Naughty games, especially if they are funny, are always welcomed by customers.

The rule is very simple. Fill the base with water or another edible liquid.
Once filled, the principle is to masturbate the two rods present as quickly as possible until "ejaculation". Whoever masturbates faster will cause this "facial ejaculation" to his opponent.
A moment of laughter will fill the room and the loser will have to give up his place to the next player (or players).
