I’ve ever safe worded in a pro session but I have played privately in a CNC context. II think with pro dommes most are unlikely to push past limits unless you have a long-standing relationship.

Playing with someone with whom you have a committed relationship is different. I’ve played in the past with what we call a limit safe word. It would cause the Mistress to pause and evaluate the problem but not necessarily stop the activity. The idea was that it was primarily intended to bring safety issues like circulation or breathing problems to her attention. To add spice we agreed that use of the safe word would have a price. In the past that’s been things like a pretty severe caning that pushed me out of my comfort zone, an extended period of isolation bondage or one of my least favourites……a generous coating of capsaicin cream on my cock and balls and then being left for 30 minutes or so to experience the sensations.

I should point out that I would never enter into this type of scene unless it was with someone I knew intimately and trusted completely.
