Momoka Izumi is a well-behaved and serious top student who never skips classes, always just watching during swimming lessons. Actually, she can't swim, so as her homeroom teacher, I propose giving her one-on-one instruction after school. She improves rapidly, looking happy with pure eyes. However, the school swimsuit looks incredibly good on a fair-skinned and slender female student. The swimsuit clings tightly after getting wet. The navy blue swimsuit accentuates her pale skin. And above all else…her nipples are unconsciously erect. Her pointy nipples can be seen even through the swimsuit. Even knowing it's wrong as a teacher, I want to touch. Even if my life is ruined, I want to touch. The nipples that unconsciously protrude under the school swimsuits drive men insane. Facing an innocent girl in her growth stage, the middle-aged teacher decided to abandon reason.
