I got my first girlfriend. She's cute and kind, and I'm proud of her. I have no experience in love, so all I can do is hold hands and kiss her... Then I meet up with my senior, who is famous for being a bad guy. He raped my girlfriend. He straddled her with his weight three times hers, immobilizing her due to the difference in our physiques, and made her cum over and over again. That kind of sex made her fall in love with him, and she was taken by him before I had even had sex with him once...
