i assume its one of those NTR were the boyfriend is in on it to an extent. like the ones were the girl has sex with other guys but says she still loves her main guy but in this case the main guy is aware of the situation and knows that the girl is such a slut that he A: cant physically satisfy her himself or B: he cant fulfill her fetish even if he's decent at sex.
