I'm not sure if this is what you're looking for, but read chapter 6 and 7 of this: http://www.mangago.zone/read-manga/drugless_sex/ and then a one page extra: http://www.mangago.zone/read-manga/drugless_sex/uu/mpn_chapter-1980774/pg-10/
Ik this is pretty fucked up (as it is), but does anyone know any manga/manhwa with this power dynamic, or where the seme is older but has ties with the uke from say childhood or early adolescence and then the story progresses from there?
Kinda like how Uncle guy progresses slowly with Haruko from like sleeping with him(like literally beside him) to jerking him off, to actually fucking him. Like maybe a transition instead of Uke meets Seme, they fuck immediately kinda thing, ya know?!
