"One way mirrors" he said, where one could see into the next room or watch from there into ours. We walked over and I looked into one and there I wa... surprised to see Avis, on her knees, naked form the waist up, sucking on another man`s cock while yet another stood to her side, reaching down and slapping her tits hard. "God, I wish I could hear that" I muttered and the man told me I could by turning the little knob. I turned it up full and heard the man say to Avis, "You like that cock.

I pushed my cock all the way to the balls in one stroke. I started fucking her real slow, it felt like I was fucking a.
