Female teacher ◯◯ breeding

A naive student overhears about his favorite teacher Natsuki getting married. Furthermore, I witnessed Natsuki-sensei's extramarital sex in school. His paranoia turns into a cruel sword. I restrain Natsuki in the school's machine room and repeat 〇〇, 〇〇! Finally, even the other students... Despair 〇〇, fierce 〇〇! Natsuki's scream echoes in vain in this hopeless tragedy!!
