As part of her campaign to subjugate Remnant, Salem has convinced her female subordinates to give their bodies to the cause and breed as many Grimm as they can. First, it was Cinder Fall. Now, it's Neo's turn... for some Grimm Breeding!

Part 2 of a commission series for anonymous. Other chapters can be read in the "Grimm Breeding" folder. The thumbnail is art of a king taijitu from the mobile game RWBY: Amity Arena.


Salem's silent assassin still couldn't believe what was happening. Her? A breeder of Grimm? Could it be real?

She, Cinder, and Emerald had offered themselves to Salem's plan—Cinder first of all, then Emerald following the Autumn Maiden's lead, then Neo coming behind. That decision had been made yesterday, but it almost seemed like it took place a lifetime ago. Had she really agreed to surrender her body to such a plan?

Within Salem's palace—a sinister construct of red stone at the edge of the world through which the Grimm prowled—distant echoes sounded down the halls. They were faint, but Neo's ears picked up on them expertly. They were two women she knew well: Cinder and Emerald, each moaning in orgastic bliss. Both women sounded like they were being roughly, firmly, desperately pleasured as they offered their bodies to bestial babymaking. Against her better judgment, Neo felt her hands getting clammy. She rubbed her fingers against her palms, licking her lips. Her whole body suddenly tightened with a whipcord-like tension; she felt arousal thrum down to her womanhood, her labia starting to spread as her pussy moistened with arousal.

Closing her eyes, the assassin heard Cinder's voice rise in a high, desperate note. Whatever was happening, it sounded like Cinder was enjoying it. Neo pictured herself in the maiden's place, keening out as she was bent over and rutted again and again, her body parting around monster cock…

She didn't hear the chamber door open or the sound of someone new entering. It wasn't until she felt the hand on her cheek that she started, her body tightening at the unanticipated touch. Snapping her eyes open, Neo gazed up at Salem, who was smiling maternally down at her.

The scourge of Remnant was everything Neo was not: her skin chalky and white, almost corpse-like, while Neo's was pink and flush with health. Her simple, umbral gown was in stark defiance to Neo's quirky, lacy ensemble; her regal bearing contrasted with Neo's impish playfulness. To say nothing of their heights: Salem was tall and commanding, while Neo was short even for a woman. Her head barely leveled with Salem's breasts.

“Enjoying the sound of your cohorts attending to their new duties, are we?" Salem said. Her voice was somehow both sultry and motherly; comforting and commanding, yet providing an inescapable hint of the lewd indulgence that was to come. “They've fully committed to a future of birthing monster babies. And oh, what a future it will be." Her hand, smooth and confident, moved from cupping Neo's chin to glide down her neck and settle on the dip between it and her shoulder. She squeezed and Neo gasped despite herself. “Are you ready?" Salem asked. Neo could only swallow.

With Salem's hand on her shoulder, Neo was guided out of the waiting room and down the halls of the palace. The echoes of Cinder and Emerald's bliss rang out louder and louder; the pink-haired woman wondered if she would be joining them in a communal room…

But it was not to be. Salem steered her down a side path and into an absolutely massive chamber, one spacious enough to house a small cottage inside it while still boasting considerable wiggle room. The chamber was lushly furnished, with fresh velvet cushions, pots of incense filling it with a spicy scent, and an absolutely massive divan. Neo couldn't help but marvel. How had Salem managed to furnish such a place?

They stepped into the chamber and the door shut behind them, the sound thudding with a muted echo. Neo took a few tentative steps, eyes wide with wonder and heart a-flutter.

Salem's grip on her shoulder tightened, stopping her from going any farther, and Neo halted and looked up at her expectantly. Salem just smirked down at her and reached to play with a strand of Neo's hair; not the strawberry-colored right half, but the cocoa left. “You really are a treat," she said to herself. “Oh, the beasts are going to love you."

Neo swallowed, feeling anticipatory fire snap through her like a freshly broken twig. Salem just chuckled and traced one ashen hand south; Neo's breath tightened as the woman's touch settled down on her breasts, toying with the single large button that did her jacket up. “Let's get rid of this, shall we?" Salem said. “After all, you won't be needing clothes any more." And before waiting for Neo's input, she swiftly undid the button and began undressing her subordinate.

Neo tightened as Salem's touch ghosted over her. The towering woman quickly peeled back her cream-colored jacket, revealing tight breasts under a charcoal-colored corset; humming to herself, Salem plucked the jacket off of her, caressing it once before idly tossing it aside. Despite the fact that her top was still mostly covered, Neo felt strangely naked with her arms exposed to the air; her hands were still gloved, however.

Stepping back to survey her work, Salem glanced down at Neo's knee-high, heeled leather boots and raised one eyebrow. The message was clear. Part of Neo didn't want to take them off—she really liked those boots, like how elegant they made her feel and enjoyed the inches they added to her already-scant height—but she had to admit, they would do nothing but get in the way during a mating session. With trembling hands, the silent assassin reached down and brushed her fingers against the lacework, undoing them with a practiced hand. One boot was loosened and then the other, and she set them carefully aside, cogent that she was now even more diminutive than before. What remained was her black corset, her form-fitting pants, her belt, her gloves, and the necklaces looped around her neck.

Salem's eyes were fixated on the belt next, and Neo very deliberately began undoing it, slipping the clasp out of its notch and unfurling the brown leather from about her waist. She was so small that the belt had enough space to coil around her body twice.

With the belt gone, her pants threatened to sag down on their own and Neo, feeling a blush coloring her cheeks, helped them. Her lower body was suddenly all but bare, only a pair of frilly, pale pink panties—colored even lighter than her hair—shielding her womanhood. Neo's blush deepened as she realized that her panties were sopping wet, stained with girljuice from how worked up she was. Without her pants to mask it, the scent of heady arousal filled the chamber.

Salem smirked at that. “Oh, so you are ready," she murred. “Good, good… I was worried that you might want to back out, but it seems that listening to your sisters-in-arms helped you realize just what a delight you're in for, hmmm?"

As if to punctuate her point, a high, desperate squeal—Emerald's voice, it had to be—sounded from outside the chamber, rolling into a long, ragged moan that sounded like nothing less than sexual bliss incarnate. Neo tried swallowing again, but her mouth was completely dry.

A lean smile etched into her face, Salem reached out to loosen Neo's corset, but the smaller woman shied away, suddenly bashful.

Salem's smile faltered for the briefest of moments, though when she spoke, it was with disappointment, not anger. “Oh? Suddenly shy, are we?" she inquired.

Neo blushed more. Some had seen her body, like her roguish, handsome, charming Roman… but although she had readied herself to mate with Grimm, somehow letting Salem see her nudeness was a bridge too far.

The Grimm's mistress folded her arms into her sleeves. “Oh, believe me, your form has no enticement for me other than how it serves to bring more beasts into the world," she said. Her voice was smooth, and the disappointment was giving way to a quiet amusement. “And I've already seen the bodies of your companions, after all. You agreed to become my broodmother, did you not? So why the hesitation? Surely I can't be worse than a beast…?"

She had a point. Whatever Neo's hesitations were, they didn't make sense now that she had committed to this path—and she would not be surrendering anything more than Cinder and Emerald had done already.

With trembling fingers, Neo reached up and unlaced her corset. The black, clinging garment relaxed, letting her breathe just a touch easier, and as she pulled it off of her, her breasts settled free. Neo wasn't exactly flat-chested, but she didn't have the full figure of someone like Yang Xiao Long, either. Still, given that her breasts were usually constrained by her corset and hidden by the layers she wore atop them, she knew that her real size could be surprising to some. Salem's eyebrows lifted in appreciation and she glided over.

Neo hissed as Salem's touch brushed against her chest, taking in her lip as her superior gave one of her boobs a firm squeeze. “Bigger than I expected," Salem said appreciatively. “Not quite maternal, but once you lie with the Grimm, that will change." She threaded her fingers up Neo's now-bare torso, gliding along her collarbone, before stopping to play with her necklaces. “I think we can allow you to keep these for old time's sake," Salem said after a moment's consideration. Her finger toyed with one piece of jewelry; it made a slight tinkling sound. “The gloves too. But of course, if you really are to breed, then one more thing has to go…"

Neo followed her gaze south. Her pink panties were sopping wet and the only thing shielding her most delicate area from the outside world. Reaching down with trembling hands, Neo hitched her fingers around her underwear's frilled hem and, after a moment's hesitation, she tugged them down, revealing her flushed womanhood, crowned by a neatly-trimmed tuft; like her hair up top, the tuft blended pink and brown.

Casting her panties aside, Neo breathed in once and met Salem's eyes. The taller woman seemed pleased.

“Very well done," she said. “Your service for my cause has shown you to be competent, ruthless, and driven. Now, it's time for you to embrace your true destiny and spend the rest of your days transferring those qualities to your spawn, empowering and emboldening them…" She clapped her hands, the sound sharp and ringing, and the far end of the chamber roared with false thunder as the stone wall rose like a portcullis. Movement and chittering noises sounded from the shadows pooling on the other side.

“But first," Salem continued resting her hand on Neo's shoulder, “a gift from me to you, to… ease you along your journey." Neo gasped—she felt shadow spooling out of Salem's touch and into her body. She shuddered as it seeped invisibly into her, settling in her veins, her breasts… she all but moaned as the foreign sensation nestled down inside her womb.

She staggered but was held up by Salem's touch, and as the sensation whispered away—a flash of cold, fluid like trickling snowmelt—she cast a wide-eyed gaze up at the other woman. Though she couldn't speak, her query was clear as day: What did you do to me?!

Salem's smile never faltered. “I decided your mistress Cinder was best put to use breeding the more normal-sized Grimm," she said, “and Emerald has her own destiny in store… but not all Grimm can match sizes with humans. Goliaths, manticores, feilongs… these titans are deserving of having their numbers swelled, but even the human body, flexible as Aura makes it, can only stretch so far. At least… not without a little outside help." Salem's grip tightened on Neo's shoulder and the smaller woman's heart hammered away as the wall continued to raise. Did Salem really expect her to breed with the giant species? She thought she'd be mating with the likes of beowolves! How was she supposed to squeeze them out?

The wall finished rising and the occupant of the pen behind it slithered out. Neo nearly fainted. A massive beast, two-headed and dual colored, with a trunklike body dozens of feet long and a circumference the size of a car… a king taijitu, the great serpent Grimm.

“I thought about starting you off with a goliath," Salem said conversationally, “but decided to take things small at first." Neo's head spun. This was small? The taijitu coiled at the edge of the chamber, forked tongue flickering, and she saw that at the place its two bodies met was a pair of hemipenes, ripe and pink, purple-tinged cum already beading at the tip. “You'll bear this creature's offspring and we'll move you to larger fry, hmm?"

Neo stared at her assigned paramour. Its massive body undulated and knocked over the divan. How was she supposed to make love to, and bear the children of, such a gargantuan thing?

She tensed as if to bolt, but Salem's grip remained tight and icy. Neo half-expected the witch to erupt in fury. But instead, Salem's voice was calm and level.

“I can understand your hesitation," she said. “But I have no intention of breaking my toys. Rest assured, my gift to you will ensure you can accommodate this being and its progeny without issue. And besides… think of what you stand to gain." She paused for a moment and the next word dripped from her mouth like honey:

“Vengeance."

Neo's fear and doubts were suddenly assailed by memories of Roman, dear Roman… He hadn't deserved his end!

“Cinder told me of your paramour's fate," Salem said, entwining her arms about Neo's body in a twisted embrace. “Such a tragedy. Do you know what really killed him? Huntsmen and Huntresses themselves—not just an individual, but the whole system." She bent; her lips brushed Neo's ear and her next words were a whisper. “Maybe a woman of your talents could kill the Huntress responsible, but would that really sate your vengeance? One woman can't make war on a system… but an army of offspring, inheriting their mother's drive and talent, just might." She stayed silent for a moment, letting the implication of it hang in the air. On the other end of the chamber, the taijitu was still undulating, cocks on display.

“Make the right choice," Salem hissed, withdrawing her hands from Neo's shoulders. And Neo—Neo—

She took a step forward. Because Salem was right—she couldn't upend Remnant like her beloved Roman would have wanted. But a horde of powerful Grimm could see it through.

The creature dipped one massive head low at her, serpentine head sniffing. Its onyx scales glinted in the orange light; the other, pearly-scaled one hung back. A forked tongue slithered out of the black head to rub a stripe along her body, tasting and testing her. She felt its warmth against her like the sun. She didn't flinch or doubt; she was entirely committed to her new role. In fact, she found herself even excited; the touch of the tongue on her body filled her with a bountiful need.

Seemingly liking what it found, the taijitu coiled about her, encircling her in a lock of black and white scales. Its muscles were strong and powerful and easily maneuvered her towards its quivering, waiting cocks. Neo's breath picked up; she took one of her hands and, heedless of the designer's glove still covering it, rubbed along her outer lips, teasing her entrance before dipping in to swirl against her clit. The touch sent a typhoon of want and need through her, and she crooned out a wordless plea.

One of the serpent's two cocks teased against her and she found herself very, very thankful that its members were unlike those of a mammal. The tip was extremely slender, so fine that it almost seemed to narrow to a pinpoint; it tapered out in a long, smooth shape, curving like an exotic toy. The taijitu's cocks were comparatively small for a being its size; at their widest girth, the hemipenes were slightly larger around than Neo's own arm. Far bigger than anything she'd ever had in her, but probably manageable… she hoped.

The tip of the snake's dick was dribbling pre; the fluid was translucent, tinged purple, and aromatic, like spiced punch. As it dragged its member down between her legs, simply the touch of the fluid set Neo's whole body suddenly aflame with desire. She whimpered and panted, trying as best she could to spread her legs despite her coiled state. It was the closest to an invitation she could manage.

“The thing about Grimm," Salem said, watching from the edge of the chamber with a pleased look, “is that they are animals of raw instinct. To most people, that means that they are things to be feared, simply hunting and killing without abandon. But to be one's mate, why… it is to surrender yourself to the passions of a beast that is nothing less than a primal force of nature."

The great serpent angled itself and the outermost tip of its slender cock managed to pierce into Neo; she whimpered, clenching and rolling her hips, trying to milk this thing for as much as it was worth.

“Oh yes," Salem continued, “You'll know quite intimately what it is like to be well and truly bred. I hear nothing in the whole world can compare."

With a sibilant hiss, the Grimm twisted its body and a full third of its member surged into Neo. The assassin's vision filled with sunbursts as she was abruptly stuffed full of serpent cock; she opened her mouth but only a quiet moan trickled out. She hung limp in the taijitu's coils before rolling her eyes down. There, impossibly, her tight, trim tummy was bulging out around the taijitu's hugeness, its shape clearly visible. She heaved a ragged breath and the serpent slid out of her only to press in again. She could feel her body stretching to accommodate it, her stomach bulging out to an unreal size. And what was more, she felt absolutely delightful; her womanhood was sending rushes of pleasure through her, making her quake and tremble with every push. At one point, Neo tried clenching tight around the serpent's cock and nearly passed out for the sensation. It was beyond unreal.

Humming to herself, Salem sauntered over. The taijitu gave her no heed; in fact, as one of the heads kept its attention on Neo, the other dipped low, letting her stroke it like a pet.

“To taste such bliss as you are made love to by the Grimm," she said, “and to know that this pleasure will lead to your just revenge… why, you must be the luckiest girl in the world. What do you think, Neo?"

The mute woman couldn't answer, of course, but her agreement was writ large on her face. The way her unfocused eyes stared up at nothing, the way her tongue lolled out of an open mouth… with every rutting push the taijitu slammed into her body making her distend about it, she just surrendered more and more to its ministrations. Yes… this was wonderful. Marvelous, even!

Smirking, Salem reached out one slender finger to toy with Neo's hair once more; she curled a strawberry-colored lock around her knuckle. “You know, I think I chose wisely when it came to your first paramour," she said. “The taijitu is a being of opposites, black and white scales both…"

As if to punctuate her point, the Grimm shifted, popping one of its two cocks out of Neo only to thrust the other in. Her eyes rolled into the back of her head and the snake's other head looked pleased. A small bit of fluid leaking out of her showed it had already seeded her once.

“And you're also a creature of duality, aren't you?" Salem smiled, letting her hand trail down to the assassin's modest breasts—she gave them a squeeze. She wouldn't be petite for long; soon enough her chest would plumpen out as her body worked overdrive to nourish her young. “Your hair and even your eyes, they are twinned just like this creature is."

Neo gave no indication she even heard her; she continued moaning and rocking in the taijitu's coils. Salem just folded her arms into her sleeves and left the chamber, looking pleased.

“Worry not, quiet one. I'm sure you'll enjoy your new life."


The remainder of Neo's time in the clutches of the taijitu passed like a blur; she could only vaguely recollect getting seeded by both cocks, then the taijitu taking turns with her again; had it pressed its massive forked tongue into her mouth as a parody of lovemaking, the gift making her cheeks and throat bulge, or was that just a dream? After what seemed like hours it had finally had its fill; the Grimm had left her, slithering back into its warren behind the wall, and she, quivering and soaked in cum, had crawled over to the divan to curl up for a night's rest.

When she woke the following morning, she found it difficult to rise. Not just because of how thoroughly fucked she'd been, though indeed she was left tender and wincing. No, there was something else.

Impossibly, despite the fact it had been hours at most, her body was changing. She'd put on maternal weight around her hips, which had plumped out to leave her quite stacked; her breasts had to have increased at least two cups in size and felt tender. To say nothing of her belly—she looked nine months along at least, and could feel creatures squirming within.

Neo was able to take a few staggered steps before she collapsed under her own weight, panting and groaning.

The door to the far end of the chamber opened soon after. Salem strolled in. “Well!" she said, sounding pleased. “I was expecting you to be sizable by the end, but this is a surprise. You're coming along quite nicely!"

Neo panted and shot her boss a glance. How was she supposed to deal with a pregnancy like this…?

As if answering her pleas, Salem continued. “Yes," she said, “this won't exactly be a usual pregnancy. Grimm breed fast… You'll have your young in about three weeks or so."

Neo swallowed. That fast? She hadn't expected that.

“I wonder how big you'll grow in the meantime," Salem said. “Now, I expect that nourishing young that big and heavy will be quite taxing. You must be starving."

The word triggered something in her, and Neo was instantly aware of how true it was. She… was starving. Beyond measure. Smirking, Salem stepped aside, and a tall, jellyfish-like Grimm pushed in a cart laden with—

Ice cream. Neapolitan. Well, never let it be said that Salem didn't have a sense of humor.

Neo tried to rise and was too laden to do so, so the Grimm pushed the cart over to her and she started digging in.


Her day was spent lounging, lazing, and resting. Throughout it all, her stomach grew and grew—bigger, ever bigger. Her breasts, too. Before long they were even bigger than they had been before, milk beading out of them. Neo surveyed them with awe and wonder. This was only a single day into it…

By the time night fell, she was officially too pregnant to move. She was left resting on her massive stomach like it was a pillow or a beanbag, her body supported and suspended by the weight beneath. Her newly thick ass cushioned the air and her breasts rested on her roundness. Neo tried to rest, but she was woken by the sensation of the infant Grimm inside of her. There had to have been at least half a dozen baby taijitu nurtured in her womb; not even birthed yet and each was nearly as long as a person was tall. She could feel them coiling, writhing, undulating about each other, occasionally nipping one another and fighting. Her massive, strained tummy danced with bumps at their activity.

At first Neo had wondered why she wasn't developing eggs, but then she remembered that many snakes, like sharks, gave live birth. What was more was that the stretch and strain of being this large wasn't uncomfortable; it strained her, but the sensation was pleasant, almost like popping a knuckle after a long time spending stiff. She had to assume that Salem's 'gift' was responsible for that. As she blinked blearily, desiring sleep yet unable to claim it for the wakefulness of her young, she wondered about Cinder and Emerald. How big had they gotten? Were they, too, immobile?

Hours passed and the young finally quieted enough to let her doze off; when she woke, it was to the pressure of coils and the familiar taste of cock.

The king taijitu had returned, both heads eying her. One nudged her belly, seeming pleased when the offspring within nudged back, and the other let its tongue dance against her nipple, teasing out milk. Neo groaned; she had grown even more in the night. Now her stomach was larger than her height and with an even wider circumference, her breasts complementarily huge. She let her arms and legs hang limply down. Only her third day out of what—twenty? And she was already completely immobile…

One of the snakes dipped its head down between her cushioned, pillowy ass, and fire filled her at the touch of its hot tongue to her womanhood. Electric need danced through her, making her horny unlike anything she'd ever felt before. Perhaps being a Grimm's mate had changed her…

The taijitu ate her out for a few long, luscious moments before angling itself. She was larger than before and it didn't even try to lift her, instead wreathing her body with its own like a bow. Its cock found her outer lips and she sang as it pleasured her. With every thrust, the baby snakes packed within her womb wriggled with activity, burying her under an avalanche of sensation. It didn't take her long to cum, but the taijitu kept right on fucking her through it, and she sobbed when it eventually filled her with bliss. Who knew vengeance could taste so sweet?

And so it went. Day after day, she spent dozing in the times her young allowed; when she was awake, she let herself wash over in thoughts or simply luxuriate in the feeling of monstrous motherhood. The taijitu often came to fuck her, which she appreciated, and Salem ensured she was well fed.

And she grew. Oh, oh how she grew. By the end of the first week she was as big as a car. Then a room. Then even larger…

She quickly realized just exactly why Salem had arranged a chamber as large as it was. None of the baby Grimm were as large as their sire, but they were close, and she was carrying six or more of them. By the end, she was nearly big enough to fill the space.

Her due date fell on the nineteenth day after her insemination, and Salem made sure to attend. Neo's face was flushed and she sobbed her way through it, feeling her tunnel part around the first of her children. It stretched and strained her even more than the taijitu's cock had. Her house-sized bulk shrank ever-so-much as the first of her young slipped out…

The infant grim plopped down onto a cushion and Salem stroked it, crooning. Neo panted. She felt so weary, and it was only one down…!

“My my," came Salem's voice. “Look at this." Neo was immobile, of course, so she had to wait for Salem to show her. What she saw shocked her even through the throes of birth-weariness: the infant taijitu was dual-colored, like all of its kind, but its colors were pink and brown, like hers!

The dual-headed snake snuffled. Salem smiled and helped it slither its way up its mother's tummy until each of its two mouths found her teats. Neo sighed as the milk began to flow.

“Such promise already," Salem said in praise. “Your young are hale and you bear them well. I think we shan't wait too long before breeding you again, what do you think?" Neo nodded, and then winced as she felt another of the baby Grimm settle into place in her birthing canal. As she squeezed out her secondborn, her mind reeled—what did Salem have in mind for her in the future? Nevermores? Goliaths? Something even larger? How big would she grow in turn?

Well, whatever lay in store for her, that was for later. For now, she had to focus on birthing these great serpents.

Her body rocked and her breasts surrendered their bounty to her twin-headed offspring. No rest for the wicked…
