Fondue Blumpkin

This is probably the apex of sexuality. It's when you have bad diarrhea while a female (or male I suppose if you are inclined) is giving you a blowjob and you remove your penis from his/her mouth and dip it into the chocolate toilet soup only to pull it back up and reinsert within her/his eager mouth for an extra saucy reentry. Pretty much a dream come true.
