Castiel scraped the bottom of the glass jar with a small plastic spoon, gathering up the last vestiges of sweet potato goo. When he looked up again it was to see Beckett waiting, mouth wide open like a baby bird, as was her habit. While there was the usual array of annoying habits, like the six painful months before she'd slept through the night, Beckett maintained a healthy appetite. At eight months they'd converted her entirely to baby food and blood. Even when Dean had been breastfeeding her they'd given her a bottle of the stuff a day, for nutrients sake. Hybrids needed it, even as infants, particularly with their accelerated growth and development rates. More than adults when you took into account the size ratio. They'd upped her intake to two or three bottles, however much she needed. They did give her regular milk too, sometimes juice, but blood was still her favorite. Preferably B+. They didn't know why.

As the Alpha maneuvered the spoon into his daughter's mouth their microwave went off, and Dean pulled out a mug. He stuck his finger into its contents to check the temperature, pushing the door closed. Castiel rose to discard the jar and set the spoon by the sink as Dean started to pour warmed blood into a Sippy cup.

"She eat everything?"

"Yes. Two jars. We should switch to blood before she fills herself up entirely."

Dean grunted, screwing on the lid on tight. He plunked the Sippy cup on Beckett's tray, which she immediately snatched up. The Alpha went to rotate her highchair as Dean finished making their own dinner, as was their routine. While she could be a fussy child she was well behaved most of the time, and Castiel had been relieved to find that particular rumor was right. Things were indeed different when the child was your own.

Despite his initial delight at finding out Dean was pregnant, there was more than one occasion where he felt remorse over not explaining in detail the need for birth control. Namely when his mate was in pain, which turned out to be more often than he liked. The morning sickness was bad enough, which he'd insisted on being present for once he knew. He hated seeing his proud mate reduced to a pale faced, groaning mess. Dean had kicked him out routinely, but after a week had given up.

The horny stage had been fun for both of them, even though it did occur right after Castiel had stopped feeding from him. From the time he found out his mate was with child until after he'd recovered from birth the vampire hadn't let his fangs get near Dean, though the human had grumbled. Castiel hadn't exactly enjoyed reverting back to the donated stuff, but he didn't like the idea of feeding from another human directly and he wasn't about to take nutrients from Dean when his mate needed all he could get.

This became more obvious the bigger Dean got. Morning sickness didn't seem so bad once it was over, and compared to other symptoms. Backaches, swollen ankles that also ached, Braxton Hicks contractions, going on walks every night because he couldn't find a comfortable position to sleep in...Castiel had hated it. He'd helped where he could, but in truth there was little he could do besides remain at Dean's side. What's more, for reasons unknown to the Alpha Dean was convinced that he was as far from sexy and desirable as could be imagined. This was hardly true. Yes the human was something of a hot mess, as he knew himself to be, but Omegas were constantly failing to understand the appeal it had for an Alpha, seeing their mate swelling with their child. It had been intoxicating, watching his belly grow, hearing a little heartbeat growing louder and stronger with passing months, knowing that this was their child, his child...Dean still didn't believe him but the Alpha didn't care. Up until a mere week before Beckett had been born they'd maintained a very healthy sex life.

That had been Castiel's final regret. They'd gotten Dean to the hospital in plenty of time, but their daughter had decided to take her sweet time. The epidural had worn off when the time came to push. Dean had not been happy. Castiel had felt two bones in his hand snap as his mate gripped it, swearing through gritted teeth. Things had started to change when he'd heard that first cry. Whatever doubts he might have had were thoroughly snuffed when he'd first held her in his arms. She was tiny and pink and bald but damn it if she wasn't the most beautiful creature he'd ever beheld. His world had completely rearranged itself as he watched Dean hold their child for the first time, watched pure maternal love eclipse his face. He hadn't realized just how badly his mate had wanted a child until that moment.

Since then things had hardly been gumdrops and rainbows, but he still wouldn't have it any other way. Castiel decided he liked this new, domestic aspect of his life. It took some balancing, and he went out of his way to safeguard any influence the less pleasant side of his work might have on his daughter, but they managed.

Tonight's routine went as it often did. After dinner Castiel cleaned up the kitchen, then they spent some time with her in the living room. The Omega had been trying to get her to walk, with varying degrees of success, but he insisted Beckett had managed to go a whole three feet on her own. Castiel soon discovered she had, but only because Dean plopped her down by the couch and held her favorite toy away from her. Beckett wasted no time in dragging herself to her feet and toddling a full yard so she could brace a hand on his chest, shrieking in protest as she reached for the toy. Dean let her have it, beaming in pride. Castiel tried to be disapproving of the method, but he couldn't help it. He was proud too. Their baby girl was walking.

Eventually they did have to wined her down, get her into a bath and get her to bed. This took longer than Castiel would have liked, especially considering what he had in mind for that night. But eventually they were able to retreat to their own rooms for showers and bed. Not sleep, just bed.

As soon as Castiel stepped out of the bathroom, hair still damp, a hand tangled in his night shirt and yanked him into an eager kiss. He returned it, of course, and then some. The Alpha yanked Dean's t-shirt over his head, then shoved him bodily back onto the mattress so he could drag off sweatpants and underwear, tossing them aside. He jerked off his own clothes before climbing onto the bed with his mate, earning a surprised grunt from the Omega as he lifted him bodily off the sheets, moving him so his head dropped onto the pillows.

"Fuck me, Cas, fuck me good," Dean growled. "Need you..."

Castiel kissed him one last time, waiting until the tiniest of whimpers tricked through his mate's lips before pulling away. He flipped Dean onto his stomach, snagging the cuffs from the bedside table where he'd left them. Police issue but specially modified, to insure they wouldn't cause his mate undue pain. He snapped one cuff over one of Dean's wrists and slipped the short connecting chain through the headboard bars before the human even noticed what was happening. By the time Castiel had both wrists secured, it was too late.

"Damn it this wasn't what I- son of a bitch!"

"Shh," the Alpha scolded, lips curling up in a smile as he pressed his lips to Dean's ear. "Don't wake the baby, Dean."

Earlier today the vampire had decided to have some fun. Sex and orgasms always made Dean's blood sweeter, courtesy of hormones and chemical releases. The more drawn out and intense the experience, the better the blood. This morning, after blowing him and fingering him to an orgasm, Castiel had slid a sizeable toy inside his mate. One that would nudge his prostate no matter what position he was in, one that could be made to vibrate at three different levels of intensity via remote. At random intervals that day Castiel had turned it on, but only to low or medium levels. In the same moment he had brought one hand down on his mate's backside, he'd flipped it all the way up to high, hence the yelp from his mate.

Despite the red in his face and his vocal protests, Dean was already hard and very wet. Lightly kissing the back of his neck, Castiel slowly drew out the toy, taking his time, enjoying the way it made the Omega writhe on the bed. He turned off the toy once it was out, tossing it aside. Shifting his position to kneel at Dean's side, the Alpha bent down to nip his ear, catching the shell lightly between his teeth, enjoying the shiver than ran down the Omega's spine.

"Present," Castiel ordered, brushing fingers through his hair.

The Omega tugged at his bonds, but then reluctantly dragged himself to his knees, keeping his head and shoulders down, back arching in a smooth curve as he got his ass as high as possible while spreading his thighs. Castiel sat back for a moment, appreciating the view. Oh gods Dean was a thing of beauty, and he was his. Better still, from this angle Castiel could see the slick starting to trickle down one thigh and the white marks on his stomach. Battle scars acquired when the Omega had born their child, made a new life. Dean didn't like them, but his mate loved them.

Settling a hand on one rounded buttock, the Alpha moved to kneel behind his mate. Knowing full well moving slow drove his Omega mad, he made sure to take his time about it. Though maintaining his snail-like pace when moving his grip to Dean's hips and pushing slowly inside him was difficult. His fangs had dropped from his mouth by the time he was done, ragged pants in his throat. Despite the fact Dean kept struggling, trying to push back onto his cock, he'd barely resisted the temptation to just do as his mate wished and fuck his brains out. No doubt his control would break soon enough, but he wanted to make this last.

"Son of a bitch would it kill you to move fucking faster?" The moan of protest was muffled by a pillow, forcing a wry smile onto Castiel's lips.

"No. It won't kill you either."

"Fuck you."

"You are."

A noise that was half groan half moan drifted up from the pillow, followed by a sharp whimper when the Alpha wrapped fingers around his throbbing cock.

"You can cum all you want, Dean. But I won't let you go until I do."

"Damn it Cas, how the hell am I supposed to do anything if you don't fucking move?"

Rather than reply, Castiel went to work. While one hand remained braced on Dean's hip, knowing the Omega would take matters into his own hands if he didn't, the other went to work on his mate's cock. This was done faster, using the Omega's own slick for lubricant as he rubbed and twisted and stroked, brushing the slit with his thumb, the brisk motions a high contrast to his slow thrusts.

"What are you- oh gods don't- okay, I get it, you don't have to...aaaahhhhhh...shit!"

The final curse was bit out moments before Dean hit his climax. Castiel shuttered, but maintained his pace. It was difficult, especially when the Omega clinched down on him, the cock in his hand spurting cum. Despite this, he didn't stop. He maintained the slow thrusts, nudging the Omega's prostate almost every time, hand still working his dick.

"Cas." It was a drawn out utterance that could only be called a whimper. "I-I get it, I...oh gods..."

A pleased smile curled on Castiel's face. The most his mate had cum in one round had been twice. Sure they'd done more in one day but after that second climax he was oversensitive and drained and needed recuperation time before another round. Even one left him out of breath and sensitive, two was his limit.

"Would you like to cum again?" He tried to sound casual, though he wasn't sure how successful he was. Being inside Dean when he climaxed was incredible, and if it wasn't for his slow pace it would have sent him over the edge. As things stood he was hoping to get a second, maybe third climax out of his Omega.

"Up yours," was the choked reply.

Castiel cracked a smile, bending down to lightly traced the tip of his fangs over the base of the Omega's neck. "I wasn't aware you had interest in switching roles."

There followed a string of croaked and whimpered curses, none had much force behind them. Not until Dean started to get close to the edge, anyway.

"Damn it Cas would you hurry up? Son of a bitch- fuck."

The Alpha gritted his teeth as Dean went over the edge, clinching down. His mate tried to push back against him, fingers twitching in the cuffs, one leg reaching back to try and hook around the vampire. Castiel waited, breath coming in ragged pants as he fought to stay away from the edge, eyes fluttering closed as he savored the sensation of having his mate cum on his cock.

Only after the orgasm had passed did Castiel pull out, not missing the tiny, relieved whimper this earned from his mate. It was followed by a yelp when he bit into Dean's leg, the one that had been trying to keep him from moving. He shoved it back into place, propping his ass back up into the air and licking the trickle of blood from his thigh.

"I didn't tell you to change position, Dean," he chided lightly.

"Uncle," was the groaned reply. "I'm calling uncle."

Castiel didn't hesitate, delighting in the loud keening whimper as he pushed back inside his mate. Uncle wouldn't stop him, neither would the actual word 'stop'. They'd agreed. Only one word would get the vampire to quit instantly and without complaint, but until Dean gave it or they were done he would keep going.

"Cas, Cas please..."

The Alpha was sorely tempted to sink his fangs into Dean's neck there and then, orgasm or no. He was so hard it hurt, the only reason he hadn't cum yet was because he'd been fighting it. At the sound of his mate's whimpered pleas he let go. He would have let his pace go to frenzy, but by this point Dean would have to be hypersensitive. It would hurt him. Castiel enjoyed tormenting his mate, but not causing him true pain.

His mate buried his face in the pillow, muffling an outright scream when he toppled over the edge for a third time. This time Castiel fell with him. His vision went white, his limbs almost giving way beneath him. Dean had gone to a boneless heap below him, body trembling as the Alpha slowly crumpled on top of him. Only when his vision resettled did Castiel begin to feed, a weak whimper the only sign Dean was even still conscious.

Oh gods he should push Dean more often. Well, more than he did now. This was the first time since Beckett's birth they'd played, really played. This was the milder of the things his mate enjoyed, but it made his blood incredible all the same. The more intense an orgasm, or the more orgasms he had, the sweeter his blood. The Alpha had once put him over his knee for a spanking session that lasted so long he just had to thrust a few fingers inside his mate to make him cum. Of course vanilla sex was still enjoyable, and Castiel never missed an opportunity to make love to his emotionally weathered mate, but every now and then he would take his time and make Dean scream for his orgasm.

Slowly, as Castiel drew away from his mate's throat, licking the wound, Dean began to stir. His eyes flickered open weakly as Castiel pulled out of him, undoing the cuffs. The Omega dragged his arms down, groaning softly. The vampire stroked his cheek, murmuring a gentle inquiry.

A very weak, incoherent warble came through barely moving lips. The vampire wasn't even sure if it was meant to be a word, but it sounded pleasant, happy.

Satisfied his mate was just drained, in more ways than one, Castiel set about cleaning them both up. He put away the toys, discarded the towels he'd laid down over their bed, and ran a warm cloth over his mate's skin. He made sure their clothes were in grabbing distance before rejoining Dean in the bed, tucking the Omega in and settling down at his side. He knew his mate was truly out of it when he turned to nestle against his chest, turning his nose into the vampire's neck.

Castiel cracked a smile, stroking Dean's hair and kissing his forehead. "Rest, Dean."

"I'm gonna hate you in the morning," was the mumbled reply.

He didn't bother correcting him or arguing. Instead the vampire closed his eyes, content. It would be even more difficult with a child around, but he'd like to try doing this more often. He loved reducing Dean to such an out-of-character state. Maybe next week he could convince Dean to submit to a round of corporal punishment in the lacy panties he loved so much.
