She laughed softly as he grinned at her, "Oh stop it, you've always been pretty as I'm sure you're well aware." She teased right back. She'd said it more often when he was in a body other than the one he was used to, so he could be certain that she still liked him, wanted him, was attracted to him. But the fact remained that John had always been pretty, and maybe she'd just have to tell him that a little more often now to make sure he knew it even still.
The way he reacted to her own declaration made her want to say it again before he'd even asked, but when he pressed his mouth to hers she couldn't get the words out. But she kissed him back all the same, slow and happy to be back in their adult forms, to have him back in the body she'd first met him in, to be in their own bed, with their animals all around them. All of it was pretty magical if she was being entirely honest and Kitty did like to be honest, especially with John.
Eventually their lips parted and she drew in a breath and spoke again, "I love you." She told him, again, her hands on either side of his face, looping one her her legs around his keeping him close. After the week of being younger again she'd missed him. Which didn't really make sense, he'd been there with her through it all, but it had been different, and she missed this - missed having him close, missed having him in their bed with her, missed the warmth of his body pressed up against hers.
