There is a reliable and proven method to make a slave admit that they want to eat your shit and serve as a toilet. All you need to do is insert an expanded cork or stopper into their anus and wait for their thoughts to mature. It is crucial to ensure that the cork is inserted deeply and securely in the slave’s ass. Soon enough, the slave will eagerly confess their desires. However, do not rush to remove the cork. Keep it in place throughout the entire process of emptying their bowels into their “toilet mouth” and further feeding them shit. This will add sincerity to their actions and hasten their consumption of your excrement.
