A/N: I'm a new fan of Supernatural but was of course instantly obsessed with the chemistry between Dean and Castiel. This is my first m/m fic. I came up with the idea while watching the episode My Bloody Valentine. It's suppose to take place at the end of the episode when they lock Sam in the bunker and Dean is upset and walks off. I do have other stories lined up to continue their relationship after this. They will take place in multiple seasons. (after Cass's appearance in season 4 obviously) Sometimes full seasons apart. Lets see how this one goes.

Disclaimer: I own nothing but the idea. Cass and Dean belong to the creators of Supernatual.

I stand there wet from the rain staring up into the sky waiting for something to happen, even though I know nothing will. I can taste the salt from my tears and I try to wipe them away but they just keep falling.
"Dammit!" I say to myself as I kick my cars tire.
I just shake my head and look around. Alone. I've been feeling lonely for sometime now but it only truly sunk in today how alone I really am. Even a fucking angel needed something. But not me I need everything and nothing. I start to pace in the mud trying to think of something I want, need ,anything that I truly crave. To sleep with some random chick? No I don't need meaningless sex at the moment. Some type of food? I could always go for some pie. I look at the bottle of whiskey I had placed on the hood and sigh. It's kept me numb this long I think as I take a long swig. I look up at the sky again and and close my eyes just focusing on the feeling of the cold rain hitting my face.
"Cass was right." I say into the open air, "I don't believe I was worth saving. I know your plans for me but this just proves I'm not good enough." I look down at the ground again and choke back a sob, "I'm never good enough."
I tug at my short hair and kick my tire a few more times. I sigh and rest my hands on the hood and just hang my head. I feel a hand on my shoulder and I expect it to be Bobby. Although I'm unsure of how he would have wheeled up on me silently.
"Cass." I say as I turn around and meet his blue eyes.
"Have you been crying?" He says more like a statement than a question.
"No of course not." I answer and instinctively wipe my eyes and face.
"Your eyes are puffy." He says and puts a hand below my eye.
I'm surprised at how warm he feels compared to the rain but the feeling that surges through me startles me more.
"Are you alright?" He asks taking his hand away.
"I'm fine." I say curtly as I stare intently at his hand hanging at his side.
"You don't look it." I reach up and wipe my face again.
"It's raining." He says profoundly.
"So?"
"So, no matter how many times you wipe your face water will keep appearing on it."
I can't help but smile.
"What?" He asks giving me an odd look.
"Nothing, nothing." I tell him still smiling at the confused look on his face.
"Would you like to talk about what's wrong?" He asks as his expression turns to concern.
My smile drops and I swallow hard. I can't speak. He's gaze is boring into me and I don't know if I can lie to him.
I can feel the tears start to form again and I can't seem to blink them away.
"You're crying again." Cass says taking a step closer to me.
"How can you tell it's raining?" I ask with a trembling whisper.
"I know you better than you think Dean."
I turn my head away when I feel more tears running down my face. I'm about to say a witty retort when I'm shocked to feel Cass's arms around me.
"What are you doing?" I ask.
"Hugging you. Isn't this what you're suppose to do when a human is in pain?" Cass answers in that deep raspy voice of his.
"Yeah you are but then again you're not human." I reply as I wrap my arms around him.
"Am I doing it wrong?" He asks.
"No, no you're doing it perfectly." I answer.
My breath quickens and I start to feel like I'm having a panic attack. I bury my face in his shoulder and I start to cry again. Only this time I let the tears fall at will.
"There, there." Cass says as he awkwardly pats my head.
"I'm sorry." I say against the wet fabric.
"There is nothing to be sorry about human emotions are complex."
I pull back a bit and just stare.
"What?"
"Nothing it's just..." I let my sentence trail off.
"Just what?" He asks.
"This is the first time in a long time I haven't felt alone."
"You're never alone Sam is pretty much always with you."
"I know that but it's difficult to explain but I just don't feel a connection I guess. It's like he's there but he might as well not be."
He just nods slowly like he's giving this a lot of thought. I notice then that our arms are still around each other. But I'm afraid to say anything because I fear I'll feel alone again as soon as he lets go.
"For your information you Dean Winchester were worth saving." he tells me with a weak smile.
I return the smile but the tears keep falling.
"How can you be so sure?" I ask.
"You are stronger than most humans and I do not mean physically but emotionally. You must remember that I have seen your soul and whether or not you have something to do with saving your beloved planet and the order that has maintained it you are destined for great things."
I feel one of his arms slide away from me and just when I'm about to object I feel his hand on my cheek and his thumb is brushing tears away.
"Thanks Cass." I say as I nuzzle my cheek into his hand.
I lean forward and place a light kiss on his cheek.
When I pull back away Cass's eyes are wide with curiosity.
"I'm sorry." I say quickly.
"No need to apologize I am just unfamiliar with this type of contact. Is this a normal human thing to do?"
"Yes we do this to people who deserve it. People whom we love."
"You love me?"
"Yeah I suppose I do"
His eyes are wide again but this time it looks like excitement. I see him leaning forward and I turn my head just in time to catch his lips with mine. We stand
there for a moment lips touching but not moving. I think i should want to pull away but the electricity I feel pulsing from him stops me. I suddenly feel more pressure and Cass pushes up against me. I'm shocked that he is doing this. Advancing on me but who am I to deny an angel of God. I move a hand to behind his head and pull him closer to me. I open my lips slightly and let my tongue slip out to lick his. I'm surprised at how fast he grants me access and I move to dance my tongue with his. It's awkward at first since he doesn't really know what he's doing but he quickly figures it out.
After a few minutes I need to pull away to breathe. I lean my forehead up against his.
"Do you kiss people like that often?" He asks just as equally out of breath as I am.
"With my tongue yes. With that much feeling no."
His eyes stare into mine and he moves again to kiss me this time lightly and only a few seconds.
"Cass I'm afraid if we don't stop now I won't be be able to." I tell him.
"I don't think I want to stop." He says brows furrowing like he's deep in thought.
"I haven't felt like this in a long time. I don't think I want to stop either."
"Well then why are we wasting time." He says urgently and leans back towards me.
"Because if we keep doing this I don't know if I'll be able to stop other things from happening. I'm not sure if I want to stop more from happening." I say as I put a hand on his chest to keep him away from me.
"More?" he asks.
"Yes you know more things that guys can do to each other. Kind of what a girl and a guy do together minus the girl and add another guy."
"Show me."
"Cass are you sure? Isn't this against the rules?"
"I have not heard of a rule that forbids this but I am not suppose to deny my host anything it wants."
"Well then I'll just have to make sure I meet your needs."
I move my hand from his chest and place it on his hip and pull him close to me. My eyes widen when I feel his erection pressed against mine. He looks down at the contact.
"I'm sorry I'm not sure what happened." Cass tells me.
"It's okay it's better than okay actually. It means you're body wants this. It's responding to my touch." I explain.
"Responding?"
I just smile at him and move my lips to his neck where I gently kiss, lick, and nip. I feel him stir against me and I trail my lips up to his ear.
"Can you feel your body respond when I do this?" I say as I blow into his ear and then suck and bite the lobe.
His moan is my answer.
"That sound just kind of happened. Is that suppose to happen?" He asks between his short breaths.
"Yeah, that means you like it."
I move to kiss right below his ear and that causes another moan to slip out. I smile against his skin. I feel Cass's fingers in my hair and I'm taken back by how roughly he pulls my head up to look at him.
"You are never alone Dean. Do you hear me? I am here for you." He says before he pushes his lips hard against mine.
His tongue finds my lips quickly and I happily let him enter. He takes his time and explores. I can't seem to get enough of the taste of his tongue. I'm sure I only taste like whiskey to him. I breath in slightly through my nose and I can smell him. He smells like freshly cut grass after a summer rain.
I smile against his mouth and move one of my hands to cup his ass. He pulls back and stares at me with surprise before shoving me hard against the car. His lips are on my neck. Biting and sucking. Then on my ear. Blowing and licking. I can't help the moans that escape me and I hear him chuckle with each one.
"I guess your body is responding to me as well." He says before moving to kiss my Adam's apple.
"You couldn't tell by this?" I ask as I grab one of his hands and make it rub against the tight bulge in my pants.
He grabs it lightly and continues massaging my erection.
"Cass." I manage to moan before he reclaims my lips.
In one swift move Cass has me sitting on the hood of my car with him standing between my legs. He seems ravenous as his hands move around my body. I put my hands on his shoulders inside that ridiculous trench coat and begin to slide it off.
"It's raining." he proclaims pulling away from my lips.
"You're so obsessed with the rain." I answer reattaching myself to him.
"If you take my jacket off in the rain I will get very wet."
"Well I plan on making you very wet anyway but okay give me a second."

I push him away from me while I hop off the car and dig in my jacket pocket for my keys. I unlock the car and hold open the back door for him. He happily slides in with me following. I immediately slide my jacket off and place it in the front seat. When I look back to Cass his is off as well as the suit jacket. I just stare at him for a moment. What am I doing? I'll admit that I've felt drawn to him many times. Hell I've been using almost any excuse to call him to us. But doing this. Taking advantage of an angel. I've never been so low before. I can't believe I'm doing this. Especially to a male angel. I've never been with a guy like this. I've flirted with a few to get something from them but it's never gone past that. I look up and down his body stopping only to look into those blue eyes.
"What's wrong?" He asks narrowing his eyes.
"I've never done this before." I tell him.
I place a hand on his chest and I feel it rise and fall quickly. I swallow hard and move a hand to undo his tie. When it's loose enough I slide it over his head. "You know I haven't done this before either." Cass tells me as I throw the tie behind me.
"I'm pretty sure I could have guessed that." I chuckle.
I look deeply into a sea of blue and I can't help smiling. He smiles back. I run a hand through his hair and along his cheek stopping only to trace his lips. I move towards him and place a leg bent on the seat on either side of him. Straddling him. I slowly lower my weight on top of him and instantly his arms are around me. Holding me. Glueing me to him.
I cup his face in both hands and lean forward until our foreheads and noses are touching. I move slowly and lightly place my lips against his. He kisses back gently and moves one hand to my face pulling me closer to him. I remove a hand from his cheek and use it to begin to unbutton his shirt. He takes the hand from my face and does the same. As I feel him undo the last button I slide it off leaving me in a black tank top. I slide his off as well revealing his white tank top. I swallow again and lean forward to kiss his collar bone. I lick along his shoulder and stop to bite occasionally. He puts his head back and moans as he begins to wiggle underneath me
"Dean..." he says between heavy breaths, "I'm not feel very comfortable."
I smile and lean in to kiss him deeply.
"We'll feel better without pants on." I say pulling away slightly.
In an instant I feel a chill on my legs. I look down we're both in boxers. I always imagined him in tighty whiteys.
"This feels better." He says.
"Pants can be restricting when you're hard." He just pulls me back to him.
Lips instantly against lips. Then trailing along my jaw. Down to my neck where he takes his time to taste my sweaty skin.
"I understand now why some people are cannibals." Cass says pulling away to look at me.
He licks his lips and I can't help but laugh. I move quickly and crash my lips into his biting his bottom lip slightly. I move a hand down to his stomach and run a finger just inside his boxers waist band. He moans loudly into me and tries to push up into my hand. I chuckle and slide another finger in. This time sending them deeper almost touching him.
"Dean please." He begs.
I smile and remove my hand. I place it against the outline and grab. He gasps suddenly and I move to bite his neck.
"No clothes" I tell him quietly.
Suddenly I feel the unrestricted heat from his erection against mine and I grind into it. Cass throws his head back with his mouth open and I can't help but relish the sight. I place a hand behind his head and pull him to me. But he seems to reach my lips first. This time something is different. He seems more hungry for me. He is pulled close against me and shoves his tongue deep into my mouth completely over powering me. He kisses down my chin and neck. He bites harder this time. I know I'll have a few bruises. He moves further down to my chest. Placing kisses all over it. He hesitates for a minute before biting my nipple. I throw my head back and moan loudly. The hand I have on his head grips his hair tightly.
"How in hell did you know to do that?" I ask between shallow breathes.
"I guessed." He answers looking up at me.
I lean down and kiss him lightly.
"I need you." I whisper.
"Need me how?"
I look deep into those blue eyes and seem to get lost. I lean down and kiss him again this time forcefully.
"I need you Cass. All of you inside me." I tell him.
His eyes narrow and he looks at me confused for a few moments before they open wide.
"You want me to... to be inside you?" He asks looking between me and the hard cocks between us.
"I'm sorry I never should have asked."
I feel regret rise in my gut and start to consume me. I never should have thought that an angel would participate in an act like this. I begin to pull away from him but his arms go around my waist and keep me still.
"I never should have pushed you to do this Cass I'm sorry. We can pretend this never happened." I tell him trying to move his hands.
One of his arms moves to behind my head and forces my head to his where he kisses me hard. Tongue demanding entrance. He pulls away suddenly and stares at me.
"You did not force into anything. I think I've wanted this for some time. I'm drawn to you. And if you would like me to be your first I would be honored. But I do not know what I'm doing or even where to begin." he tells me in a reassuring voice.
I just stare at him in disbelief. Did an angel really just admit to lusting after me?
"We take it slow. Do you understand what I'm asking?" I ask looking into those blue eyes again.
He responds by kissing me hard tongue intertwined with mine. I feel his hands travel to my waist and then farther until he has my ass in both hands massaging it.
"Hold on." I tell him pulling away.
I lean down to under the seat and pull out a black bag. I take a bottle of lotion out of it and place the bag back on the floor. I grab one of his hands and pop open the bottle.
"One at a time. I need to be stretched a bit." I tell him as I squeeze it onto his fingers and lather them well.
He just kind of nods at me looking uncertain. I lean down and kiss him. His lotioned hand makes it's way back to my ass. I pull away to take a deep breath and I see him swallow hard. I drop the bottle of lotion onto the seat next to us.
I close my eyes at the feel of his finger circling my entrance. He breathes out and slides the finger in a little bit. I feel him watching me. I don't react to the little bit of penetration so he slides it the rest if the way in and leaves it still for a moment before moving it in and out. I moan as he picks up speed. I feel his body relax some. And he starts to move it around hooking the top of it. He pulls his finger out of me and begins to enter me with two. My back goes straight and I suck in some air. Cass automatically removes his fingers.
"No, no don't stop." I tell him.
"You want me to hurt you?" He asks with a concerned look on his face.
"The pain will fade once it does it will feel better." He swallows again and slowly moves his fingers to back inside me.
I close my eyes again and try to focus on my breathing as his fingers go deeper. When they're in fully he leaves them still for a long time while he kisses my neck, shoulders and chest.
Finally he moves them slowly in and out. Then scissoring them. As he starts to move them in and out faster I moan loudly and I feel him smile against my skin. He begins to fuck me with them moving fast and hard. Burying them deep inside me. He slips in a third finger and my head goes to his shoulder where I bite. He moves his hand slowly and precisely. He build momentum as he twists and opens them. I move a hand down to between us and grab ahold of his hard cock. He moans as I begin to pump him. I match his fingers movements with my own and we are both moaning almost uncontrollably.
"I'm ready." I breath into his ear.
"Are you sure?" I just nod and grab the bottle of lotion.
I squeeze it into my hand and and then drop the bottle back onto the seat. I grab his erection and give it a few pumps to get it completely covered. I lift myself and move his cock into position underneath me. When I feel it against my entrance I slowly move down. My eyes squeeze shut as I lower myself more.
I breath in and out and lower myself the rest of the way.
"Dean it's so tight are you sure this is okay." Cass asks quietly.
All I can do is nod. I begin to rock slowly back and forth. One of his hands finds my waist while the other goes behind my head and pulls it to his. Our tongues intertwine and I slowly begin to slide him out of me. As I slide back down a moan escapes me. Blue eyes stare into mine and before long lips are my neck again biting and sucking. I slide more of him out of me and I move back down quicker this time. I start to set up a rhythm up, down, sideways, back and forth. Before I know it both of us are moaning pretty loudly and I'm slamming his dick into me hard.
Cass places a hand on my chest and pushes me to lean back a bit so he can bite my nipple. As I empale myself with his penis again the new position causes it to hit my prostate and sends a wave of ecstasy through me. I feel my ass clench around him and we both moan. The sound that came Cass's throat could have made me come right then. I move and kiss him hard. I pick up the pace and bounce up and down harder. One of his hands moves to my ass and the other slides down to my cock. My hands go to his shoulders and nails dig into his flesh.
"Cass." I moan as his hand pumping my erection matches my thrusts.
My head goes against his shoulder again. And I lean against him as I feel the pressure rise within me. I bite his ear and breath into it slowly.
"Dean I feel..." He Cass trails off as I continue to bite and blow.
"It's okay just let go. I'm almost there too." He releases my erection and moves to fondling my balls pulling them slightly.
As I moan into his ear I feel his cock begin to pulse inside me. I lean in and kiss him deep as I feel his hand return to my shaft and grip me tight. I moan into him as he pumps me hard. I feel the warm liquid shoot out of it covering both of our stomachs. He moans back into me as my ass clenches around him and he shudders with loud moans as his first organ comes over him.
"Damn Cass."I breath as I feel his cock soften within me.
"Dean that was enlightening."
"Enlightening?" I ask moving to get his flaccid penis out of me and then settling back onto his lap.
"Yes to understand how a sexual interaction can connect people. It was wonderful."
I just smile at him. I had forgotten for a moment who he was and that he had never done this before. I kiss him again this time not looking for anything but the connection we had just built. He moves a hand and strokes my face.
"I don't think we should tell anyone." he says quietly.
I just sit there on his lap feeling crushed. I probably wouldn't have told anyone but the fact that he doesn't want anyone to know was shocking. To know that he didn't want anyone to know he had sex with me hurt. Maybe I had imagined the connection to try and fill a void.
"You can tell Sam if you want." Cass says suddenly like he is reading my mind.
"No I won't tell anyone." I whisper.
"You can tell people it's just..."
"Just what?"
"I'm already extremely impartial when it comes to you and that was before this. "
"I understand"
"Thank you."
"For understanding?"
"No for this. For what just happened. For letting me in."
I just chuckle a little quietly at the innuendo. He just smiles at me.
"I did not mean it like that."
I just lean in and kiss him lightly.
"Can your angel mojo clean and dress us?" I ask.
He barely blinked and we were clothed. I lifted my shirt and found no evidence of my cum on us and I can't feel his inside. I place a hand on his cheek and I use my thumb to trace his lips before I move to kiss them lightly again.
"Thank you." I whisper in his ear.
"For what?"
"For making me feel alive again."
