After getting requested by her first customer, she nervously goes to the hotel... and finds out it's a super-extravagant first-class hotel suite! And then, a super hot guy appears. When she asks him what he wants, he says: "vibrator, electric massager, money shot, piss play, and masturbation viewing," then hands her a wad of bills... just who is this hot guy?!
