Whacky Shack 

A game where you and your buddies go into a room with a blanket for each of you. The next step is to turn the light off and all of you have to strip naked. Then, all of you start wanking off, but someone has to be sneaky and turn the light on. If you notice them, don’t confront him, pull the blanket over you. If someone sees your peen, you’re out. Last one wanking wins.

I went to the Whacky Shack with 9 friends.
I lubed my dick with my own shit in the Whacky Shack.
