Anyway enjoy and please read and review!

Summer Heat

Chapter 1- Bit Seedy, really.

Donald Flack Jr. had been out of hospital a couple of months now and had been on desk duty for a month now. He was bored. He truly was, there was only so much paperwork he could do and so many 'gentle' suspects he could interrogate. It didn't help with his best friend Danny Messer telling him about cases he got to work on, he knew he was just trying to help but Danny could be a bit blunt sometimes.

Flack was pretty embarrassed about his current condition, as he was still pretty weak. As much as he hated to say he was. He still moved with a slight limp and though he could run quickly again, just not as fast as he used it, that would still take time and that was something else he hated. He like to move about and keep on his toes, it was second nature for a cop. Especially when everyone at the precinct kept casting sympathetic glances towards him.

He had stopped going to physical therapy a fortnight ago pleased when his therapist said it was one of the quickest recoveries they had ever seen, given the amount of damage done to his body. He had advised Flack to see a counsellor or shrink or someone to help him through the emotional effects of the attack, but Flack refused saying he was too busy. Truthfully though, he was too scared, but the scariest thing was that he couldn't really remember what happened to him. He could see flashbacks here and there but he couldn't remember the whole thing and that really bothered him. So he decided to get out of his apartment and clear his head.

So here he stood at the counter of a dead beat bar close to his home. The summer heat of New York City had reached it's peak according to all the young weather girls all over the TV's. Needing to get out and have some normality, Flack downed the last of his drink, water again by his doctors orders, and looked around the pub. He only came here occasionally, it wasn't the one the gang usually came to. 'Sullivans' was their joint, it was practically owned by the NYPD and they were friendly with all the locals. Searching the pub, his ignored all the young girls fawning around him, hoping to catch his eye and instead focused on the woman who was centre of attention on the dance floor.

Aiden Burn.

It was no secret in the Crime Scene Investigations office that Flack liked Aiden. He had developed a crush on her since seeing her almost three years ago now, and despite flirting with many women and have no trouble in getting dates, he didn't have the courage to ask her out. Danny had tried forcing them together, but that didn't work. So he had just let Flack do it in his own time.

As Flack peered closely at Aiden he saw she had gotten a follower who was begging to buy her a drink as she made her way to the bar. Before the man could sit next to her, Flack intercepted and plonked down in the only available seat next to her.

"Hey man I was-" But other guy stopped short when Flack flashed his shield. He then just blended into the crowd. It was only then that Aiden noticed Flack next to her.

"Flack, hey. I didn't know you were here."

"Just needed a drink and some fresh air, seemed like an alright place."

"Bit seedy really." Aiden admitted. Looking around, she noticed a lot of guys looking at her. But she was used to this, even at crime scenes when respect was meant to be shown to the victims, she had seen cops checking out her ass. Desperate as he was to do so, Flack had never done that, knowing she hated it. He could be a gentleman sometimes.

"Wanna go for a walk then?" Flack asked. Aiden shot a grateful smile and grabbed his hand, practically dragging him out the bar. Once on the street, Aiden felt the humid air on her face.

"At least the bar was air conditioned." She said, as the pair began walking, Aiden noticed Flack's slight limp which didn't really hinder him but was still noticeable, she thought it better not to say anything.

"I know. Every station on TV is saying this is gonna be the hottest Summer the city's ever had. But then again, they always say that."

"More work for us it means. People get more agitated because of the heat." Aiden supplied. "Yesterday I practically had a guy who had drowned in his own sweat."

Flack laughed as Aiden recalled the crime scene from the previous day. Though he felt left out, he liked listening to Aiden talk about the job. In their line of work, they did see a few unnatural things that not many would want to see. But it's what they did.

The pair walked in silence down the unusually quiet New York street. Stealing glances at her co-worker and secret crush, Aiden smiled to herself. She had loved it when Flack got his hair cut, which in her opinion and many other girls around the Lab, made him look even sexier. According to the criminals, it made him look even more intimidating. Aiden smiled, though she had seen Flack angry when interrogating suspects and even physically violent towards them, she knew really he was a sweetie, loved his friends and wouldn't dare hurt anyone he cared about.

So why did he not tell her how he felt?

She knew he liked her. Hell everyone knew. Plus he always seemed to have this air of confidence surrounding him, which Aiden was jealous of. He always seemed to sure of himself and had no trouble with anything. It seemed. Though she was a CSI and there were few female ones, she had been taught by her mother, the guy was meant to make the first move. So she just waited.

Looking again, she noticed how gorgeous his deep, sparkling blue eyes looked in the New York night and his sexy smirk, and the fact that he just gave off this feeling of confidence. She really did love him, why couldn't he just say it out loud, then she gladly would.

What Aiden didn't notice was that while she was checking Flack out, he was doing that exact same thing to her. Looking at her typical Brooklyn beauty, with her long, wavy black hair, her sexy body and charming smile. He knew she was a tough girl who could take care of herself, but he also knew she could be a soft touch at heart, he had seen it many a times.

Just as they got to Flack's apartment building, he saw some kids running towards them, obviously drunk and just having some harmless fun or so he thought.

As they came closer, Aiden was staring at Flack and didn't notice them, not till it was too late. One of the kids accidentally pushed her down to the ground quite forcefully but continued on, muttering sorry, chasing his mate.

"Hey you little punk!" Flack called but knew it was no good, the kid hadn't done anything too bad. He knelt down to Aiden and noticed a nasty cut on her shoulder, she had fallen on some broken glass and the blood was seeping through to her top.

She winced and sat up, getting a little glass in her palms as well.

"Easy, easy now." Flack said helping her stand up.

"Don't worry we've both had worse." She said pointedly. "Just need to get cleaned up."

"Well come on then, we're at my place. We'll have you bandaged in no time." Aiden smiled as Flack led her to his apartment.

Soon enough, they arrived at Flack's home and while she settled onto the sofa he grabbed the first aid box from the bathroom. As Flack looked at her back, he noticed her top was getting in the way of the cut. 'Great, this'll be fun.' Flack thought sarcastically.

"Um, Aiden. You're top's in the way, you'll need to take it off. I've got a spare shirt you can wear after."

"Right, OK." Aiden said nervously. Seeing she was uncomfortable. Flack gave her some privacy and fetched her a glass of water as she undressed. Coming back into the front room, carrying her drink, he noticed she was on the sofa, clutching her top to her chest, and had her bare back exposed.

Swallowing hard, Flack handed her the drink, got out peroxide and began cleaning the wound. He heard her wince as he dabbed it on, but she didn't complain. Quickly as he could, he had it bandaged and finished.

"All done." He smiled.

"Thanks."

"I'll just get you that shirt." Rushing quickly to his room, before she could notice how excited he was, he didn't notice Aiden follow him to his bedroom.

As he rummaged around in his wardrobe, Aiden stood in the doorway, still clutching her top, watching him, a small smile on her face.

"Flack?" He turned quickly, and saw her standing there in surprise.

"Yeah, it's here somewhere."

"Flack forget about the shirt." She said, sitting on his bed. He seemed quite nervous about how comfortable she was to just come in his room.

"Why?"

"You like me, don't you?"

"Ww-wh- what makes you say that?" He stuttered to her amusement.

"Kinda obvious."

He blushed and looked down. But then thought about it. He stared questioningly at her.

"Why are you asking me?"

Aiden shrugged and walked over to him. "Because I like you too."

Flack stared and instinctively grabbed her and pulled her towards him, kissing her full on. As Aiden opened her mouth, Flack forced his tongue in her mouth and battled with her's. Both knew there was no turning back now, and neither were disappointed by that fact.

But still Flack had to be sure, he still wanted to give her a chance if she wanted.

He pulled apart and looked her straight in the eye. "Aiden you absolutely sure about this?"

"Definitely." She replied. That was all Flack needed to hear.

With that, he picked her up and took her to his bed. As soon as she settled down, kneeling on the sheets, she let her top fall away, leaving him staring at her flawless chest, Flack almost came right then. She began pulling his shirt off and tossed it into the corner. As Flack's hands roamed her body, she entangled her own in his hair. Kissing him roughly on the mouth. He took his head away and kissed her down her neck to her collarbone, tasting this beautiful woman he could now call his. As his hands lowered themselves down her body, he felt her ass and realised she didn't have any panties on at all.

"Are you-you not wearing any underwear?" He asked in disbelief.

"Too hot for that kind of thing." Aiden grinned wickedly at him. Flack smiled and felt himself blushing. Aiden saw and sat on the edge of the bed, with Flack standing between her legs. She unbuckled his belt and undid his pants, her heart beating wildly. Sure she had seen him naked that time at the hospital and had fantasies about him ever since but this was different, she pulled his pants down to the ground and stared in awe at him. Flack had his eyes clenched in pleasure and was biting his lip. He felt himself losing control more and more and decided enough was enough. He had to be inside her now.

As Aiden began to slowly and agonisingly stroke him, Flack forced his hands to find her began caressing her. But he kept control and continued staring his lover. Now completely naked, Flack could see Aiden was the most beautiful woman he had ever seen and was grateful to get a chance to see her like this, knowing he was the only one to. Smiling at her full of love, he slowly entered her.

It was slightly painful, as Flack's chest and stomach ached. But he progressed, knowing Aiden was worth it. Aiden noticed the huge scar across his stomach and tried to be gentle, she could see the other scars and bruises on his body, and smiled at him.

The rest of the night was full of passion and heat for the young lovers. As the morning came so did sleep and they fell asleep in each other's arms. With Flack recalling how Aiden had called his name when she came, and Aiden remembering the smoothness and heat of Flack's touch as he climaxed. Both knew this was for keeps, and nothing could change that.
