Where the main character was kidnapped when he was a child and raped in a warehouse or someplace, and the kidnappers all ended up dying. He was rescued by his father, (who then would have sex with him) and it turned out he wasn't his father.
Some demon-type guy appeared and became his bodyguard or something and the main character always wanted sex from him, but he wouldn't allow it and so he had sex with succubi.
I may be getting a few details wrong, I read it a long time ago.

Any help would be appreciated. Thank you.
