Am I genuinely unhinged enough to write an A/B/O Fic? Time to find out. Buckle up, it's time for bad-wolf-science-turned-fic-trope!

"Have I told you lately how good you smell?" Kuon asked, coming up behind his mate in the kitchen and burying his face in her neck.

Kyoko bit her lip and leaned back against her alpha, her hands pressing his arms to her. "Well, my heat is coming up soon…."

"Ooh," he nipped at her neck, right above her scent glands. "Fun."

"Y'know, I have an appointment tomorrow."

"Mmm?" He hummed, too entranced by her scent to figure out where the conversation was going.

"With my OBGYN."

"Mhmm?" He nosed more insistently at her scent glands, wanting to mix their scents.

"And I was thinking…." She turned in his hold, linking her arms around his neck and stretching up to scent-mark him. "What if we started trying for a pup?"

Kuon froze, eyes blown wide. He drew back enough to look at her. "Really?"

She nodded with heavy-lidded eyes. "Really. I can talk to the doctor about going off my birth control before my heat. What do you think?"

"I think that I want to rip these leggings off of you and start practicing."

"Kuon, be serious!" she chided.

"I am." He nuzzled against her neck, craning his own at a weird angle. "I know that we've been talking about it for a while, but I think… I think we're finally ready. And I cannot wait to get you pregnant."

Kyoko blinked up at him, slowly, and then began to laugh. "Oh my god."

"What?"

"You have a breeding kink!" she giggled, leaning up against him. "That's so stereotypically alpha, Kuon."

"It's not - I do not have a breeding kink!" He pulled back, his face burning.

"It's okay," she cooed teasingly, "no kinkshaming here. I just -" she broke off, giggling. "You should have told me sooner! We could've played around more before the real thing."

"This feels like kinkshaming," he muttered, unclasping her hands from around his neck.

"I think it's cute." She slid her hands down him, pulling his attention with them. "So, what about it gets you going? Is it the thought of your seed filling me? The alpha feeling of claiming me so wholly?" Despite her boldness in speech, her bright cheek pinks revealed some remaining shyness. Kyoko, for all her comfort with sex now that they had been mated for so long, usually still faltered when it came to dirty talk. The exception was when Kuon was the flustered one.

"I'm not - maybe. And like…" He sighed and ran a hand through his hair. "It's.. hard to explain. It's all of that and just, the thought of being able to make a new life with you. Of seeing how your body changes and grows as you build a pup. Knowing that I had the smallest part in it."

She lifted herself onto her tiptoes and brushed a kiss against his jaw. "That's surprisingly sweet for a kink, Corn."

"I'm going to bed," he grumbled.

"Hey," she said gently, catching his hand as he turned to leave, "for real, though. Are we doing this?"

His gaze softened. "I want to, if you're ready."

Her answering smile was blinding.

Two weeks later, Kuon received a call from Kyoko in the middle of a workday. "Hello?"

A high-pitched whine answered him, like a dog in pain.

"Kyoko?" He walked away from the set, holding up a finger to tell a concerned Yukihito to wait. "What's wrong?"

"Kuon," she whimpered in a tone he knew very well. "Kuon, I'm sorry to interrupt you at work, but I - I need you."

He swallowed hard. "I thought your heat wasn't due until Thursday."

"Me, too."

He glanced at his watch. He'd been on set long enough; besides, it wasn't like he would be able to focus now that he knew his mate was desperate for him. "I'll be home as soon as I can."

"I don't - if you need to stay," she said, panting. "I can make do. I just…."

The thought of his mate making do made him need to get home even faster. "They can figure it out. I'll see you soon."

"Love you."

"Love you too, princess. Hang in there."

He honestly did not remember what excuse he gave Yashiro - Kyoko was always embarrassed about her heats, despite them being natural - but his manager seemed to understand that this was important, and promised to clear his schedule for the next couple of days. Thank the gods that they had already arranged to have Thursday onward off for her heat. He was not sure, either, how he got back to their apartment. A car was probably involved, but anything other than that was a blur.

The first thing that hit him when he opened the front door was her scent. It hit him like a wall of humidity when stepping outside in mid-summer. Except humidity didn't give him a throbbing hard-on. He locked the front door and then made his way to where he knew she would be, stripping as he went.

Kyoko had built her nest on their bed, surrounding herself with anything soft that smelled like him. The few brain cells that weren't telling him to rut and mate and breed realized that she had gone through the laundry hamper. The rest of his brain cells, however, were preoccupied by the sight before him:

Kyoko, fully nude, wildly fucking herself with a dildo that looked suspiciously like his own cock.

If he wasn't hard before, he certainly was now.

(For anyone with the spare brain cells to wonder, yes, Kyoko did have access to a 3D printer with body-safe materials. Kuon did not currently have a single brain cell to spare.)

Then her eyes met his, and suddenly she had no use for the dildo anymore. Eyes wild, she pulled him into the nest with her, exchanging the silicone for the real thing. She tossed the toy off into parts unknown of the nest before he even had a chance to lick it clean. He only had a second to mourn before he was utterly overwhelmed by hot, wet Kyoko. It seemed there would be no foreplay today.

She pulled him down, on top of her, surrounding herself with him. Her eyes were so dilated that he could barely see any gold; it was just a shimmer around her pupils. Then her mouth was on his, their tongues mating just as they were. He kept one arm anchored on the bed above her shoulder, stopping her from sliding, and used the other one to grope her aching breasts. All the while, he rutted into her, doing what she begged him for between kisses.

"Kuon - fuck - please - fuck me!"

All he could reply with was a low moan. Her mouth slid from his, making its way down to the place where his neck met his shoulder. Even after all this time, it was still her favorite spot to leave hickeys. It made sense; after all, it was where she'd left his mating mark. She worked on darkening it as he fucked her into the mattress.

He couldn't think; his mind was too taken over by Kyoko. The scent of her, wrapping around him the same way the feel of her did. The hand that had been playing with her breasts came down and pulled one of her legs up so he could hit her favorite angle. He was close. He could feel his knot forming, starting to push down his length. Determined to have her cum first, he let go of her leg and found her clit, rubbing the way she had taught him.

"Yes! God, yes!" Kyoko had always been a vocal lover. "Oh, just like that!"

She sang for him as she came apart around him. Her undoing triggered his own; his knot pushed deep inside of her as he let loose thick streams inside of her. And then they were stuck together, his knot keeping his cum inside of her.. He rolled over so that he wouldn't crush her, pulling her with him. She laid, panting, on his chest. He pressed a kiss into her sweaty hair.

"Doing okay?" he croaked after a few minutes.

"Mmmm." She nodded, starting to come back to herself. Sated and full of cock, Kyoko was content for the moment. Her heats always made it so difficult to do… well, anything other than fuck. "Water?"

With some maneuvering (she was kind of stuck on him), he managed to scoot over to the edge of the bed and open the mini-fridge built into the nightstand for just this purpose. Blind grabbing rewarded him with a water bottle. He pressed it to her burning skin (they were called heats for a reason) before unscrewing it for her and holding it to her lips. She drank greedily. Kuon wondered if she had anything to drink since her heat hit. Knowing how intense hers got, probably not. He would have to keep an eye on her to make sure her fever didn't spike.

"Thank you," she murmured, letting go of the bottle. He screwed the cap back on, his eyes glued to her wet, kiss-bruised lips. He leaned down and captured them with his own. Her arms slipped up around his neck as she reciprocated, leading to a lazy make-out session as his knot slowly deflated inside of her. Eventually, he pulled out, leaving an absolute mess of their mixed fluids to seep out between her thighs. He stared down at it. "Is it wrong to find that hot?"

And Kyoko was on him again, jerking his cock back to attention with one hand while the other tugged him down for a much more heated make-out session. There was definitely no need for lube this time as she impaled her dripping cunt on his cock, moaning. He let out a throaty groan. She was just so hot. Both in the sense that she was sexy as hell when she was using his cock like a dildo, and that she was physically warm. Her heats always made her like this - wild, wet, and oh-so-willing.

God she felt good. She was writhing on top of him, her strong, toned muscles letting her set a punishing rhythm. During the rest of her cycle, Kyoko would vary how she wanted to be fucked; in heat, she only wanted it fast and hard. This time was no exception. Her dirty talk, however, had changed.

"Fill me up," she panted. "Use me. Breed me, Kuon."

All he could do was growl in response and tug her down to darken the mating mark he had left on her neck all those years ago. He sank his teeth into her flesh - not enough to bleed, but enough to make Kyoko shriek from pleasure. Her fingernails scraped down his back as he sat up for better access to her neck. All the while, she continued her punishing pace.

All too soon, however, he felt his knot building again. Fortunately, Kyoko was already there, writhing and calling out his name as she tumbled over the edge. Her heats always made cumming easier for her - once, she had gotten off without even being touched. That was a hell of a week. Which this one was shaping up to be, too.

When he knotted her this time, she slumped on top of him, a hazy look in her eyes that told him she was close to sleep. It didn't surprise him - two orgasms so close together were draining for her. And that wasn't even counting however many she'd cranked out before he'd gotten home. So he stroked her hair as she laid on top of him, panting from the exertion.

Later, when Kyoko had fallen asleep and his knot had deflated, Kuon would clean up their mess and restock their bedside minifridge with protein-rich foods and water bottles. Later, he would put cold compresses on Kyoko's burning forehead and wipe away her sweat. Later, he would rebuild their nest, which had come apart somewhat from all the fucking. And a few weeks later, they would discover that Kyoko was indeed carrying his pup.

But for now, they laid together, panting. Kyoko drifted off, full of cock and love.

I hope you enjoyed!
