A 20-year-old rookie male idol, 170cm tall and weighing 58kg, traveled far by bullet train for this shoot. Despite his cute, boyish looks, his standout feature is his large cock. Facing the camera for the first time in a masturbation challenge, he nervously opts for a "barely-there mosaic" that clearly reveals the shape and squishy movement of his genitals. His first public masturbation is a mix of nervous excitement and raw arousal. Watching a porn video, he acts out a fantasy of being jerked off by a partner. Ah, I'm gonna cum, ah! I'm cumming! Ah! Ah! Aaah... His honest, innocent reactions feel like a genuine first-time experience, deeply moving the viewer. Captured in intense, realistic detail as the latest release from RAINBOW PICTURES-ANGEL, this film goes beyond mere masturbation, fully expressing his emotions and responses in a bold new way.
