Chapter Text

Heero and Duo were not known for being masters of long-term plans, nor was it ever required of them before. First, their childhoods - challenging and agonising. Then the war, much the same. Finding themselves after the war, which had taken years, jobs, and learning to navigate the world not only as former soldiers, but as freshly presented alphas. Then, finding each other again, after all that dust had settled. 

Now, they had newer, different problems - ones that involved their future. Ones that would, hopefully, involve a certain favoured omega.

Heero and Duo wanted a family, and they needed help to make it. 

Duo and Heero let themselves into Relena’s house quietly, the pair of alphas not rousing any suspicions. Sporting their Preventer jackets, they were recognized for their frequent visits and assignments providing security to the now Foreign Minister. 

It was known that said Foreign Minister - an omega, and a highly desired one - had yet to choose any long-term partners. Her rejections of some of the Sphere’s more famous alphas had become legendary over the years, but it didn’t stop them from attempting to court her. 

Less known, of course, was that two alphas among her security team would pass their ruts in her bed - so little known in fact, that Heero and Duo had only discovered the truth about in the past year.

Preventer policy dictated that alphas in their ranks were barred from using suppressants. This kept the full wheelhouse of their heightened strength and senses at their disposal at all times, but at the cost of those alphas going off-duty every few months due to rut. For many of them, an omega or beta partner at home would satisfy their primal needs, or they would use a service or tough it out alone, returning to their regular duties a few days later.

Between two paired alphas, though, rut presented a trial. Heero and Duo attempted passing their time together once, and only once, after they had chosen each other as mates. The sheer embarrassment of needing Sally to patch them up after had lead them to quickly agree that whatever they were doing prior to pass their ruts before, was how they should continue now that they were otherwise exclusive.

They had both been stunned when Duo returned home exhausted and spent after a summer rut, and climbed into the bed he now shared with Heero still carrying Relena’s scent. Heero hadn’t been able to hide the fact that he’d recognized the omega’s pheromones immediately, obsessed with the scent and taste of his - their - preferred omega lingering on his lover’s skin. 

The result had been some of the best sex they’d ever had, but it did present a potential problem - both alphas were clearly enamoured with their omega paramour and had no intention of giving her up, even if the only piece of her they had was during their few days of inconsolable need every few months. They'd waited expectantly for jealousy or, worse, the possessive rage of an alpha to rear its head in them at the thought of sharing Relena, but it never came. 

With that last lingering unknown finally spoken between them, Heero and Duo had been happier than ever together, quietly carrying the shared knowledge that they had a safe haven in each other always, and in their chosen and willing omega - if only for that few days at a time.

Though happy, the further the pair settled into their routine and relationship, the stronger and more demanding their cycles became. Both alphas knew the risks of repeatedly seeking out the same omega to sate their ruts, but they were not long-term planners. They’d had no scheme to manage those instincts, including the deep and instinctually possessive need to touch and scent and breed Relena that came over them during ruts and took longer and longer to subside each time they indulged it. 

So, for one of the first times, they devised a real plan, together - one they were at Relena’s home to discuss. 

Heero took a seat at the table in Relena’s kitchen, shifting and looking around over each shoulder before he settled and relaxed back into the chair. Duo closed a hand over Heero’s shoulder as he stepped around and sat in the next seat, dragging it even closer so he could shift to holding his partner’s hand. 

Duo thought he had a good handle on his nerves until he watched Heero shift in his seat, his blue eyes scanning the room carefully before he let out a held breath. Duo could count the number of times he’d seen Heero truly nervous on one hand, and those had all been different - under threat of death, mostly, or with high risk targets so deadly any mistake could cost life and limb of not only them, but their team. 

As intimidating as Relena could be, she knew them, and cared for them. She was also an omega, and one who knew their scents; she’d smell their anxiety a mile away if they couldn’t contain it. 

“The worst thing that happens is that she says ‘no’, right?” Duo felt Heero squeeze his hand lightly in reply, still looking off toward the main kitchen door. 

Relena walked in at that moment, smiling the quiet, contained way she always did when she saw them. That quiet smile fell as she sat down at the table; their anxiety hadn’t passed her detection. “Have you been waiting very long?”

“No,” both alphas spoke at the same time, both trying to sound breezy and failing miserably.

“Right.” Relena brushed her hair behind her ear, glancing away from the table before she looked back at met Heero’s eyes, then Duo’s. “I think I know why you're here.”

Duo looked at Heero who shrugged lightly, turning back to the omega. A rare brush of her own anxious, fretting pheromones lingered in the air, matching the way she tucked her hair behind her ear again before hiding her hands under the table and threading her fingers together. 

“I just want to say that I’m sorry,” she continued, staring at the base of her water glass. “I know you’ve been depending on me.” As Relena pressed her lips together, her scent shifted further; Heero and Duo sat up, feeling the displeasure passing through her. 

“Relena, we -” 

“I don’t think I need you to say anything,” Relena said, and Heero closed his mouth quickly, his expression as furtive as Duo’s. “I've tried my best,” she said, but trailed off again, shifting her focus away from the table, blinking back tears. “I didn't mean for it to happen. I'm sorry.”

“We don't-”

“You don’t have to say anything,” Relena said again sharply, swallowing hard before her expression flattened again. “I understand that this is going to be… hard. I have been working to find replacements that you'll be able to trust and depend on, for the next time you're in your ruts.” 

“Relena, what are you talking about?” Duo asked, interrupting her before Heero could. “Did you think we were coming here to fire you?”

It was rare for them to see Relena off balance, and she looked more confused than they were while she stared at them, considering. 

“... I think you should tell me why you wanted to talk, then," she finally murmured.

“We want to have a baby with you,” Heero said in his usual way, clearly and utterly divorced from pretense. If the stakes were any lower, Duo would have laughed out loud over it, but each of their anxious scents still milled in the air, stifling him.

Relena was speechless. 

Duo brushed his hand over Heero’s, willing his partner to let him take over. “You’ve been with us in our ruts for a while now,” Duo said carefully, breathing through his nose and bracing as he sensed Relena’s anxiety climbing. “We know it’s a lot to ask, it’s not something we would ever bring up lightly. You haven’t claimed anyone, it doesn’t seem like you plan on it, and we thought-” 

Heero stiffened next to him, feeling the rush of pheromones from Relena at the same time Duo did. He scrambled to pick up where he had left off. “I just mean-”

“I understand.” Relena’s voice was low. She had turned her attention away from them again, reaching for her water glass and swirling it, watching the water. “It’s only natural that you would want that.”

“... Right,” Duo said carefully, feeling that it was the wrong answer, but unsure why.  

She stared at her water a little longer before taking a sip and swallowing, clearing her throat. The little exercise reset her somehow, her scent quickly dissipating as she put the glass back down and looked at them again. “I'll have to think about it,” she said.

“Of course.” Duo glanced at Heero again before continuing. “I mean, we know that we’re compatible, at least, but it’s a lot to ask. We don’t want you to think-”

“I understand why you’re asking,” Relena reiterated, and Heero shifted again in his seat. 

“What were you saying,” he said quietly, “about replacements?” 

They didn’t miss the way Relena’s expression tightened. “I-”

“We don’t want replacements,” Heero said. “Why would you think-"

“Heero,” Duo put hand over his partner’s arm, trying to reassure him despite feeling wildly unsure of himself. “She wasn’t-”

“I was contingency planning,” Relena said. “You must have considered what you’d do if I wasn’t available anymore.” 

Heero shook his head slightly, still fixated. “No.” Once again, Duo held back a laugh, relieved to see Relena giving a small, familiar smile. 

“But we have really thought about this,” Duo said, trying to steer the conversation back to their goal. “We know what we want, and we know we will be great dads.” Duo basked in the soft expression Heero gave him before they turned back to Relena. 

“Right. I’m honoured that you would ask, and I'll need time to fully consider it.” She stood, smiling at them in a way that didn't reach her eyes. “There's some other matters I need to attend to. Please forgive me if I don't see you out.”

“We know the way,” Heero said, and she left without any further ceremony. 

The pair of alphas let themselves out and walked silently back to their car, climbing into their seats and processing.

“Was that… good?” Heero finally asked, and this time Duo let himself laugh quietly. 

“It wasn’t ‘no’,” he said reassuringly, turning on the car and putting it into gear. 

Heero sighed and put on his seatbelt. “She doesn’t think we’re serious.”

Duo smiled at him, leaning in to press a peck to his partner’s cheek. “So we’ll show her.” 

Chapter Text

Relena had witnessed Heero and Duo’s determination in the face of adversity many times. Having been lucky enough to know them and learn about their lives, she knew that tenacity had been pulled out of them both by pasts so devastating it made her heart ache. During the war and now for missions with Preventer, their wills could carry them across the Earth and Space. It was the single most attractive thing she had ever seen.

Relena had known better than to expect the alphas to give up on their proposition - a baby, her baby, their baby - and had dedicated time to getting her response in order. She had already slipped enough, but that time was over. Relena had iron determination, too, and she could wield it.

Of course, Duo and Heero knew that all too well.

Duo thought in circles as he walked in them, pacing the kitchen of the home he shared with Heero. They hadn’t heard from Relena in days, which seemed completely reasonable - she’d flown off-planet the day after they’d met up, taking an alternative security crew with her. Both alphas had underestimated how quickly the possession would set in now that they had made their overture, and both were feeling very unreasonable about her being so far away.

“She has to say yes,” Duo muttered, finally stopping and standing next to his mate.

Heero made a low, quiet noise, one Duo recognised as ‘I hear you, I see you, and I won’t be talking about it’. Duo sighed, rubbing the back of his head. Even after his quiet acknowledgement, Heero hadn’t moved from where he stared at their coffee maker as it percolated. Their house was totally silent but for traffic quietly passing outside, and the drip of the coffee as it brewed into the pot.

Duo meandered over and nudged his shoulder against Heero’s - the other alpha didn’t shift away, nor did he lean in. Duo leaned against Heero instead, nestling his lips against Heero’s neck, breathing in his scent.

Heero turned his head and sighed, twining his fingers into Duo’s and pulling his mate’s arm around his flat abdomen.

“We’ll get her, Heero,” Duo said. “We just have to convince her.”

Chasing one of the most coveted omegas on Earth was never going to be easy, but challenge had never deterred them. The two alphas held each other until Heero pulled away, reaching up into the cupboard to take down two clean mugs and pouring the fresh coffee into each of them.

“We can’t convince her,” he finally said quietly, handing Duo the other mug. “She’s got to think it’s her idea.”

Duo smiled, his anxiety giving way. Even if Relena was known as an immaculate negotiator, these two alphas knew her better than anyone.

“We’ve got this.”

—------------------------------------------------------------------------------------------------------------------------

It only took a few days back on Earth - and back amongst her usual staff and security personnel - before Relena felt as though she would trip over the alphas at every corner, whether at home or at work. While it started innocently at first, it soon became clear the alphas were taking, if not orchestrating, every opportunity possible to touch her. A hand on the small of her back ushering her from a room; fingers wrapping around hers as they offered her a hand to get out of her car; leaning in to murmur directions and cautions in her ear so close she could feel their breath on her neck.

Then, the gifts started appearing. Relena knew that being courted by two alphas raised by, well, wolves, would result in some interesting instincts, but they had surpassed her fantasies by a long shot.

Duo had always left her things - mementos, trinkets, forget-me-nots - anywhere he thought he could get away with it. The baubles and tokens left on the pillow next to her as she slept, or slipped into her pocket unawares. The heirloom ring she found inside her locked desk drawer, stolen from a woman who’d offended her in passing.

Pretty things, he would say, for a pretty girl. It had been a sweet and unexpected surprise, before, but now every time Relena turned around, she would find some new little reminder of Duo’s presence in her life.

When Duo took a week off the continent to work on a mission, the tokens of affection didn’t slow. Heero would linger in the corner of her vision throughout her meetings, loitering in the wings as she addressed crowds, giving the faintest blink-and-you’d-miss-it smiles after she would glance down at a podium and find his notes. Written in his perfect cursive, she’d found them occasionally before, pointing out new data she should discuss, ways to adjust her speeches to perfect them, and occasionally quiet affirmations that warmed her from head to toe.

Once, Relena barely caught herself before laughing into the microphone, glancing down to find two perfectly written lines of the most inane gossip she had seen regarding the nemesis of her most recent proposed bill. Any intimidation she'd felt about her adversary had completely disappeared, and she'd delivered a speech so motivating it had been credited with pushing the bill to pass. Heero had smiled at her in earnest when she mentioned it later, and she and Duo had basked his happiness the entire drive back to her home that night.

It was impossible to combat all the tiny, perfect affections. No matter how much she resolved that the alphas would lose interest in time, Relena found she hoped they wouldn’t. She caught herself smiling at the smell of fresh flowers in her office or at home, always replaced by Heero before they even began to wilt. Relena could hardly remember why she had wanted to deny them what they wanted - a family, their family - in the first place. They would watch her so earnestly, so hopefully, that the thought of turning away their gestures made her throat go try and her chest so tight she could barely breathe.

By the end of that month, Relena could think of nothing else but these two alphas - where they might be, when she might see them again, and how easy it would be to give in.

Her brow creased with consternation as she entered the bedroom of her hotel suite one night, hearing Heero and Duo talking quietly to each other in the hall. She hadn’t bothered closing the door behind her, knowing the pair would sweep her space one last time before she settled to sleep. Being away from home was commonplace for her, but stressful to her omega instincts; having the two alphas with her was soothing to her, perhaps too much.

She was tired of railing against those instincts and she resolved, as she had one hundred times before, that she had to put a stop to the antics. Relena sighed quietly before pulling back her bedsheets and startling a little in surprise. Nestled against her pillow lay a small, brown teddy bear, a black ribbon tied around its neck. She picked it up, immediately overwhelmed by the drift of Duo and Heero’s pheromones off the toy’s plush fur; comfort welled within her, breaking down the dam of her longing and making it flood her senses.

Relena tried, but couldn’t contain the sob that tore out of her, tears already breaching and trailing down her face.

“Princess?” Duo’s voice was almost admonishing as he stepped inside the room, but Relena stepped back, crying openly now. “Relena, what’s wrong?”

“Don’t!” she yelped, stepping away again and stumbling back against the bedside table. She kept the bear clenched inside her shaking hand, her instincts making the thought of putting it down intolerable. “Oh,” she finally cried, throwing it onto the bed so she could bury her face in her hands, “I can’t do this anymore.”

Duo and Heero glanced at each other, both bewildered, neither knowing exactly what to do next. Relena’s distressed scent soon carried through the room, making each of them fidget on their feet.

“I’m so sorry,” she breathed between sobs, sitting on the edge of the bed and resting her head in her hands again. “I can’t do this.”

“Do what?”

“This!” she gestured at the bed and then at Heero as he shifted, hiding the flowers he’d been carrying behind his back. Relena groaned, collecting herself just enough to look them in the eye. “You are both so good,” she said mournfully, “but I can’t let you keep doing this.”

Both alphas glanced between each other before Heero spoke. “Why not?” He crossed the room to put the flowers down, carefully straightening the leaves so they wouldn’t crease. It gave Relena a beat to strengthen her resolve, even if seeing the burgeoning sadness on their faces broke her heart.

“I’m in love with you,” she said quietly, watching as Duo’s concerned expression finished shifting to deep disappointment. “I’m in love with both of you.”

Heero stopped completely in his tracks, staring at the flowers before he turned just his eyes toward her. “For how long?” Relena may have missed Duo’s immediate rebound into surprise, but Heero hadn’t, and he let his attention pass between them.

Relena shuddered a sigh. “A long time. I wanted to tell you-”

“Why didn’t you?” Duo was bewildered now, shifting on his feet. “We would’ve-”

“I was going to,” Relena continued; the dam had burst, and the words kept flowing out. “I was going to, once you both were with Preventer- once you both started seeing me, for your ruts.” She paused, wiping her tears off her face with her fingers. Heero stepped forward and took a tissue out of the box on top of the bedside table and handed it to her; she let out another quiet sound, caught between a sob and a laugh.

“I made a plan to tell you…and then you two were together,” she said, “finally.” Tears welled up in her eyes again as she looked up at them. “You were happy. You didn’t want-” she caught herself, looking back at the floor. “You were happy.”

Duo stepped closer, watching Heero before he turned his eyes back on Relena. “We are happy.”

“I know.” Relena nodded, her voice and her scent betraying the pain of her resignation. “I already almost ruined it once. I promised I couldn’t let that happen again, but I’ve been weak. I’m sorry.” She looked at them both with so much care and consternation it made the alphas breathless. “I’ve been so selfish,” she said, “but this was the only way that you wanted me.”

“You never ruined anything,” Duo said, at the same time Heero muttered his own denial.

“Then why was I a secret?”

Both alphas winced, glancing at each other before Duo sighed and rubbed a palm over his chest. “I couldn’t stand thinking either of you were fucking anyone else,” he admitted first. The words alone made him grimace as his scent shifted just from the recollection of his jealousy, and Heero’s did the same.

“You were never a secret because we didn’t want you,” Heero said. “You were a secret because we didn’t know how much we both wanted you.”

“Because I’ve made you.” Relena’s voice was low, her gaze focused on the tissue in her hands. “I should have stopped this a long time ago - once I knew I had these feelings for you. My omega is triggering you,” she said, her confidence wavering when she looked up to see both alphas shaking their heads.

“Relena,” Duo said quietly, sitting down next to her, reaching one hand to rest over the top of hers. “You never made us do anything,” Duo reassured her. “We came to you, remember?”

She nodded, turning her head as Heero sat down at her other side, wrapping an arm around her back. Relena tensed as he leaned in, pressing a kiss to the edge of her jaw as he murmured “how long have you been off your suppressants?”

The omega immediately flushed, looking anywhere but at Duo’s face as he started grinning.

“Since you first asked me,” she admitted breathlessly. “I…” her voice trailed off as she glanced between Duo’s eyes and his lips before she caught her breath, “I thought if I could control my feelings, then maybe I could do it.”

“Have our baby?” Heero asked, and the eagerness in his voice made Relena and Duo turn to watch him, soaking up the softness as he waited for her to answer.

“Have your baby,” she whispered, her expression breaking as her tears came back. “I didn’t know if I could give you that, if you didn’t want all the rest.”

“We want all the rest,” Duo said, leaning in to rest his head against hers. She sighed, leaning into the contact as Heero pulled himself closer to her. “You love us?”

“Of course I do,” she said, opening her eyes to look at him before she reiterated, “Both of you.”

“We love you,” Heero murmured over her shoulder, leaning in to kiss her cheek.

Relena smiled gently before she caught herself again, her last salvo of seriousness coming over her features. “I never want to come between you,” she started, but Duo laughed.

“Oh, you’re going to come between us,” Duo said, his voice betraying his interest, “and on top of us, and underneath us.” He chuckled as he kissed Relena, feeling her pheromones start pouring off her in earnest. “First, we’ve got to get you into heat.”

Chapter Text

“I haven’t been in another heat since the first,” Relena murmured, leaning into Duo’s touch as he pulled her closer, and she felt Heero smile against her skin as Duo quickly drew his face away to stare at her intently. 

“You haven’t?”

“No,” she said, a pink flush having risen in her cheeks. “It’s a nuisance, and I didn’t want to risk it, especially once…”

“Once we started taking you,” Heero offered, still kissing her neck, and Relena scoffed through her nose. 

“Yes,” she agreed, “something like that.” She watched Heero reach and take Duo’s hand in his, drawing him back to reality. Duo glanced at where their fingers touched before he swallowed and looked back to Relena’s face cautiously. “What is it, Duo?”

“Nothing,” the alpha breathed, clearing his throat and breathing a laugh. “I’m just surprised that you've never passed a heat with anyone before.”  

He knew better than to think that his hesitation would get past Relena - she was as shrewd to his half-truths as Heero was. His partner watched him with the faintest grin pulling at his lips, one Duo knew meant the other alpha was feeling downright mischievous.

“Duo,” Relena purred, leaning in to press a kiss to his jaw, “it's true. Nobody's ever knotted me." She smiled the same fiendish smile Heero had, watching as Duo shifted in his spot at the end of the bed, clearly trying to relieve growing pressure in his pants. “Heero,” she said, turning to the other alpha, “does Duo seem well to you?”

“He seems like he wants to be your first,” Heero replied, making Relena laugh out loud. 

“I do not,” Duo started, but he stopped when two sets of blue eyes locked on to him, brows raised, waiting for the rest of his lie. “Come on,” he said, leaning back and sighing. “I’m just considering the facts… if you’ve never taken a knot-” he stared at Relena’s neck just a little too long before looking away again- “then it does change things a bit. The odds aren’t as good we’d get you pregnant right away.”

“Then we should practice,” Relena replied smoothly, undeterred by Duo’s attempts to dodge her attention, grasping the front of his shirt and pulling him in to kiss her. He groaned as she traced his bottom lip with her tongue, quickly deepening their kiss. 

“Not here,” Heero had said, reaching out to Duo’s cheek and putting just enough pressure through his thumb to break their kiss. Duo’s reaction was completely driven by instinct - the sudden burst of pheromones paired with the glare he gave the other alpha made Relena gasp quietly. Before Duo or Heero could recover she was on her feet, stepping away from the edge of the bed. 

“Relena,” Heero started, but she shook her head.

“No,” she insisted, her furtive expression growing more concerned with each passing second. “I meant it. I’m not going to be the reason you fight.”

“It’ll be fine,” Duo said, and Heero nodded. “We can share.”

“Can you?” Relena asked, her eyes locked on Heero’s. Duo shifted again, feeling a brush of annoyance. 

“What are you worried about him for?”

Relena raised a brow before she finished considering Heero and looked at Duo. “You know that he… you two are very different,” she said carefully before she wrapped her arms around herself, squaring her posture. “When you’re with me.”

“We can handle it,” Heero said, standing and stepping close to her again. “But not here. At home.” He glanced back over his shoulder at Duo. “We can make a plan to trigger you once we get back to Earth.”

“Trigger me?”

“Sure,” Duo said, catching up with his mate’s line of thought. He brushed a hand over Relena’s hip before squeezing, taking the chance to kiss her cheek and rub his scent gland over hers. “From how incredible you smell, I don’t think it’ll take much.”

Heero pulled at Relena’s other elbow, providing a slight counterbalance as she leaned into Duo’s contact, drawing her back to centre. 

“We’ll be back on Earth soon,” Duo muttered against the skin of her collarbone, enjoying the way she sighed into it. “We can play nice. Promise.” 

Duo had meant it all, but of course their best-laid plans would go awry one way or the other. The alphas were shamelessly invested in their plan to quickly trigger Relena back into a regular cycle - they had all waited long enough. If the small touches and gifts had warmed her heart, the continuous contact from the alphas was like putting a lit match to gasoline.

Their affections were no less sweet, but with their feelings out in the open, finally, they had to compete with passion. Duo and Heero's gracious outstretched hands to guide her into the elevator were the same ones that pinned her to the wall and kissed her senseless before it reached their floor. The alphas would still surveil her home but more and more often found themselves lingering around her bed, scenting her pillows and leaving their same mementos and trinkets. 

Relena was hardly opposed to it all, the density of her work and social calendar withering day by day as she found herself spending more of her time with her alphas, or thinking about them - and thinking about them led straight to her instincts taking over. Relena would mutter quiet apologies as she sought them out, climbing into laps, dragging arms around her, stealing sweatshirts to let their scents linger with her around her home. The craving for their contact was unfamiliar to her, but never strange, her omega needs resurging when they had been long suppressed. 

After a few weeks of this, they were all growing a little impatient, all more easily turned on and frustrated with each lingering touch, each losing sleep, and wondering when nature might intervene.

Duo was recalled to Preventer for a few days, for a mission of such high importance he couldn’t say no. It had been a grueling few days working on extricating hostages from a rogue militant group a continent away from home. With no real way to communicate with anyone outside the mission, Duo was left to his thoughts, wondering if Heero was feeling the same constant, demanding instincts he was now that their omega had finally agreed to be theirs .  

When he finally got his personal effects back, he wasn’t surprised to see missed messages on his phone, barely getting to glance at them before Heero was calling him. Without any other indication, Duo felt his stomach drop, knowing why his mate must be trying to reach him.

“I think it’s started,” Heero had said quietly, and Duo held the phone against his chest for a second, to swallow the sound of his sighed curses as he multi-tasked, grabbing his bags and stepping into the jet that would bring him back to Brussels. “When are you landing?”

“Not until the morning,” Duo said, his disappointment snowballing. He swallowed, shaking his head. “Don’t let her suffer for it,” he added, hoping the bitter taste of the words didn’t linger in his tone. 

“Okay. We’ll wait for you,” Heero said, “as long as we can.”

Duo loved Heero, but he also knew what it would mean, being an unsuppressed alpha contained with an omega freshly returned to a heat cycle. The mission was successful, but nothing could make the flight take less time than it would take, though it gave him time to wrangle with the feelings of disappointment and jealousy that rose up in his chest when he thought of the two of them alone.

Once he arrived at Relena’s home, though, he knew he was mistaken - he’d thought too little of how determined they must be. As soon as Duo crossed the threshold of the front door, Relena’s scent was a bombardment. He breathed deeply, feeling it rile his alpha the way not even a fistfight could match, and he took the stairs by twos before slowing outside her bedroom. 

Once he arrived upstairs, he started to hear them, Heero’s indecipherable low tones followed by Relena’s muffled sobs that quickly escalated to wordless, keening sounds that made the blood rush to Duo’s groin. Duo sighed, resting his head against the bedroom door as he listened to Relena come, grinding his teeth before he opened the door. 

He’d known what he expected to find, but this was certainly not it. 

Heero stood off the bed as Duo opened the door, dressed in a pair of low slung sweatpants and sweat trailing down his chest. He heaved a deep breath as he took in his mate. “Thank fuck,” he muttered, reaching down and running a hand along Relena’s back as he wiped his face with the back of his other forearm, still stepping toward his mate. 

The sight of Heero so riled, exuding alpha pheromones, roused Duo’s instincts even farther, and he gritted his teeth as Heero stepped close to him. Heero wrapped a hand around Duo’s shoulder and another around his neck, pulling him into a deep, sloppy kiss. Duo had a half-moment of instinctual recoil as his alpha raged at Heero’s demanding approach before it was smothered, mollified by the taste of Relena on Heero’s skin, the overwhelming smell of her pheromones shared between them as they kissed. 

They snapped out of it quickly when Relena keened again quietly, sinking down onto her elbows. If her taste on his mate’s lips had been enticing, the omega presenting for them had Duo by the throat. “Jesus,” he whispered, feeling Heero shudder the same way he was, watching her. 

Duo stepped around the edge of the four-post bed to better see her. She was similarly drenched in sweat, her hair pulled back in the messy remnants of a bun of some kind. Duo gave a quiet laugh as he followed the line of her body up to her wrists, realizing they were trapped beyond her head.

“Handcuffs?” Duo asked, stepping to where he could reach Relena. The silver glinted from both of her wrists, the chain wrapped around the post of the bed. She sighed and sobbed as she pulled at them, wordlessly whimpering in frustration with them. 

"She was relentless," Heero said by way of justifying them.

“Heero,” Duo said more demandingly now, “where are the keys?”

“I threw them out the window,” Heero answered, speaking like he was just saved from drowning. Taking a deliberate step back from the bed, he took a deep breath. “I’ll go find them.”

Before Duo could say more to protest, Heero lurched from the room, leaving Duo alone with their omega. “Princess,” he said quietly, stepping closer to her and putting his hand on her shoulder. Her skin was fever-hot to the touch and she groaned immediately as he touched her, sinking further until her chest hit the bed, presenting for him.

“Oh, fuck,” Duo breathed, shedding off his jacket immediately and reaching into the pocket for a pick. “I’ll get you out of them, just… fuck. Sit up first.” 

Relena didn’t shift right away, and the alpha rankled at being ignored; Duo reached forward and grasped the chain of the handcuffs, dragging it up the post of the bed. The sudden force pulled her forward, making her crawl awkwardly up onto her knees. She sobbed as he did, but the shift in her position made her focus on him again, her eyes lined with frustrated tears. A piece of black body tape covered her mouth, leaving her with no way to beg him but sobbing at him again, clenching her thighs together. 

“Move in,” Duo said, and this time she obeyed, shifting on her knees so he could sit beside her and begin picking the handcuffs. They were standard issue, and presented no real challenge to him in any other circumstance, but his hands had started to tremble and sweat as her pheromones drenched him and the air. He shifted on the bed and Relena moved to straddle his leg, immediately taking advantage of the friction and grinding against his thigh, groaning gratuitously while she did. 

“I can’t believe you waited,” Duo said incredulously, almost angry at the height of her desperation, but she looked at him with so much affection it drained him of any frustration. The cuffs clicked as the lock gave way on one side, and Duo freed her hand. She immediately wrapped it in the neck of his shirt, using the leverage to shift her hips and press her upper body against his, groaning at the friction. 

“What on earth were you saying to him?” Duo murmured as the second cuff released. Relena leaned back to give him a glance so charged that he laughed breathlessly before reaching for her hip and raising his knee slightly. The effect was immediate, the friction making Relena close her eyes and moan as he carefully pulled the tape off her mouth.

“Please, Duo,” she begged as soon as she could. “We waited for you.”

“You shouldn’t have,” he admonished again, although his edge was starting to fail. Relena worked her hands under the edge of his shirt.

“We wanted to,” she insisted, “but please, Duo. Please. I need you.” She pressed herself against him again, groaning as he ran his hands over her back. Relena fussed with the edge of his shirt before he shifted, extracting himself from underneath her and standing next to the bed. 

She panted and reached for him, pulling him back and trying to manage the button of his slacks with shaking, sweaty hands.

“Babe,” he said quietly, pulling his shirt over his head as stared down his body at her, watching her struggle. “Relena.” 

She was so single-mindedly focused, the omega gasped as he grabbed her wrists, pulling her hands up to his chest. “Stop,” Duo said, reaching and undoing his pants quickly, pulling them down off his hips and kicking them off along with his socks. “I’ve got you,” he said, reaching to stroke his already hard cock, precum leaking from the tip, ready to slick his skin.

“You do,” she said, her voice a bit hoarse, and he nodded, climbing into bed next to her, reaching and pulling her back into a kiss. It turned from comforting to scalding immediately, Relena opening her mouth to him as she wrapped her arms around him, pulling him overtop of her. He was eager, their pheromones mingling, creating a feedback loop that made Duo’s heart pound in his chest. 

He groaned at how easily she opened up for him, lying under him and spreading her legs, wrapping them around him, and Duo hesitated for only a second. “Relena-”

“Please,” she panted, pressing her hips up toward his. “Duo, you have to knot me.” As soon as Relena said it, Duo relinquished whatever notions he had about holding back. “I want you- I need you to fill me,” she kept murmuring, her words pressured, gasping as he took hold of her thigh and pressed her leg back, exposing her body fully to him. 

Duo groaned as he stroked himself again before pressing forward, letting the head of his cock brush over Relena’s apex, gathering slick from her skin. The bit of contact alone made her cry out, fresh slick gathering at her entrance. “Duo, please,” she said again, her pheromones taking on an edge that matched the desperation in her voice. “Please, we waited.” 

“You did,” Duo said, and he aligned their bodies and pushed himself inside her. Her relief was immediate but brief; Relena caught her breath, propping herself onto her elbows to stare down where their bodies joined. Duo moved slowly, drawing out before pushing back inside her, watching and feeling the omega preen at being filled by her alpha. “You shouldn’t have waited.”

“Make it up to me,” she said, and Duo pulled on her hips, shifting their bodies so he could lean over her and kiss her. After a few more strokes, he felt the rhythm of her breathing shift; Relena pulled out of their kiss and groaned his name, her body clenching around him. 

“Already?” Duo asked, shocked, and by the time Relena nodded she was over the precipice, an orgasm tearing out of her and making her shudder. Duo leaned in and kissed her neck but didn’t stop or slow his own pace, fucking her through her orgasm and leaving her gasping for breath. The release of her scent made him feel lightheaded, and Duo shifted again, nudging her hips open with his and relishing the sounds she made as he drove himself into her harder. 

If it wasn’t for the scent of him, Duo wouldn’t have even known Heero came back into the room - he was so focused on the omega under him, the sounds he coaxed out of her, the rhythm of skin on skin as Duo kept chasing his own pleasure. Heero shed his pants and stepped up to the bed slowly, half-hard and eyes already dark with want, his gaze shifting between watching the alpha or the omega. 

Duo felt the possessive rise of his alpha as Heero came closer but he fought through it, feeling his knot start to fill. The first time it forced a slight stretch at Relena’s opening she gasped, fighting up onto her elbows again. 

“Duo,” she said through a groan, fighting between holding herself up and holding onto him. “Duo please, please. Knot me, I need it-”

“I know,” he said, feeling his knot catch again. “I’m going to give it to you. We’re going to fill you up so good.” With her hands all over him, her breaths catching and gasping as she moaned, Duo thrusted in and out of her twice; the third time pushed his knot inside her, coming as soon as it tied them together. Like the cum he was releasing deep inside her was its own aphrodisiac, the omega came again, fighting to catch her breath.

Relena said his name again as she finally came down, reaching to wrap her arm around his neck and pull him into a kiss, both of them relishing the feeling as he filled her with his seed. He took a deep breath and panted, leaning back to look at her. Slick with sweat, Relena smiled at him, catching her breath before she trailed her fingers over her skin, settling just between her hip bones over the small swell she could feel and see at the bottom of her belly. 

“Amazing,” she said quietly, shifting her hips; as she did, Duo leaned in again to kiss her. The afterglow was incredible, and intoxicating enough that they both startled when Heero slowly climbed into the bed next to them.

He held back an outright snarl, but Duo’s instincts raged as he covered Relena with his body; in the process, he drove his hips against hers again. The result was instantaneous, the swell of his knot moving where she could feel it inside her and under her hand, and the raw sound she made as pleasure coursed through her redirected Duo's instincts back to her.

“Do that again,” Heero said, shifting on the bed, his cock hard and waiting between his legs. He leaned forward, pressing his face into Duo’s neck, taking the chance to breathe in his mate’s scent. “Fuck her with your knot.” 

Groaning, Duo grasped Relena’s hips, forcing her legs wider with his and making use of the bit of room he had, pulling his knot against her entrance before forcing it back into her. The omega cried out as the head of his cock pressed against her end, slick and cum starting to pool on the sheets underneath them. 

“Duo,” Relena gasped, and the alpha hesitated, but stopping the intense pleasure of friction against his knot, and the way she cried out every time he moved was unbearable. “It’s so much. It’s so much-” 

“You can take it,” Heero said, and he shifted his attention back to the omega. She watched Heero, rapt, as Duo kept making short, rough thrusts inside of her. It felt like every thrust coaxed another surge of cum from his sac as she clenched around his knot, her body milking him instinctively. 

“Come on,” Heero said, and Relena shook her head, hands reaching for them - one wrapped around Duo’s arm, her nails biting into his skin, the other reaching for Heero. Heero took her hand in his, using the other to pin her to the bed, resting the edge of his palm just under her throat. “Come on his knot again.” 

She did, eyes rolling back as it moved through her, and the noises Duo’s efforts coaxed from her were choked and desperate as the omega clung to them both for dear life. It took time for her to reopen her eyes and when she did, Relena looked up at Duo through her lashes. “No more,” she almost whispered, and Heero breathed a laugh as he shifted his grip.

“There’ll be more,” Heero said, his tone somewhere between a promise and a warning. He took Relena’s hand and pressed her palm around his cock, letting her start pumping his erection through her fist as they waited for Duo’s knot to release. Duo watched with eager eyes as Relena worked Heero’s thick shaft; the head of his cock was purple and looked aching, and he groaned with a mix of relief and frustration as she touched him.

Duo felt an interesting surge of pride, watching his mate, amazed that Heero had simply watched and waited while another alpha knotted an omega in heat - an omega Heero wanted, too. “I love you,” Duo said to them both, and Relena flushed as her body tightened around him again. Heero bridged the gap between them and kissed Duo languidly - the way they’d learned they needed to, to keep their alphas at bay - waiting for their bodies to slowly separate. 

All of them gave a sigh of relief as they did, moments later. Duo pulled away from the omega, leaving a pool of his seed on the sheets, and his pride rallied again. 

They had known with two alphas, there may be twice the choking, driving pressure on Relena’s instincts to satisfy them, and it appeared that was the case. Within moments of being freed from Duo’s knot, her skin was flushed rosy pink again, and she sighed, then whimpered as her body clenched hard around nothing. 

“Heero,” she said, but it was all she needed to say; Heero guided her forward onto her knees, and Duo shifted out of the way to watch the other alpha gently, firmly, press her into a presentation pose. The post-knotting malleability was still rolling through her and Relena rested her head between her arms, sighing before Heero lined himself up behind her hips and pushed his considerable girth inside her. 

“Oh, fuck,” she groaned, reaching back to wrap her fingers overtop Heero’s on her hip. The alpha pushed to a demanding pace almost immediately, and Duo sighed, feeling his cock twitch - he’d never gone soft, the swell of his knot not even totally gone. The sight, smell and sound of Heero fucking someone else was something Duo had always avoided thinking about. With Relena, it was something else entirely, and Duo sat back, reveling in how beautiful they both were, and both his . 

“You smell so incredible,” Heero said, reaching out to wrap his hand in Relena’s now mostly unbound hair, putting one hand on the back of her neck. The way the omega took his pace was perfect, pushing back against Heero’s hips. 

Heero pulled Relena’s hair by threading his fingers into it at the root, shifting his other hand around to the front of her stomach to help force her up. She reached for Duo as he took her chin in his hand and kissed her. “It’s okay,” he said, brushing a hand over Heero’s. “You don’t have to do anything. We’ll take care of it all.” 

Relena nodded, still breathing and gasping and moaning through Heero’s continued hard fuck as Heero let Duo take hold of her hair, holding it back away from her face. Without hesitation, the omega opened her mouth as Duo positioned her, holding the base of his hard cock in his free hand and brushing it over her lips. 

Both alphas groaned with the edge of a growl when Duo started fucking Relena’s mouth, shifting the rhythm of her breathing. He heard Heero curse under his breath, shifting his position as his knot started to form, pushing himself in even deeper - a moment later, Duo pulled back on Relena’s hair. He smiled at the omega’s frustrated glare as she reached for his cock, but he shifted out of the way. Heero outright growled as his knot caught for the first time, thoroughly distracting Relena from trying to argue with Duo any further. 

“Take him,” Duo said, panting again, rock hard from watching them. He put a hand to the back of Relena’s neck, pressing her down into the bed as Heero knotted her. Both of them groaned through the first wave of their orgasms, the omega tremoring and holding her breath until Heero brushed a hand down her back, murmuring a reminder to breathe. She gasped his name, her scent surging as he filled her; Heero reached under her belly, groaning and releasing inside her again as he felt the swell of his knot through her skin. 

Thoroughly fucked, Relena sighed, staying low on the bed even once Duo took his hand off of her. Duo grinned at Heero, and he wasn't surprised when Heero smiled back. They'd sated her heat for now, but there would be more to come. 

Chapter Text

“You know, we’re pretty lucky,” Duo said quietly, tracing a finger along Relena’s shoulder as he watched Heero do the same along the side of her hip. Heero nodded, shifting to lie alongside the sleeping omega. “That was quick, though,” Duo added with a tinge of disappointment. He brushed some of Relena’s fringe along her cheek; he’d carefully drawn the rest of her hair up into a braid after getting her out of the shower. Duo smiled, thinking about how they’d fucked her senseless in there, too - he wasn’t sure her feet had hit the floor the entire time they’d been out of the bed.

“It’s not over,” Heero said, sliding his hand along her side. Relena stirred slightly, but didn’t wake.

“No?”

Heero shook his head a bit, leaning in to lay a kiss over Relena’s neck, breathing in her scent while his palm slid up to cup her breast. Duo watched his mate’s dark lashes drift closed, warmth resurging under his own skin. Relena wasn’t waking, but her body was still responding, though her pheromones were tame compared to the onslaught the afternoon before. Rolling her nipple between his thumb and fingers, Heero exhaled hard, shifting his hips.

“We can trigger her again,” he said, glancing up at Duo, his eyes pausing along the way to take in the other alpha’s half hard cock - Duo wasn’t protesting. Relena lay on her side facing him, her back nestled against Heero’s body, and Duo drew himself closer, sliding his arm behind her head. Her brow furrowed a little as he shifted her head into the crook of his elbow.

The omega had been properly exhausted, more from the half day of resisting her heat than the other half spent fucking the rest of those pheromones out of her system, punctuated with her using both alphas for body heat and comfort. She still didn’t wake when Heero and Duo’s hands continued roaming her body, although they were both rewarded with occasional small gasps and exhalations.

Shifting again and resisting the urge to touch himself, Heero reached to press his hand between Relena’s legs, his fingers grazing over her sensitive skin.

“Heero, wake her,” Duo warned, but Heero rolled his eyes, nestling his head into Relena’s skin and nipping her on the shoulder. Duo wasn’t sure if it was the bite or the motion of Heero’s hand sliding his fingers down her folds and then along her entrance, but the omega moved again, her brows drawing together, her gasp more pointed than before. Duo watched, feeling his cock twitch as he saw Heero’s fingers tease along the soft skin one more time before tucking them inside her.

Her eyes fluttered and she tried to turn over, spreading her legs and sighing while Duo held her, trailing his free hand down her body. He took two deft fingers and slid them alongside her clit, spreading them to expose her a bit more. Heero outright growled, pumping his fingers up to where they met his palm.

“Relena,” Heero said, and she turned her head toward him, her eyes opening with an unfocused gaze. “Let us fuck you awake.” She nodded, turning further onto her back, her legs already relaxed. Each alpha adjusted her, Heero pinning one leg open with his elbow as he continued fingering her, slick already starting to spread along his fingers. Duo shifted his knee, propping her other leg over it.

Duo shifted his trapped arm, tilting Relena’s face up towards him, leaning in to kiss her. She readily let him brush his tongue along her lips before sweeping it into her mouth. Her scent started to shift, releasing further and further into the room with every slick-soaked sound of Heero’s fingers pressing in and out of her. Duo broke the kiss to nudge her face to the side with his, licking her neck.

With a shift of his hand, Duo pressed a few fingers to Heero’s wrist, knowing better than to try and impede the other alpha - Heero looked up at him, pupils blown.

“Let me join,” Duo said, sliding his hand along his mate’s, aligning his finger’s along up to where Heero’s were still part-enveloped inside the omega. Her hips shifted, trying to grind her body against Heero’s hand, but Heero withdrew his fingers and threaded them against Duo’s instead. Duo groaned as his lover’s slick covered fingers brushed along his own, their two forefingers pressed together, palms pressed together before they brought all four of their fingertips to her entrance.

They were careful, and she was soaking wet, her instincts working overtime to prepare her for the potential of two rutting alphas, but her eyes still flashed open as they pushed their fingers inside her. Relena gave a gasp followed by a round, grateful moan. She struggled up onto one elbow, looking down her body to where their hands were joined, pushing and pulling together in and out of her.

“Oh my god,” she groaned, and Duo smiled as he pressed another kiss into her neck, Heero leaning in to do the same on the other side.

“We’re not finished with you,” Heero said, and Duo breathed out hard as Relena tightened around their fingers at the ‘threat’. Heero brushed his teeth over the omega’s throat, the skin across her neck becoming flushed.

She moaned again with each thrust of their hands; Heero threaded his free fingers into the base of her braid, leveraging it to pull her head back down overtop Duo’s arm, pinning her to the bed. Relena’s body was awake now, her hands reaching for them, brushing her nails across their chests and grasping at their arms.

Understanding each other so well, the alphas pulled their twined fingers from inside her, both glancing at the other and smiling when she gave an uninhibited whine at the loss of pressure inside her. A small adjustment and they were back at her entrance again, the back of Duo’s hand in the palm of Heero’s, their fingers pressing back inside her.

Duo curled his fingers inside her, eliciting a pitched cry from Relena that put him against the edge, his instincts roaring to life and demanding that he claim her. Groaning, Duo leaned into her neck, pressing sloppy kisses against her scent glands.

“Mark me,” she groaned as much as said, reflexively trying to close her legs and control the firm, driving pleasure as the alphas pushed their fingers inside her. Heero pressed her leg open again with his elbow, the hand in her hair not relinquishing an inch, and both alphas groaned as she tightened around them, nearing the edge.

Both of them had taken great pains to avoid marking her in the past, knowing she hadn’t belonged to them - any marring on her skin could be taken as a bond, would have been proof positive that some alpha had claimed her. Duo didn’t wait for her to make her request again, leaning in and biting against her neck just as Heero pressed their fingers up harder inside her.

Relena came hard, crying out each of their names, clenching her legs around their arms, her hands pressing against their chests. Duo withdrew from her first, brushing his hand along the inside of her thigh, supporting her leg as her body trembled. Admiring the strawberry-coloured mark he’d left on her neck, he pressed a few kisses to her cheeks before swallowing the last of her moans, their kiss open-mouthed and heated.

Heero took advantage of Relena’s satisfied and boneless state, turning her onto her side facing away from him. With a few movements the head of his cock was pressing between her thighs, gliding along the slick still clinging to her skin. She threaded her hands over Duo’s shoulders, pulling him into another kiss as Heero gripped her hip, shifting to press his cock inside her.

“Heero,” Relena breathed against Duo’s lips, her eyes drifting closed as she smiled, basking in the pleasure of being filled. Duo clung onto her, splaying his hand between her shoulder blades from where his arm wrapped around her, the other reaching down to wrap under her knee, dragging her leg up over his own hip.

Heero gave a satisfied growl at the change in angle, shifting his hips to start fucking Relena in earnest. Duo felt Relena’s heat starting to rise, her skin growing warmer everywhere they touched. He wanted too many things at once, but groaned in relief as Relena’s hand left where it had gripped his shoulder and moved to wrap her dainty fingers around his cock instead.

Duo groaned out a curse as Heero shifted up onto his knees, pressing Relena’s thigh further up onto Duo’s hip. With the extra leverage, Heero’s pace became deep and relentless, the sounds of their skin smacking together like music to Duo’s ears. Relena gasped and moaned but kept up her careful attentions on Duo, kissing him, sliding a few fingers between her legs to wet them with slick. Bringing them back, she brushed them over the head of his cock, making him groan and thrust his hips into her grasp.

“Oh, fuck,” Relena groaned, “I’m-” Heero sealed his lips over hers, swallowing the last of her words, but his hips slowed. She tolerated the kiss a moment longer before she broke it; Heero pulled his cock out of her, his chest heaving as he caught his breath.

“Heero,” she said, irritation crossing her face, but Duo recognized the look Heero gave him, and he eagerly rolled Relena onto her back, positioning himself between her hips. She had no time to keep protesting as Duo slid an open palm across her pussy, earning back her undivided attention.

“More?” he teased, and she nodded, tilting her hips up for him; Duo held her leg just above the back of her knee, the other hand stroking his cock before he angled himself against her, pushing inside her. They both groaned as he pushed partway in before withdrawing, letting his length get wet with slick before pushing in to the hilt.

Her core was hot and tight around him, and with each thrust he felt her temperature keep rising along with the ringing keen of her cries. Heero stayed sitting back on his knees next to them, watching while Relena palmed her own breasts, her expression taking on the intoxicated, unfocused haze of heat.

Duo smiled as Heero leaned in to kiss him, feeling his mate’s lips against his own while he pumped into their omega, letting the sounds and sensations take him.

He and Relena both gasped when Heero reached between them, pressing his hand down on her belly just above her pubic bone. The shift in pressure made her cry out, scrambling up onto her elbows.

“Please,” she gasped, and Duo had been all too happy to continue, but Heero pressed a hand to his chest.

“Stop,” he said, and a spiral of instincts collided with both alphas. While there’d been no Command behind his tone, Duo still bristled at Heero’s intrusion; his balls ached to empty, the burden of his own orgasm already crawling down his spine. Heero leaned in, brushing his cheek against Duo’s in a very rare show of supplication from the fellow alpha. Duo latched onto it, still catching his breath as he held still, Relena growing more and more distressed as he held her knees apart, pinning them overtop his thighs.

Duo pulled out, making Relena outright growl in frustration; she reached between her own legs, desperate for release, but Heero was faster, grabbing her wrists and pressing them both above her head. He leaned across her, his cock bobbing, hard, near her face.

“Heero, let go,” she said, pulling against his hold. As she moved to reposition her legs for more purchase, Duo grabbed hold of them again, holding her hips open. Heero manipulated both her wrists under the palm of one of his large hands, using the other to brush a thumb over her lip. The look on her face was so flushed and frustrated, Duo laughed in surprise that she didn’t outright bite Heero. The alpha moved on, running his knuckles across her nipple, making her whine and arch her back into his touch.

Duo shook his shoulders out, his alpha instincts surging as Relena’s scent shifted again.

“Sit back,” Heero said, still holding her wrists above her head. “Let her suck you off.” As much as both of them wanted to bury their cocks in the omega and fill her, her heat had still not triggered back to its full potential. Relena’s flushed cheeks grew a little redder as she fought against Heero’s hold - he let go once Duo was settled at the head of the bed, and she eagerly knee-walked up to him. She tried to climb into his lap but Heero stopped her again, grabbing onto her hair and her arm.

“You heard me,” he said, and she leveled a glare at him.

“You fuck me, then,” she demanded, and he smiled - as he leaned in to kiss her, she pulled his lip between her teeth, making him hiss and push her away.

“Him first,” Heero insisted, and Duo was glad; he stroked himself, his cock aching and weeping, eager for relief. Relena turned her attention to him, kissing his fingers before pressing her lips along the shaft of his cock, dragging the tip of her tongue along the underside of the head.

As soon as she licked her lips and opened them to envelop him, Heero wrapped his arm around the back of her neck, making her moan. Lightly scruffed, Relena was under Heero’s control, and he used it to his advantage, making her suck on Duo shallowly until the other alpha started to rile. Duo reached for Relena’s hair himself, but as he did, Heero pressed her head down farther, making her take Duo’s cock to the back of her mouth; on the next push down, Duo’s cock slid past her tongue and into her throat.

She had sunk far enough into her heat that her gag reflex was calmed completely, and Duo could feel her try and fail to moan around him as his cock filled her throat. Groaning, he thrusted up to meet the rhythm Heero made, pushing and pulling her. Heero dragged her up to catch a breath through her nose before pushing her down again; Relena’s tongue made all the extra friction it could, saliva dripping from her lips down Duo’s skin.

Duo put his hand over Heero’s as he groaned. “Fuck, I’m almost there-” His orgasm broke through, cum spurting straight down the omega’s throat as Heero pinned her there, her nose brushing against the dusting of hair at the base of his cock.

“I can’t wait until the pregnancy heats hit you,” Heero growled, pulling her hair until she released Duo’s cock with a satisfying pop. “I want to see if we can make you come just by fucking your throat.”

She moaned, her fingers circling her clit, having escaped his notice while Heero used her to please his mate. “Please,” Relena said, and the word was like a beacon for both their alpha instincts. “Please, just fuck me.”

“‘Just’ fuck you?” Heero practically preened, and this time she didn’t rise to his bait, too far into her heat now to stop it. Duo smirked at Heero’s plans coming to fruition - the alpha’s seed hitting her empty stomach would further trigger her heat, her body demanding to be knotted and filled in the right place.

“Knot me, please,” she said, laying her head down against Duo’s thigh, the position propping her ass in the air, presenting for them. “Please, I need it. Fill me again..”

Heero watched Duo over the omega’s shoulder, already running his hand over the length of his shaft, and Duo nodded - temporarily sated, he brushed Relena’s hair over her shoulder and let his fingers trace over her skin. “Heero’s gonna give it to you,” he comforted, watching the alpha align their bodies and push into her without hesitation.

Between the pheromones and the previous denials, Relena couldn’t withstand the pleasure - as soon as Heero shifted his position, pressing a palm against the small of her back, the omega succumbed to another orgasm that left her gasping for breath.

“Fuck her through it,” Duo said greedily, although Heero needed no encouragement, pushing into her with enough force she braced herself against Duo’s body, her lips against the skin of his hip muffling her cries. The alpha’s knot swelled quickly and Heero pushed it inside, wrapping a second hand around the front of Relena’s throat and leaning in to bite hard over her scent gland.

Watching both of them fall over the brink of an orgasm together was one of the most beautiful things Duo had seen, and he took it all in, breathless himself once they finally started to recover. He was hard again before Heero even let go of Relena’s neck.

Heero inspected the bite he’d left, and Duo could see the way his mate prided himself, his knot still pressed deep inside the omega. Waiting just long enough for his knot to pass her entrance before pulling out of her, Heero groaned out loud as he did, watching the rivulet of his seed and her slick drip out of her.

Still, her heat was not sated, and she lifted her head, peering up at Duo with need still shining in her eyes. “Duo-”

“Come here,” he said, helping her climb on top of him. She was so slick with the evidence of Heero’s release, Duo slid inside her easily as she positioned herself over him. Duo let her sit on his cock for a moment, her hips making lazy circles against him as she caught her breath.

A few stray strands were coming loose from the braid he’d put in her hair, clinging to the skin of her face, and her lips were swollen from having pleased him not long before. She was beautiful, and Duo ran his hands over her waist before leveraging them to lift her a little and letting her settle back down until he was fully notched inside her.

“Fuck, Duo,” she said, letting her palms fall against his chest, her hands clenching and pressing her nails into his skin. “Oh, god-”

“We’re right here,” Duo said, pressing a hand against the small of her back again; the bit of pressure almost immediately made her collapse against his chest, as close to presenting as she could be while still keeping his cock buried inside her. With that change in position, Duo could lift his legs, pushing his cock up and into her.

He was rewarded quickly with her gasps and moans, the slick, rhythmic sound of his length sliding in and out of her pussy adding to the sensational overwhelm. Duo came back to reality just as Heero got into position behind Relena - his fingers teased along her pussy while Duo fucked her, making her tighten and drawing a guttural groan out of both alphas. Duo paused, waiting to see what Heero intended, pushing down the instinct to roll Relena under him and keep her to himself.

“We’re both going to fuck you,” Heero murmured, and Relena gave a shivering sigh as she nodded. Heero pressed the head of his cock along the bottom of Duo’s, slick coating them both and making it easy for him to slide it into her entrance.

The pressure was right, and Duo wrapped his arms around Relena, pinning her against him as he felt Heero’s thick thighs press against the back of his own. Heero pulled his cock out of the waiting omega, scruffing her again with one hand.

“Relax,” he ordered, and Duo felt Relena’s entire body lay lax against him, her breath coming in quiet, rhythmic keening sounds. Heero pressed his hand to Relena’s hip before letting go of her neck, using both hands to lift and then push her down, fucking her onto Duo’s length. The sensation was indescribable - Duo reached and stroked a hand over Heero’s hip before he brushed his fingers over Heero’s cock before taking it in hand. Stroking him in time with Heero’s manhandling Relena over his cock, Duo felt Relena shudder, knowing she was once again on the precipice.

He and Heero both muttered curses under their breaths as she came again, wailing while she pressed herself against Duo’s chest, Heero letting her hips settle against Duo’s. Both alphas brushed fingertips and kisses over her skin.

“Keep it together,” Heero said quietly while she gazed at him, fawning as she weakly tried to push herself up. “We’re not finished with you, yet.”

Duo gently took her back in his arms, her breasts pressed against his sweat-slicked skin. “Maybe she’s had enough.”

“No,” Heero and Relena both said, and Duo laughed, the rumble from it and the motion of his chest enough to make Relena tremble in his arms again. Heero lined himself back up against Duo’s legs, both of them shifting and moving Relena to make room so he could press himself into her waiting body again.

It was easier, this time, the omega completely pliable in their arms, and Heero watched Duo give a wicked smile as their cocks slid against each other, tightly contained inside her hot, slick-soaked pussy.

“Careful,” Duo murmured, letting his hands roam along Relena’s back, his own instincts begging for the release of burying his knot inside her again.

“She can take it,” Heero retorted, using his hands and his hips to drive into her roughly, demonstrating. Duo braced himself, feeling the new sensation of his mate’s hard length sliding across his inside their omega’s body; Relena groaned, cooing as he pushed back in again. “You like that?”

“It’s good,” she said, nearly slurring on the words, “fuck, it’s too much. It’s too good.” Duo thought the same, holding her against him as he braced them both against Heero’s pace, Relena’s body rocking against his with every determined thrust. Heero was plainly brimming with pleasure too, his breath coming almost like a laugh.

“You two feel so incredible,” Heero said, leaning in and kissing Relena’s shoulder and the top of Duo’s hand. Both alphas started to pant just as Duo realized Relena was holding her breath.

“Breathe,” he said, not intending to command her, but taking one more gasping breath was all she needed for her body to throw her into another orgasm, her whole body tightening around them. Heero groaned, slowing as he wiped sweat from his brow with the back of his hand.

Duo picked up the slack immediately, shifting his hips and thrusting upward into Relena, his own toes curling at the delicious friction between all their skin, Relena’s heat pheromones permeating everything.

“I’m close,” he warned, feeling his knot start to swell, and Heero pulled out, making room. Between Relena’s quiet begging and Heero timing it perfectly - as he would - Duo was quickly on the edge, pushing his knot up just as Heero pressed down on Relena’s hips, locking his knot inside her. The sudden change of pressure - being filled with a knot instead of filled with her alphas’ cocks - wrenched another orgasm out of Relena, and she shook with satisfaction as Duo held her against his body, pumping cum inside of her.

Duo watched Heero closely as the alpha sat up off his haunches - he grazed his fingers over Relena’s stretched entrance, drawing a growl out of Duo. Heero gave him a wordless glare, sliding a slicked fingertip over Relena’s ass. Her hole puckered quickly at the teasing touch, making her clench around Duo’s knot inside her; Duo groaned as it milked another release of cum out of him. Heero pushed forward, murmuring quiet encouragements to Relena, his one hand brushing her braid out of the way and rubbing along her skin as he worked her open with the other, pulling on the skin of her rim with his thumb, then pressing a slicked finger inside.

She raised her head to protest, but Duo pulled her into a kiss that immediately placated the omega, her heat still burning while one of her alphas was left unsatisfied. When Heero pushed a second finger inside of her she gave a quiet keen; Heero spread his fingers carefully, stretching her. Her body had prepared for the invasive touch, slick gathering along the tighter channel. When Heero notched his thick cock to her rim, he met little resistance, carefully working his way inside.

The pressure was intense, the omega trying to writhe with the added stimulation but being held in place so tightly with Duo’s knot and his arms she could only pant and cry out while Heero slowly fucked her. Duo groaned, feeling the continued stroking glide of the head of Heero’s cock pressing into Relena. With each of Heero’s thrusts Duo could feel the firmness of his own knot pressing from within Relena’s belly, trapped as she was against him, and it kept him hard.

Relena’s nails dug back into Duo’s chest and he winced, covering her hand with his as she gasped and begged. “I can’t, Heero- please, I can’t come again-”

“You’re going to,” Heero taunted, reaching out and brushing his fingers over the bite mark he’d left on her neck while he slapped his other palm against the skin of her asscheek. Grabbing her hip and roughly pulling her against him, Heero pushed her over the edge into another orgasm. Heero praised her, leaning in and kissing her shoulder as he kept his pace, keeping his thrusts shallow.

Duo looked up as Heero cursed quietly, gritting out the word before pulling out and stroking himself as he came over Relena’s back, slapping her ass again and adding to the pink flush on her skin. He collapsed roughly onto the bed next to Duo, immediately reaching his sweaty palm for Duo’s and intertwining their fingers.

Relena was quiet, catching her breath as her pheromones calmed. She sat up slowly, brushing any wayward hair off her face and heaving a sigh. Her body felt totally sensitized and exhausted, and she fought the urge to slap Duo’s hand away as he brushed one over her thigh.

“You okay, princess?” Duo asked, Heero following the question as he lifted his head, leaning against his elbow. Both alphas gave relieved sighs as she nodded, settling back down against Duo’s chest, laying a kiss on his skin before her eyes drifted closed again, her hand searching for and finding theirs, still intertwined, and pulling their hands closer.

Duo was on the edge of sleep again as Heero asked quietly, “when do you think we’ll know?”

Duo smiled, turning his head to look at his mate, leaning closer to him to kiss him. “Soon,” he said, “really soon.”

It had been soon, against the odds - although Heero would shamelessly joke that they’d beaten far worse ones plenty of other times - that they found out Relena was pregnant. Her scent had shifted within days, signaling their efforts had taken root, but the definitive test came a few weeks later. Heero had cradled the paperwork the whole drive home, all of them ecstatic.

They’d had months to figure out how they might handle which alpha might be the father, ultimately all having the same opinion: it didn’t matter. Their baby would be theirs, all three of theirs.

When their initial scans showed Relena carried twins, they had to acknowledge there had been some signs. Both alphas had felt a near immediate flush of satisfaction in the days after Relena’s heat, and it had not abated. Then, their rutting cycle came and went with no added drive, once, then twice.

Relena’s desires were also relentless, and though she’d tried valiantly for about two months, she needed to take the remainder of her pregnancy as a leave of absence from her work, unable to keep from causing some kind of incident or devote the attention she’d find acceptable between her ravenous, overwhelming need to feel both alpha’s around and inside her.

When the twins were born, it all made sense, of course. Two perfectly healthy girls, one with a crown of Duo’s auburn hair, the other Heero’s deep brown.
