[Size Difference, Unbirth, Breeding]

"Ehehehehe. You really are cute when we're the same size, Jin."

"And you're enjoying your time being that small way too much. We look like a couple of kids, you know."

"Is that a bad thing? You don't want to fuck a lil' girl who can keep your cock as warm as it needs to be?"

"I prefer it when I can stuff my face in between your tits and just rut you until I'm dry, Asphodel. But... I guess having you about the same size as my cock isn't a bad thing either."

"You're such a terrible liar. But that's part of why I love you, my sweet little breeder."

Two young kids, or at least what looked like kids, were currently strolling down the street with their hands woven together and both smiling more than one might expect. Then again, the sun was shining down, the birds were singing, and everything was just right for a date between those two youngsters.

Of course they weren't actually young. Far from it. While the boy, Jin, was just unnaturally short for his age, the girl was far beyond the point where you could call her a mere girl. She was a demon, and a very matronly one at that. Asphodel was her name, and despite the very cute way she carried herself while she was like this, she was still as dominant as she'd be if she were to tower over her dear partner.

"Speaking of breeding..." Jin muttered as he felt his crotch twitching and trembling. "I've been waiting to let it all out. You mind turning back ye-" He paused, right as his eyes managed to glaze towards a rather fertile looking woman, which almost caused his pants to tear up from the way they became awfully tented.

Asphodel giggled as she watched the process, before planting a kiss on his cheek. "Don't worry. I'll handle that." She said, while also planting a kiss on his tip to make it calm down ever slightly. Just so she could skip over towards the blonde bombshell that was currently pouring over a trashy magazine, seemingly not interested with the world.

"God, isn't there anything to do today..?" The blonde muttered as she put down the magazine, before laying her eyes on the young white-haired girl and that elegant red dress. "Hm? What's the matter, kid? Never seen a girl like me before? You'd better just get going, you're... not going to..."

As she stared into the red-hatted girl's eyes for a little too long, it was like her mind slowly turned to mush. Like... Like there was something she should be remembering, but all she could think about was how cute she was. Not only that, but how much she... Mommy...

"Oops. Maybe I went a bit too far." Asphodel giggled. As a demon, she had several powers available to her. One of them being the regressive aura that kept her in control whenever she was with somebody else. Well, whenever she was with somebody not named Jin. He was able to endure it for the most part, and give her a fuck like no other. But humans like this blonde were so pitifully weak to it that it almost seemed a little mean to unleash it like that...

The short lil' gal climbed onto the bench and carefully caressed the very curvy lady's head as she watched her rock back and forth. "There there. There there. It's okay. Mommy is here. Mommy loves you, okay?" She said, giggling as she made sure that the girl wasn't falling as far down as she possibly could.

"Mommy... Ehehehehe..." The blonde chimed, slowly slipping off the front of the bench as Mommy reoriented herself and let her head rest up against her thighs. All while she felt those nice hands press against her head. It felt nice...

Jin watched it unfold, and he had to admit that it made him feel a bit more aroused than he thought. Mostly because Asphodel was going through the trouble of preparing a bitch for him to fuck. While he'd prefer her, he definitely found this new gal really appetizing. "Get her ready, Asphodel. I..."

"Of course. Just hold still for a little longer." Asphodel chimed, all while her eyes glowed a little and she focused her efforts on the lady that had fallen under her spell. "Okay, dear? Spread your legs a little. There's a cute boy that wants to play a game with you. And you gotta let him stick his nice big stick into you. You can do that, right?"

"Yes, Mommy..." The blonde giggled as she spread her legs, just as Mommy told her to. Revealing her absolutely adorable pair of striped panties, and how absolutely soaked she was. Part of being regressed and put under Asphodel's spell like this made you utterly aroused. It was part of why she was able to tame and include so many in her massive family. All because of her sweet words and a little nudge here and there...

Not that she was the one in control. No, Jin grabbed those reins as soon as the blonde spread her legs and jammed his cock straight into her hole. That absolutely massive cock that was absurd for any human, much less a Demon like Asphodel...

The blonde woman let out a powerful moan as she was forced to take it all inside. Her eyes immediately rolled into the back of her head as the regressive effects were almost nullified, though Asphodel's sweet hands made sure that her mind remained in such an easily manipulated state. All while the young lady moaned and screamed. "M-MommY! MOMMY!" She couldn't handle it. This much pleasure was far too much for her...

"There there. There there. You're doing great. Just clench down and let him cum inside you. Then you'll feel so good. Mommy promises it'll feel like nothing you've ever felt before." Asphodel giggled. Ah, seeing Jin fuck like this... It was more than enough to turn her on. She almost wanted to swap out right then and there. Actually, come to think of it...

Ah, no, that was why she felt so wonderful helping him like this. It was less like they were just sex friends that hooked up to satisfy each others' urges. It was like... Yeah, it was like he was actually part of the family. Perhaps she should take the next step, after she had satisfied her own needs...

Her train of thought was forced off its rails as she heard the sound of her dear Jin crying out intensely, and the sound of so much cum pouring out that it was almost impossible to think. And for the woman that had been manipulated by her, it was definitely impossible.

Having that much cum swim around inside of her belly, to the point where she already looked like she had been pregnant for months with a baker's dozen... It was too much for her to handle. Her brain was completely and utterly broken after that rush, as she just giggled and drooled like the broken toy that she was. Even pulling out revealed that she wasn't going to recover from that ramming either, as a ton of that cum came rushing out of her incredibly gaping pussy...

"Can't say that I like how quickly girls break after I've been with you, Asphodel." Jin muttered. Even though he had managed to cum, it wasn't nearly as satisfying as filling the pale-skinned Demon. Which was why he was already so terribly hard. He really just wanted to cum again. Again, and again, and again. Specifically inside her. So he could knock her up or at the very least leave her so bloated she couldn't stand. Both results would satisfy him.

Asphodel nodded. "Well, it's what happens when you lay with a Demon." She chimed, all while carefully caressing the girl that had been fucked silly. "There there. There there." She whispered gently, all while she slowly lifted up the hem of her dress. Letting that head slip a little inside. All while smiling as serenely and as softly as she possibly could.

Only for a sharp gulping sound to echo out. As the woman slowly and surely started to disappear up that terribly tiny skirt. Jin could watch her slide in between those thighs. All while Asphodel's belly grew bigger and bigger. She was... She was pulling her into her pussy. An act that he had seen her do a few times, especially as they were out together.

It... Well, okay, he had nothing he could say about it besides that it made him horribly aroused. Even though he was watching somebody get practically eaten by somebody's lower lips, it was stimulating. Because he knew that he could handle that pussy. He could tame it. And right after she had pulled somebody into her womb was the moment where she was the most aroused. Which meant that he was going to get one of the best fucks of his life when they were done...

As for the woman that had been fucked silly, there was very little that she could feel other than pleasure. So she went straight into Mommy's womb as easily as she possibly could. Sliding inside with absolutely no resistance, all so she could be reborn as one of Asphodel's young in the near future...

And as a result, Asphodel was as red in the face as she possibly could be. She was burning down below, panting and gasping as she struggled to close her legs after all that. Well, it was all thanks to still being in her terribly young state. A little aging up, and she would be perfect. All she had to do was take a little breath, and then...

Jin watched as his beloved sex friend grew and grew. From a girl around his own size, to a woman that was so unfathomably bigger that it was almost a little unbelievable. Then again, Asphodel did tell him that she was always going to be bigger than whoever she was with. As long as she was in her fully maternal state, nobody would be able to be bigger than her. She was always there to tower over them...

And even after all that growth, even after she had filled out her dress to the point where it almost seemed like it would snap in several places, especially with how big her belly still was, she still looked like she was ready to fuck. Rather excessively so, as a pool of sticky juices had formed on the ground in front of her. And she had a look of utter need on her face, that would probably help too.

Jin approached, though he didn't get far. As soon as he put one foot on that sticky juice, he felt a shock rush through him. And if he were to look down at his balls, those massive things that were always packed so tightly inside of his pants, he could see that there was a kiss marked onto them. "What..? What did you do, Asphodel..?"

"Just a little something to spice this up... You really think I'm going to have you cum and be done with it on a date like this, Jin?" Asphodel giggled, all while spreading her legs and resting her arms on top of her own gravidity. "You need to cum as hard as you can. Every time you climax. Otherwise this wouldn't be a real date. You can do that, can't you?" She chimed, as she dangled a dangerous challenge in front of him...

Jin listened. And Jin did what made most sense. He climbed onto the bench and immediately slammed his cock as deep into Asphodel as it could possibly go. Because of course something like that wouldn't deter him. It would never deter somebody like him, especially when this massive woman that he had pumped so much cum into over the last few months was in front of him...

Asphodel chuckled. She anticipated this. And she let it happen. She let him slam and ram into him as hard as he possibly could, all while she bit into her lower lip and hugged her belly for a bit of support. Because while she was used to a lot, having him fuck her like this was never something that she could get used to.

It was one of the reasons why their relationship had gotten this far. And why she wanted to have him as one of her dear sons. Because if he was there to give her a fuck like this every time, then she could always rely on him making sure that she was satisfied. Then she could keep him close and make sure that he was satisfied too. Because she didn't want him to go around and wait for somebody to fill, especially when they couldn't get him to cum the same way that she did.

Jin was one of the ones that laid so close to her heart that she didn't want him to be disappointed. And she made sure that he knew that, through the way that she tightened down on him. She wanted to make sure that he had the best possible fuck that he could ever experience. And that meant having her lower lips wring around him even though she hadn't climaxed yet.

Of course he wouldn't stop fucking her just because she was tight. He was used to tight holes. And even though she was one of the tightest holes that he had ever fucked, that wouldn't stop him. He just amped up his thrusts to make sure that he broke through her proverbial defenses, and made sure to slam as hard as he possibly could. Harder and harder and harder, until he could feel his hips giving way... And then even harder, to make sure that she didn't think he was going easy on her!

Their moans poured out through the park around them. And nobody batted an eye, because of the powers that Asphodel radiated. Even though she was fucked to the point where most would be knocked senseless, she could keep them from being disturbed. Even as she felt him reaching deep into her womb to the point where he was close to smashing straight into her ovaries, straight past the woman that would become one of her dear daughters...

It felt so good. Asphodel loved the way that she felt whenever he did this. She wanted him to keep going. But she also needed to make sure that he was tuckered out to the point where he would be broken. Then, and only then, would she feel like she could comfortably pull him inside. So she needed to tighten down just a little more, especially around the base of his cock. And then he would do the rest all on his own.

Jin's eyes widened as he felt the pressure intensify near the base of his cock. It was like he was stuck in place. It was like she had trapped him inside of her. And... And that meant that she was practically begging for him to slam her harder than he ever had before, to break past her defenses and lay claim to her womb!

As soon as he slammed straight in to try and break through, he managed to overwhelm himself. The sheer pleasure of having his cock be released from her tight grip was enough to make him cum. And thanks to the mark on his balls, he just kept on cumming. The sheer flow of it all was far beyond was he was used to. Sure, he was used to cumming far beyond what anybody would consider normal, but this was far beyond that.

Asphodel very quickly started to bloat outward. If not for the specific properties of her womb, her newest daughter might've just gotten drowned due to the excess of it all. But instead, the cum that was pouring into her and making her look like she was full of several dozen kids would serve as nourishment. Especially with how much she was being filled with.

She was used to this much cum. Not just because of how often she fucked Jin to satisfy an itch, but the kind of breeding and child rearing that she partook in meant that she would naturally be this excessively filled. And it meant that her body had naturally adapted to handle that much cum. It meant that even though her belly was now trying to push the boy outward and try to force him out of her, she didn't feel any discomfort. If anything, getting this huge only made sense to her...

And soon enough, the flow started to taper off. As she looked like she had an entire village's worth of cum stuffed into her womb, as she looked like she could be birthing for a whole week, Jin finally started to slow down and stop cumming. He was filled with so much cum that she ended up this big... It was actually kind of astonishing that he held back this much to try and drag out their sessions, but at the same time... If she got filled that much this often, she would probably end up getting a smidge loose...

"There there... That's an excellent-"

Just as she thought that he was done, she felt a thrust. And then another. And then her eyes started to widen as she realized that he hadn't stopped. Oh, he was done cumming, but that didn't mean that he was done fucking her. Which... Which should be impossible, and yet...

It would hardly be the first time that Jin had surprised her. Especially when she was most vulnerable. The way that he rammed into her, the way that her entire body trembled as he fucked her while all of that cum sloshed around inside of her... Oh, good god... She was getting weak. Not literally, but... What else could she describe herself as, when her eyes kept flashing with hearts replacing her irises?

"You... You really don't know when to quit trying to milk me too early, Asphodel..." Jin panted as he was almost being crushed by that enormous belly. Cumming his entire supply of seed out in one big burst had taken a lot out of him. But it wouldn't put him down for the count. He still had a lot of stamina to go. And it also didn't help that her pussy was practically sucking him in every time he thrust.

But she really was one of the lays that he had ever been with. Only somebody like her would force him to go this far. Only somebody like her would make him feel like he wasn't even close to done even though he had emptied what felt like a river's worth of cum into her. And only she would inspire him to keep fucking like his life depended on it.

So he put as much of his power into her as he possibly could. He thrust and thrust like he really, desperately needed to. The sheer intensity of how he was thrusting meant that if he ever slowed down, the adrenaline would catch up with him and cause him to realize just how much he was hurting his body. But that didn't matter. He needed to satisfy himself. He needed to reach that personal climax, one that Asphodel hadn't forced him to experience.

All backed to the tempo of Asphodel's loving moans. She was being overwhelmed by the way that he was fucking her. She was being overwhelmed in general. And as soon as he would cum for real, she'd be the one to pass out for once. That would be a good way to cap off their date. Having him proverbially win, and...

Why did that suction down below grow stron-

For a split second, Jin lost his concentration. And just like that, the pussy that had been accepting his cock and allowing him to thrust in with such wild abandon that it seemed like he would break it... It slurped him up like he was nothing more than a snack. He couldn't process what happened, nor could he process anything else than pleasure.

Asphodel was in much the same boat. Because she was left in such a weak state thanks to how he had been fucking her, she couldn't stop her body from doing what came naturally. Somebody that was able to breed her to this extent would be perfect for her family. She herself had acknowledged it. So of course her body would stop him from getting away by slurping him up. It only made sense. Even as it put an end to the way that she was being fucked, her body didn't stop slurping him up until he was stuck inside the sea of cum that he had let loose inside her. She didn't even really feel the way that he had been pulled inside, as the pleasure just mixed together...

And yet it didn't stop. Even though Jin had been slurped into her, the pleasure didn't come to a decisive end. Because he still needed to cum. And now that he was cumming inside of her, she just kept growing and growing and... And...

To say that Asphodel was overwhelmed would be an understatement. To say that she couldn't handle this any longer would also be an understatement. The oversized Matron admitted defeat and passed out on the bench, trembling and panting as her stomach continued to bloat outward and upward.

She didn't know what would happen when she woke up. All that she knew was that she was utterly addicted to this feeling. And she never wanted it to stop...

---

"Mommy..."

Asphodel's eyes slowly but surely started to flutter open as she heard a sweet voice. A sweet, comforting and boyish voice. Ah, it was one of her sons, wasn't it? He had come to see her..? How adorable. Then again, she had been out for most of the day. It only made sense that he would come by to make sure that she was okay. Especially since she had left her entire family alone while she was out having fun with Jin.

The oversized Matron yawned as her eyes slowly focused on the boy sitting at her side. And she blinked a few times. Hold on, he was... Distinctly familiar. Like she had... just been fucking him... a few hours prior... And the kiss mark that was pressed against his cheek only served to solidify that.

"J-Jin..."

"Mmhm." Jin giggled as he pressed his lips up against Asphodel's. All while he looked just like another one of her dear sons. Same pale skin, same white hair, same crimson eyes. The main difference was his characteristic cock and balls, which seemed to be even larger than when he was human. "Didn't think you'd end up stuffing me into your womb, Mommy. But I can't say I don't like it." He said with a grin, putting extra teasing emphasis on the affectionate title that Asphodel now deserved.

She sighed. And she felt her pussy trembling. Yeah, she needed him. And he needed her, judging by the way that he was throbbing just as much as she was trembling. So naturally she started to spread her legs, revealing just how soaked the bed underneath them were. She didn't even register that they had returned home, just that she now had a loving and extremely hung son.

"Satisfy Mommy, will you, Jin?" Asphodel chimed, as her eyes started to flash. She didn't need to use her powers or anything. But she wanted to make sure that he did everything that he possibly could. Not just because he was one of the few that could fuck her hard enough to make her cum over and over, but because... Well, after knocking her up that badly, she was in the mood for another intense round...

Jin smiled as his own crimson eyes glowed, and his cock started to leak a little. He moved over between her thighs, put his hands on the gravidity that he had bestowed upon her with his rivers of cum...

And then he picked up where he had left off, their moans serving to emphasize the new chapter in their relationship...
