When a guy is having anal relations with a girl and pulls out of her bumbum and has poo on his dick, then flips the chick over and uses the poo as lube for vaginal intercourse.

Every girl loves it, a lot.
"Hey man, did you earn your poo dick last night?"
"Yeah dude, and I was a Poop Luber too."

This might be the nastiest fucking thing I ever wrote....
