DAYD-015 Remu Nishio, a neat sister who hid an H-cup chest, and a private afternoon

Remu Nishio plays a withdrawn sister who runs the house during the day while their parents are at work. Her brother, home to rest after losing his job, finds that the sister he barely talks to has grown into a woman with a hidden H-cup chest. They end up spending the afternoon alone, and the encounter turns intimate.
