One in the mouth and one down south

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.

flushin' one down 

on your period; menstruating.

derives from the fact that when you are menstruating, the blood is a conduit for the expelled egg, which will no longer be able to become a child. When it hits the toilet, you flush it down.

Geez, MaryJane, why can't we can't have sex just 'cause you're flushin' one down? I was really hoping to get my red wings tonight.
