Liz and Charlotte Mystery Envelopes [GungeTank]

Today Liz and i are wearing two very slim sexy black dresses with no tights. We flip a coin to choose who's going first. We have a table of envelopes, one of us sits in the gunge tank while the other chooses a envelope, the chosen envelope decides the fate of the person sat in the tank. The tank is full of bright green gunge. and the looser that gets gunge takes off her shoes and is bare foot in the gunge.
