Women only do this with extremely good looking chads. The average man doesn't have this happen for him, the most he can get is fucking another woman while his girlfriend absentmindedly watches. They don't get all happy and start making out and stuff unless they're with chad, their womanbrains start going "we're being sexed by chaaad, I'm so happy excited about chad that I want to kiss you too". They don't get like that for normal men, even during (likely soullessly pre-planned) threesomes.
