She didn't look like the type, but Kensi did, in fact, use perfume.
When Deeks had first found out this deep, dark secret of hers, he had bit his lip and put the bottle back into her gym bag, deciding to set his knowledge of it aside for a rainy day in their relationship. They had only just been partnered up to work together, and while most of their conversations did consist of almost playful pokes and prods at the other, she didn't need to know he was going through her things.
Not just yet, anyway.
So he pushed it to the back of his mind, saving it for the moment the perfect comment would be needed, a single line that would win him their little game for weeks to come. Kensi Blye would have no other choice but to bow before his ultimate skill in word craft, his natural ability to create comebacks on the fly, and all would be well in his world.
It would be a day to remember for posterity, and he was just waiting for it to come.
He never got the chance, for just a few weeks after he found the bottle, Kensi hugged him and he smelled its contents.
He had no clue what it was supposed to smell like, no idea what it was supposed to even be, but even in his wildest dreams he never could have conjured up the way she smelled, his nose buried into her hair as he held her. A mixture of whatever was in the bottle and just her, something he never could have done justice even if he had tried. A smell he wanted on his pillow in the morning and his shirts at night, just so it would never fade from his mind.
He never got to use his comeback, for every time he thought of that bottle, her scent assaulted him just as strongly as the first time, and he became distracted by the desire to smell it again.
