I'm a timid boy and I was the target of bullying at school. Natsu-sensei, who is kind and considerate of students, helped me. However, because of this, delinquents spotted her and drugged her with an aphrodisiac. I could not help Natsu-sensei, who was gradually falling into Kimeseku pleasure that was repeated over and over again, and I could only get an erection when I saw it.
