A special course offered at a high-end beauty salon in Tokyo. It is a secret erotic service known only to women. The caresses are delivered with graceful and delicate fingertips, and the service is given with sticky soft lips and a thick tongue. Women squirt all kinds of fluids from all over their bodies, achieving a sense of climax and satisfaction that they could never experience during sex with a man. A hidden camera set up in the forbidden garden captures the truth.
