I'd like to leave some intelligent, meaningful comments, but my brain got fried on first reading, and it hasn't got any better on subsequent ones! This is mindbendingly hot; as much as anything because your characterisations are so flawless. This is how I see Warrick - no, not nekkid (though that works) - but "...heat and mystery and hard lines and planes...". I love how Catherine's primary focus is Nick, but it doesn't stop her thinking about Warrick, and her ongoing analysis even in the midst of such heat is so in character.

But can I just say about the sounds Nick makes? Guh.
