This guy is getting his meat where he makes his bread, right there at work. He would be nothing less than heroic if he charged her for the massage after blowing an enormous load on her.
Him "That'll be fifty bucks yo"
Her"Don't I at least get a discount ?"
Him "Got a coupon?"
Her "Fuck you"
Him "Hey I provided you with a valuable service you little slut"
I'd keep an eye on my car in the parking lot for the next few days.
