Christine let out muffled fart underwater, sending bubbles with an awful smell up to the surface.
"Where the hell come from?" Christine said, still clutching her stomach. More farts came up to the surface, filling the room with the awful scent. She continued to grip her stomach until something odd on her stomach. A bit of softness was growing there, but she was distracted from the smell coming from her ass. Bubbles continued to rise faster and faster and in larger quantities. Even the water started to get a bit warmer.
"Oooh *ppphhhbbbttt*... I don't feel so hot *bbbbrrrrpppp*... and how am I this gassy *pphhrrtt*?" Christine whispered to herself. Her body was still bloating a bit, leaving a slight pudge to her stomach along with a bit more softness all around. Meanwhile, her already big boobs grew bigger and fatter while her ass grew thicker and rounder. Suddenly her stomach felt a sharp stab, causing her to grit her teeth and grunt. Slowly, a thick, brown log was coming out and rose to the surface.
"Ew! *ppphhhhrrrrtttt* Oh god, I think I feel more..." Christine clenched her buttcheeks until she noticed something odd about them, as if they were a bit heavier. She nervously reached down to see if it was true and sure enough, there was a lot more cushion than there was before. Needless to say Christine was shocked and was visibly in panic. Just to be sure, Christine felt her body a bit more, feeling all the curves she had gained. Of course, this turned her extremely on. She moaned in delight and nearly lost all control of her body. The shit she was holding in came out in a burst but slowly became a stream of both wet and solid waste. Her piss started to come out as well, causing even more pleasure from letting all out. The water was already turning into a brownish-yellowish hue, which reeked even more. Christine snapped back to reality when a bit of it went into her mouth and spit it out.
"Oh god... *pbrrrrrrbbbttt* what's going on to... *ppphhbbbtttt* me? It... *bbbbbrrrrrttttt* must be that cream! I need to... ngghh... I think it's starting... *BBBBRRRRTTTT*..." Christine whimpered. She felt her body swell even faster, her stomach bloated outwards and her ass started reach the sides of the tub. Her tits started sag from all the fat it to hold, even lactating a bit. A chin was starting grow outwards while her fingers started thicken up to the size of sausages. Meanwhile, she lost all control of her bowels and poop and piss just came nonstop. She tried to hold it in but all that did was cause a huge buildup to occur, releasing all out like a nuclear bomb. What was worse were her toxic farts. Her stomach grumbled as it worked harder and harder to release all of it. It smelled like hot vomit, rotten garbage, and skunk spray multiplied by 10. Christine couldn't take it anymore and vomited all over herself. She could feel all the crap build up to her knees, in which her constant growth didn't help.
"Nggghh... *PPHHHBBBBTTT* I feel so... *BBBBBBPPPPTTTTT* heavy..." Indeed she was right. At this point Christine was the size of bbw and continued to grow faster each passing second. She tried to lift herself up but her massive frame and weak arms didn't allow her. Her ass started to pile up and her legs were thicker than a jug. Meanwhile her bulbous belly was as big as beach ball and tits that reached to her waist. Up at her face, it started to appear much rounder and her neck started to thicken. Christine's whole body was covered in the sewage water, spilling out of the tub from the space being taken up by her own waste and bloating body. Her body churned and groan in despair.
"So much... *PPPPPHHHHHHTTTT* fat... *BBBBBBRRRRRTTTT* and crap...* Christine said. At this point she just couldn't stop her bowels. She even tried to block her holes with her own hand, but one, it was very painful, and two, it only lasted for 10 seconds as her body forced it away. Christine was past being an ssbbw now and was definitely stuck inside the tub. All the poop reached her massive stomach, which was growing even faster. Her stomach reach the side of the tub and her legs were getting even tighter down there. Christine groaned in pain as her body was forcing it on to the sides. At this point her entire body was spilling out of the tub like the septic liquids she was producing.
It wasn't until 2 minutes in which the growing finally stopped, and her anus and vagina could rest. Somehow, under all that pressure of fat, the sides of the tub managed to hold all Christine in, with multiple cracks of course. Meanwhile, she was suffocating under layers upon layers of thick fat. Her stomach was bigger than her toilet, with legs nearly just as big, her arms could probably over flow the stink, and she had boobs that were as big as her arms. Stretchmarks and blue veins were very visible on her skin along with cups of sweat that dotted the surface. Her face looked more like a fatty upside down tear mark, with her saggy chin being the tip and cheeks that popped out which could probably fit a few baseballs. Christine tried to feel what she could with her fatty arms, slightly aroused by the process. Her hands sunk deep into her body while also creating a gurgling sound.
But of course, her skin was soft and smooth. "Soft and smooth..." Christine grumbled along with a few other silent complaints. Although she was very annoyed with her current being, a small part part of her enjoyed the feeling of such softness and immobility. Christine realized this, blushed a bit, and continued to try to pry herself out of her predicament. One jiggle at a time.
End.
