The nephew, who is actually interested in his aunt, is alone with her in a hotel for various reasons. Unaware of this, the nephew becomes excited by his aunt's careless flashing and skinship, and gets an erection. Furthermore, while sleeping in a close position, he can no longer resist and hugs his aunt. At first, she refuses, but as she gently leads him for his nephew's sake, he becomes aroused and starts shaking his hips violently.
