A/N: This chapter is very short. I originally was planning on posting it with more to it, but then I decided to post this piece as is. I'll post the rest later when I finish.

Months after Cas' return, the angel was sitting on the couch next to Dean. Cas was watching television, and Dean was scanning the sports section of the newspaper. He didn't usually read for fun, but scanning the sports section was somthing he did when he had lived with Lisa. It felt pleasantly normal, and so he was indulging in the leisurely activity when Cas spoke up.

"Dean?"

"Yeah, Cas?"

"I hate being a teenager," Cas responded.

"Why's that?"

"Well... I think this discussion is heading in a direction that you won't like."

Dean looked at Cas with suspicion, over the top of the newspaper. He remembered when he was in high school, and how he tried making out with every girl he could find. He remembered how frustrating it was that teenage girls didn't put out with guys who were going to be in town for only a few days, or weeks. Maybe this conversation was going to be about the sex drive of teenagers. Great! Why was he discussing this with him? Sam would probably be a better choice.

"Are you meaning to tell me your about to talk to me about your sex drive?"

Cas squirmed uncomfortably, as Dean gave him an incredulous look. Dean smirked a little, when Cas' back was turned. He hadn't showed any nervousness discussing things like this before. He figured that it was because Cas didn't go back and forth between heaven and earth anymore. He had been sticking around a lot for the past few months.

"Yes," Cas answered, looking him in the eye. Dean could tell that he was trying to be his old, confident, self.

"Wouldn't you rather be talking to Sam about this stuff?"

"No, I do not."

"Okay, well maybe what you need is a girlfriend, or better yet, a one night stand."

"I'm not very good at socializing. You and Sam are probably the only ones who don't think I'm weird. Besides, I think most women don't want a younger guy, and I can't imagine being with a teenager. I've been around for millenia, and I want to be with an adult."

"Yeah, that's tough," Dean commented as he tried to think of a solution.

"We could always get you a fake ID, and get you laid at least. Oh wait! We've done that," Dean said with a smile as he remembered the disaster of getting Cas laid with a hooker.

"Well, I couldn't help her perpetuate her self-destructive behavior," Cas said in his defense.

"Well, whatever... I don't know Cas, the only thing I can suggest is masterbation. I can always buy you some skin mags. And in the mean time, maybe you'll meet a woman who doesn't think that your strange."

"What's masterbation?"

Dean started laughing. He laughed so hard that tears came to his eyes. When he finished he looked at Cas and his head was cocked to the side, just like always. Dean struggled not to laugh again. Man, it was so frickin nice to have Cas back.

"Ah, hell! Why do you always make me explain these things to you, Cas? Okay, masterbation is- is- well its when you play with your thing to release tension."

"Oh."

"Come on man, don't you have the kid's thoughts to draw on?"

"Yes I do," Cas said, as it just dawned on him.

Cas had never really been affected by his vessel's urges before, with the exception of when he was around famine. But on the last hunting trip, he had seen Dean go into a house with a girl. Her curtains hadn't been drawn completly across the window when Dean and her had intercourse. He had seen them make out, and a few other things. He hadn't gotten a full visual on what was going on, but it had been enough for him to know that he was lonely.

As an angel he had no need to procreate, and had no need or urge to be in a romantic relationship. But after heaven, something had changed him. He had a hard time recalling anything about existance after death, and it seemed that the longer he stayed on this side of the veil, the more things faded. All he remembered was that his feelings of being lonely had been worse in heaven than it had ever been when he was an outcast in this dimension.

Cas was terribly lonely. Dean had gotten him skin mags, but he didn't use them. He wasn't feeling like a horny little teenager. He had told Dean a "white lie". It wasn't about the sex. It was something so much deeper. He wondered if this was how humans felt all the time. He wondered if this was why people had sex so often.

Cas never went back home to where all the living angels were, not because he couldn't, or wouldn't be welcomed. He just felt like he didn't belong there. This was where he belonged, with the Winchesters. But he was still at a loss as to how to get rid of this lonely feeling.
