The active player picks an action from the list and tells the other player what they have picked. The other player picks a body part from the list and doesn't tell the other player. The active player has three attempts to guess the body part by performing the action on the parts they guess. If the active player guesses correctly they swap places becoming the passive player.
Example: If the active player picks bite. they might bite their partners neck. The passive player tells them they chose wrong. The active player then bites a nipple. No thats not it either. Then nibbles on an ear... oooh thats it.
nuzzle/rub face on
dance/rub groin on
The active player seems to be in the most powerful position because they get to pick not only what action they want to perform but they can choose 3 different body parts to perform the action on but it's
The passive player who has ultimate power because they can lie.
If the active player guessed correctly they can still bluff and
tell them they failed to make them go another round as the
active player or they can lie and say they guessed right if they want to be the active one.
