Forced feeding is a practice within the BDSM community where the submissive is forced to ingest food and liquids. This is done through BDSM gear, such as funnel gags, dribble ball gags, and the like. The practice puts the submissive person in a very vulnerable position. Trust and adherence to agreed limitations are important.
More About Forced Feeding
There are innate risks to force feeding. The submissive can potentially choke on the substance that's being fed into them. Since the act is facilitated through gags, it is harder to communicate dissent. It is crucial to agree on limitations, as well as how “no” is communicated. The dominant person should be responsible enough to look out for the well-being of the submissive.
