HBAD-689 My frustrated big-breasted, big-assed GAL sister makes me serve her whenever I have free time Alice Oto

Ayumu, who entered a preparatory school in Tokyo, is not good at living together in the school dormitory, so she is allowed to live with her sister, a gal who lives in Tokyo, but her older sister, who is a slut, keeps bringing various men into her room. Ayumu, an adolescent who is interested in naughty things because she has sex a lot, is in trouble because she is so curious that she can't study.
