He doesn't worry about what it really means. It's not something in place of a forgotten safeword, and he's seen too much now to believe that Dean wants him to stop. Just now, in a moment that seems bounded on all sides by darkness, he doesn't even believe that Dean really cares anymore about scars, internal organs, being put in the hospital. He's not sure Dean would try to stop him regardless of what he did.
It should scare him. But this is why there's trust.
The rhythm of the baton is deeper than any of the others, like a heartbeat, steady and pounding. This time he moves past the point at which his arm starts to tire, moving over and over skin and flesh already abused to a horrifying degree. He'll have to stop very soon, or this really will go too far, and now he understands that he has to be the one to decide to stop it at all. But until that point he's going to wring everything out of it that he can.
