Epilogue: Finally a Part of Your World

Serena-loves-Angst

The wedding ship departs once again, but this time, Dean and all of his friends and family are on board. John has given everyone including himself legs for the wedding. Now, it's time for the ceremony to begin.

Castiel fidgets in his suit, dressed in a black two-piece with a blue cummerbund. He looks over to his side of the guests, and feels nervous prickles form at seeing all of his siblings and parents there. They had waited until Castiel's parents had come back from their trip to the Islands of Heroona and could gather up all of Castiel's siblings. As it so happens to be, Gabriel is Castiel's ancestor. Gabriel had been a seagull for a very long time, and he didn't want to go back to where he came from because he was running from them. So, he ended up forgetting most of his memories of home over time. He never even realized that Castiel was his descendant until he met the King and Queen. And that's the reason why Castiel is nervous: his family. His family is the most diverse, raucous, and painfully protective group of people he knows. He knows that many approve of Dean, but they don't know about where he came from and some of them are suspicious of that. They're going to definitely find out where Dean came from by the time the vows are exchanged. He just hopes that nothing is going to go wrong so he can make it to the end of the night. Oh, the end of the night. Castiel smiles at the thought. Tonight is the night when Dean and Castiel will consummate their love as a married couple.

Balthazar pokes him in the side before he can get too deep into his imagination. "Don't be nervous, Cassie. This is your big day," Balthazar says to him in a whisper. "It even happened like you said it would," he adds.

Castiel looks at him in confusion. "What do you mean?"

"You were hit by lightning when you met Dean." Balthazar says, referring to the flash hurricane that Dean had rescued Castiel from.

Castiel laughs, but before he can reply the musicians start to play.

Down walk the bridesmaids and groomsmen, followed by Sam and Anna, the Best Man and Maid of Honor respectively.

Next comes sweet little Hael in her pretty little blue dress, skipping down, casting tulip petals onto the isle with obvious excitement. With her is brave little Samandriel, shaking a little from the responsibility of being the ring-bearer.

Behind them, John and Dean follow.

Castiel sucks in a breath, blue eyes widening. Dean looks positively stunning; he's wearing the same thing Castiel is except his cummerbund is green like his eyes. Castiel is sure he melts a little at the sight of him, and he can tell that Dean's feeling the same way too by the way he's looking at him.

"I can't believe I'm finally doing this…" John murmurs, voice thick.

Dean glances at him, and he clears his own throat so he doesn't sound as choked up as really is. "Me either," he admits. "It still feels like a dream, honestly."

"As long as you're happy, Dean." John says before taking a breath. "Before… I didn't realize that's what should have been the priority, but I let my prejudices cloud my judgment and I made you responsible for things that you shouldn't have had to be responsible for. I'm sorry for that, Dean."

Dean's eyes get watery against his wishes. "It's okay, Dad… I know that Mom is watching from somewhere, so I'm just glad that you're here. I know I don't say it enough, but I'll say it now: I love you, Dad, and thank you." He says honestly and if John's eyes are suddenly wet neither of them are saying anything about it.

They reach Castiel, and the other Prince reaches a hand towards Dean with a bright smile. Dean can't help but smile back with just as much enthusiasm and takes Castiel's hand, clasping the other ones together when he's up on the stand with him.

This is it…

"Do you, Castiel Novak, take Dean Winchester to be your lawfully wedded husband for now and forever?" Joshua questions. This time, he isn't at all worried.

Castiel nods. "I do."

"And do you, Dean Winchester, take Castiel Novak to be your lawfully wedded husband for now and forever?" Joshua then turns to Dean.

Dean nods as well. "God, yes."

There's light laughter in the guests seating and Dean smiles sheepishly at Castiel when he raises his eyebrow at him.

"You may exchange your vows," Joshua allows.

"I didn't know what love was until I met you, Dean." Castiel starts honestly. "I spent all of my time looking for someone, knowing that when I saw him I would know. And when I saw you, I did know. I was just an idiot for dismissing it when I realized you couldn't talk. Though, the more time I spent with you, the more it felt as if I was falling in love for a second time. I was scared; I didn't want to let go of the fantasy of the perfect man that I had in my head, the one that rescued me. But when Balthazar talked some sense into me, I realized that I had something better than a fantasy; I had you. True, you were my rescuer, but I would've taken you as you were then." Castiel squeezes Dean's hands. "When you got your voice back and I realized that you were the one, I swore to myself that I would never let you go, and I stand by that. Dean Winchester, I love you for now and forever, and I will never let you go no matter what." He finishes.

Dean laughs shakily, and he wipes his eyes. "See that, Cas? You're turning me into a chick here, man." There's some more laughter from the assembled and some fond eye rolls. "I don't know how I can top that but here I go." He takes a deep breath. "Ever since I was little I was interested in humans. Dad didn't like that so much," he says with a wry smile, "but he could never stop me from going to the surface or old shipwrecks and just collecting things that I found. I kept them all in this special cove, right? Well, Bobby found it, and while he was in the middle of chewing me out, your ship passed by overhead. I swam up, and I saw you for the first time. I didn't even know that someone could fall that quickly, but there I was: watching you play your flute and thinking you were some kind of god come down to have a fun time with humans." Castiel smiles at him in amusement and Dean grins. "That storm happened, and even though Bobby told me to go back, I saw you drowning and I couldn't let you die, especially not when I could help you. So, I swum you to shore, and I sung to you for a little while, which is apparently my only redeeming quality since you couldn't remember my pretty face." Dean huffs and the guests laugh again. "I couldn't stop thinking about you and eventually one thing led to another and I ended up making a deal with Crowley," he shudders. "The only thing I regret about that deal is that people got hurt, but in the end we all came out okay and look! We're getting married right now, so I have to say that's a win in my book." Dean looks Castiel straight in the eye. "Cas, I mean it, I would go through anything if it meant that I could be standing here with you like this right now. And you better damn well not let me go because it took too much to get here from both our parts." Now Dean is giving me too much credit, Castiel thinks, but lets it go. "I love you so much that sometimes it hurts, but a good kind of hurt, you know? So, I'm not letting you go either." He ends it there, before he starts to ramble.

"You may now present each other with the rings," Joshua nods.

Sam takes the rings from Samandriel, giving him a smile and ruffling his hair, before bringing the rings to the couple. Castiel takes Dean's hand, slipping the silver band with green engravings onto his ring finger. Dean does the same with Castiel's, which is the same except it has blue engravings.

"You may now kiss each other," Joshua says.

Dean grabs Castiel by the hair and crushes their lips together. Castiel places his hands on Dean's waist, leaning into the kiss.

"I love you so much," they say at the same time, blinking before bursting into laughter.

A little while after the receptions starts all of the Winchester siblings and Sam and Gabriel kidnap Castiel.

"If you dare hurt our brother, they will never find your body." Adam says with crossed arms, glaring at Castiel.

Castiel frowns. "I won't hurt him," he promises.

"He nearly lost his soul and freedom to Crowley, so you better treat him right." Charlie and Becky say, looking adorably ruffled.

Castiel shakes his head. "I already made the mistake of not recognizing him from the start, but I'm doing everything I can to make sure that it's fixed and forgotten."

"The only one allowed to mess with our brother is us, so don't even think about making him unhappy." Bela narrows her eyes at him.

"I can do my best to prevent his unhappiness, but when he does become upset, I'll be there to make it better." Castiel nods.

"I will shove my fist so far down your throat and rip your balls outta your mouth if I even think that Dean is unhappy," Jo says with a sweet smile.

"Noted." Castiel says dryly, but he knows Jo will certainly try if she even thinks that she has probable cause.

"I kind of wanted to strangle you," Sam admits. "Because what were you thinking? Marrying Crowley when you'd had Dean?" Sam shakes his head. "Once I knew you were under a spell I let it go, and unlike these guys, I approve of you. Only because Dean went through so much for you, and I can tell you're a good guy. So, just make sure that you treat him right is all." Sam says and Castiel nods, relieved he has at least one person on his side. "Though, on the off-chance that Dean does get hurt: they'll find you in pieces if I'm feeling nice." Even though he says this casually, Castiel doesn't doubt he'll do it.

Deciding that he's not going to let them push him around anymore he speaks up. "I know you're worried about Dean, but you have to realize that this isn't only about him. This is about the both of us and the love that we share. He chose me, and he went through hell for it. Please respect that. We both almost lost our lives for each other, but we still came out okay and together and that accounts for something. I know that at some point I will end up hurting Dean somehow, and he'll end up hurting me. It's what people do, but when people in love hurt each other, it's their job to get past it and fix their wrongs." Castiel says, and he looks everyone in the eye. "I love Dean, and I will not let him go or back off because of a few threats." He states firmly.

Slowly, they all smile at him, and Castiel realizes what just transpired. They were all testing him and he passed with flying colors.

"Looks like my descendent inherited some balls," Gabriel chuckles.

"What he means is," Lisa starts with a smile, "welcome to the family, Castiel."

Castiel laughs when Dean venomously threatens the guests who are trying to convince Castiel to get on with it and go "consummate" their marriage. Deciding to take them up on it, and wanting to make love to the man he's sworn to be with for the rest of their lives now and hereafter, he picks Dean up bridal style. Dean yelps, not expecting the sudden action, and points warningly at all of the laughing guests with his best glower. His actions aren't very effective because of the blush going all the way from his cheeks to the tips of his ears.

"Let them laugh. After all, you and I will be doing something much more fun." Castiel murmurs in Dean's ear as he carries him into the ship's cabin and down to their room.

Dean's blush becomes more pronounced and he mutters, "Son of a bitch…" under his breath, making Castiel laugh.

"So, how does sex work for merpeople anyway?" Castiel questions as he kicks the door open and then closed once inside.

"We grow a pair of legs," Dean shrugs. "After a few minutes of tail twisting and getting the arousal hormones to the point of where we want them, our tails split into legs and we get human anatomy and all. It only lasts as long as the hormones are in your system though," he explains.

"So when Crowley gave you that potion, do you think he put that hormone in there?" Castiel asks, curious.

Dean shudders. "Probably, and he most likely put some stabilizers in there too, to balance out the arousal and making sure that it lasted three days and other things like that." When he sees Castiel stare at him in surprise he flushes. "What? I like potions. Not the kinds Crowley worked with, but the ones that you can use for everyday purposes or for healing or stuff like that." He says.

"A prince and a chemist, not something you hear about often." Castiel teases, leaning in to kiss Dean's nose.

"Can we stop talking and move onto the sex that makes honeymoons so great?" Dean complains.

Castiel laughs, walking forward and depositing Dean on the bed. Wasting no time Dean grabs Castiel's collar and pulls him down for a heated kiss, parting his lips and letting Castiel in. He moans when Castiel rubs his tongue against his and then lightly trails it against the roof of his mouth. The hand that was carding through Castiel's hair grabs Castiel's arm and he flips them over so he's on top and he takes control of their kiss, running his hands down Castiel's chest.

"Too many clothes, Cas." Dean scolds with a soft growl before pressing his lips against Castiel's jaw and lightly grazing his teeth against the stubbly skin.

"Then, take them off." Castiel retorts, grabbing Dean's head and bringing him back up for a fierce kiss. Dean obliges and unbuttons Castiel's shirt and pulls his pants and boxers down. He leans down and kisses his way down Castiel's body, dipping his tongue into the other's navel teasingly before reaching Castiel's erect cock. He licks the head experimentally, decides he doesn't mind the taste, not all that different from the other mermen he's given blowjobs to in his quite insane early twenties, and slips as much as he can into his mouth. He hollows his cheeks and sucks, running his tongue up and down the hot, pulsing flesh. However, since he can't take all of Castiel in his mouth he starts stroking the base with his hand. He smiles around Castiel's cock when he lets out a groan and slides his fingers into Dean's hair.

"God, Dean! Where the fuck, ngh, did you learn how to do that?" Castiel moans. Dean looks up at Castiel through lowered lashes and winks. The sight of Dean's plush pink lips wrapped around his cock and the way he's stroking is too erotic for words and Castiel is worried he'll come before he's inside Dean. "Dean, Dean! Stop!" He pushes Dean away.

Dean immediately stops and pulls away, looking worried. "What? Did I do it wrong?" He asks, biting his lip. Why did something go wrong this time? Is there something different about human anatomy than a merman's?

"No, Dean, you did it too well." Castiel chuckles. "I just didn't want to come before I was inside you," he says and Dean's face reddens.

"Oh, right…" He says and bites his lip again, ducking his head a little. How can he tell Castiel that this isn't his first time? That he's only so nervous because it's so surreal to have the man he loves actually want him like he does?

Castiel's face softens and he places a hand on Dean's cheek, lifting his face up and watching with rapture as Dean's eyes flutter at the gesture.

"I know you haven't done this before, so we'll take it slow, okay?" Castiel murmurs, pulling Dean to him and kissing him.

"Uh, Cas, it's not that I, uh," Dean bites his lip again.

Castiel's eyes gain understanding and he leans back, taking his hand away. He watches Dean tense up, probably expecting a rebuke or something of the like.

"Okay, well, this isn't mine either. So, that's okay. Why don't you tell me what's really making you nervous?" Castiel questions softly, not angry with Dean. Maybe a little disappointed he couldn't be his first, but he should've realized it by the way Dean gave him that amazing blowjob.

Dean looks at Castiel and he sees that he isn't mad or disgusted. He feels relief but shrugs outwardly. "It's just… Well, it doesn't feel like it's reality. You wanting me like this." He rubs the back of his neck. "I dreamed about you every night since I rescued you, and every time single time I would wake up when we were done and just wallowing in something warm and sickeningly sweet that probably every one of my sisters dream of. It was worse than if I had woken up in the middle of getting it on, because then I wouldn't have gotten to know what it feels like to want someone for more than sex."

At this Castiel pounces on Dean and kisses him furiously. Dean melts under his touch and he eagerly reciprocates the action.

"You," Castiel divests Dean of his shirt, "are such," he trails his lips to Dean's neck, "a perfect," pressing against the other's rapid pulse point, "idiot." He moves to the side of his neck and bites down, suckling and marking the other's flesh. "I swear, how does someone like you exist?" Dean moans and Castiel licks the mark before moving down to Dean's chest, lips covering one of Dean's nipples and getting an arched back and a long drawn out moan from the man under him. Castiel grins around Dean's nipple, and as he slides Dean's pants off. "This right here," he palms Dean's erection, "is real and you are awake and you have me. I will not vanish after this is all over. We will live the rest of our lives out together and no matter how much you might want to, you won't be able to get rid of me."

Dean lets out a little sob and he nods. "Okay, Cas. But I swear, if you don't keep that damn vow you just made, I will let my family loose on you." He threatens.

Castiel twitches, remembering the threats. "Note taken," he says dryly before leaning down and kissing Dean, making both of them laugh. Castiel dips his fingers into the small bowl of oil by the bedside table, deciding that he wants to make Dean make lots of noise. Now that the other has his voice back, they can put it to good use.

"Glad we got that over with then, now get on with it." Dean demands, growing impatient.

"The things I am going to do to you, Dean…" Castiel growls against the other's skin, nipping the flesh of Dean's pecs. "You're going to be moaning, crying, mewling, whimpering, and begging for me all night long…" He promises and Dean can't help the turned-on whimper he lets out at imagining what Castiel will do to get Dean to make those noises.

"Okay, Cas… I'm down with that," Dean says breathlessly as Castiel puts his lubed fingers to Dean's entrance. He stiffens against his will, but when Castiel strokes his cock loosely and starts mouthing at his jaw he relaxes and Castiel slips a finger inside, rubbing gently against his walls. Dean moans at the sensation.

"This okay, or is it getting too uncomfortable?" Castiel's breath is warm and puffed against Dean's skin as he adds a second finger to join the first and starts to scissor around inside Dean. He reaches in deep and crooks his fingers, finding a small bump in Dean that makes him let out a scream and arch off the bed.

"Cas," Dean pants, "if you fucking stop I will kill you!" He snarls but it melts into a strangled moan turned mewl when Cas drags his fingers across his prostate once more and adds another finger.

"Whatever you want, princess." Castiel teases and kisses Dean.

"I'm only letting, ung, that go because you have your fingers shoved deep up my ass and I like the way they―God, Cas!" Dean snorts and the end of his sentence gives way into a drawn out moan when Castiel crooks his fingers in just the right way again.

"What was that?" Castiel chuckles.

Dean's eyes are screwed shut and he's fisting the sheets in a white-knuckled grip. "Cas, if you don't get you're cock in me within the next second I will kick you off this fucking bed!" He growls.

Castiel pulls his fingers out, making Dean whimper at the loss. Castiel rubs some oil onto his cock before lining up at Dean's entrance, and he looks at Dean again. "Are you sure you're ready, Dean?"

Dean pulls him in for a kiss that leaves them both breathless. "I wasn't kidding about kicking you off the bed, Cas." Dean pants against his lips when they pull away.

Castiel's lips curve up into a grin and he laughs before slowly pushing into Dean, and the other's hands wrap around him, scrabbling to find an outlet at the feeling of being stretched and filled after so long. Castiel groans at Dean's velvety hotness fluttering around him as the blond tries to adjust to Castiel's length.

"God, Caaaaaaaaaaaaaaaaaaas!" Dean groans, voice loud, unrestrained, and musical symphony to Castiel's ears.

"Careful, Dean, you keep that up and the entire ship and your father's kingdom will hear you." Castiel warns jokingly, but his words aren't quite as effective because they're delivered in pants.

"Who the fuck cares?" Dean moans, slowly moving his hips down on Castiel's cock when he's fully adjusted. "If they didn't know we were going to do this then they're all, ngh, idiots!"

"True," Castiel smiles before starting to set a slow, steady pace for the two of them.

"Slow and steady didn't win the race, Cas!" Dean growls, rocking his hips down faster to make his point and he throws his head back when the head of Castiel's cock brushes against his prostate. "There, Cas!" He pleads and Castiel shifts his angle so that when he thrusts in deep he'll slam against Dean's prostate.

"That, hah, any good?" Castiel asks breathily as he keeps himself upright by planting his hands by Dean's head.

At this point Dean's devolved into hoarse and unintelligible whimpers and moans, and Castiel has never heard anything sweeter. He watches in reverence as Dean's eyes flutter in pleasure and the blush that's staining his cheeks shine because of the sweat forming on his body. Castiel growls when Dean bites his lip to try and stifle some of his moans.

"Didn't I tell you I was going to make you scream, Dean?" Castiel questions lowly as he bites down harshly on Dean's neck.

Dean gasps. "Yes!" he groans when Castiel starts suckling at the bite.

"Then why were you biting your lip?" Castiel growls.

"S-Sorry―fucking hell, Cas!―w-won't happen again." Dean pants, trying to shove down his embarrassment at the mewl he'd let out when Castiel thrusted particularly harder against his prostate.

"It better fucking not." Castiel warns, but his words mean nothing because he knows he's getting close, and by the way that Dean's raking his nails down his back he knows the other is too. He grabs Dean's arms and pins them above his head, leaning down to kiss him wetly before leaning back up to just take in the blond underneath him. The way he's just beautifully pliable when struck by ecstasy, spread open beneath Castiel, hands weakly twisting against Castiel's grip and fists tremblingly opening and closing, head arched against the pillow, giving voice to the most divine, filthy groans as Castiel shoves greedily into him. The heat, the clench around him, feels beyond sensation and Castiel wants to weep at the sheer beauty of what he and Dean are sharing.

He lets Dean's wrists go, one keeping himself propped up above Dean and the other grabs Dean's cock and starts stroking to match his thrusts. "Come for me, Dean." He orders.

Dean's breath catches at the low rumble in Castiel's voice and tips his head back even more, arching off the bed as he comes, sticky release covering both their chests and Castiel's hand.

"Cascascascascaaaaass!" Dean cries out.

Castiel's hips stutter as Dean's impossibly hot walls clamp down on him as he orgasms and Castiel releases his own seed deep inside Dean.

"God, Dean! So tight!" Castiel chokes as he rides out his own orgasm before sliding out of Dean, who lets out a small groan. He feels strangely empty and even the cum filling him doesn't make up for the loss of Castiel's cock.

"That," Dean starts, "was the best sex of my life." He informs Castiel. "I love you," he says as seriously as he can.

Castiel laughs, plopping down beside Dean and throwing an arm around Dean's waist. "I love you too," he says, smiling softly.

Dean turns his head and grins at Castiel, green eyes bright with love and laughter and cheeks sweaty and glowing with post-orgasm flush. As Castiel drinks the sight of him in, Dean does the same. He tries to burn the image of Castiel's deep blues that are warm with love, sex-mused hair (I did that, Dean thinks gleefully), and pink lips that are curved in an amused smile.

Dean he pulls Castiel in for a drawn-out kiss. "Why don't you try to break the record?" He suggests with a waggle of his eyebrows.

Castiel laughs and smacks Dean's chest, grabbing a towel off the bedside table when he realizes that Dean's cum is still covering them both. He wipes them off, but leaves Dean's hole untouched, and throws the towel away.

Dean raises an eyebrow. "Cas, you, uh, missed a spot." He points out. Castiel smirks and only lowers his head to Dean's hole and gets to work. Dean's hands fly to Castiel's hair and he moans. "N–Never mind, you got it…" Dean amends breathily and mewls when Castiel's chuckle reverberates throughout his entire lower body and his cock stirs and gets half-hard again. "If you dare stop until I say so, you are a dead man, Cas." Dean warns.

"Aye, aye, captain." Castiel replies before continuing his licking and probing.

"Cassssssssssss," Dean moans.

Gabriel whistles when he hears Dean cry out from the cabin. "Looks like ol' Cassie-boy is riding Dean hard," he snickers. "Why don't you and I go make some noise of our own, eh Sammy?" He waggles his eyebrows at Sam.

Sam rolls his eyes. "If you really think we'll be louder than the newly-weds, you need your head checked, Gabe."

Gabriel only grabs his wrist and pulls him to the cabin. "Doesn't mean we can't try," he says and Sam laughs, letting Gabriel drag him away.

Now we can walk,

Now we can run,

Now we can stay all day in the sun.

Just you and me,

And I can be,

Part of your world.

THE END

Oh god it's really over isn't it *cries* I really loved writing this story, and I'm so pleased with everyone who supported me this far and even though it's the end of this story, it is definitely not the last you guys will hear of me. I hope you come back and read my future Destiels to come and keep your fingers crossed for the sequel, which will be about Cas, Dean, and their daughter: Mary-Annael "Mary" Winchester-Novak. I know she sounds like a Mary-Sue, but I'll do my best to ensure that she's original, and considering I picture her having Melody's personality (from the TLM sequel if you recall her), it won't be too hard :) She will be their biological daughter since Mermen can get pregnant (if seahorses can do it so can Mermen!) and I will have a little drabble series about Dean's pregnancy, one chapter for every month of the pregnancy probably. Thank you once again for sticking by this fanfic!
