Miu Kimura and Noha Yamashita, novice kittens in the art of rope bondage, are introduced to the world of BDSM by two experienced mistresses. They are secured in intricate shibari knots, their bodies stretched and exposed. The mistresses use crops and paddles to punish the squirming girls, leaving welts and marks on their skin. The intense sensation drives Miu and Noha to the edge of orgasm, but their mistresses deny them release, leaving them craving more.
