The rubber master, having received a DM from Mao saying "I'm weak against tickling," interpreted her words as a request and decided to torment her. After securing her in place, he begins by lightly tickling the soles of her feet. Though her cries are muffled by the rubber mask, Mao's teary eyes and writhing body reveal her pleasure. He then proceeds with a vibrator to deliver intense stimulation, finally suffocating her with a rubber hood to savor her helpless reactions in a complete sensory domination scene.
