Knowing what was expected of her, Allison went over and gave her brother-in-law a beer and sat next to him. He put his arm around her and pulled her c...oser to him, and then leaned over and kissed her on the lips. She returned his kisses as she felt his hand squeeze her braless breasts through the thin material of her dress.Brodie felt Allison’s nipples harden and knew she was getting sexually aroused. He removed his hand from her breasts and laid it on her bare thigh. She spread her legs a. I sucked and slurped on his stiff cock as I wrapped my hand around his shaft. I squeezed it tight and he moaned softly.

His breathing became labored and I knew he was close.I stroked the base of his cock as I fucked his cock with my mouth. It slid down my throat repeatedly and my nose bounced off. I could feel her breasts pressing against my back. She spent some time caressing my nipples, which are actually fairly sensitive and that felt great. All the while, she was pressing against my back and stroking my chest, stomach and arms. The feeling her breasts pressing into my back was intensely erotic. Then she told me to wash her back, so I did the same thing, soaping her up and stroking her up and down, including her anus, running my fingers almost all the way to her vulva. Then I hugged. Tim rubbed his dick and balls, putting a show on for me. He reached out and pulled me to him, and guided my head to his crotch. As I licked the base of his dick then balls he moved me around till my butt was up and facing him. He reached between my legs and stroked my dick with one hand and caressed my balls with the other. Lifting his semi hard dick I licked around the head and piss slit before sucking it into my mouth. Tim moaned softly and said you've learned a lot in a short time. Releasing.
