18+ Saikyou no Haramase Onaho Kishidan: Kyokon ni Katenai Mesu-tachi no Zettai Chuusei Harem!

Fantasy reincarnation! The harem king of a bevy of sexy knights. He was a virgin until death. Reborn as the son of a wealthy family in a parallel world, he at first seemed doomed to repeat history, living the life of a sexless NEET. Money is no concern to him, but reincarnation should be more fun than this!. He takes the wheel of fate and makes a hard hentai turn. He's surrounded by beautiful chivalrous lady knights. He'll create a harem! Faces will gape. Hips will quiver. He's royalty now and will enjoy it!
