When it's House, Chase can't resist reacting. But, more than that, he can't resist pushing, either. He was a brat, albeit coy and teasing, playful more than petulant. So there's a small smile that curves his mouth when House calls him on it. And then he gasps, his body jerking as the impact of House's hand on his ass comes harder, sharper. He knows it's not as hard as the man can give it to him, but he's not trying to get himself too over his head. At least not yet.

So there's a slight look for a brief moment, but he doesn't needle him about it. Of course, the spanking might have something to do with that too. The impacts are hard enough to start warming his skin, no doubt turning pale skin rosy as it continues. He's not squirming yet, but the impact is sharp enough that he's not quiet, either. There's soft sounds, gasps and murmurs, his body not actively trying to squirm away, but he's not staying still, either.

"If I didn't.. know better.. I'd think you were just looking for an excuse," Chase muses outloud, unable to entirely keep his mouth shut. He likes House, wants him, but that fact is as worrying as it is enthralling. There's something about him that keeps drawing Chase in, keeps tempting him into pushing.
