[An-Arc XXX (Hamo)] Hitomae de Asoko Miseru to Koufun Shichau Ko | A girl who gets excited when she shows her private parts in front of other people.

A school-uniformed student discovers that exposing herself before others sends her into a fever of excitement, first concealing a secret touch beneath the classroom desk and then becoming increasingly bold before an older, bespectacled teacher. Wary classmates become an intrusive audience as her embarrassment gives way to flushed, enthusiastic participation—“I can’t hold it back anymore”—amid rough handling and escalating group play. A provocative train encounter bookends the classroom progression, bringing her private thrill into an unmistakably public setting.
