Mistress Jane walked into the dimly lit, secluded room. She had already picked out the slave to be her subject for tonight's little experiment. The slave, a young and somewhat weak man, knelt in front of her with his hands tied behind his back. His eyes met Mistress Jane's, filled with a mixture of fear and hope.
"Now, now," Mistress Jane chuckled softly, her tone filled with cruel amusement, "don't worry, this won't hurt too much. At least not physically." She moved closer to the trembling man, her ass within inches of his face. "You see," she purred, "tonight, I want to test how long you can hold your breath."
Without further warning, Mistress Jane lowered herself onto the man's face, pressing her nylon-clad ass firmly against his mouth and nose. The slave gasped for air, his chest heaving desperately as he tried to breathe in through his small remaining air pocket. But it was no use; Mistress Jane's weight held him down, making it almost impossible for him to move.
For what felt like an eternity, the slave waited for Mistress Jane to get up from him. But she didn't move. Seconds turned into minutes, and still, she remained sitting on his face. Panic began to set in; the slave's vision started to blur, and his head felt light. He couldn't regulate his oxygen intake anymore; all he could do was focus on her ass - waiting for her to get up just so he could have a sliver of air.
Finally, after what seemed like an eternity, Mistress Jane lifted herself off him. The slave gulped in huge mouthfuls of air, his chest heaving as he struggled to catch his breath. Tears streamed down his face, his cheeks stinging from the pressure. He glanced up at Mistress Jane, expecting to see some sense of satisfaction on her face. Instead, she looked almost bored.
She leaned down next to his ear, her warm breath caressing his skin. "You see, slave," she whispered softly, "I could have sat on you forever if I wanted to. But I was curious - how long could you really hold your breath?" She straightened up, grinning cruelly. "I'm glad to see you lasted as long as you did. But just remember - next time, the stakes might be higher."
With that, Mistress Jane walked away, leaving the trembling slave on the cold floor. He tried to wipe away the tears, but they kept coming. All he could think about was her ass, looming over him like a shadow. But despite his fear and the pain, he couldn't help but feel a strange sense of accomplishment – he had held his breath longer than he ever thought possible.
