The silver lining of this whole situation with the mom being defiled by her douche boss is that this little shitstain of a friend of MC gets his comeuppance for the "watch me assert my superiority over you" stunt he pulled earlier in the story by doing something as disgusting as embarrassing a mother to her own child in the worst way possible.
Eat shit fucker lol, now that same "masculine superiority cuz I've sexually conquered a woman" is the reason why your partner got stolen away from you by another man. Live by the dick, get NTR'd by the dick lol.
