The Growth Game

3 friends are playing a magically cursed board game, where every turn they take will alter their body in some way. They initially don't know that the board game is magic, but quickly find out as their bodies change after their turns. The Game initially starts out as fun amongst friends, but quickly turns erotic and sexual once their bodies become more and more transformed. They cannot leave the room once the game has started, they are magically locked in, the game has to be finished. The players get progressively more flustered as their bodies morph to become more sexualised
