Sara doesn't like Catherine, she's too tricky.

Of course, she did, at one point like her - love her even - otherwise why would she be here, under Catherine, groaning on the point of screaming?

Catherine gets her to whisper secrets into the night, into ears that should never hear some things. Then, as a reward of sorts, her mouth, which should never say some things, would lower itself to Sara and drive her delirious with the pain/pleasure that always comes with Catherine.

At work, she'd run into Catherine everywhere - in the break room, walking down the hall, even at crime scenes. And Catherine would be flirting with someone - Nick, Warrick, Grissom even.

Sara would wonder why she couldn't do that, couldn't place up a façade. And she would wonder even longer if that feeling in the bottom of her stomach was hunger or jealousy. It had to be hunger, because why would she be jealous?

Sara doesn't like Catherine, she's tricky. But as Catherine starts taking off her clothes, falling back into her old line of work for Sara, she knows that tonight she'll give up more secrets. That she'll scream out so loud that she'll find hersellf hoping the neighbours aren't home.

But by the time the night is done, Sara will have been tricked into thinking it isn't that bad. Anyone who can manipulate her body like that can't be that bad.
