A Quickie with My Sleeping Sister

My younger sister came home late from a party one night, showered and went to bed. It was hot and humid. I knew she wouldn't wear much to sleep in and I hoped she'd sleep on top of the sheet with no covers. I'd sneaked in many times before to try to see her tits or pussy, with limited success, but often just the hint of a nipple or the curve between her legs was enough to send me off to my own bed to jerk off.

We're the same age, 18, but not twins. Poor mum had us eleven months apart. Everybody told us my dad was an asshole and thankfully he died when I was three.

Janine had just turned 18 and this was only the third time mum had let her go to parties where booze was served. But Janine didn't drink much anyway, except I think this time she'd had a bit more than usual.

After waiting long enough to make sure she was asleep, I took my trusty mini-torch and sneaked in. As I'd hoped, she was on top of the covers, laying on her stomach as she often did. She wore a thin, light-coloured cotton nighty that came to her upper thighs. She snored lightly. Probably a bit drunk, I thought - she never snored, so I felt bolder.

Janine is five feet 9, with curly brown hair to her shoulders and fair skin. She's a little plump, so her raised butt was round and enticing. Sneaking quietly to the foot of her bed, I was delighted to see partly-open legs. Being a little thick, they were touching from mid-thigh up but my torch showed me she wore no underpants: I could see her bare bottom cheeks.

This was already a good night, but it was to get way better. Feeling sure that Janine was a little drunk, I lifted the hem of her nighty and there it was; a puffy little pussy, nestled between her fleshy thighs, and best of all it was entirely smooth, as if she'd never had pubic hair at all. My cock throbbed and twitched, but I did not jerk off. I had other ideas.

Incited by lust, then and there I resolved to try to get my dick in her. Obviously I couldn't just lay on top and go for it. I needed a plan. I blew cool air on her pussy and was rewarded with a snort and slight parting of the thigh as she bent a leg. More pussy, more lust. I squeezed my cock through my boxers, then just simply took them off. I had no need for them this night.

Kneeling between her knees, I froze as the bed creaked, but Janine didn't stir. I lowered myself on both arms until my cock brushed her outer lips. Her heat drew me further into lust, so I pushed gently. Straight away I was past her outer lips, in her warmth, but she was only moist and the friction stopped me. My virginal mind leaped to an idea. The stuff that coated my cock when I wanked was slippery. So I pulled back my foreskin, rubbed gently, and was rewarded with a few millimeters more of warm pussy.

Perhaps the humid night helped, perhaps my sister had started an erotic dream. Whatever it was, she became wetter and I was able to get half my seven inches inside.

She moved, and I froze. She muttered something inaudibly, shifted her butt and in doing so pushed back at my engorged cock causing most of the rest of it to disappear inside her. Frozen in fear, I waited for a few seconds, but soon my lust overcame the fear and I became aware of the wet heat inside my sister.

There she was, face down on her bed, with me holding my torso off her with my dick in her pussy. If she woke up, or if my mum happened to come in and check -- she still did sometimes -- there was no defence against what I was doing. So I just did it.

Gently, so gently I pushed forwards. As I sank fully in those warm folds I gasped, but I was so turned on that I almost didn't care if she woke up.

In seconds, my thoughts and deeds brought me to the edge. I didn't even need to thrust: Wow she's tight! And wet. And hot in there. My first pussy! My first fuck. It's so much better than... anything. Ever. Oh fuck I can feel her cunt! And my cock is burning so much. Oh shit. I'm gonna cum. I'm inside my sister's cunt and I'm nearly...

Then my heart skipped a beat as I realised I hadn't planned for this. Was I going to cum in my own sister? Maybe get her pregnant? If I jizzed outside her it'll be pretty fucking obvious! But it had got out of my control. I was cumming and I suddenly didn't care.

I pulled out just as the first spurts started, unloading my ropes on her pussy lips and butt, some falling onto the sheet below her glistening pussy. Pulse after pulse, hot and gooey, until I was spent. I congratulated myself on my achievement, then reality bit hard. I'd just shot all over my sister and she was gonna notice. What to do?

I knew sometimes if I jizzed on myself it would dry on a night like this, perhaps even the sheet would dry, but what if she woke in the next few hours?

I thought the few drops on the sheet would be OK. Maybe she'd think it was her own sweat. As gently as I could, like a thief covering his tracks I spread the goo with my hand. It was easy to coat Janine's butt with a thin layer of cum, but I'd dumped most of it on her pussy lips.

Putting a finger in there, I intended to scoop jizz out and wipe it on myself. Janine's reaction changed my plan.

Not knowing where to find a clitoris, I stumbled on the discovery by accident. The wet coating of my cum served as a lube as my finger glided over it, and my sister cooed in her sleep and opened her legs some more. I lost my fear and it was replaced with youthful experimentation. I touched the spot again. Nothing, until I moved it -- there -- and Janine gave a "mmfh" in her sleep followed by a sigh. This was too cool! Not only was I spreading the evidence of my incestuous invasion, I was turning her on! Without a care, I slipped my hand into her wetness. Curling my middle and ring fingers, I penetrated where my cock had just been and waited.

Slowly, almost imperceptibly at first, my sister pushed back at my hand. I was sure she was still asleep. Shit, if she woke and saw her brother fingering her she'd go apeshit. Of course she was asleep! But I didn't care. Janine's hips rose slightly. She wasn't bucking at my invading fingers, more like a push-and-squeeze from her cunt. I was grinning like a mad cat.

I hoped I'd wiped away my own creamy stuff by now, because I was going to see if I could make my sleeping sister get off. I'd never seen a girl orgasm before, even though I'd tried to get Sally Hawthorn off in the back seat of her dad's car once.

By now, Janine was breathing heavily. I knew nothing about pleasuring a girl so I got a delightful surprise when she stopped breathing, gripped my fingers internally, and moaned in her sleep.

Is she gonna...Oh man!...I'm making my sister cum! She's super-wet now! I can feel it.. She just came!

Without knowing why, I just let her waves wash over until she settled, breathing more normally. My fingers slipped out, and I practically ran back to my bedroom.

That night I jerked off twice. And once more in the morning. All I thought about was the fact that I'd fucked my sister and fingered her to orgasm. If I was lucky, tonight would be a hot one too.

Recap: My sister Janine and I are the same age, 18, but not twins. Janine is five feet 9, with curly brown hair to her shoulders and fair skin. She's a little plump. 

Last night I sneaked into her room, got behind her while she slept on her stomach and fucked her. Then I fingered her and I swear I made her cum in her sleep. Today was a very hot day, so hot that even in the air-conditioning I wore just shorts all day; Janine wore her bikini. She'd put on a kilo or so recently, so I loved the way her bum stretched the red fabric and the top cupped her tits snugly. I hadn't seen her in bra or bikini for a while, and noted she'd developed well in that respect. I guessed maybe C-cups, bordering on D's? Anyway, they were ample and held my gaze every time she moved. 

After dinner, I chatted with her: "Gonna be hard to sleep tonight, Nini." (It was my childhood nickname for her). 

"Sure will." 

"Sleep OK last night?" 

"Yeah, OK but not great. Mind you, I had a bit to drink, so that might have helped. I expect I'll toss and turn tonight though." 

I hoped not. 

Thankfully a cool Southerly change came through at 8 or so that evening and took the temperature down to comfortable levels. Janine stayed up watching TV, now dressed in the same nighty as last night, ready for bed. She sat with her legs bent underneath her, unaware I'm sure that I could see a triangle of white cotton between her legs, pulled tightly against her so that I saw three distinct lines - pussy lips and slit - for three or four centimetres. Sitting there in silky-smooth soccer shorts and T-shirt, my dick rose in salute. For the first time I realised how erotic the shiny fabric was against my cock. 

Being sure not to stare, glancing occasionally at this delicious sight I thought I saw a darker patch right in the middle. I fantasised that she was horny and getting moist there. On my third or fourth look I made the mistake of lingering too long. Janine looked at me and must have realised where I was looking. She adjusted her pose and I no longer had the view, so I pretended to watch TV with her. 

Maybe five minutes later Janine stood, walked towards the door, then cursed as she dropped something or other. With straight legs, she bent to pick it up. I have no idea what it was - my eyes were glued to my sister's bum, panties and camel-toe, pointing right at me just two metres away, nestled as they were in those lovely little cotton briefs. 

My jaw dropped, then I wrenched my eyes away. Janine disappeared for a minute then came back and sat again, chastely, not showing much of anything. 

My cock was enraged. Then my mind went through what I'd seen: Oh man that was hot. Slit, all the way, bum crack too! Oh, I know how firm those pussy lips are, and now I ... Wait! She bent over like that deliberately! She always bends from the knees like an old maid, even in jeans or whatever. Did Nini just flash me? 

My dick didn't care whether it was deliberate. He wanted action. Later on, he got it. 

Maybe two hours passed. I was back in Janine's room as she slept, still wearing those silky-smooth shorts, gently stroking my cock through them while I watched Janine's tits rise and fall in the moonlight. She was on her back, one leg straight and the other slightly crooked but I could not see anything. I was in the shadows, hoping for a chance to repeat last night's adventure. 

Bending awkwardly I managed to see she was still wearing those white cotton briefs. Gonna be hard to get anywhere now, I thought. 

Janine stirred and stretched her hands above her head. Shit! She was waking up! Somehow I darted through the door and closed it without creating a noise, and hurried to my own room. I held my door open just a crack and watched. Janine's silhouette went to the bathroom. I heard her peeing loudly, the flush, and then she went back to her room. 

I lay there awake and horny for maybe an hour, then sneaked back in. Her door was closed, and I suddenly realised this is the part where I'm most likely to get caught - she could be sitting on her bed and I wouldn't know until I'd opened the door, and at 2 am there weren't many valid reasons for me coming into her room. If challenged, I thought I'd say I heard a noise and came to check. Might work unless I was busily trying to get my dick in her. 

In the end I jerked off and jizzed in my shorts while I stared at her heaving bosom. Not as good as last night, but I got off all the same. 

It was three nights later when things took a new direction. Janine went to bed early - about 9 - so I figured by 11:30 when I went up she'd be fast asleep. But a crack of light around her door showed she wasn't. I peeked, fully aware that I'd be illuminated if she looked my way. But she was on her back, eyes closed. My heart leapt. My sister was completely naked, I saw in the dim light from her bedside lamp, legs wide apart, two fingers inside herself, the other hand pulling at each nipple in turn. 

I heard her low moaning now, and instantly I took out my cock and stroked myself. In a flash I decided to keep looking - if I got caught I'd try the old 'what did you expect with your door open' line. Janine's fingers were moving fast inside her pussy, mine likewise on my shaft. 

Suddenly Janine looked towards me. A second passed before she threw a pillow at me and pulled the bed-covers up. Ashamed, I lost my nerve and ran back to my room. My erection persisted, but I was racked with guilt. Eventually I drifted into sleep. 

I don't know what time it was, but my sleep-fogged mind began talking through the fog. Oh, cock hard again. Nice though. Sleep returned, then my dreaming mind spoke again: Nice! Girl riding me. Who? Might be Carol Burgess. I like her. Smooth thighs, feels like. And wet. And strange noises too. 

Noise? Wetness? Dreams are indistinct, vague, fleeting. I opened my eyes, and looked straight into my sister's face. it didn't register for three or four seconds, by which time I'd realised Janine was on my cock and gently riding me. The thighs and wetness were real. The noise was the faint creaking of my bed. Moonlight filtered through and revealed the scene fully. Janine was in a T-shirt and knickers. She had pulled the crotch of her panties aside, sat on my cock, and was gently, slowly lifting and squatting back on my nocturnal hardness. 

There was no doubt now. She was looking into my eyes, smiling, and put her finger to her lips: "Ssshhh". 

I rested my head back on the pillow and watched her face. She smiled all the time. She wasn't just taking pleasure, she was using her womanly guile to give it too. I reached for her breasts and cupped them half in trepidation, half fearful that she'd pop like a balloon at my touch and the dream would be over. 

Janine reached, grasped her t-shirt and lifted it over her head. Her magnificent tits jiggled free, and there they were. Nipples hardening, round and firm; that vision of my sister's breasts is imprinted on me now, all these years later. I'd seen her pulling at the nipples earlier, and I did the same. Immediately she bucked on my cock, squeezing me with her pussy, and threw her head back. Then she bent to me and whispered in my ear: "Gently. Let me do it all. We can't make any noise." 

So I just cupped her weighty orbs from below and let my sister rotate her bum and stir my cock, sometimes with a hip thrust, others not. It was too much. I grasped her hips and tried to urge her off me, I was close to losing my wad and didn't want to cum in her. 

My sister just smiled and shook her head; She wasn't going to lift off me, and pushed hard so my pubic mound was squished against her wetness. Feeling the familiar tingle, I pushed back at her as my balls tightened in advance of my release, and it started. Ropes of hot cum splattered my sister's insides, my dick twitching and spewing incestuous cream up into her. My mind blanked, went purple, senseless, while my seed jetted. 

Some seconds later my senses returned. Janine bent low, her tits crushed against my chest, and whispered: "You think I didn't know when you fucked me on Friday? That's twice you got to cum. You owe me. See you tomorrow and I'll tell you how to pay up." 

I was still hard in her, but she eased away and left me with a dollop of cum and pussy juice on my stomach. Then she was gone.
