Waking in the dark

I woke in the dark confused. Someone was wrapped around my body, breasts pressing into my back. Then I remembered Cassie was staying over. Then I remembered her fucking me while she slept, dreaming I was David, her ex. Except at the end when she said, "Thanks, John."

Then I realized that her hand was stroking my johnson. My sister had a very active dream life, I guess.

"You're so hard, David. Shame for it to go to waste," she whispered in my ear. Then she pulled away from me and rolled me on my back. Still holding my cock, she straddled me. She whipped off the tee shirt I had given her. In the moonlight coming through the window, her boobs looked fabulous with fat nipples pointing straight at me. She lifted up and maneuvered my cock into her hot wet hole. As she slid down my cock, she moaned. She leaned forward, putting her boobs close to me. I reached up and cupped them, squeezing them as she started to bounce on my cock. "Oh, David, you fuck me so good!" she said as she looked me straight in the eye. She appeared to be sleepwalking, eyes open but not recognizing me. I guess sleepfucking would be a more apt word. I was not going to let that get in the way of fucking the hell out of my sister and busting a nut inside her.

I pulled her forward and sucked one of her plump nipples. This made her groan above me. "God, David, you always get me so hot and horny!" Her moans and squeals were so sexy. After letting me suck her for awhile, she sat up straighter and just pounded up and down. Her jiggling tits were erotic art in motion. I reached down and rubbed her clit, which made her moans go up an octave. "Oh, God, I love riding you Cowgirl! You can touch me so many places, David!"

Then she dropped down and stayed down, grinding her pussy hard into my cock. She let out of shriek of passion as I felt her pussy clamp down on my cock, squeezing it hard as she came. Then she bucked like a bronco, jiggling like crazy, and singing out her climax. I thrust hard up into her and unleashed my swelling cock, shooting several volleys of hot sperm up inside her quivering cunt. After an amazing explosive orgasm, Cassie slumped on top of me, rolling to the side. She was asleep before her head hit the pillow. I cuddled into her body, putting my arm around her and cupping her boob. I ground my cock into her ass and went out like a light. What a fuck!
