FSDSS-291 "I won't tell anyone... right?" I succumb to the sweet temptation of a big-breasted female student's swimsuit, having forbidden sex at school. Yukari Mukai

Yume, a member of the swimming club, never accepts confessions from male students. Because she is in love with the swimming club advisor. A dream to seduce a married teacher by showing off her boobs and her crotch. She is a teacher who finally gives in to temptation in the pool after club activities. She crosses the boundaries of a single piece of cloth called a swimsuit... Once it's over, the forbidden relationship unfolds in the school after school.
