Two Mistresses Turn Slave Into a Human Toilet

Miss Medea and I have bound our slave completely in tight mummification, leaving him utterly helpless for a deep, nourishing toilet training session.
We start by securing a funnel between his lips and take turns emptying our bladders, flooding his mouth with hot, fresh piss. He is made to swallow every warm drop while we watch his desperation grow.
Then I position myself above his face and push my warm shit straight into his open mouth. Still dirty, I lower my perfect ass onto the thick dildo strapped directly to his locked chastity cage and ride it slowly, grinding with pleasure as he lies trapped beneath me, knowing this sensation will never be for his own denied cock.
For the ultimate indulgence, I fill Miss Medeas tight asshole with rich chocolate pralines. They melt deliciously in the heat of her fresh shit, creating a sticky, decadent mixture. She squats over his face and empties the warm chocolate-scented load directly down his throat, commanding him to chew thoroughly and swallow every filthy, sweet piece.
Only once he has completely devoured our special fecal pralines do we unlock his chastity cage. His reward is a desperate orgasm, followed by a final warm piss rinse.
