Lusty. So that's his name in this house to be branded in. So... it's forever then. Unless Master decides he wants to burn over it and sell him.
He takes a breath and accepts the strip of leather, biting down as hard as he can, bracing. Dog might be able to see he's breaking into a sweat from the effort to not just... run away like he wants.
He knows that that means things... limbs, genitals, fingers, toes... will be cut off and there's worse things than branding and accepting Master's kindness. It is a kindness isn't it? To be wanted?

The impact feels at first like being stung. Then it burns. Tears fall, unbidden. It hurts. It hurts more that a switch to ones feet.
