"C'mon, just tell me what it is already!" she groaned, her paunch of a stomach growling as he unlocked the door. "Don't worry, you'll know soon enough. Hopefully it will make that stop." She raised her eyebrows, slightly blushing. "Oh?" He chuckled and opened the door.
Inside was a single chair and some rope, with a camera positioned towards it. He stepped behind her and whispered in her ear. "Happy birthday, babe!" She slowly stepped towards it, her breathing heavier. Her thighs and belly jiggled with every step, making her t-shirt and shorts work overtime to keep them adequately covered. "Why the hesitation?" She paused for a second and then sat down. "Good, now stay still," he said, tying her hands together and her feet to the legs of the chair. They then fastened her hands in a way that allowed her to touch her belly, but nothing else. "Ready, love?" She nodded and he scuttled off.
He returned from behind her with a table, and then left again. He very shortly returned with three pizza boxes, stacked on top of each other, and a two liter of cola. They sat them down and opened up the first box. "Now, open up fatty. I haven't got all day." She complied and allowed him to start feeding her. She ate quickly and sloppily, quickly plastering the tops of her tits with small bits of cheese and crumbs.
She got down the last bite right as a burp forced its way up her throat. She moaned and rubbed her now slightly larger belly as he opened the next box and brought the slice to her face. "Come on now, you sloppy fucking pig, open up. Now." She gave her full belly one more rub before opening and biting down. She was starting to have slight difficulty with breathing in fully, and her pants were starting to strain. New stretch marks, not that she didn't have any before, had begun to appear ever so faintly at her flanks. Between the growing bulge at her crotch and the growing orb above that, they weren't gonna last much longer.
Sure enough, the button popped off four slices in. She took the moment of respite as they sat the slice down to rub her belly. She now sort of looked pregnant, the skin of her gut looking slightly swollen and tight. "Thirsty?" he asked, putting a funnel down her neck as she moaned. He uncapped the bottle and started pouring. She swallowed as fast and as hard as she could, attempting to finish it before she needed to breathe. Her stomach swelled out faster than before, quickly growing tight and shiny from her sweat. The stretch marks began to spread, inching towards the apex of the metaphorical balloon attached to her. The bottle finally ran dry as it nearly reached her knees.
He pulled out the funnel and she let out a short burp, before stifling it. Her belly continued to swell, the gases expanding inside of her. "Let's take a break for a minute and see if we can't help relieve some of that pressure, eh?" He pulled her shirt up above her breasts and started rubbing her gut, instantly starting a chorus of groans and burps from her. It slightly deflated as he moved further downward and rubbed the bulge underneath her nearly see-through panties with his second hand. "I'll take care of this later, don't worry." He smirked, leaning up and kissing her before picking up another slice from the half empty box. "Open up, my pretty little whale~"
She started eating again, much slower than last time. They rubbed her belly in between slices and frequently rubbed her down there as he fed her. She finally finished the last slice and groaned as she rubbed her now massive stomach. Her belly button was now shallow and it was nearly touching her knees again. Stretch marks now reached completely from her sides to her navel and intensified by the second. She was having trouble breathing, partially from her stomach obstructing her lungs and partially from not wanting to put too much pressure on her overtaxed balloon of a gut.
"Alright, just one more box to go!" he exclaimed, opening it and reaching for another slice. "Wait, please..." she mumbled. "Too full, gonna *uuuurp* burst if I eat anymore. I'm sorry," she said, before letting out another burp. "Nonsense, you can do it!" they said, holding the slice up to her face. After a moment of hesitation, she opened up her mouth and bit down.
Each bite had a noticeable effect now, making it swell up slightly each time. She moaned and burped in between bites and now constantly rubbed her belly in a desperate search for relief. He now had to reach and lift up her belly to rub her panties, and she was now dripping clear from the head of it. Her gut reached her knees by the slice, and would've been drooping over them by the seventh if it were not for how tight it now was.
"Come on, just one more. For me?" he pleaded as she shut her mouth tight. She was so full, too full. It felt like she would burst at any second. She literally had to watch how big her breaths were to prevent her overfilled tank of a gut from splitting at the stretch marks that were now dark red. The area around her belly button had started to turn a shade of pink. He finally reached down below her belly and into her panties, beginning to play with her balls. She began moaning and he shoved the piece in her mouth. She bit down and swallowed, groaning and burping immediately after. Her belly swelled forward again, the shade at her navel growing darker. She bit again, swallowing a bigger bite this time. It lurched forwards again, her belly taking on a pink hue in its entirety, the apex turning red. She took the final bite and swallowed, and she was doomed.
Her belly had been loud for a while now, gurgling and burbling as it struggled to digest her massive meal, but it now let out a massive groan and began creaking as it swelled uncontrollably. "W-what's *uuuuuuuuuuuuuurp* happening to m-m-me?" she asked in a panicked tone, attempting to reach the front of her belly to attempt to soothe it. Even without the restraints, this would have been impossible to do. He chuckled and smirked, putting faith in the gut as it quickly lost the fight against the pressure inside. It was massive, beyond human proportions, so massive that it split the arms clean off of the chair. "H-h-help *uuuuuuuuuuuurp* me!" she weakly shouted as her lungs lost almost all room to expand.
The creaks and groans grew more and more intense, until finally he stood up and slapped the gargantuan orb in front of them. She squealed as the slap reverberated across it. Her belly button popped out into a marble sized ball as her belly finally stopped growing in size. It had run out of elasticity and now the pressure was increasing in size. The skin continued darkening and her belly button slightly swelled. It began vibrating as the stretch marks grew thin enough to see the outline of the overtaxed organs inside of her. Her boobs and thighs jiggled from it as her eyes crossed from the pressure inside.
"C'mon, cut it out. The eye crossing is a bit over dramatic, don't you think? You'll be fine, I'm gonna untie you and take you to the bedroom, if you can still fit in there, and pamper you all night long. How does that sound?"
The pressure continued growing, before all at once the vibrations stopped. Her eyes uncrossed and she looked at him, opening her mouth to speak. "I really thought I was going to-"
A creak, followed by a dull wet pop from inside her interrupted her and the doomed belly lurched outwards again, some of the stretch marks splitting open and spraying blood onto him. "Don't just fucking stand there, help me!" she screamed, pressing onto the little bit she could reach to attempt to stem the flow. "Oh shit. Oh fuck. Just stay there while I get a doctor. I think you've overdone it tonight," he said, turning around and dialing his phone. It lurched again, followed by another cacophany of pops, and the stretch marks split wider, allowing fat to squeeze out of them. Her shredded organs began leaking out too, along with some of the partially digested food. She screamed unintelligible words and they turned around, gasping and dropping his phone. "Oh my god, I am so sorry. I should have listened."
Her belly now reached a whole two feet away from her knees, and a pool of blood, fat, ruined intestines, and mushy pizza was forming around her. Her face was now partially obscured by her tits and pale from fear and blood loss. She let out one final muffled scream and arched her back as her skin gave up. In nearly an instant, her belly's skin was shredded and all of her insides were on the floor in front of her.
Her head fell, her teeth now stained with the blood that shot up her throat. Now unobscured by her breasts, the look of pure agony on her face was revealed. He fell to his knees and vomited, before passing out face first into the pile of organs in front of him.
