UZU-012 - With my cousin sister, it always ends up happening… a summer afternoon.

July. A summer day. A story about a holiday. Three years older. A cousin sister who lives nearby. A childhood friend and a very close sibling-like relationship. Her personality and behavior are completely different from mine. A little free-spirited and slightly eccentric. Very kind. That sister. It's very comfortable. She always comes into my house without permission when she's not home. "I wonder if she's here today." I'm happy when she is. And sometimes we have a sexual relationship. Recording the relationship between a three-year-older cousin sister who has always taken care of me since childhood, for two people.
