So I'm looking for this hardcore NTR yaoi that I have read a long time ago (in some language that is not english.) It has a school setting. There's a couple (I think, cant understand) but the uke got molested and raped (again, I think) by this guy, who has a harem of ukes serving him. He mind-broke the uke and the uke tricked (again, I think) his bf so that the guy fck his bf too. In the end, both of them submitted to the guy...
