The true definition of swamp ass is only for the ultimate revenge seekers and when you really want to degrade and rob a person of their dignity for cruel things or crimes committed against you or your family. You knock them out and rape their ass and when they wake up it is your cum causing them to have the disgusting feeling of a swampy wet blown out ass.
