threesome with two guys and a girl
guy in the middle fucks the girl while being fucked by the other guy;
so you have three flavors: a straight person, a bisexual person, and a gay person
corresponding to the 3 flavors: vanilla, strawberry, chocolate
Guy: Yeah, me, Bob, and Anne got wasted
last weekend and had a Neapolitan.
Other guy: Who was strawberry?
