Chapter Text
Louis looked at his calendar; Harry had been with him for a few months already, and he was blossoming into a beautiful young omega ready to be mated out. His 18th birthday was approaching, and with that, the omega auction that would establish who got to mate Harry. Alphas would submit applications to be evaluated, and Louis’ opinion as Harry’s carer would be taken into extreme consideration, before giving Harry to his definitive mates. If Harry happened to express a preference, that would be given utmost importance as well, taking into account his welfare.
Harry was really a perfect house omega; he was obedient and enthusiastic, prone to the occasional tantrum but it really just added to his charm, and an insatiable doggy slut in case his future alphas found themselves otherwise preoccupied. He’d taken to Topper immediately, and Louis didn’t have the heart to separate them after the first time, so he’d told Harry that when he felt needy, he could go to both of them, and whoever he found first would take care of him. Harry had been so happy, and since that day, it wasn’t uncommon for Louis to just walk into Harry in perfect presentation position on the floor, Topper jackrabbiting into him. He still looked for Louis quite a lot, seemingly enjoying the cuddles that Louis gave him during their tie, and Louis would knot Harry around four times per day still, but the more time passed and Harry blossomed, the more often he seemed to look for a knot. Every morning, without fail, Louis would find him leaking, his omega hole creampied and loose from Topper knotting him during the night. Or, since he did wake up before Louis, knotting him in the kitchen while Harry was making breakfast. He was such a perfect omega all around, and the time with him had really flown. His future alphas would be really lucky to be mated to him.
He stared at his laptop for a few minutes more, pondering, and he was interrupted by the pitter-patter of Harry’s naked feet on the hardwood floor, running up to his office. He scented the air, not smelling any particular neediness on Harry yet, but sure again, there he was, red-cheeked and grinning, holding up his and Topper’s leash.
“Walk, alpha?” he asked, handing the leashes to him.
It was indeed time for their morning walk, which Harry enjoyed greatly. Louis smiled, indulgently. “Very well, darling boy,” he said. “Bend over, I need to see if you’re clean first.”
Harry obediently bent over Louis’ desk, chest pressed on the wood and hands automatically going to spread his cheeks to expose his hole. Louis had started these inspections since Harry had taken to Topper, because while Louis would clean him in some way after knotting him, Topper at most would eat him out after knotting, which resulted in an extremely drippy omega, both from his cocklet and his hole, and while Louis didn’t mind it, he preferred to start their walks with Harry being clean.
He thrust a finger into Harry’s hole; Harry was wet, but then again, Harry was always wet, his omega body insatiable and needing to be filled. Case in point, the sweet little slut moaned, pushing his ass back into Louis’ finger and trying to get more stimulation.
“Patience, baby,” Louis chastised. When he took out his finger—Harry let out a plaintive little whine that made Louis smile—there were traces of Topper’s cum over it, as Louis had suspected. “Let me wash you, and then we can go for a walk. Inspection done,” he said, with a swat to Harry’s bum.
When Harry got up, he was pouting. “Alright,” he conceded. “Alpha.”
Louis pressed his lips together to avoid showing Harry that he was amused by his defiance. “I will never take away your walks, baby, don’t worry,” he said instead. Harry had taken to calling him alpha instead of Louis, which made his heart grow three sizes every time.
They had a routine in the bathroom, and Louis made quick work of washing Harry up, and soon enough, Harry was squeaky clean, the sweet scent of omega coming out from under Louis and Topper’s ones.
He got the leashes from his office and went to the door, Harry and Topper—the dog had heard the leashes and the steps and had come running—in tow. He put shoes on Harry, then got to the leashes.
“Be calm, let me clip your leash,” he told both of them, and then they were off.
Their walks weren’t long, he mostly got Harry and Topper down to the local park; it was nice to be around nature for a while, and there were other omegas playing around. That way, Harry and Topper could play for a while, and Louis could chat with people.
In the hallway, there was Jackson, Louis’ beta neighbor. “Good day, Louis!” he greeted. “Harry, Topper. Louis, may I?”
Louis smiled. “Go ahead,” he said. “Harry, darling, greet Jackson, please.”
Harry grinned and spread his legs a bit, letting Jackson fondle his cocklet. He tilted his head, baring his neck in greetings in return. “Jackson, hi,” he repeated. He was way less vocal in front of strangers, really only babbling with Louis.
“So cute,” Jackson said. “Thank you. Sometimes I wish I had an omega, but I don’t think I could keep up, honestly.”
“I think that you could get into a pack nest,” Louis said. “Sure, you can’t knot an omega, but they will benefit from semen even without knotting, and I’m sure there’s alphas out there who will appreciate a beta in their pack nest. Think about it, if you really want.”
Jackson nodded. “Thank you Louis, always a pleasure to talk with you.” He gave Harry another fondle in goodbye, and then he got inside his apartment.
Louis tugged a bit on Harry’s and Topper’s leash to make them move and get out of the front door.
It was a beautiful day outside, warm enough that Harry didn’t need any coat and could just walk around nude, and with a light breeze that made Louis breathe in, happy to be out. Harry had a skip in his steps, tiny cocklet flopping up and down with each step he took, and even Topper, amazingly leash trained and with a perfect recall, was tugging a bit on the leash.
Once they got to the park, they went to the designated omega pen and Louis unclipped Harry’s leash, keeping Topper with him. Topper did have great recall, but Louis preferred letting him off the leash only when there wasn’t anyone around, just to make sure. He didn’t think other people would appreciate Topper trying to mount their omegas, and while he was sure Topper wouldn’t, sometimes it was better safe than sorry.
Harry skipped on the soft grass that made up the omega area, greeting his friends by fondling their cocklets and fingering their holes like he’d seen alphas do to omegas, and Louis smiled slightly, then turned around, took a few steps before recognizing Peter on a bench and going towards him.
“Good to see you, Peter,” he greeted. Peter was part of a pack nest as far as he knew, but he’d never met the other alphas, since he was usually the one bringing their omega to the park.
“Ah, Louis,” Peter greeted. “Nice to see you, mate, how is it going?”
“Pretty well, thank you,” Louis replied. “Just taking Harry and Topper out for their daily walk.”
“Me too, Matt’s in the middle of that humpfest you see on that corner, just taking a bit of time to relax, really.”
Louis nodded, looking to where Peter was pointing. Indeed, there was what seemed to be a group of ten omegas or so, all rutting against each other furiously. It was the way omegas played, mostly, the frantic playmating in which they humped each other and they fingered each other and sucked on each others’ cocklets. It didn’t really satisfy them, needing semen or a proper cock to come, but they did need the socialization, and Louis doubted they could actually contain themselves.
Case in point, he could see that Harry had reached his friends, a long-haired brunette and a redhead, and they’d already started humping each other in a cute puppy pile that made Louis smile. If he concentrated, he could hear his high pitched whines.
“Are you keeping up well with Matt?” he asked.
“Much better, honestly,” Peter responded. “We got in contact with the kennel you suggested to me, and went there with Matt for a demo. I shit you not, he creamed his pants as soon as he smelled the dogs, so we’re definitely getting a stud for him, this way we’re going to have a bit more time as well.”
“Very happy to hear,” Louis said. “Matt’s a good omega, and a stud will satisfy his pack bitch instincts, that will calm him down considerably.” Topper put his head on Louis’ thigh, and Louis patted him absently, scratching between his ears.
They stayed a bit seated on the bench, catching up on Peter’s work and Louis’ general life, since his work was, well. Mostly Harry in that moment, idly watching the omegas rolling around their pen in desperate playmating. It was interesting, how playing with each other would only make them more needy and desperate, and yet they couldn’t do any other type of play.
Soon enough, Peter was approached by a desperate-looking Matt, who climbed him and started rubbing himself on his trousers, and Louis averted his gaze politely while Peter took out his cock and got Matt to sink on it to pacify him for a while.
Matt slumped against Peter’s chest, and Peter patted his head fondly. “Omegas, man,” he said. “I’m gonna go to the car so I can knot this one, he always gets sleepy after a knotting and I don’t want to have to carry him to the car.”
“Have a good day,” Louis smiled, making a shooing motion. “Let me know how it goes once you get the stud.”
He looked at the sky, enjoying the light breeze passing through his hair, and still petting Topper idly. Around him, people were bringing their omegas to the pen, or getting them back when they became too desperate to keep playmating anymore, and the air was filled with the delighted shrieks and moans of a bunch of happy omegas.
Omegas lost their mental capacity after presentation, and that did reflect in their language. Harry babbled a lot to Louis, but in very simple sentences that did not convey any deep meaning. That was because after presentation the majority of their brain was now devoted to helping the hypothalamus produce omegin, the hormone who made omegas what they are, and that resulted in an insatiable need to be filled, and the sweet dumbness that characterized them. From there, they tended to be shy about talking in public, and unless you had tour own omega, the sounds they made were mostly giggles, shrieks and whiny moans depending on how they felt.
Topper suddenly raised his head, and sure enough, Harry was running towards him, giggly and sweet and smelling of horny omegas all around. He’d rubbed around with his friends, and now he didn’t smell much like Harry, but Louis could still smell the slick that was dripping from his hole and his cocklet.
“Alpha,” he said breathlessly, then he looked at Topper. “Topper.”
Louis could see Topper’s red rocket out of its sheat, standing proud to attention; he knew where this was going. He smiled. “Go ahead, baby, let Topper scent mark you, you smell like a lot of people right now.”
Harry fell to his knees with a giggle, baring his neck, and Louis lightly pushed Topper towards him, encouraging the dog to scent the omega, nose soon pressing on Harry’s neck. Soon enough, Topper was opening his maw to give Harry broad licks on his face and neck, while Harry giggled and relaxed under topper’s ministrations.
Topper pushed Harry gently on the ground, belly up, and kept going down, making Harry moan and press into him when he reached his little tits, and then laugh when he went to his belly. Louis looked at him cleaning Harry’s cocklet thoroughly, no doubt one of the places that carried the most scent of other omegas. Harry whined and writhed on the grassy ground, unashamed and loud in his pleasure.
Harry knew the routine by now, and he obediently rolled around on his belly when Topper pushed him with his maw, to let his hole cleaned too, automatically presenting for comfort, just like the perfect omega he was.
Louis’ cock was hard in his sweatpants, the sight of Harry presenting for his dog making him chub up. He brought his hand down, rubbing his cock through the fabric. He won’t fuck Harry at the park, because that’s why Topper was there, to take the edge off, but he still enjoyed the view.
Topper, the well-trained dog that he was, as soon as he finished scenting Harry looked towards Louis, waiting for his signal, ignoring the plaintive whine that Harry let out, scent now desperate and overpowering. Louis smiled, licking his lips.
“Topper, mount,” he said.
Topper went crazy.
With practiced movements that could only come from the fact that he would knot Harry multiple times per day, he mounted the omega, red rocket finding Harry’s hole on the second thrust, maw immediately going to Harry’s nape to keep him meek and in submission.
Topper always fucked Harry with the reckless abandon that only a dog could have, jackrabbiting into his hole with short, potent thrusts that always made Harry a whiny, crying mess, whole body overwhelmed with pleasure and multiple orgasms before he got knotted. This time wasn’t different, Topper’s yips and whines mixing with Harry’s moans, and Louis had to give a squeeze to his cock just to find a bit of relief.
There were a couple of people who were watching the mating with interest, he realized, and it made him proud to see that Harry was being fucked so well and looked so good that people were stopping to watch. Topper was a big dog, and while Harry wasn’t that small at almost 18, he made himself small when he was being fucked. Such a perfect omega.
He was tuned to Harry’s wellbeing above everything else, so he noticed immediately when Harry stopped with his loud whines, and he immediately sat up, looking at Harry’s face, trying to understand if something was wrong.
Harry didn’t look like he was in pain, but he’d raised his head, gaze fixed on something, mouth open and drool dripping out of it. When Louis followed the direction of his gaze, he saw another omega on a bench not that far away, being mounted by his alpha, and at the same time seemingly sucking off a black mastiff.
Ah.
Harry observed the scene with rapt interest, bringing his hand to his mouth to suckle around his fingers just like the other omega was sucking around the mastiff’s dick, his own cocklet squirting copiously on the grass, Louis didn’t even know if it was the first or second orgasm. Louis looked again at the scene for a few seconds, then back to where Topper had been shortening his thrusts, sign that he was about to tie. He got up and squatted close to them.
“Such a good doggy bitch you have there, congratulations,” someone called out to Louis, and he smiled, eyes never leaving Harry, ready to help Topper with the tie.
“Thank you,” he said. “He’s a delight to have around, has got one of the sluttiest holes I’ve ever seen.”
Topper finally knotted Harry with one last thrust, resting against the omega’s body for a moment, licking his nape, and then he began the process of turning around, Louis helping along, petting Topper between his ears.
He had a few minutes before Topper tugged himself free, and he finally raised his gaze, finding about ten people looking at the scene interested, the musky smell of alpha arousal heavy in the air.
He smiled, greeting them with a nod.
He received a few more compliments on Harry’s pliancy and his sluttiness, which made him puff out his chest in pride, the fondness he felt for Harry only getting more and more with each passing moment. He helped Topper tug himself free of the tie, and then he examined Harry’s hole with a couple of fingers to check on health and tear. There were none, of course, but it was better being safe than sorry.
He helped Harry get up and clipped his leash to his collar again, petting his tousled hair back into place. Harry looked dazed and fucked out, foggy like he always got after a good knotting. He was dripping Topper’s cum from his hole and the remnants of his squirt from his cocklet, and Louis pressed a lingering kiss on his forehead, scent marking him a bit.
“Let’s go home, babies,” he said.
Back at home, he gave Harry a sponge bath to wash away the residues of the park and Topper a brief wash as well, avoiding a proper bath because he still hadn’t bought a dog hairdryer and he had to go to the groomer to do anything properly. After that, still naked, he set out to make a makeshift nests with pillows and cushions covered by a few blankets, right on the living room carpet, so Topper could cuddle with them.
Harry looked at the nest with moony eyes, and Louis thought back to those applications he had in his laptop for a moment, and then he was diving into the makeshift nest and rolling around, scenting it instinctively, and making Louis and Topper do the same thing. He relaxed when the nest smelled like them, pressing himself up between Louis and Topper.
Louis spooned him for a bit, hands going up and down his sides, while Harry petted Topper and babbled.
“Such a good doggy,” he repeated. “You and alpha make me happy, the happiest omega.”
“You make us happy by being the best omega,” Louis murmured in Harry’s ear. “You’re so good, Harry.”
Harry smiled, pressing a noisy kiss on Topper’s forehead, and then craned his neck to press another noisy kiss to Louis’ chin. “I like it here, alpha,” he whispered. “Don’t wanna go away.”
Louis’ heart grew three sizes. Harry was so sweet and open, a far cry to the timid and closed omega, scared to come to Louis for his needs, that he’d been when he’d arrived a few months before.
“Wanna stay here, baby?” he asked, bringing one hand up to massage Harry’s stomach, and pressing his lips against Harry’s temple.
“Always,” Harry vowed, snuggling into Louis’ arms. “Always so happy with you.”
Louis was taken by the need to kiss Harry all of a sudden. It wasn’t uncommon to kiss your omega, but Louis avoided it with all his cases, not wanting to blur the lines and getting too attached before sending off the omega with their proper mates. He pressed his lips together, his resolve hardening. He’d send his application as soon as midnight struck on Harry’s birthday.
He couldn’t tell Harry, just in case there were complications, so he just kept pressing small kisses to his temple, massaging his stomach slowly. “I’ll keep you as happy as I can, baby. Always.”
Harry sighed contentedly, snuggling further into Louis’ embrace. “So happy,” he babbled. “Happy omega, good omega. So happy with alpha and Topper.”
Louis had become apt at reading Harry’s scent, and he detected the slight change in it, that subtle note of neediness that signaled that Harry needed to be fucked soon.
He brought his hand up on Harry’s chest, teasing his small tits. “Happy like today at the park, when Topper was mounting you, baby? Remember what you saw?”
Harry let out a gasp when Louis pinched his nipple, pushing into the touch shamelessly. “Saw a good omega,” he breathed out, the memory evidently still burned into his brain.
Louis twisted his nipple a bit, nibbling on Harry’s lobe. Harry was such a perfect omega, loud and unabashed at the minimum stimulation. His moans, coupled with his smell, had Louis hard as a rock, and he could see Topper’s red rocket out of his sheat as well, his stud equally as sensitive to an omega’s neediness, but waiting for Louis to give permission before doing anything.
“Such a good omega, right?” Louis repeated. “And what was the good omega doing?”
The heady scent of Harry’s slick was flooding the living room, and Harry kept moaning, high and needy at every exhale. He pressed his chest into Louis’ hand, and his ass against Louis’ dick, trying to get some more stimulation. “Can I be bred, please alpha?” he asked, whiny.
Louis pinched his nipple, hard. “Focus, baby,” he told him kindly. “What was the good omega doing?”
Harry had his hands knotted into Topper’s sides. “Being bred, alpha?” he asked. “Being bred by alpha and Topper.”
“Being bred by their alpha and a dog,” Louis gently corrected. “At the same time. Good job baby, you’re the best omega.”
“Best omega being bred?” Harry asked, and Louis huffed out a laugh.
“Best omega ever,” he answered. “And since you were so interested, Topper and I are gonna breed you like that good omega at the park today.”
Harry moaned, rubbing his hole against Louis’ cock, slicking it up. “Mount me then, please?” he asked.
“Topper’s gonna mount you, baby,” Louis said. “I’m gonna knot your greedy little mouth so you don’t have to suck on your fingers for once. Come on, present.”
And sure, the nest was just a makeshift thing that Louis had made, but Harry looked beautiful, kneeling in the middle of it, chest down and ass up, heady slick scent completely in the open.
If Louis had it his way, the nest would become a permanent one soon enough.
Louis sat up, back against the couch, and positioned Harry’s head between his legs, where Harry promptly started nosing at his hard cock and balls. He took a deep, trembling breath. “Topper, lick,” he commanded.
Topper jumped up, heavy dick bobbing up with the action, and started his routine of licking out Harry’s hole in preparation for the knotting.
“You’re gonna get my cock and Topper’s cock at the same time, babe,” Louis told Harry. “As a prize, because you’re the best omega.”
“Best omega,” Harry repeated in a whine, suckling on the sensitive skin of Louis’ balls.
Louis threaded his hand in Harry’s hair, tugging a bit just to test it. Harry seemed okay with it, preoccupied with suckling and licking Louis’ balls and pushing back into Topper’s maw as he was.
He tugged more, guiding Harry’s head towards the angry tip of his cock. It was big, even by alpha standards, a heavy breeder cock that made Louis able to do his job well. “Take the tip into your mouth, baby, yes, just like this.”
Harry’s mouth was plush and velvety, more delicate than his hole, and Louis almost choked on his spit when Harry experimentally licked at his underside. Harry’s moans were muffled by his full mouth now, but omegas were wired to love the taste of alpha precum, and Harry wasn’t any different, licking and suckling to his heart’s desire.
“Topper, mount,” said Louis.
Topper let out a yip, and then he was mounting Harry with ease. Harry yelped around his cock, and then the thrusts started, each of the short, powerful thrust that the god was driving into Harry making the omega swallow Louis’ cock just a little bit more each time, until Louis was fucking Harry’s throat in earnest with the help of his dog.
Harry looked like a vision. On his elbows and knees, being mounted and fucked by a large husky dog, eyes round and wet, cheeks red, and mouth stretched around Louis’ cock, drool escaping at each movement. Louis could feel the velvety heat, and the continuous vibrations of Harry’s throat when he moaned and whined in pleasure.
He brought his free hand down to fondle one of his nipples, pinching it down almost as if milking him, and Harry screamed around his cock, hand disappearing under his body, presumably to fondle his own cocklet.
Topper was yipping and panting against Harry’s nape, and Harry was moaning and swallowing around Louis’ cock, and Louis threw his head back, hips thrusting up while he pushed Harry’s head down, heat coiling in his belly.
“Such a good omega, fuck, you’re such a good bitch, Harry,” he gritted out. “Made to be fucked, are you? Made to be filled, doesn’t matter if it’s a man or a dog, you just want that knot.”
Harry moaned, Louis wasn’t sure he could understand his words while in such a daze, but Louis’ tone always seemed to make him happy while being fucked.
“You were made for this, fuck, that’s what you need, is it? To be filled in both your holes like a pack bitch. Always so happy when Topper knots you, baby, such a good omega.”
Topper’s thrust shortened, and in turn Louis’ ones became wilder, fucking Harry’s velvety throat in earnest, one hand in Harry’s hair to push his head down on his cock, the other still on Harry’s small tit. “Are you ready to take two knots, baby? Are you ready to take a doggy knot and your alpha’s knot?”
Harry’s face was streaked with tears, and he was sucking greedily on Louis’ cock. Topper popped his knot with one last thrust, and Louis let himself go, knot popping and locking behind Harry’s teeth a few seconds later.
His orgasm was long and almost made him black out, shivers coursing through his body due to the tightness of Harry’s mouth, not made to expand for a knot like his hole was. Harry was swallowing around Louis’ cock, throat working to swallow his cum, but Louis could still see a bit of it escaping from the corner of Harry’s stretched mouth.
He cradled Harry’s head in his hands, keeping Harry’s body in place when Topper turned around, and caressed Harry’s hair and cheeks tenderly.
Harry looked up at him, dazed and adoring, just a sweet little dumb thing that needed to be fucked and taken care of. Louis kept caressing him, and Harry’s eyes slowly closed, the omega seemingly using his cock like a pacifier to fall asleep to.
Louis closed his eyes as well. There were so many things he should be doing. He needed to check Harry’s hole as soon as the tie ended, because he wasn’t there to help Topper tug himself off, and then he needed to send that application as soon as it was Harry’s birthday. And he needed to think whether this would make him fall back on his job.
But, for now, he just enjoyed his beautiful omega, completely fucked dumb, sleeping on his cock.
(Louis did end up sending the application to mate Harry, and it came back with a resounding positive answer as soon as the auction closed. To celebrate, he mounted Harry like a mate would, in the middle of their permanent nest, teeth locked on his nape and telling him that he was his alpha forever.
Harry came four times before Louis could even knot him.)
