Dean grumbles, as he feels the morning light seep through the curtains, hitting his face. Surely it's not time to wake up yet? It doesn't even feel like 5 minutes since he fell asleep. And his head is killing! It's like someone whacked him over the head with a hammer while he was sleeping. And Dean can usually handle his liquor pretty well, so it begs the question: how much did he even drink last night?

As his mind begins to waken, Dean knows he won't drift back off now. Still, he rolls over, determined to rest for a little longer.

But suddenly his eyes shoot open in panic.

He can feel the breath of someone next to him.

"Cas?" Dean rubs his eyes, as he forces them open in his sleep-deprived state.

"Good morning, Dean," the angel states, quite calmly.

"Dude!" Dean exclaims, as he pushes himself back across to the other side of the bed. "Are you naked?! Why are you naked, Cas!"

"You're naked too," Cas points out, as he lies on his side, watching Dean.

Dean briefly looks down at himself, realising the angel is right. Instinctively, he pulls his covers up over himself even more, right up to his neck.

"What the hell happened last night?" Dean hisses, even though he knows the answer already.

But Castiel doesn't respond, he just simply grins.

"I am sore in such weird places…" Dean mutters to himself, as he finally becomes fully conscious. Despite his banging headache, the hunter's main focus right now is an unusual feeling around his peachy ass.

"Did we…" Dean's eyes widen in shock, as he realises what must have gone on last night.

"Dean?"

Sam's voice can be heard from up the hallway, and Dean panics.

"That's Sam!" he hisses at Cas. "You have to hide, now!"

He fusses about, trying to shoo Castiel out of his bed, but the angel isn't budging.

"NOW CAS!"

Too late.

"Dude, what the hell?!" Sam exclaims, as he enters the room, to see the pair of them under the covers together.

"Morning Samuel," Castiel calmly states, with a huge grin beaming across his face.
