I couldn't resist the temptation. I saw the female student's soaked swimsuit and her unsuspecting nipples... As a homeroom teacher, I lost my mind and engaged in forbidden sexual intercourse with her during a one-on-one tutoring session after class. (Izumi Momoka MIDA-449)

Izumi Momoka was a quiet, diligent, and excellent student. She couldn't even skip class, and she only watched swimming lessons. Actually, she couldn't swim, so as her homeroom teacher, I suggested one-on-one instruction after school. Momoka improved rapidly, her innocent eyes filled with joy. However, for a fair-skinned, slender girl, a swimsuit was simply too perfect. The swimsuit clung tightly to her body, soaked with water. The dark blue swimsuit accentuated her fair skin. And most importantly… her nipples were unconsciously erect. Even through the swimsuit, her hard nipples were visible. Even knowing it was inappropriate for a homeroom teacher, I still wanted to touch them. Even after life's setbacks, I still wanted to touch them. The unconsciously protruding nipples against the swimsuit would shatter a man's rationality. Faced with an innocent girl in the throes of adolescence, the middle-aged teacher decided to abandon reason.
