IPX-205 Nanami Misaki, a younger sister who was forced to serve her brother-in-law while despising her step-brother for a week without her parents

Nanami, who was living alone with her father, suddenly finds herself in the presence of a big brother-in-law...Even though the situation is the worst, he ends up watching her secretly masturbating while wearing high-end lingerie. I decided to comply with my brother-in-law's request in exchange for not telling him about it for a week while my parents were on a trip! No matter how much I despise it or how disgusting I insult it, my body still reacts when I'm touched through my lingerie.
