A couple hours before Dean, Sam and Castiel had gone out to a bar to celebrate. To summarise what happened, Dean got very drunk, he had to be carried to the impala by both Sam and Castiel. Sam drove them back to the motel and that is where we are now.
Sam had put Dean bed and watched as he quickly fell asleep while drinking a cup of water, he didn't want anything to happen like the last time he was that drunk (he went out for a walk and was found in a park that was five miles away from them). As Castiel was human too he needed to sleep, he only had a beer while they were at the bar unlike Dean.
"Alright Cas im going to go to sleep too, don't wait up. Remember you are human and you need to sleep" said Sam as quietly as possible to not wake Dean.
"But i need to watch over you two"
"No you need to sleep, we are safe here"
"But-"
"Castiel we talked about this"
"Okay Sam i will go to sleep as you wish, i still don't understand the need to stay in a position for hours on end with your eyes closed"
"Good"
Castiel nodeed, he took his coat and shoes before going under the covers and resting his head, his bed was opposite Deans as he still wanted to watch over the Winchesters, he lied down and watched as Dean slept. Soon he was fast asleep himself, as much as he didn't like or understand the concept of sleep he still needed it.
It was one in the morning and still drunk Dean had woke, he stood up and rubbed his eyes, he took a few steps towards the kitchen and grabbed a glass to fill with water. He turned the silber tap letting the water run into the glass as he held it underneath. He took a big gulp and placed the glass into the sink. He stated to walk back towards where Sam and Castiel were sleeping, he took a look around and rubbed his eyes, he started to walk towards the and tried to not stumble over as approached what he thought was his bed. He sat down on the right side of the bed and rubbed his forehead, he tool a deep breath and closed his eyes and lied down. He placed the white covers him over he felt a warmth besides him and decided as he was cold from walking around to get warm. He turned and draped his arm over the unknown warmth, it was so warm so he decided to get closer to it.
"Em, Dean is that you?" Asked a quiet voice
"Yes who is asking" mumbled Dean
"Castiel, and what are you doing"
"I went up to get water and i ended up in the wrong bed, are well its warm and comfortable here and i like it here"
"Dean your drunk-" wispered Castiel as he turned to face Dean.
"Shhh im trying to sleep" Dean pulled Castiel closer to him and they were practically hugging at this point.
"Dean i cannot breath, you are suffocating me"
"Shhhh Sammy is trying to sleep" Dean patted his head and hugged him tighter.
"Can you atleast let me go a bit so i can breath"
"Alright" Dean let him go a bit but still had his arms wrapped around him, Castiel took his head up from where Dean had pushed him into and looked at him, Deans eyes were still closed but he had a small smile on his face. Castiel managed to move his arms and he wrapped them around Dean.
"See i told you its comfortable here" whispered Dean
"Shut up i am human and i need to sleep too" replied Castiel
Dean let out a small laugh before burying his face into Castiels sholder and slowly falling asleep, Castiel too buried his face into Deans shirt.
The next morning Sam had woke up not noticing his brother snugling with Castiel. He went to make some coffe and came back into the room to wake them up, he froze as he saw what was Dean and Castiel sleeping in the same bed inches away from eachother, they were practically on top of eachother.
"God dammit i knew it"
