A beautiful female CEO, Touko, is asked by the CEO of a business partner to whom she owes a debt of gratitude to take care of his grandson, Kinta, for three days. She can't refuse the request of her benefactor, so she agrees, but it turns out that Kinta is an incredibly perverted brat! Kinta sees through Touko's sexual frustration, and makes repeated naughty demands of Touko, showing off his precociousness wherever he goes! He visits her at home and thoroughly enjoys her adult body in the bath, and at work, he begs her for sexual relief many times, hiding from the other employees. The contrast between the tall, beautiful- Namiki Tago and the little shit boy is stunning! It's full of scenes that will never be possible again!
