Getting an idea, she twirled her wand and smirked. Her stomach fat sank back into her body, breasts went back to normal, and thighs a little less round. She smugly thought a fix had been found for unwanted weight. Unbeknownst to the magician, the forgone fat will reappear on her body and this time it would be here to stay - even if she tried using magic or some other means. Still, the girl was free to use the spell whenever she wanted. She did find out that even with the fat gone (for now), she was just as hungry when she had it.
"Oh well," she chirped to herself, "I can just cast a spell and it'll disappear!" This only encouraged her to eat more and larger portions, and made her more daring to have treats she believed were too unhealthy. Her confidence that she could never get fat only led to a downwards spiral of gluttony. How long this will last is unknown (except maybe the reader).
A few days passed and already her belly was pushing against her outfit. DMG stopped slurping on the thick chocolate shake tucked in between her breasts and was embarrassed to see her fattened bosom had less space to be confined due to her stomach taking increased space within her strained costume. Deciding to expand her costume, she prepared a spell to increase the girth of the midsection. She cast the spell, but unfortunately for the poor girl, she had missed.
"Uh oh..." she mumbled, "I don't know what this is gonna do..." Right after she finished speaking, her belly grew inside her already filled outfit. It grew heavy in her lap, having to spread her legs for room. It crawled underneath and over the table, desperately seeking for more room, the growing mass pushed the chair she was sitting in back when it found no further space. Her greedy gut taking up all the space caused her shirt to be pulled down, revealing her breasts which thankfully was covered by a bra, tight as it may be. Finally, her outfit snapped and fell to the sides, her huge belly heavily weighed down on her legs and chair, causing it to creek louder every second.
Dark Magician girl panted, out of breath, before attempting to rise which had her falling back on her seat. She groaned while exploring the new mass with her hands, it was actually really soft. Now that she thought about it, she was extremely hungry. It was at this time that Kuriboh came slowly walking in, struggling to carry a plate that had a whole cake on it. She quickly created a top to cover her breasts then looked at Kuriboh.
"Hehe um... magic accident," she laughed sheepishly. When he shot her a disapproving look, she crossed her arms. "Hey! Stuff happens you know." Reaching her arm down, she grabbed the plate and hefted it onto her expansive stomach. The dessert slightly sunk into the mass. Just when she was about to start eating, she grew worried that Kuriboh was tired from carrying all these desserts. "Can you get me my wand please..?" He left then returned with the wand. "Thanks," she pointed it at herself but before she could cast the spell, her hunger distracted her. What if I duplicate the food so Kuriboh doesn't have to carry so much anymore? Thinking and finding the appropriate spell, she cast it onto the cake, producing two large pink-frosted cakes. Bingo. She reached forward and grabbed a fork off the table. My belly's huge, it's covering my lap! Ultimately, she was unconcerned by this, knowing she could always get rid of it.
At first, she was slow to eat, savoring the sweet spongy delight, but with each fork-full she stuffed herself more and more. Her stomach seemed to be insatiable, she duplicated another cake along with her chocolate shake multiple times to attempt pleasing her gut. But she still felt hungry. After two hours of this, she had reached her limit. Frosting covered her lips and dotted her cheeks. She happily rubbed her dome of a belly, burping all the while.
