He pushed his brother playfully on the arm with a smirk before he headed back with a disgruntled Sam in tow. “I guess you lost it? again”, Sam muttered. 

They had been after this thing for weeks and their dad seemed more and more obsessed each passing day. Dean’s ability to see in the dark was a godsend; otherwise they wouldn’t have stood a chance. “Keep your teenage hormonal grumpiness to a minimum, would ya? And yes, I lost it but not before I saw where it was going”

He turned around quickly to catch a branch that had almost slapped Sam right in his face. “And I know you can’t see much out here right now but could you at least try to watch where you’re going?”

The look Sam gave him seemed to soften him up a bit. He sighed with fond exasperation and they walked the last bit side by side, Dean’s tail wrapped around Sam to gently steer him. “What do you mean you lost him?!”, John barked at Dean. Sam just stood beside them watching. Dean cowered slightly with his ears slicked back against his sandy hair, his tail tucked between his legs, the tip anxiously twitching. None of this could be read on his face though which was an impeccable mask. Sam knew Dean had tried to get his catboy mannerisms under control for as long as he could remember, but it continued to be the one thing he couldn’t get a handle on. “I’m sorry, sir. But he was heading north in a straight line. If we leave now we might be able to ca-”

“We?”, John huffed “No, you two have done enough. Stay here with Sam..”, he started cramming things into an old bag “.. I’ll keep in touch. And in the meantime you two stay put, you hear me?”, he turned around glaring at Dean with a raised finger. 

Dean straightened his back with what looked like sheer force of will and nodded solemnly “Yes, sir”

Before they both knew it, their dad had slammed the door shut and the soft rumble of the Impala could barely be heard anymore over the downpour outside. “I wish you would stand up to him”

“Sammy, don’t start”

“No, I mean it, Dee.”, Sam insisted, still upset with their dad’s behaviour. He followed his older brother to the couch and sat down beside him when Dean picked up the remote.

“You did everything you could. Hell, if it weren’t for your sight we couldn’t have tracked him at all and it’s still not good enough for dad”

Sam took in the sight of his brother, jaw set and eyes pointedly fixed on the TV and tail whipping dangerously beside him. “Dea-”

“I am not having this discussion again. He trained me to be better than this. He trained me even though everyone told him he shouldn’t. He took a chance on me and I failed. End of story.”

Sam just looked at him completely baffled. “Why wouldn’t he?”

“Drop it, Sammy”, he bit out. Sam started to get increasingly annoyed with his brother.

“Is this the kit thing or the omega thing? because Mom was both, you’re only three quarters, and Dad had no qualms about her ability or worth”

Dean threw the remote across the room making it split into pieces against the wall before getting up and leaving the room. “The only one thinking less of you because of it is you, Dean!”, Sam shouted after him but Dean had already closed the door.

For once their dad had gotten a great deal on renting this little house at the outskirts of town and for the first time since they both could remember they had separate rooms: the nights when John was home he usually slept or passed out on the couch in front of the TV.

Sam exhaled an angry huff, grunting as he did so and clenching his fists, slamming his own bedroom door shut and throwing himself on the bed.

He woke up in a pool of his own sweat, his body writhing back and forth and no matter how he positioned himself his body just couldn’t find a comfortable spot. His breathing was ragged and he had trouble finding his bearings, panting and clawing at his covers to get them off. He hissed suddenly as the overly starched fabric dragging over his crotch made him acutely aware of his painfully hard, leaking erection. He mumbled something not even he himself could decipher and rolled over onto his stomach, groaning at the pressure and friction against his dick. He checked the time on his phone. 3 AM. What the hell was going on? 

He felt feverish but without the accompanying fogginess clouding his thoughts. His skin felt cool to the touch but from the inside he felt like he was burning and it all seemed to originate from his lower abdomen and crotch area, like water ripples radiating out through his body. All his thoughts were focused on his cock- he’d never been so hard and throbbing in his life. He whimpered in relief and pain as he closed his fist around his shaft and gave an experimental tug. Instantaneously he felt a small relief urging him to keep going, jacking himself, tugging and squeezing with needy and pained little whines spilling from his lips, desperate to find release. 

His back arched a bit as he started feeling the familiar jolts and warmth coil deep within. He whined and whimpered, desperate for it to be over. He just knew, he just knew knew knew that if he could just come all of this would be over and he would feel better again. He quickened his pace, feeling his abdomen tighten and his balls draw up. He came with one hand in a firm grip fisting his cock and the other clamped over his mouth to muffle the sounds erupting from his lips. The fire lifted a bit then, but not completely; but it was enough for Sam to relax back against his pillow and enjoy being able to breathe normally again. The relief didn’t last long. He could feel himself harden again in his grip and what was worse was he could feel the distinct tightness of the base of his cock swelling slightly. “DEAN!”

Sam hung against the door post, barely holding himself up, gray worn sweatpants hanging loosely on his hips. He didn’t even have the energy to cover his obvious erection tenting the fabric.

Dean came stumbling, or what could be considered stumbling by Dean’s standards, into the living room, rubbing the sleep from his eyes. “Sam, what the he-”

He stopped dead in his tracks, warily scenting the air. His eyes turned the size of saucers and he swallowed thickly. “..an alpha?”, he breathed, looking completely dumbstruck “..you presented as an alpha, Sammy?”

Sam just panted heavily, his eyelids drooping. “Dean, I can’t-”

And once again Sam was deeply grateful for Dean’s feline reflexes because if not for them he would’ve broken his face against the wooden floor. Dean held him up against the wall. “Jeez, Sammy you look like shit”

Sam smiled weakly “Ain't so hot yourself”

Dean just huffed and brought his tail up to swipe the layer of sweat beading at Sam’s forehead. “C’mon, let’s get you to bed”

Dean snaked an arm underneath Sam’s pits and tried to lift as best as he could with Sam being at least a head taller. The close proximity felt soothing and Sam unconsciously slumped against his big brother’s frame. Dean suddenly stiffened. The air felt thick and Sam thought he could sense something in his haze. His nostrils flared as he inhaled the most delicious aroma he’d ever smelled. It was a scent of earth, moss, rain and honey- it made his mouth water. “What is that?”, he breathed, greedily inhaling more of the sweetness wafting through the air.

Dean cleared his throat awkwardly and rather ungently let Sam down on the bed. “It’s me”, he said stiffly, his ears leaning back a bit. “It’s my catboy and omega biology reacting to alpha in rut pheromones. I have no control over it”

Even in the dark Sam could see Dean blushing something fiercely. Sam’s brain crashed momentarily. Dean was slick? Because of him?

Dean cleared his throat once again, refusing to meet Sam’s gaze. “I’ll head out to the 24/7 pharmacy and get you some.. stuff. I’ll be right back”

And with that he left, his tail hanging low between his legs with a barely noticeable twitch.

Sam fell into a restless sleep, tossing and turning, tangling the sheets with his long limbs. When Dean finally got back Sam was a tangled, sweat slick mess and because of it, the air was thick with his alpha scent. Sam woke up from his brother crouching beside his bed and tapping him on the forehead, his face assembled in a neutral stiff mask. “Wake up, Sammy”

He looked rigid and cautious, the endearment the only sign of any kind of emotion. “This is what the clerk girl told me was basic first time rut stuff so..”, again he did the throat clearing thing, looking away “.. yeah, go nuts”

Dean patted him awkwardly on the back before getting up and walking out into the living room, closing the door behind him.

Sam tilted his face upwards, scenting the air and letting out a small shiver when he smelled the sweetness of omega pheromones and omega slick in the air, not giving a second thought to that the source of it was his own brother..

Wanting Dean was nothing new to him; he’d wanted Dean in any which way since as long as he could remember and when he hit puberty and a new kind of want joined the party nothing really changed. Dean was and had always been the center of Sam’s affection. But this, wanting this way, knowing that they were in fact a perfect fit, sharing in a flawless contrast, alpha and omega, human and kit, being the black to the other’s white- this was a whole new kind of want. And Sam knew Dean saw him as a little brother and nothing more, but just knowing that even though Dean didn’t want him, his body very obviously did and that knowledge did things to Sam’s brain, making it shortcircuit and completely fritz out.

He clung to the scent in the air, shamelessly stroking himself to it, imagining what it would be like having that slick on him, around him or even tasting it. He threw his head back against the pillows, his body slowly returning to it’s state of burning him from the inside.

He reached down with one hand on the side of the bed, blindly searching for the bag Dean had left there. He brought it up, rummaging through it until he found a bottle of lube and an extremely weird looking toy that he understood, after a quick glance at the box, was a replica of some omega pornstar’s ass with an inflatable ring around the entrance to simulate an omega clenching around the knot.

“Typical”, he snorted. 

The snort turned into a moan halfway as he felt another jolt shoot through his body. He made quick work of the bottle cap, squeezing a generous amount into the toy and on himself before letting the silicone sink down over his swollen, aching cock. He groaned loudly, not a thought in his mind on being quiet or that he wasn’t alone in the house. The slick channel of the toy had bumps and ridges designed for extra stimulus and it was the most mindblowing thing Sam had felt in all his 18 year old life. The squelching noises the toy made each time he thrusted should’ve been grossing him out but instead it only added to the euphoria. The sounds just kept his mind on the wetness of the lubricant, how slick it was against his shaft, slick; the image of Dean took form in his mind, splayed out on a bed naked and begging with something wet and shiny running down his thighs.

Sam came with a muffled groan, his abs constricting as he arched up, shaking into the toy. He forced his eyes open and they caught by the little rubber ball hanging by the toy’s opening. He reached out a tentative hand and squeezed.

He shifted in his seat, the involuntary slick making his ass uncomfortably wet and his raging hard on, that refused to go down, was not really elevating his comfort levels either. He tried to convince himself that this was all just biology and that he did not in fact lust after his newly turned alpha baby brother. It was admittedly hard to convince himself of this when that little annoying voice in the back of his head kept reminding him that he’d had ridiculously inappropriate thoughts about Sam for years. He growled, squeezing his eyes shut and grinding his teeth together trying to push the thoughts far, far away.

He zapped through the channels, looking for the least sexual program he could find. He settled on an infomercial led by an obese older woman and a guy that looked more or less ancient and ready for death. “Perfect”, he breathed out in a huff and slumped back in the corner of the couch with his sandy coloured tail wrapped around him, the tip slightly twitching.

A particularly loud moan reached Dean’s sensitive ears causing him to jerk and his head to snap up toward the sound. He closed his eyes and clenched the muscles in his ass and thighs to alleviate some of the tension and he had to bite down a whimper. He could not, would not take advantage of  his hormonal baby brother; I repeat: He would not, could no-

But there it was; the thought of Sammy creeping into his thoughts. His long tan limbs and lean muscled body stretched out in his bed, a toy working around his knot in slow precise strokes. Dean shuddered and shook his head. He would go crazy if he kept this up. The pheromones clogging the air made it impossible for him to think, but what really crept under his skin and made him see red were the revolting smell of fabricated omega. It was part of the First rut-kit he had picked up for Sam. 

The girl at the pharmacy had said that it was really helpful in calming the alpha down. Still it smelled like Sam had drenched himself in it and it did nothing to slow him down from what Dean could hear. Shame coloured his cheeks when a possessive growl rumbled quietly in his chest as a fresh wave of fake omega came wafting through the door. This had to stop.

He quickly got up and headed for the door; he left the TV on, hoping it’s volume would shield him from Sam’s desperate grunts and moans. He slumped down on the porch step under the flickering lights, idly scratching at the peeling paint. He couldn’t smell the pheromone spray anymore but he could still smell Sam, warm and inviting like salt, earth and something that was just Sam; thankfully the fresh air diluted it to the point where the incessant throbbing in his private parts subsided and he could think somewhat clearly again . 

What struck Dean most about the whole situation (besides him wanting something that so clearly was wrong wrong wrong) was Sam’s lack of aggression; usually Alphas were remarkably aggressive during their ruts and especially their first. But Sam only seemed strung out and horny beyond all logic. At first he’d thought it was him calming Sam. That the scent of an omega close by had a calming effect on him but that didn’t really make sense either as that should’ve made it worse; that should’ve made Sam crazy and trying to claim him. Dean let out an involuntary shiver at the thought. He shook his head and hauled out the pack of smokes he’d hid from his dad and brother from underneath the porch. He lit up, sighing in relief when the smoke hit his lungs and cloaked the last trace of alpha in the air.

He put out his cigarette against the gravel and threw it in a lidded glass jar he kept with the pack and put them both away deep under the porch. He got up, slapping the dust away from his jeans when his ears perked up- he could hear nothing besides the TV. A sigh of relief left his lips and he felt his whole body relax. That could only mean one thing.

Dean toed his boots off outside and closed the door gently behind him as he got in, careful of making any noise that could wake his brother up.

He switched off the TV, relieved at the silence, and leaned downward on all fours to stretch out his back and crick his neck. He was aware of how very feline his behaviour was and that was why it was something he only allowed himself when he was completely alone. He groaned happily once the final pop of his back sounded, and got up. Locking the door and switching off the lamps he scented the air, making sure everything seemed as it should. The scent of fake omega was almost gone to Dean’s great relief and the scent of desperate horny alpha was replaced with happy horny alpha.

Dean felt himself twitch in his jeans but still snorted, shaking his head. “Finally satisfied, ey Sammy?”,he chuckled quietly as he made his way to his room. 

The closer he got the stronger the scent of alpha got which didn’t make any sense since Sam’s room was on the opposite side of the living room. His ears stood straight up on his head as he came to a stop, his tail swishing warily behind him. He could hear rustling inside his room, the sound of sheets against sheets and-

He slowly creaked the door open, and if he wasn’t soaked through his boxer briefs before- the sight he was met with surely did it. Sam laid completely naked on his bed, grunting and furiously rutting against the mattress, gripping Dean’s pillow possessively and inhaling deeply from it, a content growl purring up his throat.

Dean swallowed thickly.
