The depraved father, who has been sexually conditioning his own daughter Lala (142cm, hairless) with twisted affection, now sets his sights on her 136cm, hairless cousin YUKA, who he's taking care of during summer vacation. "Lala, show YUKA a demonstration," he says. YUKA, who was terrified of Lala's abnormal incestuous behavior because they were close like sisters with their kind uncle, finds her undeveloped body gradually being conditioned and eventually starts performing oral sex, swallowing cum, begging for creampies, and giving him blowjobs on her own. And so... it becomes commonplace for the two cousins to serve their "uncle" together in a friendly manner.
