(N.) An incestuous game in which participants attempt to have anal sex with family members while blindfolded. They must come as close to orgasm as possible before moving on to the next family member in an attempt to make it through all participants without ejaculating until they have reached the last participant. A non-family member will frequently mediate the movement of people and ensure that all blindfolds are on.
