Description: Riku Ohmi works as a substitute janitor in a swimming training facility. His life changed when he found a lot of video tapes sneakily recorded. In the video tapes, there was a scene a man, who was probably a predecessor, was molesting a girl in swimsuit. Then Riku found that the predecessor was always taking sneak pictures and had a perversion for swimsuits. Riku began taking peep at the girls in the facility and videotaping their masturbation. He used it for blackmail to score some sex on these girls.
