Students gather at the nurse's office after school. Naked, the students form a line and, like cattle, take turns wringing out their semen. Using a dick sleeve to jack off, they come in the blink of an eye. Minori, who, as usual, has a high semen output, was able to collect money more quickly than everybody else. However, she grew completely addicted to the effectiveness of the dick sleeve and ended up earning money for more of them instead.However, the vibrator Minori wanted costs tens of thousands of yen. She simply could not cover its cost with pocket change. When she had a conversation with the school nurse, she chanced upon an introduction to a great part-time job. It appeared that the nurse recently developed a taste for semen baths, and she was willing to pay 1000 yen for each bucket of semen. Of course, Minori jumped at the proposition.
