A family of four: father, mother, older brother, and younger sister. The father is horny, the mother is dull and laid-back, the older brother is also horny, and the younger sister is cute and full of energy, like an idol in the family. It's troublesome how defenseless the sister is living with these horny men. A young sister of that age has a body that reason can't control. I want to fuck her no matter what. I want to sneak past mom's eyes and somehow fuck her...
