Alright, so I found some weird game. It sounds pretty disgusting, so discuss it!
"Get some friends to form a round in some place with a small table in the center of you guys. The table has to have a big cookie on it.
Next, each and every one of you strip your thong, and reveal your sausages. You take your right hand (left hand if you're trying "hand change" or in case your a lefty) and all of you at the same time start fapping.
Each guy must be concentrating on his own fap, and concentrating enough to aim for the cookie. If your sperm landed on the cookie your safe, but that who shot out cum and it missed the cookie suffers great consequences.
He eats the cookie full of sperm from those who didn't miss. And if he refuses to eat the milky cookie, you basically beat him until he accepts to eat it."
