My sister and I share a bed [M/F] [Incest]

“No way am I sharing a bed with him!” My sister exclaimed. My mum sighed dramatically.

We were halfway through our family holiday, in some small town in the West of Ireland. The dreary weather outside was typical for the area, and so we were all huddled inside the small hotel lobby, a little damper than we’d like to be.

“It’s cheaper this way,” my mum explained wearily. “Really Elise, you used to take baths together. A night in a king bed is survivable.”

“When I was six!” Elise countered. “I’m nineteen now.”

“Old enough to deal with it,” my mum said with certain finality. I stood to the side, not speaking. I was unbothered by the situation. After a long day’s travelling, all I wanted was a good night’s sleep.

Elise huffed, blowing wet blonde hair from her face, and crossed her slender arms over the gentle swell of her chest. She was a bit underdressed for the weather, in a graphic tee and denim shorts that treaded a line between shorts and underwear. Goosebumps covered her forearms.

“Fine,” she said, probably too wet and cold to argue further.

We tracked a trail of wet suitcase wheels into the elevator and along the cheap carpeted hallway to our rooms. Mum stopped outside one door and handed us our keys. The hotel hadn’t upgraded to keycards yet, and still used old fashioned house keys.

“This is your room,” Mum said. “My room is that one just down the hall.” She indicated to one several doors down. “We have an early start tomorrow so don’t go watching TV until late.”

“Yes Mum,” we both said.

Satisfied, Mum dragged her hard-shell suitcase down the hall. Elise unlocked the door and strode inside, flinging her bag onto the nearest side of the bed. She ran her fingers up through the voluminous length of her hair.

“I’m going to take a shower first,” she declared. “Go read one of your books or something.”

I wordlessly took up the other side of the bed, plopping my bag down by the night stand. She rolled her eyes.

“Eighteen years and you still haven’t learned how to talk.”

I rolled my eyes back and we exchanged a smirk, the sibling banter going down well-worn avenues.

She went into the bathroom and the door locked with a faint click. Soon, the sound of running water started, tinkling onto a plastic floor. I focused my attention on my book.

After a couple of minutes the water turned off and my sister’s voice floated through the thin wall.

“Jack, could you get me my towel?”

I slotted in my bookmark and set the book aside.

“Where is it?” I asked, swinging my legs off the bed.

“In the bathroom,” she said. The door unlocked with another faint click. I went in. The shower was to my right and I kept my head politely turned left. The bathroom was a long, narrow room, and about three strides away from the shower, on the far side of the room, the complementary towels were hanging on a small rail.

“Sorry,” the disembodied voice of my sister said to my back. “I didn’t want to get the floor wet walking over there.”

I went and grabbed the towel and turned around to face Elise.

I expected to see her naked, so that wasn’t a surprise, but my body’s reaction was. My sister had her own bathroom in her bedroom at home, so I hadn’t interacted with her naked since we were kids. My eyes alighted on her unguarded chest, two modest but shapely breasts tipped with delicate pink areolas. Her skin was covered in goosebumps and beads of water, the cold air starting to seep in. My eyes traced a route down past her flat, toned stomach – she was on the swim team – to her crotch. I saw her trimmed bush and, beyond that, her vagina, and felt a jolt of electricity run right down my spine. It was like nothing I’d ever felt before, nothing like any of the pornos I’d watched. The sight of real, in person pussy and my body was dumping hormones. My cock stirred in my jeans and I felt heat rush to my face. I averted my eyes.

“Sorry,” Elise said again, oblivious to my arousal, taking the flush in my face for embarrassment. “It seemed easier this way.”

“No problem,” I said, my dick pressing so hard against my jean zipper it hurt. I handed her the towel and excused myself from the bathroom.

I tried to lie nonchalantly on the bed but my manhood was throbbing incessantly. I shifted it until it could unfurl to its full length, where it strained against the denim. My face was still hot and flushed and I was panting hot breaths despite lying down. All I could think about was her pussy nestled amongst her well-managed bush. The bathroom door swung open and Elise emerged, dressed again, toweling off her hair.

“Shower’s free,” she said.

I rolled off the bed and slunk into the bathroom, trying to obscure the bulge in my pants. I didn’t dare speak, afraid my voice would crack. I locked the door and shed my clothes. I looked at myself in the mirror. My tall frame was good for track and field and was free of any extraneous fat. My dick looked bigger than normal, its length curving up past my belly button. I touched it hesitantly. The head was burning hot, and twitched involuntarily at my touch. It was rock hard, more than I’d ever had it before. I had heard that flexing a muscle helped redirect blood flow away from an erection so I tried flex a bicep, which bulged pleasingly, but my penis didn’t shrink an inch. I tried tensing my thick, defined thighs, but even they couldn’t redirect resources away from my throbbing cock. It was going to take what I knew it needed – a release. I turned on the shower, hoping the sound of running water would obscure the noise.

I starting stroking my cock, trying desperately to think of anyone, anything else. A good porno I’d watched, or a pretty classmate, but all I could see, burned into my brain, was Elise’s tight body and pert breasts, nipples hard in the cold. My dick was a rod of hot iron in my hands, and pre-cum drenched the shaft removing the need for any outside lubrication. Initially, I was trying to be quiet, but I became lost in the moment, desperately stroking myself for a release. The wet sounds of masturbation filled the bathroom. I clenched back a groan as I squeezed my eyes shut and imagined my hands running down the flawless white skin of Elise’s belly, towards the heat of her womanhood –

I was wrenched from my fantasy by a knock at the door.

“Hey, you ok in there?” my sister’s worried voice asked through the door. “You’re taking a while.”

“Yeah,” I hurriedly said. “Just showering.”

“Alright,” Elise said, clearly not convinced. “Don’t take forever.”

I abandoned my attempt at masturbation and leapt into the shower. After briefly running soap over the important areas I got out and turned it off, hoping I hadn’t been in there an obscenely long time. My dick was still rock hard and throbbing, the head exposed and angry. I corralled it into my pajamas, a loose pair of boxers, and exited the bathroom. Elise popped off the bed, still in her clothes.

“Finally,” she said. “I need to brush my teeth.”

She went back into the bathroom, apparently not noticing my raging boner, now even more obvious in the loose fitting boxers. I got in bed, the duvet at least hiding the tent I was pitching. A short while later she emerged again. She pulled her pajamas out and changed in front of me. She kept her back facing me but through the reflection in the TV I was able to steal another glimpse of her tits, which sent another rush of endorphines through my veins and caused my cock to bounce beneath the sheets.

Her pajamas were a light cotton shirt and short shorts combo, showing off her tanned legs and threatening to reveal a nipple between the buttons. She slid into bed beside me.

“G’night,” she said.

“Good night,” I returned. She clicked off the light but we weren’t plunged into darkness, the anemic curtain letting the streetlights glow right through into the room. She settled into bed and drifted off fast while I struggled with my hormones, the body I wanted to ravage a foot away.

After a while, I was certain she’d be asleep.

“Elise,” I whispered. “Eli~ise.”

She didn’t stir. I shoved off the duvet, revealing my uncovered torso and her body down to just below her hips. I slid my meat from my boxers and felt it lying, still hot and twitching, against my stomach. Slowly, carefully, I started to stroke it, one hand tracking the full length of it while my other arm kept me propped up. I absorbed every inch of my sister: the tangle of her blond hair as it fell across her face; her delicate eyelashes that fluttered slightly from whatever dream she was in; her pale face, unblemished beyond a few light freckles; her soft pink lips, slightly parted for gentle, whistling breaths; her breasts, flattened by gravity and slid either side of her chest; the curve of her hips, quarter-turned towards me; the smooth, tanned legs descending into the sheets. It was all I could do to try keep the sound down as I rubbed my dick with the intensity of a man dying of thirst in a desert. My head spun as my eyes darted between each attention-stealing feature of hers: her cute button nose, her well-plucked eyebrows, the delicate nape of her neck, her sharp collarbones, peeking from the shirt. I felt the heat of an orgasm descending, sliding down my belly to my groin. My balls tightened up, ready to deliver a load of swimmers, and my cock bucked in my grip. I took one last shuddering breath and stared deeply into Elise’s open blue eyes.

Wait, what?

“Jack, what the hell?” she said, jerking up.

At the sound of my name I came, shooting hot ropes of cum up to my chest and down until a trickle dribbled onto my pubic hair. More ejaculate than I’d ever seen before laced me from pec to groin, the only thing hotter the heat in my cheeks.

“Elise,” I managed, it coming out in a moan.

“Jack, what were you thinking? I was literally right here!”

“I wasn’t,” I admitted. “I was just really horny. I’ve been on a bit of a dry spell with all this travelling, and I’m a teenager…”

“Well don’t just do it in the bed. Go to the bathroom if you really need to rub one out.”

“I tried to,” I said. “You interrupted me.”

“Oh,” she said, blushing. Surprised to even achieve that small victory in my compromised position, I was too speechless to respond. The semen on my stomach started to run down the valleys formed by my six pack towards my side.

“We have to clean you up,” she said. “I am not sleeping in cum-stained sheets.”

I went to rise but she stopped me.

“No,” she said. “You sit up and all that cum is running right onto the bed. I’ll get some tissues.”

She got up and tip-toed over to the tissue box by the TV, giving me a view of her firm, shapely ass. My penis, still erect, twitched again. She returned box in hand, and set it down beside me. She pulled out a fistful of tissues.

“I can do it,” I said.

“Just lay there,” she ordered. With the clump of tissues, she first wiped under my penis, smearing the cum entrapped in my pubic hair and chasing the rest up my stomach. My breath hitched. She traced along the lines of my six pack, soaking up any semen sitting in the undulating surface of my belly. I tore my eyes away from the ceiling to sneak a glance at Elise. Her face was flushed, her eyes glued to my chest and abs, and I could see her stiff nipples poking through her shirt. My boner, only slightly softened by the first ejaculation, resurrected with a vengeance. Elise gasped as my penis swelled and lifted up off my stomach. Her hand shifted up to the last string of cum nestled between my pecs, and when it did I took a chance. I lay my hand over hers and pulled myself upright. She was perched on the edge of the bed, her body leaning over mine, and now I was sitting up, looking down into her shocked eyes. Our chests almost touched and my cock scraped against the hanging fabric of her shirt, leaving a slimy snail mark. Her lips parted, perhaps to say something, but they lured me in and I lunged in for a kiss, pressing my lips against hers. For a moment the kiss was returned, her mouth moving against mine, her tongue giving a fleeting visitation, then she pulled away, gasping for air.

“We can’t,” she said. “We’re brother and sister.”

“I don’t care,” I said. “Look at my cock.”

She looked down at it. Gulped. It was a vessel swelling with uncontainable lust.

“You made it this way,” I said. “You. I can’t take anyone else.”

“I-,” she managed before I gently kissed her throat, the words dying in her mouth. She squirmed a little in my embrace, helpless against my muscular arms. Her hand ran down from my chest, over my washboard abs, down to the base of my penis. I planted a kiss on her shoulder and she gripped my cock. She started to stroke it, the shaft already drenched in cum and pre-cum. I returned to her lips, and this time she returned the kiss unsparingly, her tongue exploring over my front teeth. I could taste the toothpaste on her lips. I slid her shirt off at the shoulder and palmed one of her tits. She moaned, still kissing me, and I traced little circles around her erect nipple. She was stroking my cock more and more urgently, the tip pressed against her stomach. I moved my hand down from her breast to her pussy, sticking my hand down the front of her pants. She was hot and wet with desire. I ran one finger along the length of her pussy, from the clit to the vagina, enjoying the sticky rivulets of excitement that dripped free. I slotted one finger inside her, and she gasped between kisses. With my thumb I gently circled the clit while my finger scraped the roof of her pussy, searching for her g-spot. I felt something with the pad of my finger and she twitched. I extricated my penis from her grip and lowered myself to her vagina, pulling away her shorts. I attacked the same spot inside her pussy with a come hither motion while my tongue worked over her clit. She threw her body back, arching her back, and gripped my short cropped hair.

“Jack,” she moaned. I worked at her until she was a hot mess, quivering at my touch. Finally, I stood up and pulled her up until her pussy was at the edge of the bed. I placed my dick at the entrance of her pussy and slid it up between the lips teasingly before returning the head so it was kissing the entranceway. She placed a small, delicate hand against my hard chest. Her face was damp with sweat and strands of hair were stuck in her mouth.

“We can’t,” she said. “Seriously.”

“I’ll pull out,” I said.

“Don’t you have any condoms?”

I shook my head. “Do you?”

She covered her face in her arms and shook her head. “Just once, ok?” she said. “And make sure you pull out, we’re brother and sister. I can’t get pregnant.”

“I’d take responsibility if you did,” I said, truthfully. She twitched, her stomach undulating, and a flush spread up from her neck to her hidden face.

“Just once,” she said.

I pressed my shaft in, breaching the soaking wet pussy. Instantly I was enveloped by the hot, wet pussy, my legs almost giving out from the pleasure. Elise moaned, her back arching. Her pussy clamped down like a vice around me, pulling at me. I felt an orgasm rush up on me and went to pull out right away, but Elise wrapped her legs around me.

“Nooo,” she whined, “stay in a minute.”

I came, dumping buckets of hot cum directly into my sister’s pussy. It pumped into her, so much it was like I was pissing cum right into her womb. She must have felt the hot stream filling her up because she bucked and quivered, moaning in pleasure as she orgasmed from being creampied. Finally the flow stopped and her legs loosened, allowing me to pull out, panting from exertion. A pearl of cum rolled out of her dilating pussy, glistening, before it dripped down onto the bed.

“We got cum on the sheets after all,” I said dumbly. That must have knocked Elise out of her haze because she got up and hammered her fist ineffectually against my chest while she pulled the top sheet up to her chest in a weak attempt at modesty.

“You came inside!” she said.

“You leg-locked me,” I said.

“I didn’t expect you to cum as soon as you put it in!”

“I wouldn’t have, if your pussy hadn’t milked me dry when you orgasmed.”

Her mouth clapped shut as she blushed at me, stuck between anger and embarrassment.

“What’s done is done,” I said. “We’ll have to pick up some Plan B tomorrow.”

“With mum?” she said.

“I’ll think of an excuse to go in alone,” I said impatiently, “Let’s not worry about it now.”

I clambered back onto the bed and leaned in for a kiss. She pushed me back.

“Woah, what are you doing.”

I shrugged. “It’s not like you’re going to get more pregnant, sis.”

She scowled at me, but her eyes burned with hunger. She threw the sheet aside and spread her arms out into a welcoming embrace, her boobs sitting ready to be felt. I fell into her embrace.

We fucked relentlessly from there, all inhibitions falling away to lust. At first she was passive, being fucked in missionary or doggy-style, but she grew more aggressive. Soon she was riding me in reverse cowgirl, rocking her hips as she milked a fifth orgasm out of my aching cock. All sense of time fell away until I wrenched cock free from her grasping pussy and spilled a seventh orgasm onto her perfect toned stomach and noticed the first rays of sunlight falling across her beautiful breasts. I collapsed beside her, breathing hard, wrapped in sweaty sheets. I groaned. It was going to be a long day.
