I know where you're going with this, so let me stop you right there. She is not in the best position to decide what is best for herself because she is DESPERATE. Her rationality has been compromised, clearly, because a person with their free will still intact would not opt to have sex with someone they would otherwise not wish to.
So what we have to ask is this: is she making the best decision? Should she instead pick eviction (or continue paying, but I assume she is unable)? If we can objectively say that it is better for her (and her brother) to be evicted than to have sex with this guy, then we can say that he is doing something both morally and legally wrong.
However, if we objectively say that it's better for her to have sex a few times a month rather than make herself and her brother homeless, then he is doing her a (although small and still perverted) service.
Internet is amazing, we can almost post every drama movie scenarios and tell it happened to somebody we know...
So... the girl don't have any family, uncles, aunts, grand-parents, dogs, nothing... And she is forced to sleep with your ugly 300 pound brother to be able to feed her 11 years old brother.
I would buy this movie, for sure. (the girl needs to be cute tho)
It's actually Illegal to do this. I silently sometimes wonder what MMO Champion stance is when people report on illegal activities. This thread is pretty much saying he's "made her sleep with him" is illegal as trading sex for money is a felony in the United States. (Unless of course Vegas) this sounds like a young vulnerable girl being exploited by an older man and I just find it disgusting that it has not been addressed.
I remember this thread from weeks ago..I seriously doubt he's "making her." It sounds to me like she accepts the trade off. If it was really that bad she wouldn't allow it to happen. If it really is that bad, and she allows it to happen, it's just as much her fault as it is his.
"Taking advantage of" is a whole different story.
Your brother kinda sounds like a scumbag. Poor girl.
Prey on the weak and you will survive, prey on the strong and you will live.
