The mistress, her eyes gleaming with power, commands her crossdressing sub to lie back. She slips on a latex glove, lubing it up before sliding it into his ass. She expertly finds his prostate, massaging it until he's writhing and groaning. She removes the glove, replacing it with a thick dildo, fucking him slow and steady. Her other hand, still gloved, strokes his cock through his pantyhose, feeling it throb with need. She smirks, enjoying the control, the power, the taboo thrill of fucking a crossdressing sub.
