Why is everyone thinking that he's making her a sex slave? The guy gives her protection, food, acomodation, etc. And in exchange, she fulfills his desire (which she doesn't mind, heck even she's the one coming to him). Is that what you call a sex slave? Sex slave is more morbid than that bruh chill out.
Stop getting tilted about this. No girl is going to look at your comment and say "Wow this guy really respect women".
