Looking for a yaoi
The uke and his older brother(the brother is a doctor and probably their dad was one too) have sex regularly (but its not love) but the uke meets the main seme and idk if they start going out or if they have sex but the uke tries to stop doing it with his big bro but the big bro aint going to let it go too easy. I think the seme learns about the big bro doing that and will try to threaten him to stop (if people find out about big bro its dead and his reputation is important as a doctor and i think he is supposed to inherit the dad's hospital or something) i also remember when the big bro and uke having sex, the big bro use a sex toy, the one where you put a stick in the uretra (OMG WHY STOP THIS) ps : please dont put stuff in the penis's hole
