Professor Shino's Classes in Seduction

Sakurai Shino is a beautiful chemistry teacher who has just transferred to Shirakumo Academy. Her elegant appearance and glasses make her the envy of the entire school. One day, a female student named Iijima Sayaka confides in her about her worries regarding sex, and Shino decides to give her a private "lesson."

That same night, Shino becomes aroused and begins to pleasure herself in her room. Suddenly, a male student named Kayama breaks in and rapes her, leaving her physically and emotionally battered. Despite the trauma, Shino goes to school the next morning as if nothing happened. Kayama then calls her again, intending to assault her once more, setting the stage for a dark and twisted relationship.
