Substitute
My wife has always wanted to be fucked by someone while I watched. Well she got just what she wanted, but not by Mr. Cool. I told her I had someone in mind but that he didn't want her to know who it was. so she agreed to be blindfolded. The fun thing for me is that I had a friend that I knew from way back in JR High come over and that guy she despised as way lower on the scale of humanity than my Prom Queen wife. There she was tied up naked when he walked in, her vagina and anus right out there in full view. She was excited I could tell that and so Arnold got to play with her as and tits while she wiggled with excitement. And me, I just watched something happening that she would never ever imagined Arnold fucking her with a big smile on his face, getting to hear the woman of his dreams make her little squealing sounds, doing her orgasm thing for him, and she never knew.
That is fucking awesome. I can't tell you how many "prom queen" and "cheerleader" types from high school that I would LOVE to do this to. Give 'em all what their prick-teasing little cunts deserve.
