START-586V — [Bonus Edition] Homeroom Teacher: "Starting today, I'm appointing Shinkawa to be on sex duty. If you don't fill the beaker with sperm in one week, you'll be expelled, so do your best." Shinkawa Sora

Sora-chan has been appointed "sex duty" by her homeroom teacher because she hasn't contributed enough to the class. She's told that if she doesn't fill a beaker with sperm in a week, she'll be expelled, so she diligently works to collect semen. At first, she was embarrassed about the duty, but if it helps improve the boys' grades, she'll do her best!
