I'm tired of broke cheap clients begging for a discount. So I offer a 'Five Finger Discount' to my next customer. He gets tied down, thinking it's going to be a nice long handjob.. But he's about to find out what the discount means. I slap his dick repeatedly, and vent my frustrations on clients like him.. All the way up until he cums, when I take away any pleasure by ruining him while slapping his cock.
