FSDSS-291 "I won't tell anyone...?" Yume Nikaido gives in to the sweet temptation of a big-breasted female student through her competitive swimsuit and has forbidden sex inside the school

Yume, a member of the swimming club, never accepts confessions from male students. - This is because she is in love with the swimming club advisor. - A dream of seducing a married teacher by showing off her breasts and crotch. - A teacher who finally succumbs to temptation at the pool after club activities. - It goes beyond the boundaries of a single piece of cloth called a swimsuit. - If you go beyond that, you will end up with a forbidden relationship that takes place inside the school after school.
