Taking a #2 on someone's chest

I don't know why or what sick ass clown ever thought of taking a shit on someones chest during sex.  What asshole introduced that A, and B, who said "Let's do it, shit all over me please" Imagine being a fly on the wall in that room " Alright honey, lay on your back as I squat over you and make magic happen, (uncomfortable pause then a...GRUNT) ahhhhhh". I don't know about you, but if a person were to shit on my chest, the party is over and I'm rethinking my life choices right then and there, with dook still on my chest of course. The question is not only why, but we also have to look at the how factor. If a girl specifically asked for my doo doo and I was copped over her, I would still be hella leery, I know what my asshole looks like and I dont want anyone to ever see it, I guess I have an asshole complex. Maybe if you threw me a newspaper and a smoke, I would be more comfortable, but even then. Going ATM(Ass To Mouth) is another issue. I could never kiss my girl after I put it in her butt and she blew me.  I mean, a stink palm is one thing, but a stank mouth is a whole different party. All in all, I guess im old fashioned, a serious deep dicking in a woman's vagina is the route I take everytime, ass play is a detour I stray from.
