"This is so fucking weird"?
Well hey, it's Hentai, so get used to it.
I am, however, slightly disappointed in that ending. He should have grabbed her, pulled her back in and then become her new boyfriend.
And then they can proceed to have more sex.
Actually this guy should run after her, grab her and NEVER ever let her go. Compality is there. The girl is hot. The guy would only gain. Heck he even got money to have sex with such beauty.
Even for being hentai, this is too unrealistic. Anyway, awesome read.
I wouldn't say this is more unrealistic than a girl being raped and abused by guys starts to enjoy it halway through which is a pretty common hentai scenario...
