The first one is called Remember Me As A Time Of Day. That's all I remember about it.
The other one is a fic set during the summer, I think, after the Ketamine treatment. It starts off with Cuddy tanning in her yard, or reading, or dozing, or something, and House runs up, and nonchalantly puts on sunscreen in a teasing way, and then I'm pretty sure they do it right there even though Cuddy tries her hardest to resist him.
Thanks for any help!
