I reached up as I was licking her and let my hands run lightly all over the soft flesh of her breasts, loving the rubbery feel of her nipples under my... fingers. Suddenly, she cried out, "Jason... take me now, please... I've waited so long," and pulled me up to my feet. I kissed her deeply, slipping my tongue past her lips and caressing hers, pausing long enough to drop my pants and boxers, then moving between her spread legs and grinding the length of my cock against her hot, wet cunt.Her moans. I knew that there was only the thin material of my pajama as well as her own pajama that was separating my cock from her girly rump.Before that night, it had never occurred to me that my sister could be sexually attractive, but now that I could feel her round buttocks, - in the last year Linda's body had begun to change into that of a woman - I began visualizing her in a completely new perspective. Her hips had begun to flare out and her breasts were now the size of large oranges, even the baby. ” I did as I was told and she was obviously pleased because she was panting in a few minutes and grinding her pussy in my face. She smelled like peaches (really) and I was in heaven. “OH GOD CHLOE”, said Katie, “wait until it’s your turn. He is soooooooo good”. I inserted my middle finger inside her while licking in long broad flat strokes with my tongue from her vaginal opening to her clitoral hood where I paused and thumped her button with my tongue. That made her crazy. My middle finger. She started to buck in to my face, gyrating herself while holding my head down in to her pussy.She let out a grunt then started to pant, her breathing getting deeper by the second as I sucked on her clit. Lisa came and I was forcefully held between her legs as she lifted herself off the bed as her orgasm took hold.Lisa lowered herself back on to the bed then I hooked my fingers over the waist of her satin knickers and started to pull them off. She dug her heals in to the bed to lift her arse up.
