HBAD-696 _The younger sister often wears short skirts to solicit sex from her older brother

Living with my step-sister makes me uncomfortable, especially when we are both grown up and starting to be independent. Furthermore, my step-sister, Himari Aizuki, has physical and mental problems. She often comes close to me and deliberately lifts her skirt to reveal her underwear. I knew this girl's intention was to set me up to do bad things, so I outplayed it by inviting my best friend over to my house and she and I "teached" this girl a lesson, to know that if she wanted to seduce Big Brother, then TWO would give her butterfly balls!
