Megumi is a health and physical education teacher at Kameda Gakuen. Her charming points are her friendly smile and her super busty figure that seems to have jumped out of a manga! Megumi-sensei cares about her students, but her teaching always goes off the rails. While teaching a male student how to put on a condom, she accidentally has sex with him, or she gives a sex lecture to a male student who failed at his first sexual encounter with his girlfriend... But it's these naughty aspects that make Megumi-sensei so good!
