"Saaaaam." Dean drew out, whining at the loss of warmth from around his waist.

For the past few weeks, once they realized after the nightmare incident that sleeping alone just wasn't the same, cuddling at night had become a regular occurrence. The brothers would get back from a hunt, eat, shower, and jump straight into bed, where they'd wrap themselves in each other and fall asleep watching crappy motel TV.

This had been a particularly tiring hunt, and they couldn't even find it in themselves to even before collapsing onto the bed and crawling under the covers.

That might have been the reason Sam woke up with the need to go to the bathroom. That would have meant that he needed to untangle himself from his fast asleep brother.

Well, previously fast asleep.

Now that same brother was blinking the sleep out of his eyes and leveling a glare at Sam, who had just shifted the cover to get out of bed.

With a grunt, Dean rolled over and wrapped his arms around Sam, pressing himself close against his brother.

"Dean, I have to go to the bathroom", came a whisper from Sam. He tried to release himself from Dean's viselike grip, but failed.

Sam started edging his legs off the bed, but let out a loud sigh when Dean also wrapped his legs around Sam's, completely limiting his movement. As an afterthought, Dean then rolled completely on top of Sam and locked both of his arms around his brother, pinning Sam's arms to his sides. Dean smiled contently and put his head on Sam's chest.

"Dude, c'mon I'm serious. I actually have to take a piss-"

"Hold it in."

With another loud and exasperated sigh, Sam started pulling at his arms and trying to wiggle them out, but Dean held fast.

"Don't go, Sam." came Deans muffled voice. "This is comfy". He wiggled about on top of his brother and wrapped his arms tighter around Sam.

"Yeah Dean, maybe for you it is! But I actually have to pee and if you don't let me go, I WILL pee my pants."

"You're such a baby."

"Am not!"

"Are too!"

"Am n-" Sam stopped himself. It was useless arguing with a half asleep Dean. Sam set his jaw. Desperate times called for desperate measures.

Sam ducked his head down and started blowing onto Dean's neck, who immediately jumped and shyed away from Sam's mouth.

"Aha! I knew you were ticklish there!" Sam exclaimed triumphantly. When Dean scowled at him, Sam gave him a grin.

"Get off Dean, or I'll do it again."

Dean harrumphed but didn't move, which prompted Sam to crane his neck to the left and blow again. His brother released a reluctant laugh and immediately rolled off of Sam, releasing him from his embrace.

The smug look on Sam's face made Dean glare and grumble to himself as he returned back to his side of the bed, which had long since gone cold.

Sam threw back the covers and got up, turning his head back to Dean to gloat, but didn't get the chance to because instead of getting a scowl from Dean, Sam got a pillow to the face.

To say he didn't expect it would have been an understatement. The force of the blow sent him sprawling onto the other bed in the motel room. Before he had a chance to react, Sam felt a weight on his stomach and arms, and looked up to see Dean pinning him to the bed with a sharp grin on his face.

"You wanna play rough, we'll play rough, Sammy", came a low rumble from Dean, and suddenly his hands were at Sam's sides, tickling him ferociously.

The booming laugh Sam let out could have woken a sleeping dragon in the Eastern Hemisphere.

"Stop! Dean stop-" Sam managed to gasp out between laughs and giggles. He tried to tickle Dean back but Dean managed to pin his arms down with his knees, all the while attacking Sam's sides with his fingers. Sam was now laughing uncontrollably, tears almost running down his face.

"Dean if you don't stop I'm gonna pee myself-" Sam giggled out when Dean started puffing huge breaths onto Sam's neck, which only made him squirm and laugh harder.

With a wicked smile and a wink, Dean kept Sam's arm pinned and rolled up his brother's shirt.

When Sam was a baby, Dean would do this to him all the time; he'd blow raspberries on Sam's stomach. It worked like a charm whenever his little brother got upset, always making him laugh. Dean had no idea if it still worked, but he decided to give it a try.

The shrieks of laughter and series of gasps that followed assured Dean that it did.

He did it again and got a similar result, but this time it sounded choked. Dean lifted his eyes to Sam's and was surprised to see that his brother's were wide open in shock.

"Oh crap. Dean I think..."

There was a pause.

"No way Sam. Tell me you didn't-"

The furious blush on Sam's face said it all.

Now it was Dean's turn to start laughing uncontrollably.

The next day, Sam woke up to the sounds of Dean in the shower and the up close view of a newly bought package of extra large diapers on the pillow next to him.
