Mastering the art of creating a flawless ass to mouth seal is achievable through training an individual to maintain the position for extended periods, working to extract fecal matter from the anus using suction.
When it comes to defecating directly into the mouth, it is recommended to do so in small, manageable chunks. In the event of an adverse reaction to taste or smell, the individual should be disciplined by having their face forced into the excrement they have spilled, a punishment far worse than simply swallowing it in the first place.
By employing this method, one can successfully teach all their shit-eating submissives to transfer fecal matter into their throat with no mess and no fuss.
