Ane Miko no In'yoku Naru Gishiki ~Gaman Dekinai Boku~

Synopsis

In a remote rural area, far from the city, there is a shrine run by my grandfather. Every year, my older sister visits there to help out my grandfather as a shrine maiden. This summer vacation, I happened to be visiting my older sister and my grandfather's house. When we got there, I found myself faced with a hectic schedule. I was constantly bombarded with chores, told to do this and that... But no matter how cruelly my grandfather treats me, I have my older sister.

My sister, who was supposed to be sleeping next to me, was gone. While casually searching for her on my way to the bathroom, I witnessed a shocking sight. "Hmm, hmm...please...stop it..."
