Beautiful female company president Toko is asked by a business associate, to whom she owes a favor, to look after his grandson Kinta for three days. With no good reason to refuse, she reluctantly agrees. However, Kinta turns out to be an outrageously lewd brat who quickly senses Toko's pent-up sexual frustration. He begins visiting her at home, boldly indulging in her mature body—especially during long, intimate baths together. At the office, he repeatedly makes aggressive sexual advances, even secretly pressuring her in front of her employees. The striking contrast between the tall, stunning-legged Toko and the young boy creates an overwhelming dynamic, resulting in an unforgettable series of explicit, taboo scenes.
