The anal sex instructor in the nurses' office is every masochistic man's dream. (Kyoka Tachibana MGMQ-150)

In the infirmary... in the school toilet... the devilish beauty teacher plays with the itchy anuses of perverted M-boys! A colleague teacher with a secret "S and M" relationship secretly engages in reverse anal sex! The perverted headmaster, who steals underwear and masturbates in the toilet, gets anal sex from prostate stimulation! After school, at a secret M-sex club where he works part-time, he makes a perverted M-boy reach orgasm through hardcore reverse anal sex! A dildo is inserted into his wet anus, and his brain fluid gushes out! The orgasms just won't stop!
