I want to be a child of "Hinata" ... I fight in front of my mother and breastfeed when it's just the two of us.A gentle younger sister who let her suck her nipples since puberty.Her nipples are pink enough to tell her friends.One day at breakfast, she suddenly hears about her boyfriend from her mother.That day, when she tries to question her sister, she can't control her emotions and pushes her down. (Hinata is mine for the rest of my life) She had forbidden sex for the first time that day... "Brother, are you angry? Your boyfriend is about your brother."
