My female teacher, whom I had admired for three years, was instantly corrupted by my male friend's incredible penis. (Kaede Ai, SONE-705)

1/10 My virgin friend Yuzu has been secretly in love with Ms. Feng for three years, pursuing her relentlessly. Graduation is approaching, and he'll never see her again, feeling lonely... Just as he watches her wave goodbye to her students, Yuzu emerges from the restroom with her phone, saying she has some good videos to show him. —Wow, you're amazing! Although he thinks this to himself, he stubbornly replies, "I graduated long ago with that kind of stuff." That night, he masturbates while watching the videos Yuzu shows him of his teacher changing clothes, ejaculating three times. 1/15 He musters the courage to confess to his teacher, but is politely rejected, told to wait until graduation. 1/18 One day, Yuzu and his teacher go into the changing room together. 2/2 Yuzu shows him a secretly filmed video of his teacher using the restroom. But afterwards, he sees photos of his teacher and Yuzu together, even sex videos... He initially thinks it's AI-generated, but it seems real, and his legs go weak. That night, he masturbates with the videos, ejaculating three times. From February 7th to February 28th, he graduated with his virgin friend, Yuzu, and even with his idol, a teacher. He got videos from Yuzu and masturbated day and night. On March 16th, after the graduation ceremony, Yuzu called him to the cleaning supplies cabinet, saying there was something for him inside. He saw his teacher and Yuzu having passionate sex, and jealousy, regret, humiliation, desire... all sorts of emotions surged through him. He got an erection and couldn't help but ejaculate on his teacher's face. On May 27th, emotionally traumatized, he failed his university exams and was retaking them when he met Yuzu, who was enjoying a pleasant campus life. His teacher didn't date Yuzu but instead made a lot of money as a business partner on an amateur video website. He wanted to ask Yuzu for the videos, but Yuzu told him to buy them. That night, he immediately bought the videos on the website. His teacher was still lewd, masturbating with great pleasure. Ah, what exactly is youth?
