Amateur Kurita Yoshiko visits a used-underwear shop hoping to make some extra cash, but the offer falls far short of what she wants. The manager says he will pay more if she makes the panties look freshly worn, then presses a sex toy against them until they are visibly stained. Still desperate to reach her target price, Yoshiko finally agrees to appear in porn, revealing how intensely this seemingly innocent amateur responds as her pussy becomes soaking wet.
