Bruce wasn't going to safe-word out just because he'd been caught by surprise and discovered that his tolerance for cold was not what he would have expected it to be. Particularly not when the burning cold faded to something even hotter that had been there before, that also picked up a steady throbbing with the beat of his heart.

It took him a second or two to gather his scattered wits to argue Clark, and to take the necessary deep breath to properly steady and trust his voice.

"I really did think you wouldn't." He sounded... dryly depreciating, in spite of everything. Because he was. He was also just a little bit afraid of that flicker of red in Clark's eyes, and more than a little bit intrigued.

God help him, this was... fun.
