Ikuta Sana plays a maid who offers a forbidden "secret option" at a strict relaxation salon. She messes with her neat outfit and uses cheeky words to provoke the man's rationality to the limit. Her skillful fingers and the glimpses of her pale skin through the gaps in her maid's uniform. The thrill of not knowing when the staff will find her raises the sensitivity of the act to a critical point. In the end, she rolls up her clothes, exposes her private parts, and accepts a sense of immorality as she accepts a creampie. This is a work that stands out for the vividness of the process in which a little devil's spirit of service is corrupted and she descends into a lustful beast.
