I pulled my cock out of his ass and fell back onto the bed. I lay there for a while. Tom stood up from the floor and looked down at me. “Your turn,�...� he said and grinned at me. He picked up my legs and slung them over his shoulder and pull me towards his growing cock. I could feel it as it pressed against my ass hole. He urged me to relax and when I did he forced his cock into my hole. It hurt at first but I started to become aroused as his cock massaged my prostate. I started to groan while Tom.
