Catherine pretended to concentrate on the blood drops beneath the car seat, but her mind was in another place. She inhaled deeply, Sara's perfume washing through her body and intensifying the throbbing between her legs. She glanced at the brunette often, mesmerized by the passion and beauty she saw with each stolen look.

Closing her eyes to steady the desire that was growing, she wondered if Sara could feel the heat which emanated from her body. Did she sense each time blue eyes were undressing her? Catherine hoped so, but knew the answer was no.

The longing in her centre grew stronger, and flustered, she took off her jacket. The heat didn't lessen, and she could feel droplets of perspiration on her top lip. She glanced up again and this time, was met by chocolate eyes. The brunette didn't look away, she seemed to be searching Catherine's face, reaching mentally inside the blonde for hidden truths. Catherine smiled nervously, she was sure Sara could see how aroused she was and she felt utterly ashamed.

When Sara spoke, Catherine had to suck hard to catch a breath. Did she just say what she thought she just said?

"Do you wanna jump in the back seat with me Catherine?"

The blonde stuttered, unsure of what to say. "Sure." was all she could force through dry lips.

They sat in the back seat, looking at each other in silence. Catherine started to lean forwards, closing her eyes as she prepared to meet Sara's lips.

"Ummm, Cath? Are you ok? Now, here's what I wanted to show you..." She pointed to a small stain on the shelf behind the seat.

Catherine froze, mortified as she realised she had misread Sara's invitation.

"I need some air." she mumbled, unable to meet Sara's eyes. Stumbling out of the car she exhaled deeply, hoping to rid herself of some of the embarrassment that was consuming her.

Outside, Catherine sat with her head between her knees. How could she have been so stupid, so driven by lust? She didn't notice when Sara sat down beside her.

She looked up quickly as the brunette jangled her car keys.

"Oh, Sara...I..."

"Shhh. Don't speak, just put your hand in mine and I'll take you for the drive of your life Catherine Willows."

"But, back there... I thought you meant... I made a fool of myself." She lowered her head.

Sara placed a gentle finger beneath her chin and lifted her face to meet her own. "I did mean it. Just not there, wouldn't want to contaminate the evidence now would we?"

Catherine couldn't help but laugh at Sara's cheeky grin. She moaned softly as delicate lips brushed against her own, Sara's fingers tracing her collar bone as they tasted each other, tongues fighting for control.

An hour later they lay panting, bodies tangled and trembling, too weak to lift their heads. Catherine smiled as Sara cupped her face and kissed her, their air mixing as they struggled to breathe.

"So, my two favourite CSI's, what you got for me regarding the car?"

The two women looked at each other with knowing smiles.

"Well Grissom, We gave it a full going over and I thought we'd investigated every single centimetre..."

"But we need to give the back seat another thorough search..." Catherine finished Sara's sentence and they both looked at each other again, desire heavy in the air.

"Well, what are you waiting for ladies, put all your energy into it..."

"We will Gris, don't you worry."

They left the office and walked straight past the garage, heading instead for Catherine's SUV. Gently lowering Sara backwards onto the seat, Catherine smiled. "I'll put all my energy into this investigation Miss Sidle..." She whispered as she crouched between Sara's open legs.
