Wife unknowingly put on a show
I can't help it but I like to have other men watch my wife either naked or in the sex act with me. One time I left the blinds closed but about 2 inches above the window sill and cracked open the window several inches. There were some young guy hanging out several feet away from my window. I knew they were their so I called out to my wife in the next room to come in and lets have sex, loud enough to be heard, I was sure, by them.
Sure enough they started peeking. Wife had no idea and I told her to get naked and shake those tits. I had her blow me, on her knees, then I fucked her in several positions. She always has loud organisms and I would sneak looks to see those guys reactions; their reactions made me even harder. I imagine those young guys jerking off and telling their friends, and that gets me hard without fail.
