...I think it was either part of a series of oneshots or not the main couple of the manga. I can only remember this one scene where i think the uke was sleeping next to the seme and the seme has a dialog along the line of how a good boy the uke. Showing other panels with parts of bodies of probably other boys in bondage kind of thing.
...not completely sure about the details because it has been a long time since I last read it.

Sorry for lack of information!
