UZU-012 I always end up doing it with Hatoko's older sister...on a summer afternoon. - Kanna Misaki

July. A summer day. A story about a holiday. Three years older. Hatoko's older sister who lives nearby. She's also a childhood friend. We get along really well and have a relationship like brother and sister. Her personality and behavior are completely different from mine. A little free-spirited. A little eccentric. Very kind. That's the kind of older sister I am. And that's what makes me feel so good. When my girlfriend is out, she always comes into my house without permission. "I wonder if she'll come today." When she's there, I feel happy. And sometimes we have a sexual relationship. This book contains two stories about my relationship with my older sister, who is three years older than me and has been very caring since I was a child.
