[Nakaura Tomoki] Ueno-kun Has Been Developed Chapter 15

Ueno, a nervous bespectacled youth, is confronted by a dominant female who threatens to expose his secret unless he obeys, a clash that erupts into a heated, rain‑soaked encounter titled "Dirty Panties". In a cramped bathroom he lets himself become corrupted, confessing that he is turning into a pervert while the promise to never again climax for Chisaki looms over him. The escalating power play and forbidden desire drive the story forward, promising a tantalizing continuation of his development.
