Even after getting married, Natsuki Hoshino is a big-breasted younger sister who loves her brother so much that she forgives him for anything.
When my husband was away on a business trip, my beloved older brother, who lived at home, suddenly moved to Tokyo. Natsuki, his older brother, offers to use her spare room, and he accepts the offer. When I asked her brother why she came to Tokyo, he told me that he broke up with her because of sex, so he wanted to hone his sex techniques at her entertainment business. However, the prostitute she was looking for had quit, so her brother, at a loss, took advantage of her younger sister's personality and offered her a place to practice.Unable to refuse her favorite older brother's request, she reluctantly accepted.
