[Natsuiro Otome (Nakagawa Ryna)] Sexual Punishment ~Ass in the Wall Janitor~

At a discipline center where convicted criminals serve their sentences as wall-mounted asses, janitor Rousuke Ashihara clocks in for another shift hosing down gaping, graffiti-covered male cumdumps. Marriage fraudster Hiroki Toyama gets the full treatment—collared, plugged, flushed with enemas, and pounded through the wall with relentless anal and orgasm denial until he's a drooling, cross-eyed ahegao mess begging to cum. By the last page, the stoic cleaner has joined in himself, both men sweat-drenched and grinning as they dare the arriving officers to arrest them all over again.
