I'm a rookie homeroom teacher who loves black tights more than anything. While conducting after-school supplementary lessons in the classroom, I can't help but stare at the black-tights-clad legs extending from the uniform of my always serious and kind student. One day, unable to hold back, I asked her to "rub against each other." With a troubled look on her face, the kind girl granted my wish, saying, "If you insist, teacher..." She lets me rub my cheeks against her legs, which wear 40 to 140 denier tights throughout the seasons, lets me gently step on her, and even lets me smell her steamy feet. "Does this feel good?" she asks, serving me with a kindness that pampers me, pushing my rationality far beyond its limit. Kaho herself seems a bit embarrassed by the rough texture and friction sound of the tights, but she still rubs her sweaty bare legs against me for my sake. Finally, I tear only the minimum necessary part of her black tights for a forbidden raw insertion. Kind to the very end, Kaho accepted me anywhere on campus while remaining clothed, saying, "Until you're satisfied, teacher."
