Watching her fuck is not enough
This guy wants to live large, but with his job skills he might as well become a pimp. What a great idea! His girlfriend is a slut who loves fucking total strangers and with a pussy like hers he can get reach in no time. He hooks his bitch up with some rich dude who always wanted to fuck her and watching her get fingered and drilled from every direction makes him so jealous and horny he eventually ends up joining the fun to get his cock sucked too.
