[Zettaizetumei no Yamagoya (Zettaizetumei)] A Bratty Little Demon and Her Cherryboy Teacher [2d-market.com] [Decensored]

A bratty little oni girl with horns and a wicked grin turns the tables on her glasses-wearing virgin teacher, pinning him down with her foot and stripping him bare before teasing his throbbing cock without mercy. But she has more in store than mere punishment—her horns carry the Curse of Matrimony, a binding spell that ties him to her until death do them part, and she wastes no time sealing his fate. What starts as a brat's power trip spirals into a supernatural claim neither of them can undo.
