A/N: This is based on a tumblr promt from fireintheimpala, love that girl.. anyway..I want you guys to know it's not all gonna be phone sex but this one is.. so if that's not your thing you should probably turn back..I'm not sure how far I'm going with this but as of right now I've got at least 3 calls in the making.

Dean wasn't sure exactly why it started, only that it did and he wasn't regretting it at all. The beep notifying him of a text, the late night quiet blast of the chorus of "Angel's" by 69 Eyes, or the voice messages he replayed from time to time. Basically anything that caused his phone to vibrate brought an immediate smile to his face unless Sam was in the room, and even then it was like fighting a damn demon inside, to which he usually failed.

He'd been talking to his messenger of "God" on the phone for quite some time now, it wasn't an unfamiliar thing but what had developed over the past few months was certainly very different. If he had to pinpoint an exact call, he'd have to say it was the night he left Cas at the Gas-N-Sip while he drove back to the bunker. He'd never tell Sam this, but he even stopped off at an all night Wal-mart and bought a headset for his phone so he didn't have to hold onto talked almost the entire drive back, well except for the six hours Dean spent eating, grabbing a hotel room, and catnapping for four and a half hours.

It was nearly a days drive after you counted in the necessary stops, so he'd spent a good portion of the last twenty hours or so on the phone with Cas and his perspective had gradually grown more positive. He was humming along with the radio between calls and quickly realized his face was a little sore from smiling and laughing. It wasn't anything specific really, they just talked. It was light, it was friendly, it was incredibly hilarious when the fallen Angel didn't understand what he meant most of the time. It left him room to casually flirt, after all that was nearly half of Dean's personality, so he let himself loose. Even if Castiel had understood, it wasn't like he was gonna get called out on it.

It was a few days later when he'd gotten caught up on his sleep that things really progressed. It started as a joke, and quite frankly he'd never been so happy that Cas didn't have much of a sense of humor. He picked up the phone from his nightstand when he'd settled into bed and hit the green button twice, automatically calling the last dialed number. The huskiness of Castiel's voice threw him off guard for a moment but he quickly recovered.

"Hey there buddy. If you're gonna be breathing heavy on me. I might have to start charging you." he teased.

"Hello Dean." Cas said in a little calmer tone. He always answered that way, no matter how many times he called the Angel always said the same thing, and it triggered something inside the hunter that caused an instantaneous smile, and a rapid increase of his heartbeat.

"Hey Cas, you okay over there?"

"Yes Dean I'm fine, if my erratic breathing is bothersome I can call you back in a few moments."

"Nah it's okay man, just wasn't expecting you to go all $2.99 per minute on me." Dean chuckled nervously, but if he were the honest type of guy he had to admit that Castiel's raspy pants were hot despite the fact that he was actively trying not to get himself worked up.

"2.99 per minute? what's that?"

"That's what Phone Sex Operators charge Cas, well normally about that.. or that's what the ads on late night infomercials always say. I wouldn't know never tried that kind of thing.. well not the paid version anyway. There was this one girl I met online, called herself fire.. man was she hot! That voice was well worth the three bucks per minute, I was just lucky she wasn't doing it professionally."

Dean stretched his body out putting one arm behind his head and hoped it would keep his hand distracted enough to not reach down and palm himself through the thin cotton that was now covering his half hard cock.

"So what you're saying is that you engaged in verbal intercorse, and that some woman named fire was responsible for your climax, over the phone?"

Dean's mind started drawing webs of information together and something was missing. He assumed that Cas had ran to the phone, or had been exerting himself in some way before answering, but the raspy breathing hadn't stopped. In fact it was growing far more intense by the moment.

"Well..umm that's not exactly how I'd say it, but I guess that's the big picture. Is this the part where I ask you what you're wearing?" Dean teased, he figured Cas would laugh it off, but he miscalculated quite a bit.

"I'm not wearing anything, clothing would certainly get in the way of what I'm trying to accomplish."

Dean swallowed hard, that was the last thing he expected to hear from the mouth of his Angel. He did everything he could to imagine there was some other reason Castiel would need to be naked and breathing heavy. He started by thinking of reasons people get naked, well there's sex and he could count that out…even Cas knew better than to answer the phone during sex. There's taking a shower, but Dean didn't hear any water running or splashing, so that marks off bathing and swimming as well. It was a short list of reasons why people get naked and masturbation was climbing the ladder quickly.

He tried to convince himself that he should just escape the call altogether, tell Cas something came up, that thought caused him to laugh because it technically wasn't a lie. He didn't think the man realized what he was doing, or that you weren't just supposed to answer the phone while you're masturbating unless there's someone you're dating or interested in on the other end of it. That's the moment it hit him, he was actually interested in Cas. Probably had been for longer than he'd admit, but the wanting him…physically was a more recent revelation.

"Uhm, Cas...What exactly are you trying to do?" Dean tried not to sound off, but he couldn't help the gruff sound in his own voice.

"I'm trying to get rid of this damn erection, the thing is taunting me Dean!" Castiel actually sounded desperate. That almost stirred a chuckle out of him, but no one deserved to be laughed at in that condition.

"It's taunting you? How is your boner taunting you Cas?" Dean asked trying not to sound like a weirdo but he felt the embarrassment rise up to his face anyway.

"All the time now, it was one thing to experience this as an Angel.. I could..well not to be crude but I could just make it go away with a simple thought. Now that I'm human, it's like I have no control over it. Every morning it harasses me, sometimes at night, once in the middle of my work day. I can't make it stop, how do you deal with this constant distraction!"

"Cas you do know how to masturbate don't you? I mean that's not something I'm gonna have to friggin teach you right?" Dean tried not to let his voice crack, and luckily he managed that task, but hearing his friend talk about being in a constant state of arousal, fueled his own cock to start throbbing.

"Yes Dean, I'm aware of what masturbation is, hence the heavy breathing.. but even achieving orgasm only keeps it from bothering me temporarily. Usually by the next morning its begging for attention again, and I've tried resisting it, that effort was futile."

"So close you almost had a Trek reference, and buddy there's no end to the madness but if you um.. you know in the morning you can usually keep it down for an eight or ten hour work day, but you'll probably have to do it again that evening." Now there was no denying it, he was rock hard thinking about Cas stroking his cock, and he was losing his battle to not touch himself too.

"But it takes so long, How much of your schedule is devoted to masturbation, because as of right now I think it would qualify as a part time job for me."

"Holy shit CAS! How long does it take you to get off?"

"Currently it's been over thirty minutes, and usually at least that sometimes double."

"How in hell's name do you masturbate for an hour, two or three times a day? Don't you watch porn or something, use some damn lotion, I don't care but it sure as hell should not take you an hour to get off."

"Do you still have the number for that fire girl, cause I'm willing to try anything at this point."

"Uh, no Cas.. umm but .. uh ..ah shit..If you want.. I mean I could .. you know.. help you or something.. If you need it.."

"Dean please tell me if I'm misunderstanding this, but are you offering to help me achieve orgasm over the phone?"

"Don't say it like that Cas, I'm just offering help, you obviously need it… and if you agree, or don't agree, this information never makes it back to Sammy. We clear?"

Dean stopped palming himself long enough to speak his brother's name, because it would be weird if he didn't. He could hear the wheels in Castiel's little Angel brain turning, asking himself if it was the right decision or not. Hell even Dean didn't know if it was a good idea, but he found it impossible not to offer.

"YES! Please Dean, just make it go away." Cas was at the point of begging apparently, and the hunter couldn't help but smile at the urgency in his voice.

"Well look, that's your first problem man.. you can't look at it like it's some sort of curse, the more you enjoy it the easier it will be to finish. If you're rejecting it your body is getting mixed signals, and that's one of the main reasons you're having so many problems with it. Just calm down a little and think about something or someone that turns you on or at least something that makes you happy. " Dean's hand brushed over the thick outline under his boxers and he had to bite his lip to hold back the moan that was begging to be let out.

"Oh, okay.. I can do that, then what do I do?"

"Try spitting on your hand, the wetness makes it feel better, it makes it more enjoyable." Dean was doing his best to stay stoic as far as Cas was concerned but he was beginning to run a little short on oxygen as well, and he knew he wouldn't be able to hide his own arousal much longer.

Dean heard the sound of his angel dampening his palm and it shot sparks of heat straight through him, he ground out a moan despite his attempts to do just the tried to hide it in a cough but it just made things more awkward. He only had two choices left, either let loose and enjoy himself or cut the call off completely, and he just couldn't do that to Cas, nor to himself.

"That better?" Dean was hesitant about asking, but other than the occasional hiss of breath and the pants, he wasn't sure how much Cas was getting out of it.

"Much, much better… wait didn't you say lotion? I have some if that helps?" he offered.

"How bout we save that for next time, uhm, why don't you describe to me what you're doing, and maybe I can help with technique." Dean knew it was low, but the blood that was supposed to be effectively pumping to his brain was currently running down instead of up.

"I don't understand.. I mean I'm holding it and moving my hand up and down, thus causing friction and masturbating."

Dean almost laughed and cried simultaneously, that voice of Cas' was driving him fucking nuts… but the angel had no experience in dirty talk of any kind and it made things unpolished at best. He slipped his boxers over his hips and lifted his ass off the bed to pull them off completely, his flushed cock bouncing back tightly against his stomach.

"Okay listen up we're gonna have to work on how you think things, and say things when you're jacking off. I know you're not the same stiff robot I met in that barn in Illinois. You have one of the largest vocabularies of anyone I know, and while smart is sexy, using words in their base form can be kind of hot too. Instead of copulate or whatever else you would use, just say fuck. You see what I'm saying?" Dean teased himself by just running his fingers over the taut nubs on his chest, trying to stay interested but not wanting to get off too quickly.

"FUCK Dean!" Castiel moaned and for a second Dean could have easily mistaken him for a damn professional.

Cas saying his name was clearly too much for his overcharged erection, precum began to leak from the head and he knew that if he touched himself at all, he'd be lost. The slick white gloss covered the tip and trickled onto his stomach. He decided it was now or never, just jump feet first into whatever the hell this was gonna be.

"Mmm that's it baby, I want you to watch your hand stroking your cock, see the smooth slide of it. I bet it looks nice like that, all hard and flushed and begging to cum. Squeeze the tip, and concentrate on the pleasure you're feeling, and mmmm yeah.. and tell me how good it is. I want to hear how pulling on it makes you feel, what you're thinking about when you do it."

"I thought you only used the word baby when talking about the Impala."

Dean could practically see the head tilt, and fuck if that didn't just rev things up even more. Damn angel had him gone seven ways to Sunday if he found the dorky quirk hot.

"Usually yeah, but when you're being intimate with someone, sometimes pet names are fine.. things like baby, honey, sexy, darlin', and sweetheart. I mean.. if you don't want me to.."

"No! No no it's fine..actually it was..I mean.. uhm"

"What is it Cas? You can tell me."

"I wouldn't have expected it, but the term was quite arousing. I mean.. it was hot, it was really really hot."

He smiled as Cas attempted to take his advice and use more basic words, but he had to admit that there was something off about the way they left the Angel's mouth. Dean wasn't going to last much longer and he was not a fan of cumming first in any scenario, he was a gentleman first and foremost, despite what most people probably thought.

"Okay we're at the listen and learn part of the lesson, I'm just gonna start saying stuff, and you tell me what works for you by giving a moan, saying yes, or just saying my name okay?"

"Yes Dean, that's a good idea."

"Fuck Cas, so hard right now thinking about you stroking your cock . Did you know I was touching myself, I couldn't help it. I tried not to at first, I just wanted to focus on helping you, but damn that sex voice of your's Angel, it drives me fucking crazy."

Castiel had already moaned a couple times, so Dean knew he was on the right track but he wanted to give Cas a second to properly respond so he paused.

"Damnit Dean, this is so much better, so much more intense than it's ever been before, don't stop.. please don't stop."

He can hear the pants growing quicker, Castiel far more excited now than he had been when their conversation started. Dean let himself reach down now, he could hear the urgency it wouldn't be long before he heard the sound of his Angel cum.

"Mmm that's it sexy, I'll make it good for you just keep stroking that cock for me, I wanna hear you cum Cas, I want you to scream my name as you do it too. Come on baby, lemme hear that fucking scream Castiel."

That's when the sound ripped through his ears, hell if he hadn't been wearing a headset it might have caused some minor hearing damage. Castiel screamed his name just as Dean had asked and it nearly made him shoot immediately. He pumped himself a couple more times thinking about what Cas' face would look like when he came and that was enough to send him over the edge as well.

"FUUUUCK CASSSS!" He moaned into the phone, his body vibrating through the final shocks of his giant fucking orgasm.

Things went quiet very quickly and he wasn't sure what to say, or if he should say all. Dean Winchester was the king of hiding emotion, not so much with expressing it. Luckily for him things had always been easy with Cas, would always be that way with the Angel, perhaps something in that whole profound bond thing.

"Thank you Dean, that was very helpful."

He could feel the happiness radiating through the phone and he couldn't resist the even more blissed out smile creeping up his face. It was nice to get off sure, but making Cas happy was like a drug. The guy had so little good in his life since Dean had known him, it was really nice to feel that he could make it just a little better from time to time.

"Anytime Cas..I mean.. you know.. if you want."

"Did you… enjoy yourself Dean? I don't want you to do this out of obligation to.."

"Just hold it right there buddy, I dunno what's gonna happen now. I sure as hell don't know what it means.. but I promise you this was no obligation.. I .. ah hell man you know .. I care about you and stuff, it was nice.. I really meant the anytime, If it helps you out, well that's just bonus."

"Okay, I'd really like that… I think it might not be such a chore this way."

"Yeah Cas, wouldn't be much of a chore at all."

They hung up their phones about twenty minutes later and Dean fell asleep with the biggest smile he'd had on his face in years. It was more than just a good time, it was the start of something significant for both of them.
