This game is cruel but very simple! Fill 2 gorgeous girls up with fluids until they are desperate to pee. Present them with a jug containing a series of printed tasks, one of which gives them permission to pee. The rest have them perform differing tasks, none of which are very pleasant; jump up and down, have your bladder pushed on, expose your pussy, lick the other girl's pussy, remove items of clothing, show us your butt hole, you get the idea! Hopefully, eventually, desperately they get the "you can pee" card and pee they do! Gallons!
