So I play according to the traffic light system, Green, Yellow\Orange and Red.
If you call no, I keep going, hell, I'll even speed up or hit harder, call red and play stops before you can finish the word.
That being said, during a recent play, my sub was shouting no in the throws of one of her biggest orgasms ever, and I kept going, pushing her harder, further over the edge, keeping her orgasm going.
But then her voice changed, she said no again. This time not begging anymore, not distressed, serious. I pulled away and stopped the play, making sure she is safe and okay.
As any kind of Top, you should always read your bottom. I've recently heard some bottoms are too scared to call red, making it even more your responsibility to take control and take charge. Know when to stop even if they did not call red. There are many ways they can call red without saying a single word.
Please, I beg of you, take notice of your bottom. There is a switch in their behavior. Know when to stop
