One partner hangs upside down from a high place, while the other partner runs around the room and beats their chest while shrieking at the top of their lungs. Once out of breath the hanging partner must fall down on top of the other partner's back and they must wrestle to figure out who is the dominant one.
"Hey fellas, see that girl over there? She is into all kinda of weird stuff, even upside down monkey sex!"

Get the upside down monkey sex mug.
Usually reserved as a "finishing move" during heterosexual intercourse. While the male and female engaged in Missionary Position intercourse the female lowers and closes her legs and the male then straddles her thighs an continues to thrust, making more contact with her tightened vaginal canal and clitoris thus increasing both the chance of and intensity of the female's orgasm. A secondary benefit is if the male is going to "pull out" he is in the perfect position to dump his load all over her stomach and breasts.
Frank and Renee were reaching the point of no return when she moved to Legs Down Sex so she could cum hard and fast before jacking Frank's crank all over her tits.

when your friend is tired of his girlfriend, having sex, he passes her down to their friend in order to fulfill his needs, because he's tired of wearing her on his cock...
