HUNTA-998 A man becomes the only male at a former girls' school and sees panchira everywhere during cleaning

After transferring to a school that was all-female until last year, a man finds himself surrounded by girls in short skirts during cleaning duty, with glimpses of underwear constantly in view. The girls notice his erection and tease him, but then they become interested in his arousal. He ends up receiving a cleaning blowjob and multiple creampies.
