My big-breasted, beautiful, and kind older sister is a submissive woman who obeys all sorts of men. (Hinata Tachibana, HBAD-705)

I'm a college student and live with my older sister, Hinata. Hinata is so lazy she can't get out of bed in the morning, can't tidy her room, and can't even cook. She takes care of all my troubles, helping me with everything from meals to school preparations. She's such a kind older sister. Because she's so kind, she's targeted by all sorts of men. She can't refuse anyone's suggestions and is a convenient, obedient, masochistic woman.
