Maka Albarn had been following Nygus for some time now. They had left the Infirmary, where Tsubaki was still raw-dogging the newly-female Black Star, and had descended down a staircase in the Nurse's building that Maka had never seen before. The place was dimly lit, candles lighting and extinguishing along the walls as Maka and Nygus descended the stone staircase. They were deep underground now, they could no longer hear the rutting, animalistic noises Tsubaki and her pet continued to make.

"Miss Nygus, where are we going?" Maka asked as the two continued to descend.

"I have a special section of the building reserved for your… unique problem, Maka. Don't worry. We're almost there." Nygus replied. And sure enough, moments later, the two had reached the bottom of the stairs. Before the women were two massive stone doors, snakes carved into them, coiled and ready to strike. Maka hesitated, the last time she'd dealt with snakes it hadn't been pretty. She and her partner had nearly died thanks to Medusa. Her partner… what was his name again? For some reason, it all seemed a blur. Maka was still lost in thought by the time Nygus had pushed open the stone doors to the wide, circular room within. Stone basins lit up all around the room with purple flame, bathing the room in violet light.

Before the women were machines of various intent and size, most of which Maka Albarn couldn't determine. Some looked like exercise machines she'd seen at the gym, others were completely foreign to her, or out of place, like a fireman's pole in the center of the room, a pool, and other mechanisms. Nygus looked Maka right in her eyes.

"Maka. From here on out, everything I instruct you to do is for you, for your dream of being with Crona. Do you understand?" Nygus asked.

"Yes." Maka said.

"Do you trust me, Maka?"

"Yes."

"Good. Now, follow me. And whatever you do, you must follow my instructions exactly. Don't do anything unless I tell you to." Nygus led Maka into the strange, violet-lit room. Despite the fires lining the wall, the space felt abnormally cold. Maka could feel her hardening nipples rubbing against her sports bra. While Maka Albarn was nowhere near well-endowed enough to wear a "real" bra, she still wore one for modesty and support. Right now though, she wished she wasn't. Soon enough, Nygus brought Maka to a plush chair made of crushed velvet and black leather. Maka and Nygus were about a foot away, but even at that distance, the chair radiated heat, some sort of high-intensity seat warmer clearly engaged. The heat danced at the edge of Maka's flesh. She so desperately wanted to sit, but Nygus hadn't instructed her to. Instead, here Maka stood, frigid, her rock-hard nipples digging into her bra. If only she could sit! Nygus looked the chair over, and then examined Maka. She did so slowly, deliberately. Maka was shaking from the cold.

"N-Nygus… may I p-p…"

"Ah, no speaking unless spoken to." Nygus said, and Maka immediately clammed up.

"For our first act, we'll try some visualization exercises. You may sit, Maka." Nygus said. Maka took one step forward before Nygus stopped her.

"Shoes and socks off, Miss Albarn. I wouldn't want you getting dirt on the upholstery." Nygus instructed. Maka nodded and did as she was told, unbuckling her shoes and taking off her dark socks in a hurry. Maka's bare feet stood upon the cold stone floor, sending shivers up her spine. She looked back at Nygus. The nurse nodded.

"Now, you may sit." Nygus said. Maka practically threw herself at the large, plush chair. The instant she sat upon it, warmth flooded her body, as if she was a child coming inside from a long day out in the snow. Soon enough, the warmth was overwhelming her, and she began to sweat. Maka moved to stand up, but was quickly rapped with something hard across her knuckles. Nygus was holding a riding crop, one Maka hadn't noticed before.

"I didn't tell you to stand." Nygus said, rather coldly. So, Maka sat, sweating in the bizarrely hot seat. Maka was shifting in her seat, drenched in sweat. She recoiled in surprise as a collar suddenly landed in her lap.

"Now, put that on." Nygus instructed. Maka turned the collar over in her hands. It was made of black leather, with a heart-shaped gem at its center. The gem was a deep red, like a ruby, but glinted with flecks of deep purples and blacks. Maka was no fool – this was clearly enchanted somehow. However, the heat was making her thoughts hazy, and her hands still stung from Nygus' last punishment. So, Maka obeyed without a word. She pulled at her red necktie, undoing it and tossing it to the floor, popping two of her top buttons off as she did. Sweat pooled around her clavicle and down to her breasts as she placed the collar around her neck. As soon as Maka positioned the collar, it sprung to life, and snapped closed around her windpipe.

"Gah!" Maka cried, the sudden pressure taking the wind out of her. The girl's thoughts were hazy. She was barely conscious, her body awash in heat and her brain losing oxygen. As she writhed in the plush seat she was forced to sit on, Maka saw Nygus put a collar around her own neck – a collar identical to hers. Nygus groaned as the collar gripped her neck, but soon grew accustomed to it. Nygus' eyes flashed a neon pink. Unknown to Maka, so did hers.

"Maka… you're going to die if you don't do exactly as I say." Nygus said, practically towering over the young girl. "Imagine. Imagine your lover, the one you're fated to be with. The one you desire most." she said.

"C-C-C…" Maka croaked, barely able to speak with the collar against her neck.

"Yes?" Nygus sneered, her cruel face obscured by the bandages across it. She put a hand to Maka's chin.

"Say it." A fire filled Maka. A burning, passionate need. The gem in her collar blazed pink and she cried out.

"CRONA!" Maka yelled. Nygus faltered backwards, the gem in her own collar glowing bright pink.

"Yes… I see him…" Nygus moaned as images of Crona's monolithic body flooded her mind. "That body… that power…" she said, raising her arms up. Maka was too lost in her own lust to notice that the sleeves of Nygus' nurse uniform were wriggling, convulsing under the strain of something just beneath the surface. The light on Nygus' collar had spread to her skin, neon pink veins coursing from the collar and spreading over her bandaged body.

"Your need… your lust… I can feel it!" Nygus moaned as she clenched her fists and brought her arms down into a double bicep flex. Her arms responded, quivering and rippling under her nurse's uniform until suddenly they exploded outward, shredding the sleeves as her once lithe arms gave way to dense, corded muscle. Nygus' biceps swelled over and over again in time with her heartbeat, throbbing with thick, powerful muscle. Her forearms engorged, her nails turning black. Nygus moaned in pleasure as her still-flexing arms began to lengthen, growing until her knuckles touched the floor. It was an unbelievable sight. Nygus had grown two alpha python-like arms, each nearly as big as her body. Her biceps measured 35 inches around, veins spreading across the massive peaks as she flexed.

"So… this is his power…" Nygus said, heaving with hot, heavy breaths.

"His… power?" Maka asked, barely able to think straight. She was so constricted by the collar that she couldn't think straight. But she saw Nygus, and her huge, meaty arms. They reminded her of Crona. Maka wondered just how those big fingers would feel inside, and began to lose her composure. The gem on Maka's collar surged with pink light again, and Nygus' gem shone with it. A wave of pleasure wracked Nygus' body and her arms seemed to move on their own, almost as if in a trance. In one swift motion, the nurse tore her gown in half, leaving what remained hanging on either shoulder. Maka had a clear view to Nygus' black lace lingerie, and soaking wet panties. Then, Nygus' arms began to move – jerking this way and that, as if not under her own power. Her hands shifted robotically, her massive fingers plunging underneath her panties and into the dripping sex below. Nygus cried out – her new fingers were bigger than anything or anyone she'd had before, and she was loving it.

"Ah! Ah! Ah! Yes! Fuck!" Nygus moaned, losing all composure. She finger-fucked herself hard, feeding her pussy as much as it would allow. Nygus was so lost in pleasure that she hadn't realized how off-balance her new arms made her. The nurse's legs were practically convulsing under the strain of the new weight suddenly thrust upon them, but Nygus didn't care. She just kept going, fingering herself over and over with an enraptured look on her face. Her muscles were screaming, bones creaking – her whole lower body was begging her to stop, but Nygus paid no heed. Then, just when Nygus' legs were about to break, they exploded with bronzed, gleaming muscle. In an instant, Nygus' legs went from their normal, lithe form to a beastly 50 inches thick each. Her quads were practically bursting with corded muscle, her calves bulging. Her demure slippers had been obliterated, leaving her large, bare feet exposed, her toenails a deep black. Not only that, but her legs had lengthened in conjunction with her arms – Nygus was now six and a half feet tall! It was like looking at a mismatched Nubian goddess. Maka was at a total loss for words.

"Not HRRGH quite AHHN right!" Nygus cried as she continued to finger herself, love juices pooling on the floor beneath her. Nygus began thrusting her hips forward, in time with her own ministrations. The creaking of fabric on skin made Maka realize what was happening – Nygus' ass was expanding. Maka couldn't see, but Nygus felt her ass balloon outward, forming perfect, watermelon sized orbs.

"GRRRRRAAAAAH FUCK YEAH!" Nygus screamed in ecstasy as she came. Between her furious fingering and the massive expansion, Nygus' panties had had enough. The soaking, black lace panties exploded off of Nygus, and landed right on Maka's face. Maka's senses were flooded with the scent of Nygus' sex. All Maka could think of was how good it smelled, how badly she wanted it. Before she even knew what she was doing, Maka was sucking on the panties, lapping up the juices still stuck to them.

"More… MORE!" Maka moaned, and her collar glowed in response.

"Yes…mmh…YES!" Nygus roared, her collar glowing as well. In no time at all, Nygus' body began to change again. Her arms convulsed, and in an instant, her arms were farther apart. Another shake, and her arms were further apart again. Her shoulders were widening with every twitch, straining her already nearly destroyed nurse's uniform. Not only that, but with every pulse her shoulders grew denser, more powerful, capped with muscle. Nygus' dress was approaching its limit. Fabric began to tear as Nygus' body thickened, losing its feminine hourglass form in favor of a masculine, thick v-shape. Her stomach swelled, to the point that she might have appeared nine months pregnant were it not for the Amazonian state of the rest of her body. Nygus seemed to regain some sense of composure as she drank in her growing torso. She took her hands out of her needy pussy and put them behind her head. Nygus turned, facing away from Maka. She flexed, hard, and her back began to pulse.

"Rrgh…RRAAGH!" Nygus yelled as her muscle bloomed across her back, developing into peaks and valleys like the wings of an angel. When it was done, her dress was finally in ruins, the tattered cloth falling to the floor. Nygus turned to face Maka again, looking proud of her newfound body. But she wasn't done yet. Nygus squatted down, and flexed – hard. Maka was still sucking on Nygus' panties, enjoying the show the whole time.

"HRRRGH… GRRRRRGHH…" she growled, bestial and low as her body responded. The fat in her stomach quaked and shifted, redistributing itself equally around Nygus' new torso, though special attention was given to her breasts, which ballooned from an already large DD cup to a G cup in a matter of seconds. Her lace bra exploded, and the pieces hit Maka, who grabbed them hungrily. She wasn't thinking – all she wanted was more pleasure. Maka took the torn bra and rubbed it against her pussy, eager to mingle her scent with Nygus' own.

While Maka pleasured herself, layer after layer of pectoral muscle swelled in Nygus' chest. The fat redistributed as the pulsing muscle growth continued, until Nygus had two massive, meaty pectorals that extended out almost a foot beyond the rest of her body. They jiggled as they adjusted to their newfound size, far bigger than her old breasts. Nygus was drooling. She wanted so badly to fondle her new chest, but her changes were not yet finished. Her stomach gurgled and groaned as fat and muscle shifted, molding her pot belly into a chiseled, bulging eight-pack. Nygus sighed – her transformation was nearly complete. She spied Maka, paralyzed in the plush chair and sucking on panties. A devilish grin grew across Nygus' face. She was going to wrap that girl right around her not-so-little finger. Nygus strode up to Maka like a perfect runway model, and strattled her massive legs across Maka's lap, her hot, steaming sex hovering right over Maka's. Maka was squirming, throwing a mindless temper tantrum that she couldn't feel Nygus' heat against hers right away as she continued to pleasure herself.

"Mmph! Mmph!" Maka moaned through Nygus' panties.

"There's something you should know about these collars, Maka." Nygus said huskily, leaning over the small girl. "They feed off of lust. They give your partner the body you want – the body you need. But, they were recalled. You see… if you break the collar…" Nygus explained, trailing off as her traps bulged, packing muscle in time with her neck, which was rapidly beginning to strain the collar she was wearing. Nygus leaned in to whisper in Maka's delicate ear.

"The effects become permanent." She revealed. Maka was drooling, lusting over the beefy body before her.

"Is that what you want, Maka?" Nygus asked as her traps bulged and expanded as her neck grew thicker, cords of muscle rising to the surface as she spoke.

"Yes…" Maka moaned through Nygus' lingerie.

"Is it… what you need?" Nygus asked, tracing a large finger around Maka's mouth, scooping up some of her drool and putting it to her own mouth.

"YES!" Maka screamed. Nygus' neck doubled in size at the surge of lust, her collar straining to keep itself attached.

"Oh… silly me…" Nygus said, "I forgot the most… important… thing." she said. Nygus felt a shift in her loins as her transformation reached its final stage. Her exposed, soaking wet pussy sealed up, all by itself. Then, the fused labia began to swell, and sag. The pouch began the size of two clementines, then two apples, then two full sized grapefruits, newly formed testes aching with seed. Nygus squatted down further, letting her balls touch the chair. The hot, steamy sack was pressed right into Maka's inner thighs. The warmth of them, after such an absence of it in this hidden place, was a welcome relief for Maka. Without a second thought, she wrapped her legs around the ball sack and let every bit of its heat take her.

"Yes, Maka! YES! FUCK, here it comes!" Nygus cried as her last vestige of womanhood, her clit, began to squirm in response to Maka's lust. It grew rapidly in length, snaking its way under Maka's clothes, until it reached an unreal thirty inches long, reaching up into Maka's blouse. The flesh around everything but the head of Nygus' clit began to thicken, creating a long, veined shaft. And finally, that shaft began to thicken. Maka was in heaven, seeing Nygus' cock inflate under her own clothes, it's girth barely contained by the buttons of her blouse as it reached its final width of four inches. Maka had subconsciously been inching her body closer and closer to the cock as it had grown, so by the time it had finished, the head was peeking out the top of her blouse, and Maka's legs were firmly cradling Nygus' new balls. Maka felt the heat of Nygus' cock, the pulsing of her heartbeat through the throbbing member. She realized then that she was face to face with Nygus' massive, newly formed cockhead. Maka let Nygus' panties drop from her mouth and took in the musk of Nygus' manhood. Gods, she even smelled like Crona. Maka was hornier than she'd ever been in her life as she noticed the cock squirm and writhe under her blouse. A slit appeared at the head, the newly formed urethra, which let out a glut of precum, coating Maka from her clavicle to her chin. It was so warm. So good.

"Hello gorgeous." Maka whispered to Nygus' cock. "Welcome to the world." she said. Maka wasted no more time, and showered Nygus' member with frenzied, slobbering kisses. The stimulation was all too much for Nygus, who in no time at all, howled in pleasure, and came for the first time with her new cock. The sheer force of Nygus' cock tore Maka's clothes away, and showered her in cum. Nygus experienced one final tense of her newfound muscle, and the collar around her neck snapped. This was who she was now. No going back.

Nygus showered Maka in cum, and there the two remained for a time, each drinking in the other with mutual lust. Finally, Nygus spoke again.

"Excellent. Well, Maka Albarn, if you truly want to please a body like mine, we still have work to do. Are you ready for your next lesson?" Nygus asked.

"More than anything." Maka said. And she meant it.
