Maybe it's like an old friend came in from out of town. The couple who owns the house hasn't seen her in forever. They *both* have a sexual history with her but neither knew that about the other before tonight (we've all go secrets, right?). One thing leads to another and after a few (or more) drinks their guest slips up and mentions how she still misses the way he kisses. Yada yada, everyone's horned up and we got ourselves a sex selfie. Maybe? Let's keep thinking about it.
