5 round revolver
When 5 people fuck one person in the ass and then draw straws and whoever loses has the cum and possible shit farted back into their face.
Hey me and 4 other dudes had a gang Bang with this person and we made it interesting we drew straws and the loser had to have all the jizz shot back into their face. Man I'm not sure I ever want to have a 5 round revolver again.
