I'll answer the question without posing another. My online slave has been on orgasm restriction but with the privilege of masturbating. As she recently came without permission, she now has been 'sentenced' to a week of 'hands off': meaning she can no longer touch herself. A simple example (plug: you can view her blog for a more detailed description of her punishment... Painslut4him).

Another 'crime' would be forgetting certain voice commands, meaning neglecting to thank her Master or use the appropriate honorific. The remedy for this might be for her to perform an exercise where she is required to ask for a physical punishment (say a crop stroke) and then thank her Master and apologize for the infraction.

Not that the above notes aren't relevant....
