One Morning

I WAS woken an hour or so later by the sound of the shower running. Finding I was hard again, my hand instinctively went down to find my erection, first stroking along its length, then slowly peeling back my foreskin, feeling the pleasure of the skin rolling against my enlarged glans. As my hand returned to my 15-year-old cock, I wondered how I could be so horny again so quickly, after achieving everything I had dreamed about for so long. I had hoped once would be sufficient to banish such lust from my mind. Instead, my thoughts took me back to the events of earlier that morning, remembering how sexy it had been, as I slowly massaged my stiff prick ...

 

DESPITE HAVING thought about it many times, it had taken some nerve. I'd almost tried the day before but had given in at the last moment. Days were running out, soon the school holidays would be over, and the opportunity would be lost. As yesterday, I waited patiently for my parents to leave for work, thinking about what was to come, letting it get me aroused and occasionally I toyed with my erect prick. When all was quiet, I got out of bed and put on my dressing gown. As I walked from my bedroom across the landing, I told myself I would use the speech had dreamed up, the one saying I had read how good sex could be and what a shame it would be if we regretted when we were older that we hadn't started younger, followed by an emphasis on the need for young bodies to have sex. When I reached my destination, most of that went out of my head.

My 13-year-old sister was lying in bed reading, her brown curly hair framed by her pillow, duvet tucked demurely just below her armpits. She looked up surprised when I entered.

"Morning," she said, smiling. "Is everything ok?"

"Morning," I replied, trying to smile and remain cool while being in turmoil within. "Sleep well?"

She nodded in reply.

Calling her by her name I ventured, "Have you thought much about sex?"

Unsurprisingly, my sister shot me a bemused look, then giggled.

"Er, not really. Sometimes my friends talk about it."

"Have you ever tried it? Even on your own? Did you like it? Come on, you can tell me."

My sister blushed slightly and looked away. "I touch myself sometimes ... down there. It's nice."

"I've heard it can be fun." At which point I unfastened my blue dressing gown to reveal that I was naked underneath, my erection clearly in view. Suddenly I was unsure what to do. Was it too late to stop now? What was I going to do if she simply refused?

"Can I ... can I get into bed with you?" I asked.

My sister did not reply, she just looked at me slightly blankly, her eyes dropping to my erect prick. Then she closed her book and put it down by the bed. I took this as permission to proceed, shrugging off my robe then climbing over this sister, my prick bobbing in clear view, to lie naked with my back against the wall facing her recumbent form. I cuddled against her, pleased that she didn't pull away, my right arm looping over her waist. I nuzzled gently against the soft warm skin of her neck, taking in her scent, then kissing her gently just below the ear.

She squirmed slightly and giggled, seemingly unsure of what was going on or what to do. I noticed that when I kissed her ear and then her neck a second time, she was more relaxed. We lay there for a while and then my hand slowly moved up over the bedclothes, my fingers eventually venturing onto the material of her white, patterned cotton nightdress, stroking at the material and the skin beneath.

"I'd like to try a few things," I said "is that ok?"

My sister nodded, if hesitantly, so I started to clumsily undo the buttons at the top of her nightie, exposing the creamy while flesh below, which my fingers started to gently stroke, running along the join where her neck met her shoulder then down along her collar bone, occasionally dipping under the fabric, enjoying the soft warmth of her skin.

"Is that nice?" I asked after a while. "Do you like it?"

"Yes." she whispered as though embarrassed to admit it.

Taking this as an indication I could proceed, I adjusted myself, lifting then slipping under the duvet so my naked body was pressed against my sister's side, ensuring the top of the duvet was pushed downwards as I did so, revealing more of her nightgown, including the slight swell of her chest. I could feel her warmth through the thin material and knew my sister would be able to feel my erection against her thigh. My right hand moved across the top of the duvet to creep onto the fabric of her nightie just below her breasts. Half expecting her to object, I was relieved when she let me slowly trace a line first through her cleavage, and then round to her left, up the gentle swell and to her left nipple. With a pounding heart, I felt her nipple harden under my finger and pressed against the peak through the fabric, pleased when my action elicited a small, contented sigh from my sister. I continued to trace patterns over and around her tits until I decided she was relaxed enough to continue. I slid my hand under the covers, down over my sister's hip, resisting the urge to investigate what lay between her legs, then lower until my hand found her exposed leg, which I caressed. Then I moved my hand upwards taking hold of the hem of her nightie. I tugged at it. It moved a little, but I was then disappointed that I was unable to pull it upwards.

"Can you help me?" I asked gently, slightly surprised when my sister used her legs to raise her bottom, allowing me to slide the garment upwards, until the hem was around her tummy. I settled back into position, my engorged prick now pressing directly against her naked thigh. Partially because I was unable to resist, partially as I wanted her to know I was erect and wanted her to understand she was the cause of my arousal I was unable to resist rubbing myself against the soft warm flesh. I slipped a hand under the bunched material of her nightie and slowly stroked over her ribs towards her breasts, marvelling at the smoothness of her skin. Again I found the slight swell of her left breast and then the peak of her nipple, except now I was no longer feeling it through the cotton of her nightdress. Almost unable to believe I was fondling my sister's breast I pushed my prick against her again. This time I caught her erect flesh between my thumb and forefinger, and the sigh was almost a moan of pleasure. Enthralled by the feel of her tits, I continued stroking, alternating between her breasts, tracing around and over her aureoles, toying with her small erect teats, while sensing her breathing deepen.

I shifted again reaching for the bunched material of her nightie to pull it higher. The girl understood what I was trying to do and obligingly sat upright, allowing me to roll the garment up so it was gathered under her armpits, exposing my sister's small, almost conical breasts which were topped with little dark pink nipples. She lay back down as my hand returned to her left nipple, her eyes on my hand as I again played with it.

Suddenly she sat up again, and I was afraid she was about to rebuff my advances.

"It's a little uncomfortable," she started, and my heart sank. "Let's get this out of the way."

To my delight she took hold of her rolled up nightdress and with a slight struggle pulled it off over her head, leaving her topless. To free it she had to raise her arms high, stretching her chest and emphasising just how small her titties were. Dropping the nightie by her bed, she settled back on her pillow.

I took a moment to take in the sight of my sister's exposed upper body, her slim shoulders, the peaks of her collarbone and the beauty of her developing breasts. Trying not to rush I ran my forefinger along her left shoulder, pausing at my sister's neck to stroke above her collarbone before trailing downwards to find her left breast once more. As my fingers resumed our fondling of her left nipple, I lowered my head to kiss her chest just above her right breast, pausing for a moment to see if she would object. I then ran my lips downwards until I found her right nipple, my tongue flicking out to lick the erect tip.

"Ohhh," sighed my sister quietly as she tensed in reaction. She pulled her hand free from where it was trapped down her side, bringing it up to stroke my head, just as I started to suck on her breast.

As my lips and tongue continued to pleasure her right nipple, my hand slowly traced down over her rib cage then under the duvet. I spent some time stroking her tummy and then continued on down. I stroked around her belly button then almost hesitantly ran a finger along the join between her panties and her tummy. Reaching her hip, I ran my hand down to her knee then slowly traced a line up the inside of my sister's thigh, pleased when the girl parted her legs slightly, granting me access to between her legs. I ran my fingers over her panties a few times, pressing lightly at first and then more firmly, trying but failing to identify parts of her vulva through the material. Moving my hand deeper between her legs I found the soft, giving area of the entrance to her vagina. I felt her express her appreciation by more firmly stroking my head while slightly pushing her breast up against my suckling mouth.

I traced a finger along the point where her inner thigh met her panties, sensing the slight perspiration on her skin, trying to slip a finger under the elastic.

"Hold on," said my sister. I felt my heart sink again and raised my head from her breast. Was she going to stop me now, having got so far? Instead, my sister pulled back the duvet dumping it on the floor, exposing her tummy and coltish legs, my hand still stroking the white panties that covered her sex, as well as exposing my naked body. The cool morning air was refreshing, and I realised how the heat produced by our two bodies had started to build under the duvet. The girl raised her bottom off the bed, took hold of her panties and pulled them down towards her knees, then she lifted her legs up and removed her underwear, slipping them over her feet. My sister lay back on the bed naked as the day she was born, seemingly unphased at being nude in front of her brother.

I stared for a moment down towards her lightly haired pussy, watching my own hand stroke over her thigh, then across her lower abdomen, my fingers barely brushing the edge of her pubic hair. Then I slipped my hand down to nestle between her legs, enjoying the tickle of her pubic hair on my fingers. I shifted back into my previous position alongside her, my head then lowered once again to her right breast, sucking on her nipple as my fingers started to stroke and explore my sister's sex. I found her slit first, running a finger gently along the tight join of her pussy lips seeking the soft area of her entrance again. I was delighted to find she was wet and slipped a fingertip into her vagina.

This time there was no mistaking the groan of pleasure from my sister. She demonstrated her growing arousal by finding my erection with her right hand, running her fingers along my stiff prick where it was pressed against her thigh. Not wanting to discourage her, I turned my body slightly allowing my penis to spring free. After a slight pause, her fingers found my cock, wrapping around it.

I ran my finger back up my sister's slit, pushing into her folds, parting her cunt lips, searching for her clit. I knew I had found it when the girl tensed and grunted, her back arching slightly off the bed as her hand squeezed my erection. I rubbed her clit again, feeling the little nub under my fingertip.

"That feels really good, please do that again," she said, turning to look at me then raising her head to kiss my cheek.

"I can do better than that," I said. I pushed myself up on one arm, returning the kiss with a gentle peck on her lips. Moving downwards, I kissed her right breast again, then leaned across to suck for a moment on her left nipple. Then I pushed myself upright and kissed her rib cage, then her stomach, then her hip, then her belly button. For a moment my sister didn't understand what I was doing. When it dawned on her she looked slightly shocked but without being asked, she pulled herself slightly higher on the pillow and moved her legs apart, allowing me to move across and kneel between her thin thighs.

I paused to study my sister's pussy, the first I had seen in real life. To me, her partially developed vulva looked beautiful, her creamy white skin covered by a thin layer of brown hair which thinned as the dark line between her slightly puffy labia curved down between her legs. I ran my eyes down her slim 13-year-old body, taking in how her breasts were rising and falling as she took deep, long breaths, then over her flat stomach down to her cunt. My sister's cunt. Momentarily I marvelled at having got this far.

I smiled back and lowering my head I gently kissed her tummy and then her pussy above her slit, slipping out my tongue to take my first taste of my sister's sex. I was surprised that her pubic hair felt so coarse and tasteless – somehow I had expected something softer. I ran my tongue through her bush, finding the start of her slit and tracing it downwards aiming to find the entrance to her vagina, picking up traces of my sister's love juices for the first time.

Aiming to help, the girl raised her right knee, resting it on the wall, adjusting the angle of her crotch and before I knew it my mouth was on her vagina and my sister was moaning in appreciation. Although my finger had touched her entrance minutes before, I was amazed at how wet she had become, but I revelled in the taste, made all the better by the fact that I was going down on my underage sister and that I knew I had initiated her arousal. I ran my tongue over her pussy lips either side of her entrance several times, licking away the tangy juices which had gathered there.

Bringing my hands to bear I gently parted her cunt slips and ran my tongue upwards through her folds, finding her clit and kissing it. Acting impulsively, the girl pushed her pussy against my face, rising her bottom off the bed and tensing as she grunted her appreciation. She relaxed again, breathing deeply as I pulled my mouth away.

I smiled up at her. "Did you come? Have an orgasm?"

Panting lightly, she smiled back. "I am not sure. I have never felt anything like it before. A small one maybe, I felt a lovely spasm."

"Let me see what I can do. Just relax and go with it."

I lowered my mouth back to her cunt, moving between kissing and sucking on her clit and my tongue pushing against her entrance. Her breathing deepened further and then she was coming, grunting and moaning as her body tensed and her first real orgasm flowed through her.

"How was that. Did you enjoy it?" I asked, raising my head to smile at her.

"That was amazing," she half-panted, trying to get her breath back. "I didn't know what I had been missing."

I lowered my head back to sex, running my tongue gently up and down her slit, trying to assess whether or not she was satiated. I knew she wasn't when I felt her right hand on the back of my head, encouraging me to continue. I caught a sight of movement above me, and looking up was pleased to see my sister demonstrate her arousal by rubbing her other hand over her left breast and then start to massage her nipple, moaning slightly as she did so.

At the end of my next lick downwards I paused at the entrance of her vagina, using my hands to part her labia, savouring once more the tart taste of her juices before pushing the tip of my tongue into her, eliciting another moan of pleasure. I pushed deeper, encouraged by her hand on the back of my head. I paused there, using my tongue on her as she moaned her appreciation.

After a while I moved upwards again, seeking to renew my acquaintance with her clit, first licking it with my tongue and then catching it between my teeth while slipping my right forefinger into her, pushing until my finger found her hymen. My sister gave a delighted shriek, almost sitting upright as both her hands cradled my head, before relaxing back onto her pillow.

I knelt upright, taking another look at my sister's body, which now looked slightly flushed and seemed to be covered in faint layer of perspiration. I glanced up to see whether she was looking at me, but her eyes were closed, as though she was waiting for the next moment of pleasure. Unable to resist my hands went down to my erection, toying with my glans and foreskin. She opened her eyes and smiled at me.

Smiling back, I knelt up then leant forward so my hands rested either side of her arms, before moving my knees backwards so most my weight was on my arms. This lowered my crotch towards hers, feeling the warmth of her vulva on my lower stomach, while placing my head almost over hers. I inched forward so the tip of my prick was just rubbing at the entrance of her cunt, sensing her warmth, her juices wetting my exposed glans where it peeked out of my foreskin. I looked from her erect nipples down to where my body pressed against hers, aware that with a simple move forward I could penetrate my sister. Then I brought my eyes back to my sister's face up staring intently at her, waiting for a sign that I should continue.

"Are you ok with this? I love you and I really, really want to fuck you, but you must want it too."

She looked hesitant. Torn by indecision. I guessed for her it was one thing to fool around with your brother, another entirely to let me to take your cherry and fuck you. But I could tell she was aroused, that she needed something.

"I'm really not sure. I'd like to try but it's a big step to let you actually enter me. I think we should stop here."

"Can I slip the head of my prick in, just to see if it will fit?"

"Ok, but go slowly, and if I say stop, then stop."

She pushed her head up from her pillow and kissed me with a peck on the lips before falling back again. Not wanting to let the opportunity go, I edged my prick forward, but it was too high to slip into her cunt. Frustrated I pulled back slightly, brought my hand to bear and held my penis in position as I pressed it against her entrance, felt my foreskin give a little, felt her wetness. I pushed my crotch gently forward and felt her pussy yield, so tight that my foreskin was pushed back as my glans popped into her vaginal canal.

She groaned with pleasure, before snatching a few words between gasps. "Stop, stop. We really can't do any more."

"Please," I begged. "We are here and it's now. I really want this. And you've enjoyed yourself, I know you have. We are so close."

I rubbed against her, causing to moan once more. I felt a slight resistance, realising the top of my penis was pushing against her hymen, the final barrier to all I wanted. I rubbed again, aiming to encourage to give her consent. I lowered my head to hers and kissed her on the mouth, a wet kiss with my own lips slightly parted, then pulled back.

She stared at me, trying to look serious while putting her own pleasure to one side. "Ok, let's ..." she began.

The sentence remained unfinished as I took her words as permission to proceed, pushing forward, sensing the resistance give, feeling my prick slide into my sister's cunt. At the same time I lowered my mouth to kiss her, my tongue finding hers, her tongue finding mine as we shared an incestuous, lust-filled brother-sister, life-changing kiss. Her instant reaction was to squirm under me a little as if uncomfortable, at the same time appearing to mutter something as we kissed, which passed as her passion took over.

As we continued to kiss, I pulled out, then back in, grunting as I did so. Her arousal was too strong and she was unable to resist, tensing her little body to meet my strokes, her breasts jiggling lightly, uttering small cries of pleasure that were muted by our kissing, feeling me slip deeper and deeper with each thrust. She pulled her legs up and her hands went up to stroke my back.

At the top of the fifth or sixth stroke my glans hit the entrance to her cervix. Hit by a wave of unexpected stimulation she came under me, a massive orgasm flooding through her, her cunt rippling around my intruding prick causing me to come as I shot my load deep into her vagina, pumping my semen into my sister. She broke the kiss, pushing her head back and groaning in ecstacy as she came, and I grunted with pleasure into her hair just above her ear.

As our breathing slowed, I pushed my body upwards, separating our bodies, my softening prick slipping wetly from her vagina.

I smiled down at her, but she frowned back. "I didn't say continue," she said, slapping me on the shoulder.

"When I asked you said 'ok'."

"I was going to say 'Ok, let's stop now'. I think you had better go. She picked up her nightie from the floor, holding it across herself as if now ashamed of being naked, wanting to hide her body. "Go on get out," she shouted.

"I thought you were enjoying it ..."

"GET OUT!"

 

MY THOUGHTS were interrupted by a soft knock on my bedroom door. Immediately any thought of coming went from my mind as I pulled my hand away from my erection. Before I could say don't come in, the door was pushed slowly open and my sister walked tentatively into the room, wearing her dressing gown and clearly fresh from the shower. She moved over to stand by the side of my bed.

She smiled down at me, and I found myself smiling cautiously back. Looking at me coyly and without saying a word, my sister undid the tie of her dressing gown, slipped it off her shoulders and let it fall to the ground around her feet. Underneath she was completely naked. I had a moment to take in the beauty of her young teenage body once again, from her clearly erect nipples atop her small conical breasts down to the slimness of her hips and sparely haired 13-year-old pussy. As I gazed, my sister reached down and pulled back my duvet, revealing my naked body and my hard cock. Without asking, she slipped into bed alongside me, grabbing my prick as she pushed me back towards the edge of my single bed ...
