Sirius stood in the hallway and folded his arms as he leaned against the wall. A soft smile grew on his face as he listened to the smooth, steady rhythm of Remus's voice as he read their four-year-old son to sleep.
It was a story that they'd read countless times, but Teddy never tired of hearing it - and as he listened through the wall, Sirius couldn't blame him. He knew he'd never tire of hearing that wonderfully warm and characterful voice. It had pulled him out of many dark places and low moods, and it often did the same for their son.
Slowly, Remus's voice trailed off, signalling that Teddy had fallen asleep. Sirius peeked through the door to watch as his Alpha tucked the young boy in and began creeping out of the room. They'd taken great care to decorate Teddy's room perfectly. There were stuffed animals and brightly coloured books lining most of the shelves, though Teddy's favourite stuffed dog always had pride of place on his bed.
The walls were painted to look like a peaceful meadow, and Remus had enchanted the ceiling to reflect the sky, bright and sunny during the day and starry at night. It was the kind of room they both wished they'd been able to have growing up and was just one of the many ways they intended to give Teddy everything they'd never had.
When Remus was close enough, Sirius wrapped him in a loose, comfortable hug and buried his face into the crook of Remus's neck. Remus grinned and pressed a soft kiss to Sirius's head. When he pulled back, he saw Sirius staring with wet, grey eyes at the small boy snoring softly in his bed. Teddy's short dark hair already looked sleep-rumpled despite having only been asleep a matter of minutes. His little hands clutched tightly to his duvet, and his face was pressed into his pillow. His soft lips parted slightly as his sleeping breaths whistled in and out.
Remus tilted his head and frowned.
"Did I tuck him in the wrong way?" He whispered. Despite the four years of practice, he still had very little confidence in his abilities as a father. Insecurity and self-doubt were never far from his mind.
His question snapped Sirius out of the thoughts that had occupied him, and his eyes sprang back to Remus.
"What? No," he sputtered.
"Okay," Remus sighed, though his confusion quickly outweighed his relief. "Then what's going on?" He wiped a rogue tear from Sirius's cheek and frowned with concern.
Sirius's lips curved into a smile. He caught Remus's hand in his and pressed a kiss to his palm. His eyes flicked to their sleeping son again before settling on his husband's face. His smile grew, and he whispered, "Let's have another."
Remus's brows shot up his forehead, and Sirius's stomach dropped in the short pause his husband took. They'd only briefly discussed having another child once, and back then, Teddy had been so young, and they'd been so tired that it had only ever been a hypothetical conversation. There was every chance, he supposed, that Remus wouldn't want another.
But, before Sirius could find the words to retract his statement, Remus grinned back at him and leaned closer to kiss his lips. The kiss was hot and full of love, passion and affection. One hand stroked Sirius's cheek while the other was still entwined with Sirius's fingers. He pulled back and smiled brightly at Sirius.
"Let's do it," he panted.

Sirius whined as Remus trailed kisses from his throat, over his chest and down his stomach. He thrust his hips down, drilling himself further onto Remus's fingers.
"Remus, please," he whimpered.
His heat had started that morning, and while he'd gotten through most of the day with relative ease, he'd struggled significantly once Remus got home from work. Given that Remus had followed his lead and switched into loose-fitting pyjama bottoms after an hour of uncomfortable restrictions, Sirius was pretty sure that his husband had found the evening equally as testing.
As soon as they'd put Teddy to bed for the night, they'd tumbled into bed themselves, and it hadn't taken long for Remus to reduce Sirius to a slicked-up, whining mess.
Every nerve in Sirius's body was on edge in the best way possible. His breaths caught in his chest, and he trembled at the slightest touch. He groaned loudly as Remus curled his fingers and grazed his prostate. His thighs were wet with slick, and he was far beyond being ready.
"Remus, please. Knot me. Alpha, please," he whined.
Remus finally looked up from where his face had been buried against Sirius's groin and grinned. He reared up on his knees and stroked his hard prick slowly but firmly. He showed way more restraint than Sirius had ever expected of an Alpha, especially when Sirius was in heat. It was one of the things that Sirius loved about him. That cool, calm manner that grounded and balanced Sirius's often erratic moods also lent itself to Remus's outstanding ability to hold on to his self-control long enough to ensure Sirius got precisely what he needed from their couplings.
As Remus pushed inside him and used Sirius's thighs to pull him closer, Sirius cried out. Somewhere in the back of his mind, he was relieved that they'd remembered to charm Teddy's door so he wouldn't be able to hear them. But that thought was quickly driven from his mind as Remus pulled almost all the way out before slamming in hard. Any coherent thought evaporated as Sirius lost himself to pleasure and came hard.
"God, Sirius," Remus's voice broke through the haze, "I'm so close."
He dipped his head and nipped at the sensitive skin over Sirius's scent gland.
Sirius twisted his fingers in the sandy curls on Remus's head and gave a sharp tug as his body continued to tremble through the aftershocks. "Come for me, Love," he panted. "Knot me, please."
Remus moaned loudly, his knot expanding as he groaned, "God, yes, Sirius. Gonna fill you with pups."
"Remus! Remus, yes! So full, Love. Please," Sirius whined as he ground down on Remus's dick.
"Daaaaaaad!!" A frightened wail came suddenly from across the hall.
Remus froze, his knot deflating rapidly, and Sirius growled in frustration beneath him, "Fuck's sake."
Remus let out a frustrated chuckle and dropped a kiss on Sirius's sweat-covered shoulder. "I'll check on him. Wait here."
Sirius rolled his eyes, "Where else would I go?"
He rolled to his side and watched Remus slip into a robe before leaving the room. His body felt weak, and he was still panting heavily. He was burning with need, and knowing he'd been so close to being knotted only made the ache worse. He swallowed gulps of air and strained his hearing to listen to the hushed conversation across the hall. He couldn't make out what Remus was saying, but his voice was the soft, calming tone Sirius recognised as the one he used to soothe him and Teddy after a nightmare.
He sighed heavily and willed himself to move from the bed, his parental instinct overriding his more primal one. His heart pounded, and his legs shook beneath him, but he managed to pull himself together just enough to pull on a pair of shorts and follow Remus into Teddy's room.
"What's up, tyke?" He asked softly as he crouched beside Remus at the side of Teddy's bed.
"Bad dream," Teddy sniffed between sobs. His little shoulders shook, and his round cheeks were red and tearstained. Remus sat, smoothing his short dark curls and shushing him softly.
"It was just a dream, Ted. It wasn't real, I promise," Sirius reassured him.
"Settle back down now," Remus soothed.
Teddy clutched his stuffed dog and shook his head fiercely, "Can't."
Remus sighed, his fingers still moving through Teddy's hair. He turned to look at Sirius and raised an eyebrow. Sirius understood his frown immediately and forced a comforting smile, "Come on then. You can snuggle with us for the night."
The following days passed in much the same way—hours of sexual frustration followed by a rushed bedtime and a few blissful moments of pleasure. But, every time Remus got close to knotting his husband, Teddy would cry out. Either he'd had a bad dream or needed the toilet or a glass of water. One time he woke up in a state because he couldn't find his dog, which had fallen down the side of his bed. After four nights of failed attempts, Sirius was practically resigned to the idea that Teddy might have to be an only child.

By Saturday morning, Sirius was at his wit's end. His nerves were fried, and his brain was addled. Even the usually calm and collected Remus was struggling to keep a lid on his temper and frustration. His more typical alpha behaviours had been creeping out more and more the more wound up he became. Sirius's skin felt like it was covered with ants, and he knew it was making him short and irritable. So much so that he was struggling to enjoy their regular weekend playdate with James, Lily and Harry.
Teddy and Harry were giggling and squealing joyfully as Remus and Lily pushed them higher and higher on the swings. But the usually heartwarming sound set Sirius's teeth on edge. He balled his fists and gritted his teeth as he fidgeted on the bench next to James. His underwear was soaked with slick, and every time he so much as looked at Remus, he could feel his dick hardening. It was a nightmare.
"Alright," James finally spoke up, wrenching Sirius from his thoughts, "What's up?"
Sirius grunted, "What makes you think something's up?"
"Oh, I don't know. It could be the way you've practically growled whenever you've spoken. Or it could be the scowl that's been tattooed on your face all morning. I haven't seen you look this sour since the time in sixth year when you got flu and Moony wouldn't shag you till you were better."
Sirius's scowl deepened, and James choked back a laugh, "Oh Merlin! That's it isn't it. Remus is holding out on you again. What did you do this time?"
"Nothing!" Sirius snapped, briefly catching the attention of a few nearby parents. He cleared his throat and lowered his voice, "It's not like that. It's... We've been trying for another baby."
"Pads! That's amazing news."
Sirius huffed, "It would be if our firstborn wasn't the biggest cock-block I've ever known."
This time James's laugh fully erupted from him. Tears ran down his face, and he gripped his side as he doubled over. He took a few shaky breaths to compose himself. After a few false starts, he held up his hand in apology.
"Honestly. Prongs. The kid has a built-in knot detector, I swear," Sirius said as he threw his hands in the air.
"Well, maybe he just really wants to be an only child," James snickered. His laugh grew again as he took in the way Sirius's eyes widened, and his jaw dropped.
"Pads, I'm joking. I'm no expert, but I'm fairly sure your four-year-old son isn't intentionally cockblocking you. He probably has absolutely no idea what you two are up to. It's the joy of under-fives; I'm afraid. They all go through phases. We had something similar with Harry a couple of months ago. Poor kid was unsettled at night for a week or so, and then all of a sudden, he just went back to normal. And thank Merlin, he did because none of us were functioning by the end of it."
Sirius pouted and shook his head, "That's great and all. But my heat will probably stop before he does. And knowing my luck, he'll reach another sleepless phase when the next one comes around."
James tilted his head. His eyes moved to watch their kids on the swings until he caught Lily's gaze. The smirk on her face suggested that she and Remus were having a similar, but more child-appropriate, conversation. He gave her a subtle nod before turning back to Sirius.
"Look, why don't we have Teddy for a couple of nights? Give you guys the time you need to get everything out of your system."
"Are you sure?" Sirius asked tentatively. He glanced over at Remus and Teddy. His son was kicking his legs and chatting excitedly to Harry so quickly that Sirius had no clue what they were saying. He caught Remus's eye and spotted the subtle nod and pleading look in his eyes.
"I'm sure," James smiled. "I don't think you and Remus being this sexually frustrated is good for anyone."

The moment Sirius and Remus were safely home and had complete privacy, Remus had Sirius pressed against the wall. He devoured Sirius's lips in a hungry kiss, groaning in pleasure as Sirius palmed the bulge of his erection through his trousers.
"This is going to be quick I'm afraid," Remus panted as he tore open Sirius's trousers. "I don't have the patience to tease anymore."
"Don't care," Sirius responded as he dragged Remus's trousers and boxers down over his hips. "Just need you, now. Need your knot."
Remus growled and quickly hoisted Sirius into the air. Sirius wrapped his legs around Remus's hips and tangled his fingers in his hair.
After days of sexual frustration, there was no time for much foreplay, and after a hurried preparation, Remus pushed inside Sirius, eliciting a deep guttural groan from Sirius. Remus pushed slowly until he was completely sheathed within his husband and paused, grazing Sirius's scent gland with his teeth. Encouraged by Sirius's needy whimper and the tightening of his thighs, Remus rocked his hips. He pulled back until just the top of his cock was still inside Sirius and then quickly slammed back in.
Sirius cried out and tightened his fingers in Remus's hair, holding him close and begging to be marked as Remus set a pounding pace. It never took long for Sirius to become putty in Remus's hands, but after such a frustrating heat cycle, he dissolved quicker than ever. In no time at all, he was chanting Remus's name in time with his thrusts.
Remus dug his fingers into the soft, pale flesh of Sirius's thighs as he felt the familiar tightening in the pit of his stomach. He nipped at Sirius's swollen scent gland and purred.
"God, Sirius. You feel so good. You're gonna look so pretty on my knot."
Sirius could only cry out incoherently as he trembled through his orgasm, clinging to Remus as if he were afraid he might float away.
A muffled cry escaped Remus's lips in reply as he bit down hard on Sirius's neck, and his orgasm ripped through him. He heard Sirius gasp as his knot finally caught, and he smiled. Calm began flooding his mind and body for the first time in days as he held Sirius's still trembling form in his arms.
Remus carried Sirirus to the living room on shaking legs and collapsed onto the sofa. Their bodies still joined, they kissed lazily, Remus occasionally lapping soothingly over the bite mark he'd left on Sirius's skin. By the time Remus removed himself, Sirius was snoring softly against his chest, a soft, peaceful smile on his face and a hand resting unconsciously on his stomach. Remus chuckled and lay Sirius under a blanket. He'd need plenty of rest if they were to truly make the most of what remained of his heat.

Sirius stood under the shower, revelling in the constant trickle of warm water over his skin. He sighed happily and smiled as he pressed his palm to his abdomen. His heat was finally starting to burn out after hours of breath-taking lovemaking, and the needful haze was fading, replaced by a calm serenity. He stared down at his flat stomach and ran his fingers over the smooth skin, smiling softly as he imagined a small bump growing there in the near future.
"Do you think we did it?" Remus's warm voice floated through the steam-filled air.
Sirius looked up at him and shrugged lightly, though the smile stayed on his face. "Let's hope so. Otherwise we may be needing the Potter's to babysit some more."
"I'm sure they wouldn't mind," Remus smiled as he padded across the tiled floor.
A shiver raced up Sirius's spine as Remus joined him in the shower and wrapped his arms around Sirius's waist. He kissed Sirius's shoulders and ran his hands over his body, gently stroking his stomach.
The warm water washed over them, and soft tendrils of steam hung in the air as they exchanged gentle caresses and whispers. Sirius relaxed, his head lolling back against Remus's shoulder. A wicked grin twitched on his lips as he pressed further back into Remus's body and guided his lover's hand to his groin. He squeezed Remus's hands around his balls and thrust his arse against Remus's swelling cock.
"Once more, for luck?" Sirius whispered.
"We have to pick Teddy up soon," Remus countered, though his hand began to stroke Sirius's growing erection firmly.
"We best make it quick then, hadn't we?" Sirius purred as he thrust his hips, grinding his arse against Remus before pushing his dick further into Remus's fist. He gasped as Remus's other hand slowly dragged up from his hip, over his stomach and chest, to play with his sensitive nipples, sending waves of pleasure through his body. When Remus scraped his teeth along his scent gland, Sirius knew he was a goner. His body felt liquid under Remus's careful ministrations, and it was only by some miracle of willpower that he was still standing.
"I think I'm going to take my time with you, little omega," Remus purred in Sirius's ear as he nipped at the lobe and dragged his tongue and teeth along the smooth, pale column of Sirius's neck. "I'm going to play with you until you can't take anymore, and then I'll take my time opening you up with my fingers and tongue. And then, when I'm ready, I'll knot you." He gave Sirius's dick a firm squeeze to accentuate his point, and Sirius whined in pleasure.
Sirius's skin prickled along the path Remus's fingers took in, exploring him. His body twitched and trembled as every single nerve fired up in pleasure. He couldn't hold it together much longer. An undignified whimper slipped between his lips. "Remus, please. I can't..."
Remus chuckled and moved his hands to Sirius's hips. He held him gently and whispered soothing words until Sirius's trembling slowed. Once he was sure Sirius could move again, he walked him towards the cold, water-slicked well. He pressed Sirius's palms to the wall and stepped back to give his lover time to catch his breath. His eyes roamed the glistening, wet body before him, and his cock twitched eagerly. If he weren't so intent on tasting Sirius before knotted him, he'd have been pounding into him already. The smooth planes of Sirius's back shone under the droplets of water that clung to his skin, and his muscles twitched as water dribbled down his over-sensitised skin.
Remus licked his lips and fell to his knees. He groaned as he spread Sirius's cheeks and was met with the sight of Sirius's still-loose pink rim, leaking with slick.
"Look at you," Remus purred, ghosting his breath over Sirius's sensitive ring of muscle. "All loose and leaking and ready for me. Good little Omega."
Sirius whimpered and pushed his hips back in search of Remus. With a wry chuckle, the werewolf dove in, licking a stripe along Sirius's crack. Sirius was already falling apart. A string of lewd noises spilt from his lips as Remus lapped at his hole, alternating between soft kitten-licks and delicious scraping of teeth along Sirius's ass cheeks. A minute later, with Sirius's legs trembling beneath him, Remus plunged his tongue inside his lover, groaning in delight as he feasted on Sirius's hole. He curled his tongue, licking Sirius out and opening him up with ferocious intent.
"Remus!" Sirius panted, his hands balled into fists against the wall. "Remus, please!"
In answer, Remus slipped a finger in alongside his tongue, opening Sirius further. Once Sirius was properly stretched and crying out for more, Remus could hold on no longer. With his hands firmly gripping Sirius's hips, he moved to stand behind Sirius and pushed inside, moaning loudly at the delicious hear of Sirius's body. He quickly set a punishing pace, pounding Sirius's prostate with each thrust. Between the intense feeling of being inside his husband and the effect of Sirius's cries of pleasure, Remus knew he wouldn't last long.
"Sirius, God. I'm so close. Touch yourself, Siri. Make yourself come on my knot."
A strangled cry burst from Sirius as he quickly obliged, stroking his swollen neglected cook. Their pleasured moans mixed with the steam in the air as they raced towards their climax. Sirius came first, crying Remus's name as he released and splatted against the tiled walls. The feeling of Remus's knot catching as he came only extended Sirius's orgasm further.
Finally sated and exhausted, Remus cleaned him, knowing this was just a glimpse of the caring, nurturing side of his Alpha that would no doubt come out more often if their rutting had been successful. He sighed happily and closed his eyes, revelling in the comfort of Remus's arms until they were clean, dry and able to collect Teddy.

One year later...
Sirius carried a wriggling Teddy out of the bathroom, trying frantically to dry the boy's unruly curls. He deposited his son on the floor in his room and began wrestling him into pyjamas. Despite his tiredness, Sirius chuckled and enveloped Teddu in a bear hug, covering his face with kisses.
"Just where do you think you're off to in such a hurry?" He asked between laughter and kisses.
"Wan' see baby Hope before she goes sleep," Teddy giggled. "She won't sleep right if she doesn't get goodnight kisses."
Sirius's heart swelled, and he gave his son another tight hug. His fears that Teddy had been deliberately cock-blocking them couldn't have been more irrational. From the minute they'd told Teddy about the pregnancy, the four-year-old had barely let Sirius out of his sight. It had become a recurring joke that he was more protective of Sirius and the baby than Remus was. He'd frequently curled up with his head against Sirius's belly and told the baby how excited he was to meet her, promising to be the best big brother he could be. And from the moment she'd been born, Teddy had kept his promise.
The youngster doted on his baby sister. Sirius often found him showing her his favourite books or toys. Sometimes Teddy would sit and watch Hope with a look of sheer amazement - like he couldn't believe how small and amazing she was.
With a final kiss to the top of Teddy's curls, Sirius let him go. "Go on then. Gently though, Ted. Your dad might be feeding her so don't make her jump."
Teddy scurried down the hall with Sirius hot on his heels before clambering onto Remus and Sirius's bed, scooting alongside Remus as he placed the baby in the cot beside the bed. Teddy peered into the crib and smiled as Hope cooed at him and wriggled at the sight of her big brother. As Teddy leaned over to give Hope her goodnight kiss, Remus gently stroked his back, talking softly to the two children.
"You want to share your bedtime story with hope tonight, Ted?" Remus asked.
As Teddy nodded vigorously, Remus was already pulling their favourite book from the bedside table. Sirius moved gracefully and curled up on one side of the bed as Teddy tucked himself between his dads, his head against Remus's shoulder so he could see the book. Sirius watched over the top of Teddy's head as Remus began reading, the setting sun behind them bathing them all in a warm light. With one hand resting lightly on Hope's belly as it softly rose and fell and the other gently carding through Teddy's hair, Sirius was more content than he'd ever been.
