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.
