Feed Me

Carla was never the same after the experiment. She never told me exactly what happened, and frankly I was too scared to ask, but there was just something…about her. Something different. At times I wasn't sure if it was something I loved or something I feared, but it was there. It was in her eyes. A kind of hunger that I should have noticed sooner. But I was blinded to who she really was. To who I really was, if I'm being fully honest.

When she emerged from the machine, smoke pouring out, a power surge having blown all the lights, I feared the worst. But she seemed fine. The transmutation was a success, her body had proved it was able to be affected by the process, and she could now…change. She could alter her physical shape, reconstituting her body in moments with a strange, slightly slimy sound that I also grew to love and fear.

But as she emerged, she just looked like herself. A little limp, perhaps, slightly sagging, like she was just getting her head around how to control her new abilities, but definitely herself.

She hugged me, still wearing the special silver nanomesh suit that was designed to contain her form in case of disaster. And when her hands touched me, there was a kind of sticking, just for a moment. She smiled at me, and I hugged her, and told her everything was going to be ok.

I truly believed it.

When we were home that night, she ate like a horse. I'd never seen her so hungry. I knew she hadn't eaten before the experiment, that had been a precaution, to keep her body as free from fluids and solids as possible in case of contamination, so that made sense. But to see her cramming food into her mouth, it was like she hadn't eaten for a week.

"Are you ok, dear?" I asked, eating a stick of celery.

She nodded, stuffing another fistful of fries into her mouth. Her stomach blobbed outwards, like it was a bag being filled. We'd discussed side-effects, and so far, there didn't really seem to be any. She'd stepped out of the suit after we'd done all the checks and scans, and her body seemed to be holding together fine. If anything she looked better than before, like she'd been tightened up, everything tweaked, slightly.

As we were sitting there over dinner, she looked up at me.

"I've seen you looking at me differently." She smiled, wiping her mouth with a napkin.

"Oh?" I hadn't realized I was doing that, but Carla was very observant.

"You like my new body, don't you." It wasn't a question.

"I, uh, I haven't noticed a big difference, but in general yeah, you look good."

She stood up now, her belly full from all the food. It bulged out in front of her, like she was a month or two pregnant.

"What do you think of this?" She said, and then sucked her belly in. I waited for her to breathe out and for it to return to its full size, but it didn't.

"Did you…what did you do?" I asked, my mouth open.

"What do you think, doctor? I…redistributed."

She smiled wide, and then turned to the side, bending over slightly to show her ass in her sweat pants. She'd always had a good ass. As I watched, it seemed to plump out slightly, her behind swelling and growing to fill out the pants. They rose up slightly as her butt filled out, and before long she had what looked like a considerably larger booty. Her pants were tight over it. She looked good.

"You can…you managed that so quickly. That's…that's incredible\!"

She giggled, slapping her ass. It wobbled and shook, and I found myself growing very hard indeed. "Mmm, looks like you're growing too. Shame it's my turn again."

She walked to the freezer, and I found myself hypnotized by her big new ass, shaking from side to side, filling out her pants as she strode across the room with powerful, thick legs. She grabbed a carton of ice cream and practically poured it into her mouth. She swallowed it down like a goose being force fed grain, her throat opening to accommodate it.

"Hungry work." She explained. And then she turned to me, and closed her eyes for a moment. And her breasts began to grow.

I can't describe to you how it felt the first time I witnessed this. All through our scientific research together, long before we became romantic partners, we had both been obsessed with the idea of genetic manipulation, of bodies that could alter themselves to fit certain parameters. And there had been many reasons I was fascinated with that, with the potential it had, with the applications in life, for health reasons, for medical research, for so many things.

But it was only in this moment that I realized what I really wanted. I wanted someone who could change their body to my perfect fantasy. I wanted all the other stuff too, that would never go away. But there had been a drive in the back of my mind, and here it was, forced out into the open the first time she leaned over and grew her breasts. And it split my brain in two, and a new idea fluttered out, fragile but powerful all at once.

Grow. It said. Grow and grow and grow.

Carla's eyes remained closed, and she bit her lower lip. And her small, pert breasts began to swell outwards. It was slow and deliberate, but very sensual and incredibly arousing to me. Her small breasts gradually plumped up, and as I saw them expanding I found myself wondering what that must feel like, to witness yourself blowing up in front of your very eyes. I was fascinated and a little jealous all at once. Carla's breasts continued to expand, swelling up to substantial D-cups before stopping. Her once small boobs were now decently sized melons, adding significant curve to her body, giving her a much more hourglass figure. Her bra looked like it was going to pop off any moment, and her top was gloriously tight, showing off her new boobs and just how large they were.

"Uhhhhh." She finished, slumping into a chair and staring up at me like she'd just had a massive orgasm.

Her lips were plump, her ass was bloated and her breasts had grown – she looked incredible, and like everything I'd ever wanted. I sat down next to her and held as she breathed.

"A-are you ok?"

She nodded, her head resting in my neck. I could feel her breathing, her new, enlarged body in my arms.

"That was incredible." I whispered, my cock rock hard. Her hand drifted down to my throbbing erection, and gently brushed over it as it tented my pants. I could feel her smile.

"You like this, don't you?"

I nodded, clearly unable to hide my feelings.

"Want to go and take this body for a spin?"

"Are you sure you're able to?" I asked, holding her and looking into her eyes. She looked a little giddy, a little punch-drunk, but her eyes were clear and determined. She had gone through hell today, she had taken her body to the brink, but she had survived, she had turned herself into something more than human, and she was very much entitled to any reward she wanted.

I took her hand, still a little sticky and loose, and we walked to the bedroom. As we stepped inside the dark room I felt her hands on me, and she wrapped her arms around me from behind. I felt her breasts pushing into me, and my boner intensified. They felt so big, bulging against me, and yet they were completely real and all hers.

She reached down to my cock, and I hastily removed my pants and underwear to have my generous dick thrusting out in front of me. Her hand moved down, still a little sticky (or was it sweaty) and she began to jerk my cock back and forth. It felt incredible, and the large breasts pressing into my back were sending me wild.

"You want me bigger, don't you"? She purred, reading my mind in a way that was so accurate it was almost unsettling.

I nodded, my throat dry, and I heard her breathe in deep and concentrate once more, and then I felt the glorious sensation of her twin mounds pushing into my back, hard and firm and powerful, slowly swelling bigger as she jerked my cock back and forth. The imagined visual of her tits growing larger along with the physical sensation of them pressing into my back was almost uncontrollably arousing, and I felt myself growing so hard I thought I was going to come there and then.

"Uhhhh." Carla moaned again, as her breasts grew larger again. Their huge fleshy masses bulged into my back, and her hand whipped across my throbbing cock faster and faster, and before I knew it my mind exploded, my balls pulsed and I came hard and fast and again and again until I felt utterly drained.

"Mmmm, that was nice." Carla smiled, releasing me as I fell to my knees and lay on my back on the floor, looking up and smiling a stupid smile.

"It sure was." I grinned, feeling like my soul had been given a spring clean. It was one of those orgasms that completely resets your brain, and makes everything feel easier and lighter.

Carla stepped over me to the cum that I'd blasted onto the bed, and began collecting it with her finger, before dipping it into her mouth and eating it.

"Lots of nutrients here, not gonna waste it." She said, her breasts large and full and incredibly pert on her chest.

"Works for me." I smiled, getting up off the floor and giving her a kiss. I went to the bathroom to clean myself up.

"Where do you think you're going?" I turned to see my now busty beauty of a girlfriend sitting on the bed, her legs spread.

"My turn."

"Quite right." I smiled, placing my head between her legs and going to town.

"Uhhhh." She moaned, and in that moment I genuinely wasn't sure if she was getting pleasure from my tongue or if she was growing again. Or both.

She came hard and fast, and then we were both in shower, washing ourselves clean and making out furiously, running our hands over each other bodies, both of us focusing on Carla's fat new tits and big ass. We were obsessed by her growth, not just the scientific potential but just how it could revolutionize our sex lives, and the thought of what the future held was incredibly intoxicating.

We both fell onto the bed shortly after and drifted off to sleep. I dreamed of Carla, but she was a giant now, with preposterously large boobs, a huge ass and then I realized her body was huge, she was a giant, walking through the city, crushing everyone underfoot, and then she took me, picked me up off the ground, raised me to her enormous mouth, which was like a massive open cave, and dropped me inside.

I woke with a start. The room was dark. Carla wasn't there.

I got up and moved to the living room to see her passed out on the sofa, an open laptop in front of her. I grew alarmed. She was terribly thin, her body skin and bone, all except her breasts which were, if anything, even larger than last night. They sprouted out from her body and looked even larger due to her skinny form. I'm ashamed to say my immediate reaction was to get a throbbing erection, but I pushed that aside and squatted down next to her. I looked at the laptop screen. On it were women with huge tits, either giant breasted porn stars or one with huge fake breasts. Clearly she'd been trying to imitate them.

Carla stirred, her eyes barely opening.

"So hungry…" She whispered, her head lolling to the side.

"You sit tight. I'll make you your favorite." I said, rushing to the kitchen and grabbing whatever we had. I threw bacon and eggs in the skillet, tossing in bread and sausages and beans and anything else we had. Before long I had a big pile of carby, protein-y food. I hoped it would be enough.

She started to stir as the bacon scent moved through the apartment, and before long some color had returned to her face as I prepared a huge plate of food.

"Here you go, eat up." I said, placing the plate in front of her. Her breasts bulged out crazily from her slim form, almost getting in the way of her eating. How big had she grown? She looked like an E or F-cup, maybe even bigger. She looked incredible, but I also needed her safe and healthy. As my girlfriend, first and foremost, but as a scientific marvel too. I fed her up, giving her everything we had, emptying the fridge and some of the freezer in an attempt to fill the void inside her. She just kept eating, filling herself up bigger and bigger, until her stomach bulged like a balloon.

Then she sat back, belched hugely, and patted her huge stomach. Gradually the rest of her body returned to its normal size, like a bicycle tyre being pumped back up. Her breasts had even deflated a little, she was so hungry, but now they were back, full and firm and incredibly large, and she looked completely back to normal, except for the fact that she had a huge pair of tits where her normally small breasts were.

"How are you feeling?" I asked, my eyes full of concern.

"How do I look?" She replied, a twinkle in her eyes.

Her shirt was drawn tight over her massive breasts, and I had to be honest, the way it was stretching over them turned me the fuck on.

"Honestly?" I said. "You look fucking sexy and I want to do you right here."

"Mmmm, that's what I like to hear." She smiled, and lay back on the sofa, her breasts arching up and threatening to obscure her face a little, they were so large. I loved watching her enjoy her tits, luxuriate in how big she was getting, and I loved how her big ass spread out beneath her, her thick thighs promising treats untold if I simply leaned in and took them.

"Come and fuck me then. I can't promise I won't grow a bit bigger."

I tore my clothes off, my penis pulsing with pleasure as I slowly straddled Carla and lowered my big dick inside her.

"Mmm, that feels so good." She moaned, and her eyes met mine, as I slowly began fucking her.

"I think we're going to get some grat results out of this experiment." She smiled, her hands kneading her huge, soft tits, burying her fingers into her giant, plush boobs.

"I think I'm inclined to agree." I smiled, placing my hands over hers, feeling her bulk beneath my fingers, my cock twitching with pleasure.

"Now how about I get a little bigger?" She said, her eyes fixing on mine, a devastating twinkle sparking in them.

"I'd like that very much." I said.

And Carla started to grow

Carla's body engorged as I fucked her, and I could feel every inch of me tingle with pleasure as I slowly watched her expand. I flipped her over so that I was fucking her from behind, her kneeling on all fours on the couch, me kneeling behind with my big cock inside her. I was overcome with lust, no longer concerned about the experiment, or recording information, or the fact that her skin was slightly sticky – none of that mattered to me, as I reached down and felt the huge, squishy plushness of her large breasts hanging down from her slim form.

All the food she'd ingested was now in her system, swimming through her veins as she redistributed it to where she wanted it to go. And I as slowly side my cock into her tight cunt, I grabbed the huge softness of her right breast, and felt a pulse of joy inside me as it started to slowly grow into my hand.

"Uhhhhh." She moaned, and I felt her already huge boob push gently but urgently into my fingers. It was like it was trying to escape, trying to push me away, and every inch that it grew bigger, I grew more insane with lust at my bulging, busty girlfriend. The fact that she was so turned on by the growth only made it more appealing.

"How big do you want me?" She asked, as I leaned down and bit the back of her neck, my cock buried deep inside me.

"How big can you get?" I replied, with a laugh.

"Oh you have no idea."

Little did I know what I had unleashed in that moment.

Carla's ass, already considerably engorged, bulged outwards into me, and I could feel her fat cheeks pushing into my thighs. I loved how soft and wobbly she was, but there was a tightness there, a solidity to both her ass and tits that made them feel substantial and real, despite their increasingly ridiculous size.

"Mmm, you feel so good." She purred, biting her lower lip as I pushed my cock further inside her dripping pussy. Her breasts were getting so big now they were starting to spread out wider than her torso, and I found myself imagining what they would like stuffed into a push-up bra, giant and lifted and bulbous and perfectly sexy. I found myself almost drooling at the thought.

I pumped her harder and I heard her huge boobs start to slap into each other, and then I knew I was going to come.

"You're too big." I moaned, but there was no complain in that voice. It was statement, and it was all pleasure.

"And I'm only going to get bigger. I'm going to push the limits of what is humanly possible." Carla grunted, as my hands ran over her large, full breasts, and I began to come. I could feel my balls throbbing and preparing to blast off, and Carla was moaning and crying with pleasure, swelling slowly larger all the time. Her tits and ass were so big, but as I came I could feel them swelling even bigger, and that pushed me over the edge into an orgasm so powerful I could barely think straight. I cried out like an animal and came again and again inside Carla. She did the same, grinding her ass and pussy against me as her body ballooned, and before long we were lying on each other, panting and gasping, covered in sweat.

At least I thought it was sweat.

We pulled away with a stickiness that should have concerned me, and then I was lying on the floor, Carla on the sofa, gasping for air, giggling like teenagers.

"That was fucking great."

Carla's stomach rumbled.

We both laughed.

"Hungry again already?" I grinned.

She looked down at me, a fierce grin on her face.

Was that fear behind her eyes?

"You know it." She smiled. I got up, went to clean myself off, but Carla beckoned me over. She pulled my cock into her mouth and I felt her tongue running all over my thick length, sucking all the cum off and swallowing it greedily.

I looked down at her, almost ready to go again, and I noticed just how huge she had become. Her tits jutted out like huge round melons, full and pert and gorgeous, and I couldn't even imagine what bra size she must be now. Gs, Hs perhaps. Incredible. She looked so hot I didn't want to leave. But then that gurgle again, and a slight look of desperation on her face, and I thought I'd better get going.

\\

I returned from the store laden with food, and Carla practically attacked me. She tore the bags open, grabbing anything that was ready to eat and shoving it into her mouth.

"So hungry." She muttered, in between stuffing her face with food. Her body looked slightly deflated when I returned, but nowhere near as bad as before. Now as she stuffed it, it started to puff back up, and then get even larger. She was swelling up. Had she been trying to grow more while I had been away? She was thickening everywhere, her thighs getting larger, her butt and hips getting even more substantial, her boobs huge and swollen, even a little pot belly appearing for a short while, before it was sucked back in and the nutrients were distributed elsewhere.

"I've always wanted to be a curvy girl." Carla said, taking a can of squirty cream and emptying the entire thing into her mouth. "And now look at me." She grinned, her body expanding outwards in all directions.

"You should be careful, though." I said, unloading the food into the fridge and freezer, preparing a nice big carby lunch of pasta and bread.

"Careful?" She laughed, grabbing a huge bag of chips and tearing it open, pouring them into her mouth. "I just need to keep the furnace running and I can be whatever I want."

"I know, and you look great." I said, leaning behind her and running my hands over her growing belly. I looked over her shoulder and stared down at the incredible cleavage that was thrusting out from her thickening figure, and almost came there and then. There was so much boob on display it was insane. She was getting unbelievably thicc, in all the ways.

"Oh yeah? How about now? Uhhhhhh." Carla closed her eyes, bit her lip, grabbed my hands and placed them over her huge tits. Her shirt was already pulled so tight over them, but now it was stretching beyond capacity, the words on it greying out and starting to become warped and illegible.

The feeling of holding her giant breasts as they swelled bigger was almost too much to bear. It felt so incredible to feel her tits slowly getting larger in my hands, that I had to have her. Then I felt her ass swelling into my throbbing, pulsating boner and it was too much. I tipped me over the edge.

"I have to fuck you right now." I growled, and Carla giggled with glee as I pushed her against the fridge and pulled down her underwear.

That was easier said than done, as her ass had gotten so huge, her hips had gotten so wide and her thighs had gotten so thick that her previously normal underwear now resembled some kind of tiny thong, designed so show off as much of her huge ass as possible. The fact that her body had grown to dwarf her clothes this much was even more arousing, and I felt the wild animal inside start to take me over again. I grunted and growled and pulled at her panties to get them down. All the while I could her grabbing food from the counter and stuffing it into her waiting mouth, her jaws chomping down on candy, chocolate and, at one point, I heard the rustling of a huge bag of sugar that she just poured into her. The quantity of calories that she was ingesting was truly breath-taking, and a part of me (a tiny part) knew we should be recording these results for posterity, to know the kinds of energy levels it took to induce what kind of growth. But that would come later (I thought), for now, it was time to revel in the fruits of our discoveries, to have a little fun. I heard the most incredible eating and moaning sounds from above me.

By the time I had removed her struggling black, tiny looking panties from her monster thighs and ass, Carla had eaten everything within reach of her. I went to stand up, to brandish my trophy of the underwear removed, but my head bumped into something. Something huge and soft above me.

"Looking for someone?" Came the voice from above. It sounded muffled, but also a little deeper. And further away?

I moved my head backwards. And backwards. And backwards. And only then did I realize the scale of the impediment above me. The most enormous pair of breasts thrust out in the air above my head, and I realized that Carla had taken the time in which I was busy to become truly huge. Her breasts now bulged out in front of her like literal water balloons, so stuffed full and fit to burst it was like she was a sloshing, overfull water balloon herself. Her skin glistened stickily, and her top was so tight it looked like it was finally going to burst. She genuinely looked like she had shoved a couple of balloons down her shirt, but I knew it was all breast. I grew so hard looking at my pumped-up girlfriend I didn't know what to do.

"You're…so big." I managed, stumbling over my words as I stared at her magnificence.

"Notice anything else?" She purred, running her hands over her gigantic breasts, biting her lower lip and moaning.

"A-are you…taller?" Her head was closer to the top of the fridge than it had been before, her body was longer and more powerful, just bigger in every way. How was that even possible?

She nodded, her head high and proud, but looking tiny compared to the gigantic breasts that thrust out beneath it, taking up her entire chest.

"Fuck I want you so bad." I grunted, pulling myself into her monster chest, which yielded and bulged around me as I kissed Carla hard on the mouth, her immense tits bulging up to our chins as our chests connected.

"Mmmm." She moaned, and I knew it was her growth sound, I knew she was expanding for me as we made out, our hands running over each others' bodies as our lusts increased.

Her boobs swelled larger, pushing into me, almost pushing me away from her. I held her tight, so that her breasts instead bulged upwards and outwards, filling all the space between us.

"Uhhhh, it feels so good." She moaned, her breasts getting so large they were the size of her entire torso.

"Keep growing for me." I whispered, running my hands over her tits, and sliding my dick inside her as we fucked against the fridge. Every thrust of my dick sent her monster tits jiggling and shaking, and before long it was like they were always wobbling, so much mass that the slightest movement sent them vibrating. It was too much. I was going to come again. So hard, even though my cock was already raw from all the fucking.

"Yes\! Yessssss\!\!\!" Carla was crying, her arms above her head, pinned against the fridge by my hands as I ploughed her harder and harder. Her tits were so ridiculously huge now they almost buried my face, but I still continued, fucking her harder and faster as we were both brought closer to climax.

"Never stop fucking me\! I want to fuck and grow forever\!" She cried, her body responding to her demands by stretching even higher and wider, her entire form growing as I penetrated her again and again. Her ass spread out behind her across the fridge, her hourglass figure getting more and more pronounced as we both sent our bodies into overdrive.

Then I was starting to come, and so was she, our bodies climaxing in twin harmony as we cried out with pleasure and came, again and again. I filled her up with jizz, in quantities that I never thought was possible, as my body was rocked with orgasms again and again and again.

The climax that Carla had was off the scale. She was screaming with pleasure, her entire body shaking and rocking against the fridge as I buried myself inside her and blasted her with thick ropes of cum. I wondered if she'd made herself more sensitive as part of her changes, and that was what was sending her over the edge, or if it was simply the pure joyful lust of being able to change her figure into the bustiest, curviest woman alive that was what was doing it.

Either way, by the time we were done, we were slumped on the floor in a complete mess of bodies and sex and discharge, and we'd never been happier.

"That was the best sex of my life." I whispered.

"That was the best thing in my life." Carla replied.

"Wow, that's…that something." I smiled, rolling onto my back, my cock slowly deflating as it rested on my chest.

Carla did the same, but her tits were so huge they almost wobbled down onto her face, smothering her.

"Gonna take a while to get used to these." She grinned, wobbling them gently. The view from where she was lying must have been sensational. She would have been able to see nothing but breastflesh.

"I love them so much. I love you so much." I kissed Carla on the cheek, and slowly got up to a sitting position. Her stomach gurgled like a drain. Her body was so huge, she was almost as tall as me, and so thick and curvy. She was almost a different woman, but when I looked into her eyes I knew it was the same Carla, the one I'd loved for so long. Just pumped up and even more incredible.

Her eyes were wild and sparkling.

"I love you too. But I have to say. I'm really fucking hungry."

"That's ok, I'll cook us up something big. You've done a big workout."

"No, you don't understand." She reached up and touched me, her hand sticky, her eyes wide.

"I'm really hungry."

I looked down at her, her gigantic tits like cannon balls on her chest, weighing her down. If she'd tried to get up right now, I wasn't sure she'd be able to.

"Uh, I can make extra, if that's what you mean."

Carla's hand grew stickier, and I felt it connecting with mine in a strange way. Bonding, almost. I pulled my arm away and some of the skin was missing.

"Mmmmm." Carla moaned, biting her lip. The skin was on her hand – my skin, on her hand – for a second, and then it disappeared, absorbed into her.

"Oh damn that's good." Carla's breasts plumped out, growing about an inch in all directions. They wobbled like jello. They were incredible.

"I…um…I think I need more." Carla said, looking down almost shyly. It was a very strange moment.

"Are you saying what I think you're saying?" I managed, gasping a little.

"Yeah. I think to really kick this up a notch I'm gonna need…meat."

I looked over at the raw steaks on the counter, hoping they'd be enough. Deep down I knew they wouldn't be. But I had to try. I had to make her bigger. It was all either of us had ever wanted.

And she wanted to be so big.

Carla sat there, blood smeared around her mouth, after eating a huge plate of meat. Raw.

I could tell from the look on her face that it wasn't enough.

"Sorry, I'm just…so hungry."

Her body was so huge and pumped up, but even now I could see it slightly sagging at the edges, her arms starting to slim, her legs becoming narrower at the ankles.

But she kept all the fat and the size where she wanted it, and her breasts were now truly magnificent. I wondered if there was a bra size that would fit her, or if she would need custom mades from now on. She sat there on the floor, her huge tits thrusting out, taking up most of her top half, her thighs huge and thick, her ass massive, but her body was struggling. She had grown to be around 6 feet tall now, and that had put great demands on her. I could hear her body growling.

"So…what are you saying?" I asked, fear lacing my voice.

"I just…bring me Sasha, she'll know what to do."

Sasha was our prized research assistant, she'd helped us through some of the tricker aspects of the science on this job, and we both respected her hugely. It was a good idea. If anyone knew what to do about Carla's rapacious appetite, it was Sasha. I called her up, and before long there was a knock on the door.

Sasha, tall, brunette and very busty, strode into the apartment. We had dressed Carla up so as not to completely terrify Sasha, wiping the blood from her mouth from the raw meat and trying to find clothes that fit over her mammoth body. But her breasts were so huge now, that whatever clothes we tried to stretch over her enormous chest simply showed off how big she was. I tried to zip up a hoody to cover her more, but her tits were so gargantuan the zipper wouldn't lift up over them. It ended up at half mast, making her huge fat tits only look bigger. I sighed. It was impossible to cover up someone so huge. And the effort of doing so was only making me more horny.

I felt Carla's huge breasts bulge against me, and I turned to look at her, but even though I could tell she was turned on, the hunger was taking her over. She looked down at me, licked her lips and then pushed me away as Sasha arrived.

"Heyyyy." Carla smiled, opening her arms wide and grinning a toothy grin. I didn't like that one bit.

"What the fuck happened to you?" Sasha looked up at Carla, aghast. I suppose it must have been a shock, seeing her so changed in front of her eyes. So much bigger.

"The machine…it worked. I can transfer mass, change my shape."

Carla grinned from ear to ear, and closed her eyes, uttering an "unnnhhhhh". And her body stretched taller, her legs growing thicker and wider, her ass bulging out of her sweatpants, threatening to burst them, and her tits…they were getting so huge they almost reached down to her belly button. But at the same time they were so full and swollen and pert. I was so aroused I didn't know what do with myself. But part of me was worried – Carla was already looking so depleted, she needed to avoid pushing herself\! The rest of her body was getting so thin, but her tits and ass were bigger than ever.

"This is…this is incredible." Sasha breathed, walking forwards. I closed the door behind her.

"But the energy inputs this must require…how are you feeding this?"

"Funny you should ask." Carla said, taking a step towards Sasha. She was so heavy the apartment rattled a little. Her sweatpants were looking like they were going to burst open. Her breasts surged outwards from her, gently swelling even larger, like they were reaching out towards Sasha. The zipper from that struggling hoody slowly slipped down as the huge breasts above it swelled larger and grew heavier.

"I've tried everything, eaten so much food, and it's still not enough."

"I bet." Sasha was looking at her phone now, running numbers on it. "To increase in this kind of way you must have had to ingest thousands upon thousands of calories."

"And that's not all. To get taller you…uhhhh…need much more than calories, you need meat, and fat and tendons and…bone."

Carla was in front of Sasha now, and at this point she was slightly taller than her. I watched as Carla's breasts gently pushed into Sasha, the zipper reaching the base of the hoody. Her tits were absolutely magnificent, so huge and plush and swollen.

"Can I…can I see them?" Sasha asked, her voice quavering a little. She had no idea of the danger she was in. Why would she?

"I thought you'd never ask." Purred Carla, licking her lips.

She reached around her humungous breasts, lifting their groaning bulk with one arm to unzip the hoody underneath. Then she removed the hoody before getting to work on the t-shirt, which was now so tightly stretched over Carla's giant jugs it looked like it was going to tear open.

"Wow. You're huge." Sasha breathed, as Carla pulled the shirt over the giant heft of her tits with extreme difficulty.

"Thank you." Carla smiled. Her mouth was huge and wet.

As soon as the magnificence of Carla's breasts were revealed, Sasha began to probe and prod them, gently but with wonder in her eyes.

"They're real, you've managed to simply…increase." She breathed, her wonder turning to a frown as her hand became a little stuck.

"Don't mind that, just a side-effect." Carla grinned. Sasha carried on massaging her immense tits, now both hands were on her and I knew this was the end.

"You may want to step outside, Mike." She said to me, and at this point I knew there was no turning back.

I couldn't move. I had to watch.

Sasha paid it no need. It was too late anyway.

Then suddenly Sasha was moving forwards, where she should not be able to move, and her body was just…falling into Carla's like where there should be two bodies there was suddenly just one, like Carla was made of water and Sasha was tumbling into her, but slowly, with some difficulty. And some screaming.

Thankfully her mouth was gone soon, then it was just muffling as Carla pulled at her back, pushing her inside her. The sounds were squelching and sticky and have never left my head.

But then Carla was done. There was no sign of Sasha, all of her personal items had been absorbed. And Carla's belly was enormous.

It was like she was pregnant with octuplets, and was about to burst. Her stomach bulged hugely, grotesquely from below her massive tits, her belly button pushed so far out it was like a light bulb. She let loose a belch that was more like a ship's horn, and patted her huge, protruding belly, with an arm that could only just reached the tip of her gigantic stomach. It echoed like a drum.

"Ohhhhh that was good. I'm so full."

Carla sat back on the couch, her belly so huge it pushed her tits up and into her face. She was covered, in that moment, by her immense protrusions. Her huge thick thighs were pushed as wide as she could, her legs spread to let her huge stomach swell down between her. It looked like she'd eaten a bean bag chair. I couldn't process it. She was beyond enormous.

But then, I heard a laugh from behind that huge mass of belly and breast, and then "uhhhhhh", and it slowly, so slowly, started to reduce. And Carla started to grow.

"Oh my god, I can't tell how good this feels." Carla was moaning, running her hands over her huge tits as they started to balloon bigger. They were already so large, I couldn't imagine how big they were going to get. Her gigantic belly began to slowly deflate, as all the biological material inside started getting hoovered up into Carla, to be distributed as she saw fit. Her thighs, already so thick, started to blob together, her ass expanding and inflating as she rose up on the sofa, bulging and ballooning all the while.

And her breasts, which were so incredibly large already, began to start to spread outwards across her body, getting bigger and heavier all the while, spreading over her huge stomach, which itself was continuing to shrink down so that all that goodness that was Sasha was now being put to expanding Carla's immense body.

Her boobs had swelled far beyond bra sizes around this point, so much larger than her head that her top half was largely breast, and still they grew, even as her stomach shrank back down. Her entire body was swelling, puffing up like someone had inserted a pump, and with each inch that she grew, she became more arousing to my growth-addled mind.

"Yes, keep growing." I muttered, and she obeyed, running her hands through her hair as her body increased in size. Her ass spread across the sofa, taking up more and more space as her legs were able to close due to the belly between them now being less enormous. But no sooner did they meet than they started to be pushed away again, as her thighs were so thick there was no space as all. She was ballooning out in all directions, and I loved every minute of it.

"Uhhhhh." She moaned, and started to rise up on the sofa. I realized at this point that she was growing taller too, and would soon be as tall as me. I longed for that, longed for her to eclipse that, to keep getting bigger, to grow and grow and grow until there was no more growing to be done.

Her tits were now the size of actual beach balls, her stomach reducing to look like she was heavily pregnant with twins. Her breasts swelled out like balloons, still growing larger, and I knew I had to act.

Perhaps you'll judge me harshly for allowing Sasha to be eaten, and for what I did next. I won't defend myself. I simply acted as my libido demanded.

"Ahhh, there you are." Carla purred, as I stood in front of her, her huge belly almost touching me. "Come here." She pulled me in, and her huge tits dwarfed my big dick. And then she began to tit fuck me while she grew, grasping my throbbing cock with her gigantic jugs, gripping it tighter and tighter as she ballooned into me, and before long I was gasping with pleasure as I knew I was going to come.

"I'm going to get so big for you. Would you like that?" She whispered, stretching higher and wider on the sofa, growing towards the ceiling. Her monster tits enveloped my cock and it was like there was nothing else, just these huge, swollen boobs gripping my cock with everything they had.

"Yes, more than anything." I muttered, and prepared to come. I was so turned on by this point I was barely functioning. She was getting so big it was hard to process. She was taller than me, with breasts like exercise balls. And still going.

"One last climax." She said, and then I was spurting cum all over her, blasting jizz wildly in a huge orgy of pleasure that seemed like it would never end.

And then I looked up at her, and her face was so far away. I was trapped between her growing breasts, which were now as large as bean bag chairs, and I felt a rumbling beneath me.

"Sorry, that's me. I'm feeling a bit…hungry."

I had known it would happen, deep down, before I even stepped near her. Part of me wanted this. There was no escape, and in some ways I didn't want it.

"Make me part of the experiment." I said, and leaned into the huge mass of flesh that was Carla's breasts.

"Join me." Were the last words I heard her say, as her skin became like liquid and I was falling through, tumbling into her and then everything went black.

\\

When I awoke I felt like I was going to burst. Like I was a balloon that could not take one more pump of air, or I would pop with a huge bang. I was a wobbling, shuddering mass, like jello, that was primed for an explosion. I scarcely dared move.

I looked down at a belly that rested on the floor. I couldn't even move my legs. I was almost resting on it.

So full.

Hi there

The voice was in my head. It was her voice. But also my voice.

Hi?

Are you ready?

Uh, where am I?

In me. In us.

Hi.

That's Sasha. She's not ready to talk yet.

I'm going to burst

WE are going to burst. But we're not. We just need to…uhhhhhh.

Uhhhhhhhhh

Uhhhhhh

We all started concentrating on what we wanted, which was to process the biggest meal of our lives, and then we started growing, I could see from my view of the apartment, from a very tall woman with breasts the size of a small bed, how small everything else was. And we grew. Taller and taller, our head moving towards the ceiling. And some of that terrible, beautiful fulness was alleviated, and suddenly I could think again, although my thoughts were mixed in with so many others, but even with all that noise there was a clarity of purpose:

Grow

Grow

Grow

We all thought it, and so we did. Our body expanded outwards, we sprouted up taller towards the ceiling, and our breasts bulged out into the apartment, threatening to smash the chair in front of us. The couch beneath us buckled under our huge thighs and ass, and our belly, which until now had been the biggest object in the room, started to slowly shrink down, our giant tits slowly overtaking it.

And I realized that we were one. One person, one enormous being of unity and expansion, that had designs on the world. All I really wanted, all we really wanted, was to stay fed, and to grow. Whatever had happened to Carla in that experiment now affected us all, and we all had a shared goal. We were going to get so very, very big. And as our body stretched towards the doors and the ceiling, as our body started to fill up the entire apartment, and bump into the corners of the room as we expanded, which felt so fucking good, by the way, one other thought popped into our head, a thought of pressing urgency that sounded like an alarm, even as our breasts became so huge they threatened to pull our body to the ground.

We are hungry.

We are so hungry.

And we must be fed.
