He wanted to sink back against the wall and relax, to let the pain wash over him, but it didn't stop. Every time he thought she'd let him have a break, she found somewhere else to cut, somewhere else to bite. Every muscle in his body tense, he watched her through half-lidded eyes, his breathing heavy and ragged. And when she released her grip on the knife in his shoulder, he was careful not to move in any way that might dislodge it, but not moving at all wasn't an option - especially not when she moved down to his thigh. He actually jolted a little, his breath catching in his throat again; it was just a little too close to other parts of his anatomy that he'd very much like to keep intact. But for the moment, she seemed content to simply drag the knife along his leg, and he relaxed slightly, still watching her. After a moment of consideration, he drew the other knife he'd taken from her from his belt, and held it out to her, freely offering it to her to take back.
