I'm looking a short yaoi I think where the uke was probably either a rent boy/prostitute or a fuck buddy, and the seme ends up having a shrine of him, they've been together for quite awhile I think, it was pretty kinky if I remember haha
i think it's Hentai Shinshi to Kisekae Dansho, here's the link:

As a passing thought I sometimes wonder if they think stopping midway thru forcing their partner makes them less horrible hahahaha
No ill intent tho just pops up my head as a question sometimes (ㆁωㆁ)
