safe word , auch: safety word

I ask what she means by a safe word.

For example, it is common to set a safe word and to establish certain types of play as prohibited.

"Progressive," with its suggestion of moving forward, is a safe word.

"Indeed," I replied, careful to choose only the safest words possible.

The submissive had a safe word, and once they said that word, all the play stopped.

She seemed doubtful how to end her sentence, but at last took "honeymoons" as a safe word.

As with a safe word call from any other, it should herald the stopping all play and a recuperative discussion between the participants.

Usually the participants agree on a safe word; if the submissive says this word the whole play stops.

"You don't mean dominance and submission where you have safe words, do you?"
