It's not happened to me. Until recently I never considered it a possibility. Thanks to a certain someone on here my mind is a bit more open to it

Few years ago I had a Mistress who desperately wanted to do this to me even though it was on my hard limit list. Especially since i am a bit of a germ a phobe. Later she explained to me that since I am such a kinky bastard it was a turn on for her to push me past one of my hard limits and she surmised that it was the most attainable. Long story short after a night of drinking I agreed to it and even cleaned her pussy afterwards resulting in a very powerful orgasm for her. And of course making my Mistress happy only fueled my own great orgasm. The concession I made with myself was that at that point it was more rented beer than bodily waste.
