Gluttonous Desires

This was what she had been saving herself for, and why it was so important to escape the confines of her bedroom and make it out into the cooling night air. Twilight was confident that now she was…mostly outside the building she could teleport herself to the outside of Sugar Cube Corner, there was no way she was going to get in. Her ass alone could put a serious dent into the building, and she wouldn’t want to upset Pinkie or the Cakes. Of course she would pay for the food later, being Princess did have certain financial benefits.

Twilight needed everything for this, she had teleported countless times before, but this time was very obviously different. The huge belly sloshing away between her hooves and the towering monstrosity behind her made that obvious enough. Her horn light dimmed as she prepared to slacken off and temporarily stop the Aura spell while she teleported – it had done a tremendous job of transforming her to her new colossal size so far and she would need it again when she arrived in town. Her body could now sustain itself and there was no chance she would shrink back to her normal size, that would require another spell.

As the aura subsided she had a brief chance to relax without the stress of having to keep a magic spell constantly on. As she did so her body sagged slightly and her butt cheeks very quickly became the victim of gravity, having held them up to a lovely round shape before using the spell. They suddenly also became very noticeably heavy, and due to Twilights body not quite matching the size of her incredible ass, she actually tilted up slightly forward as the butt took up the weight.
She was already missing the food, and started to begin casting the teleport spell. Usually this took mere seconds, if that – but there was no way she was going anywhere fast with a body and butt the size of a small house. A faint purple glow surrounded her, and then there was that familiar ‘ping’ sound as her whole body was transported magically from her castle, to a little way in town to the square in front of Sugarcube Corner.

There was a light thud as Twilight’s frame came to rest in front of the bakery. Nopony noticed the huge, swaying mass of flesh that had suddenly appeared in front of it. It was now past midnight, all of them tucked up in bed sound asleep. Quickly she re-applied the aura spell and her slightly drooping but cheeks came back to their full fleshy round glory above her head. Once again, and for the final time, she put that extra bit of magic effort in and the panties – almost forgotten until now, they again adorned her rear end. She was surprised they had yet to give way to her ever expanding ass cheeks and pondered what ponies might think when they rose from the beds in the morning, as she had a great plan for a grand finale with the treats from Sugarcube corner. But that was yet to come.

Being completely unable to move, another small amount of magic was expended to ever so gently release the grip of the lock on the front door, and again to open it so the bakery was now open to Twilights waiting, gaping jaw. As she used the last of her reserves she collected up the food that was inside the shop and transported it outside. It was huge…she might even say, a copious amount that was now in front of her widening eyes. Twice as much easily as she had gotten out of the castle pantry. It was perfect as she knew where it was going and exactly what she was going to do with it.

Before she began, Twilight performed one last spell on the now marquee sized panties adorning her beautifully big flank. A strengthening spell to make sure no matter how much her giant rotund cheeks pushed up against them and stretched them out, they would hold fast against the advancing and expanding butt.
This was it, time for the final phase – the big push (Twilight hoping the ‘push’ would be her butt, backwards and further above her body of course). She summoned the first cake towards her gullet and it slipped down her throat incredibly easily. Much more pleasant than the pantry food back in the castle, the creamy frosting on the cake making each bite and chew a pleasure. The other added bonus being the food was much more fattening, and quickly she began to expand herself again as she gulped down more and more of the cakes. She could feel her body convulsing as it adjusted itself to the new sensation of the sweets entering it, and powered through eating more and more with each bite.

Her huge body rose further and further above the ground, and widened to compensate. She was eating like a champion and pushing herself far beyond what she thought capable, the cakes were so moreish that she wanted to cram her mouth as full as possible of what she was eating to add to what she was feeling within herself. She also noticed despite her size she was actually getting cooler in the night air and with what little was left of her body, now a huge mass of fat resting beneath her overly fat face, she wiggled herself to see if she could feel what was making her cooler, and then it dawned on her.

Her ass was now so big, so colossal that it had risen high enough to cast a shadow over her back which was climbing as she ate more and more. The huge rippling cheeks were rising high above her body and she was thankful for the coolness. Again this pushed her further to eat more so the shadow could extend over her. Her cutie mark now bigger than a house, it showed off the sheer size of her massive flank even more, the star pattern that sat on her backside now larger and more graceful than anything else in the entire town.

Twilight had put herself where she was on purpose, there was a small, but oddly tall house just behind her, now no longer used due to its irregular size, nopony seemed to be able to live in it very long. In fact it was scheduled to be demolished soon, and Twilight thought as it was her royal duty to help ponies wherever she could, she was going to help. She was going to crush it in between her huge, swelling cheeks that even now were expanding their way towards the building. Her ultimate plan was the wedge the poor building, doomed to be crushed between those flabby globes of power and then use the aura spell to again push her cheeks together and bring the building crashing down, much to her delight – she giggled as she imagined her butt crushing the building, but not only that, how she would feel as her flank spread itself around the building as she increased her size yet again.

The panties had not been forgotten, once again now wedged deep within the canyon that was her buttocks they pulled tight against her flesh. Twilight could feel the soft material pressing up against the inside of her cheeks and she delighted in the feeling. She could feel every little movement her huge butt was making as it expanded more and more, covering them with its generous size. With what little movement she had left she shifted her weight slightly backwards and felt her butt move backwards and dig a little into the panties, which held fast thanks to her previous spell. She began ever so gently to rock herself back and forth, aided by the fat now building up in her into a rhythmic motion and each time she rocked herself, felt the panties dig into her enormous rear end. Each time it did it was ecstasy, the feeling of the material rubbish up against her butt sending it into an appreciative ripple of delight as she rocked herself. Backwards and forward….backwards and forwards. Each rock brought forth greater pleasure and Twilight was almost ready to give over to the feeling, until she felt something hard against the inside of her flank on its outermost limits. She had been continuing to eat during this time and obviously continued to get bigger and bigger. She had finally reached the outer wall of the poor building that was doomed to be crushed beneath her.

Not wanting to give up the incredible pleasure she was feeling from the rocking, Twilight continued to rock her body back and forth as her butt expanded itself around the building. Not only now was she experiencing the divine feeling of the panties digging into her rear end, but her ginormous globes of ass were rubbing their way along the outside of the building. It was getting all too much for Twilight who rarely felt such carnal pleasures and she began to moan to herself as she continued to sway back and forth. A low moan at first but as her ass expanded further and the more of her enveloped the building, she moaned louder and louder. To increase the pleasure she found the panties wedged deep within herself and grabbed them with the aura spell. She was now so large that even with the shadow of her butt she was starting to sweat more and more, and found that most of it was starting to pool down the crack of her butt and wetting the garment. She grabbed it and started to work it, up and down, up and down, rubbing it against herself. The double entendre of using the panties to spur herself on and wrapping her whopping cheeks around the building and rubbing up against that was quickly causing a sensory overload that soon threatened to overwhelm her. Should she loose herself to the moment or hold out until that building was well and truly crushed, with only splinters remaining. Perhaps…she could do both.

Like before a risky move but one that would satisfy her immensely, Twilight once again picked up the pace and ate at her absolute limit – the food stock now half gone but with plenty to spare, cakes disappeared into her at an incredible speed, almost becoming a blur. She was expanding so fast now it was hard not to notice her advancing size as she overtook the top of the building she was about to crush. All this time still rocking herself, rubbing herself with the panties and feeling the building pushing against her.
