Bull shivers, goosebumps down his back at the touch, or was it the words, or maybe that heat. He licks his lips, willing his voice to work again. He hadn't entirely expected this to work, for Clark to be as into this as he is.

"Thank you sir." He shifts ever so slightly, reaching behind him to pull Clark a little closer. It is a gentle touch, more a nudge. But it is still there. If Clark thought he was getting some docile little lamb he is mistaken. Bull might be claimed, and he will take orders, but until those orders arrive, he does what he wants, and right now he wants Clark as close as he can.
