	Chapter 1

Craig looked nervously at his sister. She met his gaze, bit her lip, and a silent conversation ensued.

“Are you sure you want to do this?” he asked wordlessly, and in response Petra simply nodded her head. The pair stepped forward in unison, entering the house of Mason DeGraves, beginning a visit that they knew would change their lives forever.

Ever since he arrived in the neighborhood Lord DeGraves had been an enigma. No one knew how he had gotten his money, where he’d come from, or why he’d chosen to live there. No one even knew quite how old he was—all that was known was that he had more money than any one person should reasonably have—and that he was willing to part with it, for a cost.

“Dares” didn’t quite do it justice—they were more like experiments. Perverted experiments. Completely legal, of course—Lord DeGraves could afford a literal army of lawyers, and though there had been a handful of lawsuits, they’d been thrown out. Sick and twisted though his actions were, it was clear that he was operating entirely within the bounds of the law.

The people who went through with it always came out changed. But they also came out rich—he kept his promises, and if you followed whatever rules he set, DeGraves would make sure you were compensated.

Craig and Petra had read his latest advertisement, and been unable to resist: he was looking for a brother-sister pair. They didn’t desperately need the money, but when they saw the price of his “bounty”, it was too alluring to resist. Two million dollars— _each_ —for two month’s work? No matter what he had them do, it would be worth it…and since he had to abide by the laws, they knew that it couldn’t be anything _too_ bad.

As they stood outside the wealthy man’s huge wooden doors, Petra’s hand reached out and grabbed Craig’s. She was two years older, but the two had never really fought, the way siblings do—this strong bond had made them confident that they could get through whatever Lord DeGraves ordered.

To their surprise, DeGraves met opened the door himself—a hungry look came over his eyes when he saw the pair, standing there and holding hands. Craig was dressed casually in jeans and a T-shirt, but his attention was focussed on Petra—she was wearing one of her favorite skirts. It ended just above the knee, but the old man’s leer made her feel utterly exposed.

“Come this way,” he said gleefully, and the siblings briefly glanced at each other before dutifully following.

Inside the old man’s office, he gestured for them to sit.

“Is there another chair?” Petra asked, looking at the small seat in front of Lord DeGrave’s huge desk.

“Sit,” he replied. “Both of you.”

There was a moment of hesitation, but not wanting to throw away a chance in a lifetime because of a little awkwardness, Petra took the initiative, pushing Craig down and sitting on his lap. She was determined not to let the old man make her feel uncomfortable, though a blush quickly spread across Craig’s cheeks.

“Now,” Mason began, “the pair of you are blood relatives, yes? You share the same birth parents?”

“That’s right,” Petra replied, holding eye contact as confidently as she could.

“Excellent, excellent…I’ll remind you that if that’s a lie, the contract is null and void, and at the end of the two months, you’ll get nothing. Do you understand? I’m _only_ looking for blood relatives.”

“Of course,” Craig muttered, unable to bring himself to look directly at the old man.

Lord DeGraves pressed a button on his desk, and a few minutes later a young lady dressed in a sexy French maid’s outfit brought the siblings a cup of tea each. As she bent down to refill her master’s tea-cup, her skirt rode up, and it became obvious that she wasn’t wearing anything under it.

Petra suddenly began to regret her decision to sit on her brother’s lap, and dug an elbow into his side.

“Ow!” he exclaimed, and his face went even redder as he realized the purpose of his sister’s attack. “Oh, shit…sorry. Just…give me a few minutes. I, uh…sorry.”

The chambermaid blocked the old man’s view of the two, but as she tottered out of the room again, he had a huge grin upon his face, as if he knew exactly what had just transpired.

“That’s Bethany,” he said, gesturing to the door. “I offered her five hundred thousand to be my maid for a month. She liked it so much she’s stayed on full time…”

Petra and Craig shot each other a glance. The busty girl who had just left couldn’t have been much older than Petra—why would she throw away her life to serve tea to a lecherous old man? For a second, both of them considered leaving, and as if he could detect their shared impulse, Lord DeGraves got straight to the point.

“Four million dollars. For that, you would think that much more than a month of housework was needed, wouldn’t you?”

Petra nodded, while Craig focussed on trying to deflate his erection. He sipped his tea, trying to avoid avoiding picturing Bethany naked, wondering if her duties involved more than just serving her master’s guests. Wondering if she had to service him as well…

That did it. The mental image of DeGraves naked was enough to completely deflate his boner, and he tuned back into the conversation.

“You’ll receive it in cash at the end of the two months, provided you follow my every instruction. I’ll provide you with security to deposit it into a bank, if that’s how you choose to deal with it—I wouldn’t want you to lose it between here and safety now, would I?”

“Of course not,” Petra said, politely sipping at the tea that she’d been provided. It was much better than she expected—milky, sweet, and not too strong.

“My terms are simple—for the next two months, starting the second you leave this office, neither of you are allowed to masturbate. You aren’t allowed to use sex toys on yourself, you aren’t allowed to deliberately stimulate yourself with your hands or other body parts, and you may not rub against inanimate objects to get yourself off. What’s more, neither of you may pleasure—or be pleasured—by any sexual partners. No girlfriends, boyfriends, fuck buddies…no one.”

The pair sitting in front of him nodded. Two months of abstinence would be hard, but for four million dollars, they’d been prepared for something much worse.

“For the next two months,” Lord DeGraves continued, a crude smile appearing on his face, “if you want to get off, you have one course of action—each other.”

If Petra hadn’t just swallowed the last of her tea, she would have spat it out in shock.

“Lord DeGraves!” she exclaimed, “You can’t be serious! You expect my brother and I to…to pleasure each other?”

“Not at all,” he replied with a chuckle. “You have that option, of course, but you also have the choice to be abstinent. It’s only two months, after all—I know that you’re young, but I’m sure that you can tough it out for that long.”

“Isn’t that illegal?” Craig asked, and Petra noticed that his cup was also empty.

“Abstinence? I certainly hope not,” the old man replied with a grin.

“Asking a brother and sister to pleasure each other…” Craig replied. Somehow the tea had given him courage, and he was able to make eye-contact with the rich old man.

“First of all, I’m not asking that. You two are the ones with the dirty minds—I’m just saying that if you’re completely unable to stop yourselves from getting off, that’s your only option. Secondly, it’s only intercourse that’s illegal, and in no way am I suggesting that. Brothers and sisters can jerk each other off until the cows come home—there’s no law against that.”

Lord DeGraves sat back in his chair, his crooked teeth showing as he grinned wickedly. He looked like he took a real pleasure in shocking them with his crude words, and the siblings found it a struggle not to flinch in response to his unwavering gaze.

“How,” Petra said softly—the tea seemed to have had the opposite effect on her, making her feel softer, slower, more submissive. “How can you expect to monitor this?”

Ever since he’d laid eyes on them, Mason DeGraves had been all smiles and leers, but at Petra’s question, his face turned dark.

“You don’t want to lie to me, young lady. Trust me on that.”

* * *

The bus ride home was awkward, to say the least. The pair had agreed to DeGrave’s terms—how could they not? Four million dollars in exchange for two months of abstinence? It was impossible to turn down. But it wasn’t until they sat on the bus that they realized what they’d signed up for.

If they found themselves horny beyond all reason, they had two options—they could forfeit the money, or they could…

“We just won’t,” Craig had stated assertively, and Petra had found herself nodding more than she’d originally intended.

“Of course we won’t,” she said, and that seemed to be the end of it.

* * *

### Craig:

The first week was easy. Seven days without masturbation is hardly a struggle—I’d gone longer than that when I’d had to. Family vacations and the like. So for the first seven days, my sister and I had no problem abstaining.

Sure, I woke up every morning with a boner, but a quick cold shower was enough to solve that problem, and then all I had to do was spend the rest of the day not thinking about sex.

The second week…that’s when things started to go downhill.

See after about a week, hormones start to take over. It’s easy enough to say “don’t think about sex”, but after a week without release, _everything_ starts to remind you of sex. I swear the girls in my class all simultaneously decided to wear the hottest clothes that they owned, and my favorite teacher—Mrs Bloomsdale—kept throwing me saucy glances.

I know, I know, it was all in my head…but it just wouldn’t stop.

And then, completely unbidden, the image of Bethany popped into my mind. The maid at Lord DeGrave’s manor—I had never seen anyone so sexy, so curvy…I couldn’t stop thinking about her. Her ass had been so perfect, and suddenly my mind wouldn’t stop obsessing about her pussy—was it shaved? I imagined she had big puffy lips…she was so deliciously curvy…

I tried not to think about it. God knows I tried. But late at night, I couldn’t stop thinking about her, what she’d look like out of the maid’s costume, kneeling in front of me, promising to do whatever I liked…

Maybe it wasn’t fair to Petra. But I knew that if I didn’t do something soon, I wouldn’t be able to stop myself. I managed to last three days—three days with Bethany’s body bouncing around my brain, before I caved.

It was a Wednesday night, around 1am. I’d gone to bed early in the hope that I’d drift off and get to sleep, but I just couldn’t stop thinking about her. It was like someone had put a spell on me—no matter what I did, no matter how I tried to distract myself, the image of Bethany’s maid outfit wouldn’t leave me. My hand kept drifting to my prick, and I knew that if I didn’t do something soon, I’d be cheating us out of four million dollars without even meaning to.

And so, as much as I hated to do it, I crossed the hall and knocked on my sister’s door.

“Craig!” she said in sleepy surprise, as she opened the door—she’d obviously been awoken by my knock. I shushed her—if Mom and Dad woke up, there’d be no way of explaining what we were doing, meeting at 1am. We hadn’t told our parents about the wager, or experiment, or whatever you want to call it.

And if they walked in on us doing what I was pretty sure we were going to do, I don’t think there’d be any way we could explain it to them.

It only took Petra a few seconds to realize why I was standing at her door.

“Oh,” she said flatly, then shook her head to try to get the cobwebs out. “Seriously?”

“I’m sorry,” I replied, and I meant it. I wouldn’t normally have done this…but with a seven-figure payout on the line, I didn’t have a choice.

“It’s only been a week…” Petra said with a roll of her eyes. “You seriously couldn’t hold off for a week?”

“Ten days,” I replied, looking my sister straight in the eyes. “And you know I wouldn’t be here if I didn’t have to be.”

Petra seemed taken aback by my directness—ever since we’d visited Lord DeGraves, I’d felt more assertive than I normally did. Maybe it was the prospect of being wealthy, I dunno. But she sighed, looked down at my tented pants, and gestured me into the room. She sat on the edge of her bed, and I sat down next to her.

“I guess we’d better get this over with,” she said, reaching into her bedside drawer and pulling out a pair of gloves.

“Gloves?”

“I figured you probably wouldn’t be able to last the whole two months, so I made some preparations.”

Her lack of confidence in my staying power annoyed me, until I realized that yeah, she was right. She put on the gloves, covered her right hand with a generous amount of lube, and turned to face me.

“Should I…”

“Come on,” Petra said. I had to admire the matter-of-fact way that she was approaching this. “Let me know how you want it.”

I’d never been asked that before. Truth be told, I’d never received a hand-job at all—my ex-girlfriend and I had fooled around, but we’d never gone beneath the pants. My first ever sexual contact was going to be with my sister…how sad was that?

I pulled my pajama pants down, leaned back onto my elbows, and tried to communicate what worked best for me. In what I assume was an attempt to make it as un-weird as possible, she took on a professional persona, and obeyed my instructions exactly.

With a bit of effort, I managed to ignore the surge of power I felt, having my sister handling my member and doing exactly what I said, and thought about Bethany. Her big, jiggling jugs…her sexy maid costume…even the fact that she was voluntarily still serving the old man was sort of sexy.

The thought of Mason DeGraves having intercourse with her crossed my mind, to my horror—I couldn’t think of a less sexy man if I tried. I’d been so close, but at the idea of his old, wrinkled flesh pressing up against her young and supple body…my boner immediately began to soften, and my sister gave a cry of anguish.

“Craig!” she said, and I couldn’t help it—I snapped.

“For fuck’s sake, Petra, do you think this is easy? Just shut your mouth and keep jerking.”

I immediately regretted my words, but instead of the torrent of abuse I was expecting in response, Petra glared at me for a second…and did exactly what I asked.

“Fine,” she muttered, and began toying with my testicles in an attempt to get me hard again.

“Do you have any porn?” I asked—perhaps I shouldn’t have pushed my luck, but I was horny and I wanted to get this over with.

To my surprise, Petra nodded, and gestured to her MacBook. I opened it, and she directed me to a hidden folder, full of—and no, I’m not making this up—videos of girls giving head to strangers.

“Petra!”

“Don’t say a word,” she hissed, and continued to glare at me, while stroking my rapidly-hardening cock up and down.

Honestly, porn videos have never been a huge turn-on for me, but there was something sexy about my sister’s secret fetish—it wasn’t long at all before I was hard again, and my sister’s skillful hands ( _she_ had definitely done this before) soon brought me to the edge of climax.

“I’m going to…” I said through gritted teeth, my eyes upon the girl on the screen as she pulled the enormous cock out of her mouth and aimed it at her face.

“Oh, shit…” Petra said, and it suddenly became clear to both of us that despite her preparedness, she hadn’t thought about what to do when I actually came. In her panic, she froze up as—in time with the man on the screen—I released my load all over my sister’s shocked-looking face.

Eleven days of abstinence (I hadn’t jerked off the day before we went in, either) had resulted in quite a build-up: I’ve never measured or anything like that, but I’d guess that my load is the normal, average amount.

This? This looked like a scene from a bukakke film. All I could do was watch as I unloaded string after string of cum onto my poor sister’s face. It felt like it went on forever—finally, after five or six spurts, my cock relaxed and began to wilt almost immediately.

There was a long pause, before Petra shrieked. I silently gestured to her what a bad idea it was, gesturing at the door, trying to express how bad it would look if Mom and Dad came in the door at that moment—but it must have been our lucky night—our parents managed to sleep through Petra’s wails of anguish.

I should have done more, I know, but the sleepiness that had evaded me until then suddenly hit, and so I got up, threw my sister the towel hanging on the back of her door, and left the room. I knew I’d never hear the end of it, I knew that—but for now, all I wanted to do was rest.

My exit was inspired by a few things—the fact that I really didn’t want to endure my sister’s angry tirade that night, for one…but I was also avoiding something even more alarming. I had just cum, so sex should have been the last thing on my mind…but there was something about my sister’s angry, cum-covered face that I found erotic, and _that_ was a thought that I didn’t want to explore any further.


	Chapter 2

### Petra:

I couldn’t believe it. Four days later he was back again.

I let him in, of course—with four million dollars on the line, how could I not? And besides, he was only human…I knew how hard it was for guys to go without getting off. I mean…well, I’d been struggling a little myself.

Not that I’d ever admit it, of course. No, as far as my brother was concerned, I was flying through this without effort. But with every day it was getting more and more difficult, and the temptation to just rub my legs together in just the right way, to slip a finger or two under the waistline of panties…

But I had to stay strong. The amount of money on the line was truly ridiculous, and all I had to do was withhold from pleasuring myself. For two million dollars, I’d be willing to do anything.

Including, it seemed, jerking off my brother.

Like I said, I understood his urges. I’d managed to hold back so far, but realistically…I didn’t know how much longer I could continue to ignore my needs.

I let him in, sat him on my bed, and pulled out another pair of gloves. After Mason DeGraves had made us the offer, I’d tried to cover every possibility—I hadn’t told Craig, but I was prepared for him to urgently need my attention in my room, or at school…I’d even carefully hidden a kit in the family car, in case we went away somewhere and hormones struck.

I figured if I told him, he’d take it as an invitation, and I really didn’t want this to be anything more than a last resort. And after last time, I’d added something else to the kit as well.

“A condom?” Craig asked, a sad look upon his face.

“Seriously?” I replied, one eyebrow raised, and he saw what I was getting at and shut up immediately. He pulled his pants down, his cock came into view, and I rolled the condom on, lubed it up, and began pumping.

His instructions had been pretty basic, but I remembered exactly what he liked. I knew the condom would reduce sensitivity, but compared to…well, it was worth a bit of extra effort.

As I stroked him, I tried to think of something else. I really didn’t want to focus on the cock in my hand, or the fact that it was the first member I’d touched since my ex and I broke up…

Here’s the thing. I don’t masturbate an excessive amount—maybe once or twice a week? I don’t really keep count. I don’t get particularly horny when I’m single…but when I’m with a guy, it’s a whole other story.

Again, I’d never tell Craig this, but I find cocks to be super hot. It’s something about the look of them, the touch of them, the taste of them…I just like cock. I’m straight as they come—normally, my proclivities wouldn’t be a bad thing, but the longer my hand was wrapped around Craig’s, the harder it was to ignore that what I was doing was pretty much one of my favorite things.

And the more I thought about the cock in my hand, the more turned on I got. God damn it, I never thought that “liking cock” would be something that could come back to bite me in the ass…but of course, I never expected to be forced into touching my brother’s.

I’d been shocked, last time, when he’d…y’know…but again, the act is sort of a turn-on for me. I love cock-worship videos, and my favorites are always the ones where the girl got a load blown all over her face. My last boyfriend had enjoyed it just as much as I had, and in the last few months, I’d even considered paying him a visit, just for old time’s sake.

If I was able to masturbate, I’m sure I’d have easily been able to get the whole thing out of my system. But 14 days had really started to take their hold on me—I’d hoped it would just go away after a while, but it had kept building and building and building, and now just the simple fact that there was a cock in my hand was starting to turn me on in itself.

I felt like a pervert, some kind of sick fuck who was actually _enjoying_ getting her brother off. At the same time, a small part of me couldn’t help but reason “Hey, if you have to do it anyway, you might as well get some pleasure out of it…”

The thoughts wouldn’t stop racing through my mind—I was conflicted and aroused and angry at myself, and it wasn’t until I realized that Craig had been talking to me for a while that I snapped out of it.

“Petra?” he was saying, and I looked at him in a weird, guilty shock. He’d been so much more assertive lately…just to add to the humiliation I was feeling, I even managed to find _that_ to be a turn-on.

“Yeah?” I said, acting as aloof and annoyed as possible.

“I said slow down. Pay attention, would you?”

Two weeks ago, I would have snapped at him, told him I didn’t have to keep going at all. But something indefinable had changed in our dynamic, and all I did was nod, apologize, and turn my efforts back into getting him off.

“The sooner I get him off, the sooner I can get him out of here” I told myself, but a part of me didn’t want him gone. Some horrible part of me was enjoying this.

What the hell was wrong with me?

_Pay attention,_ I told myself, and I began using both my hands.

I used the best techniques I knew—one hand played with his balls while the other stroked him. My lube-coated hands were being used to great effect…and the more attention I paid to his hardness, the more I realized I was getting turned on by it.

_This would be so much easier if I just used my mouth,_ I told myself, before mentally swatting the stray thought away and trying to pretend that the cock in front of me didn’t belong to my brother.

_But it does,_ a voice said, and I silenced _that_ one as quickly as possible. That was certainly something I wanted to think about as little as possible.

Before long, my brother was gently thrusting forward, and soon after that I saw the condom filling up with his spunk. It didn’t look like nearly as much as last week, when it had managed to coat the entirety of my face.

_Gross,_ I thought, but without the conviction that I felt the thought deserved.

“Thanks,” Craig said dismissively, tying the condom off and pulled his pants back up.

“No worries,” I replied, pulling off the gloves and throwing them out. There was an awkward pause, and he began to leave.

He was almost completely gone before I said anything.

“Wait!” I cried out, and Craig poked his head back into the room.

“What’s up?”

“I…”

Another long pause ensued, and I could tell he was getting tired.

“I…was wondering if…”

Again, there was a silence, but as Craig’s eyes widened, I knew he had realized what I was getting at.

“For real?” he said, and I just nodded, my cheeks beet-red. “But I thought girls…”

“Yeah,” I replied. “Normally we don’t. It’s just that…”

Again, I didn’t have to finish the sentence. I think Craig realized how much it had cost me, silently confessing that jerking him off had turned me on, and so he didn’t ask any follow-up questions, or push the point any further. But I saw a slight swagger to his step as he re-entered the room, and once more sat next to me on the bed.

We just sat there, two blushing siblings, until I threw him a pair of gloves.

“Oh, I don’t mind.”

“I do,” I insisted. “Put them on.”

After he had, we continued to avoid eye-contact, until I glanced at the clock and saw that it was almost 2am. If I didn’t start things now, we could be here all night, and I had a busy day the next morning. With an orgasm to prevent sex taking over my brain the whole time, it could be a productive day—provided I got to sleep sooner rather than later.

“Okay,” I said, trying to act as professionally as possible. It had worked to keep this as un-weird as possible so far, it could work now. “I’m going to take my pants off—have you ever done anything like this before?”

“No,” he said, but without any awkwardness. Good. He’d obviously taken my lead. I sort of wished he wouldn’t stare at me so intently, but it was probably better than the alternative.

“That’s fine,” I said matter-of-factly. “I’ll talk you through it. Now turn around while I undress.”

A few seconds later, I sat in front of my younger brother naked from the waist down.

“Okay,” I said. “I’m already quite wet, but a bit of lube wouldn’t go amiss. Yes, that’s enough. Good. Now, take two fingers, and slowly start drawing little circles around my clit. No, lower than that. Lower. Waay lower…here, look where I’m pointing. Yes, that’s—oh, wow. Yes, that’s the spot. Good. Now, normally I’d just do that for a while, but…oh f—…yes, keep doing that. Mmm, yes. Yes.

“Okay, now, uh, take your other hand, and just use one finger for now. No, don’t just—don’t just stick it in. Jesus, Craig. Play with my lips. Run a finger up and down, and they’ll open up like a flower. Once they have, you can…oh yes, that’s it. Yes…slower. Oh, fuck. Sorry, pardon my—oh _fuck_. Where did you learn to do that??”

I looked down at my brother in shock. He’d gone a bit fast at first, but suddenly it was as my virgin brother had been replaced with a natural Casanova. Without needing instruction, he’d begun fucking me with one finger, and as he looked up at me with a grin, he slipped a second finger inside me, his other hand circling my clit the whole while. I was wetter than I could ever remember being, and as he started steadily pumping two fingers in and out, my eyes rolled back and I could feel my juices start to gush.

“Oh Jesus, Craig! Oh fuck, yes, just like that—oh yes, keep going. Oh pleeease, yes, fuck me. Oh, fuck me fuck me fuck me fuck me fuck me.”

My hips started uncontrollably thrusting, raising my bare ass off the bed. My brother was a fucking pro—his gloved fingers felt amazing inside of me, and as if he’d read my mind, he’d started to slowly increase the pressure on my clit, drumming his fingers slightly as he did. My whole body felt like it was throbbing, and the pleasure coursing through me was insane.

“Fuck! Oh yes, Craig, fuck! Please! Don’t stop! Oh fuuuuuuck.”

Too late, I realized how loud I was being, and as my orgasm washed over me, I crammed an entire fist inside my mouth, just to prevent myself from screaming out with pleasure. Since I’d first discovered self-pleasure, I hadn’t gone this long without cumming, and it was incredible. Wave after wave of pleasure crashed across my body, and I felt dehydrated from all the juices I’d pumped out onto my bed.

“Fuck,” I said, after a few minutes had passed and the golden glow had begun to fade. “Fucking hell, Craig.”

“Was that good?” he asked, a hint of nervousness present in his voice.

“Brother,” I replied, “that was amazing. Fuck. Pardon my language, but…”

“It’s fine,” he laughed. “I’m just glad I could repay you.”

“Uh huh,” I said languidly. Sleep was beginning to wash over me. “Thanks, Craig.”

“No worries,” he said, taking off the gloves and throwing them into the trash. “I’m going to be honest, it’s going to be a challenge, preventing myself from…y’know. After that.”

“It’s okay,” I said with a yawn. “If the need strikes, you know where I am…”

I was asleep before I realized what I’d offered, but fortunately my earlier efforts had been enough to satisfy Craig, and I slept the rest of the night uninterrupted.

* * *

The next day, when I got home, I was surprised to discover Mason DeGraves waiting outside the house, in a car that looked like it cost more than my Dad had made in a lifetime working at the bank.

“Lord DeGraves,” I said when he opened the car door to greet me.

“Get in,” he said, and I felt like it would be a bad idea to disobey him.

He was sprawled out on the back seat—driving the car was a woman who rivaled his maid for sheer attractiveness. She was sitting down, so it was hard to tell, but I’d guess that she was more than six foot tall—an Amazon of a woman. No, not an Amazon—a Valkyrie.

She had long, blonde hair, and was wearing an erotic parody of a chauffeur’s outfit. It was red and black, with a jacket that highlighted her incredibly impressive cleavage. It was topped off with a small hat, but as I got in, I noticed her bare legs. That made me look closer, and as I peered over the divider, I could see that she didn’t seem to be wearing anything on her bottom half.

Lord DeGraves must have seen my look of shock, because he waved it off casually with an explanation that he was offering her six hundred thousand to drive him around for the next three weeks.

“I told her she could wear whatever she liked for two hundred thousand, or an outfit of my choice for six. She decided the four hundred grand was worth a bit of discomfort…and you are uncomfortable, aren’t you, Lyria?”

The driver—Lyria, presumably—didn’t respond, but when I looked closer, I saw that she was twitching slightly in her seat. She kept shifting her weight in a way that caused her legs to rub together, and I swear her hand looked like it wanted nothing more than to dip between her legs…but when she noticed me looking at her, Lyria straightened up and tried to stay as still as possible.

The old man offered me a drink…and even though I was underage, I decided to take him up on it. A part of me was hoping that I could turn this into some kind of blackmail material…but mostly I just wanted a drink.

“Now, Petra” his Lordship said, smiling as I made a face at the taste of the whisky. I’d sneaked a drink a few times before, but this was…different. Smoother, somehow.

_I suppose that’s the difference between cheap and expensive alcohol_ I thought, before taking another sip and turning my attention back to Lord DeGraves.

“How’s the experiment been going so far?”

“Good,” I replied coolly. I had no intention of lying to Lord DeGraves—the threat he’d delivered at our last meeting had really stuck in my mind—but I wasn’t going to volunteer any information, either. In fact, I’d made some careful decisions so far, ensuring that I could be totally honest and still keep DeGraves completely in the dark.

“Good?” he said, that ever-present leer on his face. “Come, now, surely there’s something to report.”

“I haven’t touched my brother,” I said, trying to keep my face as blank as possible. “And he hasn’t touched me.”

“Ah,” he replied with a grin. “So you’ve pleasured yourself, and I get to keep my money?”

“Nope,” I said, and that seemed to shut him up. He stared at me suspiciously, his eyes narrow, his tongue darting across his lips.

“Let me get this straight,” he asked, and I prayed that he wouldn’t ask if we’d gotten off in the 15 days since this ordeal had begun. “You haven’t touched your brother sexually, and he hasn’t touched you.”

“Correct,” I answered, in what was technically complete honesty.

“Nothing of his has come into contact with you?”

“Nope,” I instantly replied, and immediately regretted the word slipping out of my mouth. I’d forgotten about the culmination of our first time “helping each other out”—Craig had cum, completely by accident, all over my face. No matter how you spun that, it was instantly apparent to me that I’d lied.

In those few seconds, I faced a difficult choice—should I come clean? Technically I hadn’t broken our agreement—the papers we’d signed simply dealt with masturbation, a promise not to orgasm by any means other than each other. They’d said nothing about keeping the old man up-to-date.

But Lord DeGraves had warned me not to lie, and I had. If I came clean, perhaps he’d be generous…of course, what was the worst he could do? If I came clean, I’d be forced to tell him the whole story, a prospect I didn’t relish. I may have been living the old man’s sick fantasy, but that didn’t mean I had to share the details with him.

I made a quick decision to keep quiet. Admitting to a lie wouldn’t help me, and would lead to this creepy, leering old man knowing far more about my nighttime activities than he had to. No one knew what Craig and I had done, and I wanted to keep it that way.

No one ever had to know.

To my credit, I don’t think anyone who saw me in that moment would have known what had just gone through my head. Lord DeGraves seemed satisfied, and allowed me to exit his car without any further questions. Before I could walk inside, however, he called me over to the window, and as I leaned in I saw his driver’s hand twitching again, slowly trying to make its way between her legs.

“You wouldn’t lie to me, would you Petra?”

“No,” I replied, and his lips curled with glee.

“Because if you lied to me…”

His hand shot out and grabbed my face, so quickly I couldn’t react. He held my jaw in a vice-like grip, and leaned in close.

“…I’d have to make your life much, much more difficult.”

My eyes widened in shock as his face contorted into an evil visage—I swear I saw flames flickering in the depths of his pupils, and his forked tongue flicked into my ear, dripping poison. His wrinkles were so pronounced, a face full of mountains and valleys—people starved in those valleys, and those who tried to climb the mountains were punished, thrown to the vultures, pecked to death while still falling…always falling.

His nostrils flared, so wide that I could feel myself being sucked into them, hairy black holes in the centre of his face. His big, bushy eyebrows were covered with the tiniest women I’d ever seen, busty, naked and oiled, each one frantically humping a follicle of his eyebrow-hair, desperately needing to get off, but utterly unable to. And his teeth—they were yellow, crawling with mites, and the mites turned to look at me as I fell into his mouth, my limbs sucked off by the force of his nostrils.

As Mason DeGraves consumed me, I could feel the poison he’d left dripping directly into my brain, rewiring my thoughts, feeding on the perversity that was already growing. I tried to scream, but the ball-gag in my mouth prevented me from being able to do anything—I was entirely at his command, DeGrave’s slave to use as he liked—I’d wronged him, and now I belonged to him…

“We wouldn’t want that now, would we?” his Lordship asked, a mild grin on his face. I blinked in confusion—the vision cleared, and I was standing on the sidewalk outside my house. I’d just been asked a question.

“No, sir,” I answered, slightly stunned by the vision that had just popped into my head as he spoke.

“Do keep me updated,” DeGraves said, and with a gesture the window closed, and the limo drove off.

I stood outside my house for a long time, rubbing my cheeks—they were slightly sore, as if someone had been holding my face. But there was no one there…I hadn’t seen anyone since I’d finished work.

After a while I shrugged it off and went inside, I felt lightheaded, and slightly uneasy, but I passed that off as the result of my busy day, and tried not to think about it.

### Craig:

I was doing homework when I heard the knock on my door.

Opening it, I was surprised to find my sister in front of me. After the previous night, when she’d jerked me off for the second time, and climaxed around my fingers, I seriously didn’t expect to see her for a few days.

“What’s up?” I asked, trying to be as casual as possible.

“I want to talk about last night.”

I gulped, let her in, and gestured for her to go on.

“Look, Craig…I don’t want this to be weird. It’s going to be two months—two _months_ , and we’re only on what, day fourteen?”

“Fifteen.”

“Right. Fifteen. We’re barely two weeks in, and it’s driving both of us crazy. I figure we have two options—we can keep on waiting until our hormones take over before coming to each other, or we can acknowledge that we’re both normal, healthy adults, and that means that yeah, we have sex drives.”

I blinked twice, trying to understand what my sister was saying.

“So, look, as tempting as the thought of spending three days going nuts and then another feeling guilty is, I think we should get ahead of this thing.”

“Petra…” I replied, not quite sure what to say. “Are you suggesting we…”

“Yes,” she said, looking me coolly in the eyes, understanding my question before I even finished it. “I’m saying that when you’d normally feel like jerking off, just let me know…and I’ll do the same.”

I’ve got to admit, I was pretty stunned. I mean sure, since we started this whole thing, Petra had been the rational and prepared one, but something felt really weird about this. She was so…calm.

Millions of guys would probably have killed to be in my place—my sister was basically giving me free hand jobs for the next 6 weeks, but you’ve got to understand—no part of me _wanted_ this. Sure, when I was insanely horny, the sight of my sister’s face covered in my cum had been a weird sort of turn-on, but rationally, I knew that what we’d been doing was wrong, and I wanted as little of it as possible.

And not the hot kind of wrong, either. The “eccentric billionaire with a weird hard-on for incest forcing us into it” kind of wrong, and believe me—there’s nothing sexy about that.

“Uh, okay sis…” I stammered. “I really appreciate the offer, but, um…yeah, I’m not really feeling it right now. Thanks, though?”

Petra laughed, and pulled me in for a hug.

“I appreciate the honesty, little bro, but…well, I wasn’t here for you.”

For once it took me a few seconds to work out what she was talking about, and then I connected the dots.

“Oh.”

“Unless you think there’s something wrong with my plan, of course.”

“No,” I replied immediately. I mean, I didn’t want my sister to get the wrong idea—it was strangely important for her to know that I was a team player, not a selfish layabout who wanted to use her for sex without giving anything back.

As well as that, my experience last night had been the first time I’d ever actually touched a girl…down there. And even if it was my sister, I had to admit—I was keen to repeat the experience. Judging by her reaction, I’d gotten the hang of it pretty quickly, and I really wanted to cement my learning.

Somehow, fingering my sister didn’t trigger off the same weirdness in my brain that I felt when _she_ touched _me_. I guess it was because I was able to focus entirely on her pussy, to the point where it could be anyone’s…as well as that, since I wasn’t actually getting any physical pleasure out of it, I didn’t feel bad about what we were doing.

I don’t know exactly how my brain worked in this situation—it wasn’t exactly something I’d ever expected to come up—and so I agreed to help her. After checking to make sure that our parents weren’t likely to come up any time soon, I shut the door to my bedroom and put on the glove that Petra offered.

“Now,” she said, removing everything below the waist, “you did pretty good yesterday, so I’m keen to see how you go without direct instruction.”

“Sure thing,” I replied, adding a squirt of lube to my hand. “Let me know if I do anything particularly wrong…”

* * *

Ten minutes later, I smiled proudly as, once more, my sister’s pussy clenched around my hand in orgasm. There was something so satisfying about getting a girl off; I don’t know if all of them were so loud, but it was pretty freaking rewarding when Petra had to clamp her hand over her mouth to prevent our parents from hearing her cries of pleasure.

“Wow,” she said a few moments later. “Craig, I…wow.”

I didn’t say anything, just nodded curtly. The more sexual contact we had, the more my confidence grew…the old Craig would have thanked her profusely and asked for feedback, but now that just felt pathetic.

“Well,” I said with a yawn, “it’s been good, but it’s probably time for bed now.”

“Craig…” she said, looking at me with a crooked smile. “Come on. What did we just talk about?”

My mind was a blank, and so I just stared at her as she pulled her pants back up.

“Come on bro, we agreed—if we ignore our impulses, they’re just going to build and build. Let’s make this easy on ourselves, okay?”

“What are you talking about?” I replied, and she gestured to the front of my pants, where my erection was clearly visible.

Oh.

“You really want to take care of this?” I asked.

“Sure,” she said, obviously trying to be flippant and casual…but even as she spoke, she kept on staring at the bulge in the front of my pants.

I raised one eyebrow, but she didn’t even notice. What the flip was going on with my sister? I couldn’t deny that getting her off had turned me on—bringing a hot girl to a screaming orgasm will do that to any male, yeah?—but her behavior was creeping me out just a little.

Still, I couldn’t deny—I was horny, she was there, and if I didn’t let her do it, there was a decent chance I’d succumb to temptation before I went to sleep. And so without a word, I pulled my pants down and let my boner spring into view, trying to ignore the smile on her face as it appeared.

She pulled out a second pair of gloves from her pockets— _She really does come prepared,_ I thought—and sat me down on the bed. I wanted to shut my eyes while my sister lubed up her hand and crawled in-between my legs, but there was something about her fixation that…you know what? Fuck it, it was hot.

I hate saying it, and I especially hated seeing it, but at the same time—any girl staring at your cock like it’s a hugely valuable prize is going to be a turn-on, so rather than shutting my eyes and picturing Alison Brie, I just watched my sister as she slowly pumped my cock.

We’d been going for a few minutes when a thought struck me.

“No condom?” I asked.

“Don’t worry about it,” she replied.

“But what about…—“

“Don’t _worry_ about it,” she repeated, and so I didn’t.

It wasn’t more than a few minutes before I was ready to blow, and so I grunted a few words of warning. Tempting though it was to blow my load on her face again, I couldn’t do that to her (especially if she started screaming) and so I let her know with plenty of time to stop, or put a condom on, or whatever her plan was.

To my surprise, as my hips started involuntarily thrusting forward, she leaned forward, took the head of my cock in her mouth, and looked up at me with those big, brown eyes of her.

“Oh fuck,” I panted. “Petra…”

Having just cum the previous night, my load wasn’t nearly as large as it had been the last two times, but she still seemed to struggle with it, choking slightly as the third string of cum propelled from my dick and hit the back of her throat.

After a few seconds of gasping and spluttering, she collected herself and swallowed loudly.

“Petra!” I gasped in shock.

“What?” she asked defensively, licking her lips. “Oh come on—I didn’t have a condom on me, and it’s way easier than cleaning it all off. Besides, I’ve never had a problem with swallowing.”

There was a long pause, as I just continued to stare.

“…I kind of like it,” she finally admitted in that soft voice of hers. “Anyway, time for bed. Look, Craig—if you want to make this weird, we can make this weird. I’m just trying to be practical—we both have needs, and we both have ways of servicing those needs, so what’s the big deal? It’s not like we’re fucking.”

A part of me wanted to argue that yeah, swallowing your brother’s seed was definitely in the same arena as sex, but she was right. It was only as weird as we made it, and so I just thanked her, shut the door, and lay on my bed, staring at the ceiling in thought.

* * *

The next day was a Saturday, and both our parents were out. I was watching a movie in my room when she knocked on my door.

“Yo,” I said, and she pushed my bedroom door open. “What’s up?”

“I need your help,” she said nervously, and the emphasis she put on ‘help’ told me exactly what she meant.

“For real?? It’s been like twelve hours…”

“Yeah…I should probably have told you this before, but I have a pretty high sex drive. If that’s going to be a problem, let me know.”

What could I say? ‘Yeah, sis, your libido is causing me anguish. Sort it out, except don’t, ’cos then we lose four million dollars. Oh, and I’ll still come to you for a handy whenever I want.’

And so I let her in, got her off, and when she noticed my erection, let her jerk me off again as well.

She came back again that night.

This continued for the next week. At least once a day, I’d finger my sister to orgasm…most times, I’d let her jerk me off as well. After that first time, I never brought up the condoms again—she seemed happier swallowing it, and I had to admit, it felt way better without the rubber. Even when a condom packet dropped on the floor as she pulled the gloves out one time, neither of us said a word.

As we approached the weekend, she started using her mouth earlier and earlier, too. To start with, it was always her gloved hands, but as I got closer to cumming, she’d start putting her mouth on me, until the feeling of her lips over my head was what was making me cum in the first place.

At first I felt super uncomfortable with how things were progressing, but except for those little things, Petra seemed so…normal. I figured it wasn’t worth bringing up—after all, we weren’t doing anything _wrong_.

Until that Friday night. We were on the living-room sofa, and my fingers were lazily pumping in and out of her. Seinfeld was on, and we were both kind of watching it as we fooled around—when she asked if I could use my tongue.

“Petra!” I exploded. “What the hell are you talking about??”

“Oh come on, Craig…please? It would feel so good…”

“No! I’m not…ew! I can’t believe you’d ask me to do that!”

I shuddered, and pulled my fingers out of Petra’s pussy. She sat up, annoyed, and glared at me.

“Oh come _on_! I’ve been practically sucking you off for a week! If you’ve got such an issue with siblings tasting each other’s genitals, you’ve had plenty of chances to mention it!”

I stood up, suddenly furious.

“I never asked you to do that,” I said in a dark hiss, moving my face closer and closer to hers. “I don’t know what kind of game you’re playing, but I _never_ asked you to do _that_. How dare you?”

A look of terror crossed Petra’s face, and I suddenly realized how aggressive I was being. Without even noticing, I’d grabbed her wrists, and had her pinned on the sofa below me. The look of fear was replaced by a sudden tremor of arousal, as if she found my dominance somehow sexy…but no, I couldn’t let myself believe that. I just couldn’t.

There was a long silence, until Petra’s small, sad voice broke it.

“I’m sorry,” she said, and my heart melted…as I’m sure she knew it would. “I just get so turned on, and it’s just been so long.”

“I’m sorry too,” I said sincerely, before firmly adding “…but I’m not doing…that. I can’t.”

“Not down there, of course not. I understand. But look, how about a compromise?”

My sister slithered out from underneath me, and slowly began removing her top. You’ve got to understand, in all the time we’d been doing this, she’d only ever been bottomless—I’d never seen her completely naked. Hell, I’d never even seen her in a bra before. And so I couldn’t help but stare as she slowly stripped out of her sweater, to reveal her bare breasts beneath.

_Has she been braless all day?_ I wondered, before I really registered what I was seeing.

Other than porn and statues, I’d never seen a woman’s breasts before, and when Petra took my hands and placed them on her tits, I was unable to resist. I started pulling and tweaking, and Petra responded by moaning in pleasure.

“Shhh,” I said with a giggle. Our parents were out, but we needed to get into the habit of being quiet. We still had a long five weeks ahead of us.

“Suck them,” she whispered. “Please, Craig…I understand if you won’t go down on me, but use your mouth on my nipples. Please.”

A part of me insisted that it was wrong, but the offer was too alluring to pass up on, and so I leaned in to taste my older sister’s nipples for the first time.

I lightly nibbled them, I sucked, I ran my tongue in circles around her teats—everything I did caused ripples of pleasure throughout her body, and when my hand returned to its duties down under, it wasn’t long before her fidgeting turned into uncontrollable spasms of pleasure, as she came harder than I’d ever seen her cum before.

“My turn?” she asked, and I just nodded. She didn’t put her clothes back on, just moved down and started sucking my cock. There was no pre-text of a hand-job, not this time—she just took my member in her mouth, and went to town. Whatever didn’t fit in her mouth she’d jerk off…what we were doing was so hot, so taboo, I was tapping her shoulder in warning less than two minutes later.

Instead of speeding up, however, she pulled me out of her mouth, and with a wicked grin asked me a question I never thought I’d hear my older sister ask.

“Want to come on my tits?” she said, and though I was too shocked to answer, she took my silence as a yes, and furiously continued to jerk me off.

All I could do was watch as my engorged head began spewing cum onto her firm, beautiful tits—she aimed carefully; the first spurt hit her right breast, the second her left, and she moved herself so she could take the final dribbles of cum from my spent cock directly onto her smiling face.

“Thanks, bro,” she said, cleaning her face off with her tongue and massaging my jizz into her tits. “I’m going to go have a shower, if you want to join me.”

I didn’t. As I came down from my exquisite, incestuous orgasm, my mind was racing.

What the hell had happened to my sister?

* * *

Lord DeGraves smiled as he saw Craig traipsing across the sidewalk, obviously deep in thought. A honk of his limo’s horn caused the teenage boy to be startled out of his reverie, and when the old man got out, Craig stared at him in shock for a few seconds, before his eyes lit up in fury.

“You!” he bellowed. “You did this to her! What did you do? How the fuck did you do it? You’re going to pay, old man…”

As Craig began rolling up his sleeves, Mason DeGraves just laughed.

“Come with me,” he said, moving up the street at a brisk pace. “Hear me out. If you still want to hit me, you can…but first, I want to show you something.”

Unsure whether to follow the old man or just tackle him, Craig stood in angry indecision for a few seconds, before shaking his head and storming up the street after him.

Lord DeGraves slipped into a small bakery that Craig had never noticed before.

“Cupcake?” DeGraves said, as Craig sat opposite him. In reply, he just got an angry glare, which he again responded to with laughter. “Trust me, have a cupcake. Trish, three cupcakes!”

“Three?” Craig asked, before he could stop himself.

“Trish is going to join us, aren’t you?”

“Of course, Lord DeGraves” the baker said in a honeyed voice, and Craig looked up to see the proprietor of the small business enter from the back room.

She was a tall, full-figured black woman, with long braided hair, and a smile as white as snow. She was dressed like a Swedish beer wench—a short, frilly blue dress that showed off her knee-high white socks, and more than a little of her cleavage. It contrasted her dark skin-tone, a strange clash that caused Craig to boggle.

“I, uh…”

“Here,” Lord DeGraves said with a smile. “Try the cupcake.”

Trish held it out, and without even thinking, Craig leaned forward and took a bite, trying with all his effort not to fall into the expanse of black cleavage in front of him.

“Now, I can tell that you’re mad, aren’t you?”

“You bet I am,” Craig replied, but without the vigor that he’d intended.

“If it weren’t against the contract, I’d get Trish here to take you to the back room and calm you down, but instead I’m going to recommend that you take another bite of the cupcake, cupcake, and I’m going to explain a few things to you.”

The old man talked for a long time. It could have been hours, for all Craig knew—his attention was almost entirely focused on the gorgeous black woman in front of him. Every time she giggled, her bosom bounced delightfully, and each time he tried to divert his attention back to the old man, she’d move a hand onto his leg and just toy with the fabric of his jeans for a few seconds.

It was most pleasant and most distracting, and pretty soon the sun had set, and Craig noticed that more than a dozen cupcake wrappers sat in front of him.

“Where…where am I?” he asked, looking around. He was sure that he’d come here with someone, but he couldn’t recall who.

“I’m Trish,” the beauty in front of him said with another dazzling smile. “You’re at my bakery. You’ve been spoiling yourself…”

“Haha, yeah, I guess I have. Uh, how much do I owe you?”

“Oh, honey…” she replied with a pout. “It’s on the house. Now you should be heading home…I bet that you’ve got someone special waiting for you.”

“Yeah,” Craig replied, still slightly dazed. Brushing the crumbs off his shirt, he began to leave.

Trish smiled as the young man left her store. He looked so intelligent, yet he hadn’t even taken a second glance at the big plaque behind the counter, thanking Mason DeGraves for his financial contributions toward the small bakery.

“I hope he finds what he’s looking for,” she muttered to herself, before popping a cupcake in her mouth, and wondering if Mason would be visiting again soon…for pleasure, instead of business.


	Chapter 4

### Petra:

I was painting my nails when my brother barged in. Normally he’ll knock first, but today he had a strange look in his eye.

A look that suggested he wouldn’t take no for an answer.

Of course, so far, no had never been my answer. I told you—when I’ve got regular contact with a dick, I just get so _horny_ , and even the fact that it was my brother’s hadn’t slowed me down. I’d come home one day with a startling revelation—the more we fought against our urges, the harder it was going to get. The only way to beat this thing was just to do what we had to do—use each other to get off, at every opportunity.

And so I’d started going to Craig every time I was turned on (which, as I mentioned, was a _lot_ ) and not leaving until I’d jerked him off.

Something about holding a cock in my hand is so fucking _sexy_ , and the only thing that would have made it better was taking it in my mouth…

So…I had.

I’d started by just swallowing his load (another of my favorite things to do) but the more I got to hold it, the more I wanted to taste it. Pretty soon, I was putting Craig’s cock in my mouth at the earliest opportunity.

Last night…last night I may have pushed it too far.

Craig, of course, was so nervous about the whole “incest” thing. I, on the other hand, had managed to convince myself that it wasn’t incest, it was just two people in need getting each other off.

My kid brother, he wasn’t as level-headed about the whole thing.

I tried not to push it, I tried to move at a pace that he was comfortable with, but last night I just said fuck it—I was horny, and he was the only way I was going to get off.

He’d freaked out, of course, and so I’d tried to mollify him with some boob action. What guy doesn’t like breasts, am I right?

Well, after that, he was so turned on that I didn’t even pretend to start with a handy. I just took his cock in my mouth, and gave him the best blow-job I know how to give.

A few minutes later, he was blowing his load on my tits. Fuck…I’m getting turned on just thinking about it. Why is it so hot, having a guy blow his load all over your body? There’s something so masculine about it—like he’s marking you as his property or something.

Anyway, he’d avoided eye contact with me all morning, and so I couldn’t help but be excited when he burst into my room that night, a fierce look on his face.

“Get up,” he growled, and I eagerly obeyed.

I don’t know what had gotten into Craig, but he looked…

Furious wasn’t the right word for it. No, he didn’t look angry, he wasn’t mad, he just seemed to be so…so…

Assertive. Dominant.

A thrill ran up my spine at the thought of Craig dominating me, and I missed what he said.

“Pardon?” I asked politely, and he rolled his eyes and sat on my bed.

“Sit,” he said, and when I went to sit next to him, shook his head.

“Not there.”

I hesitated, and—clearly impatient—Craig pulled me onto his lap, bending me over like a child.

“Look,” he hissed into my ear, “I don’t know what you thought you were playing at last night, but that wasn’t on, okay?”

“Um…” I replied, and he sharply swatted my behind in response.

I’d never been spanked as a kid, but some of my ex-boyfriends had been really into it…and so had I.

“Oh!” I squealed.

“Now listen,” Craig said. “This _isn’t sex_.”

He continued to spank me as he spoke, and I grew wetter and wetter.

“This is just two people helping each other out, okay? Don’t even think of us like brother and sister. I’m just a man, and you’re just a woman. And what were women designed to do?”

I was too busy moaning with pleasure to answer.

“What were women designed to do?” he repeated, punctuating each word with his hand on my butt.

“Pleasure men,” I panted in response.

“That’s right,” he said, standing up and depositing me on the floor. I looked up to the delicious sight of him lowering his pants, his hard cock coming into view.

Neither of us said a word—he just grabbed me by the hair and guided my mouth to his cock. I took his hardness inside my mouth, and enthusiastically did all that I could to get him off.

He treated me as if I wasn’t even a person, as if I were just a wet hole to be used for his pleasure, fucking my face as hard as he could. I felt so dirty, so used…and I loved it. Before long, he was cumming in my mouth, and when we was done, he picked me up and threw me on the bed.

I watched, wide-eyed, as he spread my legs, flipped my skirt up, ripped my panties off, and dove in-between my legs, fucking me with his fingers, and then leaning down to use his mouth on me.

“Craig!” I cried in pleasure. “But…I thought…”

“Shut up,” he said, withdrawing his hand and spanking me neatly on the pussy. “I told you—we’re not brother and sister. If we go down that path, we’ll never get through this month. We’re just a man and a woman with a convenient arrangement, okay?”

“Okay,” I said with a whimper of pleasure. My mind was spinning—if we were treating each other like strangers, did that mean we had to stop at just oral? Could we…

Ew. As much I’d become comfortable with what we had done up until now, _that_ was too far. I pushed the image from my mind, and focussed on the sensations that Craig’s mouth and hand were causing on my soaking pussy.

Actually having sex? That was wrong. It was crossing the line. It was something we could never do.

So why couldn’t I stop thinking about it?

* * *

Before he left my room that night, I insisted on going down on Craig once more. After all, it was almost 9pm…I wouldn’t get another chance to do this all night, and I didn’t want _any_ risk of him slipping. There was too much at stake.

The next morning, I got up and sneaked into his room to wake him up with another blow-job. Like a gentleman, he insisted on returning the favor, and that pretty much described the whole week. Once or twice a day, my brother and I would find each other, and ensure that we weren’t dancing with fate, letting our hormones build up.

And get each other off.

All weirdness had passed by this point—the idea was firmly cemented in both our heads that this _wasn’t_ incest, it was just two people helping each other out. The fact that we were brother and sister was irrelevant—I was just a woman, with the soft curves and wet holes of a woman, and he was just a man, with the hardness between his legs that every woman craved.

Admittedly, our sibling connection was probably part of why we were able to read each other’s bodies so well—I swear, Craig knew _exactly_ how to turn me on. I’d admitted to him how hot I found spanking, and before he went down on me, he’d often start by using his hand on my ass until it was glowing red and I was dripping.

We continued to elude Mom and Dad without issue, although Craig would sometimes push it a bit. I’d have complained, but I found his daring so sexy…one time, we were sitting in the back seat of the car together when he reached over and pulled my hand onto his crotch. Another time, he excused himself early from dinner, and then texted me to come meet him in the bathroom a few minutes later. I pretended that it was a friend I had to call back, and quickly joined him. A few minutes later, I was gulping down his cum.

A few times we got naked together—Craig’s got a surprisingly good body, and I fucking love how it feels when he runs his hands all over mine. At first I let him play with my tits because I knew _he_ enjoyed it, but pretty soon, I was just as into it as him…if it wouldn’t have made things weird, I’d have taken off all my clothes every time we got together.

Then one night (about two weeks after the night he spanked me for the first time) we had a sort of a…moment. We were both naked, laying next to each other on his bed, just sort of casually playing with each other’s genitals…it wasn’t a high-pressure “must make each other cum” kind of situation, we were just letting off a little steam.

I was slowly stroking his cock, he was running his fingers up and down my pussy-lips (I’d started to shave, just to make sure going down on me was as easy as possible) and we were chatting about our day.

As things got a bit more heated, we both got quiet, and soon we were just laying there, looking into each other’s eyes. I started pumping up and down his dick a little faster, he slipped a finger into me and watched my mouth with a smile as I moaned.

Somehow, our bodies started to get closer and closer…until soon, my hand was coming into contact with my own stomach every time I pumped, and I could feel the heat of his chest against my breasts.

We were both getting closer and closer to cumming, and then it happened…

He leaned in and kissed me.

Now I should clarify—Craig had _never_ kissed me before. I guess we’d both silently agreed it was too intimate, but there was something about it, the feeling of his tongue in my mouth, his stubble on my cheeks, the knowledge that he was my brother…it was fucking hot.

And so I kissed him back.

As I did, we froze. Every muscle in my body went tense, and I could feel his do the same. I kept my hand on his junk, and he still had two fingers inside my pussy, but neither of us were moving…just laying there, completely still, not sure what to do next.

Finally, I pulled away, and opened my eyes to see him looking back at me…not in fear, just casually, coolly seeing how I was going to react.

I considered running, or pretending nothing had happened, but then I remembered my mantra.

_It’s only as weird as you make it._

Unable to stop myself, I giggled, and practically melted with relaxation as I saw a slow smile spreading over his face as well.

“That was hot,” I said frankly, and he just grinned and nodded.

Letting go of his dick (reluctantly) I put both my hands on his face and started making out with him again. He put both his hands firmly on my ass—not as good as my pussy, but I certainly wasn’t complaining.

We just lay there for ages, macking on each other. It had been so long since I’d had a boyfriend, and everyone kisses differently…I’d missed tasting the new tastes, enjoying the idiosyncrasies. Every now and again, for instance, my brother would nip at my lip slightly as we kissed, which I _loved_ , and soon I was straddling him, one leg on either side of his prostrate body, kissing him passionately, wondering if he could feel the heat emanating from my pussy.

And that’s when it happened. That’s when things got weird.

I was getting more and more turned on as we made out, and when I’m turned on, I tend to…thrust, slightly, I guess. Well there I was, naked, on top of him, and as I thrusted, my pussy came into contact with his erection.

It felt _amazing_. It was just the slightest of slight brushes, but it was like a bolt of electricity travelled between our bodies. I gasped with pleasure, and—heaven help me—went to do it again when we both realized what was happening.

We were almost fucking.

I pulled back in shock, and even my normally-unflappable brother was staring at me, wide-eyed.

There was a long silence, and I could tell that this time…we wouldn’t be breaking it with laughter.

“I should…”

“Yeah.”

Nothing more was said as I gathered up my clothes and left for my own bedroom.

Up until then, the second week of DeGraves’ challenge had been the trickiest. My hormones had started to take over, I’d started to see everything as sexual, and it had been a genuine struggle to stop my hand from slipping between my legs at night.

But that night, as I got back to my own bed, sexually unfulfilled for the first time in weeks, I almost gave up the full four million. All I wanted to do was touch myself, get it out of my system…but since I couldn’t, I just tossed and turned, the image of Craig fucking me running through my mind over and over, getting me far more hot and bothered than I felt comfortable with.

* * *

Despite getting hardly any sleep, I awoke early the next morning, and immediately knew what I had to do.

I had to go in and wake Craig up with a blow-job. Partially, to remove any temptation he might have to touch himself, but more importantly—to ensure that things went back to normal between us.

You know, where “normal” is defined as pleasuring each other whenever we’re horny.

_Fuck you, DeGraves,_ I thought, grumbling, as I put on a set of lingerie that I knew Craig would like. _Why can’t you just be a normal billionaire? Why do you have to play with people like this?_

Making sure the coast was clear (getting caught sneaking into my brother’s room in Victoria’s Secret underwear would, I knew, be pretty hard to explain) I made my way onto Craig’s bed and lifted up the covers…

And as I did, I saw a truly horrifying sight.

As he’d slept, his hand must have drifted into his underpants. His dick was still hard, but softening—his hand was resting on it, and his underpants were wet.

From the incredibly familiar smell, I could tell that he’d only just cum.

“Craig!” I said in shock, making sure to not be too loud.

“Oh, fuck…” he said when he awoke saw what he’d done. “Oh, _fuck_. Fuck fuck fuck! Does this count??”

I tried to remember the exact wording of the contract that we’d signed, but I couldn’t. For a brief moment, I was furious.

“What the _fuck_ , Craig? How could you do this?”

“How could I do this?” he replied, sitting up and staring intensely into my eyes. “This is your damned fault—I dreamt all night about your little escapade last night. I couldn’t close my eyes without thinking about how good it felt, about how much I wanted to…”

He trailed off, and—not for the first time—I wondered what was wrong with me. Why did I find that strength of character, that dominance, so…so…

I took a deep breath, trying not to think about what he’d just said—or how much how he’d said it had affected me—and replied as calmly and rationally as I could.

“Look, it’s no one’s fault. I’m sorry for winding you up…we’ll just have to go see Lord DeGraves, and see what he says.”

“Fine,” Craig said, avoiding eye contact.

“I’ll make an appointment.”

* * *

The earliest DeGraves could see us was the next morning, and Craig and I avoided each other’s company until then. I knew we were both turned on—well, I knew that _I_ was turned on, and I couldn’t imagine that my brother wasn’t—but it was too awkward…we didn’t want to risk using each other to get off needlessly. If it turned out that we’d already lost.

After a brief conversation, we agreed not to masturbate either…just in case.

One more almost-sleepless night later, the morning finally arrived. I went in to check on my brother, and was amused to find him laying asleep in bed wearing pajama pants…and a belt. At least he was taking this seriously.

“Wake up,” I said, throwing a pillow at his head.

He woke up, looked around sleepily and glared at me. I would have said it felt just like everything had before the wager, except for the pulse of arousal that passed through me at Craig’s glare.

Our parents let us borrow the car, and half an hour later, we were sitting in Lord DeGrave’s office, sipping the tea he’d insisted we take, waiting for him to get off the phone.

“Fine!” he finally said, rolling his eyes at whoever was on the other end. “Don’t mention horses…just get me a farm girl!”

Slamming the receiver down, he turned his attention to my brother and me.

“Now,” he said with a sickly smile upon his face. “What can I do for you two?”

I opened my mouth, but my brother put his hand on my arm, wordlessly silencing me, and leaned forward.

“Lord DeGraves,” he said confidently—why the hell was that confidence suddenly such a turn-on? He was my brother, for Pete’s sake…

“Lord DeGraves, we’ve got a potential problem.”

“Oh yes?” the old man said, licking his lips with glee. “Knocked her up already?”

“No!” I said angrily, but again Craig silenced me with a squeeze of my arm, and I obediently shut up.

“No, it’s not that. It’s me. I woke up to discover that I…”

“Came in your sleep?” DeGraves said, finishing my brother’s sentence with a cackle. “And it only took you a month!”

“That’s right,” Craig said. “We want to see the contract. We want to know if it breaks the rules.”

“Well…” his Lordship drawled. “I can have a look at that for you, but first I want to ask a few questions.”

“Anything,” my brother said, ignoring the daggers my eyes were shooting in his direction.

“This nocturnal orgasm—is this the first time you’ve cum since you were last in my office?”

“Of course,” my brother deftly lied, and I tried not to let the surprise show in my face. _Well,_ I thought, mentally steeling myself for what was to come. _If that’s the way we’re going to play it…_

“So you two haven’t…fooled around.”

“Certainly not.”

He even managed to sound indignant, and I nodded along.

“Remember, I warned you what would happen if you lied to me…” Lord DeGraves said, and that dangerous tone appeared in his voice once more. Craig, however, held his ground, and I did too. “So let me ask you one more time—in the past month, you two haven’t touched each other sexually at all. No hand jobs, no licking, no sucking, no biting.”

“Of course not,” Craig said, and I shook my head in agreement.

“No…kissing?”

My cheeks went slightly red at that, something that I hoped the old man hadn’t noticed, and when Craig hesitated, I spoke up.

“Lord DeGraves, my brother and I aren’t animals. We’ve done nothing wrong.”

“Well, except the squirt in his sleep.”

“Yes…that’s what we wanted to talk to you about. Does that count?”

“Hmmm,” Mason DeGraves said, placing one wrinkled, old finger on his lips. “I’ll have to ask my lawyer. Petra m’dear, I’ll get you to wait in the garden while I do. Craig, you can stay here…”

* * *

I had no idea why he needed to split us up—I just hoped it wouldn’t be for cross-examination, to see if he could pick any holes in our story. I stepped outside, marveling at the manor’s beautiful garden (why did such a cretinous man have so much money?) and sat on the bench, admiring the flowers.

I’d been sitting there for a few minutes when I jumped with fright—a huge man had practically sneaked up on me. He looked mediterranean—I couldn’t quite tell from where, but his naked torso had the olive skin and swarthy stance of a man from Italy or Greece, or…I don’t know, Malta.

“Pardon, madam,” he said, his voice thick with a sexy European accent that I couldn’t even come close to placing. “I hope I did not to disturb you.”

“No,” I said with a laugh, “it’s fine.”

I blushed, and took a sip of tea to cover it—it had been two days since I’d gotten off now, and it was driving me up the wall.

“I am just to be…trimming the bushes.”

He held out a pair of shears, but I couldn’t stop staring at his chest.

“Of course,” I said. “Let me know if I get in your way.”

The next twenty minutes were, I can tell you, _most_ pleasant. I just sat, sipping tea, watching as Hugo (or Pablo or Mario or whatever his name was) worked…the man was practically a work of art. His huge muscles bulged with every motion, his long dark hair blew in the breeze, and as he snipped away at the bush, a strange sort of pollen started drifting toward me.

It smelled nice, and though I don’t have any allergies, made my mind slightly hazy. As I watched and drank the tea and smelled the pollen, I couldn’t stop thinking about the mostly-naked man in front of me…how attractive he was…how good it would feel if he’d turn around, bend me over the garden bench, and do what my baby brother was too afraid to do…

He was totally absorbed in his work, and it would have been so easy to reach down and play with myself as I watched him, imagined him roughly taking me, fucking me, cumming inside me…

But I didn’t want to do anything rash until after I heard what the lawyer had to say, and so I (barely) managed to stop myself, and just sat there in a delightful haze until I heard the old man’s creaky voice calling for me from inside.


	Chapter 5

### Craig:

I couldn’t help but watch my sister’s ass as she swayed out of the room, to go and wait in the garden. I was so horny—it had been two days since I’d last cum…Petra had surprised me in the shower, and jerked me off until I’d cum on her face.

God I loved cumming on her face. Is that sick? I know it’s wrong, but…four million dollars. I’m sure you can understand.

I glanced over to see Mason DeGraves, the rich fuck who had gotten us into this mess in the first place, checking her out as well.

One month ago, my sister and I had read an ad in the paper, offering four million dollars for two months “work”. Siblings only. We were suspicious, of course, and doubly so when we learned who had placed it. Lord Mason DeGraves, billionaire playboy. “Playboy” is the right word for it, too—he’s older than Howard Hughes, and half as attractive.

He spends his time offering sick wagers to people, and people keep accepting them…because he always pays up. This one was simple—for two months, my sister and I couldn’t get off except by each others’ hand. We’d accepted—of course we’d accepted—and planned to just abstain until the time ran out.

One week later, Petra was jerking me off for the first time. Two weeks later, she was blowing me, and pretty soon after that it became a daily thing.

It wasn’t one-way, either…I’d gotten her off so many times I could recognize her impending orgasms blindfolded. And then the other night, we’d had a weird thing…her pussy had touched my dick.

And it had felt _good_.

Since then, we hadn’t felt comfortable being near each other. I mean, sure, we were “helping each other out”, but mouth and hand stuff…that wasn’t incest. Not really.

Fucking? There was no coming back from that.

To make matters worse, after the genital contact, I’d awoken the next morning to find my hand on my dick and cum in my pants. Did it count if I was asleep? We had no idea, and so we’d gone back to DeGraves Manor to get its owner to look at the contract for us.

He’d sent Petra out into the garden while he called his lawyer…but when she left, he turned to me.

“Last chance,” he said to me. “Have you done anything with her?”

“No,” I said flatly, and he just wheezed and cackled in response.

“Fine, fine! I’ll call Joe. Stay here.”

He left the room, and I sat there wondering what he’d meant by “last chance”. The contract hadn’t said anything about lying, I knew that, so what was he referring to with his vague threat?

And then the door opened, and I began to understand.

“Hey sexy,” a strange voice said, and I turned to see Bethany, the maid that we’d met on our first visit. Once more, she was dressed in an erotic parody of a French maid’s outfit—this time was even more outrageous than the last. Her top was barely more than a bra, and on the bottom half no more than a white apron over a black skirt so short that every time she took a step, it bounced up and revealed everything.

And yes, I mean everything. She wasn’t wearing any underwear, and as she bent over to clean DeGraves desk, I saw everything…including what the old man was trying to pull.

He’d sent Bethany to tempt me. He knew that my nighttime emission didn’t break the contract, and so he wanted to return to find me fucking his maid, just so he didn’t have to pay out.

Well, I wasn’t going to give him the satisfaction. But when I’d first read the contract, I’d mentally made a note of something—my sister and I couldn’t be _touched_ by anyone else…but that didn’t mean we couldn’t do the touching.

I swallowed the last of the sweet, weak tea that DeGraves had insisted we take, and stood up. Bethany was moving her ridiculous feather duster so that it daintily came into contact with everything in the room. Nothing was even remotely dusty, but a strange scented powder floated off the cleaning implement with every swish.

It was sweet, and I paused to inhale it deeply. It smelled nice, like sugar buns, or French toast.

Shaking it off, I stood over Bethany. She was breathing deeply, as if she knew what I was thinking, and in response to me standing behind her, she put both her hands on DeGraves desk.

“Good,” I said in a growl. “Stay like that.”

From the sound of it, Lord DeGraves wasn’t going to be back any time soon, and so I took my time. I reached out and picked up the feather duster, lightly dusting down Bethany’s back, enjoying the sight of her shiver each time the feathers made contact with her skin. She was trembling with anticipation by the time I got to her butt, at which point I put the feather duster down, and began using my hand instead.

With one finger, I lightly traced a pattern up and down her leg, touching her calves, her inner thigh…but never going any further. Finally, when I could tell she couldn’t stand it any longer, I suddenly spanked her ass-cheek, just once. It made a loud “crack” that I hoped couldn’t be heard from outside the room.

“Oh!” she cried, as her skin turned red, and I repeated the motion on her other cheek. “Oh! Oh, please, Master…fuck me! Please!”

“No no no,” I said, spanking her once more, enjoying the look of shock on her face as I did. I leaned in close to her ear and whispered “You’re not going to get me that easily…”

With two fingers, I abruptly plunged the French Maid’s depths, and began fucking her with my hand, using every skill I’d learned from practicing on my sister for the past month. As I did, I whispered all my filthy thoughts into her ear—all the things I wanted to do to her, all the things I wanted her to do to me.

A few minutes later, she was cumming around my hand, quivering and shaking with need. I paused, but it didn’t sound like the call was wrapping up, and so I deftly removed her bra, ordered her to stand with her back against the deck, and sucked upon one of her huge tits as I resumed finger-fucking her.

“Please, sir…please, fuck me! Please, I need it.”

“Hmmm…no,” I replied with a smile. “I’m sorry, but you’re just going to have to try harder than that…”

Five minutes later, when Lord DeGraves re-entered, Bethany had gone back to dusting, and I was sitting on the chair with a smile on my face and a raging erection, as if nothing had ever happened, confident that my actions hadn’t interfered with the contract.

* * *

“Well,” the old man reluctantly said to the young pair sitting in front of him. “Bob tells me that a wet dream isn’t a breach of contract.”

“Bob?” Craig said. “I thought his name was Joe.”

“Bob, Joe…one of the suits. What does it matter? Anyway, you’ve still got plenty of time to slip up. And you will. Oh, believe me…you will.”

After the second cup of tea that Lord DeGraves insisted that they drink, and a song that he’d recently funded he insist that they admire, the siblings got up and silently left the room.

They had barely left the DeGraves mansion before Craig turned up a quiet country road, found a discreet place to stop, and turned to Petra with a hungry look in his eye.

“What?” she said, and then her eyes opened wide and a saucy smile crossed her face. “Oh…”

Craig took her head in his hands, and passionately kissed her. Again, her face was filled with shock before she melted into the kiss, reaching down and unbuckling the belt that her brother had been wearing since he’d gone to bed the previous night.

“What happened in there?” she gasped, as he rained kisses down upon her neck, reaching under her top and removing her bra as quickly as he could.

“Bethany,” he grunted, before reaching up her skirt and ripping her panties from her.

“Craig!” she said, impressed, pulling her top off and allowing her brother complete access to her body.

“Back seat,” he grunted in response. “Now.”

As Craig got out of the driver’s seat and reached for the back door, he tore his shirt from his body and dropped his pants. Then, as Petra joined him, he grab bed her and pulled her toward him. Soon, their naked bodies were pressed against each other, their lips were locked once more, and Petra realized what was about to happen.

“Craig…” she panted. “Should we?”

“Fuck it,” he replied, and she was forced to agree.

Looking back, both siblings would admit that the first time Craig entered his sister was the most erotic moment either of them had experienced up until then. The electricity that they’d felt during their genitals’ earlier, brief encounter was just the beginning—as Craig slid into Petra’s soaking wet pussy, it continued to build and build, growing in intensity and causing them both to be more turned on than they’d ever been.

As the last inch of her brother’s cock slid into Petra, she felt the first of what would be many orgasms crashing over her—she just felt so _full_ , so _complete_ , in a way that she never had before. And when he began to withdraw, the feeling didn’t dissipate—it continued to cause sparks deep within her belly, made her toes curl and her mouth involuntarily fall open with pleasure, and guttural, animal noises to emit from deep within her…

Craig couldn’t believe he was losing his virginity…it felt so good, he didn’t understand why they hadn’t been doing this years ago. He began to thrust into Petra’s shaved cunt, his bareback cock throbbing and pulsating with pleasure at every sensation.

Before long, he could feel his orgasm fast approaching. He gasped a warning into Petra’s ear, and she responded by wrapping her legs around her brother’s body and pulling him deeper into her.

“Cum inside me,” she whispered. “I want to feel you fill me up…”

And Craig obeyed, pumping string after string of his cum inside his sister’s bare cunt. She joined him in orgasm, her eyes rolling back into her head, before the pair collapsed onto the seat. For that brief moment, they were completely satisfied…

And then, after a brief rest, they did it again.

* * *

After that, it was rare for more than ten hours to go past without Craig and Petra finding an excuse to sneak off and fuck. They grew adept at copulating in every possible position—all they needed was five minutes and enough room for two people to stand, and Craig would pump Petra full of his seed as she climaxed around his hard cock.

They spent two weeks in sexual bliss, to the point where even their parents wondered what was happening, why the pair were suddenly so much closer than ever before.

Neither of them brought up the incestuous nature of what they were doing. Any time it felt like the conversation was drifting that way, they’d strip off and make love instead. And after a while, it was definitely making love—Craig would whisper sweet words into Petra’s ear as she came, and she’d set an alarm so she could sleep with him at night, and sneak out before there was any risk of getting caught.

At first, Petra feared that if she stopped wearing panties, she’d be at risk of touching herself and losing the money…but it didn’t take long for her to decide that the risk was worth it, just so she could be as accessible to her brother as possible. If he wanted to use her body, she wanted to make sure that nothing stood in his way.

She’d never admit it to him—she could hardly admit it to herself—but she found two things equally hot about what they were doing. Firstly, that he _was_ her brother, and secondly, that he was using her. Using her for her body, for her cunt, for the orgasms she could provide.

Sure, he loved her—she knew that—but if it wasn’t for the money, he wouldn’t be coming to her every time he was horny…and cumming in her every time he felt the need. The thought became an obsession at times, especially when he was fucking her, and she wouldn’t be able to get it out of her mind.

_I’m being used by my brother,_ she’d mentally chant as he pounded into her as she clenched her pussy in time with his rhythm. _He’s using me to get off…I’m nothing but a cum-bucket for my little bro. As far as he’s concerned, his sister is just a set of wet holes—oh!—and a pair of tits that he can use whenever he likes._

But after two weeks had passed (just 17 days before they could return to DeGraves’ manor and collect their cheque) the honeymoon period began to fade, and the awkwardness began to grow. Craig had no intention of stopping himself from knocking on his older sister’s door whenever he got an erection, but the guilt was slowly returning.

“Petra,” he panted after a particularly lengthy session, two weeks to the day after they’d returned to DeGraves Manor. “What are we doing?”

“What do you mean?” she asked dreamily. She’d cum so hard that she’d begun to see stars, and while she’d never complain, she didn’t much appreciate her brothers’ words bringing her back to reality.

“This…I mean. This is…isn’t it?”

“Incest?” she asked frankly, the wickedness of the word sending a naughty thrill up her spine.

“Yeah…”

“Well, sure. I mean, technically. But I did some reading, and there’s nothing scientifically wrong with it. Not unless…”

“Unless what?”

“Unless you were to, y’know, put a baby inside me.”

Just saying the words made her pussy throb with need. She hadn’t even realized it was something she wanted until then, but the idea had filled her head with lust like nothing else. She wanted Craig to knock her up…she wanted her brother to put fill her with his seed, and breed her like the stud he was.

“Okay,” he replied simply, and she turned to him in excitement.

“Really??”

_That was easy,_ she thought. _I didn’t even have to ask!_

As he stared at her with one eyebrow raised, she quickly realized that she _hadn’t_ asked, and that her brother was speaking about something else.

“Yeah,” he said casually. “I mean, if you’re fine with it, I’m fine with it…and besides, this ass is too good for me to want to stop, y’know?”

“You like my ass?” she said with a smile, and that night, he took it for the first time.

* * *

One week later, Craig and Petra were in the middle of their third round for the day when they heard a knock at the door.

“Shit!” Craig said, almost on the brink of orgasm.

“Mom and Dad?” Petra asked, unwilling to stop bouncing up and down on top of her brother.

“Why would they knock?”

“Fair point.”

Craig ignored Petra’s cries of protests and lifted her off him, and the pair redressed as quickly as they could as the knock sounded again, louder, and more impatient. Petra ran to the kitchen at the opposite end of the house, and Craig opened the door, trying to look as nonchalant as possible.

“You!” he exclaimed.

“Aren’t you going to invite me in?” Lord DeGraves said, a scowl upon his face. “God knows I’ve been waiting long enough.”

“What are you doing here? We’ve still got one week to go.”

“Why do you care?” the old man asked. “Something I should know?”

Craig hesitated, and the old man’s eyes lit up.

“What were you doing when I got here?”

“Housework,” Craig said, and DeGraves rolled his eyes in response.

“Still lying,” he muttered, and before Craig could respond, asked where his sister was.

“The kitchen,” the teenager answered. “I think she was…cooking.”

“Show me where it is, and hurry. I’ve got something I want to tell you both.”

Craig sat next to his sister at the kitchen table as Lord DeGraves closed one eye and stared at both of them. Petra had moved her hand onto her brother’s leg, which made him nervous…even though he knew the eccentric gentleman couldn’t see through the table, he felt as though they were flirting with danger enough just by telling him untruths, let alone flaunting it in front of him.

“So!” Lord DeGraves said, making the siblings jump. “I’m going to ask you this one. Last. Time. It’s been 7 and a half weeks now…tell me. In all that time, have the two of you done anything together?”

“No,” Craig replied immediately.

“No,” Petra echoed, even as her hand moved up to cup her brother’s crotch.

There was a long pause, and a leer slowly formed on Lord DeGraves’ face.

“So,” he eventually said, nodding. “You want to play it like that?”

“Play it like what?” Petra asked earnestly. “There’s nothing to tell, really.”

“I’m going to leave a package here,” the old man said. “Don’t open it until I’m gone.

“I’ll see the two of you next week.”

* * *

Petra and Craig stared at the brown paper package for almost five minutes after DeGraves had hobbled out of their kitchen.

“Should we open it?” Petra said thoughtfully. She’d unzipped Craig’s pants and wrapped her hand around his cock as she always did when she was nervous—just touching it comforted her.

“I guess…” Craig said. “What’s the worst that could happen?”

They went back to staring for a few seconds, before Craig shook his head, and decided to just do it.

“Right,” he said, reaching out and pulling the string.

That was all it needed—the small gift slowly began to unfold, to reveal a small pile of chocolate. The pair stared at for a few seconds, and then—just as abruptly as the chocolates had appeared, they were gone.

Petra blinked twice and looked at her brother in confusion. She could taste the delectable flavor in her mouth, but had no memory of picking a treat up and eating it.

But she must have, and so must her brother -the flecks of brown around his mouth showed that she hadn’t been the only one to sample the treats.

Then the other memories came back.

“Oh my god…” she said, as forgotten thoughts rushed into her head.

“Oh fuck…” Craig echoed, as he remembering the bakery…Trish…the cupcakes.

There was another long silence as the brother and sister let all the memories that Lord DeGraves had blocked out slowly sink back into their consciousness…and the desires that he’d added slowly drift away.

“Oh my god,” Petra finally said, standing up and moving to the kitchen sink. “I think I’m going to be sick.”

“ _You’re_ going to be sick??” Craig asked, staring at her in shock. “I’ve spent the last three weeks fucking my older sister…”

“How do you think I feel?” Petra asked. “I…oh god, I wanted to have your child.”

Before Craig could reply, the queasiness overcame the young woman, and she leaned over and threw up into the sink.

“Oh fuck…Petra. I’m so sorry.”

Petra didn’t reply, just continued to heave and heave until there was nothing left to throw up.


	Chapter 6

Neither sibling got out of bed the next day. They each just lay in their respective bedrooms, staring at the ceiling, remembering what they’d done. The positions…the locations…the sensations. They told their parents that they’d come down with some kind of stomach flu, and it wasn’t until noon the day after that either of them got out of bed.

Craig winced when he heard the sound of a knocking on his bedroom door—the sound that would have had him leaping for joy just a few days earlier now filled him with dread, and when he opened it, he found Petra with a similarly gaunt look on her face.

“Hey,” he grunted, and gestured for her to come in and sit down.

“Hey,” she responded, and the two sat in silence for almost twenty minutes before either of them spoke.

“I’m sorry,” Craig finally said, but Petra just waved it off.

“I wanted it as much as you did.”

They didn’t say anything else, and eventually Petra got up and left Craig alone with his thoughts.

That night, she returned to his door, knocked once more, and waited for him to open it.

“Surprised to see me?” she said sheepily, looking much better than she had earlier that day. There was even the hint of a grin on her lips, though if you looked too closely, it would disappear.

“Well…” he said, trailing off. She didn’t need him to finish his thought.

“Listen,” she said matter-of-factly, once he’d let her into his room. “I figure that what’s done is done, right?”

“Right.”

“That old man did…something…to us, made us want each other. Nothing we could do about it. Right?”

“Right…”

“So we have a few options. We can sit here beating ourselves up over it, or we can just accept that hey—we had sex. People had sex. It happened.”

Craig stared at his sister for a few seconds before responding.

“Where are you going with this?”

“We’ve still got a chance at winning the four million, right? I mean, you still haven’t touched yourself, have you?”

“Of course not,” Craig replied quickly. “How could I?”

He didn’t mention the temptations he’d faced over the last day and a half. Mentally reliving all the horrible things he’d done to—and with—his sister had been devastating. But, even worse than that, as he’d recalled the feeling of her skin on his, the enthusiasm with which they’d fucked, the love that they’d felt…

More than once, he’d found himself getting hard at the memories. He’d dismissed the thoughts that aroused him as quickly as they’d come, feeling incredibly guilty for even thinking that way, but they kept coming back over and over again, until he’d honestly asked himself if it wouldn’t be worth four million dollars to masturbate and just get it out of his system.

“Me neither,” his sister replied solemnly, and there was a long pause.

Craig was about to speak when she startled him by finishing her thought.

“…but I’ve wanted to.”

Neither of them said a word, just stared as they realized where the other was at.

“Oh, fuck…” Craig said, as he realized what his sister meant.

“I know,” Petra replied, and after another long pause, added “…are we bad people?”

“Maybe he’s still…”

“No,” Petra said softly. “I remember what it was like. This isn’t…this is…

“This is just me.”

“Me too,” Craig said.

The pair stared at each other for a long while, until Petra said three words, so softly that Craig barely heard it.

“…four million dollars.”

Craig responded by rising from his bed and taking Petra in a passionate embrace. Their lips locked, even as both of them felt an incredible sense of guilt at what they were doing, what they were about to do.

Petra raised her arms to allow Craig to remove her top, and as soon as it was off, reached down and undid his belt as she had so many times before. His cock came into view, and she realized that the giddiness at the sight of it was gone, she didn’t feel the rush of euphoria, or the secure knowledge that she was doing the right thing.

…she just wanted it, enough that nothing else mattered.

“I’m sorry,” she said, looking up at him with sadness, before leaning forward and taking the entirety of his member in her mouth.

Like riding a bike, it came back to her straight away, and she almost reached down to play with herself at the simple joy of tasting the familiar cock. Of course, that would have defeated the purpose of what they were doing. They were so close…if they used each other just a few more times, just to ensure that the money was theirs…

Petra bobbed her head up and down on it for a few minutes, refusing—unable—to look her brother in the eye. When he was good and hard, she removed it from her mouth, and lay back on his bed.

“Please,” she said softly, and Craig’s inner demons came out to taunt him as he got even more erect at the look of need in her eyes.

“Are you…you’re not…”

“I started taking the pill again,” she whispered, and Craig shuddered at the fact that he even had to ask, before leaning forward and slowly sinking his cock into his sister’s warm, wet, inviting pussy.

The feeling of each others’ touch was hauntingly familiar, and it wasn’t long at all before Craig warned his sister, and she allowed her own orgasm to wash over her before he met it with his.

As they redressed, the siblings avoided eye contact. Both of them knew that they could never do this again, that the physical sensations weren’t worth the lifetime of guilt that they knew they’d feel. This time they couldn’t even blame it on a curse, or a glamor, or whatever the perverted old man had done to them.

This time, they knew it was on them.

They lasted three days before having sex again. _One last time,_ they each told themselves. _Then it’s all over._

* * *

When Petra and Craig walked into the office of Lord DeGraves, they were met with the sight of his naked ass bouncing up and down as he repeatedly thrust into Bethany, who lay spread-eagled on his desk.

“Don’t mind me,” he said gleefully in response to their sounds of revulsion. “I’m almost done…maybe you can go next, Craig-y boy. In just twenty minutes time, you’re a free agent…”

They waited outside until a slightly flustered Bethany fetched them, cum dripping down her leg.

Entering the old man’s office, they firmly turned down his offer of tea, and sat before him.

“Now,” he said, fixing each of them with an intense stare before continuing. “I want to know…anything happen between you two since I saw you last? Don’t lie to me…if nothing else, at least tell me you’ve learned what happens to people who lie to me…”

“Fuck off,” Craig said, and the old man cackled merrily in response.

“I think I’ve got my answer,” he said, clapping his hands. “Right! How would you like to do this?”

The money was underwhelming, when they saw it—enough to fill two briefcases each. They weren’t sure what they’d been expecting—a truck, maybe. They accepted DeGrave’s offer of a bodyguard, and as they were walking out, Craig turned to the old man, slightly red, and asked how much he wanted for Bethany.

“Bethany?” Lord DeGraves said in a high-pitched wheeze. “You idiot, I’d never sell Bethany. She’s worth more than money can buy…she’s a rare gem.”

“Why?” Craig asked, unable to stop himself.

DeGraves gave a slow cackle before he responded.

“Because she’s a natural, my dear boy. I didn’t have to _do_ anything to her…she’s here of her own accord. Always has been. But I’ll tell you what…come around any time and I’ll let you borrow her.”

Ignoring his sister’s glares, Craig walked away from the detestable laugh of Lord DeGraves, and the pair went to deposit the money into the nearest branch of their bank. DeGraves had called ahead so the bank was forewarned and, when they got there, the siblings were surprised by the level of service they got for depositing such large amounts.

Once all the paperwork had been signed, Craig sat next to Petra in the car and sighed.

“This is what it’s going to be like from now on, isn’t it?”

“We can do anything,” she replied softly. “We can go anywhere, be anyone…”

After what felt like a year, the silence was broken by Petra’s soft whisper.

“Craig?” she said, and he nodded in response. “…hold me.”

* * *

After that, it took a long time for things to get back to normal. Normal. What does that even mean?

I’ll tell you what the first thing I did when I got home was: I went into my room, locked the door, and jerked off. She never admitted to it, but I’d bet you one of my two million dollars that Petra did the same.

Breaking the news to our parents was hard. When they asked where we got the money, we told them that we’d done some “work” for Mason DeGraves, and to their credit…they never asked what.

Dad’s a banker, so he made sure that the bulk of it was safe, and helped us with buying a house, a car, all that kind of thing. Nothing too showy—if we spent it all frivolously, we’d burn through it in a few years, but with smart investments, treating it it sensibly, only using it when we had to…that four million, Dad said, was enough to live off for the rest of our lives.

Two months after everything finished, I had a housewarming. Petra and I got pretty drunk, and ended up sleeping together. The next morning, neither of us spoke about it, but we silently agreed that _that_ was the last time—for real.

And then, two weeks later, at Petra’s housewarming, we did it again.

It was just so…easy. We’d spent so much time together, we knew each other’s bodies so well. And we really did love each other—that wasn’t something the sick old man had added, he just…accentuated it, I guess. Petra is probably the person I’m closest to in the whole world. I love her in a way that I’ll never love anyone else, and I know she feels the same way about me.

Don’t get me wrong, I know how fucking wrong it was. So did she. But after few drinks, or a particularly bad day, or even just when there was nothing else to do but sit in our big empty houses and slowly go mad…we’d turn to each other for comfort. And it _was_ comforting. There was love, there was a connection, there was a history…and there was just good old-fashioned chemistry between us.

No one ever caught us, or even came close. Maybe we were lucky, maybe we just had a gift for sneaking around. Having our own places probably helped…I’d go around to Petra’s to help her move some furniture, I’d stand too close or something like that, and we’d just lean in and start making out like a pair of horny teens.

I tried to get her out of my system, truly I did. I even went around to Lord DeGrave’s and took him up on his offer. When I got there, there was a girl in cat ears waiting to see him…I never did find out what that was all about.

Bethany was incredible, don’t get me wrong. Those boobs…those legs…that submissive side that she just couldn’t hold back. But it wasn’t the same.

I considered taking a trip around the world, but it wouldn’t erase the memories. I even considered becoming an alcoholic, but every time we had a drink, it’d happen again.

I spent weeks, months…hating myself, tempted to go to the casino and burn through my whole fortune in a night. It was taking over my life…killing me…and I’d have bet my life that Petra felt the same way.

Finally, I knew what I had to do.

* * *

“The Cookes are here to see you, sir.”

“Who?”

“The Cookes, sir. Petra and Craig.”

“Ah, yes! Back for more, is he? Well, I don’t need you for the rest of the day. Go on, Bethany, you’ve earned yourself a piece of young meat.”

“His sister is here too.”

“So? You’re bi, aren’t you?”

“Yes, sir, but…they’re here to see _you_.”

“Hmmph. Well…send them in. And offer them tea. They’ll say no, but I want to see the look on their faces when they do…”

“This way, sir, madam. Tea?”

“ _No._ ”

“Of course, madam.”

“No thanks, Bethany.”

“A pleasure to see you again too, sir.”

“Okay, enough small talk. What is it that you two are after? I do hope you’re not going to be troublesome. That would be…unfortunate.”

“It’s not that, Lord De—…”

“We’ve shared a woman, lad…call me Mason!”

“Fine. Mason, Petra doesn’t know why we’re here.”

“What was that? Speak up, girl?”

“I _said_ that I didn’t want to come.”

“It was my idea, sir. We…I…I want you to turn us back.”

“Hmm?”

“To how we were before…your package.”

“What?”

“ _What_?”

“Petra, just…trust me.”

“Craig, I have no interest in going back.”

“Seriously, sis…I know what I’m doing.”

“I…fine.”

“So…the two of you “want to go back”? Now I’m old, my hearing’s going, my mind isn’t what it used to be. Tell me…what _exactly_ do you mean by that?”

“I…we…we want to go back to before we realized we were under a spell, or whatever it was.”

“ _No_ we _don’t_.”

“Yes, Petra, we do. I can see it on your face every day…it’s killing you. Just like it’s killing me. We know what we’ve done, there’s no going back. But I don’t want to live with it, every day…do you? I don’t want to wake up each morning knowing that I’m a sister-fucker…and worst of all, knowing that I’ll do it again.”

“Ah ha, so the pair of you _did_ …—“

“Just shut up, Mason. Petra, listen—you know I’m right. It eats me up inside, every day. I can’t sleep, I can’t eat…and honestly, I’m even struggling to jerk off without visions of you popping into my head. There’s something here, something…weird, and disgusting, and sexy. Something strangely wonderful. And I don’t like it, but I _want_ to. I want to like it. And Mason—Lord DeGraves…he has the power to make the bad half of it go away. He has the power to make it just be a good, beautiful, sexy, _fun_ thing. I love you. That’s all I want. I want to love you without any of the guilt, without any of the self-loathing or the hate or the…I just want the good stuff.

“…and I know you do too.”

“…”

“…you know I’m right, Petra.”

“…fine.”

“What’s that, girlie? My hearing’s not—…”

“ _Fine_.”

“Ha! So it’s a bit of guilt-free sibling loving you’re wanting, is it? Well, sure, I can do that for you…but it won’t come cheap. How does one million each sound?”

“Mason, we—…”

“That’s Lord DeGraves to you, missy. Unless you want me to call Bethany back in here—I’m sure she’d be willing.”

“Lord DeGraves, please…we’ve earned this. You know we have.”

“…”

“…”

“…fine! _Fine._ But don’t let word of this get out, do you hear me? I don’t want people thinking I’ve gone soft in my old age.”

“Believe me, your Lordship, I don’t think there’s a risk of anyone thinking that about you. Ever.”

* * *

The couple looked out over their new house. Halfway across the world, in a country where they knew absolutely no one.

It was amazing what money could buy.

A few dollars in the right hands, and no one knew where they’d gone. And when they had arrived, their last names being the same had been interpreted as the sign of a married couple—an assumption that was reinforced by the constant affection between the two. The hardest part had been convincing their parents not to look for them, but again…they’d been strangely understanding, and avoided asking any of the wrong questions.

As soon as Petra stepped inside the house, she’d slipped her top off, and when she’d greeted Craig with the sign of two brown, pert nipples, he’d laughed…and taken no time at all to lean down and pop them in his mouth.

“Oh, husband…” Petra moaned as he tasted her for the first time in the new country.

“Oh, sis…” he replied, as he moved from one nipple to the other.

Her breasts were noticeably bigger, he decided, as he undid her skirt and watched it fall to the floor. She reached between them, and unbuckled his belt, the same thrill of anticipation hitting her as it always did. His cock hit the brisk air, and she smiled, and got down on her knees.

“Wouldn’t want you getting cold,” she said with a smile, before slipping her mouth over his hard member, and warming it up.

Fifteen minutes later, Craig was cumming inside his sister for the second time as he spanked her pert butt. He’d decided to fill up her ass this time—in the coming months, it was possible that they wouldn’t be able to do all the positions that they were accustomed to, and he felt that anal would almost certainly be the first to go.

She sighed, and lay her head against him.

“Do you know what my favorite thing about this place is?”

“Well,” Craig said after a pause. “We’ve only just got here, so I’m going to guess…what we just did?”

“No,” she said with a laugh. “No, it’s the fact that I don’t have to wear clothes. I’m never going to have to wear clothes inside my own house again…”

“Not _never_ ,” Craig responded jovially. “I mean…”

His hand drifted down to her stomach, and she covered it with her own.

“True,” she said, after a pause. “But…well, not for years. And maybe we’ll have one of those naked houses.”

“Maybe,” Craig said, and held her for a few minutes before getting up.

“Where are you going?” she pouted, wondering why he hadn’t picked up her leash and taken her with him.

“I promised Mason I’d send him our address as soon as we got here.”

“Ew,” she shuddered. “That guy gives me the creeps. Why are we even still in contact with him?”

“Well, he did sort of get us together…”

“I suppose,” Petra said, with a roll of her eyes. “In a way…but why does he need our address?”

“Don’t you remember that conversation before we left?”

Petra thought hard for a minute, before shaking her head.

“No?”

“I really don’t.”

“He said that if we sent him our address, he’d make sure that Trish—that’s the girl who runs that bakery you like—would send us a dozen cupcakes every month. I’m addicted to those things, and don’t lie—I know you like them too. It’s been almost two weeks since I had any, and already I’m jonesing…”

“Fine,” Petra said, her laughter following him down the hall. “But hurry back! I want to christen every room in the house…tonight, if possible!”

* * *

Lord Mason DeGraves leered at the blonde eighteen-year old girl sitting in front of him.

“And…you’re sure you’re not a cheerleader?”

“Hey! Don’t you speak to her like that!”

“Dad!”

The girl hit her father on the shoulder, and he rolled his eyes and sat back in the big chair, sipping at his tea, trying to pretend that there was nothing strange about the fact that his daughter was sitting on his lap and chatting to a billionaire about her hobbies.

“Sorry about that, your Lordship. It took me a while to convince him to come…and then I told him how much you were offering. One and a half million, wasn’t it?”

“That’s right,” the old man said with a wicked grin. “One and a half million, in cash. You’ll receive it in cash at the end of the month, provided you follow my every instruction. I can get you security to follow you to the bank, if that’s what you want to do. It’s your money—I just want to make sure you don’t lose any of it!”

“Of _course_ not,” the girl who was apparently _not_ a cheerleader said, flashing her brightest smile at the old man.

“And all you have to do for it is sit down together once an evening…and watch one hour of porn.”

“ _Dad_ ,” the girl said, as her father began to stand up in anger.

Lord DeGraves sat back to watch them with a smile. This, he knew, was going to be a fun one.
