The steady pressure got him all the way in so that his balls were resting on her well used pussy lips and he gradually pulled back out and started to ...uild up a rhythm. He grabbed her ginger ponytail and pulled her back harder onto his cock, pounding her arse, scrotum slapping her cunt. He stiffened as he unloaded, and at this moment I felt a hand fumbling at my belt. I turned to see a middle aged woman trying to get my throbbing penis out, and I thought about refusing. Too old, looked well. I didn'tthink anything of it and continued to watch tv.About thirty minutes later I heard him enter the room from behind me. Iturned my head and got the shock of my life. Dennis had turned intoDenise. She had done her hair in a more feminine fashion, was wearing ablue A-line dress that stopped several inches above her knees. Icouldn't tell whether she was wearing stockings or panty hose but herlegs were beautiful. It was topped off with a pair of matching threeinch heels. Dennis just stood. He had to know I was waiting for the opportunity to reciprocate. He even bent over a little. I reached between his legs and grabbed his balls and squeezed. He called out in pain. “Oh God, George! That hurts” I let up a bit, then squeezed harder. He moaned. My hands being soapy, I was able to roll his balls around a little in my hand. He moaned louder, but not entirely in pain I thought. “Tell me I’m a bigger stud than you.” “No way” I squeezed harder. “Oh fuck, man, that hurts me,” he cried.. She blushed furiously pulling it back into place, but I saw her checking the bulge in my trousers."I just don't know why I'm doing this." She complained. "It's so wrong, but feels so right."I stroked the side of her face. Her eyes closed and she almost purred. I continued moving my hand, sliding it down her elegant neck, tracing her shoulder and then sliding it inside her blouse, capturing the breast in my hand with the nipple between my finders."You do it because you're my mom and you want to.
