A new label "Seishun Jidai" has launched, where beautiful girls with overwhelming clarity will make their debut. Nozomi Nishino, 150cm tall and slender, is a quiet 18-year-old who grew up in an all-girls school. After her first sexual experience, she was not satisfied with the masturbation she learned, and she had a desire to be raped forcefully. The girl, torn between Kokoro and anxiety, becomes a little more mature as she writhes in pleasure for the first time.
