Shirou couldn’t even believe it.
One day, just as he had been making his way home after a long day at class, that bastard Zelretch had appeared out of nowhere, and with one swift move he had gone ahead and sent him away from Fuyuki City. Shirou had totally been bothered by how the perverse man must be planning something, yet there was no way for him to even figure out what his scheme was… because he’d been sent to another world. Fortunately enough, he hadn’t been sent to ancient times, be it the Middle Ages, or Mesopotamia. The world into which the young man had been sent into was not that different from his really, everything almost seemed the same.
Including the fact there was magic in that new world, even if it worked quite differently from what he knew. Another thing that had happened when he was sent into that new world was the fact he changed, not too much when it came to his mental state, but rather on the fact that his body had gone from that of a young adult into that of a young… runt, which only made Shirou further wonder what that damn man had been thinking about when expelling him. However, there was quite a good benefit from his new look, as just doing the cute-act and putting on some puppy-eyes was more than enough to get him in the good graces of any girl that came along his path, and had been of enough help to make him settle in Kouh Town.
One thing that also wasn’t that different from how things were at home was the fact there were SOOOOOOOOOOO MANY FUCKING HOT BABES! Every single moment of the day, he’d be crossing paths with hotties that totally had the best bodies ever, FUCKING ROUND AND HUGE ASSES AND WOBBLY TIDDIES that truly were the stuff of legend. That was something he fully took notice of when he met Rias Gremory, and the redhead girl truly had blown his mind away by how much of a fucking sluuuuuuuuuuuuuuuuuuut she was! It was almost as if she was the main character of some ecchi-fueled series, and that only made his stay in the new world much easier for him to adapt. And she wasn’t the only girl that made him act like stupid, as Akeno Himejima too was such a fine hottie that made him think of Sakura and her absurd tiddies.
And he couldn’t forget about Koneko Toujo, that fine, adorable girl truly was even more intense than Illya in her desire to have some shameless debauchery and then some! Which was also matched by the sheer, obscene lewdness that Asia Argento could show when given a chance to showcase her horny urges. Sure, the blonde girl maybe wasn’t as FUCKING THICC as the others, but she had more than enough drive and enthusiasm to push him to the limit, making him cum some absurd loads of sperm!
Of course, the chesty babes were enough to make him wanna unload every single time, and once he discovered the academy they were enrolled in, he hadn’t wasted his chances and he had made a move to also find a way to join Kuoh Academy, which had been quite the easy thing when the Student Council had some nice bitches such as that Xenovia girl. Just by adding the perfect mixture of cute and horny had been enough to push that bad slut around, and after sucking off his cock she had totally ensured he became a student!
There were some weird stares from other students, many not being convinced at all that this new transfer student was seventeen years-old. But nevertheless the way he acted and carried himself in school definitely seemed to fit that description. The female students in particular quickly took a liking towards him for his cute size and face accompanied with a genuinely mature personality, while there were quite a lot of students at the Academy that caught his eye, he did make sure that on the surface he appeared calm and rational still after all.
However, it wasn’t all just good lewd fun with the curvy girls that caught his attention, at some point or later, just like back in Fuyuki City, he found himself involved in all sorts of strange, supernatural-related messes. Not involving the great heroes of old in the Holy Grail War or anything of the sorts, but instead, demons, priests and even fallen angels! And to make it all the more surprising, just like in Fuyuki, he soon discovered that all of the attractive women of this town he had met were all also involved in these supernatural incidents!
Luckily, he still had access to his abilities as a Mage, even better, they appeared to be significantly stronger in this new world for that matter. Back in the world he came from, Shirou’s Tracing Magecraft was severely limited in both power and efficiency, it proved useful for him in clutch of the battles he was forced to go through, but ultimately even he was aware that it was something of an useless skill for a Mage to have, not that it bothered him however as he had no interest in pursuing a life as a Mage, his Magecraft was moreso a tool he could use in direct combat, which is what was actually important to him as someone that aspired to be a “Hero of Justice”.
And now, in this new world with demons and angels and the likes, the extent to which his Tracing Magecraft could be taken was so much wider! He didn’t understand why exactly, probably something to do with the nature of this world, but he was now able to materialize weapons he never could have before, and with a quality identical to the originals! Even weapons of great divine and demonic power! And even with the scope of them, he no longer had to materialize his Reality Marble to materialize dozens if not hundreds of weapons at once.
With this massive boon, Shirou found himself, through a series of many contrived events, fighting toe to toe with none other than a fallen angel. All to protect a girl with glasses and a strange magical girl-esque outfit. He successfully managed to ward off the enemy, and that is when he got the invitation. The girl he had just saved was Sona Sitri, and her older sister, Serafall Leviathan, had given him the invitation to come to her castle for a visit as personal thanks.
Shirou truly couldn’t believe it.
------
Serafall Leviathan, like many of the girls at Kouh Town, had become interested in Shirou ever since he joined the academy, and if anything she had been wondering about his potential. Not only was he cute enough, but she had managed to see him in action after a certain battle, and the way he uses his magic to create swords both holy and from demonic origin had made it clear enough that she needed him! Oh yes, the way to create weapons that went beyond any human control was perfect, and she really desired to possess his power.
The question was, how to get control of him? She can’t use a potion or any trick she knew to make him a blind follower, because everyone else would soon take notice of any strange attitude he would take. Certain mind-control potions were far from perfect, and the last thing she wanted was to get either Rias or Akeno to suspect all of such nasty tricks being her work. “Oughhhhhhh! i WANT EMIYAAAAAA! I WANT HIM! I WANT HIM!!” The magical girl thought as she was making her way home for a new day of classes, and she was truly wondering what could be the best plan out there.
Just as she recalled that one time she caught Rias and Shirou having some odd… fun at a karaoke, however, she began to notice something. Shirou enjoyed being around girls quite too much, especially if they had some nice round backsides and FUCKING FAT TIDDIES! As she walked across the streets, she was wondering if maybe she could put good use to her body? “Nahhhh! That’s to gross! No way I’d ever do such a thing!” The girl said, as she was truly not believing she could ever think about using her own looks to such use. Of course, she wasn’t bad-looking, not at all, but she wasn’t the type to act like an obscene slut like Akeno or even the Student Council girls! Oh no, she was never going to act like such a crass hussy, she knew way better than that!
Just as she was about to cross the street, however…
“W-WATCH OUUUUUUUUUUUUUUUUUUUUUUT~!!”
Serafall barely had any time at all to react, as a rush came right towards her, and then… CRASH!
The wanna-be magical girl fell all over the floor, and she grunted as she couldn’t believe how someone had dared to crash against her! “Oughhhh! W-What the…?!” The girl groaned as she was totally not prepared for what had happened a few moments ago, but as her eyes went down to see who crashed against her, her eyes went SOOOOOOO FUCKING WIDE as she just now realized who it was…
On top of her, there was none other than Shirou Emiya, and her heart began beating faster as she was totally not believing it! She had been thinking about the red-haired runt the whole time, and she had him right before her eyes!
“Ah, my apologies!” The redhead said, quickly extending a hand towards her. It took a bit for her to respond as her mind processed that he was right then and there.
“Ah, t-thank you!” She said, taking his hand and clinging into it as she got up from the ground.
“Are you okay?”
“Yeah… I’m fine…” She looked him in the eye, this was the perfect opportunity. Something that felt like fate itself serving up what she wanted right there for her on a silver platter. She just had to make the move. But she had to be careful with how she approached this.
“Say… I think I recognize you… you’re Emiya Shirou! Aren’t you?”
“Uhm?” Shirou was surprised to hear his name being called out like this. “Yeah, I am, why do you ask?”
For some reason, Serafall found herself licking her lips before she replied. “Well, I am Serafall Leviathan, and I know you helped out my sister when she was in a pinch.”
“Your sister?” Shirou was initially confused at what the girl in front of him meant, before his mind began rewinding back what had happened the previous week, and he remembered the girl he saved. And with this, it also came the realization that this twin-tailed girl in front of him was just like Rias and the others, someone involved with all of this demon stuff. “Oh, I did, yeah… I couldn’t just stand there, I felt like I had to do something when she was in danger.”
“Yes… she was very grateful to you when she talked about it…” She smiled as she said. And Shirou couldn’t help but realize she looked nice, a pretty face, the big twintails sort of reminded him of Tohsaka, and while not the bombshell on the same level as the likes of Rias or Akeno, her body was very far from bad, including a rack he sure wouldn’t mind rubbing his hands all over if given the chance.
“I see… well, I’m glad she’s doing okay…” He blushed a bit, putting up a bit of a mature, respectful boi act. While his new body was annoying in how so many couldn’t believe his actual age, it did lead to making a nice impression like this becoming much easier.
“Yes… and I’d like to know the savior of my little sister a bit better…” She said, now leaning a bit closer, trying to make herself just about ten percent more seductive without making it too obvious.
And it definitely worked as Shirou realized the slight way her firm breasts hanged just a little bit from her leaning herself forward a bit. He was interested in knowing her better if it meant what he thought it meant. “Well, that would be an honour.”
She now smiled more strongly, her eyes looking a bit brighter. “Excellent, I would like you to visit us at our castle tomorrow, I shall send someone to pick you up tomorrow after class.”
Shirou totally couldn’t believe it, but he was sure maybe it would be fun. Besides, that would be far from the first time some pretty girl would be inviting him over to have a visit at her place, even the likes of Akeno and Rias had done so. If anything, he was hoping maybe things won’t be as intense as any of those visits he had done with the chesty girls, Serafall was more of a wanna-be than anything, and he truly would be glad if nothing out of the ordinary was to happen just for once…
------
The very next day, once classes had been done for, Shirou had been waiting for the transport that would be taking him to the girl’s place, and much to his surprise, what he saw waiting for him was a top-tier car, the sort that only those with obscene loads of money could afford. Of course, it was a given the girl would do plenty of things to surprise him, but showing off some riches in such a blatant manner truly got him surprised. It really reminded him of all the times Luvia had done similar stunts, either inviting him for lunch at very, very expensive restaurants and the sort, or even having him come along to the mall to buy truly outrageously costly clothing for herself.
Of course, Luvia was also way, WAY MORE FUCKING OBSCENE in her mood, no matter how much she boasted about belonging to the highest levels of the European and Mage elites. She always was shoving her stupid, big tiddies all over his face whenever she had the chance, even going as far as fighting against Tohsaka to see how could be the biggest, meanest whore that could capture his attention. Now, in Kuoh Town, the closest he could see was Akeno and Rias, the two chesty bitches wanting to just have himself for their own lewd fun.
As Shirou had made his way into the vehicle, it started on its path towards the one place Serafall had invited him, and the young Hero of Justice was wondering why the magical girl herself hadn’t showed up just yet. Then again, maybe she wanted to surprise him? That’s one thing he had learned with the local girls, they were all willing to do anything to get his attention, and at that moment he couldn’t help but wonder what sort of perverse scheme was in store for him. A nice car was something that could make any runt excited, and of course, the fact Serafall had acted a bit teasing when she invited him only made him think of what things the girl wanted to do with him. Maybe he was judging her already, but a side of his was telling him to be prepared for anything,
If she wanted to seduce him, well… he would probably pass on it. Too many bitches going after him was something that would become boring eventually, no matter how damn hot a slut was!
As the luxurious locomotive moved through the outskirts of town, Shirou could see through the small gaps between trees, a large, luxurious castle straight out of the middle ages. One that just reminded him of Illya’s place back in his own world. As they passed through the gates, the car was parked directly in front of the stairway of the entrance.
“Welcome, Shirou, now I hope you’re ready for an unforgettable evening as our guest!” Serafall exclaimed with pride, standing right in front of the large entrance gate, her hands laid on her hips in a posture that exuded smug confidence.
“Ah, well, thanks for inviting me, Miss Serafall…” Shirou said as he got out of the car, having the door opened to him by Serafall’s own servant, walking up the stairs. He did feel a bit embarrassed he had to admit, he had gone into the Einzberns’ Castle with those unremarkable clothes of his, but that was due to necessity, here he was coming in as a proper guest and he felt so out of place in such a fancy environment.
“Well, come inside, I shall show you around.” She said, offering a hand, which the redhead took after a small pause.
As they entered, he saw the entrance room, and just like how he imagined, it was exactly like the entrance of a massive castle that you see in television and games and all of the likes. With a huge stairway leading upstairs at the center, multiple hallways, and even the chandelier on the roof!
“Now, this castle was constructed multiple centuries ago…” Serafall began babbling off about some long and complicated family history, all while continuing to walk and hold Shirou’s hand, guiding him through all of the hallways, the rooms, from libraries to all other sorts of areas. Her long-winded explanations were something that Shirou just nodded to, pretending he understood any of it, despite it all being utterly foreign to him.
As they had just let a room filled with a bunch of paintings hang up on the walls, Serafall looked onto the wall outside on the hallway, noticing a wallbound clock. “Ah, it’s dinner time already! Come with me, I’ll show you the way to the dining hall!”
Now she led him to a room on the ground floor, once again, something exactly out of any castle Shirou could imagine. A long table adorned in white cloth, with there even being a candelabra right on the center of it.
Serafall, in a way that made her look giddy with excitement, almost childishly so even, sat herself down on the chair right at one of the two ends of the table, and began tapping one of the chairs next to it, right by the edge, looking at Shirou with a smile as she did so, inviting him in.
Shirou did as she wanted in taking the seat, so far, this visit was fairly standard, he could only hope the food at the dinner was good. He just wondered if, given the interest Serafall showed earlier, if this is when she’d try to make “her move”.
“So! Emiya, I know you are not from here…” The girl said, and the young man was interested by the comment; of course, he had always made it clear he wasn’t from Kuoh Town, but he also hadn’t said enough about his life back in Fuyuki. Just acting like a cute boi (Or rather, the young seventeen year-old who had the body of a cute boi) who moved into a new city was enough for him to keep the act going, but he also was wondering if any of the girls would become too curious. Whenever Akeno or Rias dared to ask more than they should, he just fucked them good and made sure the bitches would forget about ever asking such a thing, but…
He was wondering if he could even try such a stunt with Serafall. Of course, he was going to try something if she had some silly ideas, but at the same time he knew that the girl maybe was too cute for him to let that wild side of his to come out. “Uuuuh, yeah, not from around here, yup. Seems we could uhhh, go out for my hometown when there’s a chance.” The young man said, trying to have a casual talk, but at the same time even making such a proposal totally made the girl more curious.
“OOoooh! Sounds perfect! I dunno where you’re from, though… what’s the name of the city?” The girl asked, and now Shirou was truly feeling cornered. However, just before things could get intense, the sounds of trays making their way into the room could be heard, and the girl’s attention was now focused on the meals coming along. Shirou himself took a look at the incoming dishes, and the smell was truly delicious. He wanted to have a nice meal as well, and it was fortunate enough the girl got distracted enough. Gosh, if he was to even explain how insane the girls were back home… he was now amused by the thought of Artoria totally grabbing every single meal for herself and having a feast. For a girl of her status, the King of Knights really could be funny most of the time.
“Now! Enjoy, Emiya! We got Italian dishes, even some Russian desserts and pastries!” The girl boasted, and the young boi just knew he was about to have something fulfilling. As the dinner went on, he noticed how the cutie was having her own meals with some… odd manners. For one, whenever she had any noodles, she sucked on them with pure gusto, even having eyes that could let anyone know she had purely obscene thoughts in mind, even blushing when she was done with that blatant sucking. Or whenever she took a bite out of a cake, she allowed the frosting to fall all over her chest, especially right between her knockers!
He could tell what she was trying to do, but there was also something that just backfired with it. Despite this fancy castle, this fancy dining hall and this fancy dinner, there was a weird childishness to Serafall that was hard to not notice. From the way she slurped her noodles, to the way the frosting fell on her chest, there was definitely an attempt to appear erotic, but it just made her look… clumsy, almost like a messy eater.
“So. Emiya, I’ve heard you know some powerful magic…” She then said, trying to move on to the big topic she had in her mind since this visit started.
“Uhm, yes, I can uh, materialize blades.” The redheaded runt responded, he could tell already that this is where the incoming attempts at seduction would come.
“That is such an amazing thing, yes…” She leaned closer, a glass of juice in hand, which she leaned down, causing it to drip down right onto her chest! And right down onto the floor, which Shirou also noticed.
“I’m flattered you say that.” Was the only reply he gave, he wasn’t looking away shyly, or avoiding seeing her in the eye, no, he kept constant eye contact with her even as she leaned closer. Which did go quite a bit against Serafall’s expectations, but that was all fine, she could still pull on some moves.
“Well, I would just love to have a big, strong, cool warrior like you among the ranks of our family…” She was now getting off her chair, and Shirou felt that big chest of hers rubbing against the side of his head, he’d normally enjoy this, but the juice she spilled earlier also meant that with it also came a chill wet touch on his skin that ruined the mood quite a bit for him.
“Tell me Emiya Shirou, wouldn’t you like to join us at our mansion, live with us as one of our family servants. I promise you I’ll make it worth it, tee-hee~✰“
“Well, you’re really nice, and I’m glad to have helped your sister before but, I’m sorry but I’m really not interested.” He replied.
“Aw~!” That answer took Serafall off-guard, she had planned this all out! This was when he was supposed to be ensnared under her charms! Perhaps he needed some more further convincing? That was when an idea came up inside her mind!
“Well, in that case, that’s okay too!...” She added, figuring out the words she wanted to say as she went along. “Then at least, even if you’re not my servant, join me in my chambers just once, I still need to… repay you for saving Sona…”
Yes. This was the right move then, if he wasn’t fully seduced now, after a long, passionate night of sweet love-making, he’d be utterly charmed by her and would then agree to become her new servant. Serafall was sure that as a pure-blooded demon she’d be able to rock the redhead’s world far better than those classmates of his ever could!
Once dinner had been done with, Shirou went ahead and began to follow Serafall right to her chambers, and if anything he was really wondering what sort of thing the girl was planning. Of course, she was totally looking like she had some intense idea in mind, and maybe, juuuuuuuuuuuuust maybe if he went along with anything she said, maybe she would stop pestering him about it. Now, he would never deny a girl the chance to have some fun, and mostly, he wanted to see if his skills would be more than enough to keep the inner skank of the girl calm the fuck down. he was more than willing to do even the wildest stuff possible to ensure she would not think about any silly ideas.
As the girl led him to her chambers, he was impressed by the sheer regal nature of the room. It truly looked like it would belong to someone of royal blood, quite close to what either Illya or Luvia had shown to him before, but at the moment he was truly tempted to see what sort of move the girl would try on him. Would she steal a kiss from him? Would she put those nice tiddies of hers against his cock? Gosh, she was truly hard to read, Akeno and even Xenovia were easier to read! They were too damn obvious in how much they desired him for their deepest of slutty urges, and right there he was feeling too tempted to maybe do some teasing if the girl went in a path that bothered him to no end.
“Sooooo! Emiya…” The girl spoke, as she took a seat on the nearest couch in the room, and she had a cute, if playful smile all over her face. “C’mon now! I want to see how good you’re at giving bitches the best fucking ever! Please~?” The magical girl was totally begging him to do something that would blow her mind away. Now, Shirou was totally down to have some fucking with a nice hussy, but at the same time he wanted to see how to best give the girl the sort of intense fun she was looking forward to. Of course, she had some nice fucking tiddies, but they could not compare at all to the obscene size of what either Akeno or Rias got going for, those chest the bitches had totally belonged to the best JAV movies ever, enough to make him blast some strong ropes of cum all over them at the slightest of teasing!
“S-Sure, I uh…” However, he was totally wondering if the girl wasn’t having some nasty trick. What if, once he went ahead and began the fun, she used some bit of magic to truly get him to join the ranks of her family? He knew it would be too bothersome to have some fucking and then find himself under the control of some damn broad…
He thought about it further, yes, there was definitely something suspicious here. But he also felt the same about the other girls like Rias and Akeno, and both of those girls were now sending him a dozen lewd pics and messages about how horny and desperate for fucking they were every single day. If he could get those girls down so bad they’d been essentially domesticated as good little bitches, why couldn’t he do the same for Serafall? Furthermore, for as shady as she was, she also had that childish streak and attitude, that just made her seem less threatening.
It all came down to how she’d react to something, if she reacted the right way, it would be his sign to go ahead and take this bait she was letting on. He tried putting on his most innocent act possible. “Well, I just hope this doesn’t gross you out…”
Serafall looked with anticipation, before suddenly, she felt it, smacking against her head. Despite there being considerable distance between her and the redhead runt. She took another second, turning her head to see, out of nowhere, as if springing from between his legs, a giant pillar of a cock! So tall and so thick, it was like a giant obscene stick, completely out of place with his small frame! In its erect state, even reaching so high up that it reached a height above his own head!
Shirou smiled. His arrival to this alternate world may have aged him down to a small little brat. But his dick, when erect, somehow maintained its virility, he remembered how the other girls too all had the exact same look, a mix of shock at how they’d never expect him to have a penis this massive, of fear at how horrifying it would be to even consider having something that big inside them during sexual acts, and of curiosity, deeply aroused curiosity that wondered how it would feel. It was how it went in Fuyuki, how it went here in Kuoh, and then it happened yet again.
“That’s… so big… How can you be this big?...” She looked at that dong with wide eyes, touching it with both hands, bringing her own face close to it, sniffing it even, taking in that thick heavy musk.
“I don’t really know honestly…” He took a step forward, with that, Serafall leaned back again, her eyes still glued to the giant fuck-stick between his legs, moving a bit “out of the way” to see it from the side in its entirety.
As he then stood right by the large, regal couch, he said. “Serafall, lie down, by your side please.”
“Uh?” She was so fixated on the dick, what had he even said?
“I said lie down, by your side, please.” He was patient in his words, the cock shock was never quick to wear off, he couldn’t blame any woman for not snapping out of that trance.
“Oh, uh, yes!” Her heart was thumping, as she laid down sideways, her large breasts hanging down onto the soft cushion, she already even had an idea of what they were gonna do, as she raised her left leg as high as she could. She gulped, this was so insane, was that thing even gonna fit inside? Would it hurt? Or would it feel amazing? At that point the reason she wanted to do this with him wasn’t even in her mind anymore.
Shirou totally was ready to show the cutie some intense fun, she was totally going to regret having invited him over, and he wanted to see how shameless she would get for himself and his fat piece of cock! Oh yes, this was almost like that one time he plapped Akeno at the pool, the dumb broad had not been ready to see his fat cock so, SOOOOOOOOOO FUCKING HARD AND READY FOR SOME BREEDING! “Now, we’re gonna have some fun, Serafall. I hope you enjoy this, we’re gonna be here all day…” The red-haired boi said with such a growl, and the girl was truly feeling as if she had never, never interacted with anything obscene before!
Sure, she would never admit to being a crass bitch, but she had seen her fair share of JAV movies and the sort, and yet, experiencing some FUCKING FAT BOI-COCK at home was truly something else! She was at the very least glad her sister wasn’t around, she had absolutely no idea how she would be reacting at the obscene scene happening. “Y-Y-Y-Yes! Yes, Emiya! Just… go for it!” And just as she was done speaking, the big-dicked brute went ahead and slowly pressed that fat piece of cock against her cunt, and a grunt escaped from the lips of the runt as the pressure he was feeling was too much. It was a given that the magical bitch hadn’t truly fucked an actual cock before, the same tightness is what he felt when he wrecked Luvia~.
“OUUUUUUUUUGHHHHHHHHHHHHHHHHH! EMIYAAAAAAAAAAAAAAAAAAAAAA! AWWWWWWWWWWWWWW FUUUUUUUUUUUUUUUUCK YOUR CAWWWWWWWWW!! YOUR CAWWWWWWWWWWWWK IS SO FUCKING FAAAAAAAAAAAAAAAAAAAAAAT~!!” The dark-haired slut moaned out as she just felt how that fat dong was spreading her pussy wide in ways not even her best of dildos had done before. She was feeling the pure, raw force of that dick wrecking her cunt, and she just loved it! She fucking looooooooooooooved it, and she could tell the boi was saving his best of energies for last! She glanced at the runt, and she was delighted to see how blissed-out he was looking, how his eyes were looking ferocious as he was ensuring every single thick inch of his cock got sucked inside her cunt.
“F-F-Fuck…” Shirou himself held on to one of the meaty legs of the bitch, and he grunted as the sheer tightness of that cunt truly made him want more! Yes, this girl truly was going to become a good cumdump, she deserved it for totally messing around with him~.
He could feel a burn on his legs, which shook him off for a bit, as he adjusted his posture just a bit, aligning himself properly a bit more, and thrusting his hips all the more, inch after inch of the huge cock piercing through the hole of the girl. Until finally, he was balls deep inside, and so close to that fat thigh of her raised leg he was hugging it tightly.
His hips shaked a bit, before he focused, and started bringing them back, before driving them forward once more. Something that made Serafall clench her teeth for a moment, a shock tingling through her spine from the sensation. Shirou did it another time, and this time, the thrust forward made the girl’s whole body shake from the momentum, like ripples on water, and the slap-like sound of their flesh softly colliding reverberated inside the room. And he did it a third time, this time, with as much force as possible, and this time, she let it all out. “OoooooOOOOOOOOOOOOOOWWWWWWWWWWwwwwwwwWWWWWW!!!!”
Her deepest moan yet, spurred from the indescribable feeling of having her pussy stretched out and reshaped by a colossal cock. Something so strong it was making her even feel light-headed…
Shirou took this as the go-sign he wanted, and then began moving his hips again. But not with any pause, no, his body entered a rhythm, a rhythm of constant thrusts back and forth, repeatedly inserting and feeling his dick rub through the insides of the hot wet cunt of the girl over and over. The way those pussy flaps wrapped around the entrance, of the hot fluid inside that made him feel like his cock was boiling, and the catharsis of hearing her moans, it was incredible.
And as he continued on, his rhythm grew faster and faster, his thrusts going in and out at rates the poor girl couldn’t even keep up. All of what had happened with the previous thrusts, the moans, the way the momentum rippled through Serafall’s body, and the slapping sound echoing, it all began repeating at faster and faster rates.
“Come on Serafall, there’s no need to… hold back!...” He growled, while he was in control of the situation, the pleasure flowing through his being was still like a strain that made concentrating hard enough to talk still a bit difficult. “If you have to let it all out, then do it!...”
“Yes! I! I’m cummiiiiiiiiiIIIIIIIIIIIIIINNNNNGGG!!!!!” The pure-blooded demon cried out in a deep moan, a spine-wrecking surge of pleasure jolting inside as she could feel on the insides of her cunt a cathartic feeling of release. Her cunt squirting out wave after wave of pussy fluid that Shirou could feel too, coating his dick in it.
Her heart beat the hardest it ever had before as she began to moan out from the feeling. Her whole body felt like it was on the verge of melting away…
For Shirou, it was only about a little more than half a minute, but for the girl, it was like hours had passed during the short orgasm.
Shirou was glancing at the way the cutie was looking, and he decided maybe his dick had gotten enough fun out of the slut. Slowly pushing his dick away, he grunted at it was clear enough the slut still wanted more out of him, but the runt was not one that would ever deny a girl the chance for more breeding, no matter how obscene said girl was. His eyes were focused on the bitch, how she was truly panting for air, and how she looked as if she had received the best fucking ever. That was a given, as his cock was always capable of turning any girl around into such a mess, even clear sluts such as Rias or even Tohsaka were always behind his cock and wanting to get to experience that dick for the first time, which only made it all too amusing for himself.
“Well, you’re looking too pleased… I suppose it would be way, way better if you’re the one serving me.” The boi said, and the girl’s wrecked mind was barely even registering any of the nasty words the red-haired brute was saying. “I dunno about serving you, seems I’d be too busy fucking you, so how about you instead providing my dick the fun it deserves~?” The runt added, and that only ensured the girl’s plans would be foiled before they could even begin. The young man was wondering what response Serafall would give, there was no way she would drop a perfect plan!
Serafall was, however, too turned-on to let any rational thought be processed by her perverse mind. Of course, she wanted that perfect cock to be buried deep inside her slutty body every single moment of the day, there was no way, no way at all she would not have that cock for herself, and while her family would complain she had taken the path of some nasty whore, there was no other path to take from there. “S-Sure! I… I… I WANNA SERVE YOUR CAWWWWWWWWWWWWWWWWWK! JUST FUUUUUUUUUUUUUUUUUUCK ME MOOOOOOOOOOOOOOOREEEEEEEE! PLEASE GIMME MORE OF YOUR PERFECT CAWWWWWWWK!!” At that moment, any sense of pride the girl had for her own family, for her own honor was gone, as the only thing she desired was to become the best cumdump for the hot-blooded runt. Indeed, she was more than willing to throw away everything that made her such a top-class girl, as long as she got fucked, that is all she cared for~.
Now that the Hero of Justice was hearing how obscene the dark-haired bitch was, how she had become too addicted to his cock, he went ahead and took hold of her, using all of his inner strength to just turn her to the side as he got her up, and now she was about to take more of that fucking fat dong deep inside her cunt once more. “GET FUCKING READY THEN, NOW I’LL FUCKING BREEEEEEEEEEEEEEEED YOU! GONNA FUCKING WRECK YOUR CUNT REALLY, REAAAAAAALLY GOOOOOOOOOOOOOOOOOOOOOOD~!! GONNA FUCKING FLOOOOOOOOOD YOUR CUNT WITH ALL MY CUMMMMMMMMM!!” Shirou roared out, soon sliding that thick cawk inside that bitch-tier cunt!
Despite his size, another physical element of Shirou that had remained despite him being aged down besides the size of his cock was his physical strength and athleticism, allowing him to still hold Serafall herself in his arms from below by the thighs. He spread her legs, and began pistoning his dick inside!
Both began moaning out, Serafall experiencing once more the way Shirou’s cock and its sheer girth would stretch out the inner walls of her cunt as if it was made of elastic, and Shirou feeling once more that perfect sensation of a hot wet cunt so tightly squeezing down around his member. And now, it feels even better! The way her pussy fluids that had gotten his dick all wet, were making this feel so much more sensitive, so much more slippery, so much faster.
His legs began shaking a bit, as he for a moment felt as if he was gonna lose his balance, but he focused hard on his footing, and tightened his grip on the girl’s legs. Clenching his teeth, as he proceeded to pump his dick on her pussy as hard as he could. Feeling that white-hot stimuli surge within his loins.
“Are you ready for my load Serafall? Ready for me to flood your womb like I have so many others?...” He smugly commented. Shirou always acted as a polite, good-natured boi, which made these moments, these times in bed where he got to truly be so bold and aggressive, feel all the sweeter.
“Yes! Yes!... Fill me with all of your cum! Knock me up with a dozen runtssss!!!” The demonic girl replied, so intoxicated with lust at this point she was essentially delirious. Shirou smirked at her reply, as he stopped his strong movements and instead, lodged his dick as deep inside her pussy as he could, and stayed still.
He groaned a bit before moaning out. “Then… take… it… ALLLLLLLLLLLLLLLLLLLLLLLLLL!!!!”
And with it, came a burst of hyper-thick semen that began gushing out of Shirou’s cock like an erupting volcano, all being let out directly inside the cunt and womb of Serafall. The redheaded runt could feel his own mind become consumed by ecstasy, his brain feeling almost fried from the pleasure of the sense of release, the cathartic feeling of just load after load after load of jizz being let out.
“UooOOOOOOOOOOOOOOHHHHH!!!” Serafall too began moaning out as she had her own powerful orgasm, her second already that night. Feeling the hot white fluid covering the inner walls of her cunt, and the feeling of her own fluids slooshing through, the two mixing together in a sticky, slimy combination, something so unlike anything she had ever felt before.
By the time Shirou was finally done, a big cum gut had formed on the demonic girl’s stomach, as Shirou let her down on the couch again, and she immediately rolled over to lay on her back, panting for air, drained of any energy. But the boi would then get on the couch himself, and line up his dick directly with her big, open mouth!
The two kept fucking until four in the morning, a record that truly impressed the Hero of Justice…
------
Shirou truly felt like he’d outdone himself. No matter how many times he’d fucked around with Rias and Akeno, the obscene breeding he got done with the magical girl truly went beyond his wildest of dreams, not as if he minded it, of course. He was truly hoping the nasty debauchery that he got done with the girl would have been enough to satisfy her deepest of desires, and indeed, the intense cumloads that had leaked away from his shaft should have been more than enough. He had pumped out similar amounts of sperm deep inside any slut that decided to play around with his cock, even Artoria and Tohsaka back home had been enough to make him feel like truly the most shameless brute out there.
Just as he slowly opened his eyes, he noticed he was still in Serafall’s room, and that only made him feel a bit too puzzled. He was expecting to at the very least been given the chance to get back to his own residency after giving the girl the fucking of a life-time. Maybe no servant of hers wanted to do such a duty? But just as he had begun to wonder about how to best get out of the castle however, he began to feel something funny right in his lower-body, and he noticed how he was almost covered in bed-sheets. But within the sheets, he noticed some movement, and he just could feel something softer against him. “Huh? What the…?” The young brute muttered, and reaching over, he took hold of the covers, and as soon as he pushed them away, he was greeted to the sight of…
Serafall FUCKING RUBBING THOSE FAT AS FUCK TIDDIES OF HERS ALL OVER HIS COCK! Gosh, there was truly nothing stopping the girl, if at all? Of course, there was the fact that he had made it very clear she was to serve his cock, and maybe she had accepted the challenge without putting any sense of logic into his command?
“Good morning, Master Emiya!” The girl greeted Shirou, which only did enough to bring some memories of his own routine back in Fuyuki, especially at how Tohsaka and Saber often would awaken him with some nice cock-sucking and kissing. “Seems your cock was SOOOOOOOOOOOOOO HARD EARLY in the morning, so hopefully this can make you cum soon!” The girl spoke, and she increased the speed of her tiddy-fucking, totally intending on getting the young runt to cum and ensure he would be blasting her dumb face with some heavy loads of sperm. Shirou groaned, especially as the bitch was so, so very aggressive in her move!
Shirou slid his hands beneath his head, relaxing himself and letting the demonic girl do her service. Enjoying the way those fat tits of hers just squeezed down on his cock as well as how that tongue rubbed all over his precum-leaking tip. It wasn’t as good as a titfuck from those inhumanly busty girls like Akeno, but he was sure that with enough practice and enough times, her breasts would grow in both size and skill to match. It was how it went in his old world after all, even Saber and Tohsaka had relatively modest chests at first before the fucking became a regularity in their house.
“Your cock is so fantastic Master!” Serafall exclaimed with pure adoration before rubbing her lips over the tip for a moment. “Every single woman in this world should bow down to it! It’s what it deserves!”
“Yeah, yeah…” Shirou couldn’t help but roll his eyes a bit at her words. He had his urges, but he wasn’t the kind to go out there and try to get as many sluts as possible, he’d much rather let it come naturally like this. Though this did always lead to his bitches always being the weirdest girls.
However, there was no time to ponder about those things, as he felt a fire lit inside him from one moment to another. Something sparking from the way those big tits rubbed against his cock, how the slit of his dick felt with the mouth and lips of Serafall. And it made him let out a quick moan that the demonic girl was quick to notice.
“Ah! Master, are you about to—-!!!???” Before she could finish, he grabbed her head, and shoved it deep down onto his dick, forcing it to take in as much of his length as he physically could.
The sheer, raw move had truly gotten to wreck the girl’s mouth as well, as a cock-shaped bulge soon could be seen all over it, and the sight alone was more than enough to make the red-haired brute FUCKING FUCKING PLAP HER MOUTH-PUSSY SOOOOOOOOOOOOOO FUCKING MUCH, SHOWING THE BITCH NO MERCY AT ALL AS HE WANTED TO ENSURE ANOTHER HOLE OF HERS WOULD BE RUINED!!
And then, his cock exploded with cum inside her throat, splattering down on the girl’s throat and completely clogging her esophagus with his jizz. Her eyes were rolling from the overwhelming feeling, as the cum began overflowing and even began to leak out from both her mouth and her nostrils.
Shirou felt that feeling of release pound at his being over and over with each load and string of that syrupy cum that his cock let out. Until, finally, after what must have been nearly a full minute of ejaculating, he was done.
“Ahh… ahh… that was fantastic, thanks…” He said, breathing slowly and heavily, enjoying how much of a cum-covered mess Serafall’s face was now. After letting his cock out of her mouth, she only responded with a big, drunk-looking smile. And best of all? Her belly had been bloated to absurd levels thanks to the insane loads of sperm that had been blasted deep inside her mouth! The size could be said to be… what, 30, 50 beach-balls combined? But of course, Shirou knew he could do way better than that…
“*KNOCK KNOCK*”
Suddenly, a voice from outside.
“Mistress Leviathan. Your sister has arrived home. She’d like to see you.”
Shirou’s eyebrows were raised in curiosity, and Serafall just looked at him, not responding to the servant outside the room, only anticipating what Shirou would say.
“Well.” He raised himself from the bed, a smile on his face. “I guess me and your sister need a proper introduction now don’t you think~?”
THE END
