Kensuke is a free-lance cameraman. He, however, operates a membership adult website as well. His adult videos are popular among his members and a lot of people enjoy it. One day, he comes up with an idea for a new video, "Yes, spa series!" Like this, he visits a spa in the country and checks-in at a small spa hotel. Luckily, there are no other guests. "It won't become a big trouble even if I shoot a video here...." Research for a new spa eros series starts now.
