Another form of gangbang, in which three or more men have sex with a woman. In the case of a three, one man would have his penis in her mouth, one would be in her vagina, another in her ass. In a five-to-one, she would also have a penis in each of her hands. A six-to-one would encompass her also being titty fucked, or with more than one penis in her mouth.
So yeah, my buddies and I found this chick last night. Man we totally had a three-to-one with her.
