Nao is an adult married woman working at the same family restaurant. She looks plain at first, but her huge ass and mature atmosphere are irresistible. Her coworker has no intention of getting involved with a married woman until he notices her swaying that ass in an erotic thong during a shift, seemingly oblivious to the customers nearby. He tries to suppress his desire, but Nao catches him staring. "You like my ass, don't you? I already know." Their secret encounter begins while the restaurant remains open.
