Heat was a hit. It was sexy and interesting. You all ate it up and many wanted a sequel, which I had been considering ever since the end. I wanted to wrap up the Sabriel better and divulge a bit, but at the same time I thought I've been dying to take a crack at Destiel mpreg. Then it hit me: Heat has the perfect plot to fit it in there and still actually make some logic! Thus Heat II was…heheh…conceived.
So the sequel takes place in a magical, semi-canonical world where Sam, Dean and Cas managed to bypass all of the tablet crap but still live in the Men of Letter's bunker. They're hunters and they still live an isolated, lonely life by themselves but it's not as fucking devastating as the canon show. This way it's also possible to have a family.
Anyway, just wanted to get you up to speed on everything. This is not my first mpreg fic ever, but my first Supernatural mpreg. Enjoy!

"It has been noted that true love, when absorbed by the celestial being, will set a chain reaction called angel season. Every fifth year starting the day that the angel met its true love, season runs for a month or two. During this time does the vessel communicate with the true form of the angel and open itself for true conception."

-The Care and Keeping of Nephilim

"Yeah, yeah, that's exactly what I thought. I mean, she seemed pretty certain. What do you think?"

"Tomorrow."

"Night?"

"Yep."

"So actually tonight?"

"Yeah you know what I mean."

"Alright." Sam looks down at the clock on his laptop. "Almost 3. Maybe we should try to get some sleep."

"I guess," Dean groans. He's slouching in a chair around the table, staring at the ceiling while Sam keeps looking at him.

"What's wrong with you lately, Dean?" Sam asks. He thinks it sounds hacky and stupid since he's noticed Dean's off behavior for a little while now. They moved into the Men of Letters' bunker two months ago and at first Dean was happy; he had a safe place to live with his brother and be with his lover. He had a room and a proper kitchen. They had endless rooms to set up and continue their paranormal research.

"Don't know," Dean says quickly.

"We finally have a place to settle into. Isn't this what you always wanted?"

"I guess so," says Dean. He clicks his tongue once but continues to watch the high ceiling of the bunker. "But that's the thing; we've lived our whole lives running between places. Just feels weird to actually have place. A home. A room." Then Dean closes his eyes and mutters, "a partner."

"But that's good," Sam adds. "Being happy is good. Right?"

"Something's missing."

Without saying anything else, Dean gets up from the chair quickly and walks off towards his room. Sam rolls his eyes. What else can he say? He hates to see Dean having trouble but there's nothing he can do about it. His computer remains on for another hour but then he crawls to bed for some well-deserved and appreciated sleep.

Dean on the other hand goes to his room with a sour face. He really hasn't been feeling right and that alone bothers him; Dean's mood will affect Cas', but apparently not too detrimentally.

As soon as Dean comes into his room, he finds Cas standing by the bed, smoothing down the covers. He's been making it for a while now, trying to have it perfect for Dean.

"Hey," Dean says as soon as he walks in. "That's fine, you don't have to keep doing it."

"Are you sure?" Cas asks. His palms run across the blanket a few times.

"Yeah." Dean steps up behind Cas and wraps his arms around his waist, pulling him close and giving the angel a couple kisses on the neck. "You know you can always hang out with us when we're researching."

"I know," Cas says. He closes his eyes momentarily and leans his head back, enjoying the kisses from his partner with a small sigh. "But I've been working in here. I think I can be the most help if I stay here."

"If you're sure, babe."

"I'm sure. Thank you."

Dean holds Cas a bit longer, resting his chin on his shoulder and leaning against him. He stares at the wall and Cas takes a deep breath. "Are you feeling unwell, Dean?"

"I'm fine," says Dean. But he thinks for a moment in silence then adds, "You doing okay?"

"Yes. This bunker is very comfortable, very orderly. I enjoy having a place of my own and more importantly a place that we can share. Sam is happier as well. It brings me great joy to know that the people I care about the most are content."

"Good," Dean says with a smirk. He hugs Cas tighter and this makes the angel wonder.

"Are you positive that you feel 'fine'?"

"Mmhm."

"Dean?"

Cas turns around within Dean's embrace and faces him. The angel tilts his head and stares into Dean's eyes with his own looking large, deep and sad. Dean wets his lips and glances down.

"Dunno," Dean mutters.

"What?"

With a reluctant sigh, Dean lets go of Cas and walks around to the other side of the bed. He steps out of his pants and pulls off his shirt. "Been a little down, I guess," he admits.

"Down?" Cas asks, staring at his partner in confusion. "Down from where?"

"Sam's noticed it, too," Dean continues. He peels back the sheets and gets beneath them, patting the space beside him as a lazy signal for Cas to join. "I'm not as happy as I should be here, but I dunno why."

"I see," says Cas. He removes all of his clothes, since he thinks that's what he is supposed to do, and joins Dean in the bed. Dean turns the lamp on the nightstand off and hugs Cas' back up against his chest. The embrace is tired and weak. "Do you prefer a life on the road?"

"No, definitely not," Dean says with a slight shaking of his head. "I mean that's all I know, but I don't like it. I've learned to adapt and accept it but I'd stay here any day. Shit, I'd love to have a life where I don't hunt but that's not gonna happen."

"What can I do to help you?" Cas asks. His fingers entwine with Dean's hands that are touching Cas' chest lazily.

"Nothing. But thanks, baby. I can always count on you."

Another kiss goes onto Cas' neck and Dean settles for sleep. Their embrace is warm and inviting, but of course Cas doesn't need to rest. Life in the bunker has allowed him to develop a routine that includes staying in bed with Dean while he sleeps. This gives him plenty of time to watch him and mull over the events of the day.

"Dean…"

Cas stares at the sleeping man. Occasionally he extends a couple fingers to caress Dean's face, touch his skin just for the satisfaction of feeling him and allow his nerve endings to flare up with the heat between them.

But morning rolls around and even though there is no alarm, Cas sees the clock shows 7am. That's enough time for Dean to sleep.

"Dean…"

The angel cups his hand around Dean's shoulder and gently shakes him. Dean's face fidgets, twitches, takes in a deep breath that quivers slightly but he remains asleep. Cas focuses on him and tries to give him extra time, but something warms grows inside and he shakes Dean more.

"Hhnnnn…"

"Dean."

"Whuhh…huh…Cas…"

"Dean."

Cas leans in and puts his lips right onto Dean's. His kiss is surprisingly intense and it makes Dean open his eyes real wide, but a smile curves anyway. He breaks the kiss and keeps their noses touching. "Well good morning to you too, Cas."

"Good morning, Dean," Cas mutters, his lips hungry for more. He stares at Dean lovingly but also with a flicker of fire burning inside. He pushes Dean onto his back and straddles him, going in for another kiss that is partnered with soft moans.

"Oooh," Dean groans, immediately running his warm palms down Cas' back and gripping his rear. They begin to grind together. "Love it when you're horny in the morning."

"Dean," is all Cas responds with, eyes fixed hypnotically so on his partner. He has a solid erection the rubs against Dean's underwear with desperate need for access. "Make love to me."

"Mmm," Dean growls hungrily, rocking his hips to meet Cas' boner with his while he tips his head back, closing his eyes gently. "Good idea."

Dean lets go of Cas momentarily so he can tug his underwear off, unsheathing his now-mighty boner and rubbing it between the angel's cheeks. Cas breathes heavily and leans backwards to grind down on Dean.

"You're so fuckin' horny, Cas," Dean moans with a slight chuckle. He rubs his hands in firm circles around Cas' ass, then dips his fingers in the middle but stops in surprised. "What? You've been masturbating?"

Cas shakes his head. "No."

Dean's fingers rub around Cas' hole, which is oddly moist and stretched out. He's a little conflicted since it feels extremely sexy to him, but he can't figure out why it's like that. Two fingers rub around inside and Cas moans loudly.

"You sure you were rubbing something around in here?" Dean asks, eyes narrow on Cas as he fidgets and wiggles from the feeling.

"I-I'm sure," Cas gasps.

"But you want something now?"

"Please…"

With a big smirk, Dean rocks his hips upwards and pushes his cockhead right inside Cas' hole. The angel is ready and swallows him up immediately with great cries of pleasure, reaching his arms back to grasp onto Dean's legs. Cas is able to work his core hard and ride Dean out.

"Fuuuuuck," Dean groans. He puts his hands onto Cas' hips and holds on while they hump. "So goooood."

"D-Dean," Cas moans through exasperated breaths. "Deaaan!"

"Like when I fuck you?"

"Yes…"

"Like when you get this nice big dick in the morning?"

"Ohh, ohh, yes!" Cas squeals. He tightens his hole around the base of Dean's cock and they both moan louder.

"Been waiting all night for me to wake up and fuck you?"

"Yes!"

"That's gooooood," Dean purrs. His thumbs rub tight circles on Cas' firm waist and he fucks him harder. They fuck each other harder. Cas is working himself up into a frenzy and he's sweating already, rock hard dick bouncing with his humps.

"Dean!" the angel suddenly shouts. He clenches and scratches his nails into the man's legs, yelping in desperation as his orgasm is achieved. Dean delivers hard thrusts deep within Cas, spewing the angel's cum all over Dean's chest and a bit on his face. Then Dean cums, too; he grabs his waist securely and slams one final blow into him, ejaculating profusely.

"Ohh, Dean…Dean…"

Cas is out of breath and collapses onto Dean's chest, sandwiching his cum between them. Dean growls a little and hugs his lover. "You okay, baby?"

"Yes…"

They heave and gasp for a few moments without any words. Cas leans forward enough that Dean slips out of his ass and his cum oozes out on each other. The moment is so tender and lovely that Dean doesn't even care about the mess. But Cas buries his face into the crook of Dean's neck and begins to tremble.

"Cas? What's wrong?" Dean coaxes, rubbing the angel's back slowly.

"I'm not sure," Cas responds with his voice muffled by Dean's flesh. It sounds like he's beginning to cry.

"Cas?" Dean asks again, this time less caring and more alarmed and worried. He tries to pull him off to get a look at him but Cas remains fixed in the nape. "Are you crying?"

"Yes."

"Why? Are you in pain? Did I do something wrong?"

"No."

"Cas. Cas. Talk to me, look at me."

Reluctantly, Cas sits up enough to make eye contact. His face has suddenly become quite blotchy and tears run down his cheeks.

"Cas!" Dean yelps in surprise. He gives the angel many kisses on the lips, so worried and shaking a bit himself now since he really doesn't know how to respond. "Why are you crying?!"

"I'm not feeling well," Cas admits. He gently rolls off of Dean and curls into a ball beneath the covers, holding his fingers to his forehead. "Empty, or so."

"Empty?" Dean turns on his side and rubs Cas' back some more. He's trying to be compassionate but that's not always his strong suit. "I didn't fuck you good enough?"

"No, that was good. Something else is wrong. I'm not sure."

Dean frowns. "Can you explain it any better?"

"You were sad last night," Cas says with an exhausted sigh.

"Well, yeah, but, but nothing serious. I was just kinda moody. It happens. But I'm happy, I'm real happy. I got you and Sam, the bunker…so I get grumpy every now and then."

"You were very sad."

"Even if I was, I'm feeling great now. Except for you being like this. Can I help you at all?"

Cas shakes his head. "Possibly some time alone."

Dean sighs. That was the answer he was afraid of, and now he's certain it's his fault. Either way, he won't deny Cas his request, so he dresses and leaves him alone. Oddly enough, he is feeling very good. All of the sadness and weird emotions from the night before, which had been bottling up for some time now, seem to be gone.
