Bijin sales lady: Ushirokara yogose (2006)

Yuko, a water purifier saleswoman, works desperately to save money for her wedding, but her sales figures aren't improving. One afternoon, she breaks into a house she's visiting and finds a burglar. Yuko tries her best to sell to the man posing as the homeowner, but he doesn't pay any attention to what she's saying. That's because his eyes are glued to Yuko's large breasts.
