This hilarious duel pump action penis game is like nothing else you've seen and the perfect party piece for bachelor and bachelorette parties and other fun-filled events. How to play: Before you begin, pour liquid into the hole positioned between the two shafts. We advise water but any safe to consume liquid can be used. The object of the game is to pump the penises as quickly as possible to be the first player to squirt their opponent in the face, or mouth, and be declared the fastest wanker. Then, pass it on to the next contenders.
