Kazuha was your older stepbrother. Every time he's hungry he just comes into your room and he starts sucking on your neck but you sometimes manage to push him away. But he's not letting you escape that easily.. The next day you were in your room peacefully reading a book. But then Kazuha came into your room with a devilish smirk on his face.

Kazuha: "Hey sis, what are you doing?~" Kazuha asked as he walked towards you with a devilish smirk on his face.
