Each ridge is a powerful vibration point. XXX The machine is also equipped with a vibrator, which rests against her clit. The girls must move forward while trying to avoid the random upthrusting of the dildos. The pit is also partially filled with artificial slime. BASIC PREMISE
As contestant advances, women will eventually lose their bikinis, have to ride various mechanical fucking machines and at the end stages involve large quantities of sterile artificial movie special effects slime, dildos and wrestling with each other. The pit is also partially filled with artificial slime. Bikinis can only be tied with a standard shoestring tie
If any part of the bikini comes off during the game it must remain off
If any part of the bikini becomes dislodged, it must be removed
THE PHALLUS BENCH
The women straddle and slide along a long gigantic padded gymnastics balance beam shaped like a giant phallus, from balls to end.
