HUNTB-141 Transfer student is the only man at a former girls' school, cleaning turns into a panchira harem

A man transfers to a school that was all-girls until last year and finds himself the only male student, and during school cleaning, the girls' underwear keeps coming into view from every angle, making it impossible to focus on the work. When he gets an erection, the girls notice and instead of mocking him, they pull up his pants and give him a cleaning blowjob, then ask for multiple creampies.
