I lay in the dark listening. I didn't want to have to listen but the only way to block out the sound was to smother myself with a pillow. The parents were out so my sister figured she could orgasm as loud as she dam wanted. Her moans of pleasure echoed throughout the house along with the occasional grunt from her rat of a boyfriend, who normally invaded through the window of Becka's large window. Squeezing his big fat head through along with his big fat ass. But today, he'd waltzed in through the front door as if he owned the bloody place.
I would have thought that Becka, my younger sister by 18 months would have kept her screams to level they're at when Mum and Dad are home. For the sake of me at least!
And so they went on bucking, until I could stand it no longer and I got up to go for a drink. As I rose, I was disgusted with myself to find I had a hard-on! "Urggg! I get excited by my own sister!" I carried on thinking as I went onto the landing.
"Hey, it could be anyone, my dick doesn't know who it is, it 'ain't my fault." And so, my conscious thwarted I went down stairs. I got a glass of milk from the fridge and stood while I sipped at it. Back upstairs I ran into Becka. She looked a wreck. Completely naked, (I'm not complaining about that. Man she has a great body) her hair was pointing in every angle and she looked tired and flustered and red in the face. Even in the dark I could make out the fresh cum dribbling down her leg. I grinned. "Having fun?"
Becca seemed not to notice me and stumbled on into the bathroom. I went back into my room. I got back into bed and reflected on what I'd just seen. It was so HOT! I knew then, that I had to have her. But not now. In the morning. I meant to have a wank to satisfy myself but instead I drifted off into sleep.
I woke late and still quite drowsy, but I remembered my quest to fuck my sister's cunt so I rose immediately and went for a shower. As I passed Becka's room I saw her lying half awake, naked on top of her bed. I paused for a moment to admire her body, and then went into the bathroom. As I stepped under the hot water I noticed my hard-on but I ignored it and scrubbed myself clean before cleaning my teeth. In true bloke fashion, I was in and out in under 10 minutes. I walked back to my room naked and dripping wet.
I picked up a towel from the airing cupboard and took a peek in Becka's room. She was still in a half awake state but was now idly fingering herself. While staring at the ceiling, her mind elsewhere, she rubbed her little stiff clit and spread apart her pussy lips. Every 10 seconds or so, she slipped in her little finger and emitted a little gasp and withdrew it. Her other hand was caressing each breast. Cupping one, then pinching a nipple then swapping over.
