Work Text:

Dean’s back was aching. He knew he was doing too much, but the need to do something was making him unsettled. He shifted his weight from one foot to the other, resting a hand on the curve of his belly. It felt heavier than usual today — maybe it was the weather, or maybe he was just stubborn. Probably both.

The room still smelled like fresh paint and wood. The crib sat half-assembled in the center, pieces of the side rail leaning against the wall where Dean had left them when he realized he couldn't crouch down without groaning like a senior citizen. He stood there, frowning at the instruction manual that lay open on the floor like it had personally offended him.

He rubbed at the small of his back, one hand gripping the top of the dresser he’d pushed against the wall an hour ago… Well, half-pushed, half-shoved. It had taken longer than it should’ve, and he'd had to sit down halfway through and breathe through a cramp that wrapped around his side like a belt.

There were clothes already folded in the drawers. Soft onesies, tiny socks, a couple of little hats that had made him tear up when they arrived in the mail. Some had tags still on them. Some had been gifts. A few, Dean had picked out himself, standing awkwardly in the middle of the baby aisle at Walmart like he was trespassing in someone else’s life.

He walked slowly over to the rocking chair in the corner. It was the only piece of furniture in the room that was completely assembled so far. He sank into it with a grateful sigh. The cushions eased the tension in his back for a moment. He let his hands rest on his stomach, feeling a nudge from inside.

“Alright, alright,” he murmured, cracking a small smile. “You’ve made your point. Dad’s gotta sit down more.”

The room was quiet. Sunlight filtered through the white curtains, casting soft shadows on the pale green walls. It wasn’t perfect yet; the mobile still needed hanging, the shelves needed anchors, and there were books and toys still in boxes, but it was becoming something. Becoming theirs .

Dean let his eyes drift shut for a moment. He felt tired in that deep, bone-heavy way he hadn’t known before the pregnancy. But even through the exhaustion, there was a thread of calm starting to stitch its way through him. He rubbed his hand over his swollen belly, smiling at the small kick he felt, as he rocked in the chair, slow and steady, the creak of the wood a quiet rhythm in the stillness of the room.

“You awake in there, troublemaker?” he murmured, thumb brushing absently across the curve of his stomach. Another little nudge answered him — not strong, but definite. Dean huffed out a quiet laugh, more breath than sound. “Guess so.”

The rocking chair creaked again as he leaned back, letting his head fall against the cushion. He stared at the ceiling for a long moment, then turned his head slightly to look around the room. The soft green walls, the stack of picture books waiting to be shelved, the half-built crib. It still felt surreal. Like it wasn’t really his life, like he’d stumbled into someone else’s calm domesticity by mistake.

But the weight of the baby said otherwise. The ache in his back. The stretch of his skin. The quiet beat of anticipation that had taken root in his chest and wouldn’t let go. 

He exhaled slowly and closed his eyes again, one hand still resting protectively over his belly. “We’re gonna get there,” he said softly, not sure if he was talking to the baby or to himself. “Even if I’ve gotta build this damn crib one piece at a time.”

A distant sound of a door opening and closing reached his ears; faint, familiar. He didn’t open his eyes. Just smiled and let the warmth of it sink in.

At least he wasn’t doing this alone.

“Dean?” The familiar voice of his Alpha called out, and Dean smiled as he heard the sound of the stairs creaking as Cas made his way up.

“In here,” Dean called back, voice low but carrying, and a moment later, Cas appeared in the doorway, his brow furrowed until his eyes landed on Dean in the rocking chair.

Cas’s whole posture softened. “You’re sitting down,” he said, like it was a small miracle.

Dean snorted. “Don’t get used to it. Only sat down ‘cause the kids started kicking and my spine’s about to mutiny.”

Cas crossed the room in a few steps, crouching down beside the chair, one hand coming to rest gently on Dean’s knee. “You’ve been on your feet too long again.”

Dean rolled his eyes but didn’t argue. He shifted slightly, guiding Cas’s hand to his belly. “Here. They’re practicing karate or something.”

Cas’s hand was warm and steady against Dean’s stomach. For a few seconds there was only stillness, and then…there it was. A small, unmistakable kick. Cas’s eyes widened just a little, and his lips parted like he was about to say something but couldn’t quite find the words.

Dean watched him quietly, his chest tightening in a way that had nothing to do with hormones and everything to do with the man in front of him.

“They’ve been more active lately,” Dean murmured. “Especially in the afternoons. Think they know when you’re close.”

“I’ll try to be home earlier,” he said, fingers brushing lightly across Dean’s shirt. “I’ll speak to Cain,”

“You already do enough, Cas. Hell, you’re the one who made dinner last night. I’m the one who’s supposed to be doing this, and I couldn’t even finish the damn crib.” Dean stated as Cas ran his hands over Dean’s stomach again.

“You’re growing two whole people,” Cas said simply, like it was the most obvious and miraculous thing in the world. “You don’t have to do everything yourself, Dean.”

Dean looked away for a moment, blinking hard. He hated how easily those words went straight to his gut. He’d spent so long being the one who held everything up, kept it moving, took care of the hard things. Letting someone else carry the weight — even part of it — was still new.

But with Cas, it didn’t feel like weakness. It felt like safety.

Cas pressed a kiss to his belly, then another to Dean’s knee, before standing and offering a hand. “Come lie down for a bit. I’ll finish the crib.”

Dean hesitated. “You sure? It’s kinda a two-person—”

“I’ll figure it out,” Cas said with a soft smile. “And if I don’t, I’ll call Sam to help me. You need to rest.”

Dean let himself be pulled to his feet with a small grunt, leaning into Cas for a moment longer than necessary. Cas's arms circled around him, grounding and solid.

“Alright,” Dean said finally, eyes fluttering shut against Cas’s shoulder. “But if you lose one of the screws, I get to say ‘I told you so.’”

Cas chuckled. “Deal.”

Placing Jack into the crib, Dean hummed softly, his hand lingering on the soft curve of the baby’s back as he settled into the mattress. Jack let out a tiny sigh, eyes fluttering but not waking. Dean smiled to himself and reached up to turn on the mobile, the gentle lullaby beginning to chime as soft fabric stars turned slowly overhead.

He stayed for a moment, watching the rise and fall of Jack’s chest, the small fist curled up beside his face. The room was dim, just the warm glow of the nightlight casting golden shadows across the nursery walls. Dean adjusted the blanket, then straightened with a soft groan — his back still wasn’t what it used to be.

He turned to glance across the room.

Claire was already asleep in her cot. Her face was peaceful, her soft blonde hair mussed from sleep, lashes dark against her cheeks.

Dean’s chest ached with quiet, overwhelming love.

He walked over slowly and adjusted the blanket around Claire too, brushing a strand of hair back from her face. She didn’t stir.

For a moment, Dean just stood between their beds, surrounded by the soft sounds of breathing and the faint melody of the mobile. This right here was the part no one really talked about. The quiet. The weight of it. The stillness that wasn’t empty, but full of something too big to name.

He exhaled slowly and stepped back, eyes sweeping over the room: Jack in the crib, Claire in her cot, books on the shelf, soft toys lined up in a lazy row, and the rocking chair still in the corner,  the same one he’d sat in all those months ago when he couldn’t imagine how it would all come together.

It had.

A soft rustle behind him made him turn. Cas stood in the doorway, barefoot and rumpled from sleep, his eyes gentle.

Cas’s expression shifted instantly, that quiet alertness he always carried when it came to the kids settling into his features. “Should we take his temperature?”

Dean shook his head, leaning slightly into Cas as they stepped out of the nursery, gently closing the door behind them. “Nah, not yet. He’s not fussy, just… warm. I’ll keep an eye on him. Might be nothing.”

Cas nodded but didn’t look entirely convinced. He reached up and touched Dean’s arm, thumb brushing the inside of his wrist. “You always know before I do.”

Dean smirked. “Parental instinct. Or maybe it’s just that I’ve been spit-up on three times today and my shirt has seen things.”

They padded down the hall toward their bedroom, voices low and movements quiet, like the house itself had learned to breathe softer at night. Dean sank onto the edge of the bed with a soft sigh, rolling his shoulders out. “God, I feel eighty. My back’s never been the same since that damn epidural.”

Cas sat beside him, then shifted so he could start rubbing Dean’s lower back without needing to be asked.

Dean exhaled slowly. “You’re gonna spoil me.”

“That’s the plan,” Cas said, gentle and focused. His fingers found a knot just above Dean’s hip and worked it loose with slow pressure.

They sat like that for a while, the hum of the baby monitor soft on the nightstand, the warmth of Cas’s hands grounding Dean like a touchstone. The chaos of the day had faded into a quiet rhythm, like waves pulling back after the tide.

“Thanks,” Dean murmured finally. “For… all of it.”

Cas leaned forward, resting his chin on Dean’s shoulder. “There’s nothing I’d rather be doing.”

Dean let his head tip to the side, resting it lightly against Cas’s. “Even the diapers?”

“Even the diapers.”

Dean chuckled, low and tired. “Man, we really made a life, didn’t we?”

Cas’s voice was soft against his skin. “Yes. And I wouldn’t change a thing.”
