Only slightly more complex than Spin The Bottle, it is by far more intimate than Twister, and has a much bigger payoff than Monopoly - it's Erotica! Accompanied by one or more adults, you roll the dice and move your game piece around the board, following the instructions where you land.
Do you slow dance with or french kiss another player? Maybe you strip an article of clothing? Roll again, and pay a visit to one of the houses of bondage, servitude or corrections; you could find yourself performing any act from a simple back massage to masturbating fully nude in front of the other players while bound, gagged and blindfolded - blank cards allow players to use their imagination.
If a given task seems too extreme, you can save your ass - but it could cost you later, when the winner makes servants of the other players for the remainder of the evening!
