ADN-656 English Sub – Hinata’s older sister is usually quiet and it’s hard to tell what she’s thinking. Because of this, Hinata finds her a bit intimidating. However, her sister is beautiful and often goes braless at home, which makes her nipples visible and erect, making Hinata find it strangely erotic. This had become something Hinata looked forward to when visiting her sister’s house. One day, it seemed that her sister had gotten into a fight with her casual sex partner, and she was in a very bad mood. Hinata couldn’t help but think that having a casual sex partner as beautiful as her sister would be great, but then she realized that her sister was considering her as a potential new casual sex partner.
