So I was shagging these chicks (stinkies in one, and cock in the other), and I realised mid-thrust that they looked almost identical. I exclaimed on the apparent doppelgängbänger scenario, but it turned out they were just twins.
You know, when a bunch of people that look kinda the same have sex with some other person. If they're siblings, it is not doppelgangbanging, it is incest.
Alec Baldwin, Tom Hanks, Mel Gibson, Richard Gere, and Al Pacino are all having doppelgangbang with that one girl.
