OPG-0019 When I played a prank on my busty niece and finished inside her, she became even cuter and more intense! Hoshino Natsuki

On the anniversary of her mother’s death, Natsuki visits the grave with her father to report that she has graduated from school, and there she reunites with her mother’s younger brother, Masahiro, whom she has not seen in a long time. Later, on the day her father is away on a business trip, Masahiro comes over with a graduation gift.

Masahiro becomes infatuated with Natsuki’s grown-up body, despite her still youthful face. He secretly mixes a sleeping aid into a cake, takes advantage of her while she is asleep, and violates her. As he repeatedly fondles her and toys with her body, Natsuki gradually becomes captivated by her uncle’s touch.
