Miu-chan, who is still at an age where she looks good in a uniform, is working hard as an underground idol in between her studies. Even though she is an idol, she is still at the level of a girl who dreams. She gladly accepted the request for her first personal shoot. She doesn't seem to understand what it means to go into a hotel with a man, and at first she smiles, but gradually she becomes confused as he approaches her with his sexual desires exposed. She does as she is told, and her small breasts, which still have the core of their growth period, are played with, and her young pussy is poked, and she gets wet without knowing why, and is ready to accept a dick. Her first adult sex is when a dick thicker than her classmate's boyfriend is thrust into her without a condom. She has raw sex with a young girl who is irresponsibly impregnated, without any consideration for Miu-chan's convenience, and she cums over and over again, and is creampied until it overflows from her small vagina.
