I had been chasing my teacher, Fuua Kaede, whom I liked for 3 years. She was a teacher I wanted to see again before graduation, but she said she would wait until after graduation. One day, I saw her and my friend Yuzuru enter the changing room together. Yuzuru showed me a video of her stealing a peep in the changing room. I thought to myself, "Wow, she's done it!" But I pretended to be strong and said, "I graduated from that kind of thing." That night, I watched the video she gave me while masturbating. I mustered up the courage to confess to her, but she politely rejected me. A few days later, I saw them together in the changing room. Yuzuru showed me a video of her stealing a peep in the toilet. After that, she took photos with me and surprisingly had sex with me... I thought it was AI-generated, but it was real. I collapsed from shock. That night, I met Yuzuru again. She was enjoying campus life. She said she was a business partner and made a lot of money from advertising amateur video sites. When I tried to get the video from her, she said, "Buy it," and I thought, "She was my friend." That night, I bought the video from the site, and I masturbated watching her incredibly lewd figure. Ah, what is youth about?
