The only title I can think of off the top of my head is "Metropolitan Nepenthes".
Seke partially counts, partially.
You’re right, I think it’s quite rare! I could only think of these two examples, second couple in both stories:

I just remembered At the End of Death also counts https://www.mangago.zone/read-manga/at_the_end_of_death/
I actually have a hard time getting into dom/sub universe work unless the Dom is the uke, so far I can only find https://www.mangago.zone/read-manga/good_work_watase_san/ (in which the dom later becomes a switch) and chapter 2 of https://www.mangago.zone/read-manga/dom_sub_universe_bl/
Any recommendations?
Maybe this one?

not exactly dom/sub verse, that's just omegaverse, but appreciate the share.

Of what I know there aren't other subverses with those specifics in mangago ╥﹏╥
If you want more dom/subverses works here is a list https://www.mangago.zone/home/mangalist/1738454/
