[Sluttification, Bimbofication]

The sun was shining. The waves were billowing. And everything seemed perfect on this hot summer day. At least that's how it seemed, though there were probably a few that would disagree or even raise a couple of questions.

"Rin, why are we at the Beach? Without Shirou, even?"

And the King of Knights, who had managed to keep her presence within the modern day, was one to raise such questions. Accompanying her former Master and her current Master to London was nothing too difficult. No, what really ended up raising her eyebrow was the kind of activities that said current Master dragged her out for. That girl, when brought out of a pressing situation like a Holy Grail War, had a real bad habit of getting wrapped up in shenanigans.

"He's busy with his studies, and Sakura's visiting! What better way to catch up than to enjoy a trip to the beach? Isn't that right, Sakura?"

Tohsaka Rin was acting far cheerier than she had any right to. Especially while showing off her body in the way that she was. She was wearing a nice black and red bikini, though while it was nowhere near as tight up top as it probably should be, her bottom was practically begging for release. While there were certainly rumors in the Clock Tower about her defenseless ass, perhaps it'd be better to call it a danger to any kind of underwear...

"Ehe... I didn't think you'd ask me out like this, Rin. But I guess it's a good idea. Besides, we can always pick up Shirou later."

Matou Sakura, who had gotten over a lot of her problems with Rin through grueling and difficult battles, was now smiling right beside her. Unlike her sister, she wore a one-piece swimsuit that had white and purple hues, which instead emphasized her breasts due to how big they were and how much they pushed against the fabric. Which had already started to draw attention towards the group.

"I'm glad you two are enjoying yourselves, but I feel like this is awfully flimsy reasoning." Artoria muttered as she quietly looked around. Compared to the two long lost sisters, her swimsuit was a bit more modest. White with a hint of blue near the edges. And her figure, due to her natural training, was a lot more toned than theirs were. So while she drew attention, it was less due to her natural sex appeal and more due to the fact people couldn't believe a girl like her could be that toned.

Rin laughed, a little bit of sweat running down the side of her head. "It's fine, it's fine! We're just going to enjoy ourselves, maybe get a little tan. Nothing bad's going to happen, I even made sure that Luvia wouldn't be here to mock me over my bikini!" Mentioning Luvia's name caused her to twitch. That finnish girl had been such a thorn in her side ever since she enrolled at the Clock Tower, so she really didn't want to think about her too much. Even just mentioning her was like setting off a small firework inside her.

"Luviagelita..? Oh, her? But Rin, she told me that she pitied you and your lack of fortune. Why, if you got down and begged on your knees for forgiveness, she might just hire you as a maid and deal with your finances for the foreseeable future!" Sakura said, a soft blush on her cheeks. "I certainly wouldn't be against that idea, having you serve me while I'm enjoying tea with her."

Rin flushed bright red. "You shouldn't listen to her, Sakura! She's just trying to fool you into thinking that I don't have any money! I have plenty of money, and I'm sure we can make even more money while we're here! So don't you even dare think that she's right!"

In that moment, she let a little too much slip. And it prompted Artoria to glare at her Master. "Rin. The reason you brought us here. Tell the truth. Now." She knew a bit too much about Rin's money making schemes... Because more often than not, they resulted in complete chaos. Which resulted in either her getting humiliated, or everyone getting dragged down alongside her.

"I don't know what you're talking about." Rin tried to play coy, before she saw Artoria enter an aggressive stance, which prompted her to quickly throw her hands up in defeat. "Alright, alright, I need to pay off some debts and I heard there was going to be a contest on this beach that promised a ton of cash, so I thought we could all join and make our chances of winning even bigger!"

Sakura let out a soft 'ooooo' as she realized what she had been roped into, while Artoria just sighed in response. "Rin, you should know better at this point. Who even told you about this contest?" She could already tell that things were about to get a lot more difficult. She should've just stayed home and helped Shirou out with his studies.

"Oh, just a couple of boys from my class. Luvia backed them up, and as much as I loathe her, she has some amount of authority with regards to our fellow students. So it has to be legit." Rin narrowed her eyes for a moment. "Though I'm surprised we haven't seen her, if she really thought that this was legit."

As Rin started to think a little more critically about the situation at hand, the three saw a darker-skinned man approach them with a big grin on his face. "Hey there, ladies. You looking to be part of our contest? You three look damn sexy, so I'm sure it'd be a treat for everyone involved."

"S-sexy? I-I mean, I guess..." Sakura muttered, a little bashful. Well, if somebody else thought that she was sexy, then surely her Senpai would think the same of her. Ah... If only he could've been here.

"Ehehe. What's the prize looking like, big guy? We won't participate unless we've got a chance at something real nice." Rin played hard to get. While at the same time doing absolutely nothing to conceal her greed. All while Artoria continued to quietly roll her eyes at the idea of any of this going well.

The darker-skinned man let his grin widen in turn. "We'll get you everything you want if you end up the most popular girl in the contest. How's that sound? You girls up for the challenge?" He wasn't phased by her greed, any girl that wanted to take part in the kind of contest that he was hosting had to be at least a little greedy.

"Sign us up, we're ready for anything!"

Artoria just shook her head in shame as she watched her Master agree to something so obviously dangerous, prompting her to pull her aside as the darker-skinned man walked away to handle a bit of the paperwork. "Rin. I don't know if you noticed, but I could smell the Mana leaking off him. He's bad news. We should go, before we end up caught up in something dangerous."

"It'll be fiiiine, Saber. Just relaaaaax." Rin brushed Artoria's worries aside, grinning as her eyes very clearly showed her greed by having her irises turn to Yen for just a few seconds. "We're going to win this no matter what. You heard what he said, we're real sexy. I'm sure we'll win the contest with ease!"

"You didn't even ask him what the contest was about." How did it come to this? Why was she the voice of reason? Artoria had to wonder, while casting a glance towards Sakura. "Sakura, surely you must think that this isn't a good idea. Please. Help me talk some sense into her." She truly did hope that Sakura would be her salvation in this case, even though she knew that she could be just as unreliable as her sister.

"I think it might be fun." Sakura said, shooting down Artoria's hopes in the process. "Come on, Saber. It'll be fine. We might even have something fun we can tell Shirou once we get back home. I think he might enjoy a story or two about our time with this contest." Being called sexy had definitely stopped her from thinking straight.

Artoria let out a mildly frustrated sigh before nodding. "Alright. You win. But if anything goes wrong, don't blame me. I warned you both." She relented. She really didn't have any faith in all of this, but fighting against both of them would just result in her getting a headache.

"Then let's gooooo! What's the worst that could happen?" Rin cried out, running into the distance to join that handsome man that had invited them to join his contest. She was going to win everything that he had on offer. And then she was going to make him get her as much money as she needed, ehehehehe... Maybe a bit more than that...

Sakura ran after her sister, with Artoria right behind her. All while the blonde kept thinking about how all of this was definitely going to go wrong. It was just a matter of how and when.

But how wrong could it truly go..?

---

The contest was definitely not off to a good start in Artoria's eyes, as they were each given a white t-shirt to wear on top of their bikinis. Because as it turned out, the contest was all about making those t-shirts as wet as they possibly could get, just so they could show off their curves underneath the soaked garments.

"I knew it was going to be terrible. I just didn't think it'd be this kind of terrible." Artoria muttered as she looked at herself. The t-shirt was... really, really light and thin. Like it was practically going to dissolve once it had been soaked in water. Which meant that you'd easily be able to see their breasts underneath... Not that it was actually that humiliating since they got to keep their tops on, but still...

Rin tugged on the t-shirt a bit, shrugging her shoulders. "It's not thaaaaat bad, Saber. It's just a little bit of water. How's that going to hurt you?" She said, though she was starting to have a few doubts. Mostly in regards to how the contest was going to pan out. How were they going to truly show off their sexiness if they just got soaked? And how was that going to win her the prizes that she craved?

Sakura frowned a little as her breasts pushed out against the shirt. "It's barely even covering anything already..." She muttered. Getting wet really wouldn't do much in her case. You could already see her cleavage due to how thin the shirt was and how weak it was. If it got drenched, then it might just get stuck inside her swimsuit. But at the same time... "...Is that what it means to be sexy in this country?" A very valid question, considering how she had barely spent any time in England compared to her sister.

"Definitely. Don't worry too much about it. You too, Saber!" Rin chimed, before stretching a bit. "We just gotta get splashed, and then we'll show everyone else how sexy we are. And then... Well, we'll get what we want. It's simple!" She truly believed in what the man had told her. No matter how bogus it could be.

Artoria resigned herself to her fate as she walked out of the changing stall, giving the 'contest grounds' a brief scan. Honestly, it was just an isolated square of the beach with a couple of other males in the 'audience', and... Not a single other girl there. It stank to high heaven of being a scam. "Rin, don't you think it's weird that there aren't any other girls?"

"That just means we win immediately!" Oh, the thought of winning had Rin riled up even more than she already was. "Come on, let's show our stuff and get that cash!" She didn't even try to hide her greed as she rushed out, Sakura following behind her. Which left Artoria to quietly walk over to the podium that she had been assigned.

As far as the darker-skinned man had told them, they had to stand on these three podiums. And once they were ready, they'd be blasted by water until they were completely and utterly drenched. From there, the judging would begin. And once they had found a winner, they'd get the chance to ask for anything. They'd make it come true, no matter how impossible it seemed.

It was completely and utterly suspicious. And of course Artoria could do nothing to stop them. She just stood there, with her arms hanging by her side, waiting for it all to begin. If anything truly did go wrong, she could easily call upon Excalibur and deal with the people that were behind all of this. It wouldn't be difficult. It'd hardly make her break a sweat. She just hoped that it wasn't a trick, because everything made it seem like it'd be a trick.

Sakura stood on her own podium as she blushed from all the men looking towards her. Goodness, was she supposed to feel this tense with all these eyes on her? Was this how her Senpai felt when he was busy showing off his magecraft in front of a critical audience? She didn't know, she just knew that she felt a little shameful. They were looking at her thighs, her breasts... definitely magnetized to her breasts. How many of them were peeking deep into her cleavage from such a distance..? She couldn't tell, but she could definitely make out a lot of dirty glances like that...

"I bet you like what you see!" Rin grinned, as she invited them all to look at her. Of course she wanted them to look at her. Showing off like this was what she needed to do to win. And if Sakura and Artoria had to lose, then that's just how it had to be. She'd win, she'd get her cash, she'd get Luvia off her back... It was all perfect, she just had to win this silly contest through nothing but her sex appeal. And if there was one thing she had, it was sex appeal. Sure, she wasn't as endowed or as toned as Sakura or Artoria was... But she knew how to use what she had, which was why she slipped her thumb in between her bikini bottom and her ass, letting the string snap back into her thigh after she tugged on it a little.

The men focused their eyes on her, though not for long. The same handsome darker-skinned man that had invited them to take part in his content made his way over to the podiums, grinning while hiding his eyes behind a pair of thick shades. "You three look even sexier with those things on. So, I guess you're all ready to begin? Or do you need a little more time before we get you girls soaked?"

"We're as ready as we can be! Right, girls?" Rin grinned as she looked at her sister and her Servant. All while showing them that she was confident that she'd beat them. The grin on her face said it all.

"Mmhm. We're ready, Mister. Make us as wet and as sexy as we need to be, so we can win this contest!" Sakura was just as confident that she'd win. They had called her sexy, so of course she was going to win.

"Ready." Artoria said, as she kept on scanning her surroundings. If they really did have something planned, she was ready to stop it. All for the sake of the two other girls, who she would protect with her life if need be.

The darker-skinned man grinned. "Then let the Wet Slut contest begin!" He said, snapping his fingers... And activating the magecraft that he had planted around the podiums, which quickly started to send out highly pressurized streams of water!

"Wet Slut-" Artoria immediately picked up on what was about to happen, but her reflexes completely failed her. She was slammed by the jets of water, letting out a soft moan as her t-shirt very quickly ended up getting thoroughly soaked by it all. She should've seen this coming, she knew that it would happen. And yet she still got hit!

Sakura let out moans as well, though it was more due to how utterly sensitive her body was due to how it had been trained. She let out moan after moan as her shirt got completely soaked, while those jets kept on firing at her most intimate areas as well. Her crotch, her ass, and especially those massive melons got some special attention from those magic streams.

Rin joined her sister in letting out moan after moan, trembling all over as the sheer amount of water splashing against her was more than a little much. Especially as the streams kept on smashing against her ass more so than her t-shirt, making it harder and harder for her to react because of how sensitive that rear of hers was. No matter how much of a danger that ass posed towards her bottoms, it was still painfully weak to anything else...

All three girls were being completely and utterly drenched, and the men in the audience cheered as they watched it all soak in. Because not only were their t-shirts getting so soaked that it was incredibly easy to gaze through the wet fabric, but the magic properties of the water were making short work of anything that was keeping them modest underneath all of that.

It didn't matter what kind of bikini or swimsuit they were wearing. All three ended up completely naked aside from the t-shirt they wore. Which really didn't give them any sort of modesty due to how absolutely thin the fabric was. You could easily see their nipples poking their way through that nearly invisible garment, all three of them moaning more and more as they were being splashed with so much water that it was getting a little difficult to keep track of.

Though that was entirely by design. The idea with the contest wasn't just to get them soaked. It was to soak them so much that they'd end up letting the magic into them. And from there, it would lead to them getting even easier to play with. Which was especially evident by Artoria's expression, which had gone from tough and protective to one that was filled with bliss. And it was all thanks to the magic soaking into them.

It wasn't Water magic. Or at least, it was merely a conduit for it all. And the results of the magic soaking into them was easy to see, especially as Artoria's muscles gradually started to fade away, with more and more emphasis being brought on her other assets...

Of course she wasn't the only one that was affected by the water being blasted at them. Sakura was experiencing just as dramatic a shift, though it was less in terms of her body growing less capable, and more in the form of her already excessive bust getting even bigger. Bigger, better, and bouncier. So bouncy in fact that it just kept on bouncing as the water splashed against it more and more, not even close to being restrained by the jets of water.

And it felt so good. It was like something was being washed away inside her. She wasn't quite sure of what, because all the water splashing against her felt really good. She just knew that she liked it and that she wanted more of it. She wanted so, so much more. She wanted to get so soaked that she'd forget everything, just so she could enjoy the feeling that much more.

Her sister was experiencing the same kind of rush, though her growth was much more focused on the junk in her trunk. With all the water splashing against Rin's butt, of course those buns had started clapping. And the more they clapped, the more the magic soaked into them, and the more they grew in turn. All while she was panting and gasping and moaning like mad.

It felt so wonderful. Her confidence in this entire contest allowed her to act on her desires, as she put her hands behind her back and just helped bounce that butt of hers around. Twerking in time with all the water being blasted at it. She had honestly completely forgotten all about the contest, and right now she just wanted to let all of that pleasure soak in so she could have so much more fun.

All three girls had lost themselves to the pleasure that was being poured into them by the water. All three had started to lose a lot of what made them so strong in each their own way, with their sexualities being emphasized instead. Whether it was Rin's ass, Sakura's tits, or Saber's overall curvature. All three of them were like exaggerated bimbos, swallowed by the onslaught of all the fun they were having.

But eventually, the water jets stopped. And the three girls were left completely and utterly drenched, unaware of their sensibilities carefully pouring down them. Both in the form of sweat that had been leaking out while they were being blasted, and in the form of juices pouring down their thighs. They just stood there, gasping and panting like a set of whores, as the crowd cheered them on despite the fact that they weren't aware of what they had been doing.

"Well, well, well. We really can't pick a winner after that performance, can we?" The darker-skinned man, who was definitely a magus considering what he had set up, grinned as he got close to the three sluts on the podiums. "So, girls. What do you want? You're the winners of the Wet Slut contest, so you just have to tell us and we'll make it all come true."

He didn't really get a response from any of the three girls. It was clear that their minds were currently occupied by all the pleasure pouring through them. Which just made him laugh, because it showed that he had done a damn good job of rinsing them out. Honestly, who had told them about this place? Weren't they aware of the beach's reputation? Ah well. He got some new sluts out of it, so he shouldn't really complain.

"C'mon now, girls. Surely one of you might want something." The culprit said, before letting his thumb slide under his waistband and gently tug it down, just so the three of them could catch a glimpse of the black slab hidden within. "Maybe some of this? I'm sure sluts like you could do with a good cock."

Artoria and Sakura immediately noticed the faint outline of the darker-skinned man's shaft, drool working its way out of their mouths as they could barely wait for a chance to slobber all over that thing. But it was Rin that took the initiative, grinning as she climbed off the podium and squatted down in front of that handsome hunk, pulling his shorts down with her teeth while giving him a real slutty look as she did so.

"Iiii... Want..." She mused, right as that massive slab of thick black meat very nearly slapped her in the face once it was released from its comfortable prison. "As many cocks as you can give me... Ehehehe..." All of her restraint, all of her pride, everything that kept her from being a common slut had been washed away. And when a slut like her was faced with a cock this sublime, of course she couldn't resist.

"As you wish."

A single snap from the culprit's fingers, and the men in the audience were more than happy to lend those girls a hand. Of course, their idea of help involved getting real nice and cozy with the contestants.

Rin got exactly what she wanted, once she had made her wish. And that was having plenty of men, each of them nearly as hunky as the man that had invited her to the contest, pull out their shafts and let them rest in front of her. Just looking at them was making the magic inside her run wild, her lips plumping out into a pair of red puckers while her hair turned nice and blonde like a proper bimbo's should.

As she launched kiss after kiss, she continued to look the part. Bigger ass, a little more up top to make sure she didn't end up too unbalanced, and such long hair that it looked like she had been a bimbo for ages. When really, she had only just started getting to know all these cocks in front of her, and how wonderful it felt to launch kiss after kiss onto them.

Sakura got a taste of the same sort of pleasure as one of the men let his fingers sink straight into her obnoxiously large melons, letting her moan like the slut she was. Just the moan itself was enough to make those lips pop out and grow nice and full, letting her look the part of a bimbo before her hair turned the same sort of blonde as her sister's...

Having such a strong hunk of a man play with her really helped accelerate her bimbofication, especially as a couple more of them approached and let their shafts push up against her tits. So naturally, as she already caught up in all the pleasure that her tits brought her, she was more than happy to service them with a little help from the man that was still gripping those tits... Mmph, it felt so nice to play with them all...

As a delicious bit of irony, Artoria was perhaps the one that had fallen the most out of the three wet sluts. She was already blonde, so her hair just grew extra long as she got down on her knees when faced with all of these delicious looking shafts. They made her mouth water, which only served to emphasize her plumped up lips.

She let them have as much fun with her as they possibly could. While she gave some of these cocks the kind of love they deserved from her tits and her lips, the men that wanted a little something more could go ahead and have fun with her holes below. Anything to make sure that she kept on enjoying this pleasure rushing through her, satisfying the needs that had started to grow within her.

None of the three girls were anywhere close to the same kind of girls they were before. All of their natural pride and restraint had been washed away. And the more they indulged themselves, the more they ended up looking like they had belonged on a beach like this all along. Had they ever even been anything but babes that loved to party on the beaches anyway?

As far as they were concerned, after soaking up all that magic from being splashed with water and getting their new lustful appetites satiated... Nah, they really weren't anything except for a set of horny beach babes, letting those nice big hunks play with them as much as they possibly could. Nothing else really mattered to them. Just the sensation of being used as playthings. That was the real fun of it all...

So when they all ended up reaching the point where they couldn't take it any longer, the climax that washed out between their thighs marked the final few moments of their former selves. Rin, Sakura and Artoria would never be the same... And they honestly didn't care.

Because right now, the only thing that mattered to wet sluts like them... Was enjoying all the cock that these hunks could give them...

---

"I wonder where the three of them went..."

Emiya Shirou had finished his studies some time later, and only after having done so did he realize that something was very weird. Namely the fact that the two girls in his life, as well as his former Servant, had all but vanished. And so he headed to the one place he thought he'd be able to find them, considering he had heard so much about their presence there.

And yet he couldn't really see them. He thought he'd be able to, because he definitely wouldn't be able to mistake Rin, Sakura and Artoria for anybody else. They stood out so much, especially in this country. So he really was surprised to see that he couldn't find them...

"Mmmmph... What a cute guy. Wanna have some fun with him?" "Whatcha think he'll like? My tits or your ass?" "It doesn't matter what he'll like, as long as he plays with all three of us..."

But they found him. Or at least, the bimbos that they had become did. Before he knew what happened, he found himself grabbed by three exaggerated blonde babes, each giggling as they held onto him. "Can I help you?" He didn't even pay attention to their sensual bodies, more just looking them straight in the eye. "I've been looking for these three friends of mine, so-"

Shirou didn't get to finish before the bimbo that had been Rin forced her lips onto his, with the other two bimbos kissing him on the respective cheek. And in that single moment, they washed away all his resistance, the sheer potency of their bodies more than enough to overpower somebody like him. Especially since they were still filled with so much horny energy that they were practically walking aphrodisiacs...

In a way, he did find them. Not that he'd realize it. Not that he'd return home satisfied. No, they decided that he was cute, and since they really wanted to stuff their pussies full and satisfy their needs. So the wet sluts did what they did best. They made love to the man they loved, even if neither party was truly aware. All while Shirou got dragged into the same spiral of pleasure that they did...

With his skin tone darkening until it was the same hue as the man that had converted the girls into sluts...
