A female teacher with a body far from ordinary Japanese standards starts going to school with no bra and no panties. She walks the corridors, stands in class, and deals with male students, other teachers, and the guy at the school store while her pussy and breasts are fully visible. The situation turns into a school-wide uproar: she is groped, sucked, and fucked on campus because that exposed body makes studying impossible. The film follows her moving from classroom to staff room to store, keeping the no-panty no-bra state the whole time and ending in threesomes and group sex with the men around her.
