Graydaze's manga / #Possessive Lover(66)

Uke stalked popular guy, he's actually a psychopath and a killer in a yakuza type family. Uke is sweet and innocent and seme rapes him and forces him to keep coming back. Uke can't do anything without seme's permission or he gets punished, and seme's punishment is violent. Don't see how this could possibly have an ending I'd actually like, but the story and art are good.
