T28-588 On days when my parents weren't around, I fucked my sister all day long until the sperm dried up. - Chiharu Sakurai

While Mom and Dad are away on a trip to the local hot springs, Chiharu, the aggressive younger sister, plays a naughty prank on her beloved older brother. - She has sex and ejaculates all day long, doing whatever she wants, in her brother's room, the kitchen, the entrance, the bedroom, the bathroom, etc. without any time to rest! - “Big brother is amazing! You put out so much white stuff! But you can do more, right?!”
