OBA-131 My Female Teacher Is Unintentionally Leading Me To Temptation With Her Loosened Bra Nobuko Terabayashi

With only one year remaining in my fun school life, my longing teacher, Mr. Terabayashi, has finally become my homeroom teacher. The most popular teacher in the school, kind and beautiful, is my ideal teacher. However, recently my grades have dropped for some reason. It's because the teacher's chest is too defenseless to study at all. Just seeing a bra makes my heart pound, but I can see my nipples... And I ended up doing a detention class alone with the teacher who was worried about my grades.
