It had been two weeks, but Teji still had not fully grappled with the idea of becoming a sentient mass of mana. Keeping her normal appearance had become more and more of an effort as the slime’s toxin spread through her system. Of course, like lycanthropy or vampirism, there was no cure unless she managed to secure some kind of divine favor.

Which is why she had taken matters into her own hands. If she could gain more mass, she could keep her body stable. She felt that protein was probably the easiest way to do that and milk was likely the simplest method. The bottle was cold in her hands as she stood in front of the convenience store fridge.

Not sure what else to do, she threw her head back to drink it down. The fluid slid down her throat with ease. Her tan skin flickered purple as the slime nature of her body began to react.  Her grip on the plastic grew tighter, her gulps grew more forceful. Her shoulders bulked up first. They felt ridiculous on her tiny frame, but she had a feeling she would not be tiny for long. With the first bottle already empty, she could tell the protein-packed liquid was doing its job. She went for a second without hesitation.

She gulped eagerly, milk running down her cheek as she guzzled. Her muscles seemed to explode with power, as biceps inflated like they were being pumped full. Her skin went translucent as what remained of her humanity was strained even further. She watched her forearms balloon outwards, their gelatinous nature showcasing the of amount milk swirling through her system.

It seemed like this was having the opposite effect!

Perhaps one bottle at a time was not enough? Cracking open two more she shoved them into her mouth, stretching it out. Chugging as if her life depended on it, she felt the power growing in the rest of her body. Her core muscles had grown more defined through the first two bottles, but now they pulsed with each gulp.

All of a sudden her lower half lost control and she dropped into a puddle of herself. Desperate to regain her shape, tendrils of purple mana coiled around other bottles. She crushed them in her grasp, letting her monstrous body absorb the protein directly. Slowly, bit by bit, her body rose out of the mass. It was like she was wearing a mermaid dress as she staggered to her feet once more. Her new weight made the floor crack, each step sounded like the roll of thunder.

Curious, she focused on that mass and thought about it being somewhere else. Almost at once her muscles faded away as all of that bulk moved to her chest and a pair of astonishingly large boobs blossomed. The strain was so great that they melted back into her, the mass returning to her muscles.

She toyed with the idea of drinking more. She wondered what that would even do to her. There was really only one way to find out and if she ended up huge? Well, that would not be the worst thing to happen this month.
