The next chamber came, and Chell could feel the weight packing on, though still it wasn’t enough for her to be deterred. It was in this chamber she finally acquired one half of the Portal Gun, which could only fire one portal at a time. After making her way out, she found the next cake, a double-layer chocolate and peanut-butter cake with whipped cream on the rims again. Chell swallowed it all down as well, feeling her stomach churn and expand.
GLaDOS’ words did indeed come true, the more tests she completed, the bigger the cakes would become. She could feel herself growing heavier as well, her jumpsuit stretching out, a huge gut hanging below her waist and jostling with every movement. It almost felt good, being so huge and soft, after she finished a cream-filled triple-layer wedding cake twice the size of herself she couldn’t keep her hands off her giant, jiggling body.
GLaDOS even commented on her while she was slapping and jiggling her fat gut, watching it sway back and forth like a pendulum made of gelatin. “Look at you, such a tiny little glutton. Eat any more and we might not be able to test anymore.”
Chell giggled, waddling her way over to the elevator, her fat ass plainly visible through the jumpsuit.
“Such a large appetite for such a tiny girl… I wonder how long you can keep this up.” GLaDOS pondered.
Another test chamber came along, and Chell found herself waddling up towards it, her body becoming heavy from all the cakes she’s been devouring. Her arm struggled to fit inside the portal device, but it seemed to wrap around her meaty hands quite well, albeit uncomfortably. To her right was a large drop, with staircases leading to the bottom, and a portal surface on the ground. She looked down, and then up, there seemed to be a platform on the wall that was pointed towards an elevated ledge.
What Chell had to do was simple, and even with her weight, it seemed easy enough for her to accomplish. She placed a portal at the bottom, and a portal on the wall surface, and hopped down, feeling the wind soar through her jiggling fat folds… Until she felt a heavy WHUMP!
Chell wiggled from side to side, her fat body barely moving at all. Looking up she saw her fat, childish booty hanging from where she placed the portal, as well as her thick, dangling legs. She placed her arms on her obese sides, making a pouty face. Chell tried to squeeze herself out of, or through, the portal, but found no such luck.
Being in an obviously stuck position, GLaDOS had no choice but to intervene. “It appears as though your expanded size is no longer able to fit through standard-sized portals. Though it is unprecedented, I am forced to increase the capacity at which your device is able to fit heavy objects through.”
Chell was slightly confused, but GLaDOS clarified soon after. “In layman’s terms, you’re so fat you cannot continue the testing. So I shall make the portals large enough to fit a whale, an animal more befitting your current stature.”
Soon the child test subject felt the portal expanding below her, and her fat body flowed through with ease, and was able to resume the puzzle. Though this was a bit of an alarm for her, as she realized just how big she was getting. Nearly eight hundred pounds of blubber, somehow still mobile… And hungry for even more! Could it be that syringe at the beginning of testing had some adverse effects on her hunger?
Chell continued testing as normal, yet this time when she reached the end she was determined to ignore the cake, no matter how delicious it was. No matter how loud her stomach growled, no matter how tantalizing it seemed, she couldn’t let herself get any fatter! Not just for the testing, but for her own sake as well.
Yet no amount of preparation could prepare her for what she saw… Two cakes. Each of them just as fattening as the other, and Chell was just unable to resist. The drool dripped from her mouth, her eyes glistening, she dashed her fat body over and began swallowing them both down by the mouthful, her orange jumpsuit stretching out it’s very limit, yet still holding onto her body tightly!
“Mrrph… UUURRRRP!” Chell belched in the middle, thinking to herself how amazing all of this was! She didn’t care how big and fat she became, all that was on her mind now was endless feasting and gluttony. As soon as she finished that cake, she was on her way to the next one, twice as fat and twice as eager to complete the next chamber.
More chambers were on the way, and her body just kept growing larger. Eventually GLaDOS had to use a robotic crane to lift up Chell’s immense body after she broke the elevator’s weight limit. A feat GLaDOS didn’t think possible with one human, let alone a human child.
As she waddled into the next chamber, Chell was faced with a new threat. GLaDOS was eager to explain. “Given your size, this next test may prove too difficult for you. You’ll be a bigger target for these Aperture Science Military Androids.”
Chell was a bit afraid, but was able to squeeze her way through the door and find the first Turret, back turned to her and pointed into a corridor. While it was already a simple solution, Chell got a bit… Creative with it.
With a heavy bump of her booty, she sent the turret flying down the corridor, watching it soar through the air and smash into the wall with immense force. Waddling down the corridor, her fat body bouncing and jiggling around with confidence, she found another turret, and with a quick portal below it, she was able to drop the turret down and watch it collide right into her belly, which she bumped back so hard it rammed into the ceiling. Chell giggled, happy she finally had some use for her obesity during these tests!
“Quite an unorthodox and unnecessary amount of creativity.” GLaDOS mentioned. “At least your gluttony has paid off… Somewhat.”
A room filled with three turrets was soon entered by Chell, each surrounding a button she needed to open a door to the exit. She couldn’t as well just run in and booty bump and belly slam all of them, so another plan was hatched. She placed a portal on the ground, and a portal just above the center of where all the turrets lay.
With a deep breath, Chell leaped into the portal in a cannonball position, slamming her fat ass right onto the button, the shockwave knocking all the turrets into the wall, leaving a crater on the ground and breaking the button so that the door was permanently opened.
GLaDOS, despite the neutral voice, seemed quite genuinely annoyed and impressed. “You keep finding new ways to surprise me. But please try to refrain from breaking any more vital testing apparatus.”
It was undoubtedly a miracle Chell was able to move at this point. After making it to the final chamber, her body was an immense heap over over 2,000 pounds of blubber, hardly recognizable as human anymore. She was breathing heavily, burping constantly, still stuffing her face from the last practical feast of cakes she had at the end of the last chamber.
“EEEUURRRRAAAAPPP!!” Chell exhumed, looking around herself. There didn’t seem to be any portal surfaces, no obstacles, no challenges of any kind. She raised an eyebrow, wondering just what kind of test this was supposed to be.
GLaDOS’ voice chimed in again. “Thank you for participating in this Aperture Science Enrichment Center activity. While normally, this would be the part where we dispose of you in a humane and painless manner, we have decided to take care of you in a more special way. Consider yourself lucky.”
Suddenly, the walls opened up, lowering into the floor as Chell was greeted by several MILLIONS worth of cakes, each one taller than skyscrapers, filling deep into this endless room of wonder!
“Enjoy your endless feast while we continue testing on other subjects. We will cease further communication and allow you to enjoy your cakes as much as you please. Thank you again for assisting us in the further enrichment of science. Goodbye.”
With that, GLaDOS signed off for the final time, and Chell was left all alone. All alone… With all these cakes! She waddled over and dove into them, swallowing them one one after the other, scarfing them all down like a ravenous beast. “Mnrphm… BRRURRBP! Nomph… URRRP!”
Chell could feel her body expanding rapidly, swelling out even larger than before, now finally ripping out of the jumpsuit that held on desperately for so long. She was in heaven, handfuls upon handfuls of chocolate, vanilla, peanut butter and various other flavors of thick, mouthwatering cake! It was all so euphoric, she could just feel herself sinking deeper into this endless sea of frosting and filling, drowned in both desserts and adipose, only left in a pair of underwear and a bra to cover up her flabby breasts.
She was a long way from filling up even this entire chamber, but she knew eventually it would happen, and besides, it wasn’t as though she were in any rush to escape anyway. This was paradise, she wouldn’t mind if she kept eating like this for the rest of her life!
And it seemed like she would, as the serum she had been injected with permanently trapped her in the body of a 5-year-old, as many weeks, months, years passed without so much as her taking a break. She constantly stuffed herself with cake, now larger than an average two-story building, still growing larger every moment!
“Mmruuugh… BBUUUURRRRP!” Chell belched, sliding another entire cake down her throat pitifully. She was becoming weak, tired of feeding herself. It was around that time that she noticed a tube coming down from above, it was far larger than her mouth and yet it still managed to squeeze it’s way into her gullet, pumping in huge bulges of cake batter down her greedy throat.
