DASS-763 Boyish, yet her body is way too developed. I found myself drawn to my younger sister, who carelessly showed off her figure. Momose Himari

After a long time apart, his younger sister Himari seemed completely boyish and lacked any feminine charm. One day, a month after he had returned home, their parents were working the night shift and would not be back until morning. Toshiya, who had been left in charge of all the housework, saw his sister in a defenseless state and could not resist his impulses. Drawn to her sweat-dampened figure, he became overly affectionate, and she responded in kind. Even after moving to the bathroom, they continued to seek each other out, then later moved to the bed and kept their intimate relationship going.
