"All clear."
My right hand remained on her breast. My breathing was shallowed, my heart racing. This was wrong, so wrong! What if she woke up? Except she was out like a light, and would wake up slowly, at which point I could pretend it was all just looking after her. I lowered my left hand back down onto her chest, although this time I went a little lower, cupping her tit. My right hand slipped down to join it.
The feeling of her huge tits in my hands was heavenly. I squeezed, slowly at first, savouring it. My hard-on was raging, begging to be set free. I began to squeeze them harder, watching the nipples harden. Was she able to get aroused, while unconscious? Well, the mechanism was clearly independent from conscious thought. I felt her tits swell to full size, confirming that she was at least a double D bra size. Her rock-hard nipples were large, and a deep shade of pink.
I grabbed the towel, bunched it up and used it to smother the phone lying on the floor, with the emergency services still on line. I bent over, slowly, and lowered my mouth onto her tits. Very carefully, nervously, I began to kiss the nipples. I lightly brushed my tongue over the tip, before going back and licking again, harder. I opened my mouth further and began slowly sucking on her massive boobs, running my lips and tongue along the side. I pushed my face into the cleavage, going as far as I could before I had smothered myself, using my tongue to lick up the inner sides of her boobs. I repeated this, increasing my vigour with each suck. I felt her chest heave with unconscious pleasure.
As I ran my mouth and tongue over her, my hand went down and gently stroked her clit. Just knowing that my fingers were playing with her clit drove me crazy with arousal. I dropped my other hand down and began slowly caressing my bulge through my trousers. Undoing the zip, I dug my hand into my boxer shorts and began stroking my dick. I grunted quietly into her tits from the pleasure.
I couldn't believe this was happening. It was wrong, so wrong, especially with her in such a bad state, but I was dizzy with lust and excitement. I was sucking my big sister's tits! Just saying it in my head sent a rush of delirium running through my spine. I no longer gave any thought as to what would happen if she woke up - I was far gone from that level of rational thought.
After a few minutes of sucking, I couldn't take it any more. My body ached to fuck her. I grabbed her and roughly flipped her over onto her back. I climbed on top of her, spreading her legs apart. I expected some difficulty, but it seemed I had got her fully wet. I thrusted downward, ramming my cock into her. The glorious, wet friction between dick and pussy sent electric sparks running through my body, and I moaned out loud. I held there, my dick embedded deep within her, before starting to slowly rock up and down, easing my dick in and out of her. I had done this before with other girls, and my moans increased ecstatically when I felt the familiar, intense pleasure build up deep within me. Soon I was ramming myself into her, slapping myself against her wet thighs and pussy. I was harder than I had ever been before.
Driven by my fervent arousal, I stuck my finger in my mouth, wet it, and reached down to her ass. My finger slid in smoothly; she had been fucked in the ass before! The hot-blooded stimulation that gave overtook me. I pulled myself out of her pussy, moaning as I left her, before pulling her legs into the air. I positioned my cock against her ass and slowly pressed forwards. She was tight, but I managed to slide myself into her ass. I let out a quiet, shaky moan as pleasure engulfed me. I began to rock to and fro, easing my cock in and out of her ass. I closed my eyes as ecstasy engulfed me. I kept at a slow pace, building up a strong pleasure deep inside of me, feeling my cock explore every corner of her ass. My moans were fragmented and breathless.
As the deep, internal pleasure became more and more acute I began to get faster and faster, my dick thrusting into her and slamming my balls against her ass. With each stroke I increased my speed, and fucked her harder too. I squeezed tightly on her left tit, which was bouncing up and down in time to my thrusts, and moaned out loud. Her ass was clamped tightly around my dick, accessing pleasure spots that I didn't even know existed.
Suddenly, she let out a moan.
I would like to say that I froze in panic; certainly, my brain did, but maybe that's why I continued to thrust into her as she slowly gained consciousness. I couldn't even begin to find words to say, but my moans were clearly not controlled by coherent thought, because they carried on with increased intensity. She was waking up slowly - or, she would have been had I not been thrusting in and out of her. She gave a sudden gasp and her eyes bolted open, staring at me in confusion and panic.
"Jamie?? What the fuck??" Her voice was high pitched and breathless. She realised what was going on, and tensed in shock, squeezing her ass tight on my cock. The increased pressure made her shudder with involuntary pleasure.
"I'm fucking you, that's what," I grunted, driving myself into her. "God you're hot."
I had no idea what brought that on - that was my dick talking, and it didn't care much for my sister. I was about to stop, to pull out, to apologise, when she let out a tiny whisper.
"Yes".
This made me pause. I looked at her, in shock, my dick resting on the entrance to her ass. I stared deep into her eyes, and I saw the intense lust that I felt reflecting back at me. Arousal, as I had never felt it before, flooded through me.
I rammed my cock deep into her ass, and the volume of her scream of pleasure was matched only by my own. Her hands shot round and grabbed my bum, squeezing tight and pulling me into her. I held there for a second, before pulling out and slamming back in, her hands driving me into her. I began to build up momentum, fucking her hard. Feverish pleasure coiled itself deep inside me, building up at the same rate. Kathy's whole body was flushed, lying there naked and willing. I squeezed hard on her boob and she groaned with pleasure.
She cried out as I fucked her. "Take me, little bro! Harder! Yes!" I could see she got intense excitement from calling me "little bro", and fuck, so did I.
Wanting to maximise her pleasure, I pulled out of her ass and was back in her pussy within seconds. Her moist warm cunt was heavenly against my raging dick, and I shuddered with pleasure. I began to stroke her clit with my fingers, her moans becoming more and more urgent. My cock spasmed with sensitivity, as it was overloaded with intense pleasure. I rammed into her harder and harder, panting hard and moaning with delirium. I could feel an orgasm build up inside me, and judging by the sound of it she could too. My strokes on her clit had become vigorous rubbing, and she began to squeal with pleasure.
We seemed to climax at the same time. I gathered every last reserve of energy I had left and thrusted into her as hard as I could, which was more than enough to push us both over the edge. It was released like a wave. Thick wads of cum pumped out of me and into her, and her pussy clenched hard. Our bodies shook against each other, her tits pressing into my chest. We both gave one final simultaneous moan, riding the orgasm on for about a minute before it began to die down.
She lay there, and my arms straddled either side of her head so that I was over her, my dick still inside of her. She looked up at me. She smiled, her eyes glazed over and she passed out on the bathroom floor.
