As the night wore on, Lady Vampira's transformation into a rubber dominatrix was nearing completion. Her perfect body was encased within layers of latex, from her form-fitting catsuit to the elaborate hood that covered her head. The hood had two eye-holes, barely large enough to allow her to see, and a ventilator system that forced air into her lungs.
The room was filled with the sound of heavy breathing as Lady Vampira moved around, adjusting straps and buckles on the equipment she had prepared for her next victim. She picked up a gas mask, hissing softly as it connected with the ventilation system. The mask had a tube that led from it, ending in a plastic bulb, which Lady Vampira squeezed gently, releasing a stream of air into the mask.
With a satisfied smile, she positioned the rubber-lined gas mask over her slave's mouth and nose, fastening it securely behind his head. The slave gasped, his body tensing as he felt the rubber seal against his skin. The air flow from the ventilator was set at a reduced rate, making it harder for the slave to breathe.
Next, Lady Vampira attached a length of clear plastic tubing to the end of the mask's tube, allowing her to control the flow of air to her slave. She dipped the other end of the tubing into a nearby bucket filled with her divine pee, creating a bubbling sound as the urine flowed through the tube and into the mask.
The slave's whimpers turned into muffled groans as the warm, stagnant pee filled his nostrils and mouth, choking him as he struggled to breathe. He couldn't see or hear properly, and the reduced oxygen levels were making him light-headed. All he could feel was the soft rubber of his mistress's outfit against his skin, and the unyielding straps and buckles holding him in place.
Lady Vampira watched with delight as her slave's body began to tremble, the gasps for air becoming more desperate. Smiling beneath her obscured visage, she removed the penis cage that had been restricting her little sissy's cock and placed a vibrator against his asshole instead.
With a flick of a switch, the Magic Wand vibrated against the slave's sensitive flesh, sending waves of pleasure coursing through him despite his predicament. The dual sensations of pleasure and pain, of being both dominated and aroused, was part of the thrill for Lady Vampira and her slave.
As he neared climax, Lady Vampira increased the intensity of the vibrations, watching as his body arched in response. Just when she could see the edge of his orgasm, she stopped the vibrations and withdrew the toy from his asshole. The sudden absence of stimulation combined with the chloroformed gas and tight bondage sent the slave spiraling into blissful oblivion.
With a satisfied smile, Lady Vampira unhooked the plastic bag from around her slave's head, removing the source of both his discomfort and his arousal. She undid the straps holding him in place, letting him collapse to the floor in a heap.
"Thank you, milady," he murmured, his voice muffled from the gas mask and still unused to the sensation of speaking through it.
Lady Vampira chuckled softly. "Don't thank me yet, my little sissy. Your Rubberdoll Sissyfication is far from over."
