Punishment can be in any realm really ... it doesn't have to involve pain, it could involve degradation and humiliation ... or it could involve wearing a specific item of clothing against her wishes ... or doing something that she doesn't quite enjoy ... or as I said ... anything.

For instance, if I were a submissive, a Dominant might choose to punish me for using so many damn ellipses and chose to make me write 1,500 words free flow without being able to use ellipses.

On the other end of the spectrum, there is the physical punishment - i.e. spankings, slapping of the face, pinching, tickling, etc. etc.

The realm of punishments really has no boundaries.
