Double Action Punishing

Shiko held his stiff neck high as a vixen struggled to shove out an utterly large and very green chunk of turd out. He was supposed to catch it with his mouth, and pack his cavity with nothing else but the mistresses turd. His mouth now filled to capacity, he struggled to chew the fetid shit that tasted acidic and salty. He was being dominated completely, and he was now no more than a human toilet to these vixens. Pushed to the ground again, and feeling helpless, the vixens unloaded a massive turd into his mouth again, making his stomach grumble because of hunger.
