Somewhere in Tokyo, there is a men's beauty salon that employs a super busty, soft-boobed beautician who gets aroused during the massage and ends up over-serving the man. A male customer is tempted by the beautiful face and 105cm divine breasts, who whisper dirty words in his ear and give him a close-up massage, and ends up negotiating the absolutely taboo of having sex. The customer's reaction was so cute that he ended up serving him? The dangerous job of a J-cup beautician who ignores the rules and goes all the way to having sex for personal reasons.
