The only girls' school in Japan where you can learn sex techniques during class! Four schoolgirls led by Rumika are studying every day to become top sex workers! They take thick semen in their mouths during self-study at a pink salon, let their momentum take over during real insertions during self-study at an image club, and squirt during self-study at a soapland. The final exam is an 8P orgy with the aim of passing!
