Inako-chan is a petite high school girl. Because of her height, everyone constantly starts to "bitch" to her and patronize her. Only her half-brother knows what she's really like... There's a sexy monster in her small body, who doesn't feel bad about her size at all. She often wakes up her brother with a very original method, and after dinner, her brother can often "thank" her. And when her brother is not in the mood, she can go to extreme measures to satisfy her lust. The local sex clubs know her like the back of her hand.
