[Femboy TF, Hypnosis]

"Well well. You're a sight for sore eyes, Gorgon. What brings you into my workshop?"

"I need your assistance, Medea. You are the only one that could possibly help me. And I know that you'll aid me, considering you have the same issue that I have. The very same problem that's plaguing me and driving me close to madness."

"Ah. Yes. A shared problem of ours. I suppose I do know something like that... It wouldn't happen to revolve around our dear Masters, would it?"

"It would."

Standing within the Caster-class Servant Medea's personal quarters were two Greek legends. Medea herself, who was currently clad in the cloak that kept her identity hidden, as well as the much larger and almost towering serpent Gorgon. Both of them had experienced a lot of scorn throughout their lives, but they came together for one reason and one reason alone at this point.

"Then I suppose you need my help to make sure that you can have him all to yourself?" Medea said, her eyes gleaming out from underneath her hood. "And why should I help you with that, considering I want him just as much? You really think I would be the kind to extend an olive branch to a rival, knowing what I've done?"

Gorgon shook her head and softly smiled, which only served to make that smile that much more foreboding. "I know that you'll aid me. Because this is the one chance you'll get to have an ally in your cause. For however long you'll be able to keep your possessive elements in check, I will be there to ensure that we gain what we both want. Our Masters in the palms of our hands, free from the prying eyes of any other female. Especially that girl who's been by their side since the moment their journey started."

Medea paused and laughed as the larger snake saw right through her, prompting her to pull down her hood and expose her elegant blue locks. "Very well. Then I suppose we'll have to act quickly. There's no way that we'll be able to plot for long without somebody realizing we're working together, so I believe we should go for a quick and decisive way of dealing with all the girls that catch his gaze."

"My Mystic Eyes should do the trick then." Gorgon said, her soft smile turning wicked as the power started to pour from those eyes. "As long as I can keep my eyes on them, I can turn them all into statues. There's no way that he'd find a way to love a statue."

Medea shook her head. "No. To truly make him ours, we need something a bit more." She explained, as she picked up her Rule Breaker, carefully dragging her finger along the edgeless side of it. "We need to upgrade your Mystic Eyes. Using them, we'll be able to disable all of the girls that stand in your way. Not just by turning them into statues, but by making them utterly undesirable. And as an added bonus, they'll be much more useful in their new forms. You want that, don't you, Gorgon? To have obedient slaves at your beck and call, whenever you need them?"

Gorgon immediately started rapidly nodding. Maybe a bit too enthusiastically. But she desperately wanted this. She had been away from her Masters for too long. Disposing of the obstacles in her way using this method was more than acceptable, if it meant that she wouldn't have to be away from them for much longer. "Whatever means we need to take, I trust your judgment. As long as you do not turn that power on me. If you do, I'll ensure that you'll end up humiliated by the new form you take."

"Oh, don't worry. I don't intend to get in your way. I know better than to get in the way of love." Medea said, as she stuffed Rule Breaker into her cloak. She'd need it soon, especially if things went wrong. "Now, bring your eyes down here, so I can make sure that the magic that pours forth from them is the right type."

Gorgon listened, carefully lowering her head as Medea started to cast the spell that would make these Mystic Eyes so much more...

---

"Gorgon? She wanted to apologize for what she had done to the Masters back in Babylonia? That's a first."

"Indeed it is, Da Vinci, but I can't help but worry. She is still an ancient Monster, after all. I can't help but feel a natural sense of worry pour through me as I look at her, especially when she tries to act apologetic..."

"Don't worry. That's exactly why I'm here. If anything goes wrong, you contact those two and make sure he gets here in time. He's the only one that can make her calm down, should anything bad actually come to pass."

The two Servants that were currently busy walking down the halls of Chaldea were some of the Masters' closest confidants. Leonardo Da Vinci, the Caster-class Servant that kept track of the shop and ensured that everything was properly running whenever they needed special equipment, and the Shielder Demi-Servant, Mash Kyrielight. And while they were definitely willing to give Gorgon the benefit of the doubt, they couldn't help but be a bit worried. Of course they would, they were both talking about the same woman that had nearly put an end to one of the Singularities on her own. Before everything turned sour after her defeat...

And that was the event that Gorgon wanted to apologize for. Apologize for when she was being possessed by Tiamat's spirit. Apologize for how she had terrorized everyone. To say that it was hard to imagine that she would actually give them that apology was an understatement, but those two always told them to give people the benefit of the doubt, no matter if it would result in them betraying your trust. Because it would somehow always turn back around.

With a deep breath, Mash pushed open the doors leading to the cafeteria. Which was currently empty aside from two very menacing ladies. Indeed, just the sight of the two of them was enough to put the purple-haired Shielder on edge. "Gorgon, you didn't say you'd bring somebody along to spectate. I thought you wanted to apologize to us."

"I did say that, yes. And I was entirely sincere. I just wanted Medea along to serve as a neutral party." Gorgon said, carefully resting her elbows on the table she was currently sitting at. "Is there a problem with that? Or can you bring forth our Masters, so they can listen to this as well?"

"There won't be a problem, Gorgon." Da Vinci said with a soft smile as she stepped closer to the table, resting her gauntlet-covered hand on the backrest of the chair. "We were just curious. You're not going to interfere or cause problems, right, Medea?"

Medea nodded, softly smiling as she had her hood down. "Don't worry. I've had a long talk with her. She actually came to me for advice. I suggested that this would be the best way to mend the damage that had been done by your initial meeting." She explained, before softly leaning back. "You both need to listen to her. I'm sure that you'll find that she truly is sorry about everything that she's done."

Mash was still not certain. In fact, Medea backing her up just made it all that much more suspicious. But she didn't want to look like she was just on edge for no good reason. She exhaled and sat down on one of the chairs, looking straight at the serpent that had caused her so much harm. "I trust you, Gorgon. So please, don't drag this out. Let's hear your apology, and then..." She paused, before smiling a little softly. "We'll treat you to dinner. That should make up for our dodgy behavior. Right, Da Vinci?"

Da Vinci grimaced slightly in response. Mostly because she remembered what happened the last time she had to help cater to somebody for a special event. It was... Not a disaster in and of itself, but the aftermath of the meal was horrendous to manage. That was why they made sure that none of the younger Servants would get involved. Goodness, just thinking about those events made her blush...

"Thank you." Gorgon said with a soft smile. But that smile was just so foreboding. Despite the clear kind intent, it just felt wrong when it came from somebody so obviously evil as her. "Now then, I do wish to apologize. Sincerely, from the very bottom of my heart."

Both Da Vinci and Mash listened as the serpentine Avenger started to apologize. Yet there was something wrong with the way that she started to trail off as she looked at them. What was she thinking of? She wasn't planning on trying something, was she? She should've learned from the last time she lost if that was the case. They'd both find a way to overpower her...

"I apologize. Because you two really are the biggest idiots that I've ever met!" Gorgon shouted as her eyes suddenly started shining bright pink, as if she was activating her Mystic Eyes. And yet something was wrong. Something was very wrong...

And neither of the two girls were able to do a thing to stop this wrong feeling from permeating through them as they were forced to look into those eyes. They weren't being petrified, that much was certain. But it wasn't like their current sensation was much better. It was like something rock hard was being pushed into them. Something strong, something thick, something that was making it harder and harder to think.

Medea smiled as she watched the two girls writhe. It seemed like the magic had done its job. It was a bit of a crude spell, truth be told, but that didn't mean that it wasn't working. If they had to take out their competition in a fast and efficient manner, this was definitely one that she would pick. One that would completely and utterly eliminate any chance of them getting in the way...

"W-What's happeningggg?!" Mash cried out as the intensity inside her kept building. It was making her hotter and hotter. Forcing its way through her as it was getting harder and harder to stay still. It was like something was thrusting into her. Something hard and thick...

Da Vinci was much the same way. Thrusting her hips forward as she used the chair as support, all while her frame slowly but surely started slimming down. The gauntlet on her arm fell off to reveal a much more feminine arm. But at the same time, it was clear that her arm didn't actually belong to a girl. It was a masculine parody of a female arm, to the point where it was even more exaggerated...

It wasn't just her arm either, and it wasn't just her that was experiencing this kind of slimming. Mash was also getting slimmer in all the feminine spots. Her chest and her hips were both being pinched closer until they were as narrow as they could be. All while moans upon moans were pouring out from her and Da Vinci's lips.

To say that they were girls at this point would be plainly wrong. They both looked like feminine boys that were wearing their respective outfits in such an improper fashion. The clothes just didn't fit on their frames. Whether it was due to their slightly wider shoulders, or the way that their bodies had slimmed to the point where the rest just didn't fit inside the armor or dress very comfortably, or because their respective panties were now between their thighs...

A moan left their lips at the exact same time as they forcibly thrust forward, all while a few droplets of thick white liquid started to squirt onto the ground below. Their feminine aspects had been completely and utterly erased in a matter of moments, and their bodies were now completely and utterly male. The cum drooling from their brand new cocks being all the evidence one would need to get to that conclusion.

"S-So h-hard..." Mash cried out as his hand immediately went down to his brand new shaft, gasping and panting. It was such a tiny thing, and yet it was so terribly sensitive to the point where he immediately orgasmed as soon as he put his fingers onto it. His eyes were already rolling into the back of his head as he thrust his hips forward helplessly as he came again and again.

Da Vinci wasn't much better off. In fact, he was positioned in such a way that he could thrust his tiny cock right through a tight hole in the chair, which was just tight enough that it wouldn't hurt him, and yet it would still pleasure him in such a way that he couldn't possibly endure it. Which meant that he naturally started to hump away at the tiny hole in his chair, which let him cum over and over and over.

Gorgon let out a bit of a grim giggle as she watched what was happening. It was actually astonishing to see how effective her brand new Mystic Eyes were. They were still made for petrification, but they petrified the feminine gender. Which served to then leave them irrevocably male, and with their bodies completely and utterly unable to handle something so simple, they became little more than horny femboys that couldn't do anything except for hump and hump away.

But that wasn't the only thing that she wanted out of them. As they kept on cumming, her eyes started to beam images into their head. Images of her. Images of her visage. Reminding them who had blessed them with their current state. Reminding them who they should be focusing all of their attention towards.

Da Vinci was the first one to end up falling prey to the images that poured through his mind. Gasping and panting and trembling as his mind fell victim to the overwhelming assault. "G-Gorgon! Mistress! GODDESS!" He cried out in such a needy fashion as he thrust harder and harder with every image that filled his mind. He wanted her. He needed her. He needed her to tell him that he was doing a good job. That was the only way that he was going to be able to overcome this need inside him. But at the same time, indulging in this need would only make it stronger. Which meant that he was now caught in an overwhelming loop that would leave him as little more than a needy but obedient femboy that would do anything for his Goddess.

Mash tried to resist. Well, partly. The memories of his Masters, his Senpais, was an incredibly strong. But it wasn't going to last. Not for long enough. Those memories were quickly being pushed aside by the new hotness inside his mind. That large serpentine woman who was practically kissing him with how close she got whenever those images beamed into his mind. It made his cock tremble more and more, which made him masturbate more and more. "Mistressssss! MISTRESSSS! MOOOOORE!" He cried out in need as he came again and again into the palm of his hand. Forcing him to let out more and more of that sticky white juice, with no real end in sight as he almost grew limp from how much he managed to cum.

Medea softly clapped as both of the femboys were reduced to helpless cumfountains. "Well, that's two. Seems like all you'll need to do is let your eyes gaze into theirs, and their bodies will be made into your toys. I'll admit, the spell worked better than I expected, but we're getting closer to our goal of having them as ours and ours alone." Medea said, a soft smile on her lips as she eyed the oversized serpent beside her.

Gorgon nodded as she licked her lips. Seeing those boys cum again and again, all because of their new devotion towards her... It was giving her strength. She could take on anybody. Even her Masters, should she want to make them her toys... No, she shouldn't. Even with this much power, turning them both into useless femboys would ruin their charm. No, she needed somebody to test her powers on, somebody strong...

"What's the meaning of this!? Gorgon, what have you done!?"

"Aha, looks like the old snake's up to no good again! But don't worry, we're here to make sure you're down for the count before you ruin things again!"

And Fate decided to deliver two delicious morsels right on a silver platter. Bursting into the Cafeteria, after they had heard the sound of extreme eroticism pour through the halls, were the Berserker-class Servant Raikou and the Rider-class Servant Quetzalcoatl. Two powerful women that served to protect the Masters from anything that might bring them harm, while at the same time taking on a maternal and protective role for both of them.

Gorgon smiled as she watched the two come in. All while she briefly looked down at Medea. "Stay there, Medea. I will make short work of these two. For interrupting our experiment, and for getting in the way of our plan to have our Masters all to ourselves!" She shouted, climbing over the table and knocking both of the obedient femboys down in the process. She didn't care much for them. What she was interested in was just disabling all the competition that was getting in her way. And those two women, those two infernal women, they were some of the ones that would serve as her greatest obstacles if she didn't get rid of them now!

Medea slowly pulled up her hood as she grinned. Oh yes, she would stay behind. Because what came next would serve to show her just how powerful those eyes were. And if they were as powerful as she thought they'd be, then she would have to take action. Gorgon just had to play her part, and then the rest would unfold as she had planned...

Raikou drew her blade as she glared at the oversized serpent. "What have you done to them, Gorgon? What have you two been doing in here?! What were all the noises that poured out from this room? Answer me! NOW!" She shouted, as her fury started to increase. She was going to carve this serpent to pieces, just like she had carved through the Oni that served Shuten Douji..!

"You really should answer, Gorgon." Quetzalcoatl smiled softly as she started cracking her knuckles. "Because you'll find that I don't exactly play nice when it concerns keeping my Masters safe. You wouldn't like what I'll do." Her soft smile turned into a wicked and almost fight-hungry grin as the muscles on her body started to bulge. She wasn't about to back down. In fact, she was probably going to piledrive Gorgon through the floor before she'd even think about giving up...

Gorgon laughed at the two womens' attempts at seeming threatening. But all she had to do was let her eyes flash forward, and then the power of her Mystic Eyes would do the rest. Especially since neither of the two were prepared for what she might do to them.

Indeed, neither Raikou nor Quetzalcoatl realized what was happening before it was too late. Both of their bodies trembling as the pink glow from Gorgon's eyes started to reflect within their own. And they were both forced onto their knees in an instant, the sheer intensity of the pleasure spiking through them simply overpowering them at their core.

Raikou was hit most of all. Due to her natural absurd mindset that came with being a Berserker, the sheer intensity of the pleasure pouring through her was too much. Especially as the rock hard shaft, or at least what felt like one, suddenly shoved its way into her rear. She was forced to thrust her hips forward in response to the brand new pleasure inside her, gasping and panting as stabbed her blade into the ground to support herself in any fashion.

Quetzalcoatl was a bit more resistant. Mostly due to her divinity giving her some sort of edge over Gorgon's influence. But even that didn't last. She was just as vulnerable to being changed like this. Her muscled body grew nice and slim and weak as she cried out more and more, cumming violently before she had even finished transforming as cum started to pool between her thighs.

And by the time that Gorgon's eyes pulsed once again, neither of them could even come close to stopping the final growth. The growth of their brand new manhood, which simultaneously caused their tits to flatten against their chests. They were both now flat femboys that couldn't do a thing except thrust forward. Even if their minds were still ever slightly intact. Their bodies had fallen to the kind of pleasure that would be utterly impossible to fight against.

Indeed, Raikou had fallen even further. Because as soon as his mind was starting to fill with Gorgon's imagery, his nature as a Berserker started to melt together with the images. He was meant to be a mother, but he was definitely seeing a proper matron inside his mind. Which meant that she had to be his mother. And she was the most beautiful mother that he had ever seen, the mere thought of her, the mere sight of her figure driving him to climax more. "M-Mother... M-Mommy..! Mommmyyyy!" The converted femboy cried out with desperate need as he appeared even more desperate than before, his cheeks flushing bright red as he imagined what it would be like to be completely spoiled by one's dear mommy.

Quetzalcoatl was falling just as quickly. But instead of falling because he was imagining what it would be like to be spoiled, he was falling because he could practically feel Gorgon's tail coiling around her. Even though the version of Gorgon that was currently busy cooking his brain with all sorts of horny imagery hadn't used her tail to move around, the fallen femboy definitely remembered what it was like. How it felt to have it squeeze around him and show him exactly who was supposed to be in charge. It was an overwhelming sensation that was utterly impossible not to think about, moan after moan leaving his lips while his body made it seem like he was busy being squeezed. It felt so fantastic. So utterly wonderful..! "Harder, Mistress...! HARDER..!" He cried out, all while his pathetically tiny cock continued to spill so much cum out that it was almost impossible for him to fertilize somebody as it quickly turned nice and clear...

Gorgon laughed as she watched both of those powerful women fall complete and utter victim to their own delusions. All she really had to do was just look into their eyes, and they became nothing more than her horny and obedient femboys. Just like what had happened to Da Vinci and Mash! They were completely and utterly neutered in the grand scheme of things. Nothing would stop her from doing the same to everyone else at this rate. Nobody! Not a single person would be able to stop her.

And it was all thanks to Medea for casting that nice little spell on her. The spell that allowed her Mystic Eyes to petrify the female gender. She had to thank her. And maybe subject her to those eyes as well, because there was no way that she was going to share her Masters with her. Even if she had helped her, she wouldn't even think of sharing somebody as precious to her as those two with somebody as wicked as her. They were going to be hers and hers alone..!

"Medea!" Gorgon shouted, as she turned to look towards the Witch that had helped her. Only to notice that the Witch had seemingly disappeared. All while she was busy turning those girls and women into nothing more than femboys. "...Strange, she was right there, wasn't she? No matter, if she's decided to tuck her tail between her legs, then she will just have to fall victim to these eyes at a later date. She'll be just like them once I'm done with her. Utterly devoted to her Mistress... No, to his Goddess!"

"You really think so little of me. But that's why I came prepared." Medea said as she appeared right in front of Gorgon, at a range where the oversized snake couldn't just look down at her and immediately transform her. And in her hand, she held a dagger that was not unlike the Rule Breaker. This one glowed pink, just like the serpent's Mystic Eyes. "Let's see how you feel when you end up just like them, Gorgon! GENDER BREAKER!"

With her impromptu mock Noble Phantasm, Medea pricked the dagger right against Gorgon's crotch. And in an instant, an overwhelming sense of pleasure poured straight through the oversized serpent as a bulge grew from that very same crotch. A bulge that very quickly consumed every little aspect of that feminine area, turning it into nothing more than a femboy's pitifully tiny cock just like what had happened to the other girls that had been affected by Gorgon's eyes.

Gorgon was struck by so much pleasure that she couldn't possibly comprehend what was happening before it was far beyond too late to do anything. In fact, thanks to her crotch being the first thing to go, she couldn't stop thrusting into thin air thanks to how sensitive her brand new cock was. It was so intensely sensitive that she fell onto her knees immediately, bringing her down to Medea's level as she could practically see the Witch gleefully and sadistically leering at her. Not that she could do anything to stop her. Her hips were already doing so much work that even trying to focus on somebody or something other than her cock was pointless.

Of course by having her gender broken in the same kind of way that all of the other femboys had, most of her femininity and even her dominance vanished just like that. Her massive breasts, her wide hips, everything just collapsed and left her as a femboy that wasn't even tall enough to look into Medea's eyes. Even the power that the Witch had given her disappeared, leaving her as nothing more than a horny boy that couldn't help but thrust forward.

"H-Haaahh... S-Stop, stop..!" But unlike the others, Gorgon was still able to keep his mind. Ever so slightly. He could understand what had happened to him. How he had been betrayed. How he had been completely and utterly betrayed by somebody that he had allied himself with. Even though he was the one that was going to betray her first. That thought didn't even cross his mind at this point, he was too horny and too incensed over the betrayal to worry about the consequences of his own actions.

Medea smiled. And she just pulled her robe aside to reveal her own pussy. The single piece of femininity left inside this cafeteria. "Lick." She gave him a single command, her voice reverberating through the femboy's mind. So much so that she could see the resistance fading from his expression. Fading away as his eyes grew nice and glazed and obedient.

Gorgon wanted to disobey. Gorgon wanted to tell her that he wasn't going to do what she told him to. But he couldn't. There was no way that he could go against Mistress. Mistress' cunt looked so delicious. So much so that he immediately started to latch onto it, licking and slurping away at those meaty lips as he did everything that he possibly could do to satisfy her. All while his cock kept on drooling out more and more of his cum. Cum that contained more than just his seed that could be used to impregnate somebody...

That cum, as well as all the cum that had been drooling out of the cocks of all the other femboys, was directly tied to their feminine selves. The more that they came, the more the process became irreversible. They wouldn't be able to return to their female selves if they ended up cumming too much. But did that truly matter, when they were having the time of their lives enjoying all of this?

Gorgon would disagree. It didn't matter. Especially not as he ate out his Mistress. As long as he satisfied her, he would be rewarded. And he would keep cumming, and he would get the chance to please her all over again. That was all that he needed. Even though he didn't realize that it was an implanted cycle that he was a slave to, he didn't care. He just wanted to cum and cum and make Medea happy.

Medea let out moan after moan as that eager femboy made sure to make her feel good. So good that she ended up falling on top of him, burying his face between her thighs while using him as a seat, all while he just kept on eating away at her pussy. It was so overwhelming. But it was so worth it. Even if he wasn't her Masters, even if he wasn't as horny as they were...

He was enough to satisfy her. He made her cum, causing all of that feminine juice to squirt all over his face. Which in turn made him thrust upward as his cum drooled out of his cock, the white gunk having turned completely clear from the sheer excess that had been fired out.

The afterglow washed over both of them, but Gorgon didn't stop. Cumming, for the most part. His mouth couldn't move because his face was currently being pressed far too tightly by those two thighs...

All while Medea softly laughed, sighing as the warmth overwhelmed her. It felt so good to use him. And it'd feel good to use all the others. Now that she had proven that the power that she had blessed Gorgon with worked, and how she had repurposed it into another Noble Phantasm, she could claim her Masters for herself...

But first, she'd make sure that she had used the boy underneath her for all his worth. Unaware of the pink glow from the jagged dagger laying by them, and how it was starting to reflect inside her eye...
