He said that one of their most stimulating sex games was role playing…pretending to be someone else.They apparently, would like to play the role of ...randparents to their very young grandson. He went to tell me that I must play the horny young virgin son who has been sent to his grandparents by his up tight mother because she has caught him wanking into her knickers. Also he was masturbating a lot because when she changed his sheets it was stiff as board through dried sperm. The mother thinks. Sometime she even intimidated me. “But; OK,” Isaid and looked to Enzo. “Come on baby.” I said and hehopped up onto the bed gladly.Niki wasted no time, and neither did Enzo, as soon asshe cupped his cock, it started to grow. Niki loweredher head and took the end of his cock into her mouth,then back off. “It’s different then a man.” She said, Ionly handed her the lip balm and mouth spray then wentbehind her and started sucking on her cunt.. Lisa had made coffee and used the last of the bacon to knock up a few sandwiches which were gratefully received by Rob. As I half-expected might happen Liz came breezing in shortly afterwards with her usual “It’s only me” greeting as she opened the door. She disappeared straight through to the kitchen to speak to Lisa, but not without taking a long, lingering look at Rob.

I was standing there shirtless, pulling my pants down, becoming more excited the more exposed I became.Finally, I convinced myself. I walked around to his side of the bed, pulling out my dick in the process. I began stroking myself as I stood over him, inches away from his face, believing there was nothing wrong considering what had happened the night prior. I pressed my cock against his lips and began dragging it up and down.I felt his mouth move, as if.
