Bitchincho ~Zen'in Seiretsu. Tou Class no Ochi×po wa Watashi Koto Iinchou ga Ikkatsu Kanri Itashimasu~

Synopsis

There's a school called Bichi Gakuen where students learn all about various sexual activities, techniques, and practices - foreplay, afterplay, and every kind of intercourse you can imagine. The game is basically an idiotic nukige where all characters have a 0% virginity rate. The female committee members are the only girls in their classes, and they're all about getting down and dirty with the 20 boys in each class. And they're loving every minute of it!
