A burst of sound made Castiel look up from his laptop. Seeing a flood of students emerging from one of the campus's larger lecture halls, he closed the computer and stowed his things, zipping up his backpack. He slung it over one shoulder, skirting around the wide flow to wait under an oak tree that stood in a square of dirt amid a plain of cement.

It didn't take long for a Canine to separate themselves from the rush of students, coming over to Castiel. He'd always found it odd, how the stereotype for Omegas were Felines while stereotypical Canines were always portrayed as Alphas. In truth the breeds were roughly split 50/50, and as an Alpha Feline he liked to think he wasn't losing out on much.

"How did it go?" he asked as Dean reached him.

The Omega was two years his junior, though there was hardly half an inch of height difference. Unlike Castiel, who was working on his Bachelors, Dean was almost done with his first two years and still seemed to have a new fascination every month when it came to deciding on a major.

A grimace crossed the Canine's face. "I didn't fall asleep this time. Small victories, Cas."

"That enthralling?"

"There's a reason I put this off," he whined, adjusting the strap of his backpack. "English 102 is way worse than English 101. At least before they had us writing. Now they're making us read shit and overanalyze it."

"You won't have to suffer much longer," Castiel pointed out, only mildly sympathetic as he started walking. Dean had many strengths, this simply wasn't one of them. "One more month."

"One more month," Dean echoed, tone longing.

Castiel smiled indulgently, wondering when Dean would notice he was taking a different route. Behind the building rather than down the main path. Not for the first time he wondered if it had really only been eight months. Since they'd met in August at a party Dean's friends were throwing to kick off the Fall semester, one Castiel had been dragged to by Meg, who insisted he needed to have a nonexistent stick removed from his ass. By the night's end he'd found himself sitting in a McDonald's that had been in walking distance of the party at about two in the morning, arguing with a highly stubborn if very pretty Omega about complete nonsense over Big Macs. Even so, Dean had intrigued him. He'd dated before, if sparingly, had tasted others, but Dean...Dean was special. If anyone asked him Castiel was aware he'd never be able to provide the answer, he just knew. He'd taken his time, courting the Omega as slowly and thoroughly he could manage. Even so it'd still been barely a month before he'd woken up to a foot shoving him off a dorm bed, the Feline ordering him to make coffee. His beloved could be such a needy, demanding little thing. Something he couldn't bring himself to mind in the least.

"They doing construction or something?"

The Alpha dragged himself from his thoughts, turning to regard Dean with a questioning look.

"The parking lot is that way," the Canine reminded him, pointing back the way they usually went. His tone made it obvious he was questioning how many brain cells had woken up today.

"No, they're not doing construction."

"Is there an event or something you don't wanna walk through?"

"No."

"Then why are we going this way?"

The Feline only smiled at him, tail twitching lazily. They were coming up on his target. On the side wall of a building that had been erected for the sole purpose of handling the painfully large freshmen classes was a service entrance. One that was never used, to the point where it had rusted shut and the janitorial staff hadn't gotten around to fixing it. This meant no one would be coming out of it, and few people came down this way. Certainly fewer than the thoroughfare that passed in front of the building. Best of all was the L shaped wall that sheltered the little-used entrance, along with a shallow nitch the door itself was tucked into. Castiel hadn't believed his luck when he'd heard about it through a very subtle grapevine.

There was no one else in the alley between buildings when Castiel slid a hand into the Canine's, drawing him towards the wall. Dean's eyes narrowed and he braced his feet against the motion, his patience at an end. "Cas, what's going on?"

These last eight months had not been wasted. Rather than argue or rebuke or try to physically drag the Canine, Castiel stepped closer and murmured in a low voice, "Do as you're told, Omega."

Dean's breath hitched. His ears laid back, his tail shifting sideways and wagging between his legs, pink blooming in his cheeks. It was a far cry from the reaction Castiel had seen that first night he'd met the Canine, when a similar statement had been growled at him. Dean had gripped the hand that had grabbed his ass and proceeded to beat all traces of dignity out of the half-drunk Alpha. It had been truly impressive, in Castiel's opinion. When Dean had glowered at him and demanded "What the fuck are you looking at?", he'd said as much. It had surprised the Omega enough to earn his attention. In the months since then, Castiel had continued on to earn the honor of voluntary submission. The sort that meant when he said those words, his beloved melted rather than bridled, obeyed rather than lashed out.

Now Dean allowed himself to be drawn behind the wall without further resistance, into the shadowed area around a door half covered in rust. Castiel's free hand came up, cupping the Canine's neck and brushing full lips in a barely-there kiss. "What color are you?" he murmured, thumb stroking his temple.

"Green," was the quiet, almost meek reply.

Satisfied, he tightened the hand on the back of Dean's neck and released his hand. He set his backpack against the door, then slid Dean's from his back and placed it aside. That done, he turned his attention back to his Omega.

"Undo your belt," he commanded, still keeping firm fingers on his neck.

The Omega obeyed, fingers a bit jittery as they undid his buckle.

"Undo your pants. Get them out of my way."

Dean glanced at the brick wall, hesitating, and Castiel tightened his grip briefly.

"Focus," the Feline warned, tone hard. "Do as you're told." He opted not to crack down on him. Not yet. This was new, until now the closest they'd come to doing anything openly was Castiel fucking him into his bed while all his roommates were home, or next to a window with open blinds. He always gave Dean a little extra leash when they were in uncharted waters.

As he watched Dean swallowed tightly, then the tension was leaking from his shoulders, his eyes going distant. This time there was no hesitation, his fingers steady as he undid his jeans. They were pushed down along with his underwear, sliding over his hips and halfway down his thighs, far enough to free his tail.

Castiel didn't need to give orders for what followed. Some things were a part of their status quo unless informed otherwise. The Canine would not move unless directed, would not speak or make a noise unless ordered to do so, would not climax unless granted permission. It had been a wonder to Castiel, now eager he was to please, how quickly he'd been able to obey such strict guidelines. He did have his limits, and the Alpha was careful of them, but for him there had never been a more perfect submissive.

The Alpha sidestepped, putting himself at Dean's side, lightly resting a palm over his throat. His right hand brushing against the bare strip of flesh at the small of his back. He took a moment to stroke the soft, dark gold fur of his tail, making it wag faster. Lips twitching, Castiel turned his attention lower. He was less gentle as he nudged the Canine's feet apart, as much as his clothes would allow, and thrust two fingers between his cheeks.

He was pleased to find his Omega already wet for him, his entrance giving way with ease, a wave of slick rolling over his digits as they thrust their way in. Castiel tilted his head to lightly catch the tip of one flattened ear between his teeth, stroking soft inner walls until he felt slick roll down his wrist. Only then did he had a third finger, stretching him wider, stroking his taint with the pad of his thumb.

Dean didn't utter so much as a whimper, holding perfectly still, taking slow careful breaths. Even when slickened fingers left his entrance to wrap around his cock. The Feline took his time, stroking slowly, letting the Omega's own slick ease the friction, getting his cock to attention before returning to his dripping entrance. He had realized shortly before taking Dean as a lover that, for whatever reason, Alphas had a habit of neglecting their Omega's cock should they have one. He found the very notion ridiculous, and took great pleasure in using every means necessary to make Dean cum hard as soon as he was granted permission to do so. If the Omega could walk a straight line when he was done, he hadn't done his duty as Dean's Alpha.

"Look at you, already so wet," the Feline rasped in one half-flattened ear. "You can hear it, can't you? Needy little whore, you're gushing slick onto my hand. Well, at least there's plenty for me to use your cock too." Giving his rim a tug Castiel mused, "If I wanted to, I could start fucking you already. Look at what you've done."

He held up his right hand in Dean's line of sight, lips curling in a heated smirk to feel the Omega's breath shudder in his chest. Even in the dim light it was obvious something clear and wet coated his hand from fingertips to wrist, a few drops already rolling down his forearm. He'd pressed his fingers together, but when he pulled them apart snail-trails connected the digits. A very tiny, almost inaudible whimper emitted from the Omega's lips at the sight.

Ignoring the sound, Castiel went back to work. As he thrust four fingers inside his Omega he purred, "Such a good little plaything for me. Always so eager. But I'm not in the mood to fuck you today. I want to see my favorite toy cum simply from being touched."

He stroked soft walls, pleased that the Canine didn't even clinch down on his digits. No doubt it was tempting. He caressed and rubbed, searching for his target. It took a moment, but he knew he'd found that bundle of nerves when the Omega's breath hitched, eyes rolling back, his tail jerking before the tip began wagging rapidly. He managed to keep quiet, if barely.

Castiel slowly rubbed taunting circles around his prostate but didn't make contact. He decided not to reposition, liking where he was. From his place at the Omega's side he could see Dean's expression as well as his tail, his right hand able to work freely, his left hand still on Dean's throat, the Canine's arms still limp at his sides.

Before he could continue on, nudging his Omega farther, the Feline beamed when he heard voices coming their way. Two voices, two pairs of feet, walking along and chattering about some assignment or another. Dean stiffened, breath catching, his tail freezing. Castiel's fingers didn't pause inside him, the hand on his neck squeezing briefly.

Lips still a hair's breadth from his ear he stated in a normal volume, "They are of no consequence, Omega. Harken only to me. Let yourself be distracted one more time and I will belt your ass raw. Do you understand? You may speak."

He could feel the Canine's throat work in a gulp under his hand before he answered. "Yes, Alpha. I'm sorry, Alpha."

Castiel grunted, stroking his prostate as the two females outside passed their wall. Dean didn't so much as flinch, something that would take no small amount of willpower at this stage. "Say it again, and this time don't whisper. Lower your voice for any other responses without direction to do so and I will make you scream those words."

Louder Dean repeated, "Yes, Alpha. I'm sorry, Alpha." His tail began a twitching wag once more.

"Much better." So saying, the Feline began massaging the prostate at his fingertips. Aside from a brief stiffening Dean managed to remain motionless and relaxed as well as silent. Part of the initial training had been making him understand that even clinching was movement, and therefore punishable when he'd been ordered into stillness. Anything aside from breathing, and movement of his tail or ears, as his Alpha used his body was grounds for disobedience. The breathing because he had to, the tail and ears because their movement was involuntary.

Castiel moved slowly at first, but began to gradually pick up the pace. Abruptly he removed his fingers to stroke the Omega's erection, fingers pausing to fondle his scrotum and tracing back up his taint to his twitching hole. He repeated this twice more, and while he spent most of his time with fingers buried inside his Omega he did begin to notice a change. As he returned to massaging that bundle of nerves once more he could hear as much as feel Dean's breath coming faster. It was a subtle change, but one he knew meant he was nearing the edge. One he would cling to desperately until either pushed beyond his limits or given permission to tumble over it.

"Mmm, I wonder how close you are?" he mused, his own cock throbbing in his jeans. "Is it easier or more difficult to restrain yourself so close to the open? You may answer."

Dean paused, waiting until a golf cart hummed passed outside to speak so he would be heard. His volume was normal, as ordered, though his voice sounded a bit strained. "More difficult, Alpha."

"Interesting." Lightly licking the shell of one quivering ear he decided, "Maybe next time I'll allow you to use those treacherous vocal cords of yours. Bend you over a desk in an empty classroom and fuck you until you can't help but scream when you're allowed to cum. Would you like that, little whore? You may answer."

"Y-Yes-Yes Alpha," the Canine stammered, breath starting to come in silent pants.

Castiel's ears twitched, picking up on at least one more person coming down the sidewalk so close to their position. Smirking, he sped up his fingers and delicately nibbled on the Omega's ear. "Now be a good Omega for me. You're going to cum all over my hand, and you're going to do it without a peep as some oblivious innocent walks by. You will cum now."

He caught a glimpse of evergreen eyes, pupils blown wide with arousal, roll back as Dean's frame trembled in his hold. While Castiel was vaguely aware of the footsteps, his Omega had his full attention. Muscles convulsed around his fingers, his cock spurting cum onto a thin bed of dry leaves, breath shuddering under the Feline's hand. Even as an orgasm was undoubtedly wracking his frame he remained mostly still and completely silent. His knees didn't buckle, his tail stilling as it trembled with the rest of him. Considering he'd made Dean wail with less when they'd first started, he couldn't help but admire the control, the obedience.

As muscles began to go limp Castiel turned his Omega around, removing his slick-coated hand to press a rough, dominating kiss over his mouth. Dean didn't respond, letting his mouth be used much as his body had been. When the Feline pulled away, now standing face-to-face with his Omega, Castiel nudged the fingers of his right hand against Dean's lips.

"Open your mouth. Clean up your mess. You may use what movement you need to do so."

Still panting, Dean obeyed. He grasped Castiel's forearm and went to work, eyes downcast, cheeks pink for all he worked with gusto. He started with the Feline's fingers, sucking them into his mouth one by one to clean them of slick. He lapped over Castiel's palm, wrist, the back of his hand, even getting the few trails made by drops that had started to roll up his arm at one point. Watching the process was a mistake. Castiel's already aching cock began to throb anew at the sight and sensation.

When he was done Dean dropped his hand, lowering his gaze submissively, his body going motionless again. Even his breathing patterns had returned to normal. Only his treacherous tail gave him away, the very end giving a tiny, hopeful wag.

"Good. On your knees, Omega. Undo my pants."

Dean sank to his knees, padded by fabric bunched just above them. Fingers were quick to obey, for all he himself was still fully exposed. They undid Castiel's belt, his jeans, then returned to their limp position at his sides. The Feline allowed himself a brief, proud smile at this. More than once Dean had earned a spanking for being overeager, going straight for the Alpha's dick rather than simply dealing with his clothes as ordered.

The hand that had been on Dean's neck until now moved to pet his hair. "You may take out my cock." Castiel had to bite back a groan as warm fingers did just that. His voice was more of a growl when he ordered, "Use your mouth and your hands to pleasure me."

It had apparently been the order his Omega had been waiting for. The words were barely out of his mouth before Dean's head dropped, a hand coming up to grip his aching member at its base to steady it. Castiel didn't bother restraining a low groan this time, watching as a tongue circled the head before his cock disappeared through full lips. He let the Canine work at first, the hand in Dean's hair simply resting there, watching through lidded eyes as the Omega's head bobbed, his tongue lapping at his throbbing member.

"Look up," he rumbled. "Let me see your eyes."

Evergreen orbs hazy with lust and a little watery from swallowing his dick lifted to him. Not for the first time the Canine made use of his virtually nonexistent gag reflex to wring a moan from his Alpha. Castiel knew it was a mistake to have Dean look up at him as he gave the Feline head, but he couldn't help it. The sight of his Omega on his knees, jeans and underwear still pushed down his thighs, one hand braced on his hip, the other stroking his cock, swollen lips wrapped around his cock as he gazed upward...gods help him.

Abruptly Castiel let go of the Canine's short hair, bracing his left hand against rough brick as his left hand took its place. This time they dug into Dean's hair, gripping him, dragging him back. Dean gasped, panting raggedly, as he was pulled off the Feline's cock, still staring up at him.

Without bothering to warn him, the Alpha began fucking his mouth. He was already so close, he wanted to use his Omega's mouth as he often did his ass before he was finished. It was one of the rare downsides of having a lover that was both beautiful and talented. Dean didn't offer protest as a hard cock was driven in and out of his mouth, more than once lingering when it was pushed all the way down his throat. His hands had fallen back to his sides when it became clear he wasn't expected to actively service his Alpha, simply be used by him.

Despite knowing no small amount of time had to of passed, it seemed like far too soon when Castiel felt the telltale rise in his groin. He rammed his cock down the Omega's throat one last time, moaning low in his throat as the Canine swallowed around him, then dragged his saliva-coated dick from swollen lips.

"Open your mouth, tongue out," he growled, releasing his hold on Dean's hair.

The Omega coughed, taking a shuddering breath even as he obeyed. He didn't just thrust his tongue out either, anticipating what his Alpha wanted of him. He opened his mouth wide, sticking his tongue out as far as it could go while still offering a semblance of a flat surface. Castiel's newly free hand grasped his own cock, giving it two brisk pumps before climax hit. A sound that was half gasp half groan dragged itself from his throat, his knees buckling, but he held steady all the same. Enough to keep his hand moving, keep the head of his member resting on Dean's tongue, and keep his eyes open. Even as he dragged in ragged breaths his instincts thrilled to see his own cum spurting out, every drop falling into his Omega's waiting mouth. Not for the first time he marveled at how simply watching something could make an orgasm that much more intense.

"That's it, take it all," he rasped, giving his spent cock one last stroke before releasing it. Surprisingly steady fingers reached out, stroking his cheek. "Good boy, not missing a drop. Close your mouth. Swallow. Make sure all of it goes down."

Dean closed his mouth, his throat working his he obeyed. Castiel took the spare seconds to tuck himself back into his pants, fixing his jeans and belt before bending down and crooking a finger under the Canine's chin, his thumb sliding up to move between his lips. He pulled Dean's mouth open again, tilting his head this way and that for inspection. Satisfied his last order had been obeyed, he closed the Omega's mouth and sat cross legged in front of him.

"I'm finished with you. Whoa, careful. Let's get you cleaned up."

He caught Dean's shoulders when the Canine swayed, carefully guiding the Omega into laying down over his lap. Considering all they'd just done Dean still managed to blush as he was positioned ass up over the Alpha's legs. Castiel was reaching around, opening his backpack to pull out a packet of baby wipes when Dean mumbled, "You ain't gonna spank me are ya?"

"Have you done anything to warrant a spanking?"

The Canine folded his arms on the ground, burying his face in his arms rather than answer. Castiel patted his thigh, then began using the wipe to remove all traces of slick still lingering on his skin. Not only would it be an irritation, it could lead to rashes if left to chafe all day. Thankfully Dean had given up grumbling over his coddling some time ago. These days Castiel didn't even have to hold his tail away so it wouldn't tuck in and get in his way.

Castiel took his time, using several wipes to make sure not a square centimeter was missed. He cracked an amused smile when he managed to earn a tiny squeak from the Omega when he included his dick and testicles in his ministrations, an equally tiny whimper when he stroked his recovering entrance. Only when he was satisfied did the Feline wipe his own hand, deposit the last wipe into a plastic bag for later disposal, and fix the Canine's clothes.

Dean got up when he was done, but didn't stand. He rolled over onto his back, backing himself up until he could lean against the brick and close his eyes, still apparently drained. Castiel scooted around, petting his ears gently until he'd earned a small thump from his lover's tail.

"Are you able to walk?"

That earned him a dirty look. "Damn it, Cas, give me a minute would you?"

Castiel pecked his lips gently, then reached over to drag his backpack to his side. As he started rummaging through it Dean groaned softly. "No more surprises. You'll have to carry me back to Baby."

The Feline paused, tail curling back and forth, ears pricking forward. "Mmm, I'll remember that. Next time that will be our goal."

Dean truly must have been drained, because all he offered by way of protest was a grimace as he closed his eyes again and a drawn out, "Fuuuuuuuck."

Castiel smiled, turning back to his search. Once he'd recovered and had been fed Dean would be more receptive to planning future romps. A person had to be patient when their lover possessed the contrasting traits of embarrassed repression and the ability to enjoy a truly creative array of kinks.

The flat box was at the bottom of his bag, placed where no one who went looking could easily root it out. Castiel drew it out, rotating it and holding it before Dean, his heart pounding louder than when he'd brought the Canine to this little hole in the wall. Confusion crossed Dean's face, and before he could ask Castiel removed the lid, holding his breath.

Dean's face went slack in surprise, eyes widening, his breath catching. Even in the faint shadows it was easy enough to see what rested in the long rectangular box. Regardless of what went on in the bedroom, every mated Omega was obligated to wear a collar or some other object to backup the mate mark on their necks. Some only had one, others had a collection, but regardless Alphas often went out of their way to get a collar or collars that were personalized for their Omega. Castiel had every intention of giving Dean more than one, assuming he accepted his first offering.

After a great deal of searching and indecision, Castiel had opted for something simple. He knew very well Dean wouldn't like the ones encrusted with jewels or fashioned of precious metals, not that they were in his budget anyway. The one he'd selected was made of smooth, supple, whisky-brown leather, something that wouldn't chafe or itch easily. A narrow band of sterling silver ran along the middle of the outward facing side, engraved with a pair of outstretched wings reaching partway around to either side. On the inside, 'Property of Castiel Novak' was branded into the leather. The buckle was fashioned of more sterling silver, as was the slender D ring next to it should a leash need to be attached.

"I know it hasn't been a year yet but...you're not just a fuck-buddy even if that's what you originally wanted. You're a companion, a best friend, a partner in crime, a lover. I want you to be my life mate, Dean. I can't bear the thought of being without you. If you want to wait to actually mate, then I'm willing to wait." He clamped his mouth shut to stem the babbling, all his carefully planned speeches already out the window.

Dean was quiet for an agonizingly long thirty seconds before he slowly reached out, picking the collar up out of its box. He turned it over, running a thumb over the leather. Over the name branded into it. Then, to Castiel's muscle-liquefying relief, he brought it up to loop the leather around his own neck. Once it was fastened in place he rotated it, so the wings flanked his throat. A little worried when he didn't notice any tail movement to giveaway his emotional reaction, Castiel glanced down to see Dean was sitting on it.

"You're not going to regret this in a few months, are you?"

Castiel reached out, tipping his chin up until he could catch Dean's gaze, only then noticing his eyes were welling with unshed tears. "My only regret is not doing this sooner. I will not stand around and wait for someone else to steal you away. Now please, get off your tail."

Blushing, Dean obeyed. As soon as it was free the appendage began whipping up and down so fast it was a blur. Beaming broadly, Castiel bent to kiss his newly collared mate.
