A sober teacher with super lame big tits who deserves the name of Fujoshi. Gals who can't help but think it's a waste to leave it as it is, make the teacher a real adult girl with every hand! ! The teacher who was shy is trained by gals and transforms into Mr. Saseko in a blink of an eye. She makes full use of the Doeroy technique without losing to the gals and entraps the men at the school.
