she was working on some code and not playing a game. Turning slightly in her chair, she shot me a smile, her eyes dropping to the black cloth in my hands.

"Well this is a surprise," she said, the monitors going dark as she spun around to fully face me. "I didn't think you'd ever be the one coming to me for a session, but I guess after how the last one went things have changed?" Her eyes were twinkling as she finished, and I took the teasing note in her voice as an encouraging sign.

"Uh... yeah," I began. Not the best start, certainly, but now that it was time to actually voice my plan out loud, to my sister, everything became all too real. It certainly didn't help that I couldn't stop staring at her. Zoey was wearing a black crop top that showed off her stomach nicely, and, instead of another skirt, this time she was wearing a pair of denim shorts that were so small they didn't cover any part of her legs.

"You're staring," she said, snapping me back to reality as my eyes shot back upward to her amused look.

"Right. Sorry. So, thing is, I was, uh, trying to paint for the last hour or so, ever since we finished dinner basically, and..." Realizing I was rambling thanks to my nervousness, I got right to the point. "And it's just not working, Z. Don't get me wrong, your help last night was absolutely amazing, but the painting is supposed to be nude and..." As much as I wanted to, I couldn't finish.

One of her eyebrows arched. "Are you asking to see my tits?"

My eyes shot wide open in panic, although her misunderstanding was totally understandable. "No! No, of course not," I hastily explained. "I was just thinking, and I know it's stupid, but maybe we could do what we already did last night again, except this time you could, possibly, um, you know... take off your bra first." I finished in a rush, my eyes now firmly glued to the floor at my feet as I couldn't stand to look at her.

"I see."

I swallowed heavily, waiting for the inevitable denial, only to be met with continued silence. Just as I was about to look back over at her, I heard the sound of Zoey getting to her feet, before a moment later her long legs stepped into view.

"Asking your sister to take off her bra is pretty inappropriate--"

I immediately opened my mouth but was silenced by Zoey's finger pressing against my lips in a shushing motion.

"--but I think your imaginary girlfriend might be willing to help you out. It's for a good cause, after all, she doesn't want you to fail your class."

Imaginary girlfriend? Huh? It took me a second to remember that was the premise we'd gone with last night, and then a moment later it struck me like a bolt of lightning--that she'd said yes. I was still in a daze as Zoey grabbed my hand and tugged me after her in the direction of her bed.

"Wait, are you--"

"Sure? Yup. It's basically the same thing we already did."

Was it, though? I felt like it was leagues apart, but things had escalated so rapidly and given the outcome, I wasn't about to complain. Even so, I was basically a puppet as Zoey pulled me onto her bed before pulling the blindfolds out of my hands.

"Can't forget these. Wouldn't want my brother catching a peek of something he shouldn't see." She even went so far as to tie mine on for me, leaving me in a black void as she finished and I heard her pull away.

What followed was the sound of clothing scraping against skin, in what could only have been Zoey pulling her shirt over her head. Which meant my sister was now standing in front of me wearing nothing more than those skimpy shorts and a bra. Just that mental image was enough to send the blood rushing to my cock. As wrong as it was, a part of me very much wished I was not wearing a blindfold at that moment. The situation only grew even worse as I heard a faint clicking noise, followed by more scraping cloth and then a light sigh of relief from Zoey.
The bra was off. My sister was half naked, her boobs out, in the same room as me. And I couldn't see a damn thing. Obviously, that was the entire point, but never before in my life had I so desperately wanted to be able to see. The thought that I'd soon be touching them, albeit still through her shirt, kept me from doing anything stupid like trying to take the blindfold off. This was for educational purposes, I had to remind myself. To understand in a non-visual way what boobs were like. Not for perving on my sister. Even if that was starting to feel less and less weird as time went on.

Zoey must have tossed her bra on the floor as I heard something hit the ground, before shortly after I heard her pulling her shirt back on. My vision went even darker as I assumed she hit the lights, and then Zoey was settling down in front of me, that now familiar peachy scent announcing her presence as much as the bed's movement. She took a deep breath and then began to talk.

"Okay, you--"

"Yeah, I'm ready for this."

She laughed softly in response. "I bet you are... Okay, we'll do this the same way, where I'll describe your actions and then you can follow along assuming you're comfortable with it."

I nodded, like the idiot I was, before I realized what I'd done. "Right. Sounds good."

Zoey cleared her throat softly and then started. "You're back in your girlfriend's bedroom, in the same position as the previous night. The two of you had such a good time that neither of you could wait to do it again. Except this time, your girlfriend let you know that she accidentally forgot to put a bra on today and that as a result, you'd be able to feel a whole lot more."

I couldn't help but smile at the description, even as it also made my cock harder. I appreciated that she was continuing to drive a narrative that made it seem like we were different people--it made all of this a bit easier.

"Not wanting to waste so much as a second of your time together, you immediately slip your hands around her sides and go directly for your goal."

I hadn't expected her to dive directly into it like this--assuming she might try to get another massage out of me or something--but I also wasn't about to complain. Doing as she'd instructed, I wrapped my arms around her from behind in a pseudo hug before gingerly placing them over her boobs. It was completely and utterly different--entirely unrecognizable from what we'd done before. Without the bra, my fingers sank into her, shocking me with how soft they felt. Even if they were the same general shape, they filled my hands now, allowing me to cup them and feel their weight.

Zoey audibly gasped at the same time, clearly noticing the dramatic difference as well and I froze in place, worried this was already too much. I could feel the rise and fall of her chest as she took several deep breaths, and then, surprisingly, she continued.

"The soft and yet somewhat firm sensation reminds you a bit of a water balloon as the closest comparison you can think of, except there's a natural warmth to it as well, even through her shirt."

She was right. I hadn't noticed it at first, but as I continued to slide my hands around, feeling the shape of her, I was able to make out a faint heat warming my hands. The entire time, my mind was reeling as my fingers continued exploring every inch of her, from bottom to top and side to side. She'd mentioned a water balloon, and while I supposed it was somewhat accurate, the reality was that I'd never felt anything close to this before.

An unfortunate side effect of all of this incredible touching was that I now had a raging hard-on. I couldn't remember being this turned on before, to the point where I was throbbing so much that I desperately wanted nothing more than to jerk myself off. That was clearly out of the question for multiple reasons, not least of which was that I knew my sister would ask where one of my hands had gone if it stopped touching her. Since I wasn't about to start humping her back, that left me with no other option than to do my best to try and ignore the situation.

In an attempt to think of anything else, I focused on the one other giant difference from when she'd been wearing a bra--the giant sign that indicated my sister was being impacted by this just as much as I was. Or, perhaps more accurately, the two signs: her nipples. Each time my hands shifted position around her boobs, it was impossible not to notice the dramatic contrast of their hard, pointed shapes. To make things even more obvious, each time I ended up passing over either one of them, Zoey would make an indescribably cute noise, ranging from a groan to a moan to a whimper. Those sounds in particular were heavily to blame for my current state of affairs--they had no right to be so deliciously tantalizing.

"Your picture is supposed to be nude, isn't it?" Zoey abruptly asked.

The question very much caught me off guard, especially since it was clearly directed at me and not at all a part of the earlier role-play. "Uh, yeah? Why?"

"Then this still isn't good enough," she whispered.

My hands immediately stopped, frozen. "What are you saying?" Even though I knew damn well what she meant.

"Take my shirt off."

"Z... what?"

"Take my shirt off."

"You can't be serious."

"Take. My. Shirt. Off."

My heart was thundering in my ears. I knew what she was getting at, that this would be the only way to truly, one hundred percent understand, but it was such a massive leap. "You... mean my girlfriend's shirt, right?" I asked, trying to do anything to distance myself from what we were doing.

"Sure. Whatever. You slide your hands away from your girlfriend's amazing boobs and down to her sides before tugging her shirt off."

I shouldn't have followed the instructions, but I did. My hands dropped to her sides, my fingers slipping under the hem of her shirt. I paused briefly there, knowing this was a point of no return. Even if we were going to pretend I wasn't doing this to my sister, that this was just a fantasy, the undeniable reality was that I would be touching my sister in an extremely sexual way. But by this point, I was so turned on that it was a struggle to remember why that was supposedly a bad thing.

Slowly, I began to raise my hands, sliding upward against her sides, the shirt raising with them. As I reached the bottom of her breasts I paused briefly, giving Zoey one last chance to call off this insanity. She remained silent. And I continued upward, earning a brief giggle from her as the shirt briefly got stuck on her boobs, something I clearly wasn't used to when removing a shirt. It was also a little awkward to get it past her hair and over her head, but before I knew it, I was tossing her shirt off to the side--leaving her all but naked in front of me.

"Now touch my boobs, for real this time."

My hands were already moving to do exactly that, drawn as if by some kind of magnetic force. I couldn't believe this was happening, that Zoey seemed to be okay with this. For the second time that night, I brought my hands up and around to her now naked boobs. This wasn't as large of a difference as with a bra on compared to a bra off, and yet, somehow, it was. With my skin directly in contact with hers, everything felt so much more real, so much more intimate, and the heat flowing outward from within her was far more palpable. I also couldn't get over just how soft her skin was, how nice it felt under my fingers. But by far the largest difference was her nipples, and how much more texture I could feel without anything in the way.

"Fuck yes, my nipples are so damn sensitive right now. Give them some love."

The entire pretense was just gone at this point, but I was long past caring--thinking only with my dick and not my brain. Bringing the tips of my index fingers to her nipples, I circled them several times, drawing louder and louder moans from her lips. I was amazed at just how hard they were, especially in contrast to how soft the rest of her boobs were. Flicking rapidly back and forth over them pulled a particularly sexual moan out of her.

"Zack, please."

The desperate note in her voice drove me wild and I shifted forward on the bed, completely closing the gap between us as I pulled her flush against my chest. There was no way she couldn't feel the entire length of my hardened cock pressing into her back now, but she didn't say anything about it. Not entirely sure what more she wanted, I adjusted my hands slightly before gently pinching her nipples at the same time.

Zoey's back immediately arched into me, the base of her head rocking into my shoulder. "Yes," she hissed, and the sound was overflowing with so much passion I immediately increased the pressure I was applying by a bit. As an added benefit, the way she was shifting against me was finally giving my throbbing cock some of the attention it had been craving for so long.

Not wanting to risk possibly hurting her by pinching any tighter, I instead opted to slightly twist them. Zoey's reaction was instant as her entire body began to basically vibrate against me.

"So good. It's so fucking good."

On one hand, it was nice, no, amazing to hear how much of an impact I was having on her. On the other, it drove home just how far we'd crossed the line of sibling behavior--especially as I began to grind my dick against her. Both of us were essentially panting at this point, each chasing our own orgasm that was barreling towards us.

"More. I need more," Zoey gasped, and I sucked in my breath as she grabbed one of my hands. It was silly, considering I'd just been playing with her nipple, but for some reason, at that moment, feeling her hand touching mine was overwhelmingly intimate. She was clearly on a mission, however, and not just looking for connection as she began to drag my hand down her body.

As my hand slid past her stomach, it struck me where the only possible destination could be, and just the thought of it was nearly enough to make me explode. There was no way. Surely that was a step too far, she couldn't possibly want me to-- And then our joint hands brushed against those flimsy denim shorts she was wearing as my sister brought me to her core. If I'd thought the heat emanating from her earlier had been something, it paled in comparison to the inferno between her legs. What really caught me off guard though was how wet her shorts were. She was so turned on that she'd soaked through them.

Feeling my sister's pussy juices brushing onto my hand shocked me out of my sex-crazed daze. I lurched backward, nearly falling off the end of the bed in my haste. The abrupt lack of contact with her was immediately disappointing, especially considering just how close I'd been to blowing my load.

"Wait, Zack, what?"

The sheer loss in Zoey's voice instantly filled me with regret, but I had to believe this was the right thing to do. Neither of us was thinking straight, which was understandable, but my request of her had been out of line in the first place and had ended up pushing things too far. "I'm sorry. I can't. We can't." My dick was screaming the exact opposite, demanding release, and I knew that if I stayed there any longer--especially if Zoey tried to convince me as well--then I wouldn't be able to say no. So I did the only thing I could think of: I ran.

Somehow I managed to find the door even with the blindfold still on and I threw it open before staggering out into the hallway. Tearing the blindfold off, I closed her door behind me and raced to my room, extremely thankful not to run into either of our parents and have to explain to them why I was in such a disheveled state. Once in the safety of my own bedroom, I left the lights off and collapsed backward onto my bed, still reeling.

Almost immediately, a wave of guilt crashed over me. Zoey hadn't been upset, hadn't given even the slightest sign that she was uncomfortable. On the contrary, she'd very clearly been extremely into it. And then I'd just abandoned her. I hadn't wanted to ruin our relationship, but now, I might have done exactly that. Bouncing back to my feet, I quickly left my room and retraced my steps down the hallway. I froze right outside Zoey's door--my hand already raised to knock--as I heard two distinct and utterly unmistakable sounds from the other side.

The first was a moan.

The second was my name.

Spinning in place, I fled for the second time that night, moving as quietly as possible so she wouldn't hear me. The last thing I needed was to listen to my twin sister as she lay on her back in bed with her legs spread and her fingers flying over her--I slapped my cheeks with both hands, forcefully ejecting the thought from my mind. Returning to my room, I decided to call it a night. Maybe things would start making sense again in the morning.

Except as soon as my head hit my pillow after I finished changing into a fresh pair of boxers and the oversized T-shirt I always slept in, I couldn't fall asleep. My thoughts kept drifting back to Zoey, and the fact that she'd clearly taken matters into her own hands--literally. Why had she said my name? Was it simply because of what we'd just been doing or... was it something more? Thinking about what she was quite likely still doing at this very moment wasn't helping with the whole falling asleep thing at all, or with the state of my cock which remained as hard as ever.

I rolled from my side onto my back and exhaled loudly. There was no way I was falling asleep like this--not when I was still so worked up and my dick was throbbing. It was all too easy to reach down and slip it through the slit in my boxers. From there, just a gentle rock of my hips caused it to rub against my sheets, giving it at least some of the stimulation it was craving. While it would have been far faster and easier to just jerk myself off until I came, I'd always loved this hands-off approach--dragging out the pleasure until it peaked.

With my eyes closed and my dick slowly sliding up and down, my thoughts drifted to my sister and what she might be doing. I knew it was wrong, but she was clearly thinking of me from what I'd heard, and fuck... it was undeniably hot to think of her. Presumably, she'd slipped her shorts off in order to get better access to herself, and she was already topless which only left her panties. I couldn't decide if it was hotter for her to leave them on or take them off, so I opted to leave them on her.

That meant she was rubbing her pussy through them, and given how wet her shorts had been, her panties must have been absolutely soaked. Her fingers were probably focused on her clit, circling around the swollen little nub as she drove herself closer and closer to her orgasm. My own pace picked up, my hips now rocking faster as I pulled the sheets tighter to try and get even more friction. I was panting, my pending collapse drawing ever closer.

The Zoey in my mind slipped her panties to the side slightly, exposing her pussy fully before she pushed two fingers inside herself. "Zack," she moaned, as she imagined my thick cock pushing into her tight, wet depths instead of simply her fingers. I could only imagine how heavenly that would feel, to pound my dick into her over and over again--obviously far superior to what I was doing now. One of Zoey's hands slipped upward as she grabbed a boob, tweaking its nipple between her fingers and hissing in pleasure.

"Fuck me, brother. Fuck your naughty sister's tight little cunt. Fill me up with your cum."

I exploded, cum soaking into my sheets and splattering all over my shirt and chest. It was easily the most intense, mind-blowing orgasm I'd ever had in my life and it left me gasping for air as I struggled to come back down to earth. By the time I finally did, post-orgasm clarity hit me over the head and made me realize just how much of a mess I'd made. Normally, I would have had tissues ready and waiting, but I'd been too lost in my fantasy to think that far ahead.

By the time I finished showering, throwing my sheets in the wash, and then remaking my bed with a fresh set, I was already starting to doze off. Once my head hit the pillow and I felt sleep creeping up on me, I was forced to acknowledge the truth I'd been hiding from for quite some time now: I wanted to fuck my sister.

Session 5



I dropped onto my bed, feeling like my face had to be on fire. For the entire duration of dinner, I'd been unable to stop sneaking looks over at Zoey--her boobs in particular, and how I now had a much more intimate understanding of them. My brain had tried imagining what they looked like, which, in turn, had sent blood rushing to my crotch to give me a raging hard-on. To make matters even worse, she'd caught me staring over dessert before giving me a wink. I'd immediately excused myself and run up to my room in response.

How was I supposed to be normal around her anymore, now that I was lusting after her? Because I knew very well it was one thing to want to have sex with her, and a completely separate thing to actually do it. For all I knew, Zoey wasn't interested in going that far and was just turned on by the taboo nature of what we'd been doing. Which meant it was up to me to relieve my pent-up needs. Unbuttoning my pants, I came to an immediate halt as the sound of someone knocking on my door interrupted me.

"I'm busy," I called out, hoping it was just my parents and that they'd leave me alone. My dick was aching for release, and I just wanted to wrap my hand around it and jerk one out.

"Oh, I bet you are."

Zoey's voice sent a spike of adrenaline rushing through me. Hastily refastening my pants, I moved over to the door and cracked it open. "What do you want?"

"To talk? Duh. C'mon, lemme in."

Sighing, I stepped out of the way and opened the door a bit wider, enough that she was able to slip into the room. It felt like my heart stopped beating for a moment as I took in what she was wearing. Zoey had clearly changed before coming here because our parents would have had a fit if they'd seen her looking this slutty. She was back to wearing a skirt, although this one was so short it only barely covered her crotch at all. Her upper half was somehow even more scandalous--a sheer, black halter that left her shoulders exposed and ended directly beneath her clearly bra-less tits.

I struggled to pick my jaw up off of the floor as she bounced past me, her ass cheeks flashing out from under the skirt at the motion. My dick felt like it was trying to break out of my pants as I closed and locked the door with shaking hands before turning around to face her--the last thing I wanted was one of our parents walking in while she was dressed like this. "Um..."

"What, you haven't made any progress?" Zoey asked, cutting me off as she stopped in front of the painting.

The disappointment in her voice was obvious, but how the hell was I supposed to tell her that I hadn't worked on it because I couldn't get her out of my damn head.

She turned away from it to face me. "Does this mean all the effort from yesterday wasn't enough to help?"

"No!" I hastily shook my head, my eyes locked onto the hard nubs of her nipples that were easily discernible through the top. "It's just that--"

"See, that's exactly what I was afraid of, so I figured we should just make this as easy as possible." And with that, in one, clean, swift motion, she pulled the top over her head and dropped it on the floor. My mouth went dry as I finally got to see my sister's bare, naked boobs. They were everything I'd imagined and more--firm, pert, and topped off with the most suckable-looking nipples. "There, now you've been able to experience them with every sense. That should let you paint them well, right?"
"Except for taste." The words slipped from my mouth before I could fully process them, clearly inspired by my recent thoughts. My gut tensed, ready for Zoey's rejection that I was a freak.

Except she only gave me a small smirk, taking a step closer. "Is that what you want, bro?" She raised her right hand upward and crossed it over her chest to tweak her left nipple. "To take your mouth and put it on your sister's boob? To run your tongue around her sensitive little nipple before sucking on it?"

I wordlessly nodded, frozen in place.

Zoey continued to play with her nipple, her smile growing even wider. "I see. What a naughty brother you are." She took several more steps closer until we were standing within arm's reach of each other. "You know that brothers and sisters aren't supposed to do things like that, don't you?"

I nodded a second time, my attention fixated entirely on her hand.

Zoey surprised me by immediately closing the gap between us, her body pressing flush against mine as I felt her hardened nipples push through my shirt and into my chest. "But that's also what makes it so fucking hot, isn't it?" she whispered into my ear.

A burning fire ignited inside of me at her words--all the sign I needed that she found the taboo between us to be just as much of a turn-on as I did. Moving my hands to her waist, I half-dragged, half-carried her over to my bed--Zoey shrieking with laughter the entire way. Her laugh instantly changed into a throaty moan as I landed on top of her and fastened my mouth to one of her nipples, doing exactly what I'd wanted to ever since she'd revealed them. I swirled my tongue around it just like she'd described, feeling the difference in texture as I moved on and off her areola. After a brief moment of listening to the soft, sexual noises that were flowing from her lips, I moved on to the next part of her description and gave her nipple a good suck.

"Oh fuck yes," Zoey gasped, her body arching upward into me. "You have no idea how much I've been wanting you to do this."

Increasing the suction, I rapidly flicked the tip of my tongue directly over her nipple, absolutely loving how it seemed to drive her crazy. After about a minute of this, I reluctantly pulled my mouth away and looked up to Zoey's face. Her cheeks were flushed a bright red and the look in her eyes could only be described as lustful. "Was this your plan from the very start, then?"

She blinked a few times and then shook her head. "Oh, not at first, no. I was just curious about your new club, but then after our second session, everything just started feeling so intimate and I realized how comfortable I was around you. I've never been great around guys, but with you, I could just... I dunno, relax and be myself. It certainly helps that you're also exactly my type--speaking of which, isn't it about time for you to lose some clothes too?"

Feeling flustered from both her touching admission and praise, I laughed it off as I shifted around so that I could pull my T-shirt over my head.

Zoey's eyes twinkled as I did so, her tongue running over her lower lip. "You've got some pretty little nips yourself, bro. Might want to get a taste of my own."

As far as I was concerned, she could do anything she wanted to me. It did raise an interesting question, though. "So... what exactly is this? Are we just fooling around or is there... more?"

She giggled, shifting slightly under me. "I think this is whatever we want it to be, as long as we're comfortable with it. We should probably take it slow, at least at first though, so as much as I want your cock to pound my pussy... maybe not tonight."

I groaned at her explicit example, my dick twitching hard enough in my pants that Zoey's eyes widened as she felt it shift against her.

"Seems like someone wants to fuck their sister."

Face burning, I glanced away, unable to meet her eyes. "I mean... can you blame me? Have you seen how fucking hot you are? Not to mention what I heard you doing last night."

"Wait, what? You came back to my room?"

I looked back over, amused to see that it was her turn to be blushing heavily. "Yeah, just to apologize for bolting like that, but then before I could knock I heard you..." I trailed off.

Zoey gave me a wicked grin. "Playing with my wet little pussy? You have no idea how fucking horny I was after all the attention you gave my tits. 'Course, it probably didn't help that I was fingering my clit almost the entire time either." Her eyes gleamed. "What about you? Were you busy back in your room after what you heard?"

Swallowing nervously, I nodded as I thought back to what I'd done--my dick now straining against my pants.

"Fuck that's hot. Did you think of me while doing it?" She was panting lightly, and I realized that she'd started to grind her crotch against my leg, presumably stimulating her clit in the process.

It was hot, and given the situation, there didn't seem to be any reason to be embarrassed about it. So I dove in, excited to see how this would play out. "I did. I imagined you lying on your back, your fingers running over your soaked panties as you touched yourself."

Zoey moaned--the erotic sound music to my ears. "You've got a good imagination, bro. That was exactly what I was doing. Actually... let me up?"

Curious, I shifted my weight off of her, allowing Zoey to slide out from under me. She didn't go far though, coming to a stop as her head reached my pillow. The position left her waist directly at my eye level, and with her spread legs and how non-existent her skirt was, I could see a dark, wet spot right in the center of her crimson panties.

"It was just like this," she said, as she brought two of her fingers between her legs and began rubbing that spot. Zoey's eyes closed as her breathing picked up, and I couldn't tear my eyes away from her fingers and how the wet patch was slowly getting larger. "What were you doing as you imagined this?" she asked, eyes still closed.

As much as I was enjoying the up-close view of the action, I shifted on the bed to mirror her position, leaving our feet close together as I swiftly pulled my shorts off and then spread my legs. "I was grinding my dick against my bedsheets, using the friction to get me off."

"Not your hand?" She sounded surprised.

"No, it makes it easier to draw it out." Not that I cared now, as I placed my hand over my hard shaft and focused on the tip where it was the most sensitive, making small up-and-down movements. "Then, after a bit of that, I imagined you sliding your panties to the side so you could shove your fingers inside yourself and pretend like they were my cock."

Again, Zoey let out a long moan. "God, how do you know me so fucking well?" I could only watch in awe as she did exactly what I'd described, exposing her sopping wet pussy to me as she pulled her panties to the side before plunging her fingers into her depths.

I nearly came then and there, watching my sister fingering herself. My hand stilled, not wanting this to come to an end just yet.

"I imagined your thick cock pounding into me," Zoey gasped, her back arching slightly as her fingers picked up their pace. Her eyes were still shut and I could only stare as she went on. "It would fill me up so much better than my fingers, as I can feel you pulsing and throbbing deep inside me. You're not gentle either, you're fucking pounding my pussy, knowing that I like it when you get a little rough with me. And then once you can't take it anymore, once you're at your limit, I clench myself around you and then you flood my dirty little cunt with your cum."

By this point, her fingers were flying and her body was trembling. Unable to help myself, I leaned forward, reached out, and gently tweaked one of Zoey's nipples. Her eyes shot wide open, meeting my own, and her mouth opened into a wide "o" although, thankfully, she somehow managed to contain what I imagined was a scream as her body visibly shook like an earthquake. Watching her orgasm was a massive turn-on, and I hoped it was only the first of many ahead of us.

It took several minutes for Zoey to get her breathing back under control, but once she did, she gave me a broad smile. "Damn, that was amazing, easily a top-three cum. I didn't expect you to help out, but it made it that much more intense." Reaching down, she promptly shimmied her skirt and panties off, leaving her completely naked. "Right, no more clothes," she said, sounding all business-like. "You're still hiding something that I very much want to see."

I immediately felt nervous about the concept. Showing my dick to someone else, much less my sister, was something I'd never done before, except... There was Zoey's pussy, staring me straight in the face. Realizing it wasn't that big of a deal, I pulled my boxers down before tossing them over to join her discarded panties on the floor. My cock stuck up, hard, and fully erect.

Zoey's eyes widened slightly as she leaned closer. "Wow. It's my first time seeing one in person. Can I... touch it?"

I couldn't nod my head fast enough.

Reaching out, she gently wrapped her hand completely around me before lightly squeezing. It honestly didn't do a whole lot for me on its own, but just the fact that my sister had her hand wrapped around my cock was enough to cause it to throb. "Huh, that's neat. Somehow it's both hard and soft at the exact same time. I've never felt anything like that. And yeah"--she looked into my eyes--"I can already tell this is going to fill me up perfectly."

My dick jumped at her words, pulling another one of those wicked smiles from her that I was coming to dearly love.

"How do I make you feel good? Like stroking it, sure, but any tips for a noobie like me?"

I laughed. "Yeah, that's pretty much it, not too complicated. It is more sensitive right where the shaft meets the head there, so that's what I usually focus on."

"I see." She ran her thumb up to that point and began lightly stroking it, pulling a light grunt out of me. "What about your balls?"

"They're extremely sensitive, and more in a pain than pleasure way," I explained. "I've never really found anything that works well with them so I usually leave them alone."

"Gotcha, I'll give your cock all of my love and attention then."

I would have laughed, except she'd started to regularly stroke my shaft, the motion slow but luxurious. Rather than lying back and soaking it in, I glanced down to where her pussy was peeking out from between her legs. "Z, can I play with you too?"

Her eyes twinkled in response. "I was hoping you'd ask. This will probably work best if we're side by side."

I followed her back up to my pillows where we settled into position slightly propped up. I wrapped one of my arms around her shoulder, holding her tightly against me, and then brought my other across my body to rest on her stomach. For her part, Zoey slid her hand on my side straight down to my cock and began lightly stroking it again before moving her other hand to rest atop mine.

"Okay, so, a pussy is pretty straightforward too," she began, pulling my hand downward. "First, you can cup it like this." She placed my hand directly over her core, causing my heart to beat faster now that this was actually happening. "Since I've already had an orgasm I'm still plenty wet, but if we were starting from scratch you'd want to begin with some external stimulation to start things off--nothing is worse than trying to play with a dry pussy."

She was indeed quite wet, especially so where my fingers were resting.

"There are two main ways you can stimulate me, either externally with my clit, or else internally with the g-spot."

I nodded along, recognizing the terms, although it was starting to get a little difficult to focus since her hand hadn't stopped stroking my cock, even if she was going fairly slowly.

"The clit is probably the easiest and most effective way. If you grind your palm into me like this you can loosely stimulate it to kick things off and turn me on. Since I already am though, you could try sliding a finger or two inside. Just stretching me open will feel nice, and since your fingers are longer than mine you can probably do a better job of playing with my g-spot."

Hesitantly, I slowly pushed my index and middle finger down between her folds and into her wetness, marveling at the feeling as they sunk into her. Zoey gasped as they did, her hand briefly pausing before resuming its earlier motion. I was amazed by the pressure she was squeezing my fingers with. Just the thought of eventually sliding my dick inside her now that I had a better understanding of what it might feel like was nearly enough to push me over the edge.

"Fuck. That feels so different than when I do it myself. So good. You're looking for a slightly rougher texture, right on the other side of my clit. You can try stroking your fingers along the upper wall like you're beckoning someone toward you to see if--Oh god." Her entire body shuddered against me as her head lolled back into the pillows.

I immediately froze, worried I'd someone done something wrong and hurt her. "Z? You okay? Did I--"

She rapidly shook her head. "No. Please, do that again, but with some more force. Use your thumb on my clit at the same time."

Eager to comply, I adjusted slightly to get my arm into a position where I could more easily bury my fingers inside her while shifting my thumb up over the hard nub at the peak of her folds. Just as she'd mentioned, the spot my fingers inside her were lightly touching did feel slightly different than the surrounding area. Taking a deep breath, I repeated the same beckoning motion while also circling the pad of my thumb around her clit.

"This is supposed to be straightforward?" I muttered. I felt like she'd just dropped me into the deep end of the pool and told me to swim for my very first lesson, but it was undeniably hot to watch her reactions to what I was doing.

"Holy fucking hell. Keep doing that, and don't you dare stop." At the same time, her fingers shifted to smaller but rapid strokes directly beneath the head of my cock, where I'd shown her earlier, bringing me right to the edge.

"Z, you're gonna make me cum."

"No shit," she gasped. "Me too."

Somehow, I managed to hold out for a bit longer, until, with a tight squeeze of my fingers and her back arching even more, Zoey let out a loud moan. Hearing and feeling her hit her peak pushed me over my own, and my dick spasmed as shot after shot of cum splattered over my chest and her arm. I stopped moving my fingers inside her, but left them in place, too attached to the feeling to want to pull them out. That had been incredible, both my own orgasm at her hands and watching what I'd managed to accomplish with just three fingers.

Once her breathing evened out, Zoey laughed softly. "Damn, bro. Do you always cum that much? My arm is covered."

Blushing slightly, I shook my head. "Uh, not usually. Only when I'm super turned on does it usually make this much of a mess."

She hummed softly, the noise full of satisfaction. "I see. Well, I'll take that as a compliment then. I'm curious, though."

Before I could ask what about, I watched in shocked silence as my sister brought her other hand over to my chest where she swiped up a patch of my cum with one of her fingers before promptly sticking it in her mouth and sucking on it. The sight was both unexpected and surprisingly hot, enough that my dick twitched in response even despite its recent load.

"Hmmm, not bad, although maybe a bit salty. I definitely taste way better."

I wasn't sure if it was a dare or not, but I was already curious. Zoey gasped slightly as I pulled my fingers out of her so I could get a taste of my own. I'd tasted myself in the past out of curiosity and hadn't been a big fan, but she was right: her pussy tasted way better than my cum did. "You're right," I told her after popping my finger out of my mouth. "I love the way you taste."

Zoey grinned widely back at me. "Wanna eat me out? I bet if I suck your cock enough I can get a second round out of you."

I swallowed. "Like a sixty-nine? Yeah, that sounds super hot." My dick had softened a bit by this point, but just the thought of us giving each other oral was keeping it somewhat hard.

"God I love that we're doing this," she said as I shifted farther down the bed and she flipped around to get in position. "The freedom to just walk down the hall and have you fuck me whenever I want is going to be amazing. Best. Club. Ever."

I knew exactly what she was talking about. The knowledge that I could now walk into my sister's room whenever and just start messing around with her was massively exciting. My thoughts on that rapidly fizzled out as Zoey swung one of her legs over my body and my entire attention was captured by her pussy directly above my face.

"Ready?"

I didn't even bother to respond verbally, instead reaching up with both of my hands to grab her waist to pull her down to my eagerly waiting mouth. Zoey shrieked with laughter at the sudden action, then sucked in her breath as my tongue lapped from her clit to the bottom of her pussy. The position left my nose closer to her anus than I would have preferred, but thankfully all I could smell was the intoxicating fluid already beginning to cover my face. I couldn't believe how wet she was, and I was craving more as my tongue continued running the full length of her lips.

I'd just settled into a nice rhythm when my sister's warm, wet mouth surrounded the head of my cock. Even knowing it was coming, I wasn't prepared at all for how incredible it felt. Her tongue swirled around its head several times and then she began to suck. I moaned into her pussy, my tongue pausing for a moment as I was entirely consumed by my first blowjob ever. My dick was already returning to its earlier hardness, and I knew that if she kept this up then she'd be absolutely right about that second load.

My attention was returned to Zoey's pussy as she not so gently shoved it against my face, reminding me that I was supposed to be going down on her at the same time, even as she picked up her pace and began sucking my length more vigorously. It was incredibly hard to focus on anything other than how good she was making me feel, but I did my best as I flicked my tongue back out and resumed where I'd left off. This time instead of licking her I tried to fuck her with it, but the position wasn't helping and I couldn't get enough depth so I ended up returning my focus to her clit.

As my tongue began to lap away at it again, Zoey's body shook against me, allowing me to feel just how much she was enjoying it. Another idea hit me, and I pulled one hand away from her ass to slip it between us to grab one of her boobs. My fingers went directly for her nipple, gently pinching, twisting, and squeezing it. At the same time, I couldn't help but gently rock my hips into her face as I felt another orgasm brewing.

Unfortunately, it happened to coincide directly with one of her downward motions, and the next thing I knew, my sister was gagging around my cock. A rush of concern immediately flooded me, and I tried to pull back, only to have Zoey moan extremely loudly before surging forward. I nearly lost it instantly as I felt the head of my cock slide into her throat. There was a brief moment of intense pressure and extreme suction before she pulled back, coughing and gasping for air. To my surprise, she dove back in almost right away.

If she was going to go all out like this, then I wasn't going to let her outdo me. Adjusting my mouth, I zeroed in entirely on her clit, no longer making broad strokes, but instead flicking it rapidly. At the same time, I began sucking as well, pulling her clit into my mouth. Zoey went frantic above me, her body quivering and shaking all while her head continued to bob up and down on the entire length of my spit-slick dick. She seemed to have found her perfect rhythm, able to take me deeper and for longer, and I could feel my end rapidly approaching as a result.
Zoey broke first, a rush of her cum flooding my face as an earthquake seemed to overwhelm her body. Combined, the feeling of her orgasm and knowing that I'd done it to her was the final push for me as I exploded into her throat right as she finally managed to completely bottom out my cock. Rope after rope of my cum shot out as easily the most intense orgasm I'd ever experienced rocked my body.

By the time I came down from my high, my sister was back to lightly sucking and licking my cock, with happy noises of utter contentment occasionally slipping from her lips. In response, I flicked my tongue back out across her clit, earning a half-gasp, half-moan before she pulled away slightly.

"Too sensitive still," she said softly, her voice sounding a little gravely as she rolled off of me and then flipped around before crawling back up the bed. She settled in against my side, cuddling into me with one boob resting on my chest and the other pressed into my arm. Her free hand moved to my chest, rubbing it in a gentle motion before her fingers traced their way over to one of my nipples where she began to draw lazy circles around it.

"You okay?" I asked, running my hand up and down her back. "I did not mean to ram my cock down your throat like that."

She giggled softly. "I know. It was fucking hot though, and once it happened I just wanted more, to see if I could take all of you. Prolly not something I'll do too often, but don't worry, I loved it."

"You're not the only one... I just wish I could have done more for you."

Zoey shot me a confused look. "Are you being serious right now? When you started sucking on my clit I saw stars. It was so good you better be prepared for a whole lot of face-fucking in the future."

It was my turn to laugh. "That doesn't sound bad to me at all."

"Good, it better not." She shifted upwards slightly, and before I fully realized what was happening we were kissing. My first thought was 'Oh my god, what, I'm kissing my sister?' but it was almost immediately replaced by 'Oh hell yes, I'm kissing my sister!' Even after everything we'd just done, our first kiss made everything between us feel so much more... real. Her lips were incredibly soft against mine, and I lost myself in the casual intimacy of the moment.

"You still taste a bit like me," she said in amusement after pulling back. "But I imagine you can't taste any of yourself since you shot it all clear down my throat."

Shoving down my embarrassment, I faintly shook my head.

Making a contented noise, she cuddled closer in against me. "Wish I could just spend the night here with you like this, but it's probably a bit too risky."

I knew exactly what she meant. The idea of falling asleep with Zoey cuddled into my side was like a dream come true, but even now we were already pushing things if our parents decided to come looking for one of us. It was a complication for sure, and while the free rent was undeniably nice, for the first time in my life I found myself considering what it would look like to move out.

"Yeah, that would be really nice," I responded, my hand running up her back to idly play with her hair. "Z, I think I'm in love with you."

There was a small pause before she replied. "Well duh, I'm your sister, silly. You have to love me."

I shook my head. "No, that's not what I mean. I love you, love you. Like... bah, I don't know how to say this. Sorry, forget I said anything."

"No! No, I was just kinda... scared, so I teased you. I know what you mean, Zack. I... I love you too."

Even though I'd just said the words myself, hearing them directed towards me felt completely different and I instantly understood what Zoey meant. Pressing a kiss against her forehead, I held her tightly against me as we just lay there.

"I should probably get going," she eventually said, stirring at my side.

I grumbled unintelligibly as she sat up and slipped off the bed, not wanting this to come to an end.

"I know, I know. Don't worry, I'll be back for more tomorrow." She winked at me, and I couldn't help but grin back as she began pulling her clothes back on.

Climbing to my feet, I walked her over to the door. We shared a brief, lingering kiss, and then just like that she was gone, her barely covered ass vanishing into the darkened hallway. Too amped up over everything Zoey and I had just done, and what it meant for our future together, I moved to my easel instead of returning to the bed. Picking up my brush, I began to paint.

Session 6



The following day was nothing short of a complete disaster. By the time I made it back home, I couldn't remember a single thing I'd learned in any of my classes or even much of anything else. I mean, how the hell was I supposed to, when my brain had been filled with nothing but thoughts of the previous night and stuff like how delicious my sister's pussy was. It hadn't helped at all that every time we'd run into each other in the halls she'd given me a little wink, which had been enough to make my dick hard each and every time. By the time we sat down for dinner, side by side, I wanted nothing more than to bend her over the table and take her from behind instead.

"Bit of a change in plan tonight," our mom announced as she set dinner on the table and took her seat.

Despite the lust-filled haze clouding my mind, I could tell something was off from normal, although it took me a few seconds more to realize it was that she and my dad were both dressed up more than usual.

"The Jacobson's are having a rather impromptu get-together tonight, and your father and I decided we'd attend. We'll be leaving in around twenty minutes or so, which means the two of you will be in charge of looking after the house for the evening. You don't have to worry about locking up and setting the alarm, we'll still be back around midnight, so..."

Whatever else she was saying faded off into nothing as it hit me what this meant. Zoey and I were going to have the entire house to ourselves. For hours. I was going to be able to spend the entire evening fucking my sister and we wouldn't have to worry about our parents.

At. All.

I shot Zoey an excited look, but she was still focused on Mom, nodding her head in response to whatever it was she was still going on about. Even once the talking had stopped and we dug in, Zoey wasn't paying me any attention at all, and I started to wonder if I was maybe getting ahead of myself. She had to be thinking the same thing, no? Especially considering she'd said she would be back for more. As the minutes ticked down until their departure, I felt like I was slowly starting to go insane. Except then everything changed as the door slid shut behind them and the sound of their footsteps faded away.

"Your bedroom. Now. Blindfold on. I'll be right behind you."

I didn't hesitate or ask any questions. Just like that, I was on my feet and racing upstairs, my heart pounding in my chest and my cock already throbbing. We were doing this. Finally. Upon reaching my room, I stripped my clothes off in record time before grabbing one of the blindfolds from where it was resting atop my dresser. Moving to my bed, I dropped onto my back before tying it over my eyes--sending everything into blackness.

As I waited, the more and more excited I got. The fact Zoey was taking some time meant to me that she was preparing something, and I couldn't wait to find out what it was--except then it started to feel like she was taking forever. Just as I was starting to wonder if this whole thing had possibly been a prank, I heard the door to my room gently slide open.

"Oh my. All nice and naked already, I see someone has some plans in mind for what's happening tonight." I heard her walk across the room before I felt the bed compress slightly as she sat next to me. "And look at you, all hard and ready, standing at attention." Her hand loosely wrapped around my cock, and I couldn't contain the gasp that escaped me. "Almost makes me want to impale myself on you."

"Yes. Please," I moaned, desperate for exactly that to happen. I wanted nothing more than to feel my sister's wet pussy wrapped snuggly around my dick.

Zoey laughed softly, her hand tightening slightly around me as she began to slowly stroke me off. "That's not how the club works though, silly. You know that. First, I have to describe everything, and aren't you dying to know what I've changed into?"

She had prepared something. It took all of my self-control not to just rip off the blindfold and see what she was talking about. "You're naked?" I guessed, hoping it was true.

"Nope," she replied, popping the 'p' sound before giggling. "But also maybe yes?"

I waved my hand in her direction to try and get an idea of what she was talking about from touch, but it only caused her to bounce off the bed with a laugh. I immediately regretted it as it also meant she was no longer giving me the slow handjob.

"Nuh-uh, no touching, at least not yet. Now, are you going to be a good boy and keep your hands to yourself or am I going to have to leave?"

The threat mostly felt hollow, but I was perfectly willing to go along with whatever she had in mind, especially since it seemed like things were going to be heating up quickly. Pretending to grumble, I moved my hands to my sides. "Fine. I'll behave."

"Mmmm, I thought you might," she said as she returned to her earlier position--including her hand on my cock. "Now, let's get started. It's a sweltering summer day, so hot that you'd never want to go outside and enough that the air conditioning is even struggling."

Given that my bedroom was pretty cool, all things considered, it was a bit tricky to imagine, but I did my best, curious where Zoey was going with this.

"You're resting in your bedroom, wearing nothing at all to deal with the heat when you hear a knock on your door. Since your twin sister is the only one home, you know it has to be her."

Instead of going on with the description, she stopped there, and while previously I would have said the club wasn't about role-play, now I couldn't care less.

"Hey Z, what's up? Come on in!"

Zoey's hand on my cock picked up its pace slightly, not to the point where she was going to make me cum or anything, but enough that it was getting hard to focus on anything else. "Your smoking hot sister enters the room and doesn't bat an eye at your nakedness, even if her attention is entirely focused on your hard cock. 'Hey bro, I thought you might be hot so I brought some ice cream,' she says, holding out a cone in one hand. The vanilla ice cream is already melting and running down her fingers from the heat, but you hardly notice that as you take in what she's wearing."

"What? What are you wearing?" I was desperate at this point, knowing that she was about to describe whatever it was that she'd changed into."

"A bodystocking."

I blinked under the blindfold. A what? I'd never heard of that before. "What?"

Zoey giggled again. "You know what stockings are, right? Well, this is basically the same, except it doesn't stop at the top of my legs. It goes all the way up to my neck, leaving my arms bare. Oh, and one other little detail, it's fishnet, meaning it covers basically nothing at all."

My mouth was all but watering at the description. Zoey had a pair of fishnet stockings that I'd snuck countless peeks at over just the last year alone, loving how they emphasized her legs and yet hid nothing from view. The concept of her wearing something like that but on her entire body... "Wait, does that mean I can see--"

"Yup. It's hot, after all, and I'm trying to cool down so my tits are in plain sight with my hard little nipples poking out between the fabric. And my wet little pussy is right there, with a trail of liquid running down my thigh from where I was fingering myself as I put this on and imagined your reaction to seeing it."

Even though I couldn't see it. And I desperately wanted to. Swallowing, I did my best to continue my side of the role-play, hoping it would lead to the removal of this damn blindfold sooner than later. "Oh. Thanks, Z. That's super nice of you. You're looking very hot too, why don't we share it?" Had she actually brought ice cream up with her?

"Your horny sister walks over to the bed before climbing up onto it."

To my disappointment, Zoey's hand pulled away from my cock as she shifted around on the bed. I couldn't quite tell what she was doing, but it seemed like she was standing over me.

"Oh, no, this is all for you. Now, enjoy your treat." The bed creaked lightly and then I felt something settling around both sides of my head right before something else very wet and not at all cold like ice cream was pressed into my mouth. "Eat your ice cream, Zack," Zoey commanded and my tongue lapped outward instinctively, even as my brain pieced together that I was eating out my sister's pussy.

I dove in with a gusto, my tongue tracing over her lips before I moved up to flick it over her clit. She hadn't been joking about being turned on or fingering herself--her juices were already soaking my face as I ate her out.

"Oh fuck yes. Eat your slutty sister's wet cunt like a good brother. Shit, you're so damn good at this!"

Even though it was at times difficult to breathe with her pussy smothering me, I was enjoying this about as much as the sounds pouring from her mouth indicated that she was. Listening to her talk dirty was also having a strong impact on me, especially considering they were things I never expected to hear coming from my sister.

Just as Zoey felt like she was on the verge of an orgasm--her legs clenching my head between them tightly--she surprised me by slightly pulling away, breaking my tongue's contact with her. "I know I've been pushing the club angle, but I really want to take your blindfold off. I imagine you don't mind?" She laughed as I frantically shook my head no and then a moment later I felt her reach behind my head to undo the knot I'd tied before pulling the cloth away.

As I blinked rapidly to restore my vision, I sucked in my breath. Directly in front of my eyes was my sister's soaked, spit-covered pussy. Her lips were slightly red and swollen from all the attention I'd been giving them and just above, faintly peeking out from its little hood I could see her clit. Dragging my eyes upward, I very quickly realized that Zoey had left out a key detail of her outfit. It was crotchless. Which, in retrospect, explained why I'd had full access to her pussy without anything in the way.

"Like what you see?"

I could only nod mutely in response.

Zoey giggled. "Thought you might." One of her hands reached up to squeeze a boob. "From how much you seemed to like my stockings, I thought this might drive you crazy so I went and picked it up after class today. And look, it can do this too." She grabbed each side of the top with one hand and pulled the flimsy covering together, leaving it nestled between her breasts and fully exposing them to my hungry eyes. "Not like it shows all that much more, but this way you have full access," she finished with a sultry wink.

"How are you so fucking hot?" I breathed, completely in awe.

Grinning widely, she slid further down my body before leaning in and giving me a deep kiss. "You say the nicest things," she whispered into my lips, before pulling away. "And as tempting as it is to let you eat me out to an orgasm, I really need something nice and thick inside me right now. Have any ideas?"

I swallowed and nodded once again, thrusting my hips upward. It was finally time.

"Oh right, you've got that nice, hard cock, don't you? That would be perfect, wouldn't it?"

Zoey continued to slide herself down my body until she was sitting on my thighs with my cock jutting up between her legs. Just seeing it so close to my sister's ready and waiting pussy was one of the most erotic things I'd ever witnessed. Shifting forward, her pussy lips finally came into contact with my dick as she began to grind them against it, not taking me inside her but instead sliding my length between her folds.

"Mmm, but maybe this is enough. I'm pretty sure I can cum just from rubbing my clit on you."

She was obviously teasing me, especially because each time she reached the tip of my cock she'd shift forward ever so slightly to act as if she was about to ride me for real. It was hard to complain given how good it felt for me as well--it was taking nearly everything I had not to cum myself--but the knowledge that it would be so much better inside her pushed me to try and slip in the next time she was in the right position. Except, somehow, she anticipated me, her body moving up and away at the exact same time I thrust my hips upward.

"I can read you like a book," she said, giving me the very definition of a shit-eating grin.

"Z, come on," I begged, unable to take it any longer. "Just let me fuck you."

Her eyes sparkled. "Well... when you put it that way!"

She sat back down on top of me, but this time the fun and games were over as my cock slid between her lips and pushed into the depths of her pussy for the first time. The sensation was unbelievable. Feeling her tight warmth completely surrounding me was like nothing I'd ever experienced before when masturbating. And the knowledge that I was buried balls deep inside my twin sent everything to the next level.

Zoey moaned--a primal sound that sent shivers down my spine as she arched her back, pushing me even farther into her, and then, somehow, she tightened her pussy around me--squeezing my dick. It was my breaking point, especially after how close all the grinding had already gotten me, as I lost the last bit of self-control and came inside her. Shot after shot of my cum fired into my sister, and from her wide mouth and eyes I could tell she felt each and every one.

A surge of shame immediately flooded me as my orgasm came to a close. We'd only just started having sex, for our first time ever, and I'd already cum. I knew that while Zoey was probably fairly close to cumming herself, she certainly hadn't yet and that was all my fault.

And I had to fix it.

Raising my hands to her waist, I rolled us over to the side, shifting us around so Zoey was now the one on her back. She shrieked at the sudden repositioning, but I was already pounding away between her legs, thrusting my cock into her pussy over and over again. Remembering what she'd said from last night about being a little rough, I didn't hold back, watching in awe as I made her boobs shake from how hard I was fucking her.

"Yes, yes, yes, yes, yes," she gasped, her head falling back as her hands tangled the sheets on either side into a tight grip. "Fucking fill my cunt with your cum."

With all the stimulation, my dick was managing to stay hard, and through the post-orgasm numbness, I could feel the faintest tingles of a second one on the horizon. I knew from past experience jerking myself off that it was still going to take a while for that to happen, but that was perfectly fine--I was entirely focused on Zoey at this point, not myself. While I would have loved to kiss her or suck on her delicious nipples while I fucked her, there was just no way for me to do that while I was pounding her like this, and given how much she seemed to be enjoying it I wasn't about to stop. We could always have a more romantic fuck later on anyways. Taking a brief pause, I shifted her slightly again, holding her butt off the bed a little into a position where I was able to drive just a bit farther into her.

"Fuck, I'm cumming," she screamed, right after I fully hilted myself in the new position.

I felt it as her pussy spasmed around me, clenching my dick over and over again as I continued to drill into her, a wail of pure joy flowing from Zoey's lips as words seemed to completely elude her. By this point, my cock was coming alive again, and even though I was very much feeling the strain from having fucked her this hard for so long, I pushed onward, desperate to give her a memory she'd never be able to forget.
Her entire body was shaking and vibrating at this point as her back arched off the bed. "Too much, it's too good," she half-moaned, half-mumbled. "But don't you fucking dare stop yet." She lifted her head back up and met my eyes with a smoldering look. "Make me yours. Mold my cunt into the shape of your cock."

Tearing my eyes away from hers, I watched the mesmerizing sight of my dick sliding in and out of her. It was a slimy mess from both of our combined fluids, but just seeing my cum leaking out of her pussy proved to be the second trigger that pushed me over the edge as I exploded for the second time inside her. Almost immediately Zoey came again as well, her body quivering before going completely limp.

I collapsed on top of her, gasping for breath as we both came down from our shared high. Almost as soon as her breathing had evened out, Zoey's hand made its way to the back of my head before she pulled me in for a deep kiss. "I love you," she said as we broke apart.

"'Cause I'm a good fuck?" I asked, one eyebrow raised.

"Well... yes. But also because you're you. The best brother a girl could ask for."

I laughed and shifted off her to one side. "Even if I'm an old man who goes to bed early?"

"We can fix that," Zoey said with a smile. "You'll be too busy fucking me to want to go to sleep."

"Mmm, I like the sound of that." I kissed the curve of her exposed neck, drawing a pleased noise from her. "Stay here tonight? I wanna sleep with you."

"Yeah, sure. Mom and Dad will be getting home late enough that they're just going to crash right away. I imagine we could both use a cleaning before falling asleep though," she finished with a giggle. "And probably some new sheets too."

We showered together in my bathroom, and while it was sorely tempting to go for a third round with my sister's soapy, sexy body sliding against mine, we were both too drained to do anything more than cop a few feels. After that, with a quick change of the bed, it wasn't long before Zoey was nestled into my side with her head resting on my chest.

"So much for not going to bed early," I teased her, noting that it was only ten o'clock by this point.

"Shush. I'd come up with a witty retort but you must have fucked them all out of me."

I could only laugh softly in response as I felt myself slipping closer and closer to the land of dreams. Everything we'd just done together almost felt like a dream, but it hadn't been, and that's what made it so special. Zoey and I were closer than ever before, and our future together held nothing but promise.

The next morning I unsurprisingly woke before Zoey. Opening my eyes to find her lying next to me made me surprisingly emotional and it was only enhanced by the gentle rays of sunlight filtering through the window curtains and dancing patterns across her hair. She was so incredible.

Careful, so as not to wake her, I slipped out of bed and padded over to my easel where the painting was waiting. It was nearly finished, only waiting for the final details of the face to be fully complete. Grabbing my brush, I set to work carefully completing my masterpiece. I knew that I was no longer going to be able to use it for my school project--not without raising far too many questions I didn't want to answer--but that was fine. I'd come up with something else, and this was far more important than any of that anyway.

I smiled as I put the finishing touches on the painting, Zoey's excited face beaming back at me with a twinkle in one eye. It had always been that simple. As far as I was concerned, she was the definition of beauty.
