Thank you for your continued reading! I truly appreciate it. This will likely be the last in the series, but by the time we reach the end maybe I'll feel differently.
As the description says, this story has considerably less smut than the first two, especially the first. I know that it's come a long way from that, since the original Heat was pretty much just a fuck-fest, but the "angel season" proved to be an awesome opportunity to make logical Destiel mpreg. As I wrote Heat II, it occurred to me that I had to make a sequel that showed Mary growing up and following in her father's footsteps of messing shit up. This should be a good ride. As always, feedback is appreciated and often taken into consideration when writing.
Again, my apologies to the folks who read the first Heat and have expected the sequels to be just as, if not more, smutty. Never fear, there will be some sex throughout Heat III.

It's been seven years since Mary was born. Seven years of learning, growing and unfortunately hiding. Cas and Dean have agreed that they don't want her leaving the bunker; if Heaven knew about her she would clearly be on their most wanted list, and if any demon happened to catch wind, well, they aren't even sure what they would or could do with her. So she's been inside and so has Cas. There is an occasional need for him on a hunting trip and Dean will swap Sam for him, but they prefer Cas to be at home anyway because Mary is the closest with him.

Dean has worked very hard to keep Mary from learning to be a hunter. Part of him desperately wants to teach her how to shoot, but he knows that's the wrong thing to do. Having his own kid has given him a lot of reflecting and it's occurred to him that most of what John did was strictly selfish and for his own benefit. Dean doesn't want to be like that. He's constantly reevaluating everything he does now, asking "is this because I want it, or because it's best for them?" But he still struggles. A lot. It's a good thing he has Cas because Cas doesn't struggle with it at all.

They of course have had to teach her about angels and demons, since she clearly isn't a normal human (even if they managed to lie to her and say she was) and eventually she would have to know anyway. Cas plans to teach her how to use her powers defensively, but not until she's older and can fully understand the meaning of pain and death. For now, they have long study sessions where they work on using the angel mojo for good things. She's quite caring, too, and extremely smart. The majority of her day is spent reading; books they bring her and books in the bunker. Her brain is a little machine that constantly receives updates and needs considerable software to keep it running well. Every time that Sam and Dean return home from a hunt, they make sure to bring something new for Mary.

"Father!"

Mary comes bounding down the hall and into Dean's arms, greeting him from their triumphant return after three weeks of being away.

"Hey, baby girl. How you been?" Dean asks, giving her a tight hug.

"Good," she says. "We've made good progress."

"Oh, yeah? Like what? Show me."

He sets her thin frame back on the floor and she starts to look Dean over curiously. "Did you injure yourself?"

"Nah, not really. But Uncle Sammy got scraped up pretty well."

Right on cue, Sam walks in with a paper bag in his hands. Mary sees him and runs to give him a hug, too. "Well hi, Mary. Did you have a good three weeks?"

"Yes," Mary says with a nod as she lets go of her uncle. "I did. And father says you hurt yourself?"

"It's not bad, really," says Sam. He goes to the table and puts the bag on top, then pulls up his sleeve and shows her a couple claw marks in his forearm. "I'm not worried."

"Watch this," Mary says. She takes her first two fingers and sets them on the wound, instantly healing it up.

"He-eey!" Dean cheers. "That's awesome!" He holds her by the shoulders and rubs gently, giving her a kiss on the top of her head. "How'd you learn that?"

"Mother taught me. It took me a while to do it good."

Sam rolls his sleeve down over the clean flesh and smiles. "Thanks. You're doing really well."

"Mmm," Mary nods in agreement. "Did you bring me anything?"

"Of course we did," says Sam. He points to the paper bag. "All yours."

Mary's eyes flash grey for a moment. "Really? Actually?"

"Yep!" Dean adds. "Now where is your mama?"

"In our study room."

"Alright, well how 'bout you stay here in play with Uncle Sammy for a while and I go see mama?"

"That's fine."

Dean walks away and Mary starts looking through the paper bag. She pulls out a couple books and a few craft kits. "We just grabbed a bunch of them in the store," says Sam. Mary carefully sets everything out on the table then looks them over.

"What is this?"

"Dreamcatchers."

Mary picks up a box and looks it over. "What's a dreamcatcher?"

"A Native American object that is used to catch bad dreams. They're pretty well known."

"Oh," Mary says, staring at the back of the box. She flips it over and looks at the front a little while longer. "Does it work?"

Sam shrugs. "Do you have dreams?"

"Yes."

Mary sets the box back on the table and replaces it with a book on hair braiding. Sam smiles sheepishly and says, "You can do something with your hair." Mary pages through the book a little with a curious face. She lets go with one hand and runs her fingers through her hair slowly. It's long enough that she could bring it over her shoulder and work with it.

"But what's the point?" she asks.

"What, of braiding hair?"

"Yes."

"Some people do it for fashion, or to keep their hair out of their face, sometimes just for fun. The basic braid is pretty easy but it looks like there are more complicated techniques explained in the book." Sam leans down and flips a couple of the pages while Mary watches. "French braid, lace braid…heheh, look; angel braid."

"Angel braid?" Mary makes a confused face when she asks.

"It's just what they call it, it has nothing to do with real angels. Most people don't know much about real angels."

"Oh…"

"So do you want to try anything? I think your parents are going to need some alone time."

"Yes," Mary nods. "Sit."

"Um, alright." Sam goes along and sits down at the table. He starts to look at one of the other books while Mary picks up the braiding one and reads part of it. When she's done, she closes it and puts it back on the table then starts to touch Sam's hair. "Hey! What are you doing?"

"I'm going to braid your hair," she says very calmly.

"The point is for you to braid your own."

"I'm going to practice on you first. That should be easier than trying it on myself."

Sam raises his eyebrows. "Oh," he says. "That makes sense." He straightens his back a bit and tells her to go ahead.

She braids his hair with a very serious expression. It's incredible how she only has to look at the book once and the info retains perfectly in her head. She's able to remember what each line in the directions says to the T. She's very gentle, too; Sam just sits there looking at a book about ocean creatures while she does her thing.

"I'm done," Mary finally announces. Sam shakes his head a bit and feels the braid hanging there.

"How's it look?" he asks.

"It looks like a braid."

"Then that's good, right?" Sam smiles and runs his hand over his hair. "You're so much like your mother, it's almost funny."

"He's not very funny though," Mary says, narrowing her eyes.

"I know. That's just an expression. When something is really coincidental we sometimes say 'it's funny' because it's so peculiar and interesting that we feel like laughing about it."

"I see," says Mary. "Um, then, Uncle Sammy, can we make these dreamcatchers together?"

"Yeah of course." Mary smiles and takes the seat next to him. They set to work and make sure to give Dean and Cas plenty of time together. They need it.


"Guess who," Dean says, acting like an asshole and coming up behind Cas, slipping his arms around his waist.

"Hello, Dean."

"You're no fun."

"I know that it's you for a number of reasons."

"I know, I know, but still." Dean pretends to pout then presses his lips to Cas' neck and sucks gently. "Missed you, baby."

"I missed you too, Dean. How was your job?"

"Not bad at all. And you? How've you been?"

"Very well, aside from missing you."

"Mmmm…"

Dean lets his hands roam down the front of Cas' shirt and to his crotch. Cas turns his head back and they kiss slowly. When Dean tickles Cas' semi, the angel pulls out of the kiss with a gasp and says, "Should we go to our room?"

"Yeah, that's smart," Dean growls. They quickly retreat to the bedroom but once the door is shut they go back to kissing. This time Dean grab Cas' face and pulls him close, sucking at slurping at his lips loudly as Cas paws at Dean's shirt. "Get on the bed," Dean says between kisses.

Cas nods and obeys. He lays on his back and pulls Dean on top, but Dean doesn't stay there for long. Once Cas has his head at the pillows, he crawls down between the angel's legs, tugs off his pants and immediately buries his face between his legs. Cas brings his knees up to his chest and gasps hotly, grabbing the covers. Dean's short beard, which he's grown out for his "own reasons" tickles and lightly scratches the skin around Cas' hole, and the angel likes that.

As Dean's gotten older, he's realized there are better things than just taking care of his own sexual needs. Not to say that he didn't care about how Cas felt before, but in time he's learned to put more emphasis in getting Cas off. It hasn't been easy to wake up and see the same, perpetually beautiful 34 year-old man smiling at him, only to go to the mirror and see the aging process slowly creep up on himself. His crow's feet are bigger, his forehead is a little more creased, he's starting to get grey hair and even his stomach has been slightly expanding. He was able to give no fucks before and nothing bad resulted from it, but now his actions have consequences and that really pisses him off.

"Ohh, Dean, Dean!" Cas yelps, wiggling about. His toes curl as Dean's tongue dives inside him, batting around the moist hole he knows so well. He reaches up with one hand and gently jerks Cas off.

"You like that?" Dean asks, taking a minor break from licking to let his tongue relax. He peers up at Cas and sees the angel's twinkling eyes watching him, cheeks flushed, biting his lower lip and breathing heavy. "You gonna cum?"

"Soon," Cas moans.

"Mmmm, alright, we'll get there." Dean growls satisfactorily and dives back down between the sweet cheeks. He runs the width of his tongue over the wet hole and feels it contracting. He jerks the angel's cock faster. Cas cries out in twisted joy as he nears his orgasm. "Shh, baby, shh."

"R-right," Cas yelps. He tries to quiet himself. In general they've become pretty good at keeping their noises at a minimum, since they are absolutely not ready to talk about sex with Mary. She hasn't shown any interest in that sort of thing and they plan to keep it like that. The Care and Keeping of Nephilim, their only handbook on raising a half-angel, ends with a brief paragraph of puberty that simply says it "will come when the Nephilim is ready."

"Oh! Aah!" Cas groans, straining his back and bucking it's Dean's fist. "Haaah!" He convulses and twitches as a thick loud oozes from his cock. Dean rubs it out and makes sure to get every last drop squeezed. He finishes the rimjob with a couple soft kisses on the hole, then slides up alongside Cas and drapes his arm around him. He goes in for a kiss, which Cas weakly returns. He likes tasting himself on Dean's lip.

"How was that?" Dean asks.

"Very good," the angel says with a smile, staring at Dean as he catches his breath. "I'll return the favor at bedtime."

"That sounds awesome," Dean grins. "Really awesome. Have you used that toy I got you?"

Cas blushes and quickly mumbles, "yes."

"You like it?"

He nods.

"We should play with that, too."

"Perhaps." Cas turns on his side and hugs Dean tight just for a moment, then he starts to get up. "Mary has begun to ask about your job."

"Yeah, and? Hasn't she always?"

Cas stands from the bed and gets his pants on. "That's true, but she's inquiring about the nature of demons and spirits more. I know that she's been reading our books and I'm fine with it, I want her to know, however I'm afraid her curiosity is expanding at an alarming rate."

"She's cooped up in here all day and wondering about the world outside these walls. Can't blame her."

Cas looks at Dean with sad, worried eyes. "What are we going to do?"

Dean sighs. "I dunno, Cas. We gotta think about it."
