Gil stared at the package. There was a blow up doll in his office. He was pretty sure it was female, but it certainly wasn’t anatomically correct. He closed the door to his office and walked over to the bubble-wrapped parcel and picked up the post-it note attached to it.

“Can we please swap girlfriends? This is Catherine, and she likes to cuddle late at night.”

Gil lifted an eyebrow. The return address was 14 Michaels Street, and he was just figuring out how he could get rid of the doll, when Catherine strode into the room.

“Hey, Gil, I…Cool! Bubble-wrap.”

Gil positioned himself in front of the door. “Geez, Catherine! Don’t you ever knock?”

She folded her arms and simply stared at him for a moment. “Gil, when have I ever knocked to come into your office?”

“Well, I don’t know…maybe you should start. I could be doing anything in here!”

A slow smirk appeared on her face. “Anything, huh?” She tried to peer around him. “What are you hiding from me?”

“Nothing.”

“Nothing, huh?” She rolled her eyes. “Gil, it’s me. And right now you sound like Lindsey, which is slightly unnerving, so step aside and let me see.”

Gil took a deep breath. “You have to promise not to laugh. Someone left this in my office for me and…”

Unceremoniously, Catherine shoved Gil to the side and was confronted with Blow Up Catherine. Her eyebrows shot up and she looked first at the doll, then at Gil, then at the note. She was desperately trying not to laugh.

“Well, Gil, aren’t you going to introduce me to Catherine?”

He glared at her. “This isn’t funny, Catherine.”

“Oh, come on, Gil.” She turned to him. “You have to admit it’s a little funny. Someone obviously likes you enough to send you a blow up doll.” She walked over and popped one of the bubbles on the wrap. “Plus there’s the added bonus of bubble wrap.”

“I don’t see what one has to do with the…wait…Catherine…what are you doing?”

Catherine started to unwrap the doll, taking off the bubble wrap. “Which Catherine are you talking to?” she asked, as she continued with her task.

“Which…Catherine…”

She giggled and grabbed his scissors.

“What are you going to do now? Cut up the doll? You can’t do that! I have to return this.”

“I like the bubble wrap,” she murmured, slicing off some of the wrapping. “It’s fun to pop.”

“Catherine…”

She chuckled. “Maybe you should rename her. This could become confusing.”

Gil’s eyes narrowed. “Catherine, did you send this…er…”

“Did I send you Catherine? No, Gil, I did not. I’d personally prefer you were having sex with me rather than plastic me.”

“Who would send me a blow-up doll?”

Catherine slipped the bubble wrap into her pocket. “You really have to think about that answer?”

Gil’s eyes widened. “He wouldn’t!”

She walked over to him, putting her arms around his neck and kissing him softly. “Yes, honey, he would.”

Gil put his arms around her waist and kissed her back, long and hard. “Want to work with me tonight?”

She nodded, cuddling close to him. “I’d like that.”

--

The team sat in the break room, listening as Gil handed out assignments. “Warrick, you’ve got a B and E on Henderson. Sara, you and Nick have…”

Pop.

Everyone froze for a moment, and Gil sent Catherine a warning glare out of the corner of his eye. “As I was saying, Sara, you and Nick have a 419 at…”

Pop.

“Does anyone else hear that?” Nick asked.

“Hear what, Nick?” Catherine asked innocently.

“A weird popping noise,” Warrick said. “I hear it too.”

Catherine glanced at Gil. “I don’t hear it. Do you, Grissom?”

He decided she was going to have to pay for this later. “No, Catherine, I don’t. Sara and Nick, here’s your file. Catherine and I will be working a 419 on Fremont. Any questions? No, good. Get to work.” Gil picked up the folder for his case and made his way out of the room.

Catherine lifted an eyebrow and shrugged at the other CSIs, before making her way out to the car. She found Gil already in it, and she slowly hopped in beside him, picking up her water bottle. “So…a 419, huh? Tell me about it.”

Gil turned to her, ready to give her a talking to about the performance in the break room, when he noticed she was sucking on her water bottle. “Oh no. No, no, no. That’s not fair.”

“Excuse me?”

“First the popping, and now the sucking?”

“Okay, so while I have no idea what you’re saying – it sounds dirty.”

“You can’t do that.”

Catherine looked at the water bottle and then at Gil. “What? Hydrate myself?”

“Yes! I mean, no! I mean…” Gil took a deep breath and started the engine. “Let’s just get to the scene.”

--

It was a slow, torturous ride to the scene. Every time Gil looked over at Catherine, she was sucking on the water bottle, and if he was concentrating on driving, there’d be a pop every now and then. Although she was aggravating, it was the teasing look in her eye, the way she sucked on the bottle, or the pop that he knew was coming from close to her body that made him want to throw her down and take her.

Catherine kept looking over at him, an amused smile on her face. She knew that she was making his motor rev, and frankly, she was enjoying it. Besides, it was hardly her fault that she liked to pop bubble wrap and hydrate herself.

Not to mention she loved pushing his buttons.

“Here we are,” Gil said, pulling into a driveway.

Catherine reached over and rested a hand on his arm. “Gil. You know I love you, right?”

He looked at her. “Of course I do. I love you too.”

“I just like teasing you. You’re cute when you’re frustrated.”

He smirked and leant over, kissing her deeply on the lips. His hand slipped into her pants, rubbing her briefly before he moved to get out of the car. “So are you, sweetheart.”

--

Catherine could feel the tingling deep within her every time she looked at Gil, or thought of what he’d done to her in the car. So, naturally, she felt it was fair to have a little revenge.

Anytime he was in her presence, she either sucked on her water bottle, or popped another piece of bubble wrap. She found the bubble wrap most effective, because he didn’t even have to look at her for that one, and it made him jump every time she did it.

“Hey, Cath, check out this blood spatter.” Gil gestured to a pattern on the floor.

She walked over to him, and bent down, instinctively knowing that he was staring at her tush. As she studied the pattern, she quickly popped another bubble and felt Gil jump backwards, and swearing under his breath.

Catherine straightened up and looked at him, lifting an eyebrow in amusement. “Are you alright, Gil?”

“Catherine…” His eyes narrowed in warning.

Knowing him well, she smirked back at him. “Dare you, Gil.”

“To what?” He moved closer. “Take you at a crime scene? Because you’re driving me crazy.”

Catherine smiled and took a step back. “I know you’re ready and raring to go, Master, but,” she ran her hand over his slight bulge, “you’re just going to have to think really innocent thoughts until we get home.” She giggled and headed back to the blood spatter.

Gil took a deep breath and tried thinking of Hodges naked. Yep, that worked.

--

Catherine bent down, swabbing some of the blood off the floor. She turned to Gil. “Can you hand me my water? I need a drink.”

“Sure.” Gil handed it over and watched her take a sip.

“Thanks.” She took another sip and screwed the top back on, licking a droplet of water from her lip as she did so.

His eyes almost popped out of his head at the movement, and he was barely recovering when he realized she was looking at him oddly.

“Gil? What is it?”

“You…” He took a deep breath. “You and the…”

She frowned in confusion and handed the bottle back. “Gil…what the…?”

“You and the water. And the licking. It’s not funny anymore, Catherine. It’s cruel!”

“You think I licked my lip to drive you insane?”

“Yes!”

Catherine folded her arms, giving him a mock-stern glare. “Well, I didn’t. Driving you insane is just a side bonus.”

“I swear, Catherine, when we get home…”

A broad smile lit up her face. “Oh, I’m counting on it.”

--

After they had finished their paperwork on the scene, and Catherine had driven Gil insane with more of her bubble wrap popping, they headed to the car. Gil was about to get in, when he noticed someone in the back seat.

“Catherine?”

She opened her car door. “Mhm?”

“Why is the blow-up doll in the backseat?”

“Didn’t you read the note, Gil? It said she likes to cuddle.”

“Catherine…”

“Come on, Gil. We have to return it.”

Gil got in the car, glancing at her. “We’re not even sure who sent it!”

“I am.” At his curious look, Catherine shrugged. “I checked the employee folders. It’s Greg’s place.”

--

When they arrived at Greg’s, Gil parked the car, ready to go in and blast Greg.

“Wait,” Catherine told him, a smile on her face. “Let me go up. Give me five minutes and then follow me. I have an idea.”

Gil liked the mischievous look in her eyes. “Okay.”

Catherine got out of the car and picked up the dummy. She popped some more bubble wrap, just for the enjoyment of watching Gil squirm. “Meet you up there, bugman.”

--

Greg answered his door and his eyes widened as he saw Catherine standing there with Plastic Catherine beside her. “Uh…hi, Cath!”

“Which one of us are you talking to?” Catherine asked.

Greg gulped. “Uh…you, ma’am. Ah…how did you find…the uh…”

“Plastic Catherine?”

Greg nodded.

Catherine smiled. “Well, the thought that since I’d be the one he was swapping for Plastic Catherine, he should at least introduce me to her.”

“Oh.” Greg squeaked. “Uh, you know it was just a joke, right?”

“Be careful, Greg. You’ll hurt her feelings.”

“Right. So, Grissom…”

Gil peeked around the corner of the door. “Hi, Greg. I appreciate the gesture, but I’d rather keep my model of Catherine rather than yours. But I did bring her back for you.”

Greg’s eyes almost popped out of his head. “You and…oh boy…”

Gil handed over the doll and grabbed Catherine’s hand. “Sorry to drop the doll and run, Greg, but Catherine and I have something we have to do.”

Catherine smiled sweetly at Greg and rolled her eyes at Gil. “Honestly, he’s insatiable. Bye, Greg!”

For a few moments, Greg stood stock still, holding Plastic Catherine in one hand. “I think we need a drink.”

--

Gil gripped hard to the steering wheel. “I’M insatiable? So says the woman who’s been sucking on a water bottle and popping bubble wrap all day. But no, I’m the one who’s insatiable!”

Pop!

Catherine glanced over at him. “You look a little worked up there, Gil.”

Gil gave her a sideways glance. “I swear to god, Catherine Willows, when we get home…”

Pop!

“Are you trying to frighten me?”

“No…just warning you.”

Pop!

Catherine lifted her water bottle to her mouth and sucked on it, making sure the sounds traveled over to Gil’s side of the car.

“Catherine…”

Gil pulled up in their driveway and she just smiled at him.

“I dare you.”

Before he could grab hold of her, Catherine had deftly slipped out of the car and was opening the door of the house. His eyes narrowed and he quickly followed her. Gil opened the door for her and pushed her inside, before slamming the door shut and lifting her against the wall.

Pop!

“No more bubble wrap, Catherine,” he told her roughly.

She smirked at him. “You gotta find it first.”

His hands delved into the pockets of her jeans, widening with shock when he realized the bubble wrap wasn’t there. “You didn’t!”

Catherine looked at him teasingly. “Guess you better keep looking, hadn’t you, Bugman?”

He smirked at her, his fingers unbuttoning her shirt. “I guess I better. Now, is it under here?” Gil was quick to remove her shirt and bra. “Hmm. I think I need a more thorough search.”

Her jaw dropped as his lips descended on her breasts, licking and sucking the tender flesh. His fingers worked on her nipples, bringing them to taut peaks before he took them into his mouth and nibbled lightly with his teeth.

“Oh god…” Catherine closed her eyes, her fingers holding tightly to his head.

Gil lifted his head up, smiling at her. “I think we can be sure it’s not there.” His hands went to the clasp of her pants. “Perhaps it’s down here.”

“You’ll have to look very thoroughly,” Catherine encouraged.

He grinned at her and bent down, first taking off her shoes. Then he unzipped her pants and panties, watching the bubble wrap flutter down to the floor. Gil looked up and lifted an eyebrow. “In your panties?”

A broad smile appeared on her face. “I had to make the hunt fun for both of us, now didn’t I?”

“Oh, I’m having a lot of fun. You?” Gil’s finger ran teasingly down her stomach.

“It’s getting more enjoyable by the second,” she whispered.

“I’m glad to hear it.” His hand cupped her center, delighted when he found her wet and warm for him. “You’ve been looking forward to this, hmm?”

Catherine sent him a look as her fingers caressed the bulge of his erection. “And you haven’t?”

“We’re not talking about me,” Gil replied, undoing his shirt.

“Mhm. Hurry up and get undressed or I’ll go find more bubble wrap.”

“I’m never letting you near bubble wrap again!” Gil took off his shoes and finally undid his pants.

“We’ll see about that,” Catherine replied. Her fingers ran down his arms. “Hurry, Gil.”

He was soon undressed and he lifted her into his arms, pressing her against the wall. Catherine tried to push her body against his, aching for him to be inside her, but Gil continued to tease her, holding her tightly so that she couldn’t force herself down on him.

“Gil! This isn’t fair!”

“Payback’s a bitch, isn’t it?” he whispered into her ear. “You dared me earlier, Catherine…”

She wriggled against him. “I didn’t think you’d do it!”

He chuckled, kissing her deeply. Catherine moaned into the kiss, her arms wrapping around his neck.

“Gil…I…”

With one long thrust he was buried inside her, and Catherine whimpered, her body arching against his. Gil groaned at the sensation of her muscles clenching tightly around him, and his hands held tightly to her body as he started to move.

Catherine’s head rested on his shoulder as he pumped inside her, long and hard strokes that hit every nerve ending inside her body. “I love you,” she whispered, her fingers tightening against his skin.

He smiled, his lips pressing against her skin. “I love you too, Cath.”

She felt her orgasm nearing and she whispered in his ear that she was close, and she wanted him with her. He promised her that he was right behind her and to just let go.

Catherine cried out with pleasure as her release overpowered her, and her fingers gripped tightly to his waist. A few more thrusts and Gil followed her over, groaning her name as he came inside her.

As they slid to the floor, Gil held her body against his, gently caressing her back. Catherine closed her eyes, resting against him.

“Hey, Gil?”

“Yes, sweetheart?”

“Got any more bubble wrap laying around?”
