Catherine and Lou had been making the most their day off, it was even more of a luxury that they both had the same day off together. They had been out shopping and Lou had seemed preoccupied, Catherine hadn't been able to put her finger on what it was that had his attention but considering how happy he appeared she wasn't unduly worried. She presumed it was the fact that he was going to be a father.

They had wandered through a maze of shops and pretty little boutiques, Catherine found it amuzing that Lou loved shopping as much as she did. Catherine had bought a new cd that Lindsey had reccomended to her. It was not a new cd as such it had been out for a while but she'd never thought about listening to the Pussy Cat Dolls, her daughter had played it one night during a lengthly phone conversation.

She wanted to somehow go into a particular shop without Lou being with her but how was she going to do that with him being so preoccupied.

Little did she know Lou was pondering how to get rid of her, at least temporarily. Lou knew exactly which store he wanted to go into but there was no way he could contemplate such a bold move with Catherine right next to him.

There lives were so complete Catherine was by now eight weeks pregnant and looked absolutely radiant, Lou doted on her every waking moment making sure she had anything and everything that she could possibly want or need. That was the reason for this shopping trip he wanted to spoil her, well it was part of the reason.

"Baby? do you mind if i dissapear to the ladies room?" Catherine lied, pointing to a nearby cafe.

"Sure thing honey, I want to check out that new gadget shop across the street" Lou wondered if his lie was convincing enough.

And with that they both went their seperate ways once Catherine was sure Lou was out of sight she darted back out of the cafe and into a designer lingerie boutique. Wether it was the pregnancy, her renewed self confidence, her love for Lou or a combination of the three Catherine felt mischieviously cheeky. So much so that she had decided to splash out on some La Perla underwear, that she knew would have quite an effect on the sexy homicide detective.

The store was full of so many different fabrics, styles, designs and colours you name it they had it. This time though it had to be very special she wanted something out of this world, something that would truly nock his socks off.

"Hi there, can i help you?" a young store assistant asked.

"Yes, im looking for something extra special" Catherine replied a smile curving her lips.

"Is there a special occasion?" the young assistant replied.

"Im two months pregnant, feeling great and want to give my partner a surprise" Catherine added.

"Seriously? You look great no-one would even know unless you said. How do you stay in such great shape?" The shop assitant asked curiously.

"I used to be an exoctic dancer before i became a csi. So i've traded dancing for chasing criminals." She laughed.

"So im guessing you're going to give you're partner a special performance then?" the assitant knew from conversations with her friends that an exotic dancers' outfit had to be just right.

"Yes I am, he knows i used to be a dancer it got brought up at work during one particular case."

"Your partner is a cop?"

"Yep certainly is" Cath smiled remembering the first time she laid eyes on him.

"Well in that case i have just the thing"

Lou had waited until he was sure Catherine wasn't around before he headed in the direction of a jewellers that he had spotted a while ago. He'd been contemplating this very important idea for sometime, knowing it was his dream but at the same time hoping it would be what Catherine wanted as well.

He been nervous as hell these past few weeks, trying to get a chance to look at Catherine's jewellery collection so he'd know what size to get. The chance had arisen about a week previously when Catherine wanted to get some of her jewellery polished. Lou had kindly offered to take it in for her, Catherine had said it wasn't a problem taking it in herself but Lou had insisted it was know trouble adding that he was going out to meet his brother so could drop her jewellery off on route.

Walking inside the jewellers he suddenly felt way out of his depth, how was he going to chose the right ring. It couldn't be just any ring it needed to be just as perfect as the person who's hand it would hopefully end up on.

"May i help you sir?" The manager asked.

"Yeah...I um, I'm looking for a ring." Lou felt like a child again.

"An engagement ring?" The store manager suspected he already knew the answer but decided to ask anyway.

"Yes, my girlfriend and I are expecting our first baby." Lou smiled.

"Congratulations! How long have the two of you been together?"

"A year and a half, we met at work" Lou beamed even more remembering the first time he laid eyes on Catherine.

"Wow not many couples manage working together as well, you must have a strong bond." The manager said.

"We do yes, we met during a murder case. Catherine is a csi and im a homicide detective for lvpd."

"Do you have a budget in mind?" the manager asked bluntly, after all he needed to know so he could help Lou choose.

"Money isn't a problem, I don't care what it costs so long as it's the perfect ring."

Within ten minutes of searching Lou had indeed found the perfect ring, a three carat emerald cut diamond. It may have cost $10,000 but Lou didn't care. It was perfect and so was Catherine. As he left the store and began hurrying back to where he had left Catherine he just prayed it would be worthwhile and that she would give him the answer he so desperately wanted to hear.

Catherine was already waiting outside the cafe that they had agreed to meet back up at when she saw Lou walking towards her. He looked slightly less preoccupied than he had done but still seemed to be a million miles away.

"Hey baby, did you find anything in that gadget store you liked?" Catherine asked sweetly.

"No not really, you didn't throw up in the ladies room did you honey? " His tone soft.

"Nope i didn't im all good" She smiled a mischievous grin on her beautiful face.

"That's good, how about we head home?" He said wrapping an arm protectively around Catherine's shoulder.

"Perfect i was thinking why don't i cook dinner for us then i have a bit of a treat for you". Her grin widening.

"Mmm i like the sound of that".

Arriving home Lou went up to their bedroom as Catherine went into the kitchen to start preparing their dinner. She put the oven on to pre-heat and took out the ingriedients that she had prepared earlier. Knowing that she had time she took her shopping upstairs and was relieved when she heard Lou opening the shower door and switching it on.

She took out her new lingerie and layed it out on the bed, gazing at it she wondered was the sexy detective would do the moment he saw her in it. She smiled imagining what he would do when he saw her dance in it.

She removed all of her clothes and took the tags of her pricy negliche. Satisfied that it fitted her to perfection she put on her silk robe and went down stairs, heading back into the kitchen she placed their meal into the oven and set the timer.

Next she went over to the stereo and put in the new pcd album, hearing the shower turn off and Lou's footsteps on the stairs she cranked up the volume and selected the perfect track.

Lou felt totally relaxed after his shower, stepping out he wrapped a towel around his waist and proceeded to go downstairs but as he reached the half way point of their staircase he heard some very sexy music. The Pussy Cat Dolls song 'Buttons', as he got closer and closer to the final step he saw her beautiful legs.

"Catherine?" He asked as she dissapeared from his sight.

"Sit on the sofa" Her voice demanding but sexy.

He stepped into the lounge and then he saw her fully, her silk robe hugging her body like a glove. He swallowed hard, her hair glistening and make up applied with precision. Catherine looked directly into his eyes as she untied the belt and let the robe fall at her feet.

Catherine was wearing the most undeniably scorching hot dark red sating bra and matching panties with a black satin trim around it's edges it complimented her thigh highs perfectly and with a pair of killer heels to boot he was completely at her mercy.

Catherine ran her hands down her abdomen and over her hips, sliding them down the fronts of her thighs. Her hands touched together in the middle as she moved them back up, and let her hands cup her breasts from underneath. She lifted them up slightly as she pressed them together, her nipples hardening instantly. Catherine let her fingertips lazily glide across them as she lifted her arms, letting her hands move over her neck. They met at the back, lifting up her hair. Holding it with one hand, the other moved to the wall, her hand flat against it. The song ringing in her ears she began swaying her hips.

Her other hand lowered down, and touched against the wall behind her also. She ground her backside against the door, moving her hips all the while. Then she lowered herself and bent her knees, and swooped down, first to one side then the other, rolling her backside against the wall the whole time. Catherine's head fell back, exposing the sweet spot on her throat, and Lou watched her pulse throb in the delicate skin. Catherine's eyes were shut, and when she rolled her head back around they opened, meeting Lou's gaze full on. Her lips parted and she licked her lips provocatively.

Catherine pushed herself off the wall and spun around, pressing her cleavage against it. Her arms rose straight up above her head, her hands flat on the wall, her hips still swinging out to the rhythm of the song. Her hips started moving more in a fevourish pattern, and as they did she slid her hands down the wall ever so slowly. Once they were at her waist , she braced herself on the wall and pressed her pelvis into it, letting her head drop back, and swayed from side to side. She moved her knees and bucked her hips against the wall, finally spinning back to the side Catherine and Lou's eyes finally meeting again.

Catherine bit her bottom lip between her teeth and finally her hips stopped. She stood with her legs spread wide her shoulder blades pushing into the wall. she tilted her pelvis out in a most enticing way.

Lou had watched the show from the sofa, and it took every drop of restraint not to rush to her, yank her panties down and wrap her legs around his waist while he fucked her hard against the wall.

Catherine was breathless and highly aroused. This was the first time in years she had done this. But by the look in Lou's eye, he had loved every second of it. She could see the bulge through the white towel, and had seen the muscles in his body tense up, as if he was desperately holding himself back. God, Catherine wanted him. She curled her finger and seductively motioned for him to come closer. Lou was up and on his feet in a flash. He stopped in front of her, and she turned so her back was to him.

Lou leaned down and kissed her shoulder, his hands lightly holding her waist. She backed up into him and started moving her hips yet again. The soft fabric of his towel rubbed against her upper thighs and the lower part of her but cheeks. Catherine leaned forward, and Lou's hands moved to her back, his fingers grazing down either side of her spine. Lou's thumbs pushed in gently, touching each vertebrae, going all the way down to the base of her spine, then back up. Lou rocked his hips forward, not being able to restrain himself. Catherine dipped her knees and then straightened them, rubbing her backside up and down along the front of his body, feeling his cock strain under the material. Deciding it was in the way she yanked it off so he was buck naked.

Lou reached a hand around the front of her, his fingers spread out over her lower stomach. The tips just only reached the top of her centre. Lou left it there like that just to tease for a moment as she kept her hips swaying. Lou's other hand grasped her hip and he slowed her down, then started thrusting against her. She was bent over just far enough she could almost feel him where she needed him.

Lou's hand dipped lower, and he pushed his middle finger upwards. It slid easily between her lips. Catherine was wet for him very wet for him. Lou's finger started a slow steady rhythm, rubbing upwards and down over her clit. Catherine gasped aloud. Lou his eyes close and allowed himself to enjoy all the sensations at once.

Lou let his fingertips slide up and down her clit, then finally he pushed in, again slipping into her depths easily. Catherine bit her lip to keep from moaning. She bucked her hips, allowing him greater access. two fingers dipped into her wetness, and Catherine's knees almost buckled underneath her. She was so aroused she wondered if she was going to make it. Lou's fingers never stilled in their pace, just softly stroking and twisting. Lou felt her juices covering his hand, and now it was his turn to try and hold back a moan. Catherine's muscles contracted around his finger, trying to pull him in deeper. When Catherine was at the point of no return, Lou pulled away from her. Catherine groaned at the loss of contact and Lou stepped away from her. Catherine very nearly fell over and whacked her head on a nearby cabinet. She didn't realize how much Lou was been holding her up.

"That was a mean trick." Catherine gave him a small grin.

"I know and as much as i want to continue this i have something to talk to you about" Lou felt the nerves creeping back in.

Catherine wrapped her robe around her and so did Lou, He reached into his jacket pocket and pulled a small package out of it.

"Catherine, there's something i need to ask you!"

Sorry to leave it there but i have writers cramp.
