Miu-chan, still young enough to wear a school uniform, is working hard as an underground idol between her studies. She is still at the level of a dreamy girl. She happily accepted the first request for a personal photo shoot. She seems not to understand what it means to enter a hotel with a man, and she becomes confused as she is increasingly pressured by his blatant sexual desire. She is manipulated to play with her developing small breasts and her young pussy is probed, making her wet without understanding why, preparing her to receive a cock. She experiences her first adult sex with a thicker cock than her classmate's boyfriend, bareback. She is fucked irresponsibly, made to cum repeatedly, and creampied until it overflows from her small vagina. [Additional uncut footage available on INST-196.]
