My sister likes taking risks

My sister likes taking risks, Personally, I blame my parents.

They were the ones who insisted that they needed privacy and banished us down to the finished basement with its old, smelly carpeting and busted up furniture. It was our parents who decided that cable was a huge ripoff and Netflix was a scam, leaving us to explore the depths and dangers of broadcast television. And It was our parents who said — even though I was a senior in high school and Emily was a freshman in college — that we weren’t allowed to go out unsupervised.

It’s like they wanted us to get into trouble.

Emily and I were sitting on the couch in the basement, TV on in the background, talking about stuff that we probably shouldn’t have been. Despite being older than me by a year, my big sister Emily was tiny next to me. She had light brown hair down to her shoulders. A perky little nose that turned up just slightly at the end. A wicked, sensuous smile.

Emily was telling me about college — she went to state school but Mom and Dad made her live at home. That whole trust thing again. She talked about classes and friends and, of course, boys. I asked her if she was seeing anyone and she said no.

“How can I with Mom and Dad’s rules?” Emily asked, “What about you, Ryan? Breaking any high school girls’ hearts?”

“Obviously not,” I said, “I’m living with the same bullshit you are.”

“Seriously,” Emily said, “All I’ve got in my life is porn, plus Rosy Palms and her five little sisters.”

If I’d been drinking, I’d have done a spit take. My big sister said what?

“Oh come on,” Emily said, “You can’t tell me you don’t do it, too. Plus you’re a boy. I bet if you don’t jerk it at least twice a day your head just pops off.”

I laughed and admitted that I did it at least that frequently.

“See?” Emily said.

“And you?” I asked.

My big sister blushed. “I do it enough,” Emily said, “OK, probably a bit more than enough.”

I had to laugh at that and Emily did too. It was a nervous laugh. Like edging water from a hose, it came out too loud and strong because of all the pressure building behind it.

“Look at us two losers,” I said, “Sitting in the basement watching old game shows and talking about masturbating.”

“You’re not a loser, Ryan,” Emily said. She reached over and touched my arm. In that moment it felt as intimate as if she’d grabbed my dick. “Your dirty blonde hair. Big green eyes. You have those sexy legs from soccer. You make me laugh all the time. I mean, any girl would be lucky to have you.”

“If I could ever take one on a date, let alone bring her home,” I said.

“You’ll be fine,” Emily said, “I’m the one who’s going to end up as an old maid.”

“Oh Emily,” I said, “Are you kidding? You’re fucking gorgeous. If you think my green eyes are so great, well, you’ve got the same ones. Your lips are so pink and kissable. And your body. I mean, wow.”

“No tits,” she said.

“They’re perfect for your build,” I said, “You’ve got great legs and your butt is just… Not to mention how smart you are. The way you always outwork everyone else. Any guy would be lucky to have you.”

“If I could ever take one on a date,” Emily said, “Let alone bring him home.”

“Exactly.”

We sighed in unison. “Do I really look that good?” Emily asked, “Not to my brother. But if you put your, like, guy goggles on.”

I mimed putting on a pair of glasses and then slowly studied my sister from head to toe. “Yup, pretty hot. From what I can see, anyway.”

“You’re saying if you saw me naked, you might change your mind?” Emily asked.

“It’s just that… Well, your clothes aren’t exactly revealing.” Emily was wearing a pair of loose-fitting sweatpants and a beat up, white t-shirt. It looked comfortable, but she wasn’t asking me about comfort.

Emily smiled at me. I knew that smile. It was the one that said she was about to do something dangerous. My sister had always been a bit of a risk taker. One of the reasons she didn’t have a car, that Mom actually dropped her off at school every morning, was that my parents were terrified whenever she was behind the wheel.

“So if I take off my shirt, you might give me a more honest appraisal?” Emily asked. She didn’t even wait for my response, just ripped her t-shirt over her head. Now my big sister was sitting in front of me in only a thin, white bra. Without the shirt, I saw that she’d sold her breasts short. They were actually pretty big, standing pertly on her chest. It was all those loose clothes she wore — they made her look less endowed than she was.

“Your turn,” Emily said.

Reflexively, I looked behind me. Though I can’t imagine what I was worried about. We were a full flight of stairs under the rest of the house. There was a thick metal fire door at the top that my father insisted had to stay closed at all times when we were downstairs. In fact, my parents never even came down there — they’d always just knock and yell if they needed something.

The house was old, too, with thick walls and floors that seemed to swallow sound. Emily and I could have started a heavy metal band down there and my parents wouldn’t know until we invited them to our first concert.

Sure that the coast was clear, I stripped off my shirt and tossed it to the side. Emily’s eyes went wide.

“Holy fuck, Ryan!” she said, and started tracing the muscles in arms, my chest, “When did you get these?”

“I don’t know,” I said. Honestly it wasn’t something I really paid attention to. I was trying for a soccer scholarship and so I’d been working out at least twice a day, once with the team and once on my own. “I guess getting ready for the season, I just…”

“You wear such loose clothing,” Emily said, “I never really noticed.”

Her hand hadn’t left my bare skin. I couldn’t help myself — I reached out and touched the top of her boob.

“Holy fuck, Emily,” I said, “When the fuck did you get these?”

My sister gave me a dirty look, but she didn’t push me away. “I was 12, remember. You were there.”

“Yeah, but, I mean… You were complaining about your boobs before but these are really awesome,” I said, still touching the tops of her tits. “You’ve got an incredible body, Sis.”

And she did. I knew my sister was cute, I’d already told her that. But this… Her stomach was washboard flat. Her skin pale. Without really thinking about it, I dropped my hands to her sweatpants and pulled those down.

Emily didn’t do anything to stop me. She was wearing little purple panties. I could see bits of her brown pubic hair poking out. She was short, but her legs were lovely, with the shape and tone of a taller woman.

Emily looked down as if scandalized, then reached over and ripped down my shorts. She didn’t even let me keep my underwear. She just took it all in one swift pull. My penis popped up, tall and pulsing. I was hard — of course I was hard after everything we’d been saying and showing.

“Wow,” Emily said, “Wow wow wow.”

“I’m sorry,” I said, “I didn’t know you were going to…”

“It’s so… I mean, I’ve seen them online and stuff but…” Emily was just mumbling to herself. Rambling on and on.

The couch felt weird and scratchy on my bare bottom. The TV was showing ads for carpet cleaner. I suppose I should have been uncomfortable or embarrassed. But instead it felt really natural. Just sitting there naked in front of my sister.

I guess I thought she should have the same experience. I reached over and grabbed at Emily’s panties. She lifted her perky butt and let me slide them down to the floor.

Her pussy, like the rest of her, was small and well shaped. I’d never seen one live before, but it looked much more perfect to me than anything I’d seen online. Cuter and more feminine. I was desperate to touch it, but I made myself stay back.

Emily just smiled, then reached behind herself and undid her bra. Her breasts were gorgeous, little pink nipples all crinkled and hard. We were both now completely naked. Both breathing heavy like we’d gone for a run. Emily’s whole face and the top of her chest was pink. I felt like I probably looked the same way.

We were siblings, after all.

“Now imagine you’re not my brother,” Emily said, “You’re just some guy. What do you think?”

“I think you’re amazing, Emily. I’m not exaggerating. I think you’re the most beautiful thing I’ve ever seen in my life. And you? What would you think if you weren’t my sister? Just some girl.”

“I want you really bad,” she said. “Sister or no.” Then she leaned forward and kissed me, hard. Her tongue probing my mouth. Hands drifting over my chest. I leaned back, a little scared. She was so incredible, but…

“But you are my sister,” I said. Gasped between kisses. Emily sat back and made a pouty face.

“I want you, too,” I said, “I really do. But I mean… I just think we can go too far. You know?”

Emily nodded. “No, I definitely don’t want that. I just…”

“No, I know,” I said. We ran our eyes all over each other. Like hunting down every part we wanted to touch and lick and…

“Well what about what I said before?” Emily said, “About my friend and her little sisters? Couldn’t we just do that?”

“You mean, like, together?”

“Yeah,” Emily said, “I mean, I’m sure you think about… stuff when you do that. I do. And after today, I mean, I think I’m going to be thinking about my little brother a lot.”

I couldn’t argue with that.

“So why not just do it together?” Emily said, “No touching. Just, you know, together. It’s no different than if we went upstairs and closed our bedroom doors and did it. Which I’m telling you is what’s going to happen if we don’t right now.”

I certainly wasn’t going to argue with that. Emily took my silence to mean I was into it and started working herself with abandon. I’d heard that girls needed time to build, to touch and tease, and gradually work themselves into the mood.

Not my Emily. Before I’d even started stroking, she had two full fingers in her twat and was rubbing her clit so fast I could barely see it. We tested the soundproofing of the house that night, let me tell you. Emily screamed like she was getting stabbed when she came. A long loud “FFFFFFFFFUUUUUUUUUUUUCK!”

I wasn’t far behind — I grunted and my semen exploded upwards with a strength I’d never experienced. It splashed warm on my stomach. My legs. When I recovered I looked up and saw that I’d accidentally gotten some on my sister’s chest. Right on her boob — better than if I’d aimed it there.

She just laughed and scooped it up. Then she sucked my sperm off her fingers and I swear I almost came all over again.

“Not bad,” she said, “Kinda salty.”

We got dressed again and watched TV and eventually my parents called us for dinner. I knew it wasn’t over. But, as long as we weren’t touching, I figured we’d be fine.

*

We were fucking within a week.

Every day we’d break a new boundary. The next time we rubbed together — that same evening, right after dinner, if you can believe it — Emily insisted I cum all over her chest and face. Next she wanted to be the one to point my penis when it shot.

That broke the touching taboo. Soon she was stroking my dick while I worked her pussy. It took a couple of false starts — she gripped too hard, me not hard enough — but eventually we got really good at getting each other off. It reached the point where the few times I tried to do myself, I couldn’t even climax. My big sister had trained me to her touch.

After touching came tasting. Emily had sucked my sperm off her fingers (and her tits, and her hair) so of course I had to experience her own girl goo. It was kind of sweet and thick and I loved it so much I had to get some from the source.

So now we weren’t even bothering with hands. Just lips and tongues and even a bit of teeth. The first time my sister swallowed my load, I could have died right then and there.

And once your sister has your dick in her mouth while you’re licking her snatch, well, it’s pretty simple to spin around and jam your cock in her pussy. At least that’s what we discovered.

By that point Emily had figured out the way to get me to do things that I might not otherwise agree to. If she brought something up cold, like “I want you to fuck my titties.” I’d get nervous and say no. But if she started with something I’d already accepted and then stopped right before I blew my load she knew I’d say yes to almost anything.

My cock was in Emily’s mouth and her sex was in mine. I felt the pleasure building and then I heard a pop as she pulled her mouth off my dick.

“Spin around,” she told me and I did. My cock nestled between her legs. The root resting right at her most precious place.

Emily kissed me hard, clearly she didn’t care about tasting herself. Actually, she told me she thought it was really hot and would find ways to “accidentally” get some of her pussy juice in her mouth.

Then she looked up at me with her big green eyes and said, “Stick it in me.”

I froze. I mean, I really did. Like my whole body just stopped responding.

“Come on Ryan,” Emily said, “I’m on fucking fire and my pussy needs that hard cock so bad. Put it in. Come on. Give your big sister what she needs.”

“Condoms,” I managed to croak out.

“What? Noooo. I want you inside me not some thing wrapped in latex. I trust you. I know you won’t put your stuff in me.”

But I argued her out of it. It just wasn’t a good idea. We were both smart enough to know that even if I didn’t cum in her, I could get my sister pregnant. And that really was too far. Even Emily agreed with me on that.

Condoms were the only option. Our parents wouldn’t let us go on dates, they certainly weren’t going to let Emily start taking the pill. My big sister talked about trying a convoluted story about an irregular period, but we both knew such a deception could take months. Neither of us was going to last that long.

“We can go too far,” I said, “If we’re not careful. If Mom and Dad find out, if anyone did, this would be over in a second.”

Emily nodded. I knew she didn’t want that. But she stayed sulky. I got, quite possibly, the most mundane, indifferent blowjob a sister ever gave her brother. I did my best to get Emily off, as well, but after a while we just gave up and went to bed.

So it was that four days after my sister and I had agreed that ‘no touching’ was a safe boundary for both of us, I slipped out and bought a box of condoms on the way home from high school. That night we were in front of the TV — Family Feud was on. I remember, because of all the dinging in the background.

We got naked right away. I started kissing her, moving my mouth to her pussy, but she just pushed me away. I swear she almost stuffed my stick inside her before I could put the condom on. It wasn’t easy. I fumbled it a few times.

I moved my cock around for a bit, trying to find the right spot. Then Emily reached down and guided me in, herself. Just like that, without saying a word, my sister and I gave each other our virginities.

Saying ‘just like that’ makes it sound simple, which of course it wasn’t. First I had to break through her barrier, which made her scream bloody murder. If we hadn’t proved how thick the walls in the house were before, we did then.

All that stimulation of sliding back and forth in my sister’s tightest place was too much for me and I came. So while my sister was howling in pain, I was rolling in pleasure. I pulled out and the condom was covered in blood, filled with my semen.

That was the point where I knew, truly, that my sister loved me. That was the only way to explain why she was willing to fuck me again after all that. And boy, did she ever.

After we both cleaned up we tried it again. Then again. I penetrated my sister until I could last inside her more than minute. Then we worked at it again until she was — with a copious amount of clit rubbing — able to cum on my cock.

The next day I was back in CVS replenishing my condom supply. My original purchase of 15 hadn’t been nearly enough.

*

After that, my sister and I fucked like we were incapable of anything else. We would wake up early in the morning and sneak downstairs for a morning fuck. Then after school we’d race down and do each other as many times as we could until dinner. After eating we’d go back for an evening session.

I’m not superhuman but I was in high school and so my cock was able to keep up with a lot of it. When it wasn’t, my sister would just ride my face or let me finger her. Sometimes she would sit there and work herself while I watched. We fucked in ways that made rabbits worry we might be overdoing it.

And I say fucked, not made love or had sex or whatever because that’s what we were doing. Emily told me she loved me on that second day of fucking. I’d blasted my cum into the condom and then worked her till she shuddered. As we separated, Emily grabbed my arm.

“I love you, Ryan,” she said, “You know that right? Not like a sister. More than a sister. I love you love you.”

And I told her that I loved her, too, because of course I did. But if it was supposed to be some big moment or whatever, it wasn’t, and as soon as I was able to get another condom out of the foil we were rutting like degenerates on the basement floor. I think I got permanent rug burns from that stupid shag carpet.

We never did the whole slow, loving sex thing where I kissed her and she kissed me and we slowly brought each other to shared ecstasy. We just… fucked. Fucked like teenagers raised on video games and YouTube clips. Drove into each other until we each got what we needed and then, when the satisfaction drained away, we did it again.

*

I kept telling Emily we could go too far and she kept proving me wrong. We started a new tradition of finished off our day by sneaking into each other’s bedroom and fucking, one door down from our parents. One morning our Mom was running late and so we fucked in the backseat of her car before she came out to drive us to school.

The best was a weekend in April when my parents took a trip with friends to the Poconos and left us to our own devices. If they’d done that a few months before, I’m sure Emily and I would have been planning for weeks — going to parties, setting up dates — whatever we could to take advantage of our fleeting freedom.

Sex stories:   More than Just Mother and Son, He did mom's lez lover too! (True Story)

Instead, we spent the whole weekend in the house, fucking in every room including the garage and all three bathrooms. We even fucked on our parents’ bed. Twice.

I began to wonder if it wasn’t just the sex that got my sister off, but the risk of it. Not just fucking but fucking her brother and doing it in places and ways where we were bound to get caught eventually. And once something was done safely, she had to raise the stakes. Chase that high.

If my parents suspected anything, they never said. Frankly it served them right. It was all their fault, after all.

*

That big April fuckfest weekend turned out to be a turning point. It felt like this big moment, a beginning of something even greater. We’d even jokingly named the whole thing Emancipenis (or Emancipussy, depending on who was talking) Weekend because we felt like we had some freedom for the first time in our lives.

Emily had even made an Emancipenis Proclamation speech while riding my cock on the dining room table. There was much applause, I promise you.

I could only imagine where we would go from there and I guess Emily felt the same because now nothing seemed to live up to it. Having to hump quietly in our basement hideaway just didn’t have the same appeal after screaming orgasms echoing throughout the house.

We tried a public bench one afternoon, but chickened out at the last minute. There was risky and then there was stupid. That’s what I told Emily, anyway. We really could go too far.

Life started to intrude, as well. I was a month from graduation and I still hadn’t heard about my scholarship. It made me stressed and mopey which just sucked away my energy for sex. Emily wasn’t around often enough for it to matter, anyway. Finals hit hard and she basically disappeared from the basement. She was either studying in her room or at the college library and I almost never saw her.

I knew it was OK, that it was just a thing we had to go through, but one night I got scared. I knocked on her door and she let me in. Her room was covered in dirty clothes and discarded paper plates — the bed, the floor, everywhere.

Emily was wearing a big maroon sweatshirt with grey sweatpants. She had her glasses on, which I almost never saw. She barely looked up from her book when I walked in. We talked for a second, just about boring stuff, and then Emily asked if I wanted anything because otherwise she was busy. With the clock ticking I managed to just spit it out.

“Emily I know you’re super busy and if that’s all it is that’s fine I’m just worried. Are we breaking up?”

“What?” my sister said, looking at me for the first time, “No. Don’t be ridiculous.”

So I let her get back to studying. But I swore I heard her crying as I closed the door behind me.

*

It was the middle of May. A drippy, dreary day that seemed to demand everyone stay inside. My Mom was upstairs making dinner and my Dad was in the dining room doing a work thing.

Finals were over. Emily was still sweating out test scores, but her time was, once again, her own. I’d gotten the scholarship and I’d be starting at Messiah in the fall. We would still be close enough to see each other — it was only a three hour drive away — but still.

For what felt like the first time in forever, my sister had joined me down in what I’d come to think of as our ‘playroom.’ The basement was lousy when it rained — it felt damp and stank of mildew, so we sat fully clothed on the couch, wrapped in a heavy knit blanket.

We hadn’t fucked in days — really hadn’t been regular for weeks. By this point, my balls had been trained to produce multiple loads of cum for my sister every day. Now it was all just building up in there. Worse, my cock had grown accustomed to Emily’s pussy (and her mouth, and her hands, and her tits). Jerking off felt strangely empty and unsatisfying.

All this meant that my testicles were incredibly tender. I had to sit in a certain way just to keep from hurting myself. Emily seemed fidgety, as well. She kept shifting position and making these little frustrated grunts. But neither of us suggested doing anything. Not even a wink or a playful grope. And so we just stared mutely at the TV as I flipped the channels.

As I said, my parents wouldn’t pay for cable so we just got broadcast down there. We had all the basic stuff plus these strange, sub-channels that would play, say, three hour marathons of Night Court or all the Robert DeNiro movies that weren’tgood.

Every now and again though we’d trip over something classic. That afternoon in mid-May we hit the jackpot: Rebel Without a Cause. Emily had never seen it so we watched. The movie had that saturated look from old color movies and the red of James Dean’s jacket seem like the warmest thing in the world.

We got to the ‘chickie’ scene. James Dean gets in a knife fight with Buzz, but that’s not enough. They agree to race each other, heading toward a cliff. Whoever jumps out first is ‘chickie.’ They line up all the other cars and flip on the lights. Each guy gets some dirt on his hands. And then they peel off toward death and destiny.

Emily had been sort of in and out of the movie to this point, but when we got to this scene she leaned forward. She just stared, enraptured, as the two cars took off. The cliff got closer. Dean’s rival, Buzz, got caught on the door and couldn’t escape in time. While Dean rolled to safety, Buzz’s car went over the side.

“Holy fuck,” Emily said, “I want to do that.”

“You want to play chickie?” I asked, a little nervous about what my sister might be planning.

“Yeah,” Emily said, “That would be awesome.”

“Seems like a good way to get killed,” I said.

“Not like with a car. Just something like that. Where you know that everything is at stake — your family, your friends, your life — but you race towards it anyway. Knowing in your heart that you’ll have to stop at some point. But driving like you never will. Finding that point where your courage stops and then going just past. It’s like… running with the bulls. Or jumping out of a plane.”

“You’re not exactly selling me on this idea.”

“Come on, Ryan. Don’t you feel it? We’re trapped in this antiseptic life where even if we wanted things to go wrong our parents wouldn’t allow it. Don’t you just want to test yourself? See where your limits are? See if you can break through them?”

“I understand,” I said, “I think. But it also seems kind of scary.”

“That’s the point,” Emily said, “To be frightened. To live with real consequences. For once.”

“And if you go over the cliff?”

“You don’t,” Emily said firmly, “You know when to stop. But in that moment. Wow. That has to be amazing.”

I was sure Buzz planned on getting out of the car before he went over the cliff, too. But I didn’t say anything. I just let my sister enjoy her fantasy.

Then she grabbed my hand, maybe a bit too hard. “I have an idea,” she said. She tossed off the blanket and stood up. In seconds she went from jeans and a t-shirt to completely naked. Without thinking I did the same. It felt like ages since I’d seen my big sister this way and my body hurt with how much it wanted her.

“I’ll get a condom,” I said, but Emily grabbed my wrist again and shook her head. She pointed for me to lay down on the shag carpet. My penis pointed up proudly, as hard and straight as I’d ever seen it.

Emily stood over me, legs apart. She looked down and smiled. Slowly she lowered herself down. Leaned forward and kissed me on the lips. My penis bounced against her bare, unprotected pussy. God, she looked so beautiful.

“Just like in the movie,” Emily said, “We’re both going to do something risky. We’re going to race toward that precipice. And we’ll see who gives up first. Got it?”

Then she reached back, took my bare cock in hand, and aimed it right at her dripping puss.

Oh fuck. “Emily!” I shouted, “If you put me in without a condom I could…”

“Exactly,” Emily said, “I’m going to stick your dick in my pussy and we’re both just going to sit there. Neither of us moves. We just wait until one of us loses the nerve and pulls out.”

“Fuck. Emily. This… This really is too far now. I mean if I get you pregnant, Emmy? Our whole lives could be ruined.”

“It’s not too far,” Emily said, “Not yet.”

“OK, wait,” I said, “We haven’t done it in a while. My balls are… They feel really full. And my cock. I mean, I doubt I’ll last a minute. Maybe we just have a quick fuck first, get out some of the tension. Then try.”

“No,” Emily said, “That’s the game. There’s the risk. That’s what makes it work. Because there is all that danger. Our whole lives in our hands. Besides, you’ll stop before it’s too late, right?”

I nodded.

“Well so will I.” Emily smiled and picked up my cock again.She placed it at her pussy and then started to slide back. For the first time, my bare head, my naked shaft, rubbed against Emily’s labia. Her vagina. And then I was completely sheathed in my sister. Without anything between us.

Sex stories:   My hot sister renu

“Holy FUCK! That feels fantastic!” Emily said.

“Uh huh.” It was the closest I could come to coherence. I thought we’d been fucking all this time. That I’d known what sex was. It was nothing. Being inside Emily without a condom was like the difference between a scrimmage and a championship final. They were barely the same sport.

“How the hell did I ever let you talk me out of THIS?” Emily asked.

“Pregnant,” I croaked.

“Oh right,” Emily said, “Good point. Anyway, this is the game. Whoever can stay the longest.”

I had to admit, in that moment it was exhilarating. And the same things that made it so exciting — my naked sister, my condomless penis, her unprotected pussy — also made it terrifying.

Emily rocked back onto her knees. She looked down at our juncture and smiled. “I always thought that looked so hot. You buried inside me.”

I could see now that she was teasing me. Using dirty talk to get me to go first. Only she didn’t need to tease — I was ready to burst already. But I held on. I knew I had to. If we stopped now Emily would just make me go all over again. I had to let her have her fantasy, just like she said: get as close to the edge without going over.

I shifted a little and Emily warned me that I wasn’t allowed to thrust. Only to lie back. As if that somehow made things safer. Like her warm, tight pussy wasn’t squeezing, pulsing, pulling at my cock for its precious seed.

Instead I reached up and grabbed her breasts. Pinched her nipples. I felt her pussy clench as I did it.

“God, I love these,” I said.

“I always thought they were too small.”

“They’re perfect. You’re perfect.”

Emily reached back and cradled my balls. Two could play this game apparently. “These are really full,” she said, “I don’t know if I’ve ever felt them when they’re like this.”

“Be careful,” I said, “They’re really tender.”

“Is all that build up just from me?” Emily asked, “I mean, you were unloading at least five times a day and then… Nothing. There has to be, like… God, at least 25, 30 regular cums in there.”

I groaned.

“You might give me quintuplets, all that sperm. Fuck. You’d better not cum in me, Ryan.”

“I won’t,” I said.

“I mean, just imagine, you think you’ve got it under control, then suddenly you slip and WHOOPS! There’s my baby brother’s baby inside of me.”

“You’re cruel,” I said. Emily just winked. I decided to try giving her a little scare. I flexed my penis in her pussy, almost like I might be cumming. She gasped, her face went white, and she even started to lift off a little. But then she laughed.

“Ohhhh, you almost had me there, big guy.”

“Worth a shot,” I said.

“You’ll be the first to give,” Emily said, “I just know you will. And then you’ll know that I’m the big sister.”

She bared down on my cock with her cunt, then laughed again. I groaned. I was getting close now. My need to explode slowly shifting from urge to reality.

“I’m like, really fertile now, too,” Emily said, “Like, I could probably get pregnant just from standing near some sperm today. My little egg is in my womb just waaaaaaaaiiiiting for some big bad Ryan spermies to come inside.”

I rolled my head back. All this talk was driving me crazy. I didn’t want to make my sister pregnant but my body did — my instinctive drive to reproduce didn’t care about college or disappointing my parents or any of that. It just wanted to make more mes and my big sister was telling it exactly what it wanted to hear.

I started to pant from all the pressure. The little spark of orgasm that started in the base of my penis slowly spread upwards.

“Getting… close…” I said.

“OOOO, yeah. I can feel that,” Emily said, “Your cock is like… swelling up inside me. Fuck. And I haven’t even touched my naughty little clitty. I’m telling you, Ry, I’m never going back to condoms. We’re going to have to find another way. This… this is just too good.”

She shifted her weight again, moved up more on her feet. Ready to spring off at the last second. She could see the cliff coming now and my crazy sister just slammed on the accelerator.

“My little brother’s going to give me his baby,” she started to chant, “My little brother’s going to give me his baby.”

“No,” I said, teeth grinding, “Can’t… Won’t…”

“Ready to give up then, little Ryan? Admit that your big sister is the best?”

Damn her. “N…no. Not yet.” I still had time, I could feel it. Maybe if we were actually humping I would go, but just sitting here, I could maintain control.

Emily relaxed a little. She looked down at where we were joined again. She seemed to be thinking. Then she bit her lip and her eyes went wide and wet.

“I missed this,” she said, “I really did. I got so used to having you in me. Maybe I forgot how much I need that cock in my pussy.”

“I missed you, too,” I said.

“I know we didn’t… Maybe I didn’t say it enough. But you know that I love you, Ryan. I mean it. Please. Please tell me you still love me.”

“Oh God, Emily. Of course I love you. I love you more than anything in the world.”

And then Emily’s pussy squeezed my cock as hard and tight as I’d ever felt it. Not just a grip but a rolling wave that went from my root, up my shaft, then squeezed my head. Her eyes popped open and so did mine.

It came out of nowhere. That little spark went straight to a raging conflagration, skipping every step in between. I raced to shove her back, to get my cock out of her pussy before…

“I win!” Emily threw her arms up in triumph.

I came inside my sister. Not a little spurt but a massive blast of joyous sperm that shot straight into her. A fire hydrant of fertility just opened up — not a stream or a spurt — but an explosion of force that filled her pussy in one shot.

“OH F…!” Emily started to lift off, but then my cum hit her cervix and she stopped. Her eyes rolled back in her head and she fell forward. My cock still buried inside her. My second blast was more voluminous than the first. My dick kept going back to the well, expecting to find it empty, but instead there was still more than it could carry and it raced to dump the contents in Emily’s snatch before rushing back for more.

I wrapped my arms around my sister, thinking I could pull her off my cock, but she held me so tight. Her body convulsing. And then a noise came out of my sister that I’d never heard before and would never forget.

It was a deep, primal sound. Something ancient from her animal brain. It started almost like a whisper and then immediately ratcheted into a deafening shout.

“hhhhhhrrrrrrrrRRRRRRAAAA AAAAAAAHHHHHHHHHHHH! FUCK! Oh FFFFFFFFFUCK! You’re cumming inside MEEEEEEEEEeeeeeeeeee!”

Another blast. Another. Filling my sister’s fertile twat over and over again. Ripping right into her womb. Our orgasms simply swallowed us up. I held onto my shaking sister as we both came and came like we would never stop.

“I LOVE my brother’s cock!” Emily howled, “I LOVE my brother’s CUM!”

Impossibly I felt my balls finally start to empty. My cock was still firing, but now it felt like smaller bits. Less and less. Emily’s orgasms subsided with mine. Oh God. There was no way that. I mean. She was more than pregnant… Oh God.

She stood up, both of us sticky with sweat. As Emily got to her feet, a rivulet of her brother’s sperm streamed out of her pussy and splashed onto my leg. She reached her hand down to cup under her sex. And then she started to laugh. A kind of low, thing, that sounded almost the same as a sob. I leapt up and wrapped myself around my big sister.

“I love my brother,” she said. Whispered it into my ear. “I love my little brother so much.”

And I told her I loved her too.

My parents heard us. Of course they did. My ears still echo from Emily’s orgasmic cries. Later, after she and I were able to joke about it, I named it her ‘pregnancy shriek.’ Her announcement to the world that she had conceived. I joked that she could join the X-Men, but of course that would require someone to knock her up every time they fought a bad guy.

When they heard Emily, Mom and Dad raced downstairs. We were still stumbling around like zombies. Covered in sperm and girl cum. There was no point in lying about it. This is meant to be a happy story in the end. So I’ll just say that things got ugly.

The good news is that this finally got us out of the house. Pretty much forever, actually. We got our own place. I turned down the scholarship and followed Emily to school. Got a job to help pay for things while she worked on her degree.

We stopped fucking after that fateful day. Instead we started making love. I’ve been lucky enough to hear Emily’s amazing pregnancy shriek three times so far. I’ve don’t think I’ll ever get tired of hearing it.

You really can go too far. I know we did. And it was the best decision we ever made.
