[NippatsuKokuhou (Kaneko Ken)] CFNM in nude model

When an art club boy shatters the club's nude statue, the girls sentence him to take its place—stripping bare on the modeling platform while a roomful of smirking schoolgirls sketches every exposed inch of him. His mortification only deepens as the teasing turns hands-on: mocking his undersized cock, yanking at his foreskin, demanding an erection on command, and treating him like their personal slave instead of a classmate. Yet by the next session he's back on the platform, blushing and compliant, as a senior whispers promises of lots of fun—a humiliating CFNM ritual he can't bring himself to escape.
