Summary: Sometimes Sam and Dean need a break from their train-wreck lives. When that happens, they stop being brothers. Dean becomes Daddy and Sam becomes Sammy, his baby boy, just for a few hours.
Note: Not set in any particular season, so hopefully can be imagined at any point in the series/pre-series/post-series that you want. Thanks to kinkajou on Twitter for encouragement to write this, my first attempt at actual infantilism.

It's not like the could do this often. With the constant danger and hunting and life never cutting them a fucking break, Sam and Dean had to be at their best all the time. Never let their guards down. Never show weakness. Never let the stress get to them.
There was a lull now, though, and Dean knew that if they didn't take a couple of hours to decompress, one of them was going to blow up. Possibly both of them, and that always had catastrophic consequences.
So when Sam stood in the bathroom door, hesitant, clutching his blankie in one hand, Dean felt weeks of tension sliding off. He smiled and held out his hands.
“Does Sammy need his Daddy?”
Sam - no, he was Sammy now - seemed to collapse forwards as though he was a puppet with his strings cut. Dean caught him and lowered him to the ground, making sure to support his weight. He let out a little chuckle.
“You know you can't walk yet Sammy. Come on, I think my baby boy's in need of a nap.”
Dean carefully walked out into their motel suite, Sammy crawling next to him. His movements were a little awkward, as they always were at first, but soon he'd be fine. When they got to the love-seat Dean crouched, wrapped his arms around Sammy's middle, and heaved. He couldn't easily carry his baby boy around any more, which always made him a little nostalgic, but he was strong enough to find ways to work around that. Once he'd gotten Sammy situated, he gently stripped him of his clothes.
Sammy was already smiling again, blankie still firmly in his grasp. That made it a little difficult to remove his shirts, but Dean was used to it by now. So instead of fighting, he removed the sleeves from Sammy's free hand, then tickled his stomach. Squealing in delight, Sammy released his blankie as he waved his arms around. Dean quickly moved the blankie to Sammy's other hand and finished undressing him.
Once Sammy was fully naked, Dean went over to the special duffel that Sam had brought in earlier. In it were the supplies for when they did this, the toys and the bottles and the clothes. Going through them, Dean pulled out a diaper and a soft, pale green onesie with dinosaurs on it. Mentally he sent out a brief thanks to the fashion deities for making onesies fashionable, or at least acceptable - it was so much easier now that they could get them in Sammy's size at frickin' Wal-Mart instead of having to special order them.
Getting Sammy redressed wasn't difficult, if he could ignore the lack of room. Sammy had always been a pretty easy-going baby - it was when he'd been walking and talking and really thinking for himself that the trouble had started. Now, though, when they played like this, he could go back to just being a bundle of instincts. He could let Dean make the decisions, safe in the knowledge that his Daddy wouldn't let anything bad happen to him.
Safely diapered and dressed in his pyjamas, Sammy rolled over onto his side and yawned. Dean smiled and went back to the bag. After a bit of thinking, he pulled out the fluffy duck and swapped it for Sammy's blankie, which he draped over Sammy. Tucked in, cuddling his Duckie, Sammy looked the very picture of innocence. Dean smiled and pressed a kiss to his forehead.
“Does Sammy want his binkie?” Sammy pouted, and Dean chuckled. “Not yet then. How about bed-time bottle?” The smile was back.
In Sam and Dean's relationship, Sam was generally the one in control, the 'top' in the bedroom, although Dean challenged him at every turn. It was different with Sammy though. With Sammy Dean didn't need to fight for control, to worry about where Sam was or what he was doing, or about the general state of the world. Here it was just them, and the world could go to hell for all he cared.
Basking in Sammy's look of contentment, Dean knelt next to him and undid his jeans, pushing them and his underwear down. His cock wasn't yet hard - it wouldn't do to have inappropriate erections around his baby boy - but he knew that would change pretty quickly. Sammy opened his mouth and Dean gently pressed his dick inside, letting Sammy suckle on it.
Leaning forward, Dean braced himself with his left arm on the back of the love-seat and used his right hand to stroke his hardening length. In this position Sammy could only really suckle on the head, but that was fine - the rhythmic suction was pleasant for Dean and soothing for Sammy, and he could jerk himself off easily.
In the early days it had been hard to keep from thrusting, but now Dean was used to it and had better control over his own body. His hips stayed motionless, all the friction coming from moving his hand, stroking and squeezing in turn. Sammy looked perfectly content, eyes drifting shut as he kept sucking, chasing the release Dean could never keep from him.
“Good boy, Sammy,” Dean whispered, unable to hold his silence. “That's my baby. Keep sucking, it's coming, being such a good baby boy for Daddy. Gonna give you a nice big drink, then you can have a nice long nap. Damn baby, such a good mouth...” He trailed off as he felt himself getting closer, breath coming in pants. With a grunt, his hips twitched and he let go, spurting straight into Sammy's mouth.
As always, Sammy let out a pleased noise and kept suckling, swallowing down everything Dean had to give. It was one of Dean's favourite sights, his baby boy looking so happy as he closed his eyes and finished his 'bottle'. When he was done, Dean let him keep sucking for a few minutes, as though chasing more of his treat. It was edging close to the side of 'too much' on his sensitive flesh, but it was worth it to see Sammy slowly drift off to sleep.
Eventually he slipped out of Sammy's mouth, and turned back to the rest of the room. He'd have about half an hour while Sammy napped, and he needed to make the most of it. First up he got himself a meal, knowing that he'd need his strength as the day went on. That taken care of, he prepared a couple of proper bottles for when Sammy woke later - one filled with juice, one with plain milk, so that Sammy would have a choice. He pulled the coffee table away from the love-seat and put several pillows and the blankets from the bed on the floor, just in case Sammy fell off when he woke up. At least he'd have a soft landing.
Finally, he lined up several toys on the coffee table, still not sure what he wanted to use. He'd wait and see what sort of mood Sammy was in after his nap.
With the room set up to his liking, Dean quickly went into the bathroom and gave himself a quick wash. He was disappointed now that they'd gotten a room without a bath, so he couldn't bathe Sammy properly, but hopefully that wouldn't be too much of an issue.
He was dressing himself again when he heard soft noises coming from Sammy. Dean quickly went over and knelt next to his baby boy, waiting as Sammy woke up properly. As soon as Sammy's eyes focussed on Dean he was smiling again, and Dean leaned in to brush another kiss onto his forehead.
“Did Sammy have a nice nap?” He asked. Sammy kept smiling. “That's good. How about we have a nice cuddle for a bit, then we can play before dinner?”
Sammy reached out for him and made a babbling sort of noise. Dean laughed and carefully manoeuvred Sammy off of the love-seat and onto his lap. They curled up happily and Dean turned on the TV, switching to some kids' cartoons. He kept running his hand through Sammy's hair, the both of them revelling in the closeness as Sammy woke up.
After a couple of shows, Sammy started wiggling and chewing on Duckie's beak. Dean grinned and shifted so that Sammy was on his back on top of the blanket nest.
“Baby boy's awake now, isn't he?” Dean teased. Sammy waved a fist at him happily. “Time to play then. Does Sammy want his binkie first?”
Sammy made a happy noise, so Dean reached over to the coffee table and picked up the special binkie he'd ordered off the internet - the one shaped like a small penis. It was enough of a mouthful to keep Sammy happily sucking, but it wouldn't hurt his jaw or go too far back in his mouth. He held it out, and Sammy opened his mouth in easy acceptance. Once he had a good grip on it, Sammy started absently sucking and chewing on it.
Dean watched him for a moment, then opened up the onesie. The zip down the front was a blessing for times like this. It went down far enough that with a little wriggling, Sammy was still technically wearing it, but Dean could get to his diaper easily. He undid it and peeled it back, quickly changing it for a fresh one after a glance. Sammy wasn't fussed, he was happily cuddling Duckie and sucking on his binkie.
The fresh diaper wasn't done up yet. Dean squirted some lotion onto his hand and started to gently brush against Sammy's genitals, more a question than a demand. Sammy just made another happy noise, and Dean smiled. He made sure that his fingers were nice and wet, before pressing one into Sammy's hole.
Sammy seemed to sigh in contentment, and Dean gently moved his finger back and forth. He'd never hurt his baby boy, this was all for Sammy's benefit, so he used as much oil and preparation as he needed. It didn't take long for Sammy to be relaxed around one finger, and he barely wriggled as Dean switched to two.
Glancing up, Dean let out a chuckle. Sammy was still sucking on his binkie, still cuddling Duckie, and still watching the cartoons, all while Dean had two fingers in him. It didn't seem to make a difference to his baby boy, like this was completely normal. Which, for them, it was.
After several minutes, Dean added a third finger, then a fourth. Sammy was moving a little now, hips hitching in time with Dean's movements and cock standing proud, but other than the flush on his cheeks his upper half seemed almost unaffected. Dean knew, though, that they were about to get to the part of the game that Sammy really liked.
He took a moment to decide which toy to use. He didn't want anything too large, but something to have a little fun with. Eventually Dean decided on a medium-sized vibrating plug. He slipped it into Sammy, who was well-stretched enough that it didn't cause any discomfort. Dean turned it on to the lowest setting, so that it would be a pleasant hum against his prostate, then carefully did up the diaper. He had to be careful when he shifted Sammy's cock to fit back in the diaper, but it was worth it.
With the onesie done up again, Sammy looked perfectly innocent as he lay on the blanket and cuddled Duckie. Dean grinned down at his baby boy, then moved a few feet away and clapped his hands.
“Come on Sammy,” he beckoned. “Come to Daddy!”
With a wriggle, Sammy rolled over onto his tummy. After a few moments he managed to get to his hands and knees, shuffling forwards a little before collapsing onto his side. He was properly flushed now, eyes distant, and Dean was so proud of his baby boy trying to crawl to him.
“That's it baby boy, you can do it!”
Sammy struggled back up, and this time crawled a few feet before the friction was too much and he fell down again. He was panting around his binkie, hips moving on their own as he sought more sensations. Dean took pity on him and helped him up again, before taking two steps back, hitting the bed. He sat down on the edge and patted his knee.
“You're almost there baby. Come on, once you get here you can have your reward.”
Challenge laid down, Sammy grunted as he wiggled forwards, brain practically wiped clean. He finally made it, head-butting Dean's thigh, which made Dean laugh.
“You did it Sammy! Well done, such a good baby for your Daddy.”
With that, Dean undressed Sammy again, this time all the way. He helped Sammy crawl up onto the bed, then took off his own clothes and settled in to sit against the headboard. He pulled Sammy onto his lap and removed the plug. Sammy whimpered in relief where he was collapsed against Dean, sucking on his nipple. Dean let him for a few minutes, palming himself at the same time, then shifted Sammy to straddle him properly.
Sammy was still dripping oil from where it had been kept inside by the plug, so Dean wasted no time in pushing in, and pulling Sammy down. Once Sammy was seated on his hips, pressed against him and mouthing happily at his shoulders, Dean moved his hips as much as he could. This in turn rubbed Sammy against their stomachs, and he knew from past experience that this wouldn't last long.
True to form, Sammy was soon gasping as he came in hot splashes between them. The clenching set Dean off, and he kissed Sammy's neck as he filled his baby boy.
They sat together, panting, for several minutes before Sam pulled back. It was Sam again, though he did look a lot more at ease than he had before their little time out.
“Thanks Dean,” he muttered before sliding back, extricating himself from the bed. Dean grunted and curled up on his side, ready for a nap of his own. There was silence for a few minutes, in which Dean figured Sam was heading for the bathroom to get cleaned up.
“Hey, Dean?”
Dean lifted his head and shot Sam a questioning look. Sam was fiddling with his own hands, looking a little embarrassed.
“D'you think... maybe next time... could we find somewhere with a rocking chair?”
Dean considered the implications for all of two seconds.
“Whatever my Sammy wants,” he nodded.
“And a bath tub?”
“Of course.”
Sam smiled and turned into the bathroom, leaving Dean to think. Next time, he'd find them an apartment to stay in - somewhere nice where they could play for a weekend, with all the toys and furnishings Sammy wanted.
That's what good Daddies did, after all. They took care of their Baby Boys.
