I know a guy through a guy, who got cheated on. He took his wife afterwords and tied her up like he was going to get kinky.... (she didnt know he knew yet)
Really he tied her up and said "You shit on me, now im going to leave you with the same feeling" Pulled down his pants, hovered his ass above her face, and took a big nasty shit right on it, then left her there tied up, with no way of calling for help.
I personally think that's a beautiful story. Justly done! I probably would have executed it a little more extreme, but thats just me.
