Things had been quiet in the TARDIS for a while.
The Doctor and Rose hadn't gotten too many reports of world ending threats throughout any of time and space, so they ended up having lots of free time to just lounge around on the TARDIS and discover the many nooks and crannies around the infinitely sized time machine.
During this time, Rose discovered how the kitchens were almost always stocked with all kinds of food. This allowed her the chance to really discover the full range of tastiness from all the different eras or locations throughout all of time and space.
This in itself was both a blessing and a curse.
With a full range of food delicacies available through the TARDIS kitchens, and no crazy problems that constantly had them running for their lives, Rose got the opportunity to stuff her face with as much of the food she wanted, and as often as she wanted to.
Which is what caused her to outgrow her favorite jeans.
Rose huffed and puffed as she kept tugging and yanking the pants up her thicker legs, surprised and confused about why they felt much more different than before.
Of course, the reason was pretty obvious. She had put on a pretty noticeable amount of weight, and its affects were seen pretty well throughout her body.
Her face had expanded a bit, softening her cheeks a bit and making the slightest double chin appear when she looked down. Further down, her breasts had noticeable expanded, growing one or two full cup sizes, straining her bras and making them much more tighter on her, something that she had noticed, but had no problem with whatsoever. She had never exactly been the most... gifted in the chest before.
Of course, her breasts wasn't the only thing that had expanded. Those melons hung down a bit when they were unrestrained by a bra, lightly grazing the new belly she had grown for herself. Her stomach had expanded, growing from it's slender, toned form into a pot belly that stuck out an inch or two from her torso, hanging down a bit as it slowly started to cover the waistband of her pants, which is part of what made her pants so hard to button.
Of course, the main culprit behind her pants not fitting was Rose's lower half.
Her ass had swelled up quite a bit, growing from its toned, perky form, quickly reaching ghetto booty size. Each cheek was nice and plump, quite a bit bigger than they used to be and gaining the slightest hint of cellulite.
Attached to that butt were her thicker thighs, which had swollen and plumped up to the point that they were now thicker and bigger than her arms, getting close to being Thunder Thighs, since they had started to rub together when she walked, as little as that tended to be.
As mentioned before, Rose was having a difficult time putting her jeans on, due to the new size of her thighs. She managed to get them up her thick legs, put now she was having a problem pulling them up over her plump butt cheeks. It took a lot of struggling and hopping in place, both of which caused much of the flab making up her body to jiggle, but she eventually managed to force the jeans over her plump ass, huffing out as she finished the arduous task.
Then came for the next one, actually buttoning the jeans.
Rose grabbed both folds of her pants and tried pulling them towards each other, struggling when they came to a stop with a full inch still separate from each other. The English Blonde cleared her throat, then took a deep breath. She sucked in her stomach as much as she could and pulled the folds of her pants with all her might, moving both components of the button towards each other. It was difficult, and made her pants incredibly tight, but Rose managed to push the button into the hole. She sighed out in relief at having finished her difficult task, and followed it up by zipping the pants up, making them even tighter than before.
A curious frown on her face, Rose moved towards the mirror in her room to see what the problem was, and stepping in front of the glass presented her full weight gain to her in a pretty drastic way.
Rose had currently been preparing to get dressed in a simple outfit since she was pretty sure they wouldn't be on another adventure today. She had just gotten her jeans on, but hadn't done the shirt yet, so she was still just in a bra.
This allowed her to see how much she had changed. And boy, was it a lot.
Her breasts were nearly overflowing her too small bra, pulling it incredibly tight on her body and pushing them up towards her face. The tight form of her jeans made her belly into a muffin top, flowing down around her as she started to get love handles around her torso, making her appear even more fatter. Her jeans looked incredibly tight on her legs, and when she turned and looked at the back to see her butt in the jeans, it looked like they were pretty close to tearing.
"Hm," Rose hummed in thought, realizing the true length of her gain as she turned and looked in the mirror again.
After another second of thought, Rose just shrugged her shoulders and moved to grab her shirt, not caring that it was probably too small, as well.
She had been enjoying all the free time they had on the TARDIS recently, and was really liking all the food available in the kitchens. Why should she put a stop to that just because of something as insignificant as her weight? There was no one around to judge her, so why should she do anything different?
Of course, the topic of Rose's increasing weight would come up again soon. That ended up being because...
