Having just turned twenty, Misaki resolves to stay over at her beloved big brother's house, harboring deep feelings for him. This time, she boldly plans to turn their relationship into a real incestuous affair. In the sixth installment of this series, Misaki heads to her brother's place, her mischievous nature fully on display. Her older brother Haruto (25), who greets her at the door, is suffering from a cold. Concerned, Misaki begins nursing him back to health—but her intentions aren't entirely pure. Unable to resist teasing him, she replaces the cold towel with her bare breasts, sensually wiping the sweat from his body. His groin quickly swells in response, fueling her playful desires even further. She proceeds to give him a handjob and blowjob, turning her care into erotic treatment. As she warms his body with her own skin, will she finally fulfill her long-held fantasy of incest with her big brother?
