One day, a flyer from a newly opened massage parlor arrived in the couple's mailbox. Chisato's husband suggested they try it out, so they visited the shop together. Inside, treatment rooms were separated by partitions. The Shoda couple each lay down on separate massage tables. At first, it seemed like an ordinary massage parlor—but gradually, things changed. The therapist's fingers began focusing on sensitive areas, stimulating them in a seductive manner. Chisato felt slightly uneasy, but her husband seemed extremely satisfied, saying he wanted to come back again next week. It was as if they were being drawn into a world far removed from their daily lives—one filled with subtle temptation.
