Title: Mary

Pairing: Dean/Castiel

Rating: K

Prompt: Omega!Dean spending time with his first child. Maybe Dean getting up in the middle of the night to see Cas' interacting with them?

Notes: Unbeta'd.

She was beautiful, completely stunning, and she was Dean's. That thought hit him pretty hard. This adorable green eyed dark haired baby was his. Well, and Cas' but didn't see him spending four hours pushing her out.

She was slightly pale, and blinking blurrily up at Dean, while he and his mate looked on. "Dean," Cas said, choking back his own sob. "Dean, she's so beautiful."

He felt Cas' kiss his head, reaching around him to grasp at the baby's tiny fingers. She looked up at Cas, hand wrapping tightly around his finger.

Dean could feel tears welling up behind his eyes, one slipping down before he could blink it back. Every complaint, ever swollen ankle, every weird ass food craving, and every morning puking up his guts led up to this – this beautiful creature he was holding in his arms.

It was more than worth it.

"We need to put her in her crib," Cas whispered softly, his fingers fluttering softly over her forehead. Dean sighed, begrudgingly accepting it and handing her over after a soft kiss to her forehead.

"Make sure you tuck the blanket on her side so she doesn't roll over!" Dean called after his mate. Cas just turns his head from where he was walking away to give Dean a I – know – this – you – idiot – I – think – I – actually – told – you – that look.

Dean just smiled at him, puckering his lips to blew him a kiss before watching him walk away. Dean sighed as he got up from the chair in their living room, stumbling his way down the hall to Cas and his room.

He was dead tired, hours of nursing and birthing, it was amazing he had the energy to even walk. He landed in the bed with an 'oomph' before everything turned black.

The sound of screaming startled Dean out of his blissful sleep. God damn it. Dean rolled over, intent on bribing his mate with a blowjob if he would just go check on Mary, to find an empty but warm side of the bed.

Ah hell, he needed to check on her.

Groaning and mentally damning Cas, he got up, disgusting himself by finding him still in yesterday's clothing. He groaned again, stretching out and walking blurrily down the hall. He stopped at Mary's door, pushing it open, just to stop cold.

His mate was shifting his weight from leg to leg, shuffling awkwardly around in a small square holding their daughter. He was humming under his breath, patting her back while she fisted a hand in his shirt. Dean leaned against the crown molding of the doorway, arms folding across his chest.

"So watcha singing?" Dean whispered softly, smiling as his mate turned around sharply.

"You startled me," Cas whispered, had coming up to rest behind their daughter's head. Cas walked slowly over to Mary's crib, laying her down. He leaned down to kiss her forehead before walking over to Dean, wrapping his arms around Dean's waist.

"So what were you singing?" Dean repeated, humming in pleasure as Cas kissed his neck.

"Oh, uh," Cas pulled back, face crimson even in the dark. "It was 'Hey, Jude'." He finished.

Dean's hands tightened from where they were wrapped around his midsection, breath catching in his throat.

"I, well, I remember you said your mom used to sing it to you when you were little and I thought…" Cas trailed off, taking in the tear strained face of his mate. "Dean, are you…"

Dean chuckled, voice slightly hysterical. "You, you remembered that?"

Cas nodded slowly, one hand coming up to wipe away a tear from Dean's face.

Dean twisted a hand in the front of Cas' shirt, pulling him in. Their mouth slotted together, tongues tangling together. They broke apart a moment later, foreheads pressed against each other breathing in each other.

"You're a great father," Dean whispered hoarsely, smiling softly.

"And you," Cas kissed his nose, "Are a great mother."

All Cas got in reply was a scoff and a soft kiss.
