The crew visits Katsushika, home to Shibamata and Kameari, to pick up a married woman. After repeated rejection, they spot the elegant, long-legged Natsuki Seko in a miniskirt. She initially enters the car but leaves to prepare dinner, taking their phone number with her. When she learns her husband will be late, she calls back and returns to meet them. Beneath her shy exterior is a powerful sexual appetite, and once aroused she reveals just how uninhibited she can be.
