Onee-chan to Shota-kun to.: Naka wo Yoku Suru H no Kankei
お姉ちゃんとショータくんと。～ナカを良くするHのカンケイ～
Shouta loves his older sister, Azusa, but she has been acting cold toward him ever since an embarrassing incident in the bath. Determined to mend their once close bond, he struggles to understand why she keeps her distance.
When their father leaves on a business trip, Azusa invites her two best friends, Natsuki and Honami, to stay over. However, the friends have their own plans: they decide to teach the siblings a naughty way to reconcile, pushing Shouta and Azusa into a series of intimate situations that blur the line between sibling affection and something more.
