In a world oppressed by an evil dragon king, Glory is a promising man training to become a hero who could kill the dragon and save the world. He finally manages to obtain the magical sword that has the potential to increase his attack stat high enough to kill the dragon.

The catch? The sword will increase his Attack value every time he cums with his ass at the expense of his Intelligence value. In other words, if he can find someone to literally fuck his brains out, he’ll get enough power to save the world. So he finds a pair of incubi to do the deed. Except, he underestimated the effect of lowering his own INT will have on him. If he’s not careful, the incubus pair might just turn him into a dumb masochistic slut.
