Looking for a yaoi where a student uke lives in a seme teacher's house for some reason. With light bdsm(?), I remember a scene where the teacher cut open the pants of the student in his house, they also used a vibrator if not mistaken. There seemed to be quite a large age gap as well...
I think it's this one...

My only guess is ML is a cop "working" at the club as a "customer" and had to hide from MC and that makes him an important character to the boss of the club that came to stop Taeso? but man if he does turn out to be a cop I'll be so disappointed cus thats shits just lame.
