No offence but it sounds to me like somebody doesn’t know their submissive as well as they should and that somebody’s submissive has not been properly instructed in the use of safe-words.
For the record, my alpha and puddle don’t have safe-words. They are mine to do with as I please and their only limits are those I impose upon myself as a matter of commonsense.
However, I have and still do allow new ones …. Actually not a ‘stop-type’ safe-word but a Word of Release, allowing them to terminate their enslavement.
Spoken only once, I take it to mean: “Time out required to prevent accidental injury”.
Spoken twice, I take it to mean: ‘Please can we stop and have a serious talk”.
Spoken thrice, I take it to mean: “I’m sorry, please release me from my contract and return me to freedom”.
A variant on the Islamic method of divorce, in other words and it works! It works because the penalty for wilful abuse of their Word of Release (ie: using it to control their submission through time-outs) is dismissal from my service and a return to freedom whether they like it or not.
I have yet to have any abuse it!
