It had been a long day. Hell everyday was a long day. They had learned from a young age that sleep was a luxury, but they had someone who allowed them to get sleep at least. Someone they trusted. Without him they would probably never sleep. But sleep was far from Dean's mind. Something had changed during the long hours of that day and the cold hours of that night.

Dean, Sam, and Cas had split up to complete the task at hand, and with Cas being an angel, he quickly finished what he had to do and went over to help Dean. Dean was caught by surprise when he turned a dark corner, a corner he had just checked and was completely positive that no one was there, and found Cas standing in front of him.

"Dammit Cas," He whispered angrily, "I almost shot you. What did I tell you about doing that?"

"Sorry," Cas said, his eyes falling to the floor.

Dean looked at the innocence in Cas's face and felt bad for how he reacted. Cas was always there for him, always had his back, and he his, but there was a strange new feeling between them, something that Dean couldn't quite figure out… Or didn't want to.

"Why are you here?" Dean asked, his tone changed adding a hint of concern.

"I made the traps like you asked. It was a very easy task to complete… Dean?" Cas said, and Dean flinched a little to the sound of his name coming out of Cas's Mouth.

"Yes, Cas,"

"When I said that I wanted to be a hunter…I didn't know it would be this easy," He said and Dean smiled.

"Well, I guess when you're an angel, hunting Casper and friendly demons isn't that hard." Dean said with a laugh. He liked how Cas was clueless about how it is to be human.

"Demons aren't friendly, Dean." and again Dean smiled.

Dean continued to walk about the house with Cas following silently behind him. Dean could feel Cas looking at him. He could feel his eyes staring at the back of his head, and Dean imagined Cas with his confused face that reminded him of a lost puppy. Dean shook his head, What is wrong with me? He thought. He turned around to take a look back at Cas, to see why his stomach was acting strange, why his throat had tightened. He knew he wasn't nervous… this was an easy hunt, all they had to do was catch this want-a-be demon that was playing tricks on everyone, yet he couldn't shake this feeling, couldn't distinguish it among all the other feelings he's ever had. Cas was so close to Dean when he turned around that their noses grazed each others, sending a strange sensation down Dean's spine. He flinched away, confused with how his body had betrayed him, confused as to why he felt the need to be close to Cas again, to be near him, to touch him.

Dean shook off the emotions he was having, and tried to convince himself that he was just happy that Cas was back, that he didn't fail him, but even when he tried to convince himself that it was just that, something would happen that would contradict all those feelings. There were a few times where Cas would walk in front of Dean then turn around with an expression asking if he was doing the right thing, and every time Dean would smile, a crooked smile and look Cas up and down. Each time Cas attempted to act like a hunter it made Dean laugh. He found it adorable… He shook his head again, disgusted with where his thoughts were taking him.

By 10 pm they had found, caught, and exercised the demon. Sam and Dean were exhausted, even if it was the easiest hunt they'd had in months. They went back the motel, Cas trailing behind the sluggish boys and Sam collapsed on the bed. As soon as Sam's head hit the pillow he was out.

Cas watched as Dean took off his Army green jacket, then took a seat in the brown oversized chair. He watched as Dean rubbed his eyes while leaning forward with his elbows resting on his legs.

Dean looked up and caught eyes with Cas. They looked at each other silently, Dean was trying to read Cas's round eyes, the ones that watched over him, and there was a sudden change. He didn't know why it had taken him this long to figure it out… He loved Cas. There was no other explanation for why he was feeling this way. He stood up becoming eye level with Cas and walked toward him.

"Good job today," Dean said. He stopped just a foot away from Cas.

"Thank you, I learned from the best," said Cas.

Dean half smiled, "You, know… I'm glad your back. It wouldn't be the same without you. Me… Sam… We've lost everyone. And when I thought I had lost you too… I just…"

Dean didn't know what to say. He wanted to open up to Cas, wanted to tell him that he loved him, that he never wanted him to leave. He was afraid though. Because just like everyone else in his life… every single one of them left. All he had was his brother, but he knew he would always have his brother, even when they were at each others neck. But he needed Cas to stay in his life for a different reason. He wanted Cas.

"Can we go outside?" Dean asked as he grabbed his jacket.

Cas nodded and they went out.

"I… I…" Dean tried to get out. "I don't…

Cas walked closer to Dean and Dean shivered. His stomach turned in knots and his eyes fell to the floor. "I don't want to lose you," Dean said, and it was the closest he could get to saying "I love you."

Cas placed his hand on Deans chin and brought his face up to his. He looked into Deans eyes, and in that second he knew what Dean really meant. He leaned forward and placed his lips on Dean's forehead.

"I will never leave you Dean." Cas said, his lips softly brushing against Deans forehead.

At that moment Dean placed his left hand on Cas's back and his right through his hair. He pulled Cas as close to him as he could and pressed his lips hard against Cas'. There was an immediate reactions from Cas that made him feel weak, yet powerful all at the same time. He put his hands on Dean's back and tried to bring Dean closer. He heard Dean gasp and he loosened his grip. He had forgotten how strong he was. He readjusted his hands and placed them on Dean's waist then walked forward, pushing Dean into a wall.

Dean pulled away from Cas for a split second to take in a breath then leaned back in with more passion then he had ever kissed anyone with before. He craved more, he spun around and put Cas against the wall letting his hands slide down Cas' body and to his thigh. Dean grabbed Cas' legs and picked him up, bringing him over to the door of their motel. He pushed open the door and carried Cas along. He threw Cas on the round table and pushed his hips forward into Cas', knocking over the keys to the impala and a glass of water . The items hit the floor with a thud and Sam stirred in his bed. Dean broke away from Cas's mouth and looked over to Sam, Cas' lips went to Deans Neck. Sam was slowly waking back up. Dean let go of Cas and stumbled back a little away from him. He knew that what had just happened was wrong, yet he craved more.

Cas stood there, clothes and hair a mess, and he smiled.

"Next time we'll get our own room," Cas said, and Dean with a confused expression on his face nodded

"Yeah, that would be best." He said out of breath.
