When two males and a female participate in the act of copulation and one male's genitalia are in the mouth of the female and the other's genitalia are in either her buttocks or her vagina.
My friend and I wanted to have a threesome with a female from the workplace except we weren't comfortable with textbook double penetration so we decided to put one in the mouth and one down south.
