[ie] Demon King's Omake Nakadashi Manga

A hero storms the Demon King's castle expecting a final battle, only to be offered half the world—or all of her. The curvy demon girl with horns, wings, and a tail bares her big breasts and asks him to be her husband, and once the hero lets his desires take over, she rides his sword with such tremendous power that he can barely get a word in. Between RPG-style menus asking whether he'd like to finish inside and a triumphant 'I defeated the Demon King!', the clash ends in a messy impregnation and an epilogue of wedded bliss with his pregnant demon bride as peace returns to the world.
