Kyonyuu Dosukebe Gakuen ~Shojo-tachi no Tomaranai Koshizukai~

At the protagonist's school, there's a notorious club of girls who allegedly bully men into submission through sex, leaving them like empty husks before moving on. Rumors say they've each had over 200 partners. One day on the train, the protagonist overhears a shocking conversation: these girls are actually all virgins. Unluckily (or luckily) for him, he's caught eavesdropping. That's the day they decide to silence him by finally living up to their legend—targeting him as their very first victim.
