This isn't bad, but if you hate NTR, you should leave. Even though it's kind of not. I'm just here for the thiccness, not the plot. You should go read his other works. (Okusan is amazing!!!)
Is hitting people even a fetish? I mean, like beating them bloody with your fists. Unless your partner is a huge M, (and asks you to) I don't think beating the shit out of someone during
sex is ok.
