Kokoro Amami's fourth work, which marks her graduation from the Seishun Jidai label, is a "creampie lifted" work. She overcomes the barriers she had always been interested in but had never taken the plunge, and challenges herself to her first ever creampie sex. A raw cock is inserted into her still-developing small slit, and as thick semen is poured into her, the girl takes another step closer to becoming an adult.
