June – July 2027 (Castiel is 37 (almost 38), Dean is 39, Eden is 13 (almost 14), Adrian is 10, the twins are 6, Noah is 1 years old).

Eight months had passed since the incident with Crowley, and things had gone back to normal again. Isaac had fully recovered except for the scar on his tail and one on his leg. The scar on his forehead was barely visible and most people didn't notice it. The boy was now much more careful when he was near the street and cars, as was Lily. Eden and Adrian had always been easier to control and they always followed the rules more than the twins, but they too now knew even better why the street was so dangerous.

A couple of weeks after the Crowley incident they had gotten the puppy, Molly. The children had been very excited to have her, and the dog was much calmer than her mother but still playful. Dean still had to remind the twins that they couldn't play with Molly when she was in her dog basket, since it meant that the dog wanted to be alone and relax a little. Dean and Castiel were surprised at how much the children – even the twins – wanted to take part in taking care of Molly. They helped washing her (which often led to water fights outside), giving her food, and taking her for walks. The dog's basket had been placed in the entrance hall and Molly had access to whole house except for the doors that were closed. Kevin had sold the rest of the puppies to different new owners who lived further away, so Molly was the only one of them living close to Maggie. She had been vaccinated and fixed, and was a healthy dog.

In the summer the following year it was time for Castiel to finally get his intrauterine device (IUD). They had called Charlie about it and had scheduled an appointment with her so she could insert the device. Surgery or anesthesia was not required. They had decided to wait until summer before Castiel should have it inserted because it was problematic to find babysitters for an entire week for the children, and they didn't want to just drop all five of them off at Mary and John's house. The children's summer holidays were coming up – meaning that they could have Eden and Adrian be in summer camp for a week, and let Mary and John take care of the three other kids while Cas went through his heat.

Dean had taken half the day off to go with Castiel to Charlie's clinic. In the morning they were busy getting the children ready for school. Dean would drive them to school and then to work, but he would leave at 12:30pm to make their appointment with Charlie.

Castiel was preparing lunchboxes for the children, and Lily jumped up and down next to him.

"Papa, can I have a slice of cucumber on top of my bread with cheese?" she begged and stared up at him with her best puppy eyes.

Castiel chuckled. "Of course you can, cucumbers are healthy."

Lily cheered and ran over to Molly who was running around the room as everyone got ready for the day. Molly was almost a year old, and she was playful and curious all the time. The dog jumped happily when Lily came over to give her some attention.

Dean grinned when he came into the living room and saw Lily tumbling around with Molly. They had begun training the dog already, and she had gotten pretty good at obeying commands, even if her being a puppy sometimes made her ignore commands in favor of having fun.

"Remember to get ready and not waste too much time with the dog, sweetie," Dean told her.

"Yes, daddy," Lily replied, and shrieked when Molly licked her face. Isaac came over to play with Molly as well, while Adrian and Eden were busy packing their schoolbags.

Dean came over to Castiel who was still busy with the kids' lunch.

"I heard that the Jacksons are going on vacation for four weeks soon. At least they won't be renting their house out again," Dean chuckled. The Jacksons had been shocked to hear about who Crowley really was and what he had done to Castiel once. They had apologized a lot of times to them for having allowed Crowley to rent their house which was so close to Dean and Castiel's house, but they had thought he was just an ordinary business man looking for a place to stay for a few months while working temporarily in the city's department of his work.

"I'm glad to hear that. I really hope we won't have any more bad neighbors…" Castiel muttered.

"Yeah, me too."

Dean's injuries had healed well after his fight with Crowley. His right thigh had needed a few stitches, and his side had gotten a little cut as well. The doctors had given him the newest treatment which should reduce the scarring, and Dean usually healed well, so there was almost nothing to see. He did have a few tiny scars here and there but they weren't visible unless you looked very closely, and it wasn't something that bothered him or Cas in their daily life.

"Nervous about today?" Dean asked him suddenly.

"A little, but I trust Charlie," Castiel smiled. "I'm just worried it'll hurt." He finished up Eden's lunch, wrapped it in tin foil and put it in her lunchbox.

"Well, she told us on the phone that it shouldn't," Dean reminded him. "And you'll be fine, Cas. Charlie is not a pervert, and she's into women anyway," he chuckled.

Castiel rolled his eyes. "I know that, and it's not like she hasn't seen me down there before – she has delivered all five of our children."

Dean laughed and pushed his wing against the angel's teasingly. He grinned when Castiel gave him a playful glare and a smile before finishing Adrian's lunch.

"Why are you going to see Charlie again?" Eden asked and came over to them. They both looked up in surprise because they didn't know she had heard them talk.

"Your papa is getting some device inserted so he can't become pregnant while it's there, and Charlie has to do it," Dean explained, and kept his voice down so that the twins wouldn't hear. Lily and Isaac were busy tumbling around with Molly anyway.

"Oh," Eden spoke and looked between them. "But I thought his suppressants did that?"

Dean smirked. "They do, but he can't go into heat when he's on them…" Eden's eyes widened in understanding, and Castiel blushed like mad and slapped Dean's arm in annoyance over having told her that.

"I didn't need to know that," Eden spoke with a disgusted frown. "You're perverted, dad."

Dean burst out laughing.

"Yes, he is," Castiel muttered in agreement and scowled at his mate.

"Hey, it was your idea to get it," Dean pointed out with a grin. Castiel slapped his arm again.

Eden laughed softly at them. "I guess that means more holidays at grandma and grandpa's, then."

"Well, I was thinking that you and Adrian could spend a week in the summer camp so your grandparents don't get overloaded. But if you want, you can spend some days at your grandparents' too – if they agree," Dean said. He had stopped laughing by now but was still smirking at Cas every now and then because the angel was still blushing.

"I'd like to spend a few days at grandma and grandpa's, yeah. Then I can hang out with Jason as well," Eden smiled. "Can we go to movies then, me and Jason, if he agrees?"

"Sure, as long as you follow the rules we've set for you,"

"No, dad, I will walk around half-naked like most girls my age do, go into dark allies, cheat my way into the cinema, let guys grope me without punching them, and take drugs if they're offered to me," Eden spoke in a sarcastic tone while she rolled her eyes.

Dean laughed again. "Alright, good to know," he chuckled. "Now get ready, sweetie, we're driving soon."

Eden just smirked and got her lunchbox from Castiel before going into the entrance hall to get ready.

Castiel waved goodbye at them in the door when they left, and he smiled when he saw them waving back and the twins looking like they couldn't wait to go to the kindergarten and meet their friends again.

-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-

Dean picked up Castiel later and they drove to Charlie's clinic. They brought Noah with them because they had nowhere else to put him in the meanwhile, and Dean was sure that Charlie wouldn't mind.

"Hello there, my only angel/demon clients," Charlie grinned when they came into the room. She shook their hands like always and peered down at little Noah who was on Castiel's arm. "Hey there, little guy, getting bigger, huh?" she cooed and tickled his stomach gently. Noah shrieked and laughed up at her.

Castiel smiled at how positively Noah responded to her, and Dean chuckled.

"Yeah, he's getting bigger but is still pretty small," Dean spoke.

"Well, that's normal for submissives. I'm sure Castiel was just as small when he was Noah's age," Charlie smirked.

"According to my brother, yes," Castiel smiled and shifted Noah on his arm.

Charlie smiled at Noah one more time before looking up at them. "So," she clapped her hands together, "it seems you two want to spice up that sex life of yours and venture into the primitive mechanisms of heat sex – but without a baby coming out of it." She grinned at them when Castiel shifted in embarrassment and Dean shifted a bit on his feet as well.

"Wow, you have a talent with words, Charlie," Dean joked and smirked at her.

Charlie laughed. "Oh, you have no idea – my girlfriend Gilda says the same about me, actually," she chuckled. "Well, sit down and I'll explain the thing about the IUD to you, okay?" She gestured at the two seats next to her own seat by the desk.

They all sat down, and Castiel rocked Noah on his lap while Charlie explained.

"So, the intrauterine device – or the IUD – is basically just a tiny little device that's put into the uterus and kills the sperm cells before they can enter. There is the copper version and the hormonal version, but personally I recommend the hormonal version because it's more effective – and for women especially it's better because the copper one can actually make their periods stronger," Charlie explained. She held a sample of the device in her hands for them to see. "It lasts for about five years and then it has to be replaced, so if you want to keep having it you'll need to come back in five years to get a new one – otherwise you'll end up with another unplanned baby."

Castiel nodded in understanding. "Is the insertion complicated…?"

Charlie smiled. "Well, it's a lot easier to put them into women, but I've done it with submissives before. It takes about ten minutes and it should be pretty painless." Both Dean and Castiel nodded and she looked between them. "Still wanna do it?"

Dean looked down at Castiel who glanced back at him. The angel turned his gaze back to Charlie and said, "Yes, I'd like to go through with it."

"Cool, then follow me over to the bed. You best leave Noah with Dean in the meanwhile," Charlie told him with a smile.

Dean and Castiel got up, and the angel handed their youngest son over to the demon who gently took him. Noah made a few noises of discomfort over being moved but Dean gently shushed him.

Charlie told Castiel to undress from the waist down and to lie on his stomach on the bed – it worked better that way for submissives. Dean could tell that the angel was nervous and a bit shaky – probably because he was afraid there would be pain. The demon knew that his mate trusted Charlie, so it comforted him that it wasn't because of her that Cas was shaking a little. The angel had to spread out his wings so they didn't get in the way, which he did seem a little uncomfortable with. Again, Charlie's gender and him trusting her made him relaxed about it.

Castiel flinched when she touched him down there, and Charlie chuckled. "Don't worry, I've done this before, I know what I'm doing. Just relax and let Dean hold your hand."

Dean grinned and went over to take his mate's hand while holding Noah on his other arm. Castiel looked up at him in gratitude and held on tight to his hand. Noah was still too young to understand what was going on, so he just sat quietly on Dean's arm and blew a few bubbles with his mouth.

Charlie was gentle and she kept informing Castiel about what she was doing. It calmed him that he knew what she was going to do next.

Afterwards Castiel could get dressed again, and Dean watched him closely to see if he was feeling discomfort.

"Feeling alright, Castiel?" Charlie asked and looked at him as he sat on the bed.

"Yes, I feel fine. I don't feel it at all," he answered, sounding a little surprised that he didn't feel it.

"Good, but cramps may appear in the first 1-2 days," Charlie spoke. "And now you can go home and have all the heat sex you'd like. The chances of getting a baby are very low, and I've never had one of my clients becoming pregnant while using this device, so the risk is pretty small. Should it happen anyway then… well, let's take it from there. And you'll probably be fertile for another ten years, if not twenty, Castiel – many submissives first stop their heats when they're almost sixty years old, so you have lots of time for the heat sex," she grinned.

Castiel blinked. "Oh. But I don't think I will let myself go into heat every five weeks anyway."

"Why not?" Dean asked as a joke, and Charlie laughed.

Castiel scowled at him. "Because we can't have your parents take care of the children every five weeks, Dean."

Dean laughed. "I know, Cas, I was messing with you."

Charlie chuckled. "Well, at least the suppressants should keep your heat in check when you don't want it. Just remember that when you stop taking them, it takes around ten days before your body has gone back to its normal cycle again, so the heat doesn't come right away. Remember to start taking them again after your heat has ended – and don't take the wrong ones again…"

"I won't," Castiel promised, and scowled again when Dean laughed.

They said goodbye to Charlie, thanking her for her help, and left the clinic with their hands entwined.

-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-

Castiel had had a few abdominal cramps after the insertion of the IUD device, but it was nothing too painful. He stopped taking his suppressants shortly after the children's school holidays began, and it would be around ten days before his heat would appear. His heat was due to appear on Monday or Tuesday, so Dean would drive Eden and Adrian to summer camp Monday morning and have them pack clothes enough for a week. The twins and little Noah would be with their grandparents, and Jo had said she wouldn't mind having Noah at her place for a few days so Mary and John wouldn't have their hands too full. Mary and John loved having their grandkids over, but the twins were quite a handful and it had been a while since Jo had a little baby so she really didn't mind having him. Dean had told them that he and Cas were just having a week to themselves and that it was entirely innocent, but they both knew that the others probably knew the truth about why the kids needed babysitting for a week.

After Dean had dropped all the kids off – and trying to make excuses to the twins about why they had to spend a week holiday at their grandparents' – he finally came back home to the house. Dean had taken off in the early afternoon, but he had spent most of the day at Mary and John's home, chatting, so it was early evening now. Molly was at Mary and John's as well because Dean and Castiel were unlikely to have time or energy to walk her that week, and the twins wanted her to come along.

When Dean entered the house he found Castiel on the couch eating vanilla/strawberry ice cream and watching TV. The demon grinned when he saw his mate sitting with his knees up against his chest, his white wings pressed into the couch behind him, and his eyes wide as he watched some show about ghost hunters.

"Frightened of the TV, Cas?" Dean teased and came over to sit down next to him.

Castiel briefly looked at him before gazing back at the screen. He held the spoon for the ice cream in his hand and licked it absently. Dean's eyes followed the movement closely. "No, it's quite interesting actually. It's a show called 'The Ghostfacers' and they're at this haunted house in southern California… Why do they air this at this hour? It's only seven; what if children are watching this and get nightmares?"

"Don't know, maybe because it's not that frightening and not made like a horror movie?" Dean suggested. "The guys do seem rather goofy, after all." The angel only nodded slightly and kept staring at the TV. Dean smirked in amusement. When Castiel brought the cream box up to eat more of it, Dean leaned in and stole it from him.

"Dean!" Castiel scolded when the demon took the spoon full of ice cream intended for himself into his mouth. He glared at his mate when he laughed.

"What? I like ice cream too," Dean grinned and licked the rest of the ice cream off his lips.

Castiel's eyes were narrowed as he glared at him before he dug the spoon back into the ice cream. When Dean tried stealing it again, the angel shrieked and quickly ate the spoon full himself. Next time he tried to eat a spoon full, Dean grabbed his arm to lead it towards his own mouth instead, which resulted in Cas making a mess of himself when the spoon hit his chin. Dean laughed when he saw the ice cream smudge on his mate's chin, and the angel scowled at him before the demon leaned forwards and licked it off with his tongue in a seductive way. Castiel shivered, as did his wings, and Dean leaned back to grin at him while his tail twisted mischievously behind him.

The angel's eyes were lust blown as he stared back at Dean. The demon smirked and leaned forward again to press his lips gently against the angel's. Castiel moaned softly and closed his eyes as Dean kissed him. He opened up, allowing Dean to sneak his tongue inside and deepen their kiss. The ice cream box was forgotten in Castiel's other hand, but it was almost empty anyway. When the kiss got more intense, the box slipped out of his hand and ended in the space between his stomach and legs, making the angel flinch and gasp out loud when the cold ice cream hit him.

Dean pulled back and laughed out loud when he saw what had happened, and Castiel quickly removed the ice cream box from himself and put it on the table. His shirt was slightly sticky with ice cream now, and he glared at Dean when his mate laughed at him.

"Very funny, Dean, it was your fault," the angel grumbled. He grabbed the tissues he had put on the table earlier and cleaned himself up.

Dean just grinned in amusement. "Got too cold for you Cas?" he teased.

"Shut up."

Dean laughed again and leaned in towards Cas when the angel was done cleaning his shirt. The angel looked up with a frown when the demon guided him back onto the couch. Castiel lay down on his back, and his wings were spread out awkwardly over the back and the edge of the couch. Dean lay down on top of him, their clothed chests and stomachs touching, and claimed his mate's lips in another kiss. Castiel kissed him back hungrily, and Dean groaned in approval when the angel's hand buried itself in Dean's short, sandy colored hair. Dean's wings were spread above him, and his tail curled behind him as he devoured his mate's mouth and grinded their groins together. Castiel pulled away to gasp but Dean soon claimed his lips again.

Castiel mewled and bared his neck when the demon leaned away to kiss and suck on it.

Dean could smell that Cas was close to his heat now. The pheromones had been in the air since this morning – weak, but still there. And now they were becoming stronger as Dean pressed the angel down into the couch and sucked on his neck like he was marking him. Castiel loved it, and his hands grasped at Dean's shirt and wings but he was careful not to cut himself on the feathers.

"Your heat is coming, Cas, I can smell it," Dean growled against the angel's neck. His cock was hard and aching in his jeans, and he pushed his groin down into the angel's hip to let him know how hard he was.

Castiel gasped and clutched at Dean's back. "I know, I can sense it; it's getting so warm inside of me and I feel so wet."

"Yeah? Love when you get wet for me, Cas, it's so hot," Dean murmured possessively into the angel's neck. He breathed in the increasing pheromones and felt his feathers sharpen in response to the scent of his mate's fertility.

Castiel moaned and gasped softly when he felt his heat grow stronger. His heat could easily be induced faster when his mate aroused him, and that was what was happening now. He threw his head back, baring his neck more to his mate, and thrashed his tingling wings slightly. His ass was hot, and he could feel slick coming out of it and soak his clothes. Dean growled possessively when he could smell and sense Castiel's increasing heat.

"Dean, please, I need you," Castiel whined.

Dean immediately began pulling their clothes off, and Castiel rolled over on his stomach so Dean could unbutton his shirt below his wings and help him out of it. The angel rolled back around on his back when they were both naked, and he placed a firm hand on Dean's chest to hold him back when the demon was about to lay down on top of him again.

"Dean, we're on the couch—"

"Don't care, I wanna fuck you so badly, Cas," Dean growled in response. He was only thinking about sex now that he was so strongly under the influence of the angel's pheromones, and he tried pushing forward again but the angel kept holding him back with his hand.

"I don't want your semen all over the couch; it's hard to get out of the fabric. Put our clothes under us," Castiel ordered firmly. The angel was weak and trembling because of his heat, and Dean could easily slap his hand away if he wanted but he didn't.

Dean made an annoyed sound and quickly grabbed their lost clothes to place it under Castiel's back and ass. The angel lifted himself up to help Dean, and when he was satisfied with amounts of clothes beneath them he finally let his mate cover his body and take him. Dean immediately launched forward to kiss the angel and pressed his body down against the angel's smaller frame. Castiel's body arched up into the demon's and purred when their skin touched. Dean's muscled chest and stomach were resting on the angel's more soft body, the demon's wings spread out above them like an alpha who was marking his territory.

Dean wasted no time in spreading Cas' legs and pushing his fingers into his wet hole. Castiel mewled and bucked in response, opening up around Dean's large fingers. They were both hungry for each other, out of control, and filled to the brim with sex hormones.

After a few moments of stretching Castiel's waiting hole, Dean pulled his fingers out and grabbed the angel's thighs, placing the legs around his hips before pushing forward. Castiel lifted his backside up to allow Dean to slip into him easier, and moaned loudly when his mate's thick member penetrated him. They moaned together as they joined, and Dean leaned his body down over Castiel's before he began thrusting into him.

"Ahhh," Castiel moaned and clutched at Dean as the demon began pounding him into the couch. Dean's strong alpha scent only increased his heat hormones, which in turn increased Dean's scent as well. They clung to each other and grunted and moaned together as the demon kept thrusting hard into the angel. Castiel's legs were wrapped around Dean's waist, and he dug his heels into Dean's ass to force him further into him. Dean growled and bit into his mate's neck possessively, but without drawing any blood. It made Castiel howl in pleasure and come hard between their bodies. Castel mewled and gasped through his orgasm and felt his own come hit his stomach.

Dean snapped his hips forward a few more times before coming as well. "Fuuuck," he groaned as he came. His hips kept pumping slowly into the angel as he emptied himself inside of him, and Castiel moaned slightly in response. Afterwards, Dean slumped down over Castiel's body, panting.

"Dean, you're heavy," the angel grumbled under him.

Dean chuckled and leaned up a little, supporting himself with his hand beside Castiel's head. They were both trying to catch their breaths and they stared into each other's eyes. Dean smiled fondly at his mate and used his other hand to stroke his cheek.

"That IUD thing better work…" Dean smirked.

"Yes, I hope so too," Castiel said and closed his eyes for a bit. He leaned into Dean's hand which kept caressing his cheek gently. When Dean pulled out of him, Castiel cringed slightly and placed his feet on the couch while his knees were bent.

Dean sat up and looked down between Castiel's legs. Come was leaking out of the angel and onto the clothes beneath, and Dean's cock twitched at the sight.

Castiel could feel his heat flaring up again. "We better take the next round somewhere else." He sat up and ignored it when more of Dean's semen leaked out of him, before getting up and using his shirt to clean himself up with.

Dean smirked and got up as well. "I think I really like you when you're covered in my come."

Castiel blushed a bit before taking all the clothes off the couch and headed for the laundry room. His heat was flaring up strongly, making him walk somewhat funnily, and Dean followed after him – both of them still completely naked.

As soon as Cas had put the dirty clothes in laundry basket Dean was on him. The angel yelped softly as Dean kissed him fiercely and pinned him against the wall next to the window in the laundry room.

Castiel didn't make any protests, and let Dean push him back against the slightly cold wall. The angel gasped at the coldness and bucked forward by reflex, making Dean's hardened cock poke against his lower stomach. Dean smirked in amusement before guiding Cas over to the door instead, which he slammed shut so he could pin his mate against it.

Dean grabbed the angel and hoisted him up, and Castiel wrapped his arms and legs around Dean to keep himself up. They both moaned when Dean entered the angel again and pounded him into the door. They panted and grunted together, and Dean softened his wings so that Cas could bury his hands in them while hanging on to him. There was a loud banging noise on the door every time Dean fucked Cas into it, and they were both suddenly very happy that the kids weren't in the house, because there was no doubt it could be heard upstairs.

"Ah!" Castiel yelped and bucked heavily when Dean's tail suddenly poked against his already filled-up hole without warning. He squirmed against Dean as he held onto him, and shivered when the tail pressed insistently against his ass. The tail couldn't enter him at the moment because he wasn't stretched widely enough for that, and Dean was already pounding mercilessly into his hole. But the tail kept teasing him, making Castiel buck every now and then and make small needy sounds. His body was already ready to orgasm again under Dean's onslaught of pleasure.

Dean seemed to have sensed it, because he pushed Castiel further against the door and pressed his body further into his mate's, causing Castiel's neglected dick to get rubbed between their bodies and finally sending the angel over the edge. Castiel cried out as he finally climaxed again, and Dean followed closely behind him. Castiel moaned when Dean filled him with his warm seed again, before the demon finally put him back down.

"Sex in the laundry room? Really?" Castiel muttered and stared up at Dean.

The demon grinned. "Yeah, haven't tried that before, have we?"

"It's not the sexiest room in the house…"

"Hmm, that's not the point, Cas," Dean chuckled and nuzzled against the angel's cheek.

They went upstairs to continue their mating when Cas' body continued pumping out pheromones. As soon as they were in the bedroom, Dean pushed Castiel onto the bed on his stomach before settling himself between his mate's legs behind him.

Castiel frowned at Dean over his shoulder and flapped his wings impatiently on the bed.

Dean lay down behind his mate so that his face was right in front of the angel's pretty, little hole. He spread the angel's butt cheeks for a better view, and Castiel shivered in response. Dean teased his thumb over the small, pink hole which was still covered in some of Dean's come. He smeared the come into the angel's ass and buttocks, and smirked when he heard Cas made a small noise. He leaned forward licked at his mate's entrance. Castiel responded by groaning loudly and burying his face in his pillow. His white wings flapped slightly on the bed and he wriggled his ass a little.

Dean's body was demanding that he fucked Cas again, but he wanted to taste his mate for a few more minutes. He rubbed his rock hard erection into the sheets to relieve some of the need and aching in his dick, and continued licking at the angel's puckered hole which was wet and twitching. Castiel was always clean down there because submissives' bodies automatically cleaned themselves, and he knew Cas washed himself daily. The scent was amazing. It was where the heat pheromones were the strongest, and the slick had an inviting, sweet taste.

Castiel continued writhing on the bed and burying his face in the pillows. He grasped the sheets tightly while his wings gave another impatient flap. "Please, Dean, you're so cruel when you tease me like that…"

Dean chuckled. "Yeah? My dick thinks the same."

"Then listen to it like you always do," Castiel groaned in annoyance, and moved his ass back against Dean's face to state his point.

Dean wasn't able to keep himself back anymore anyway – Cas' scent and taste was too inviting and intoxicating. He moved up and settled himself on top of the angel, pinning him on the bed under his own body. He quickly grabbed his dick and guided it back into the waiting body beneath him, and let out a long moan as the angel's heat wrapped around him again. Castiel whined and pushed back against him, taking him further inside. Soon, Dean was pounding into his mate at full force, making Cas cry out every time Dean struck his prostate and cervix. Castiel's wings flapped helplessly on the bed, but Dean's stronger wings on top of them kept them down. They moaned as their wings touched, and the bed was creaking under them. Castiel's toes curled in pleasure and he felt completely at Dean's mercy as the demon pumped into him hard and fast.

"Dean – ahhh! – feels so good, I can't…" Castiel muttered, and rubbed himself against the sheets while Dean continued his brutal pace. The demon was so deep inside of him that he could only gasp at the feeling. He was stretched wide open on his cock and forced to just take it as his mate pounded him into the mattress, and the angel loved every second of it. The noises he was making were embarrassing but he couldn't care less at the moment.

Dean nuzzled the angel's neck from behind, an oddly affectionate gesture during their not so innocent act. His hands were buried in the soft wings, stroking and stimulating them, and he could feel the angel's ass clenching around him whenever he touched just the right spots on the wings.

"Come, Cas," Dean ordered. "Wanna feel you come apart under me, knowing that I did that to you," he growled with possessiveness in his voice.

Castiel mewled and buried his face in the pillow. He grasped the sheets tightly and his body tensed up as he came, spurting into the sheets under him. His ass clenched down around Dean's cock inside of him, and his hips made small, abandoned movements against the sheets while he came. Dean followed after a few seconds, filling him once more before pulling out and letting the rest of his come coat the angel's back and ass, and some of his feathers.

Castiel purred and went boneless on the bed. His wings twitched slightly, and Dean's seed was warm and wet on his skin. He didn't protest when Dean started rubbing the come further into his skin, marking him.

Dean collapsed on the bed next to Castiel, and they caught their breaths and stared lazily at each other. Their scents were mixing in their air, and the room smelled heavily of sex.

Dean smirked. "That was pretty awesome. I didn't think we'd get to do this again, ever."

Castiel smiled, still lying on his stomach with his head on the pillow. "I know, it was good. I'm glad you're enjoying it."

"I hope it's not just me who's enjoying it, though?"

Castiel chuckled softly. "No, I quite enjoy it as well. It's just unpleasant right when my heat flares up, but you're a great help."

"Glad to be of service," Dean smirked. Castiel laughed softly.

They went again a few minutes later and continued coupling whenever the angel's pheromones were strongest. They did different positions but mostly kept to the bedroom. When making dinner, they also ended up doing it in the kitchen and one more time on the couch with sheets under them.

-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-

Three days in, Castiel woke up again when his heat flared up. They had only slept for five hours, and now his body was demanding his mate's attention once more. He groaned and rolled over to face Dean who was still sleeping. They both slept naked during his heat so they were always ready for more sexual interaction, so the angel sat up and pulled the sheets away. He took Dean's soft cock in his hand and gave it a few strokes. His own cock was already hard and his hole was warm and wet and waiting to be filled. Dean slowly began to stir and wake up, and Castiel shifted so that he was straddling Dean's legs while stroking him, and he leaned down over the demon's body while supporting himself with a hand on the bed. Dean's wings were in the way, so Castiel's hand was on top of some of the feathers, preventing Dean from moving his wing. Dean blinked down at him when Castiel licked his way up Dean's lower abdomen, over his stomach and belly button, and up to his chest. The demon shivered, and Castiel could feel the muscles shift against his tongue. The cock in his hand was swelling with blood and becoming rock hard in his grip.

"Already ready to go again, Cas?" Dean spoke in amusement after he had glanced at the clock. The room was dark because it was only 4am, and Dean reached his hand over to turn on some light so he could better see Cas and what he was doing. The switch next to him turned on the small lamp on the nightstand, and the switch next to it turned on the light in the ceiling. He pressed them both because he enjoyed watching Cas touch him.

Castiel was still leaning over him and looked down at him. "It's not like I can control it, Dean. I need you again…"

Dean's pupils were dilated with lust, and a low rumble sounded in his chest. "Hands and knees then, and spread your pretty legs for me."

Castiel immediately obeyed, and Dean got up to kneel behind his mate as the angel got up on all fours and presented himself to Dean. The white wings lowered and spread out in submission, and the angel's hole was already wet and leaking slick down the back of Castiel's thighs.

Dean growled at the delicious scent and at how Cas was offering himself to him. He placed his hands on the angel's hips and thrust into him in one go. Castiel gasped loudly when he was fully penetrated without warning. He was still loose from earlier so Dean didn't need to stretch him. The angel mewled and thrust his ass back against Dean greedily, who was now balls deep in him and had begun thrusting.

"Harder," Castiel moaned.

Dean complied and rubbed his hands over the angel's sides and wings as he increased the pace and force of his thrusts. He looked down at were his cock was disappearing into the impossibly tight ass of his mate, and he almost couldn't believe that such a little hole could contain him. Castiel was making noises under him that were downright pornographic but it was sweet music to Dean's ears. He smirked smugly when he gently pinched one of the angel's oil glands without warning and caused Castiel to yelp and jolt in surprise. Dean rubbed his thumb over the leaking oil glands and watched as the oil flowed down over the angel's back. The scent of the sweet oil mixed with the heat pheromones, making the demon feel dizzy for a moment.

Castiel's noises were becoming more and more needy, and he stretched his arms out in front of him; making his upper body lower down towards the bed while his ass was up in the air and being brutally pounded into. His wings were still spread out submissively to his sides. He looked a lot like a cat stretching, and Dean's cock gave an interested twitch inside the angel. The demon bit his lip and suppressed the orgasm that was about to roll through him. He could feel that Castiel was just a few moments away from coming as well, so he quickly reached down under his mate and grabbed his dick, squeezing it.

Castiel let out a surprised yelp and growled in annoyance when Dean squeezed his dick and stopped him from coming. He turned his head to look at Dean over his shoulder and gave him an angry and confused glare.

Dean grinned and slowed down his pace. "Sorry, but you can't come yet, Cas, I have other plans."

"What would that be?" Castiel snapped lightly, sill annoyed that his orgasm was cut off. His body felt cheated and frustrated because he had been so close. And now Dean was slowing down, making his body cry out for more stimulation.

Dean just smirked and pressed his thumb against the angel's hole next to his own cock. He slowly began stretching the angel further, preparing him to take his tail as well. Castiel let out a needy moan when he realized Dean's intentions, and he pushed back against the demon's fingers.

"You know, sometimes I really don't get how your pretty, little ass can take so much of me, Cas," Dean murmured while he stretched and prepared him for more. His tail curled and twisted behind him impatiently. His tail wasn't particularly sensitive since it was so muscled, but Dean liked fucking his mate with it; Cas always felt warm and wet around his tail, and the sounds and reactions he made were gloriously hot every time. He didn't use his tail very often because it took time to prepare Cas, and he knew that the angel was always a bit sore afterwards over being stretched so wide.

"Ahh," Castiel gasped under him and mewled softly. "Well, you do feel impossibly big when you have both of your parts inside me, but you know I like it. And hurry up, I can't take it anymore," he whined, and grasped the sheets in frustration.

Dean rubbed the angel's ass with his other hand in a soothing gesture. "Shhh, just need to get you ready to take me. Believe me, I want nothing more than to fuck that sweet ass of yours for hours, so it's pretty hard for me to take my time here," he smirked. Castiel just groaned and lowered his head.

When Cas was properly stretched, Dean finally moved his tail up and began pushing it inside, slowly, next to his dick.

"Nrruuughhh," Castiel groaned and panted heavily as the tail entered him further.

"Fuck," Dean growled as the space inside the angel became cramped. The spike of his tail glided deliciously along his shaft inside the angel, and he could tell it was rubbing right over Castiel's prostrate and cervix, causing Cas to almost collapse on the bed in pleasure, but Dean's hands on his hips kept him up.

"Ahh! Dean stop, no further, I can't take it," Castiel gasped. His mouth was open in awe, and his wings flapped on the bed helplessly.

Dean's tail was already pretty far inside – just as far as his dick was – and he rubbed Castiel's sides with his hands to make him relax. He could feel Cas clenching up and his body go tense at the intrusion, and the angel was without doubt feeling a little uncomfortable at the moment. Dean experimentally thrust forward a bit before almost pulling out. When he thrust forward again, Cas began moaning and his body relaxed. Dean kept a close eye on Cas' reactions as he slowly increased the pace and began twisting his tail inside of him.

Castiel was a moaning and mewling mess now. He was practically boneless with pleasure, and his upper body was almost pressed into the bed. Dean had always liked that Cas was pretty flexible.

When Dean could feel his orgasm threatening to overwhelm him, he twisted his tail further and pressed it hard against Castiel's oversensitive cervix. The angel howled in pleasure and came hard under him, and his whole body shook through it and he clenched down around Dean. The demon thrust into him three more times before coming as well and flooding Castiel with his come. He leaned down over Cas' back as he slowly snapped his hips forwards with every stream of come that came out of him. Castiel just took it and moaned quietly.

When it was over they both collapsed on the bed next to each other with their faces buried in their pillows. Dean was lying half on top of Cas' right wing, and his own wing rested over the angel's body. He was too exhausted and lazy to move.

"Fuck that was good. Felt like three orgasms at once," Dean grinned into his pillow.

Castiel chortled against his own pillow and turned his head to look at his mate. "Mmm, yes, that was very satisfactory." Now it was Dean's turn to chortle.

"Feel sore?" Dean asked, and glanced at Cas in worry with his head on the pillow. They still hadn't moved an inch.

"Yes, a little, but I don't mind."

Dean smiled at him and finally rolled away from the angel's wing. He shifted over on his side and started pulling Cas closer. The angel reluctantly shifted as well so that he was snuggled up against Dean. They wrapped their wings around each other in a cocoon, and Castiel smiled and closed his eyes while he rested his head against Dean's chest. The demon stroked his hair and feathers lazily, and Castiel hand was wrapped around Dean and gently caressed the place where the demon's tail joined with his body. The demon hummed in approval.

"We should do this at least twice a year, Cas," Dean murmured with a smirk.

Castiel hummed in agreement and was too tired to reply with words. Dean just chuckled at him and placed a soft kiss on top of his head.

"I love you, Cas."

Castiel smiled and snuggled closer to him. "I love you too, Dean."

Author's notes: A long chapter filled with more heat sex, I hope you are satisfied ;) I don't know if there will be more heat sex in this story… maybe there will. I'm actually starting to run low on ideas for chapters, but this story is so ridiculously long already that I guess it's not really a surprise. I do have a few things in mind, though. I'll update as frequently as I can, but maybe not as frequently as I have during the summer.

And Charlie's girlfriend Gilda is the one from the "LARP and the real girl" episode in season 8 – the fairy that Charlie kissed, in case you forgot about her.

Thanks for reading my story, please review :)
