Illicit Relationship. Its on Webnovel. It's pretty bad though. The story, the writing style, and the smut is crap. Honestly, it feels like it was written by a fourteen year old. There's Profane Prince of Domination. The mc mom is part of his huge harem. Dragon Blood Warrior. To be honest, I read that for the smut so I don't remember anything else but the smut. And it's crap because of the censorship. Road to Kingdom. Doesn't have what you want but MC is a MILF lover.
