Castiel says he likes blonde hair, dean takes this to heart and does something about it; to positive results

"How is it that you change your hair colour, Dean?"Castiel asked as he cocked his head to the side in his 'confused stance'. The hunter looked at the brunette with a heavy frown.

"What are ya talkin' about Cas? I don't change my hair colour at all." Dean replied running a hand through his hair self-consciously.

"Well, a few months ago your hair became paler, but now it has gone darker again. So what do you do to make it do that?" Castiel explained with his head now back to its normal angle.

"Oh, that was because of the sun, it bleaches already pale hair and makes it go blonde I guess." Dean pondered, watching as the angel nodded and turned to look out of the motel room window into the dingy street.

Dean decided that the conversation was over and sat on the edge of his bed, rolling his stiff shoulders and closing his eyes as he let a long sigh escape his lips.

"I liked your hair when it was turned pale by the sun, it suited you. It highlighted your tan and made your green eyes look brighter." Castiel said in an almost-whisper, Dean whipped his head up to question the angel's statement, but with a flutter of feathers Castiel was gone from the room, leaving Dean reeling just a little bit.

Dean started to pace the motel room, going over it in his head; the way Castiel looked at him from time to time, like he was searching his soul and screaming out for him; the way he would make comments like that all nonchalant and then flutter away without ever bringing it up again; the way he would compliment him and defend him if someone was on the warpath. It wasn't like he did those things to Sam or Bobby or any of the other hunters they worked with; just Dean getting the special treatment.

Over the time he had known Cas Dean had let him down a fair few times, caused his faith in him to waver or tested everything the angel thought he knew about the world. So it really didn't make much sense why Castiel would suddenly start warming up to him and being all friendly, not that Dean minded. He liked being in the angel's good books for once, but at times it was a little awkward, Cas would say something in his deep gravelly voice that would have so fricking many innuendos and suggestions within it that it would have Dean blushing. And it took a lot to make the elder Winchester blush so that really was saying something.

He wasn't blushing at the actual content, no, he had been on the receiving end of dirty talk practically from the moment his downstairs brain kicked into life at age 15 or so. He was blushing because of the context of the suggestions, if they were in the bedroom wrapped around each other after fucking, or just about to fuck then it wouldn't have mattered one bit. And hell! That was one beautiful fantasy that Dean locked away as 'possibly inappropriate for the moment, revise later while jerking off in the shower'. But for Castiel to say those things, laced with an emotion Dean couldn't quite place and sounding so innocent falling from the angel's lips, in the middle of Bobby's front room while he and Sam were doing research was downright awkward, for all of the men.

Thankfully the latest episode in the 'awkwardly truthful admissions' chronicles it had been just him and Castiel in the motel room. Sam and Bobby had gone off to visit one of their victim's uncles to dish some dirt on the demonic possession case they were working on. The uncle lived 4 states over so their trip would take a couple of days, leaving dean alone to research the whereabouts of the suspected possessed person. While the person he was snaking had been on a crazy killing spree the last week, her activity had died down to practically nothing; this was either a good thing or an incredibly ominous one. Knowing the Winchester luck it was probably chillingly ominous and there would be another attack any day. Meanwhile Dean was bored and more than a little freaked about what Cas had said about his hair being blonde and the angel preferring it.

Well, he wasn't freaked out per say, more spurred on by it. Or turned on by it, he couldn't really tell at this point. All he knew was that his feet were carrying him to the seven eleven a few blocks away with the intention of buying some blonde hair dye. If this weird hair preference thing was going to be the thing that finally snagged Castiel, and would cause him to be jumped by the uptight angel then it might be the best thing to happen to Dean in, like, ever.

Dean found himself coming to terms with his feelings towards the angel quite easily. After a few freak outs about his latent homosexuality that he tried to solve by sleeping with a lot of hot women (well more than normal) and a few moments of sitting completely dumbfounded that the word feelings hadn't sent his player brain screeching and running to the hills, he'd come to terms with it. He wanted Castiel. Fuck, he needed Castiel, and soon. He liked him, he found him funny and cute and so-innocent-it-hurt-sometimes, but then he suspected that Cas had a dark side full of humour and lust and oh dear god! What Dean would give to uncover that side of his angel!

He'd taken a while to distinguish between wanting to fuck the angel into the mattress, and wanting to kiss him and grope him and suck him and lick him and yeah all of that primal stuff, and the loving stuff of wanting to hold him and teach him about love and companionship and relationships and eternity and sacrifice and all that chick-flick-moment element. But he'd gotten there, it was only last week, but he was definitely in romantic-love-you-forever-marry-you-just-being-with-you-makes-my heart-swell territory now. And it was like everything he had always been against (monogamy, commitment, honesty, love that really really meant something) was becoming more and more attractive to him, all because with castiel he could see it all making sense. And jesus Christ it was weird to think that dean fucking Winchester, sex extraordinaire and eternal fuck buddy of the beautiful girl, was even thinking about settling down.

The fact that Castiel was a man didn't really bother him either, in his long and drawn out sex life dean had experimented with boys, never gone as far as fucking them, but got pretty darn close a few times. It could never be said that dean didn't know his way around a dick as well as he did his own, and while not many were aware of his sexcapades with the male gender, they stood out as some of the greatest fumblings he'd ever had (not including bedding twins or talking his way into the pants of actresses and models and cheerleaders-only legal ones of course). So the male thing didn't' really factor into his musings about the angel. Besides the body Castiel was using was a human one, so there would be no star-trek-esque surprises like ribbed penises or hidden multiple limbs underneath the huffy accountant clothes Castiel wore.

He was broken from his thoughts by a bell chiming as he walked through the door to the store. He moved quickly to the cosmetics and hair aisle and scoured around for a blonde hair dye for men. He eventually found one and purchased it, gaining a questioning look from the cashier which he tried to ignore. He felt that explaining his crazy reasoning to the nerd with thick rimmed glasses and a plaid shirt buttoned to the top might make it sound stupid and foolish and dean might lose his nerve. So he handed the money over and walked out without another word.

Once he got back to the motel he went straight to the bathroom, grabbing a hoodie on his way in so he could cover his head if anything went wrong, the last thing he needed was to fuck it all up and then it might turn green or something and Cas would hate it and Sam would take the piss out of him for the rest of his life. He removed his shirt and his t-shirt and took the hair dye out of its box sitting on the toilet seat to read the instructions, as he and Sam hadn't had a normal teen-hood they hadn't really had much chance to experiment with dying their hair crazy colours or wearing weird fashions. They had a job to do and they could hardly scare monsters away if they had blue hair and were wearing low rider jeans and neck chokers and shit.

After reading it through twice and pulling the latex gloves on that were in the box he began to mix up the colour in the bottle, pouring the actual blonde colour into the bigger bottle dean shook it vigorously. He watched as the solution turned a golden orange colour and blanched a little; he really didn't want to have ginger highlights rather than blonde ones. But the instructions said it was supposed to be orange so he went with it, he shoved the lid back on and moved towards the sink, looking at himself in the mirror as he lifted the bottle above his head and squirted some onto his caramel spikes and ran his fingers through it to make it evenly spread. It didn't seem to be doing that much but it did say in the instructions it would take an hour or so. So dean continued to apply the colour to his hair just enough to highlight the tips. But then he felt the cap of the bottle wobble and fall off, leaving the dye pouring onto the middle of his head, like the whole bottle. Fuck fuck and double fuck! He thought 'what the hell' and spread the colour around, coating the untouched natural hair with it until all of his head was covered in the stuff rather than just the middle. Why did this shit always happen to him?

Once it started to go to work dean sat back on the toilet seat and removed the gloves, glaring at the now empty bottle that lay discarded in the sink. Castiel had said he liked the blonder hair; maybe this new style might please him even more than the highlights would have? Dean really hoped so.

After the hour of waiting was up dean leaned over the shower and washed the dye from his head, grabbing a towel and dabbing it away from his forehead, enjoying the way the heat that had erupted from the colouring had cooled down now. He stood in front of the mirror and turned his head left and right. Yeah that was one hell of a blonde colour.

Dean grabbed the hoodie and pulled it on, lifting the hood so it covered his shock of blonde hair. He trudged out of the bathroom and grabbed a beer from the fridge, sitting back on the bed and wondering what to do.

He wanted to see Castiel and talk to him because he loved talking to him; the angel had interesting perspectives on things, especially in his ethereal separate-from-humans position. And of course Castiel was very nice to look at, with his bright blue eyes and his pink lips and his high cheekbones. His dark hair all ruffled-looking like he's just had sex and someone had been running their fingers through it roughly. Dean had it really bad; he wanted castiel's eyes to lock with his, his lips to connect with his own, and he wanted to lick his way up those cheekbones of his. He wanted to be the one who got to run his fingers through the angel's hair while kissing the lips off him, while fucking him into the mattress, or just while watching crappy TV in a cute and domestic way. Dean had never been a fan of domesticity, he couldn't ever imagine liking it, but when he thought about Castiel and himself in that environment he could admit that it warmed his heart a little. If he was ever going to settle down he could see him doing it with Castiel.

Just as that thought crossed his mind he heard the tell-tale flutter of wings as Castiel landed in the middle of the room. Dean jumped a little bit at the sudden arrival, and unconsciously pulled his hood further forwards to cover the stupid blonde hair.

Castiel whirled around to face him and a small smile came to his lips. Dean raised his eyebrows in a silent question.

"You were thinking about requiring me for something, so I came here to see you." Castiel said in a calm voice.

"You were reading my thoughts?" Dean asked, blushing slightly at the thought of the angel knowing what was swirling around his head. Castiel shook his head.

"No, I am not permitted to read your direct thoughts unless given allowance from you. I just picked up on the general gist of them; 'want to see you'." He explained, moving a little closer to where Dean was sitting.

"Oh right, cool." Dean said in the most nonchalant voice he could manage.

"So what did you want me for? Why do you need me?" Castiel asked, his eyes boring holes through Dean as he asked this question. What did he want castiel for? Why did he need him? Dean was glad the angel couldn't read his thoughts as they sank into the gutter thinking about answers to those questions.

"I just wanted to hang out with you; Sammy and bobby are away and I've got nothing to do here but wait for them to come back. Is that okay?" Dean said after dragging his mind back from the depths of porn it had strayed to.

Castiel nodded and smiled his almost-smile again. Dean got up to get a beer for the angel, assuming that he would want to relax a little bit. He placed the beer on the table and smiled his winning smile back to Castiel.

"I have never seen you wearing a garment like this before, why are you covering your head? Have you injured yourself?" the angel said after accepting the bottle from dean and moving to stand in front of him.

"Not injured, I just felt like wearing it, my hair is a bit weird today." Dean replied honestly leveling Cas with a stare. The angel raised his hand and pushed the hood away from dean's head, his eyes frozen on the blonde locks that appeared.

"Look, I know it looks terrible, I tried to highlight it blonde because you said that you-

Dean stopped talking mid sentence as he felt long soft fingers cording through his hair and down the back of his neck.

Before Dean could make some smart ass remark, raise an eyebrow or mention the personal space agreement the angel surged forward and pressed his lips to dean's. Without waiting for it to be returned or for dean's brain to reboot after the short circuit Cas wrapped his arms around Dean's neck and licked at the seam of Dean's lips pleading for entrance. Dean finally did manage to gain control and spread his lips and started to participate. Castiel pushed his body into Dean's, making sure they were touching from chest to hip and lower. With the force of the kissing and embracing Dean was pushed backwards into the wall, where the angel proceeded to spread his legs with a knee and grind their hardening dicks together causing Dean to moan in welcome surprise.

Those fingers were back in his hair again, gliding through the blonde spikes with practiced ease.

But then the action stopped, the angel froze in his arms and blushed dark pink, disentangling from the hunter and taking a few steps back. The look on Castiel's face could only be described as utter embarrassment and mortification.

He had been overtaken by a wave of lust at seeing the blonde hair and acted on it without thinking. Now he had ruined his friendship with Dean and wouldn't be able to look him in the eye again. Before the angel could continue berating himself within his mind, which dean knew of because of the look on his angel's pretty face, the blonde stepped forwards and caught Castiel's hands in his, pulling him closer so they were a few inches apart. He ran a hand up Castiel's trench coat-covered sleeve and over his shoulder, cupping the brunette's jaw and smiling a genuine smile down at him.

"so, you liked the blonde hair then?" dean joked, rubbing a thumb over Castiel's cheekbone as the angel looked down at the floor, still feeling guilty about kissing his friend.

"Dean…I…I do not know what came over me…I'm sorry." The angel replied, ignoring dean's comment in favour of apologizing to him and putting across his anxiety at the loss of their friendship.

"Nah uh, mister. You don't kiss people like that and turn them into jelly on the floor and then apologise for it. Fuck that was hot." Dean said in his sexy voice, smirking at the brunette as he watched a few different emotions skitter across his face; confusion, uncertainty, disbelief and then hopefulness. While dean could be tactless and completely oblivious some of the time, but Castiel he could read like a book.

"You appreciate my actions? You are not horrified by them?" the angel clarified, lifting his blue stormy eyes from the ground to finally lock gazes with Dean. The hunter's shake of the head had the tension and fear within Castiel releasing and unclenching.

"Hell no. nothing that hot could horrify me." dean said, grinning widely as he continued stroking Cas' cheek fondly.

"So you would not complain if there were to be a repeat performance of my actions?" Castiel said, all the worry in his voice extinguished and replaced by a seductive tone dean had never heard him use before. And fuck if that wasn't the hottest thing since ever.

"Not in the slightest, the only complaining I'd be doing was you getting me all horny and then not doing anything about it. C'mere angel boy." Dean joked, closing the distance between them and kissing the angel again, full on the mouth with tongues exploring teeth and hands running up and down each other's backs. Before it could get too involved Sam walked into the motel room and yelped at what he saw; his brother and his angel friend necking right in the middle of the room.

The elder hunter and the angel broke apart at the sound and whipped around to see Sam standing there with a stricken expression on his face. However the horror turned to laughter as Sam caught sight of dean's weird looking blonde hair. He threw his head back laughing raucously as Dean blushed.

"Not a word Sammy. Besides I've discovered that blondes have more fun."Dean said, punctuating his words by sliding his hand down Castiel's back and groping his ass. The angel leapt forwards away from the questing fingers, but couldn't keep the grin from his usually-serious face.

"So much more than I ever needed to know, Dean. If you're going to be getting up to that sort of thing I'll get a separate room. Feel free to explore with my newly-blonde brother all you like, but AFTER I've left the room, okay?" Sam replied, wrinkling his nose at them, watching Castiel curl into Dean's side and nuzzle at his brother's shoulder, while Dean leant his head against Castiel's smiling like a sappy girl. Maybe he could permit the chick-flick moments for his Castiel? Yeah he decided that would be okay.

"Sure thing, Sammy. You might wanna book a room a few away from ours though; because soon enough we're gonna be making some serious happy noises, know what I'm saying?" Dean assured with a suggestive wiggle of his eyebrows. Castiel blushed a little bit as Sam rolled his eyes.

"Subtle as a brick, Dean. And again, I don't wanna know, man. Oh, and do I have to give Cas the 'concerned brother threatening to kill new boyfriend if he hurts you' speech or is that kind of redundant here?" Sam said as he retrieved his laptop from the nightstand and looked between the other two.

"I think he's got the gist of it, thanks Sam. and you have to update me about what you found out on your road trip with bobby over breakfast tomorrow." Dean replied, running his hand up and down Castiel's back smoothly.

Sam nodded and walked out of the room, leaving Castiel and Dean alone again. They surged together in another deep kiss, this time Castiel was the one to be groping ass, not that dean minded at all. When they broke apart Castiel reached up and ran his hand through Dean's blonde hair again.

"I love you Dean Winchester. And don't worry about Sam laughing at your hair, because I think it's completely sexy and I almost came in my pants when I first saw it." The angel said without a hint of irony or embarrassment, before turning and walking towards one of the beds.

Castiel had managed to break Dean's brain again, he stood there with his jaw dropped and his eyes bugged for a few minutes, trying to configure his innocent angel actually saying that.

"Dean, are you coming to bed, or are you going to leave me here alone?" dean heard the brunette say from behind him, snapping out of his trance he raced over to the bed and straddled Castiel's slim hips, wiggling until he felt the angel's erection stirring to life beneath him.

"I have no intention of leaving you alone when you're all hard and ready for me. Oh, and Cas?" Dean said, while he scattered little kisses over Castiel's lips and neck and Adam's apple and collar bone.

"Mm?" the angel replied, his head thrown back and his hips bucking up involuntarily.

"I love you too." Were the last coherent words spoken into the room before their coherent vocabulary deteriorated into moans and groans and whimpers before calling their names in unison as they climaxed together.

I hope this was okay; this is my first supernatural fic so I hope I didn't screw up spectacularly.

I think this is set in series 4 where dean and Castiel sort of like each other, or maybe series 5 but there was a lot of angsting going on most of the time so I'm not really sure when it's set.

I dodged out of writing the actual sex scene for this one, but I might post a second chapter if anyone wants to read it in detail.
