Yara and I already chained our slave Cosmo to the bed. Since yesterday he is in a penis cage, because we were not satisfied with his last slave training. He has to make up for that today by eating both of our shit today. Yara and I decide that he must stay in the cage until he has completely swallowed my scat. We tease our slave, because he should become really horny and long for our shit. I facesit him with my latex ass and Yara licks his chastity cage. Slowly but surely we turn him into a helpless victim. I command Cosmo to lick my asshole before I then poop my shit portion in his mouth. He has to eat that now if he wants to get out of the penis cage! With a lot of pressure we make him swallow every single bite. Yara and I press our hand onto his mouth, so he has to swallow. We are ready to use different methods: Be it endless teasing or mouth spreaders and inflatable pumps…. Cosmo actually manages to eat my shit completely. After that he is freed from the penis cage. As a reward, he gets even more shit! Yara poops more and more scat into his mouth and we expect him to swallow! Alternately we jerk him off and use a butterfly mouth spreader and an inflatable pump to get the shit into him. Because I am so generous, I poop onto his face again, even though there is already a huge pile of shit in & on his mouth. We animate him to swallow and push everything into him! Yara tries to motivate him with blowjob and handjob, while I dominate him mercilessly. In the end, our filthy toilet literally explodes after this strict and extreme scat feeding.
