Hello again. So here's another chapter for you. Enjoy.

They had sat at a booth next to the window in the diner and Dean was perusing the menu, looking for food for both himself and Cas when the very pretty waitress came up to their table smiling flirtatiously at him. And Dean, being Dean, flirted right back.

"Hi, what can I get you this evening?" She asked seductively making it clear to him that if he wished she had something very special that wasn't on the menu that he could have.

"Hey there, Beth, can I get a bacon cheese burger and –" Dean started to say only to be interrupted by a very pissed off voice.

"Make that two please." Castiel practically growled at the waitress. What the hell?

"Of course. And to drink?" Beth the waitress turned back to Dean with the question, batting her eyelids at him while Castiel narrowed his eyes at her. She was not right for Dean so she should leave him alone.

"A couple of sodas please." Dean replied stilling smiling at her but his attention was now split to watching Cas. He had never seen the other man behave this way to anyone. I mean he was so nice and kind to everyone. So why in hell was he glaring at the waitress like he wanted nothing more than to remove her from the face of the earth? Once the waitress had left Dean turned all his attention to the man who watched the waitress walk away.

"What the hell Cas? Why you so mean to her? What did she ever do to you?" Dean demanded of the man across from him.

"You should not be flirting Dean, we are in a relationship." Castiel explained sounding out every syllable of the words so Dean could not pretend to have misheard.

"Oh god, you're jealous." Dean said in disbelief a slight chuckle in his tone. He had never had anyone jealous over him before.

"I am not, I am just stating a social behaviour you should be observing due to our change in circumstances." Castiel ground out at the human and crossed his arms. Why would he be jealous? He knew that the flirting meant nothing after all, plus he was not here to be with Dean but to teach him how to be with another.

"Yeah right." with that Dean leant over to take Cas' hand in his own. "Look Cas, you have no reason to be jealous alright?" He said gently and when Cas just carried on glaring at him he continued. "Let me prove it to you." with that Dean leant in further and kissed him gently yet firmly. There was no mistaking what it was. It was a kiss of two people who were together. "She is nothing compared to you, angel." Dean breathed across Cas' lips as he pulled away from the other man who hadn't responded, though whether that was because he didn't know how or if he was still pissed at him Dean had no idea.

When Dean called him angel Castiel's facial expression went for glare to frown of confusion and his head tilted to the side. There was no way the Dean could know, was there?

"Why did you just call me angel?" He asked cautiously.

"It's a term of endearment Cas. What don't you like it?" Dean asked sitting back and looking at the man across from him who was, without doubt, an angel in Deans mind.

"I don't know." Castiel replied. Yes he knew it was a term of endearment that humans used, but he wasn't sure he really wanted to be called by his species by Dean. Which was a strange thought, because it meant nothing.

"Okay Cas, that's okay. I wouldn't call you it again." Dean replied seeing the frown of confusion on Cas' face and not wanting to upset him. It seemed he had done enough of that by flirting with the waitress. Hmm, he was going to have to remember to stop doing that from now on if Cas didn't like it.

"Thank you Dean." Castiel replied and made a concerted effort to remove the frown from his face as he smiled up at the human, though looking into those green eyes he found it wasn't that hard. It wasn't until much later that he thought over what had happened and wondered if there was any chance that Dean may have been right. Was he jealous?

They finished their dinner, with Dean refusing to look the waitress in the eye again, and made their way back to their motel room. Dean was getting surprisingly nervous. Though he didn't know why. It wasn't like he had never kissed a guy before or anything like that. But still, this was different. This was Cas, and he had no idea of what he was doing.

Once they got back into their room Dean went and grabbed a couple beers for them both then led Cas over to one of the beds and sat him down next to him perched on the end.

"So, you want your kissing lesson now?" He asked casually looking at the man out of the corner of his eye as he took a drink of his beer.

"Yes please Dean." Castiel replied also taking a drink, though mainly because it was what Dean was doing.

"Okay." Dean replied, though all the movement he did was to take another, larger swig beer before he spoke again. "So first, umm, well what do you know of kissing?"

"It involves two people putting their lips together." Castiel replied seriously. That much he did know.

"There's a little more to it than that, but yeah that's the basics." Dean said with a chuckle before becoming serious and turning so he was facing Cas. "Okay, so I'm going to kiss you, just follow what I do."

"Very well Dean." Castiel replied with concertation in his voice.

With that Dean took a deep breath and put both their beers down on the floor before he ran his sweaty palms down his pants legs, he then raised one of his hands and framing Cas' face tilting it up slightly for ease of access. He then lowered his lips to the other man's gently pressing them together. At first Cas was a passive participant in the process but soon Dean felt a pressure equal to his returned against his lips. At that point he started to move them against Cas', tilting the other man's head so that they slotted together into a better position. When Cas responded well to the new position and the movement he flicked his tongue out to run it against the seam between Cas' lips to get him to open them, yet nothing happened, but then he realised that of course it hadn't, Cas had no idea what that meant. He was about to pull away and explain when Cas' tongue darted out imitating his. As such Dean open his mouth, pulling Cas' tongue inside. It didn't take long for Cas to understand what was happening and soon the other guy was kissing Dean back with the same reverence and muted passion as Dean was kissing him. Wow this guy really was a fast learner was the only though that went through Dean's mind, after that there were no more words, just feelings. Amazement that he was doing this, kissing Cas and being kissed back. Joy and pleasure at the feel of Cas' lips against his, one of his hands on the side of Deans face mirroring how Dean himself held his own. He also strangely felt contentment. Yes obviously he wouldn't so no to anything more, but he didn't feel the need to seek it. Usually for him kissing was a prelude to other, more explicit things. But with Cas, it felt as if this was the main event. There was no need for anything more, cos this was without doubt awesome.

Castiel sat next to Dean and waited for him to start the lesson. He hoped that this worked and he showed Dean what could be, that not everything was all about sex. But there was also another part of him (the part that like the idea of trying different food), who wanted to experience this act that humans seemed to do without thought. Now he was allowed to try, he couldn't wait to experience some of what his charges' feel when they first met their pair. Not that he and Dean had that relationship, but it was the one he was trying to model so Dean would accept it when he did. So he sat there and waited for Dean to kiss him. At first he was not sure what to do, Dean had just told him to follow his lead, but what did that mean? He did not know, so he just returned the pressure exactly. This seemed to please Dean and he moved to do more, tilting his head so that their noses weren't bumping together. And then Dean ran his tongue over the seam in his lips. Castiel didn't know what that was for but he did the same to Dean, thus finding out exactly what Dean had wanted from him. Opening his mouth and mirroring the humans movements of lips and tongues he sat there and enjoyed the feel of the contact with Dean as well as the feel of the emotions he now had coursing through his body as they poured off of Dean, though he did once again feel those strange feelings which seemed to be separate from Dean, but he put them from his mind to be looked into at a later date. No now he was just going to give his all to the enjoyment of learning such a human thing as kissing.

Dean finally pulled back from the kiss flushed and panting, though looking at Cas he saw the man barely looked any different, though his hair was a bit more messed up where Dean had been running his hands through it.

As Dean pulled away it seemed Cas didn't like that idea and tried to follow him.

"I need to breathe Cas." Dean managed to get out as he kept his lips out of the reach of Cas' questing ones.

"Of course Dean. I am sorry." Castiel replied leaning back so he was sitting normally and putting his hands in his lap. He had forgotten that Dean was human and as such needed to breathe. He needed to remember these things, and he needed to remember that he too should have the need to breathe.

"Hey don't apologise Cas. You obviously just have a better lung capacity than me." Dean replied with a smile of reassurance at the other man, a smile which quickly turned into one of an emotional feeling that Dean refused to name, though his heart screamed it was love, before he bent his head once more and continued the lesson.

And that was how Dean and Castiel spent their night, though they soon moved so that Castiel was leaning against the head board of the bed and Dean was lying across him so that they were both more comfortable as they continued to kiss. And kiss they did, right up to the point where Dean's eyelids started to drop and sleep took him over, and when he finally succumbed to slumber he was still wrapped in Castiel arms, lying on top of him, with his head resting peacefully on Castiel's chest.

Castiel looked down at the sleeping man, he knew he had a lot of things to think about, and he needed to go back out and search for Dean's mate, but he also knew he could not move without waking his human. As such he decided rather than trying to analyse feelings, or searching for partners, he would spend the night just where he was. Watching Dean sleep and easing his dreams with a soothing hand running through his hair. As such Castiel laid back with a smile on his lips and held Dean tighter against him. Yes, this was very pleasant.

And up in heaven Gabriel lay on a cloud bored out of his brain as he flicked through scenes of recently paired humans and those currently on their books as you would flick through TV channels when looking for something to watch. When he got to the scene of Castiel and Dean sharing a single bed he stopped to observe, looking down he saw the serene smile on his brother's face which made him look closer. Opening the sight which all angels had to give them the ability to see the bonds they were making he saw a tendril of Castiel's grace reaching out for the soul in his arms and a similar tendril from Deans soul reaching to Castiel's grace. One look and Gabriel brought his sight back to the physical. He knew that he should go down there and intervene, remove Cassie from Dean, angels were not supposed to fall in love with the charges after all, but looking at the happiness on his brother's face and Gabriel knew he couldn't do it.

"You never make things easy do you Cassie?" He muttered to himself before he flicked to the next scene leaving Castiel and Dean in peace. He would deal with the fallout from this when the time came. For now he decided to just let them have the happiness that they had found, they both deserved it after all. Hmm, he had been right at least. Castiel was the only one who would succeed in finding Dean his soulmate, though he hadn't realised at the time that that was because Cassie could well become said soulmate.
