Misuzu, a slender beauty with beautiful breasts, is a teacher who teaches brush pen to people in the neighborhood. Although she is usually kind, she also has a cheeky and arrogant side. One day, some regulars come to learn brush pen, but as they play various pranks on her, Misuzu gradually becomes angrier. The regulars give her a gift to calm her down, but it turns out to be an aphrodisiac... Her body becomes hot from the core, so she sends the regulars home to take a shower, but her body becomes more sensitive. Unable to hold back, she masturbates, and her pussy juice becomes milky white. When the regulars return, Misuzu has transformed into an erotic slut mode!
