Author's response

To Kaisha00: Je suis bien en avance sur vous.

To everyone else: The one upside to waiting a long time for the money to come in is that you get restless and decide to write the next chapter anyway. Had some leftover ideas that the commissioner pitched but couldn't be fit into their request, along with one that was suggested by fellow writer Natsu is Awesome.

Wild Tigress

In Crocus, one month after Fairy Tail's disbandment…

"Wow, Lucy, when did you hit your second puberty?"

Lucy blushed and went back to packing her things. In this tiny apartment in Crocus, provided to her thanks to her job at Sorcerer Weekly, she had planned to pack up her belongings and move into the Cube full time to be with Natsu. No more polished wood floors, no more drab wooden furniture, no more featureless white walls, instead she'd be staying in… a fixer-upper, admittedly, but at least she'd be free to decorate.

What she'd forgotten was that she'd agreed to have Lisanna come for a visit today.

"It was… surprising, to say the least," Lucy admitted.

"Surprising? Here, let me help." Lisanna knelt down and began folding Lucy's tops to place in her magical suitcase. "You make it sound like it snuck up on you. It's only been two weeks since I last saw you, Lucy!"

Lucy chuckled nervously. "Well, it sort of did. One day I'm my normal, perky self, and then suddenly the next day I've got…"

She prodded her massive, braless bust. "I didn't even think to shop for new lingerie since it finished."

"Ooo-oo, now I get it." Lisanna gave a sly smile from the corner of her mouth. "Anyone I know?"

"For what?"

"Don't deny it, Lucy," Lisanna said. "The sudden growth, the sudden move, a new interest in sexy underwear-"

Lucy just about ripped the shirt she was holding. "I didn't say it had to be sexy!"

Lisanna chuckled and leaned close. "You're in love, aren't you?"

"I-! That's-!" Lucy deflated in defeat. "Yes…"

"I knew it! Who is it?! Tell me, tell me!"

Lucy reached over next to herself and began folding her socks. "I mean- Hey! Lisanna!"

The white-haired girl had a hand on Lucy's right boob, bouncing it in her palm through the overstretched fabric of her shirt. "I've never seen a girl as big as you, nevermind talked to one. Wow, these things are a lot softer than I thought."

"Quit it!" Lucy said, pushing Lisanna's hands away. "You've been spending too much time with Mirajane, you know that?"

"But I spend time with her-!" Lisanna thought for a moment. "Maybe you're right. Maybe spending most of my time with Mira and Elfman, or maybe not spending time with other people since the guild disbanded… Well, what can I say? Spend a full month with anyone and they'll probably rub off on you. Speaking of which…"

Though she hadn't cast her Animal Soul spell, Lucy could still see the cat ears popping up from Lisanna's white hair. "I already have a pretty good feeling as to who the lucky guy is… Or, is it a lucky girl? I saw Cana recently; she told me some pretty interesting stories about how she got to partner with you for the S-Class trials. Come on, Lucy, do I have to use Cat Form to smell who it is?"

Dirty thoughts started to trickle into Lucy's mind. They were thoughts of Lisanna sticking her nose in Lucy's hair, the way Natsu had. They became thoughts of herself, Natsu, Lisanna, and even Cana, but also the she-demon who'd awakened this indecent side of Lucy, a she-demon named…

"Minerva!" Natsu stomped into the remains of Hell's Core and walked up to the glowing molding tube. "Are you done yet?"

The olive-skinned tigress was busy fondling herself through her now-trademark blue bikini, while Kyoka and Ravenlord monitored the controls.

"Almost, Natsu," Minerva cooed. "Just a little more. Then I'll be back to my original size."

Ravenlord scoffed. "Dozens of ethically dubious experiments, the power to create sentience itself, and now here I am, a glorified plastic surgeon…"

"A 'plastic' surgeon?" Kyoka inquired, standing next to him and keeping her eyes on Minerva. "I didn't think human medicine could do what we do."

"It can't," Ravenlord grumbled as he put his hand on the glass. "Not without magic. Still, with a scalpel and the right knowledge, I'm certain some lunatic could rearrange a body to make it more trim or voluptuous."

Minerva hummed and licked her lips. "I love that word, 'voluptuous'. It's so… me." She squeezed her bikini-clad breasts tighter. Her fingers no longer had claws, her nails having receded to normal human ones. However, per her request, Kyoka had worked out the means to give her Etherious clothing, gloves and leggings that could shift and disappear per the wearer's demonic power, be it their size or their color. Her leggings currently came up to mid-thigh, squeezing them into a nice bulge, and her arm-length gloves were practically the same as her old ones, with one key exception. Now she, like Natsu, could sprout and dismiss claws at will, perfect for when she wanted to ravage a body softer than her man's.

Natsu folded his arms and tapped his foot. "Hurry it up, you two. We got us a job now."

Ravenlord looked over his shoulder. "And what manner of task might this involve?"

"I'll tell ya once you're done," Natsu replied.

Ravenlord placed his fingers on a glowing slider, one that Natsu didn't recognize, and said, "I believe we're ready. Now, Minerva, conjure the most vivid memory of yourself, what you used to look like. Imagine every detail you can remember: weight, sway, feeling, all of it."

"Gladly," Minerva smirked, then moaned as Ravenlord dialed the slider down to halfway. Immediately, she seemed to fill out, her boobs bulging more between her fingertips, her muscles becoming firmer, her ass and thighs getting a little curvier. It was only a second, but… Well, actually, Natsu didn't need a spank bank. He had three of the most gorgeous women in Fiore ready to ride his dick at a moment's notice. Besides, Minerva would cut off his hands if she caught him masturbating instead of fucking her.

"Aaah, that felt nice," Minerva sighed, before teleporting herself out of the tube and onto Natsu's body. "So, Natsu, how do I feel?"

"Like the top of my 'to do' list, once we get this done. Come on."

He took her by the ass and shoved her towards the exit, leaving her to drip molding fluid from herself as she walked. Thanks to her power to conjure holes to her personal dressing room, Minerva had already gotten herself a towel, her cloak, and a pair of knee-high boots by the time she left the chamber.

Ravenlord wrinkled his lip, just about the only part of his face he kept visible. "So much for informing me." He turned to Kyoka. "Am I untrustworthy? Or, is something else the source of this aversion I sense?"

"The only aversion is what you imagine," Kyoka replied, powering down the molding tube and moving to gather the half-living flesh of the squid-demon. "I think it's more the fact that you're the only other male in the guild."

"Ah, so Natsu doesn't like what he can't breed," Ravenlord sneered sarcastically. "Is that all?"

"Only the start." Kyoka smirked. "I could go down the list, if you'd like."

Meanwhile…

"Who else is coming with us?" Minerva asked. "Anyone you've fucked?"

"I was gonna try to catch Lucy on the way," Natsu said as they began their ascent up the long stone staircase. It occurred to Natsu that the inside of the Cube never quite looked the same, as if it was subtly altering its interior for some reason. Then again, this thing was a massive demon, just not one that was "awake", ever since it got skewered by the Celestial Spirit King.

"Finally," said a third voice, waiting for them atop the stairs.

Minerva licked her lips when she saw who it was. Ultear had gained the body of an amazon, with bulging muscles that made her feminine curves look even bigger. Minerva wanted to be crushed in those arms, to feel her curves bulge around those muscles like they did with Natsu's. She wanted to slide her hands along those washboard abs while those plump, sky-blue lips ate her out, watching Natsu ram his cock between those smooth, toned legs and wide hips, outlined perfectly by the indigo tights Ultear wore. She didn't even have shoes; her cute little feet were sturdier than oak when she wanted them to be.

Not to mention, Ultear had a rack that was nearly as big as Minerva's but just as perky, even after she'd returned her body to its top-tier sexiness, and an ass that looked like it could crack a walnut between its toned cheeks. Add that housewife bun that still tied her black hair behind her head, those two ivory horns that curled around her bangs like a crown, the purple granny sweater that she still wore, straining as it was to contain the pectorals hiding behind her tits, with an ever-deepening neckline as a sudden move could see it rip in half and set Ultear's pale, porcelain curves free…

"Are ya done admiring her, Minerva?" Natsu asked.

Minerva blinked and smirked. "I could never finish eye-fucking you, Natsu. Why would Ultear be any different?"

The rejuvenated mage blushed at that. "I'm… not sure what to say."

"Say something now," Natsu said, grabbing her arm and gently turning her to join their ascent. "Otherwise, she'll never stop. Minerva loves looking at sexy people."

The offhand compliment made Ultear blush harder.

"You're not wrong, Natsu," Minerva said, running a hand down the back of his arm, hungrily going between Natsu and Ultear's muscular bodies, each one enticing in its own right. "But why look when I can touch?"

"Because you get off on it?"

"Like it's your servile cock."

"His what?!"

They'd reached the top, or rather the castle-shaped foundation that would eventually become the new Tartaros guild hall, once they got the money to hire a construction crew.

Lucy was there waiting for them, suitcase towing behind her, with a skin tight t-shirt that struggled to hold in the massive amount of underboob she'd gained, along with a skirt that was basically a pair of loose shorts from how much curvy width had been added to her hip region. Between her body and Ultear's hairstyle, two polar opposite flavors of MILF would be traveling on this job, much to the harem co-owners' delight.

"His virile rocks," Minerva smirked. "Don't pretend you're not constantly thinking about them, Lucy. It's only natural, when you've been away for two weeks without Natsu inside of you."

"I'm… Not…" she said hesitantly. "Anyway, where are you all going?"

"We got us a job," Natsu said, holding up the flier. "Seems someone finally decided to try us out, see if we're legit. All we gotta do is frame some minister guy for dark magic and knock down a bridge."

"In that case, I'm coming with you!" Lucy declared.

"Oh?" Minerva raised an eyebrow at that. "Why the sudden enthusiasm?"

"Because you're horny-"

She pointed at Natsu. "-you're still a reckless hothead-"

Then at Ultear. "-and I don't know you, but you cast a spell that both rewound time and made you age rapidly. No way would I get any sleep at night, knowing you three were out and alone together."

"That spell saved your life," Ultear said sternly. "If I hadn't cast it, the dragons from the Eclipse Gate would've wiped out the continent."

"Yeah, and now you know there's a way to cheat the cost if you need to cast it again," Lucy replied.

Minerva and Natsu both frowned, then looked at Ultear with sudden realization. The power to reverse time… at the cost of rapid aging… on a woman who likely wouldn't age anymore.

"That's… actually a good point," Natsu admitted.

"I knew there was a reason to keep you around," Minerva said, before eying Lucy's gigantic bosom. "Another one, anyway."

"I wouldn't cast it on a whim," Ultear said. "Time reversal carries other hazards. There would be no telling what even a single minute of precognition could do in the wrong hands. I promise, I have no intention of ever using Last Ages again, not unless the situation is just as dire as it was then."

"Even so, I'm still coming with you," Lucy said, spinning on her heel and pointing towards the horizon. "Just because we're in a Dark Guild now doesn't mean we can't be good people! So let's go!"

Minerva smiled at Lucy's back. She was going to like the blonde, she could tell. Her energy alone was quite attractive. Lucy glanced over her shoulder and caught Minerva staring. When Minerva did naught but smile, Lucy inched closer to Natsu and took his hand in her own. It seemed Minerva hadn't fully mended their relationship yet.

Thanks to Minerva's Territory Magic, the trip was short and sweet. They could essentially jump from mountain peak to mountain peak, so long as the snowfall wasn't too hard. In Natsu's opinion, it beat vehicles any day. In Lucy's opinion, she missed the leisure of a train ride. Ultear was indifferent, though she strangely murmured something about a lack of exercise.

Soon, they'd reached the destination nation: a relatively young kingdom named Stella. Founded only about one hundred years ago, the kingdom was overseen by an oligarchical legislature headed by a mysterious king named-

"If it ain't relevant to the mission, Lucy, you don't have to explain it," Natsu said, perched atop a rock overlooking a large village, seated at the base of the mountains in a clearing and surrounded by a wooden palisade.

"Tell me more," Ultear said, taking Lucy by the arm and leading her aside. "Not all of us are country bumpkins by nurture."

While Lucy gave more about the history of Stella, Natsu sniffed the air. "I think the client's here. I got something on the wind that smells like the job post: blood, cigars, and some kind of powder, I think."

Minerva stood on her tiptoes and sniffed Natsu's hair. "So, what now, 'Master'?" Her newly enlarged bust pressed through the fabric of her cloak and against Natsu's back. "You made it sound like we'd need to be in two places at once for this."

"Might be. Hey, Lucy! Ultear! On deck!"

His call brought the two women back, Lucy still towing her suitcase over the hardened earth of the forested mountain terrain.

"So, here's the plan," Natsu said. "First, Minerva's gonna go down to meet the client. Lucy, you'll be her lookout in case someone tries something funny. Me and Ultear will stay up here in case we need to bail you out of a jam."

"Wait, wouldn't you make a better lookout, Natsu?" Lucy asked, hefting her huge bosom. "You have a better nose than me, and I'm probably going to attract attention with these things."

"Yeah, but you're a journalist for Sorcerer Weekly, right?" Natsu said.

"Not anymore," said Lucy, leaning her suitcase against a moss-covered rock. "I put in my last stories a week ago."

"That may be true," Ultear said, "but no one will know that in a place like this. You won't have to worry."

Lucy sighed. "Yeah… You're right. Just lemme get my parka. I'm freezing!"

A few minutes later, Minerva and Lucy proceeded down into the village, leaving Natsu and Ultear alone among the rocks.

"I'm curious," Ultear said, turning to her companion, "why exactly did you want me to come along?"

"Insurance," Natsu answered. "Remember how you fixed Grimoire Heart's airship after it got blown up?"

Ultear thought for a moment. "I'm surprised you remember that. That was over seven years ago."

"Not for me," Natsu said. "I skipped those seven years, remember? Anyway, I figure if the client tries to double-cross us after we blow up the bridge, you can do your rewind thing and put it all back together."

Ultear was shocked. "That's actually brilliant," she breathed, looking over the pink-haired hothead. "Were you always this smart? I don't recall you thinking this far ahead when we fought on Tenrou Island. In fact, you seemed completely driven by impulse."

"Yeah, well…" The scale-like coating of Natsu's arms slid up his skin and covered his face, this time giving him a pair of bone-like nubs on his forehead. He tapped his temple with his now-human hand, and grinned. "I've had to use this a lot more lately. Now I see why Gramps was so smart: being in charge means you gotta look at the big picture more."

Ultear pursed her cyan lips and smiled. They seemed to shine in the afternoon light reflected off the mountaintops. "Does that include who you sleep with, as well?"

"Of course it does," Natsu said. "Why? You want in?"

Ultear's brown eyes blinked, then slowly drifted downward. "So forward…"

Natsu shrugged. "Hey, might as well ask."

Ultear folded her arms and turned away… which naturally drew Natsu's gaze to her tight ass and shapely legs.

"I admit, I've been convinced to be more… open to certain things since you brought me here," Ultear replied, running a hand along her horn to where it parted her black hair and entered her skull. "But, frankly, I don't know you, Natsu. I know enough to trust you as a colleague, maybe even a friend, but a lover? Hardly."

"Huh," she heard him reply. "Didn't peg you for a romantic."

It seemed Natsu didn't know about her one-time tryst with Kyoka and Seilah. That meant his guild members weren't completely forthcoming with their goings-on as Hades had been with Grimoire Heart. After all, in Ultear's former guild, she'd only sprung her plan to betray Hades right as it was about to unfold, lest her lone confidant, Meredy, let it slip or inform him. Interesting.

It was at that moment which Natsu made his move, walking up behind her and sliding his hands down her arms. Holding her by the waist, he said, "So let's get to know each other."

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

"You hired us, didn't you?" Minerva asked, running her finger around the glass of wine she'd been given. "Why bother when there are so many safer, slower ways to get it done?"

In this small tavern backroom, a lonely ceiling lantern was the only source of light. She leaned forward in her chair so the light shaded the contours of her cheekbones and breasts, which rested on the table. Oh, how good it felt to be a big girl again, not simply a curvaceous one.

"No no," Minerva said, holding up her "gloved" hand. "I'll explain. You want us to do it so trace amounts of Curse power or bane particles will be left, after which I assume you'll be on hand to 'find' the evidence of your superior's black magic."

The hooded figure coughed and tore the cigar from his mouth. "How did-"

"Who benefits," Minerva said, daintily taking her glass in hand, "more than his immediate successor, who himself was more than happy to betray Fiore when it suited him? You had to be wealthy or well-connected enough to find the bread crumbs we left in the dark guild underworld so quickly. You had to have knowledge of demons to know what made Tartaros uniquely suited for this job."

Minerva took a sip, playing up the femme fatale image she'd maintained since she'd walked in. "Did I miss anything?"

The hooded figure across from her took another drag on his cigar. "Just get it done."

Minerva nodded. "Since you found us, you'll also make sure we find our payment after the bridge collapses. Immediately."

There was little talk after that. Minerva stood up and went back outside into the cold to find Lucy heel-deep in some drunkard's face. The other patrons of the wooden lodge were having a laugh at his expense, their voices carrying through the open door. Seated as they were atop short stools with large barrels repurposed as tables, Minerva saw no reason for them to think they were any better off than their punchline.

Smiling at the blonde's spunk, Minerva beckoned her to come along. Lucy released the fool and followed Minerva to the tavern keeper. After a short conversation, they each obtained a room key and proceeded upstairs.

"Why?" Lucy asked. "Don't we have things to do?"

"We'll wait until nightfall," Minerva said. "If we never leave our room, we'll have the perfect alibi."

Lucy thought about it, then nodded. Hefting her suitcase through the door, the two women found themselves in a small room with only a single bed and a table with a medium-sized mirror resting on it. An oil lamp hung from the ceiling. Was this town so poor that they couldn't afford light lacrima?

Lucy nervously stared at the bed, starting to feel like she knew where things had been planned to go. "Uhhhh…"

"What?" Minerva asked, throwing her cloak on the table and seating herself on the bed. "This tavern didn't have any larger rooms."

Which was a lie. Minerva had paid off the innkeeper to make sure the double beds were all booked, if asked.

"Oh." Lucy shrugged, none the wiser, as she parked her suitcase under the table and stretched, her cold weather clothes more accommodating to her new size. "So, what are we supposed to do until then?"

"First…" Minerva conjured a Territory sphere on the bed and crawled through. Lucy was left alone for about two minutes, staring at the swirling blue orb in the air, before Minerva came crawling back. "Natsu and Ultear will wait until the sun sets, then go to the bridge. You and I will join them and make sure they get to the other side once it's destroyed, then come back here and leave."

Lucy frowned. "Wait, so what do we do until then? The sun won't set for at least another few hours."

Minerva stood up and threw the covers on the bed aside. "I don't know about you, but I'm going to bed. I don't expect to get much sleep tonight."

Lucy nervously held up her hands. "I'll… wait, then."

"If that's what you want." With that, Minerva slid her long legs under the blankets and pulled the covers over herself. "By the way…"

She looked over her shoulder at Lucy. "I hope we can at least be friends, for Natsu's sake. We both love him, and who knows?" She smiled and rolled back over. "Maybe we can learn to share him."

It didn't take long before her breath stilled and her closed eyes were motionless. It seemed that transporting the team across several countries had worn her out.

Lucy was left alone, bored, and with nowhere to go thanks to the need to preserve their alibi. She hated to admit it, but Minerva was right. It was always good to cover her ass, which was a lot harder now that her ass had gained so much more surface area.

In the end, her boredom and need to pass the time overcame her discomfort, not to mention all the walking she'd done today. She rounded the bed, pulled the covers up, and managed to slide her back up against Minerva while allowing her gigantic boobs to rest on the mattress. Damn, did it feel good to have that load off her chest. It didn't take long for the warmth of another body and the ease of relief to send Lucy into dreamland.

Which was exactly what Minerva had been waiting for.

Opening one eye, the tigress reached out from under the covers and conjured a Territory sphere. Much like Requip Magic, Minerva could also store items and objects in another dimension. Her "personal space", as she jokingly called it. Not all things went there, as some things were better off hidden, away from where Minerva could be coerced into giving them up. This is why her stash from Succubus Eye didn't live in her space.

What did, though, was a long, black, phallic object, anemone-like tentacles flowering from its concave base. It was another, single-sided version of Kyoka's favorite toy. Except, it wasn't. As Kyoka had explained it, her toy was an Etherious demon, composed of ethernano like the demons from the Books of Zeref, but no more intelligent than a sea cucumber. It was a creature, yes, but for all intents and purposes it might as well have been an inanimate object, only awakening to feed itself with no way to reproduce. The initial creature had been carefully cultivated over decades of work, a labor of debauchery on Kyoka's behalf. Rather, it had been a labor of Kyoka's underling Lamy, now deceased, so the ability to produce more had been all but lost with Tartaros's library. Now having a better idea of how to manipulate ethernano thanks to Ravenlord's work, Kyoka and Minerva had teamed up to create a new demon rod (as Minerva liked to call it), one which need not be inserted into an orifice in order to feed or link to the user's nervous system.

Kyoka, it seemed, was more knowledgeable of Etherious anatomy than she'd let on.

Now the fruit of her labor lay clutched in Minerva's hand. Still dormant, its black tendrils were shrunken up against its base. With a finger, Minerva traced one of the huge "veins" bulging from the surface of its shaft. She had made sure to make a more veiny exterior than the first, to better replicate the feel of Natsu's incomparable schlong. Now it was time to test her toy for real, on more than just a soft hand.

Lifting the blanket up with her elbow, Minerva carefully slipped out of her bikini thong and discarded it on the floor. Her top followed, leaving her naked save for her skin-tight Etherious gloves and leggings, which might as well have been her actual skin. Her sense of touch extended to the magical material. She then put her fingers to her clit and began to rub, thinking horny thoughts. With Lucy and her plump, fertile curves beside her, it wasn't hard to conjure a fantasy. Or, in this case, a plan of action. Soon she felt the wet slickness of her lust, and so pressed the concave end of the demon rod to her crotch.

Minerva gasped as the demon rod soaked up her juices and sent a thin pair of tendrils looking for more. She slapped a hand over her mouth as the demonic toy covered her clit. It was sucking on her, while its twin feelers dipped into her honeypot like a pair of straps to get at her vaginal secretions. Her fingers joined it soon after, Minerva crossing her legs to keep from thrashing about and waking Lucy. Moments later, she gushed about the inside of her thighs.

Opening her legs, she saw that her demon rod had become a fake cock, fully attached to her smooth brown skin and solid as an oak tree. Her finger traced the line of the two feelers that were still in her pussy, but they were so flat and flush to her petals that they might as well have been ink. The other feelers spread like a flower above her, well, 'flower', with two having found the inner crease of her thigh. Oh, how she loved that crease, the way it emphasized both her supple, soft leg and smooth, flat stomach.

Looking over to the woman who slept beside her, Minerva smiled. It was time.

She rolled over and inched closer to Lucy, feeling the blanket brush against her rubber-like cock. Just like its predecessor, the demonic attachment let Minerva feel everything as if it were an actual dick. All perks, no drawbacks, though Minerva had to wonder if Kyoka could craft a demon rod capable of ejaculating. Questions for later, as she felt her tip brush against Lucy's thick butt.

Lucy stirred a little but didn't wake. Not yet. Minerva flipped her skirt up and ran a finger down the waist of Lucy's panties. Green power flowed from her finger into Lucy's body, a gift from Kyoka in exchange for helping develop her new toy. Lucy stirred a little more, her body now more sensitive. Minerva's hand slid up Lucy's back and hiked up her T-shirt. Her other hand began playing with her own nipples, getting them nice and hard.

"Mmh…" A soft sound escaped Lucy's mouth as Minerva slid her hand from Lucy's back to the side of her massive breast. Sweet heavens above, these things were amazing. So soft, so firm, but with so much mass within them. It was high time Lucy woke up.

Minerva brought herself up alongside Lucy, putting more of her borrowed Enhancement Curse into the blonde's succulent curves. Lucy moaned and started to shift as Minerva reached around and found the hardening tip of one of her nipples. Her other hand found Lucy's hair, ready, as Minerva began kissing her neck.

"Mrn…" Lucy's eyes opened up. "Min-!"

A hand clamped over Lucy's mouth as a Territory sphere deposited her Spirit Keys onto the nearby table.

"Shhh," Minerva whispered.

Lucy tore her mouth free, her breathing already heavy. "What are you doing?!" she whispered.

"Isn't it obvious?" Minerva licked the back of Lucy's ear.

"Are you…" Lucy squirmed, which only prompted Minerva to squeeze her curves harder. "Let me… Wait!"

Minerva snagged Lucy by the waist and rolled them both towards the edge, Minerva ending up on top, straddling Lucy's ass. Hot damn, it was almost as big as Minerva's S-class booty. Her dick and breasts pressed against Lucy's smooth skin as Minerva pushed the blonde's head down into the pillow and yanked her panties aside.

"Nnn!" Lucy shouted her denial into the pillow.

"You say that," Minerva said, lining herself up with Lucy's pussy, "but we both know you're strong enough to throw me off."

Suddenly Minerva pulled Lucy's hair, making her gasp as her head lurched back.

"So let's stop pretending," she said, before thrusting inside Lucy.

"MMMGH!" Lucy almost squalled but Minerva covered her mouth again. She couldn't help it. Somehow, Minerva felt even bigger than Natsu as she got started.

"Mmgh! Hmgh! Grgh!" Each thrust sent a wave of pleasure through Lucy's body, and a wave of rippling force through her bouncy mounds. Her eyes rolled back as Minerva took her hand off Lucy's mouth and hugged herself to her back, furiously fucking her pussy with Lucy didn't even care what. The pleasure was too much to resist, feeling her inner walls give way again and again under Minerva's thick onslaught. Natsu had been fiery but tender. Minerva was far more feral and lustful than Lucy's poor body was ready for.

The honeytrap of Minerva's prowess only got worse when Minerva shoved her hand under Lucy's massive breast and gave it a squeeze.

"HWAH!" Lucy had to cover her own mouth to keep from screaming. Her pussy began to tighten around Minerva's cock, its hypersensitive nerves being stroked by the hard veins she felt. She was getting tighter, tighter, mirroring the coil that was building in her loins.

"Mmh! Oh! Minerva!" Her hand fell away and grabbed the blanket. "If you! Do! No-OOO!"

Her denial was in vain as Minerva fucked her over the edge. Lucy's body convulsed as a huge orgasm rocked her senses. Two more convulsions, each paired with a wet slap as Minerva drove her on like a runaway wagon. She then released Lucy's hair and let her wind down, sliding her hand from Lucy's tit to her stomach, then below her navel. Lucy twitched; just being close to sexual contact had her excited.

"Now, aren't you glad I took your keys and pinned you down?" Minerva murmured into her back, kissing her spine with a smile. She hooked her fingers into Lucy's shirt and peeled it up her hourglass body, before tossing it away. "Could even Natsu make you cum that hard?"

Lucy's eyes widened as she realized what she'd just done. Yet, she made no move as Minerva went to unzip her skirt.

Meanwhile, back with the firebrand in question…

"Really," said a skeptical Ultear.

"Yup," Natsu replied. "She jumped out the window and knew I'd catch her. Well, I mean, my buddy Happy helped, but that's not who Lucy was banking on."

He leaned back against the boulder that was his seat rest and put his hands behind his head. "Lucy's been my girl ever since. I just didn't know it. I make her happy and she makes me happy."

"I see," Ultear said, nibbling on a piece of jerky she'd kept in a pouch that she hid under her sweater, between her breasts. She didn't know why, but she'd recently begun craving meat more than she remembered. "And you left her alone with Minerva, who, if even half of what you've said is true, is just as woman-crazy as she is man-crazy."

"Nah, Minerva's not man-crazy. At least, not as long as I'm around." Natsu motioned for Ultear to pass him some jerky. The muscle girl complied, breaking off a piece and floating it over to his mouth. Natsu, and Ultear for that matter, thought nothing of it as he bit it out of the air.

"Besides," Natsu continued, "what's the worst that could happen?"

Back at Minerva's seduction…

The demoness had counted down from 30. Round 2 was about to start.

Minerva's hand was still on Lucy's pussy, getting a feel for how much her black demon cock stretched Lucy out. Levering her arm around Lucy's haunchy thigh, she rolled the panting blonde onto her side, letting her hand slide away from Lucy's wet, dripping lips.

Minerva took a moment to admire how much curvier and meatier Lucy had gotten, now that she was dick-deep inside of her. Lucy had mountains for mounds and a smooth, hourglass curve from her waist and hips. Her tits were still her reigning feature, still so round and perky even with gravity pushing them together. Yet, her thighs had grown firmer, the contours of Lucy's muscles hidden beneath a thin layer of fluff. Her legs so smoothly transitioned into her ass, like one long heart-shaped mass of "fuck me".

On which, Minerva couldn't wait any longer. Sinking her hand into Lucy's soft skin, Minerva rammed her borrowed length back inside.

"AUGH!" Lucy's mouth had a tanned hand cover it again as Minerva resumed fucking her, her gasps and heated moans slipping between Minerva's fingers. Leaning over her, Minerva planned to stir Lucy's mind into as much of a slop as her pussy was becoming, huge gobs of femcum and pussy juice flying each time Minerva pulled back and slammed home again.

"Nnngh!" Lucy struggled to speak as Minerva's hand fell to her own, their fingers squeezing each other on reflex. "Ngh… No… S-Stop… Ah!"

Lucy cried out as Minerva pulled her hair again, exposing the side of her neck for a long, lustful lick. "You say to stop, little mouse, but you aren't trying to resist me. Is that what you really want?"

Meaty slaps filled the room as Minerva spanked Lucy with her pelvis, her own ass tightening more as she began to feel an orgasm rising. Lucy was just too fucking sexy; she'd drive Minerva into a breeding frenzy if the tigress wasn't careful.

A lustful spark of lightning flashed in Minerva's eyes. Now there was a thought: why should Lucy be the only one to be smashed into a mindless mess?

Pulling her fingers free, Minerva groped Lucy's soft breast before settling atop her side. Her breasts enveloped the side of Lucy's arm; her brown nipple kissed Lucy's swollen sideboob. Lucy was moaning and weeping with pleasure, her mouth open and tongue lolling out. Never ceasing her relentless muff-stuffing, Minerva turned Lucy's nipple up to her mouth and buried her face in the fluffy boobflesh around it, covering her whole face at once. She then reeled back and began pulling at it, sucking, daring Lucy to lactate with these gigantic melons she'd gained.

"AAAH!" Lucy couldn't stop herself from screaming as so much of her body was stimulated at once. Minerva quickly put a Territory sphere around the bed to muffle the noise a little. "Min…"

Lucy couldn't even pronounce Minerva's name as she rapidly approached her next orgasm. Pleasure was all she could think about, squelching from her abused pussy lips with each thrust. Minerva's own slit was a leaky faucet, her inner thighs soaked from how wet she'd made herself.

"What… A… bout…" Lucy's thick leg, reduced to a hip-cushion for Minerva's insatiable sex drive, began to twitch and spasm as she felt her next mindblowing orgasm approaching. Her tit felt like all the blood was flowing to her nipple the same way the rest was flowing to her loins, getting ready for the big rush. The blonde didn't want to betray Natsu like this. It was one thing to watch someone, it was another to do them.

But Lucy was powerless to resist. Minerva was a ravenous sex demon and Lucy had fallen into her clutches. She couldn't deny her as long as her body was thrashing and firing on triple the pleasure.

Suddenly Minerva stopped, popping her mouth off of Lucy's engorged nipple and drawing up. From the oil lamp above, the shadows of Minerva's curves, especially her own sizable tits, were highlighted for Lucy's viewing pleasure.

"Wha-... What?" Lucy panted. "Why'd… you stop?"

She'd missed the part where Minerva's eyes had widened. The olive-skinned woman licked her lips, but not to show arousal. Something had come out of Lucy's breast, something… Tangy. Minerva couldn't explain it. Her soon-to-be pet slut wasn't pregnant. Even so, this tasted like no breast milk she'd ever sampled from one of the many lonely MILFs she'd seduced.

However, upon Lucy's pussy twitching needily around Minerva's black tip, the tigress decided to find out in her own way.

"Because," Minerva said, "if you ever want to come like that again…" She crawled up Lucy's body, her hands sinking into the smooth layer of feminine fertility that Lucy had gained. "You need to ask."

"I… I don't…" Lucy swallowed. She wasn't out of breath anymore. Minerva loved the hesitation in her lover/victim/fuckdoll's voice. "What about… Natsu? AA-aah!"

She screamed as Minerva cranked up the Enhancement Curse and flicked Lucy's nipple. She'd gauged it just right: Lucy's pussy was still pulling at the dick tip inside it, begging to be filled.

"Natsu?" Minerva said with a smile. "We both know I'm better than him. Bigger, too, from how tight you've made yourself for me."

She gave her hips a tiny thrust; Lucy's legs tightened but once more, she didn't come.

"So what's your answer, Lucy? Because now that I've gotten a taste of this…" She slapped Lucy's ass, making the blonde yelp. Even this, though, had Lucy weeping with pleasure. "Either I get my fill, or I'll simply…" She put her brown lips near Lucy's ear. "Stop."

"Nngh, noooo…"

"No what?" Minerva spanked her again. Truth be told, keeping Lucy on edge was agony for both of them. "Be specific."

"I want you… To…" Lucy swallowed.

"To what?" Minerva's fingers trailed along the crack of Lucy's generous ass, sliding beneath her firm cheeks and teasing her other tight hole. "Be specific."

"To… Fuck me…"

"Are you sure, little mouse?" Minerva's curves settled on top of Lucy's. "Once we start, you and I aren't going to remember anything from the next two hours, just a blank slate of fucking, biting, squeezing, and cumming."

Minerva said the last word like she was tearing into a piece of meat. Which, hopefully, she was about to. "So much cumming. You'll spend every waking moment waiting for our next fuck, waiting for me to make you cum, until your whole body aches. No one else will ever be able to satisfy you."

Including Natsu, Minerva thought maliciously. Then you'll both be mine, and only mine.

"Is that what you want?" Minerva asked, extending her claws and trailing them down Lucy's side as she drew back again. The five pink lines were like beautiful maps, drawn of the contours of Lucy's body.

"It…" Lucy swallowed. Minerva could see the fear in her eyes: fear of what she was about to unleash. "It is."

"Then say, 'Please, make me cum.'"

"P-Please…" Lucy's arms slid over her giant breasts, bracing herself. "Make me cum."

"Say, 'Over and over again.'"

"Over and over again," Lucy repeated, this time without hesitation.

"Well then…" Minerva reached into a Territory sphere. Another sphere appeared atop the table near the door, from which slid a small clock. Lucy watched as Minerva's "gloved" hand emerged next and wound the clock, then clicked a switch on the back. Finally, the hand and sphere both vanished, and Lucy's eyes were back on Minerva's.

The tigress placed her hands on her own soft bosom, the blue fingers and alluring contrast to the brown skin that bulged around them. "Now watch, learn, and brace yourself."

Green power flowed from Minerva's fingers. Her chest heaved as her breathing grew hotter, heavier, hungrier. Her neck stretched as her head reared back, her body beginning to rise and fall as her sensitivity increased. It was like she was riding some invisible lover, no doubt Natsu in her mind, as Minerva's cheeks gained a heavy blush and her voice increased with every gyration.

"Ah… Hah!... Oooh!... OOH, YEEES!"

Minerva's body lurched, rocked by an orgasm. When she looked down at her blonde prey, Lucy only saw two orbs of blackened lust, insatiably ravenous for her fertile body.

"Now you're mine," Minerva growled. She dove on Lucy, and the breeding frenzy began.

"OH GOD! OH FUCK!" Lucy came fast and hard as Minerva's Enhancement Curse flowed into her. Lucy's leg was thrown aside, exposing her sensitive nipples to Minerva's own as the crazed sex maniac threw herself on top and trapped Lucy beneath her. Their hardened nubs pushed against each other, Minerva's and Lucy's boobs sliding and pressing with equal firmness of tender flesh.

"YEEES!" Minerva screamed, her eyes rolling back as she came again.

"AAAEH!" Lucy, too.

Minerva's hips rose and fell, plunging her cock into Lucy's tight snatch with a speed and power that would no doubt break the bed before they were done. With Lucy trapped and Minerva in no state to set her free, what followed was the most animalistic fuck session that either of them had experienced.

They fucked in a mating press, Minerva holding Lucy's legs back and wrapping her own around Lucy's ass, doing little more than twerking to keep as much of her stick-on cock inside of Lucy as possible. She pulled Lucy's hips against her own, the soft flesh of her legs bulging around Lucy's taut skin.

"FUCK, YOU'RE SO TIGHT! CUM FOR ME, LUCY!"

"AH, AH, AH, AH!" Lucy's tongue lolled out as they both came again. Minerva snatched it up for a savage kiss.

They fucked on the floor, Minerva seated with her legs spread as Lucy rode her in reverse. The blonde's hands dug into the bed frame as she slammed her ass down, her needy snatch sucking and salivating all over Minerva's ebony schlong. Minerva's hands weren't idle, smacking and squeezing Lucy's soft thighs while playing with her clit.

"WORK THAT NEW BODY WE GAVE YOU! EARN YOUR PLEASURE, YOU LITTLE SLUT!"

"I WILL! I AM! YES! AAAH!"

Minerva grabbed her huge tits and pulled herself against Lucy. It hurt to have them grabbed so hard, yet even this made Lucy cum herself silly.

They fucked against the wall, pounding against the sturdy oak until it began to crack. Minerva's hands were on Lucy's ass, holding her in place as she smashed her into the wood while fucking her asshole with another dildo, this one non-magical. Lucy's fingers clawed at Minerva's back, screaming into her shoulder with every climax they shared.

"MIN-! NER-! VA-!" The poor girl wanted to scream her mistress's name in euphoric rapture. Too bad Minerva was sucking Lucy's voice out of her left nipple. There was no doubt: something was coming out of Lucy's tits. Whatever it was, it was keeping Minerva's fire going well past the point where she would've burned out. She was giving Lucy everything she had, but Lucy seemed to be giving it back somehow.

The tigress of Tartaros smiled up at her blonde victim, then sucked hard and scraped her teeth on Lucy's pink skin.

"NO! TOO MUCH! HAH, AH, UUUGH!" This was her biggest orgasm yet, every spasm forcing a syllable of gibberish from Lucy's sore throat. She'd been screaming her lungs out for practically the entire time, Minerva never giving her a rest. The combined mass of their humongous breasts sloshed against their bodies as they kissed again, eyes rolling back as even this wasn't the end of their wild coupling.

What brought it to an end, finally, was the clock Minerva had set. Having fallen on the floor at some point, probably when Minerva had used the side table to seat Lucy upon while she devoured the blonde's smooth pussy, the clock began to chime.

Minerva, drenched in sweet-smelling sweat despite the cold climate, paused in her relentless pussy-grinding and allowed Lucy's leg to slide from her chest.

"What… Is that?" she panted, out of breath but hardly exhausted. Beneath her, with her legs open for a tried and tested girl-on-girl position, Lucy's only reply was a gurgling groan. Her mind had long checked out; all that was left was a broken mess of orgasms and the desire to reach them.

"Hah… Ah… One more," Minerva said, folding Lucy's leg back up and lowering her pussy against hers. Minerva had at some point lost her cock, the appendage unable to hang on amidst Minerva's bottomless sex drive. It had rolled under the desk, slick with femcum, which hadn't stopped Minerva from switching gears.

"Oh… Kay…" Lucy panted, before Minerva kissed her, bunched her boobflesh up in her hands, and rubbed them both to a final climax. Lucy's hands slid along Minerva's smooth skin, pulling on her jiggling ass as she drew rings with her swollen clit. Ten seconds later, the two women screamed into each other's mouths, their legs pulling each other close. They wanted to savor the feeling of their bodies, melting together like chocolate. Of course, Lucy had a lot more body than Minerva thanks to her giant boobs, but neither one of them cared.

Her clarity returning, mostly because her appetite had finally shrunken a little, Minerva retracted her Enhancement Curse. Both girls slumped and lay limp, Minerva's cheek resting against Lucy's. Both looked at the clock, lying sideways as it continued to chime.

"Oh well," Minerva sighed, turning Lucy's head to give her one last kiss on the lips. "Next time, little mouse, we'll go even longer."

Lucy nodded dumbly, staring up at her new mistress with her golden locks lying splayed about the floor. Her huge mounds remained bunched up against Minerva's, bulging and relaxing with her steady breath.

Minerva smiled wickedly. "Say, 'Thank you, mistress.'"

Lucy slowly nodded again. "Thank you, mistress."

Minerva's blue-coated hand ran along the underside of Lucy's jaw. She loved how Lucy turned into it like a cat, aching for her touch. Now, Natsu would only get his new girlfriend if Minerva let her off the leash. It was a leash she planned to keep tight, because she liked the idea of owning the busty blonde.

Not co-owning, like with the rest of the harem. Lucy was all hers, which meant one less woman she'd have to share Natsu with.

Ultear's hands roamed over Natsu's body, their lips locked as they felt up the other's muscles. His body heat was a nice contrast to the cold mountain air surrounding them, nipping at Ultear's pale flesh. Her sweater lay spread on Natsu's seat-rock, along with Natsu's vest and scarf.

He was hot, in more than one way, but Ultear had seen plenty of sexy men in her time. She'd even traveled with several, both as a member of Grimoire Heart and later with Crime Sorciere.

She broke from the kiss to let him take a hands-on feel of her breasts, her sky blue lips curling into a smile.

"I still can't believe you're the same person I fought on Tenrou," she said.

"That's just it," he replied, before putting his forehead against hers and grinning. "I'm not."

Hell no he wasn't. Ultear shuddered as Natsu once again whispered to her of his "reckoning", as he'd called it. He'd reckoned that the client might doublecross them. Thus, Ultear would need to rebuild the bridge. He'd reckoned that he or Ultear might be recognized, due to their past involvements with the Magic Council. Thus, a missing Sabertooth mage, plus a small-time reporter, would make for better contacts for their client to meet.

And he'd reckoned that if he left Minerva alone with Lucy, his scheming nymphomaniac of a partner… "Queen", maybe? She would find a way to put the moves on Lucy. That was why he'd given Kyoka his permission to share her Enhancement Curse if asked. Between what Minerva had told him of her lust, and how she'd been eye-fucking Lucy the moment that Lucy had finished growing, Natsu had no doubt that Minerva would be all over Lucy with that new toy she'd been secretly working on with Kyoka. Minerva probably thought that was a secret, but Kyoka was far too loose with her tongue when Natsu used his tongue.

And, knowing Minerva's prowess, not to mention her level of stamina, he'd reckoned that Lucy would be completely comfortable with Minerva by the time they were done.

That's why Ultear was horny for him. What Ultear rarely saw, and what turned her on like no other, was a sexy man who was smart, underhanded, confident, but most of all empathetic. In her time as a dark wizard, that last trait was hard to come by.

"All part of my plan," Natsu explained, "to make sure everyone in the guild likes each other."

"And was kidnapping me part of your plan?"

"No," he admitted, then swept his hands along her indigo leggings, "but I'm glad Minerva did it."

Ultear ran her hands up his chest and put her lips near his ear. "For that, we should thank her when we're done here."

To Natsu is Awesome for suggesting Lucy be given magical lactation. That single suggestion opened up the door to new mechanics of body molding being explored and explained, Natsu's new anatomy getting some worldbuilding attached to it, not to mention Lucy's MILF transformation.

Now I feel I should ask: what do you think of everything, readers? Of Minerva's budding power play? Of Ultear joining the guild and being given a new lease on life along with a new body? Should the next chapter be more plot or more "plot"? Should Tartaros's next batch of recruits come from the Avatar arc, the Dragon Cry movie, or perhaps you have someone else you'd like to see abducted and turned into a demon?
