Possibly the most degrading thing happened to me last night. I finally mustered up the courage to confront my wife's lover while he was about to make love to my wife. After a bit of a struggle I was eventually overpowered. He took the opportunity to place his naked ass squarely on my face while he proceeded to screw my wife. As his ass pounded my face, he finally placed his anus over my mouth. For some inexplicable reason, having given up all my resistance, I sealed my mouth around his anus. He then defecated strongly in my mouth (he was still screwing my wife at this stage). I found myself swallowing every morsel and even licking his anus clean afterwards. What absolutely amazed me was how this made me feel. I had the most throbbing erection I have ever had. I continued to plant passionate kisses on his anus and eventually I came uncontrollably. Both my wife and her lover burst out loving at this pathetic display. Her lover then started to wriggle on my face and tell me that I would be his ass slave for the rest of my life. I am filled with a sense of self loathing but utter excitement at the same time. I am not gay but can anyone explain these feelings?
