Castiel slowed from a run to an easy lope, trotting up to their back porch. They didn't exactly live in the middle of nowhere, but they did live in a house that backed up to an expanse of woods. It helped that most of their neighborhood was populated by those who were either non-human like him or mated to them who were. The house to their left, for example, was home to a vampire and their mate, in the one on their right lived a witch.

Dean was sitting on the brick steps leading up to their wraparound porch, a glass bottle dangling from one hand. He hadn't turned on the floodlights, for which Castiel was grateful. The Alpha slunk up to him, climbing a few of the steps and curling around his mate. Dean absently lifted his arm so Castiel could settle his head in his lap, the fingers of his free hand burying themselves in ink black fur.

It occured to the werewolf as he settled around his Omega, nose immersed in his calming scent, that something was a bit off about it. The change was subtle, enough so he hadn't noticed until he was in wolf form, but it was there. Dean's scent had always been motor oil, lavender soap, and leather wrapped in human Omega musk. Castiel loved that scent, never got tired of it, but now something wasn't quite right about it. He tilted his head, making Dean grunt as his cold nose bumped his neck.

"What're you doing?"

Ignoring the question, Castiel inhaled deeply. Since when did his mate's scent cocktail include cranberries? Dean never ate them unless they were in a pie or in a Thanksgiving dressing, neither of which had happened in months. They weren't even in season right now.

"Jeez, Cas, what's with you?" Dean demanded, pushing his head away. "Settle down."

Castiel huffed, then stilled as something clicked. He had a vague memory from the birds and bees talk he'd gotten years ago, the werewolf version that was far more detailed than a twelve year old might ask for. His father was nothing if not thorough, though he guessed in this case Chuck simply wanted to get it all over with in one go. Among the many facts he'd been hit with that day was one covering how an Omega's scent changed when they were pregnant. All Omega's did, though when you were something besides human it was easier to read as more noticeable, more specific. It differed, though often if they were from the same family the scent would be virtually identical. According to Chuck his mother had smelled like cinnamon, as had Gabriel when he'd been pregnant with his and Sam's daughter.

More important than any of that, though, was a simple sentence Dean's Alpha brother had uttered shortly after they'd found out. The Winchesters might be human, but they spent a lot of time with those who weren't. Castiel vividly remembered Sam's response when he'd announced Gabriel did indeed smell like cinnamon. "Huh. They said Mom smelled like cranberries."

Castiel's nose dropped from Dean's throat to his stomach, sniffing intently. The cranberry scent was even stronger there. His tail began to wag so hard he sent a potted plant flying.

"Hey! What the hell's wrong with you?" Dean demanded.

The Alpha lifted his head, then froze when he saw the bottle still in his mate's free hand. He sent the half full beer flying, earning another protest from the Omega. The scent itself was faint, even if it was unmistakable. Dean wouldn't be far along, a month if that, it wasn't that odd for him to not know. Regardless Castiel had no intentions of letting him drink, no matter how big a fit his mate would undoubtedly have.

"Cas! Damn it, what- did it go to your head this time? I thought you said you'd be calm again."

He had, and he was. Unlike last month they had been home when the Moon Fever had been embraced, and Castiel had just returned from over an hour of running and hunting to blow off steam. After last time he dared not risk being around Dean until his instincts had settled down. It had been a huge relief that he hadn't hurt Dean, even if he did drag his mate to the doctor the following day just to be sure. Considering this recent discovery he was even more glad he'd made sure he was already outside and alone when he changed, not entirely sure how his wolf would have handled the news.

Lifting his head, Castiel gently bumped his nose against Dean's, who swatted at his muzzle. Ignoring it and the muttered, "Knock it off, sappy bastard.", he gently laid a paw over the Omega's stomach. He peered up into Dean's green eyes, whining softly, tail still a blur as it wagged.

"What? You know I don't speak wolf. Just wait until you change back. Now if you'll excuse me, I need to get another beer."

A low growl rumbled in Castiel's throat, his body stiffening. When Dean tried to rise he gripped the human's waist, holding him down. Dean scowled, trying to shove away his paws.

"Damn it, Cas. Since when do you care if I drink?"

Normally he didn't. So long as Dean wasn't actively trying to get drunk on a daily basis Castiel had always opted for the healthy choice of not getting between the human and his liquor. He knew some who did, though barring this newly developed exception he'd never understood why.

The Alpha whined low in his throat, nuzzling Dean's lower belly, peering up at him intently. Come on, Dean was smart. Even in wolf form he could make sense of the less complicated communication attempts.

The human groaned. "Don't tell me I'm sick. You ain't dragging me to the doctor a second time, forget it."

Oh Castiel would definitely be dragging him to the doctor after this, even if he had to carry the Omega to do it. He nuzzled his mate's stomach, then leaned up to lightly lick his cheek. Dean swatted him away again, looking from his mate to his stomach to the discarded beer. Castiel waited, watching as the gears churned. If nothing else, he knew his Omega understood whatever he did had a reason behind it. The Alpha didn't act strange for the heck of it.

When Dean did speak several seconds later, his voice was low, strained. "Cas, am I...do I smell...fuck, what was it? Cranberries?"

Castiel yipped softly, tail wagging even harder, licking his cheek. Dean didn't even try to push him away, a stunned look on his face. Another few minutes passed before he let out a deep breath, muttering, "Fuck. How the hell did this happen?"

The Alpha considered it, nudging his nose under Dean's shirt so he could lick his stomach. Typically male Omegas could only get pregnant while in heat, but there were exceptions, particularly with non-humans. About a month ago was the last Moon Fever. When he'd knotted his mate in his wolf form.

Just thinking about it was a mistake. The Alpha felt heat start to coil in his groin, and he nudged Dean's shirt higher up. The Omega would be annoyed if he destroyed another pair of jeans, so rather than rip through them one clawed finger plucked meaningfully at his waistband.

"Hell no. If you had to be in wolf mode to smell it, then it's new." Dean shoved the wolf's head away, pushing his shirt back down. "And the only way you could have knocked me up was the last time you were like this 'cause I haven't had a heat in four months. You ain't- son of a bitch, put me down!"

Castiel ignored his protests, scooping up his mate and sitting on the grass with him, dumping the human into his lap. Buttons were impossible with claws, but shirts were easier. He shoved off the open flannel shirt, despite Dean's protests, then managed to peel off the Led Zeppelin shirt without ripping it. That in itself was a fete he was proud of, in no small part simply because Dean would skin him for ruining one of his favorite retro shirts.

Shoes were harder, but not impossible, even if their owner was trying to smash your muzzle with their heel. Dean flailed when he was almost dumped on his back as his mate lifted one booted foot, still swearing enthusiastically. By the time Castiel had him down to his pants and little else he was flushed and apparently pissed. If the Alpha hadn't been able to scent his arousal he might have stopped, but he was very horny and Dean was willing. He hadn't expected what it'd do to him, realizing his mate was pregnant.

"Fine, damn it! Just hold on, you ain't ruining these too."

Castiel stroked his mate's back, nuzzling his neck as the Omega hurriedly shucked his jeans and underwear. As soon as they were clear the Alpha dumped him onto his back on thick grass, making sure he was at the right angle before taking a position over him. This way his shadow wouldn't interfere, he had a fully moon illuminated view of his beloved mate.

The word 'beautiful' wasn't one Dean liked, he said it sounded too girly. That didn't stop Castiel from ascribing it to him. Especially now, flushed and aroused and bare on lush grass. The Alpha gazed down at him, slipping one clawed hand under his thigh and gently lifting. Unlike last time he could watch the human's face, could lick the mate mark on his neck and run a rough paw of a hand over his chest. He took his sweet time, ignoring the leg hitched around his waist and the hands gripping his shoulders, trying to drag him down. When he did push inside the Omega, it was when the scent of arousal was thick in the air, when his mate was dripping slick and biting out a demand to "Hurry the fuck up!".

Cobalt eyes never left Dean's face as the wolf slowly pushed inside him, evergreen eyes widening, his breath catching. Fingers dug into his shoulders, holding him rather than trying to push him away as the wolf's cock pressed deep inside him. The Omega's head fell back, a cracking moan in his throat, eyes watering as he was slowly impaled.

Once he was buried inside his mate Castiel paused, lapping and nipping at his exposed throat, giving Dean a moment to adjust. He knew he was a bit much to handle in this state, and while as an Alpha he was very proud of it, as a mate he did worry sometimes. Just because Dean loved whatever was done to him didn't mean he shouldn't worry about harming him.

"Fuck," he gasped breathlessly, head falling back on the grass. "Cas, gods Cas, fucking move would you?"

Castiel obliged. Dean cried out as he went from stationary to brisk, rough movements in mere seconds, fingers gouging into the werewolf's shoulders. Rather than trying to silence him, the Alpha moved even faster, one hand pinning his shoulders to the ground while the other wrapped around his Omega's cock.

"Fuck! Shit, fuck, fuck, fuck Cas, Alpha, mate, damn it- oh gods. Cas, Cas I'm gonna...shit that was way too fast, slow- I said slow down you son of a bitch! You're gonna make me...fuck, fuck, I'm...Cas I'm gonna...

A wordless, moaning cry was squeezed from his throat. Castiel felt pride well in his chest at having made his mate cum so fast. He gave the Omega's cock one last stroke before hot liquid spilled over his paw, shuttering as muscles clamped down around his cock. It was a close thing, but he barely managed to avoid an orgasm of his own. Meaning he had the pleasure of gazing down at his Omega as a climax pulsed through his frame, muscles clinching and convulsing, actually making him buck in the grass.

Gradually, as the tension flowed from his spent mate, Castiel dipped his head down. He ran his rough tongue over sensitive nipples, over his mate mark and clavicle. After a long minute he lifted his free hand, licking cum from his fingers, watching Dean's face, enjoying the sight of a pink blush blooming in his cheeks.

"If you think I'm blowing you right now, think again," he mumbled drowsily.

The werewolf rumbled a chuckle, caressing his cheek with the backs of his claws. No, he would not be doing that. He had something better in mind.

When he was satisfied the orgasm had passed, Castiel began moving again. He kept his pace slower this time, though he made sure to brush up against the Omega's prostate with each stroke, his paw wrapping around his spent cock once more. Dean stirred, a barely audible mewl trickling through his lips. His head even turned, baring his neck in a submissive gesture before he muttered, "Seriously, Cas? Round two?"

Yes, round two. The more turned on Dean had become the more he smelled like cranberries, which had put Castiel's libido through the roof. He didn't want just any climax, not now, and certainly not after Dean could forbid it. Besides, it didn't appear his mate was too upset. He whined a little, trying to pull away, but had stilled after a warning growl from his mate. His arms still remained where they'd fallen before, limp around his head, chest rising and falling rapidly. An honest to gods whimper had even been uttered when the Alpha began stroking his cock again.

Castiel's ears pricked, taking in every sound. The hitching breath and ragged pants of his mate, the tiny keens and moans he tried to bite back, the sound of grass being ripped from the ground by scrabbling fingers, the tantalizingly wet symphony as he slid in and out of his mate's wet hole. He could feel it, that tell-tale tingle at the base of his cock that preceded a knot. If he came now it would swell, he could knot his beloved mate once more. Perfect. He wanted to do it again, to watch Dean's face as they were bound together, as he was filled to his limit.

Full lips parted, giving voice to soft gasped before Dean moaned, "Cas, please...Alpha, mate, don't stop, don't...I will fucking kill you if you stop...fuck, Cas, fuck...fuck me, fuck me, please...

Until that moment Castiel had been very proud of his control considering he was running on almost pure instinct at this point. Dean's words effectively shattered that control. The slower pace was tossed aside in favor of mindless fucking, making his mate yelp at the abrupt change. His face contorted, back arching, a wordless cry piercing the night air.

The werewolf snarled, claws piercing flesh where he gripped Dean's hip with one hand, the other braced to keep the human's shoulders from moving. He dipped his head down, running his tongue over sensitive nubs and lightly nibbling them until his mate keened. He didn't bother stroking his cock this time, Dean looked as though he'd go over the edge without it. For someone who liked his independence and freedom, all it took was a good set of bonds to make the Omega wet for his mate. Castiel had taken great pleasure in getting creative in that department when they were both on two legs, rendering his Omega immobile in various positions before taking him.

For now, being held down by the werewolf was enough. For the second time that night Dean went over the edge, a helpless cry of ecstasy accompanying it. He convulsed on the grass, claws breaking skin as the Alpha held him steady, his won climax crashing through him. Limbs shuttering, a quiet howl in his throat, Castiel never tore his eyed away from his mate's face. Dean's features contorted, eyes rolling back, a shutter wracking his frame under the Alpha's hands. Cum painted his still flat stomach, muscles clamping down over the werewolf's cock. His mouth fell open a little, full lips parting as the Alpha came inside him, a quiet gasping whimper on his tongue as cum filled him, Castiel's knot swelling.

It was easily one of the most beautiful things Castiel had ever seen. Right up there with waking the first morning of their honeymoon and gazing down at his new mate, the mate mark still fresh on his flesh and morning sunlight gracing a face serene with sleep. Even knowing it was creepy hadn't dissuaded the Alpha from spending several minutes watching his mate during those precious occasions when he woke in the mornings to find Dean still asleep. The only times he was allowed the pleasure of admiring his self-deprecating human mate was when he wasn't conscious to complain or shove him away. It was also when he could work on his private goal of trying to count his freckles.

Right now he was too busy taking in the overall view and trying not to collapse on top of Dean as he fell limp, chest rising and falling rapidly as he caught his breath, face slack in bliss. He was so drained even the automatic, instinctive reaction to dislodge himself from his mate's knot before it locked them in place hadn't showed itself. Even an experimental tug of the werewolf to make sure the knot had done its work had only earned a soft whine from his spent mate.

Castiel tilted his head, reaching out a hand to stroke the Omega's cheek. One thumb brushed his lip, evergreen eyes fluttering as his mate caught his breath. He was struck by the sudden urge to kiss him, which was an impossibility in this state. He settled for petting the human, stroking him, caressing him, and just enjoying the view.

It took a while for his knot to deflate, and before that Dean began to stir. Castiel had already taken the liberty of cleaning his mate's cum again, and was alternating his marveling gaze between the Omega and his stomach. They had discussed it, of course, but Dean had wanted to hold off a little longer. Naturally it seemed Mother Nature had decided to have her say in the matter. Once he got over the shock Castiel knew Dean would be as happy as he was.

"I need to build you a doghouse," the Omega mumbled, obviously trying not to move his lower half. "Your ass so belongs in the doghouse right now."

Castiel simply hummed, gently licking his jugular, unfazed. Dean had been making that threat since they were dating, he doubt he'd follow through now. He'd only worry if his mate brought home lumber.
