An advanced sex position involving 2 men and a
female participant. It is accomplished by the
female being in a kneeling or standing position, with her one of male partners penetrating her from the
front, and the other from the back. While engaged, the male partners vigorously insert sex toys (usually some variation of a dildo) into the opposite male partner's anal cavity. This position is known for its intense prostate pleasure, and high level of skill involved.
