She'd spent a good long time up on that mountain; at least a month. The lonely Winterhorn which had encased her in ice had sired an entire herd of fawns, and the Keyblade Master had her hands full taking care of them. Her fawns were not belligerent, but they were energetic and inquisitive, and often scampered away through the powdery snow, cavorting and whickering so that she knew they thought it was a game.

Aqua didn't mind, of course. Her babies were, to pardon the pun, quite the little dears.

Eventually the herd grew fast enough and strong enough that Aqua knew that they didn't need her protection and guidance anymore. Indeed, before long she found herself sometimes struggling to keep up with them in the deeper snows. They were made for winter landscapes, whereas she… wasn't. Confident that her offspring were grown and ready to face the world (and, if she was being truthful, more than a little lustful to mother a few more) Aqua bade her farewells and left the mountain.

Her wandering feet took her to a familiar place; the jungle where she had met the beehive, an encounter that somehow seemed to have just happened yesterday while also simultaneously being a lifetime ago. She had been a different woman, then… different, and yet the same.

Her womb twinged at the thought of incubating some of those eggs again. Could she find the hive and spend more time as their eggbearer? Perhaps… but the Realm of Darkness was a crossroads of both time and space, and not easily navigable.

Yet there was small harm in trying.

She had been a few days in the jungle when she first realized she was being tracked. It was something small, little more than the snap of brittle branches, but her practiced ears knew unnatural sounds when they heard them. Aqua spun, summoning her Keyblade in an instant, a lattice of ice crystallizing at the tip and coating her blade with rime. Behind her, the jungle was quiet. There were vines swaying as if from a light breeze, and a few disturbed fronds, but otherwise… nothing.

Aqua had come this way before and already shown off her strength to the resident Heartless. Any creature that tried itself against her would therefore be inordinately brave… or very, very stupid.

Still, caution was never detrimental. Aqua stalked back, retracing her steps, ice spell still at the ready. Her eyes scanned the jungle. Though she'd spent a very significant amount of time in the Realm now (and had personally helped populate it) she hadn't forgotten just how vicious the Heartless could be. A single misstep could cost Aqua both her heart and her chance to breed some sense into the creatures.

There was nothing behind her that she could see, but there were still signs of pursuit. Branches snapped clean that were too healthy to have broken naturally. Torn ferns that had been whole when she'd passed. And most damning: noticeably impressed earth. What made her stop was the size of the thing. The footprint was vaguely reptilian, with four digits: three in front and one in back. It was also enormous; a single one of the digits looked to be nearly as big as her arms. How had she missed a creature of such a large size?

A chittering sound hit her ears, and Aqua spun, her Keyblade still carrying magic on its tip. Her eyes narrowed. There was nothing to be seen there in the jungle—nothing except a wavy, almost watery sensation, like air warped by heat. The watery sensation moved and she cursed, launching her spell. It burst against a tree, instantly cocooning the growth in frost.

She'd missed, but there was little doubt: a Heartless was on her trail.

Keeping her Keyblade level, Aqua turned, readying herself. Most Heartless were either blindly aggressive or meek and cowardly. This calculated pursuit was something new, something she hadn't dealt with. Was the creature just curiously investigating her? Or did it have darker intentions?

Minutes passed with no sign of her chaser, so Aqua was forced to slowly resume her trek through the jungle, keeping a wary eye out. Yet signs of the illusory Heartless still showed themselves—distant noises, flashes of waving light behind vines or trees, and occasional fresh footprints, each as massive as the last.

Aqua didn't know whether to be intimidated or impressed that such a titanic specimen could be so adept at keeping hidden.

As she continued journeying, the strange creature seemed to slowly be drawing closer and closer. Her tension spiking, Aqua decided to let it. If it was that big, then disguised or not, it would be easier to fight in close quarters.

Seemingly letting her guard down, the Keyblade Master dismissed her weapon with a yawn and settled against a giant moss-grown root as if to sleep. Keeping her eyes cracked open and her ears sharp, she readied herself. Unless it could phase through solid wood (unlikely) then the creature would have two approaches. The forward one, across the ground, or…

A sound touched her ears, the delicate brushing of a claw against wood, coming from right above her. Yes, the other approach was from above.

Summoning her Keyblade, Aqua unleashed a Thundaga spell with a cry, the lightning pealing across the jungle. She cartwheeled out from her position just in time; sparking and spasming, the invisible Heartless crashed down to the base of the tree in paralysis, careening its voice in shock. Illusions melting away like snow in spring.

Aqua's breath caught. She had seen massive Heartless before, but this one took the cake. It most vividly resembled a bipedal chameleon, its scales a brilliant green overlaid with sweeping, sharp black patterns, almost like tattoos. Its eye was a vivid orange, and the by-now-familiar crossed heart sigil was present on its front. It was truly massive, by far eclipsing even the Dark Hide in size; a human such as herself was perhaps as tall as its knee. Even as it righted itself, holding itself hunched over to the ground, it was still easily at least triple her height. Later, for its behavior, she would dub it the “Stealth Sneak." For now, all she knew was that it was a potential threat.

Aqua kept her Keyblade trained on the creature, the tip glowing with power. This would be a formidable adversary if it came to blows, though she had no doubt she could handle it. Still, she was yet again intrigued by its behavior. Upon attacking it, she had expected it to lash out, or scurry and flee once it was devoid of the element of surprise. Instead, the creature turned its head this way and that, casting an inquisitive gaze her way, clicking slightly. Its foreclaws clacked a few times—not an aggressive gesture, she realized, but something almost akin to a nervous tic. It didn't seem to have been greatly damaged by her Thundaga spell.

Making a decision, Aqua took a step back, and then another, keeping her blade trained all the while. The Stealth Sneak didn't move, still surveying her with that inscrutable gaze. Slowly, Aqua lowered her Keyblade, though she didn't dismiss it. “What are you after?" she said warily. “Prey?"

The creature clicked and took a step forward but froze as Aqua immediately leveled her Keyblade with it again. It looked perturbed. Aqua frowned. The Stealth Sneak wasn't the usual sort of creature she bred with. Large, powerful, and forward, it lacked the timidity or friendliness of her usual monstrous paramours. Yet, nor was it aggressive. And looking at its size and the fact that it could cloak, if it had wanted to bumrush her at the very start, it easily could have.

“No," she murmured, “if you wanted my heart, you had multiple opportunities to act. So what are you after?"

After a minute, the lizard took a tentative step forward, and when Aqua didn't react, another—and before long it was on her. Peering and chittering at her, the Stealth Sneak lowered one of its claws and with a level of gentleness that was, for its size, quite impressive, stroked her bare shoulder.

The Keyblade Master gasped. The touch was electric, sending her body racing with a wild thrill. Immediately she felt a flush of want down in her loins. This creature… did it have intentions? A powerful Heartless that didn't hunt her as prey… it would make for an ideal mate.

Another sensation brushed against her legs; glancing down, Aqua saw the tip of the Stealth Sneak's sinuous tail wending its way up one of her legs, stopping to delicately brush the pocket of bare skin on her thighs where her stockings fell shy of her shorts.

Feeling her cheeks burn, her heart palpitating, Aqua surrendered and dismissed her Keyblade. She'd gone looking for the bees, but this creature was more than good enough.

With a delighted croon, the giant reptile snaked its tail up even more, the tip squeezing underneath her shorts and panties to kiss against her moist outer lips.

Aqua's breath slid out of her in a hiss. This wasn't even the creature's cock and yet already the smooth, cool scales felt so good as they sawed back and forth against her, the pace slow and luxurious as a direct rebuttal to the thundering skip of her heart. One lengthy push from the Stealth Sneak's tail ended up inadvertently stroking her clit with its caressing scales and she sagged against the larger creature, breath ragged and heaving out of her. “F-fuck," she moaned. “Oh… oh fuck…"

The Stealth Sneak crooned more and then suddenly, Aqua was aware that the creature's anatomy was changing. She allowed the creature to step away from her, its lengthy tail more than long enough to continue stumming her full of pleasure, and watched awed as a barely-visible slit between the monster's legs began to spread. Unfurling from the slit was quite the impressive package indeed_._

The Dark Hide might have finally met its match, Aqua thought with delight as she watched the Stealth Sneak's member manifest. It was a long, uniform, slightly curved thing that was colored a purplish pink. For most of its length, it was roughly as big around as her wrist—relatively modest, considering the thing's overall size, but still titanic to a normal human like her. It was almost as long as one of Aqua's legs from hip to foot, and the tip abruptly tapered to near pinpoint size. From what little she knew of reptilian anatomy, Aqua had vaguely expected a pair of penises; still, this massive member was more than impressive enough, and she found herself looking at it with eagerness.

The creature chittered and, as if spurred on by seeing her delight, plunged its tail into her.

Aqua's cheeks alit with pleasure and she crooned and keened. The reptilian tail was deceptively smooth, gliding easily through her, and she quickly helped it along with her slick juices. The small ribbed scales on it tickled and caressed her inner walls, and Aqua surrendered to its ministrations as it plundered her depths.

The Stealth Sneak, intrigued by its choice of paramour, reached down and, with deceptive dexterity, actually used its great claws to peel off Aqua's outfit. The Keyblade Master watched it unfold with undisguised interest. Normally she was the one who had to take care of this part, but the reptilian Heartless was crafty enough to deduce how her clothing worked and to disrobe her without damaging any of her wear. One by one, her clothes were cast aside: her loose sleeves, the wrap around her hips, her skin-tight top and shorts, even her bra and panties. As Aqua stepped out of her metal boots, the Stealth Sneak's tail popped out of her, making her gasp, and the sinuous tip caressed her thighs before hooking into her stockings and slowly peeling them down. When the process was repeated for the other stocking, she was left bare, naked, and wanting.

The absence of the Heartless's tail in her had left Aqua feeling empty, but she was a patient woman. She knew that something even better was coming her way. Bending over, the Stealth Sneak picked her up with the same ease a human might employ picking up a doll. Before long, Aqua found herself in the creature's grip, the jungle floor below her, the thick rod quivering and aligned with her pussy. She almost felt giddy. While she still thought she could take the Stealth Sneak if push came to shove, for the moment she was very much in the thing's mercy—and she found that she quite liked it!

With a high keening cry, the Stealth Sneak's grip on her tightened, and then it both pulled her down and bucked its hips up in one smooth motion, penetrating her. Immediately, Aqua was rendered near insensate with bliss.

The tapered, tiny tip of the thing kissed its way into her, making her squeal with delight, but soon enough it was followed by even more. The Stealth Sneak was broad and wide and very quickly spread her far apart, and Aqua danced delightedly on it, wriggling her hips in an attempt to take in as much as she could. There was no way to fit the whole thing in, of course; that was impossible. But she was enough of a size queen to want as much as was manageable.

She wriggled further, swinging her hips and clenching tight and exulting in the feeling of the monster in her. It had been far, far too long! The lizard, pleased, crooned again and swung its hips up even more, thrusting deep inside of Aqua and leaving her wide-eyed and rolling with bliss.

“Fuck," Aqua said, her voice a throaty gasp. She bounced up and down, working it in even farther in time with the Stealth Sneak's thrusts. “F-Fuck… you're so big, and so perfect, and_—mmphgl?!"_

Her vocalizings were cut off by a sudden presence in her mouth. The Stealth Sneak had thrust its long, dexterous tongue into her, and Aqua's eyes widened as the lizard's tongue pressed deep inside. She felt her throat bulge as she was made to deep-throat the creature's tongue, and with a placid moan she leaned her head back, giving it easier access to plump her throat. The tongue was thick, bigger than most human cocks, and warm and wet and pulsing, and Aqua shuddered as it thrust into her face in time with the Stealth Sneak gleefully ravaging her pussy. She reached one tremulous hand to her throat and felt it bulging out obscenely; the tongue pulsated and squelched even deeper into her, and Aqua tensed as she felt the bulge dance under her touch. The sensation made her clench even tighter around the presence in her pussy, and she exulted that monsters truly did make for the most wonderful lovers.

But the best was yet to come. The Stealth Sneak had almost fit as much of itself into Aqua as it could; already the Keyblade Master could feel the thing's tapered tip squatting next to her cervix. Holding tight to her arms, the Stealth Sneak yanked down, and Aqua nearly fainted from the cascade of bliss as the slight tip strolled right into her innermost sanctum.

This is it, she thought giddily. It's going to cum right into my womb. I can't wait…

But there was more to it than that. The creature tensed and heaved and its rod pulsated, but in a way that Aqua didn't usually associated with monster cock. Swallowing around the tongue in her mouth that was still stroking her throat, she wondered what was happening.

Above her, the Stealth Sneak closed its eyes, focusing again, and then visibly strained—and then a bulge showed up in the creature's rod.

Aqua was floored. She'd thought this was a male monster with a cock, but her suppositions had been entirely incorrect. This was… it was…

A female looking for an incubator! She wasn't riding a cock, but another ovipositor!

Aqua moaned around the Stealth Sneak's squelching tongue, her voice vague and distorted. At this point she had no choice but to accept the eggs—not that she would have said no. As with the Queen Bee and the Wicked Spider, the fact that these offspring weren't biologically hers didn't mean a thing. She would happily nurture this creature's young.

The mother reptile strained again, its hands tightening their grip on Aqua's arms, and the bulge traveled lower. Aqua followed it with interest. The egg was making the already-huge ovipositor strain around it; how would she take having it put inside of her?

As it turned out: well. She would take it quite well.

The bulge met her lower lips and immediately a sense of strain hit Aqua as the egg—easily half again as large as a human fist—was pressed into her. She heaved breath through her nose, throat swallowing vainly around the Stealth Sneak's tongue, and focused everything she had on her cunt, trying to spread herself as wide as possible. Finally, inch by inch, the egg muscled its way in, the force and the pressure completely dominant, an all-encompassing feeling that stopped Aqua from focusing or thinking on anything else. As the egg moved in, her own body began to morph around it, and when it plopped into her womb, the act both sharp and blissful and wracking her body with orgasm, she already had a visible bump.

But more were coming.

The Stealth Sneak's voice was a counterpoint to Aqua's, low and ragged with lust. Still, the creature found time to reward its new incubator by pressing its tongue even deeper, and Aqua gulped and swallowed as she felt it slide lower and lower, down nearly to her stomach. The presence of the thing inside of her, right below her sternum, was impossible, and feeling it slide up and down left her aroused in ways she never thought possible.

Around the time the Stealth Sneak rewarded her with a particularly deep thrust of its tongue, the second egg squeezed into her, and Aqua lost all coherent thought. She was vaguely aware of still being gripped by the Heartless; of the tongue that was throat-fucking her as deep and as intimate as possible; of egg after egg filing inside of her, making her moan and keen; of her belly swelling out, rounding in its familiar way, as she was stuffed full of monster babies. The whole time she was washed over with bliss, cumming again and again, and what little notions floated into her head was that it had been far too long since she'd let herself get fucked.

But that was a thought for later. For now, the Keyblade Master was more than content to buoy along on waves of bliss as the Stealth Sneak filled her with children.

It was good to be back.
