Hey Everyone,

My laptop died suddenly, so I lost all my bookmarks. I've re-id'd some things but there's this one I'm having super issues finding - that I really really want to read again. I think it's because it's from an anthology. I'm fairly sure but not completely positive, on this.

Specifically, the story I'm after has a salaryman M who kidnaps a highschool (maybe) thug/streetfighter S.
The salaryman loves the thug but thinks he's a normal boy so does nothing, but when he sees him fighting and how he gets off on it, he decides to seek him as his master. But he does this by handcuffing/locking him up for a few days and then revealing his needs. Even while handcuffed he tells the man to beg and mentions how the bruises shouldn't be visible when in a suit because his coworkers won't understand that he loves it.

a random point is that
The thugs sister is interested in the salaryman, that's how he the know each other.
The salaryman wore glasses, I feel like I remember a panel around the very end where he's taking them off (for the beating maybe?)
I think the M had short dark hair and the S had scruffy light hair, but am in no way confident about this design.

I've been through the first 3 pages of these types of requests and didn't see anything even slightly resembling this. 270 pages is a lot to go check, so If this has already been mentioned somewhere hopefully it can be restated here.
