Our slave, Cosmo, is bound to the bed, wearing a chastity cage for our use. Today, Yara and I have decided to make him our personal toilet. We inform him that he will only be freed from his confinement if he consumes Yara’s excrement. If he successfully accomplishes this task, I will then defecate into his mouth while Yara rides his manhood…. We begin Cosmo’s training by taunting him with our derrieres. There is also a sadistic element to our actions, as Cosmo remains locked in his chastity device. First, he is made to lick my anus, followed by Yara’s. We are enjoying ourselves, while his penis continues to throb against the cage. Yara is now prepared to defecate into Cosmo’s mouth. She positions herself directly above his face, and I ensure that her waste finds its way into his mouth! Yara has deposited a massive pile of excrement into his mouth. Yara kindly licks his chastity device to motivate him, and I force the waste into his mouth with my gloves. After all, our toilet slave must consume everything if he wishes to be freed from this cage! When Cosmo burps and struggles with the waste, Yara uses her delightful derriere to force the waste back into his mouth. Through this filthy facesitting, the excrement remains in place, Cosmo is aroused by the enticing view, and I can monitor his swallowing progress. Once our toilet has consumed everything, we release his penis from its cage. Yara then rewards him by fellating his manhood. I remove my undergarments and reveal my naked body, from which this toilet slave soon receives the next serving of excrement. While Yara rides his manhood, I force my excrement into Cosmo’s mouth, and he accepts it willingly. Then I urinate directly onto his manhood, causing it to become even harder. Since Yara and I are thoroughly satisfied with our toilet’s performance, we decide to masturbate him. To accomplish this, we use the waste that he still retains in his mouth and rub it onto his hard manhood until he ejaculates.
