I droped my shorts and began to jerk to that. I had to be very quiet so i wouldn't make any noise that made him know I was there. I watched him mastur...bate until he came on his belly and then I had to go to the bathroom and finish up so i wouldn't cum in the hallway. That would have been hard to explain...I got lucky two other times seeing him masturbate but the real jackpot came when his girlfriend came to spend a weekend with us. I had met her once before. She was kinda chubby but that right. .. fuck my ass like that.... fuck me!!!" he said. Repeatedly slapping his ass and grabbing onto him, spreading his ass apart while I fucked him. Seeing him bounce on my cock made me so horny. I reached up and grabbed him, hands all over his chest as he looked down at me, smile on his face as he thrust his ass up and down my cock. "your gf fuck your cock like this? huh? does she?" he asked. "Shut up... " I said as he continued on.. "ohh… you mad you like this ass better than her pussy? you like. There sat in a wooden chair in a corner was Zack Crawford! I'm dreaming, this is just some terrible nightmare. I closed my eyes shut for a few moments and counted to five in my head before opening them again and I shrieked out in fright when he was still there and I hadn't been dreaming.Zack was six foot and wore the black tuxedo I last saw him in four years ago at our high school prom. His hair was dark and swept to the side like a guy from a boy band. He had the bluest of blue eyes. Zack. As I stood and watched, I started getting hornier, and for some reason instead of noticing mom, I started noticing Karen. She was pretty much the opposite of mom. She had large breasts, and was kind of big all over. Not overly heavy, but probably about 180 pounds or more. I really hadn't noticed her much before, but she was really looking nice to me right now. She had blonde curly hair, and was wearing a dark green skirt and button up blouse, and black stockings and heels. As I said, she was.
