A live-action adaptation of the popular work by Konoshiro Shinko, featuring a cool, expressionless man! Mamiya-san is the class's Madonna. I thought she had nothing to do with anything sexual, but she showed me her boobs during class... When we were alone after school, she approached me even more aggressively, even giving me a handjob while French kissing me! The next day, she finally pressed her body against mine... and my dick was rock hard! I tried my best to keep my cool, but Mamiya-san just wouldn't stop, so I ended up having a physical relationship with her...
