[Growth, Semi-Twinning]

"Aaahhhh! I can't stand that man! No matter if it's the youngest version, if its the version when he was still on the rise, or the version when he rules Uruk! He always knows exactly how to get under my skin!"

"It's alright, my Goddess. It's alright. I'll make sure that he pays for what he's done. It's not fair that he keeps disrespecting you like this, he really should know better! You're a Goddess, after all!"

"Ah, Master. You know exactly what to say when I need to hear it. Even if it's a bit much. Here, lay your head down on my lap."

This was a small peek at the strange relationship between the Master of Chaldea, Gudao, and the Archer that had helped him during his time in Babylonia, Ishtar. He had managed to summon her not long after those events, and they had quickly grown close. Mostly because the Master was naturally weak to assertive women like her. But it was not a relationship built on love. It was a relationship built on a simp and the woman that he worshipped. Because of course he had been charmed by her natural beauty, of course he would end up falling in love with somebody that was far beyond him.

It certainly didn't help that she paid his devotion back with tender treatment. There were a few women that he had managed to summon that ended up getting his complete and utter devotion before Ishtar, but they never truly paid him back. None gave him more than simple thanks. Ishtar was different in that regard. Letting him rest on her lap and experience heaven on earth, the young man doing his best to not drool all over her thighs as he laid there...

Ishtar huffed as she slowly ran her hand through his hair. This was something that always managed to calm her down, having her Master in a position where she could play with him and do whatever she wanted to him. But she was still upset over being bullied by all three versions of that awful blonde. "Can you believe it, Master? They all called me terrible names, all because I just wanted to sneak out a couple of gems from their treasury!"

Gudao nodded rapidly while on the Goddess' lap. "Absolutely! Everything should be yours, Ishtar! You're a Goddess, after all! They should all just kneel before you and realize their mistakes!" He cried out like the simp that he was. Whenever he got like this, he completely ignored any wrongdoing that the one he loved had done. They were never in the wrong. They were always in the right. Besides, Ishtar should get as many gems as she'd want. She was so much more beautiful than anybody else in the entire world, across the entirety of time itself. She deserved the whole world, so a few gems would naturally be hers as well.

"Exactly! On their knees, heads pinned against the floor, so I can make sure they taste the dirt. Not that I'd ever walk on that dirt, I'd never let these feet get dirty. But they can always lick my soles clean to make sure there's not a speck of dirt on them!" Ishtar laughed, too pleased with the fantasy of dominating that awful man thanks to all the worship that was being piled onto her shoulders. So much that she almost felt like she was getting a little stronger. Almost. Maybe if she made a couple of the other Servants see things her way and made them simp just like Gudao, then she might actually have the chance to turn the tables on Gilgamesn for once.

There was nothing in the world that Gudao wanted more than seeing his Goddess at the very tippy top of the ladder of dominance. He wanted her to become a Goddess on par with the ones that had created the world. No, beyond that! He wanted her to rule over every single possible version of reality, every single possibility of the Kaleidoscope. But how could he possibly accomplish that? How could he make his wish come true, if he didn't have a proper grail to wish on, nor the seals to accomp... Hold on.

Where were his Command Seals?

As Gudao got briefly distracted by the lack of seals printed on the back of his hand, Ishtar blinked a bit. What was this sensation growing inside her? It was like her heart was pounding against her chest, but it wasn't actually her heart. It was something else. Something that made her tremble from head to toe. Something that made her feel... So much more than she already was.

With every breath that Ishtar drew, she slowly but surely grew. One tiny little inch per few seconds. Inching closer and closer towards the ceiling, though not so far that she actually ended up bumping up against it. She had only grown about an extra head or two in terms of height, but what she lacked in terms of height she more than made up for in terms of width in all the right spots.

Ishtar was not a girl who was lacking in terms of curves, but she was still on the modest side of things. Not any longer. As this new sensation burst through her and pounded against her inner soul, her cup sizes drastically grew. One cup, two cup, four cups, by the time that she looked down properly at her breasts, she could practically lose anything inside her cleavage at this point. And to her surprise, her top had managed to keep itself together as well, as if this brand new divine figure was something it had always been designed to compress.

Of course it wasn't just Ishtar's breasts that were getting the growth treatment. Her hips, and especially her ass, were also being blown up due to the new power within her. While her pants definitely grew tighter to the point where parts of the fabric were being stretched out until it was practically flossing the cavern between her cheeks, they still managed to keep her modesty in check. Well, as much modesty as one might have when their thighs were big enough to crush a man's head between them, while also having the hips and ass to handle more broods than the Primordial Mother Tiamat ever could...

By the time that her changes came to an end, Ishtar could feel her arousal climbing. This growth, this brand new feeling inside her... It was power. She had much more power than ever before. But how did she gain this power? As far as she knew, the only one that had... been worshipping her...

Ishtar's eyes fell on Gudao, whose face was now partly pinned in between her thighs. And after quickly pulling her thighs apart so he wasn't being crushed between them, she couldn't help but grin. "Oh, Master? What did you do?" She wasn't mad at him. Far from it. She just wanted to make sure that he understood what he had done...

Gudao took a deep breath as he was freed from that squishy prison. While he didn't hate it, he was definitely not prepared for it. In fact, it almost felt like he blacked out when he was stuck in between those thighs. So he turned towards his Goddess, hoping to answer her and try to understand what he had done...

Only for his mouth to forcibly drool as he looked up upon his Goddess. She was a beautiful woman before, but now that every single thing about her was bigger and better, he couldn't contain himself. He wanted her. He needed her. So much so that his pants had already started to tent. He craved her above all else. He didn't understand how or why, but she had managed to become the kind of Goddess that he wished that she could be. When she was like this, there was no way that she'd be bullied by that awful blonde man... N-Nor by anybody else...

Just laying there was practically hazardous to his independence as his eyes grew nice and dim. It was like there was an invisible barrier of pure beauty around her. And being in contact with it projected so many mental images of what she could do to him into his head. How she could reward him for his worship. And what he could do to worship her even more...

"I.. I..." Gudao muttered, barely able to string together a coherent word thanks to the drool pouring out from his lips. He wanted to explain, but he couldn't. There was no way that a mortal like him, somebody as pitiful compared to the Goddess in front of him, could possibly be able to explain how he had been involved in improving her.

Which was why he ended up rolling right off his Goddess' lap, landing softly on the floor below before immediately starting to kiss those beautiful feet of hers. He didn't have the right to look upon her. All that he could do was kiss and lick those feet, to make sure that they were as pristine as possible. That was the only role that he could possibly fill..!

Ishtar laughed a little as she saw how quickly her Master crumbled underneath her brand new radiance. But then again, he had always been such a good simp. As much as he probably though he didn't deserve to be gazed upon by her, he had more than earned this.

"Alright, Master. You want these feet? I'll give them to you. Just because you know where you belong." Ishtar chimed, lifting up one  of her feet, the same one that the Master was currently busy shoving all of his devotion onto, before pressing the sole of said foot right up against his face. In the process, forcing him to sit up. She wanted him to be able to look upon her ever slightly when he worshipped her. Not just devote all of his will to look upon her foot.

Indeed, that's exactly what Gudao did once he was forced onto his knees. While his lips and tongue were busy pouring more and more worship onto that wonderful sole, his eyes were now devoted to beholding the splendor of his Goddess. He could feel his body trembling the longer he looked at her. Ah, he wasn't worth being in her grace. She was so beyond her. But at the same time, she trusted him to care for her sole...

The more that he liked away at her foot, the more he kissed it and the more he looked upon her, the more his body started to shift and adjust. He had been such a devotee, but he needed to look the part. Being a normal boy, much less one as plain as him, was unacceptable. Which was why his clothes started to shrink further and further...

Until he was wearing the exact same outfit as his dear Goddess. The same tight top, the same tight pants. And while his bosom did not push out to fill the top, his butt did start rounding out so it properly fit his brand new pants. He was being ever so slightly nudged towards the perfect sense of beauty, the kind that emulated his Goddess, while remaining male since he had not yet earned femininity like hers. A femboy was all that he could be, at least until he had shown further promise.

For now, as Gudao continued to pant and moan as he licked and kissed that foot, he was little more than a semi-twinned copy of his Goddess. One that had the same kind of curves that she had before her ascension. And as his seals slowly started to regenerate, now barely visible on his rear instead of the back of his hand, that devotion of his could lead to her gaining even more power.

Ishtar laughed as she looked upon the boy that worshipped her. He looked so tasty now. But more importantly, if she could change him, then she could change everyone else in Chaldea too, couldn't she? If that was the case, then there was no possible way that Gilgamesh could bully her ever again...

A devilish scheme started cooking inside the overpowered Goddess' mind. A scheme that would ultimately result in Chaldea becoming little more than a temple devoted to her and her alone.
