Starting slowly at first he fucked her carefully but was soon told by Sarah to go faster, this he did eagerly. He was fucking his sister forcefully n...ow and the more he did the more she loved it, she pushed her body down to meet his strokes and now she was gasping for air. She could feel her muscles tightening inside milking his prick, he didn’t know how much longer he could last. It didn’t take long before he could feel the anticipation of his orgasm, he had no time to warn her but Sarah. He reached down and touched my breasts with both hands, so gentle I almost came right there. I looked down at his pants and I could see a huge bulge in them. My head was spinning, and my body was aching for the bulge in his pants. My hand went down to touch him, and he bent down to kiss me. I unbuckled his belt, and he stopped. At first I thought that was the end of it, but then he helped me with the belt and unbuttoned his pants. He then took his shirt off and spread it out like a blanket. It certainly wasn't the first time I'd gotten hard around Kim, but now my cock was swollen almost to bursting. Kim noticed and giggled. "He says yes," she said happily, giving my cock a squeeze through my pants. "Let's go upstairs."Scant minutes later Alex and I were buck naked in the master bedroom watching Kim do a sensuous striptease. Alex was seated in a large armchair not far from the bed, idly stroking his cock, which was every bit as hard as mine. I stood a few feet away, carefully. I had also hired a script girl to make sure things followed the story and looked good. Her name was Sally and she was 19. She was a cute petite thing and I think she had led a rough life. I handed her a script and told her to go and review it with Steve. It was a pretty basic one. I was to play a housewife home alone. Steve was a repair man who had come to fix my plumbing. I went to my bedroom to change into a sexy outfit. When I came back into the den I was wearing a short black baby doll.
