The ol' snake convention
A standing 69, when the male is in a handstand with a maraca handle in his butt, imitating a rattlesnake. Simultaneously, with a caprisun/juice box in her mouth squeezing the juices out on the male as if it were venom, simultaneously, as she climaxes.
Down in the desert, where the coyotes howl and the ladies thighs shake, like they have two tickets to the ol' snake convention.
