Ten minutes after the graduation ceremony ended, I'm in a love hotel with a girl who was my student until just a moment ago. She says, "Now that I've graduated, this is legal, right?" I wonder if this is truly permissible... A year ago, I suddenly took over a third-year class because the original homeroom teacher went on maternity leave. As I got to know everyone, there was one girl who showed me an unusual amount of affection. That was Hamabe. For someone like me, who has never been popular in my life, I couldn't help but be happy about the affection from a girl, even if she was my student. Still, I restrained myself from making a move. But Hamabe continued to tease and seduce me at every opportunity. As graduation approached, she whispered to me, "Please hold me after the graduation ceremony..." And that brings us to now. I've reached my limit. This girl is no longer my student, and we are about to have sex—
