Taylor Kingston looked down at the small, white card box in her lap, staring at the chocolate-covered doughnut that lay inside, oozing slightly with custard filling.

    “So… I just eat the doughnut?” Taylor lifted her head, looking over at the scruffy-looking scientist flicking through her file. Being paid to eat a doughnut wasn’t exactly what she’d imagined when she’d first signed onto 2B Laboratories’ latest testing program. But then, Taylor considered, this was no ordinary doughnut.

    “Hmm…? Oh, yes, please.” Dr Grey shook himself a little, turning his attention back to the test subject before him, smiling warmly at her. “The dough is infused with serum, which will work its way through your body as you digest it. It’s made for your body weight, so you’ll need to eat the entire doughnut before you get the- er- full effect.”

        “And the serum is supposed to change my body-” Taylor began, looking squarely at Dr Grey for tells, any signs he was going to let slip exactly what the doughnut was supposed to do, but the scientist just nodded slowly, “and you’re still not going to tell me how, are you?”

        “Ah, no, I’m afraid not. To test properly, the subject needs to remain unaware of the full extent of the treatment,” he explained, setting down his clipboard for a moment. “We’re not just testing the physical changes but how you react mentally, and how your mindset might affect the changes themselves.” Dr Grey rubbed his stubble, face softening into a warm smile, apologetic but reassuring “which is a lot of technobabble to say ‘you wouldn’t want to ruin the surprise’.”

        Taylor nodded in reply, looking back down at the doughnut. She’d just about gotten used to the idea places like 2B Laboratories could seemingly effortlessly transform one person into another - seeing the inflatable people bobbing around in the pool was more than enough to convince her - but it still seemed bizarre that they needed her to test a doughnut. Then again, for the money they were offering, and the good it could do for her garage, she wasn’t going to ask too many questions. She reached into the box, lifting the doughnut out, powdered sugar coating her fingers. The sweet smell of chocolate and freshly baked dough wafting up to her as she squeezed the soft doughnut, some of the cream filling oozing out slightly.

        “Why a doughnut, anyway? And what happens if I don’t eat all of it? Will the changes just go straight to my thighs?”

        “No, no, nothing quite like that…” Dr Grey trailed off absently scratching at his stubble, gaze drifting to the ceiling in thought “at least, I don’t think so…”

        Taylor waited for the scientist to continue, Dr Grey pausing in thought, leaving her to try and guess what he was imagining.

        “Anyway, that’s what we’re here to find out!” Dr Grey quickly straightened, turning back to Taylor with a reassuring smile. “As for why it’s a doughnut, well, pills aren’t exactly the nicest things to swallow. Better it’s a sweet treat that causes the change.”

    “And it’s painless, right?” Taylor asked, the last nagging doubt slipping out, starting to consider the gravity of what might happen to her body.

    “Oh, yes, absolutely!” Dr Grey leant back against the testing room’s counter, setting his clipboard down beside him, grinning with pride, “I’ve spent the last few weeks making sure this change is as pleasurable as possible, though you know what they say about the proof of the pudding. I’m sure you’ll be fine, and I’m right here if anything unusual does happen.” His voice was confident, friendly, kind… doing a lot to put Taylor’s mind at ease.

    “Well, here goes nothing, then…” Taylor lifted the doughnut up to her mouth, pausing a moment to savour the aroma, imagining herself smelling just like it in a few moments. She took a bite, teeth splitting apart the chocolate coating, squashing and tearing through the dough, the delicious vanilla custard filling spilling out into her mouth. It tasted amazing! Taylor swallowed the first bite, quickly digging into the doughnut again, focussing on the texture of the dough, so dense and yet so fluffy.

    “Mmm, doc, it’s really good!” She managed to say, pausing between bites, imagining she could feel the dough slipping down inside her, the sensation of it settling down in her stomach. “Have you considered forgetting the science and just opening up a bakery?”

    “You’re too kind… but I have our kitchens to thank for that. I just threw together a few chemicals.”

    “Well-” Taylor continued, between bites of doughnut, “even if this doesn’t work out… at least I’ve had a delicious doughnut…” Something about the taste of the doughnut was addictive, or maybe it was the subconscious desire to be changed by it, but in a few moments Taylor was left licking chocolate frosting from her fingers. Already, her body was working to digest the doughnut, releasing the serum into her blood, carrying it through her body.

    For a while, nothing seemed to happen, Taylor staring impatiently at her reflection in the mirrored wall. She looked over her body, trying to spot any signs she was beginning to change, any clues for what she was going to become, little realising the first changes were beginning to happen inside her body.

    “So, how long does it usually take to begin?” Taylor asked, running a hand across her exposed midriff, wondering if she was just imagining the strange stirring feeling within. She was still wearing her usual work outfit, toolbelt and goggles included, the short jacket and tank top now quite covering her plump belly.  They were what she was most at ease wearing, after all.

    “Oh, well, depends on all sorts of things… how quickly your body digests it, your metabolism, heart-rate…” Dr Grey began, quickly sensing it wasn’t quite the answer Taylor was hoping for, “but I imagine you’ll start to feel it soon.”

    Taylor signed slightly, shifting herself up onto the hospital-style bed, staring straight ahead at her reflection… and slowly, subtly at first, her body began to change. Though she couldn’t feel it, the serum was working its way through her body, starting its work, figuratively baking her from the inside. She could feel a growing heat in her body, a pleasant and calming warmth, the sensation of being bundled in blankets.

    “Oh! I think it’s starting!” Taylor yelped slightly with glee and apprehension, placing her hand flat on her belly, feeling the growing heat. “It’s weird, it feels so warm and cosy.” She grinned, shivering a little as the warmth flowed through her body, her whole body heating up. It was then Taylor noticed her belly was starting to rise, swelling up, squashing under her fingers.

    She could feel her flesh tingling, growing spongier and fluffier, pushing outwards as pockets of air started to form between her changing cells. Taylor watched as her skin started to change colour, a rich tan spreading out from her belly, shifting to a strangely delicious looking golden brown, realisation starting to dawn on her.

    “Am… am I turning into dough?” She asked, incredulous, holding up a set of puffy fingers to her face, watching as the texture of her skin changed from smooth skin to rough dough, glittering with caramelised sugar. She breathed in, inhaling the familiar aroma of freshly baked dough. As good as she smelled, it seemed quite different when she was the food. As more of her body changed, flesh turning to baked dough, she started to feel sluggish, her body so thick and heavy, her breathing slowing down.

    “Erm, not just dough… but yes,” Dr Grey replied, pausing a moment from scribbling notes down on his clipboard, watching Taylor’s rising body pushing out into her clothes, her golden-brown skin suiting her blonde hair so well.

    “What do you mean, not just dough…?” Taylor asked, still so uncertain how she felt about her changing body. Gazing down over her swelling front, she tugged and pulled at her tank top, trying desperately to get her breasts settled. Looking back at herself in the mirror, seeing them bulging out of her clothes, looking so much like glazed buns… or doughnuts. Her skin started to turn a deeper brown, beads of chocolate frosting creeping out from under the edges of her hacked, shining brightly under the laboratory’s lights. Spreading across her skin, the frosting gathered in a thickening layer, cool and chilling against the warmth of her baked body.

    Confused at first, Taylor reached down, dragging a dough-finger through her chocolate coating, drawing it back. She could feel the weight of it sinking into her skin, weighing her fingers down, sticking her fingers together. Tentatively, she stuck the finger in her mouth, licking the chocolate off, tasting both it and her dough body, realising just how delicious she was becoming. She quickly pulled her finger back out, in case she was tempted to bite down on it, realising she could still taste the dough as the changes spread through her mouth.

    “I… I’m becoming a doughnut, aren’t I? Or, at least, a human doughnut?” Taylor asked, piecing things together, still so stunned her body was turning into food - though at least she was becoming her favourite food. “I’m not going to be like this forever, am I?” She asked, a hint of fear in her voice.

    “Oh, no, it should wear off after a week or so,” Dr Grey set his clipboard back down, focusing on reassuring Taylor, “and any part of you that’s eaten will grow back before then, too…”

    Taylor gulped in response, not even thinking about the idea of being eaten, though she had to admit the temptation was growing, her new body feeling and smelling and tasting so wonderful. She closed her eyes, trying to calm herself a little, worried she was getting a little too into the changes.

    “Wait… if I’m becoming a doughnut, does that mean I’ll have a cream fil-AH!” She gasped, interrupted by the sudden rush of custard surging inside her body, filling out her stomach, pushing out against her doughy skin. Her belly swelled, fuller and rounder, sagging slightly with the weight of the custard, pressing down against her thighs.

    “Oh… oh… that feels strangely good, actually…” She reached down, gently rubbing a hand against her bulging belly, running underneath it, hefting its weight. Stretched out, her changed body seemed so much more sensitive with the quivering weight of the cream filling behind with. “I guess I could get used to this…”

    Taylor lifted herself off the bed, dropping her heavier body down to the ground. A shockwave of pleasure rolled through her body as the bulk of the cream filling inside her shifted, setting her sides quivering. Before she had a chance to settle down, the pressure building inside hew grew again, another rush of cream filling her out. Her sides swelled out, expanding flesh pressing and straining against her pants, spilling out over the top of them.

    Letting out a contented sigh, Taylor ran her hands down her sides, tracing the contours of her growing body, her thighs beginning to swell out inside her clothes, fabric stretching tight against them. Each surge of custard felt better than the last, testing the limits of Taylor’s body as much as her clothes, her dough skin growing almost as fast as the custard stretched it out. Biting her lip, digging into her delicious body, Taylor almost lost herself in the sensations.

    “Ms Kingston… Taylor, are you alright?” Dr Grey leapt up from the cabinet, alarmed to see her swelling so rapidly, her body becoming rounder and rounder with each passing moment, the weight of her becoming almost too much for her expanding legs to bear.

    “I’m… okay…” Taylor gasped between swells, her arms lifted out to the sides by her ever-expanding torso, pushing outwards to doughnut-like proportions.  Everywhere her body bulged and grew, each inch of her crammed full of the delicious feeling, her body becoming impossibly sensitive as it stretched out. Her breasts grew heavy on her chest, thick with the rich filling, flattening out on top of her bulging belly, only just contained by her clothes.

    Soon, Taylor’s gasps her turned to moans of pleasure, her mind almost overwhelmed by the sensations of her changing body. She could barely comprehend just how heavy and bulky she was becoming, her legs pushed out sideways by the latest surge of cream, sitting herself down on her inflated rear, the straining fabric of her pants barely holding together, cutting into her waist. Only her head seemed unchanged, nestled on top of her body behind the rising form of her breasts, a look of pure bliss across her face. So overwhelmed by the changes, Taylor barely registered Dr Grey was even there, let alone trying to get her attention.

    The pressure continued to build inside her, the seemingly endless expansion of cream inside her finally more than her body could handle. The tension finally released as her belly button gave way, cream spilling out of her body, trickling down her front.

    “It feels… so… gooooood….” Taylor gasped, dazed and content, the feeling of release washing over her.

    “Heh… glad you enjoyed it.” Dr Grey replied, a relieved smile across his face, making a mental note to dial down the formula a bit. Returning to his clipboard, he made a few final notes before turning back to Taylor. “Alright, let’s get you out to the recovery ar-” Dr Grey sighed, pressing his hand against his face.

    “... we’re going to need a bigger door."
