The Demon Lord just needs a good ORGASM?!

"It was about the time I was pinching a fox-girl’s nipples in order to kill a minotaur that I realized how very weird my life had become." I was just like you—living a totally normal, loner weeb life—until I got transported into this weird harem world, where I'm needed for my magical powers of perversion?! And now I have to help stop the terrible Demon Lord who's been rampaging around the kingdom for a decade because she can't have a decent orgasm?! Seriously, what the hell's wrong with this world?!
