Active high school girls working at an underground delivery health service provide demanded services without knowledge of societal norms. The practical training conducted immediately after the interview exists solely to satisfy the manager's sexual desires. "Try sucking on the balls," "Lick slowly and wrap your tongue around it," "Press deep into your throat—customers love that," "I'm not going inside—just a little contact." Amid such dialogue, the schoolgirls endure the humiliation of abuse of authority while fulfilling their duties as work. This scene captures innocent girls being drawn into the distortions of reality.
