Ella grinned, as much as a serval could grin, though it probably looked more like she was baring her teeth at him more than anything. Grinning, baring, it was all the same when it came to Terrence. She swiped at him again, animal body vibrating with her purrs mixed with playful growls as she hooked her forelegs around his neck. And then she transformed back into her human form, laughing in return, even as she caught his mouth with her own, laughing against his lips. Merlin, she wanted him, too. This want was so different than her desire for him had been recently, though no less intense. The intensity, however, had melded into something far more light-hearted than the way she wanted him when she feared one or both of them might not be around tomorrow.
While she snogged him, one hand fell away from him and her fingers dug into the snow, wrapping around something not quite the shape of a snowball, and pelted the side of Terrence's head with it. He may have pinned her, but she never stopped the fight.
