In this adult teacher-student role-play, Emi Imai visits the staff room after class and asks her homeroom teacher to punish her again. Bound in her underwear inside the gym storage room, she writhes under full-body caresses and suppresses her cries to avoid discovery, climaxing instantly when her nipples are attacked. At a hotel, she is restrained again for choking missionary sex and forced deep-throat play. Later, poor swimming grades lead to punishment in a love-hotel bath, where her teacher targets her sensitive groin with soapy hands before forcing a bathhouse-style session and spraying a huge load of semen. Their secret after-school lessons grow more intense every time.
