CHOCOLATE SUPERMAN
very similar to the original superman except instead of cum smeared on the girls back it's done with feces (your own or somebody else's it doesn't matter). Feces must be the right consistency not too liquid and not too solid. also the feces must be fresh (very important.
your girl is asleep and you smear some feces on each shoulder blade then stick a bedsheet to her back so when she wakes up she's a chocolate superman.
