As her nickname "Sperm Factory" suggests, she originally worked in a kitchen. Our chance meeting through an app revealed that this high school senior already has F-cup breasts, instantly changing the atmosphere between us. When we first met, she laughed and said, "Actually, I think I might be a G now." She mentioned that boys in her class would deliberately brush their shoulders or hands against her chest. At first, she didn't understand what was happening and would just cry silently, but later admitted she felt angry and resentful. When she tried to talk to her homeroom teacher, she was dismissed with "I don't know anything about that," and even her mother refused to believe her. That's when she first began exploring self-pleasure. She reaches orgasm easily by stimulating her nipples, or by forcefully twisting and crushing her clitoris—she's highly skilled at bringing herself to pleasure. Listening to her story, I felt sadness, yet couldn't help but become aroused. She comes from Gunma, where her family runs a traditional inn, and grew up surrounded by nature, giving her a relaxed and open personality. After graduating from a vocational school for tourism, she's gained various life experiences. Now, she has no hesitation toward erotic acts. She enjoys being used casually, loves being desired by a penis, and especially gets turned on by the raw, pungent smell of semen deep in her nose, saying it heats up her womb. She didn't mind me secretly recording her, clearly enjoying the reactions captured on camera. While this video contains extreme content, there is no actual intercourse with the subject.
