MKON-020 My little sister loves me too much and was caught by the teacher masturbating in the classroom while smelling her gym clothes… Is she Mikami?

Film Introduction

My name is Soichi. This is my sister Rika. She's one year younger and goes to the same academy as me. She's good at taking care of people, and as her brother, I'm just right for her to admire. Every day, my cute little sister wakes me up in the morning, I have breakfast made by my sister, and we go to school together happily. It must be a happy life that any man would envy.
