Clarity and Safe words
As we’ve already mentioned, it’s good to select a “safeword”: a special word, which wouldn’t come up in the role you’re playing, that you and your partner agree will mean you’ll pause whatever you’re doing and talk to each other “out of role.” If nothing else you can just use the word “safeword” itself.
If you two have never done any kind of role playing before, then it might also be helpful for each of you to think over and share whether there’s anything you could conceivably be asked to do that you know you’d never want to do (also known as a “hard limit”).
I’ve only really played with 2 people. To date, my safe...been classic one word song...
