Otoshira Sayaka, 19, is actually a 19-year-old man who has never dated a boy before, but tries to enter the world of adulthood. She has always loved idols and sexy actresses and has longed for a world in front of such people. Her face and personality are innocent and cute...but she is 169cm tall and has an adult-like proportion. This is the first real-life AV work in which she shows off her first sex while shaking between curiosity and anxiety. It overflows with energy and purity.
