anger and humiliation

You can see anger in the jock's face, but also hints of resignation and humiliation. You keep fucking his girlfriend up the ass until you cum. You then pull out and have her suck your dick clean. "For the rest of the day, go out and bring men back here to fuck in front of this asshole. Have them fuck your mouth and cum on your face, fuck you doggie style, titty fuck them, and give them hand jobs until they cum on your face. Do this until you've fucked 10 guys or the store closes. Got it?"

The exhausted girl nods. You look at her jock boyfriend. You know he wants to kick your ass, but he can't do anything about it. "Watching your girlfriend fucked by other guys makes you horny; in fact, it's the only thing that'll make you horny for the next six months. Enjoy!"

The jock's eyes go wide. He's hogtied, so you know his dick is getting hard beneath him and being pressed against the floor has to be painful.
