Rape story. Not trying to normalize but well....

Demon. Full moon. Incest. Victim blaming.

In the phase of the full moon, Rin is on the verge of lust and going berserk so he, requests Yukio to kill him if anything bad happens. But Yukio didn't want to so he forced himself to mate with rin in the state 'i'll help u, brother'.

"You're my demon so it's my job to tame you"

"aah my head, I'm getting dizzy, I can't take it anymore, It feels too good."

That's it :)

Devilish uke. Riding. Blackmail. Punishment game. Kind of non-con (but they're horny). The ex was an asshole!.

The main point is quite plain, I mean it's a punishment game! a lot of yaoi story comes with it. But for this one, the author makes it so interesting. I love the uke personality, the devilish dom-like uke. It's so different from major jinx back then where usually the seme who was the one who blackmailed the uke.
