I'm looking for this manga and it's a dom sub scenario. I remember one of the first scenes being that the dom made the sub do an enema. There's chapters where the dom is whipping the sub and ones where the sub is tied up to a long chair and plugged up (?) I know this is really generic....would really appreciate any help at all!! ლ(´ڡ`ლ)

I believe the first chapter was about this man who was obsessed with a certain female porn actress and somehow ended up fucking this other guy in a washroom who turned out to have the same name as the female porn actress (Chihiro I think..?) (⊙…⊙ )
