[Seikatsu Seshishou (tt)] Danshi Seirihon

Yano‑kun, a nervous high‑school boy with bright eyes, feels an urgent need to masturbate during a dull class, prompting him to flee to the bathroom for a private release. The panels show his frantic attempts, a first cumshot, and a surprised girl noticing his distress, adding comedic tension to the everyday setting. This yaoi doujinshi blends school life with solo sexual action, highlighted by a diaper motif and the recurring theme of weak vision syndrome.
