Who's in my mouth

a sexual game played with 5 or more people. rules of the game are that everyone must not talk and turn the lights off. once that is done have everyone undress and start putting,their genitalia in each others mouths and have them guess who is in their mouth. no one can talk except for the person with the genitalia in their mouth. if the person guesses correctly then they get to go again. so on and so on until they lose. randomly select the next person to go.

*random person sticks he nuts into mouth of selected person.*
selected person: ughh its soo hairy.umm i dont know Who's in my mouth. come on tell me!
*muffled voice due to genitalia in mouth*
