Aibu Kettou de Gakuen Musou!

Haruyumi Fukamino transferred to a private school, Amagasawa Gakuen, with a unique educational philosophy where "caressing practice" is emphasized.

If the private parts does not become moistened, there won't be any pleasure. If there is no pleasure, there is no reproduction.

Haruyumi is both delighted and dismayed to learn what this means, when he meets his first training opponent, Mizusa Izuma, a silver-haired, dark-skinned gal who is respected throughout the school as "The Handjob Goddess."

Haruyumi has never anything to do with girls in his life, but thanks to a special pair of eyeglasses he received from a mysterious man, he easily wins. The romantic comedy begins with him relying on the glasses and his willpower to make her cum all over the place…!

"The only thing you should say is "I'm sorry," to apologize to all the boys you've dominated up until now…"
