Once in a while, my wife/mistress has a hot surprise during one of our intense sessions. Having connections in her female dominant circles, she occasionally comes across a hung Shemale willing to fuck my ass while she watches. Whipping me into a frenzy, she renders me unable to move tying me in a very vulnerable position, doggy style. Her phone rings, and she tells her friend that it’s time. She loves, watching me take on those big cocks from those beautiful she males. She knows that I’m totally straight and would not bend over unless tied, which definitely turns her on all the more.
