I take a peek in booth, it is empty, and I remember the door rattle, so this time, I DON'T LOCK IT. I pop in some tokens, and here the door. A middle ...ged 40ish father of two comes walking in.....lol, I don't know for a fact, but that is what he reminded me of. He sit's down next to me, and doesn't say anything, just pulls out his dick and starts watching porn and playing with himself. Im feeling a little awkward until he does reach over and put his hand on my knee. He is rubbing my nylon. Alongside them I was surprised to see Sammy and Emma kissing and fondling each other, Sammy had managed to free one of Emma’s boobs and was sucking on it wantonly – Emma with her head thrown back obviously enjoying the sensation.I took a seat opposite, content to just watch the action, although I could feel my cock stiffening already. I had my back to the stairs and thought I heard someone descending them just before hands were clamped over my eyes “Guess who” a female voice whispered in my ear. I got a thrill seeing the woman making the youngster bob over a man’s erection. Doing such a shocking act alone was one thing; having a woman watch you do it was something else entirely. There was something exciting about being exposed. I was too shocked to move; too fascinated to look away. Mr. Cooper pointed at the screen, saying, "That's what that guy outside wanted you to do on him, to suck his prick like that lady. Now do you understand?"I turned to him and said casually, "Oh, I get. Our friend could not stand it any longer and he quickly took off his clothes. When he got down to his underwear, I could see a dark wet stain in front. As I moved back and forth onto my husband’s cock, I asked the guy to show me his dock. He doubted and I insisted whispering softly.Then I could see his long, thick cock twitching at being freed.He knelt beside us, watching us, as he stroked himself. I reached over and began stroking his hard cock. He was clean shaven. Then I pulled on his balls.
