My s****r's Bottom

... French knickers. The warmth of her beautiful bottom encased me in a haze of lust and instinctively I started moving my cock between her globes. And would you believe my randy s****r moaned and started to squeeze me and massage me with her bottom? After so many hours of being so close to her perfect arse I was masturbating myself with it, and she was enjoying it too! Her hand pressed mine more firmly against her breast as we moved together to trap and stroke my cock. Her knickers were getting wetter and wetter as my pre-cum soaked into the fabric. It was so warm and very wet between her cheeks that I could hardly feel the fabric at all. My cock was harder than it had ever been, so rigid it hurt. The tip was almost too sensitive to touch but I thrust it firmly in long strokes between her cheeks. I was in my own private heaven. Then heaven became even better; I felt her wriggle a bit and her hand guided my cock under the loose leg of her knickers and between the cheeks of her bottom so it was sliding over her anus and along between her naked, wet cheeks. I whimpered with pleasure as she matched me thrust for thrust and squeezed my hand onto her breast. I knew I couldn’t last long; it was just too erotic, too arousing feeling her cheeks wrapped round me. As I felt the rising in my cock I kissed her neck and told her I was going to come. “Yes, come.

I shot my liquid tribute to my s****r’s beautiful arse all over the object of my desire and lust. I filled her knickers with cum. I came more than I had for ages, since those teenage fantasies of playing with her backside; and now here I was masturbating with the real thing. My cock spurted and spurted all over her knicker-covered bum. I kept spurting until I was empty and satisfied with the best orgasm I’d had in ages. I lay between her cheeks twitching as I gasped and panted and she squeezed my hand hard. “Fuck Matty, that was so horny! I’m all wet.” I slid my hand down to her knickers. “I want to make you come too.” “Mmmm! Yes please.” I lifted the waistband of her knickers and felt for the first time her soft, downy pubic hair. She parted her legs as I slipped a finger between the folds of her cunt. She was so wet! Her clit was erect with excitement and she gasped when I circled it with my finger. Leaning over her I kissed her. I kissed my s****r like I’d never kissed her before, deep, passionate and heavily sexual. Her naked breasts thrust her erect nipples against my hand and possessed me in their soft warmth. She was panting and wriggling as I played her delicate clit with all the passion she’d given me and the whole reservoir of obsession ...
