When he was a freshman his teammates turned him out and made him a cum dump.  As a rookie he was getting fucked by dozens of guys on the team on a daily basis.  He got used to it and now his ass feels empty if he is not fed cock on a regular basis.

So during the day he is your average college student and jock.  But at night and on weekends he is a whore, going downtown and selling his ass.  He is cute and young, so he could charge a lot, however he is usually so horny and just wants dick, so he averages five dollars a fuck.  Which by definition makes him a cheap whore.
