[Beer Belly, Navel Fucking, Futanari]
"I still can't believe you did this to me. What gave you the bright idea to ruin my figure like this?!"
"Well, I could give a lot of different excuses if you'd like, Jalter. Buuuuut... I just really wanted to see what you'd be like with a big firm belly. Is that so bad?"
"Damn right it's bad! I don't wanna look like a fatty, Master! Change me back already!"
"Nah. You're too cute when you're angry like this."
After dealing with the different Singularities and everything that tried to threaten Human History, Chaldea's Master decided that it would be best to just relax and enjoy life. Which was why she currently found herself sitting in a cozy little café with one of her Servants, both of them having taken an excursion to one of the fixed Singularities so they wouldn't have to worry about anything.
The Servant that she had brought with her had once been an enemy. Jeanne D'Arc Alter. Or Jalter as her Master affectionately dubbed her. Although she was merely a fabrication brought into existence by the power of a Holy Grail, she had managed to come into her own through her personality developing. Growing angrier at the world and the circumstances that led to her existence, as well as growing very weak to teasing from those that thought that her anger was little more than temper tantrums.
It also didn't help that her Master had grown so close to her that she decided to mess with her more. Jalter's figure had seen much better days, with her stomach struggling to keep pinned underneath her zipped-up dress. Not only that, but there was a significant amount of meat on her body compared to when she was ruthlessly pursuing her rage against the world. All because of her Master.
"I'm not cute, Master!" Jalter cried out as she grabbed ahold of her glass full of alcohol. Such a meager glass that she had ordered to try and look like she was being modest. And yet now she was downing the contents in one big gulp, every time that her Master forced her past a certain threshold. "You're the cute one, got it!? I'm not cute, you're cute!"
"It takes a cute girl to know a cute girl." Gudako giggled as she slowly sipped from her own glass. "Besides. What's so bad about being cute? It means that I'll take good care of you. Always keeping you near and making sure your needs are handled. Don't you want that, so your tummy'll stop rumbling?"
"It keeps rumbling because you keep playing with it and making it WOOOOOORS-"
As Jalter started to complain about her current state, she felt a little heel carefully press against her precariously contained belly, and she couldn't stop herself from letting out a rather shameful belch. Her entire body rocking as all that pent up gas poured out from her lips, while her cheeks grew nice and red. This wasn't the first time she had belched while she was stuck with this girth, and it wouldn't be the last. Not while Gudako was her Master...
"S-Stop teasing me like this, Master!" Jalter cried out as she tried to cover up her mouth as another burp slipped free right before her hands made it all the way across her lips. It was frustrating to sound like this. Frustrating beyond belief!
Gudako just giggled as her sweet Servant tried to look like she had a choice in the matter. As long as she continued to be so cute, there was no way that she would tone down the teasing. She wanted her to be as cute as possible. And that meant she would keep teasing her. Again and again and again. No matter what happened...
Jalter watched her Master's expression grow from blissful to downright erotic, all while she heard the sound of something hard hitting the table. Which in turn made her blush even harder. Of course she had to get hard when she saw her like this. "C-Can't you just sit here and drink with me instead of..."
"I've been drinking all this time, Jalter." Gudako smiled as she poured herself another glass, carefully sipping the alcohol as she kept her eyes on the white-haired Servant. "And every sip just makes you look more and more beautiful. Do we have to wait until tonight?"
"We do. I'm not letting you ravish me this early..." Jalter muttered, even as she pinched her thighs together. "Just... Just focus on drinking. And stop teasing my belly, it's getting really annoying!" She cried out, trying to force her Master to ease up. Just this once.
Not that she got what she wanted. In fact, the belch that left her lips just seconds later was directly caused by Gudako's foot slowly pushing into her gut yet again. Leaving her trembling yet again, and beyond embarrassed at all those crude noises that left her lips.
She'd pay her back once night rolled around. For sure...

Even though they didn't belong to this Singularity, that didn't stop Gudako and Jalter from having a little place to stay. A simple apartment that was nice and soundproofed, because they had previously been scolded for being too loud at night.
Now why would they be so loud? Well, it just happened that the Servant was a bit of a screamer. She couldn't handle the pleasure that came with servicing her Master, and kept on screaming in delight whenever they made love. Which was every single night they spent together in this apartment.
Even now, Jalter was only barely ready for what had come to be a regular part of their love life. Her naked body resting on their shared bed, her firm belly sticking into the air. She cursed the fact that it couldn't just sag down and relax against her. No, it was so firm because of her Master's specific wishes.
"I never get tired of seeing this." Gudako giggled as she carefully rubbed her hands up against that bulging beer belly that had grown from Jalter's stomach. She didn't want a simple sagging piece of fat that she could ram her rod into. No, she wanted something tight and nice. Something that she could rut for hours without growing soft. And this was her solution...
Jalter looked away as much as possible. Even though she could smell her Master's arousal. Even though she knew what she was going to do when she got the chance. She hated it. She hated it above everything else. Why did she have to be like this? Couldn't she just be normal and... N-No, she had to avoid thinking about the passion that would come from that kind of love. If she thought about how much her Master could shower her in love, then it would actually come true. And then...
The white-haired Servant let out a shriek as she suddenly felt a pair of lips push against her cheek. Courtesy of her Master, who just giggled in response to her exaggerated reaction. She really did love seeing her react like this. Whenever she got too caught up in her own thoughts, whether they revolved around her feelings or her hatred towards the world that made her... She was so easily kissed and overpowered in one swift motion...
"S-Stop that." Jalter muttered. She couldn't even manage to scream. Not when she was like this. Not while her lower lips were drooling. Not when she was turned on beyond belief thanks to her Master's presence...
Gudako just giggled in response as she lifted herself off the bed, showing off her thick shaft in the process. The manhood that she always tried to keep hidden underneath her clothes. But now that she was in private with her dearest Jalter, she could do anything. She could jam it into any hole she could think of. And she had already gone through the trouble of making the best hole in the whole world, so what else was she going to do?
As she pressed her rod up against the tender navel that was practically begging to be fucked, she motioned for Jalter to reach up and weave her fingers in between her own. Just so they could support one another. And despite how much she would've normally tried to struggle and try to avoid it...
Jalter grabbed ahold of her Master's hands, and let their fingers weave together as their grip tightened. All while she trembled in anticipation. It's not like she wanted to actually enjoy having her belly fucked. It was the worst experience. But underneath all of her deflections, she really just didn't want to disappoint her Master. She had done so much for her, even if she had teased her...
All of those thoughts, all of those complex excuses that she made up to try and avoid admitting her true feelings, quickly broke apart as she felt her Master's cock slam straight into her tight belly pussy. It was so intense. She knew that it was going to be intense and she knew exactly how it would feel to have it slam into her. And yet she wasn't prepared in the slightest! She wasn't even close to prepared to feel the cock pierce through!
"Mmmmph! Tight as always!" Gudako cried out in glee as her hips took over most of the work. She didn't need to concentrate on fucking, because her body would instinctually thrust forward. All while she giggled and looked down upon her white-haired lover. "Don't you love this, Jalter? Having your beer belly fucked again and again?"
Jalter wanted to try and respond. But the sheer pleasure of it all, the sheer pleasure of having that shaft jammed into her hole... The sheer pleasure of having the contents jiggled around... It was too much. It was far, far too much. How was she supposed to handle it? There was no way that she was able to handle it. No way!
Moan after moan echoed out, turning into proper screams as her Master thrust harder and harder into her soft and squishy belly pussy. She should've gotten used to it after she had done it so many times. And yet here she was. Screaming like her life was flashing beyond her eyes.
It felt far too good. It always felt far too good. She could feel her soul trying to leave her body... Or at least, that's what it felt like. She was never really able to articulate what it was like being fucked so intimately, it just felt so intense that she always felt like she was about to pass out at any single moment.
As for her Master? The sight of her dear Jalter's expression shifting rapidly between bliss and fear and exhaustion and every single possible emotion that might be bubbling inside her... It was such an entertaining experience. It made her thrust harder and harder, just to see how quickly her feelings might shift. How quickly she might overwhelm her all over again.
But she couldn't just keep thrusting all the time. That hole was so overwhelmingly tight that she was climbing closer and closer to a climax with every passing moment. And just as Jalter's expression started to show pure bliss..!
Gudako thrust as far in as she could possibly go, her fat balls slapping against that firm belly as the 'lips' of her belly button kissed the base of her rod. All while she squirted out as much of the cum inside those balls right into the hole, quickly causing it all to spill back out as it struggled to contain any of it.
Jalter's climax was just as intense, the Servant's eyes rolling into the back of her head as she struggled to keep conscious. It was too much. Too much, too much, too much! Why did it have to be so intense?! Why did having her belly pussy fucked have to make her squirt out a small puddle's worth of feminine cum, staining the bed below in the exact same spot as every other night!?
Eventually, their climaxes came to an end... And Gudako slowly pulled her cock out of the proverbial stone that it was stuck inside, cum still flowing from that very same hole as the pressure within was now equalized, before laying right down besides her dear Jalter.
"I love you, Jalter." Gudako said, planting a kiss right on the cheek of that adorable Servant that had been there for her for so long... And didn't kill her when she tried to alter her with a command seal.
Jalter huffed and turned her head away from the wicked girl that had caused her to fall so far... Before quietly and slowly turning her head to face her and planting a kiss on her Master's cheek. All while still leaning into her usual Tsundere behavior as she whispered into her ear...
"S-Stupid Master... I love you too..."
