Attached to her challenger via a exercising resistance band around their thighs, both on all fours in a crawling position with their butts at the ready. They both wear matching bikinis and Nylons to take part in this butt-off! The aim of the game is to smash the oppositions egg first, using just the butt... There are variety of eggs, some hollow and others (halved) and filled with slime and custard!
