Get this... creepy

It's possible to pull off a polygamous relationship unit, but success is vanishingly rare. Usually the only onse who can do it are extremely ugly and undesirable people - basically they're sluts but can't get any play from anyone else.

A couple who engages in no-strings-attached sex with outside parties is far more common and not in and of itself a sign of brokenness. But hell, I wouldn't do it either if I was the threadmaker. She's propositioning a dude, which means the boyfriend is at least okay with naked men, which means there's a good chance the balls will touch at one point. And you all know what that means.

Jam it back in, in the dark.
