Kaolla had looked forward to this, everyone else was going away for a long vacation so she would have the whole in for herself. She wanted to spend time in her lab and work on the next Tama-chan and just play around.
"We're leaving now!", Shinobu called from the hallway.
Kaolla woke up from her day dream about Super Mecha Tama-chan and rushed out to say goodbye to her friends.
"Itterashai!!!", she screamed as she crashed in to everyone and their luggage.
"Not gonna miss that... Are you sure you will be ok by yourself?", asked Naru.
"Daijoubu!", Kaolla replied with her usual smile, "I got things to do."
"I left food for you in case you get hungry, it might not be very good though...", Shinobu said quitely.
"Tss, your food is always good! Arigatou ne ~ Bye bye now!"
"Bye bye!", the all waved to her as they walked towards the stairs, "Take care now."
"You too."
She turned around and went back in to the house, quiet.
This is so nice, she thought as she walked to her upgraded lab. She sat down by her desk and started to draw some sketches of new weird machines.

After a while she found that she was lacking inspiration, they were all to similar to the old things she had done. Her stomach growled, it still had been quite a while.
"Time for dinner!".
She had some food in her room, well, not some, actually alot. She shoved the  sketches away and brought out half a feast. Pasta, chicken, sallads, bread and on of her favourite dessert, a chocolate cake. Bored by the silence she turned on the TV and watched as she ate.
She loved food, that was not unknown to people. Keitaro still hasn't forgotten his first harsh weeks at the in when she ate all the food he prepared. And her metabolism, wow. She ate for three and always managed to stay skinny anyways.
She had finished off the main dishes and felt the skirt being a bit tight.
"No good in being uncomfortable when you eat" she thought and got changed to a bigger pair of pants and also changed her shirt for a nice turtle neck. She could see a little bump on her tummy.
"Hehe, not even finished yet"
The chocolate cake's frosting nearly glittered and she felt her mouth watering. She took a spoon and began to eat. It was a nice movie on so she didn't really think of all the bites she took. She felt a little strain around her belly and placed her non-eating hand on top of it and rubbed it. This was the best part of the movie. She started to eat faster.
The movie ended.
"Haha, that was a good one!"
She stretched a bit and tried to tug down her sweater but it wouldn't go all the way down. She looked down to found a quite round belly, she poked it and noticed that she had actually eaten the whole cake.
"Wow, I was gonna save half for later..."
As she got up she felt how full she was, she liked it. It was not like she hadn't eaten more than that before. Smiling, she placed both of her hands on her belly. She would usually take a nap after her meals and then her metabolsim would do it's thing. If only it could always feel as nice, being so full and satisfied.
If only... Actually...
She sat down again and moved to the computer. There she started to calculate things, ingredients, stuff you and I don't normally do. She got up and opened a locker where she had chemicals and other stuff and started mixing some together. After a few minutes she was done and had a glass full of liquid.
"This should be it, I guess I'll test it"
She gulped it down pretty fast and since she was tired and it had gotten pretty late she decided to go to bed. She changed to her pj's, climbed up to her loft bed and turned out the lights.

Next morning she woke up pretty early like she always would, she got very hungry in the mornings. She climbed down and yawned slightely putting a hand on her belly as she streched.
"Huh.."
She lifted the cloth of her pj's to expose her belly and found that what was there last night still were.
"Yatta!" she thought and got dressed for breakfast.
She actually still felt pretty full but still had her usual appatite. She ate her steady breakfast and found the turtle neck sliding a bit further up. She giggled.
She kept doing her thing, sketched, relaxed, ate, slept.
On the third evening after supper the potion was still active. The turtle neck had curled up and her belly was exposed pretty well. She looked about as round as if she would be having a baby any day. She didn't mind, she actually didn't really think about it at all since she was working on other stuff. Changed in to pj's she had to unbutton most of the lower buttons to fit in it. She climbed up to bed finding it a bit harder than usual since she was obviously both bigger and heavier. She turned out the lights and went to sleep.

She woke up, hungry as ever. Having made a bigger shirt the day before she put it on and tugged it all the down.
"That will keep it warmer", she said as she went to get breakfast.
"Ah, already.."
The fridge, freezer and pantry was empty.
What to do now she though. Her stomach gurgled loudly.
"There, there..", she said while stretching out her arms and patted it with both her hands. Then she remembered, Shinou's food!
She took a sprint to the kitchen, her stomach groaning from the sudden movement. She slowed down and put her hand on on it, she had never felt this hungry before, it was like she had alot more to fill up than usual. Having not moved around much the last couple of days she discovered the extra weight around her waist. Her stomach groaned loudly once again for food.
"Yoisho..", said with a bit of effort as she put her hands under her belly for a bit of extra support as she walked down the stairs.

Finally she made it to the kitchen and as she opened the fridge and the pantries she was not dissapointed.
"Shinobu, arigatou!", she said happily as she started to take out dish after dish, heating them up and placing them on the table by the sofa in front of the TV.
She sat down with her stomach rumbling slightly. She looked at the food she brought out and found it to actually be all that Shinobu had made for her.
"Haha, I guess my stomach was talking a bit too much for me to think straight. Oh well, I'll just pack away what I don't eat".
She looked around for what to eat first, there was a mountain of pasta and a huge caserol of meatsauce. She poured the pasta in and mixed it as she turned on Incredible Machines. She slurped down the pasta in about 10 minutes. She exhaled.
"When will Shinobu understand that her cooking is in star class."
She looked hungry around for next dish. There was a turkey, mashed potatoes and the lot. A bit weird she though, not really season but who cared, still yummy. She cut bits and pieces and spooned up mashed potatoes bite after bite. She felt her pants getting tighter but didn't really mind, she was too hungry. She kept eating. The turtle neck once again sliding up towards her gut. As she finished the turkey she felt a slight pain. A big inhale and pop! There went the button on her pants and her before restrained stomach swelled a bit.
She paused and tried to scratch around her belly button but found it too far down. She grabbed a fork and got what she wanted.
"Ahh..", she leaned back a bit smiling and then looked up again.
There was still so much more. She licked her lips slightly wondering if she should continue. Not thinking more than a few seconds about that she grabbed one of the 5 different pies. She had eaten alot before, no worries, she thought. One pie, , one more and another, soon they were all gone and she moved to the big sallad with bread. She didn't really pay any mind to the TV anymore, the food was even more interesting than the new Robot.
She was getting big, not even remembering the experiment a few days ago. As she swallowed the last piece of bread she gasped slightly for air.
"Puh... I've never felt this full.", she looked at the table finding the other side still full with three cakes, four bowls of different cookies, ice cream and a huge bowl of fruit.
She moved her self towards the other side of the couch as she was to round to actually reach out for the treats. Her belly was huge, in the way for the table even, she could reach even if she moved.
Wanting the treats really bad now she forced herself up finding it very troublesome. Her stomach swelled out before her. She waddled to on side of the table and pushed it so it stood in line with the end of the couch instead. With her back aching a bit, she happily sat down on the couch again.
She grabbed the bowl of fruit and the one with the ice cream. She started eating the together, stuffing herself more and more. Her stomach groaned and having little experience with limits she kept going on the cakes. She lifted them down to the floor along with the cookies and put her legs up on the couch to lie more comfortable. After the second cake there was stings of pain running through her stomach, the turtle neck curled up as the day before her belly rose, swollen and round. She breathed heavily.
"I... I've eaten like this before... I won't lose to this!"
With one hand firmly on her tight aching belly she kept going. There was a slight trace of sweatdrops on her forehead as she forced down the cookies to the full belly. It groaned a gurgled in a almost crying tone. The last cookie went down.

She breathed heavily, feeling exhausted.
"Hah.. Ha.. I.. I did it..", she said with a slight smile but was interupted by the stabbing aches and moaned loudly. Her belly had expanded to such a massive size, it rested against her thighs and almost down to her knees. Her skin was streched and slighly red from the strain and struggle.
With some effort, she stretched her arms out and rested them against the belly. Squeeky noises, almost like a whining dog, was all she could utter. She felt like she was going to burst.
"Now.. A nap, and I'll let it all digest, can't do anything else...", she though and closed her eyes.
Never had it taked so long to fall asleep before. The belly kept rumbeling, the pain came and went.

The next morning she woke up alot later than usual feeling very heavy somehow. She rubbed her eyes and looked up.
Her jaw dropped.
She was full, just as full as yesterday. She clasped her enourmus swollen belly with her hands as far down as she could reach.
"I.. I look like I drank a swimming pool!", she said with tears in her eyes.
In all the thoughts running through her mind and she stroke her still sore belly the right one finally showed.
"The potion..."
