There's a beautiful, kind, and elegant teacher at school who works in the infirmary. She always calmly takes care of the students with a gentle demeanor. Drawn to her kindness, I secretly developed feelings for her and started visiting the infirmary every day under false pretenses. One day, I went to the infirmary as usual, where Tsukino-sensei gently examined me as always. That day, I caught a glimpse of her breasts from her blouse—a first-time experience that made my heart race and my cock grow hard. Noticing my reaction, Tsukino-sensei began teaching me secret, naughty health lessons. The feelings I had in that moment burned hotter than ever before.
