Alpha Beta Omega... Winchester?

Chapter 4

Dean pulled in to Beacon hills late, around midnight. Sam was sleeping and Cas seemed restless in the back. Once Dean found the small town's motel he parked and patted his brother's shoulder. "Hey Sammy. Wake up." Sam rubbed at his face and sat up, looking around.

"I'll go get a room." He said and yawned as he got out of the car. Dean looked back at cas and furrowed his eyebrows.

"Cas... You okay?" He asked. The expression on Cas's face... He shifted as if uncomfortable.

"I feel... Strange..." His head was tilted. Dean turned in his seat to look at him better.

"Like what? Pain?" Cas shook his head.

"No... Tingling maybe... I can't sit still." Dean thought for a second.

"Where is it?" He quickly wished he hadn't asked. Cas pointed to his bladder but also described it at the tip of 'the strange thing males have'. Dean actually blushed. Did the Angel... Have to pee? Angels don't do that... But Cas had been losing his grace and power... What if he was becoming human? "Uh... Ok... Um... When Sam gets the room we can... Take care of it. I think you have to piss." When Cas gave him a troubled look he sighed. "Piss? Pee? Urinate?" Cas then got it and nodded.

"But... I'm an angel. Why would I have-" A small gasp cut if his speech and Dean looked down to his crotch were the smallest wet spot was.

"Yep okay... Just... Hold it okay? Don't let it out." Cas nodded and squirmed, and instinctively wrapped a hand around his cock through his pants. Dean quickly looked away. "Ok here comes Sam." He got out and went up to Sam. "Um... Cas has to pee... I think he's turning human or something but he has to go pretty bad and doesn't know how and..." Dean was talking pretty fast and Sam chuckled.

"Dean calm down. Just teach him how. He is your angel... Well maybe human now. Or soon." He was setting Dean up. "Here's the key, I'm gonna go get some food." Dean tried to protest but Sam was walking away. Cas got out of the impala and went up to Dean.

"What do I do?" Dean sighed and motioned for Cas to follow and opened the door, going in and closing it behind them. He pulled off Cas's trench coat.

"Do you know... How to go?" Cas shook his head. Just great. "Ok... Follow me." He brought Cas into the bathroom and lifted the lid. This was going to be miserable. "Ok... So you take your dick out of your pants, point it as the bowl... And go." Cas looked so confused.

"I don't understand... Dean please help it hurts." He was actually whining. Dean knew Cas would wet himself if they didn't hurry. He unbuttoned and unzipped his own pants.

"Do as I do." Cas nodded and did the same. Dean reached into his pants and took hold of his penis. Cas found his and looked up. Dean really didn't want to pull his out... But Cas wouldn't care so he did with a blush. "You take it out, come up to the bowl and aim it at the water. Cas pulled himself out and Dean froze. In his flaccid state... He was huge. Bigger than Dean. Dean swallowed and looked back at the toilet. "Then you just relax your lower muscles and let it come out." It took him a second to be able to go, being watched, but he did. Cas watched for a moment before getting close enough to the toilet and aiming. Cas jumped as he started peeing but managed to keep good aim. God was this awkward. Dean finished and waited until Castiel did as well. "Then er... You shake it and put it away." He quickly did this and zipped up, and watched Cas do the same. Then he flushed the toilet. "And that's it." His cheeks were very red. Cas smiled.

"Thanks Dean. You're so helpful." Dean nodded a bit and quickly walked out. God Cas was big... And when he was hard? Thinking about it made Dean shudder and suddenly he was hard in his pants. And of course at the very moment Sam came in with the food. He saw Dean's boner and smirked, but acted like he didn't know. Dean turned away and quickly flipped it up to make it less obvious.
