as others have said, who cares at all whether she is enjoying this or not. she exists here solely as a collection of moist holes for him to use and fill and pump however he pleases. it looks like he's having a great time fucking her tight body, so good on him! she's doing her job well, and he's utilizing her nicely
Who cares if she's "not enjoying it" or whatever, she's a whore. It's not supposed to be fun for her. She just takes it for the cash, I'd hurt her too.
