Ass fucked anal crazy sub slut takes it deep

That's highly unlikely. Now, if you want to stop, how would you like to do so? Do you just want to use natural language?

In which case you could say "stop" or "no" or "I don't like that." Or do you want to use a safe word?

Yeah, I like to use a safe word because sometimes when you're hitting me or whatever I might say "stop" but not like really mean "stop."

So I like to use the stop lights.

I don't know what the fuck this is but who cares.
