It’s weird being a twin. Having someone look exactly like you, sound like you, walk like you, even think like you! That was me and my twin sister Karis. On the 5th January 2000, my mother gave birth to us, calling me Sasha and my sister Karis. We were inseparable growing, not only were we twin sisters we were also best friends! 


That was until high school though, as we got older and puberty kicked in things started to change between us. I started gaining a little weight and Karis stayed slim, I couldn’t get my head around it, we ate the same amount of food, we both worked out at the same time, it seemed like my metabolism was a lot slower than hers!


By the time we finished school, we were no longer best friends, in fact we barely spoke, when we did it would turn into an argument! We are both only 5’4 tall, both have fiery red curly hair, both have a little splattering of freckles, the only difference is she weighs 140 pound and me? I’m closer to 250!


Karis had an athletic look about her, flat toned stomach, tapered waist, round and firm ass and of course a perky pair of breasts that she uses to her advantage by wearing low cut tops and sports bras! I was the complete opposite, it seemed the heavier I got the hungrier I got. My weight seemed to accumulate in my belly mostly, it hung over the waistband of my underwear and jiggled uncontrollably at the slightest of movements! My boobs were also bigger than Karis’s but they wasn’t perky, more like udders that sagged down either side of my gut! 


The weight gain caused my popularity to decline rapidly. I ended up hanging out with the so called ‘nerds’ and ‘geeks’ which to be fair turned out to be a blessing because most of them were incredibly smart and helped me get good grades. Karis was one of the most popular girls in school, everyone worshiped the ground she walked on. She seemingly had a different boyfriend every other month! I hadn’t even kissed anyone.


At 18 my good grades paid off, I managed to get an accounting apprenticeship which I enjoyed extremely, that’s where I met my boyfriend Joe. He was a bit of a geek I suppose but he was funny, good looking in his own way and treated me perfectly! He certainly knew how to treat and pleasure a fuller figured woman! 


Karis was still unemployed at 18 but to be fair she was trying to become a personal trainer, she had quite a big following on Instagram which she was going to use to promote her career but until then she was more than happy to sponge off our rich parents.


It was our 19th birthday that things changed. We all gathered around the table in my grandmas large house, I was probably close to 270 at this point, I guess that’s what being comfortable in a relationship does! 


Me, Karis, Joe, mom, dad and grandma all sat around the large dining table making general chitchat whilst enjoying the rich hearty food my grandma had made for everyone. After dinner my grandma bought out a massive homemade triple chocolate cake with 38 candles on it and sat it on the table in between me and Karis.


‘Jheeze Sash, stop drooling!’ Karis laughed mocking me as usual.


‘Karis, for once in your life, shut up’ I snapped.


‘How about for once in your life, stop eating!’ She hissed back venomously


‘To far Karis! You don’t know what it’s like to struggle with your weight!’


‘No, you’re right, I don’t know what it’s like to struggle with my weight because I has something call SELF CONTROL, you should try getting some!’


‘Girls! Girls! Stop!’ My grandma interrupted ‘when are you to going to start getting along again?’ She followed up.


‘Never’ Karis said under her breath, just loud enough for me to hear.


‘Both of you make a wish and blow out your candles’ grandma insisted.


After watching Karis half heartedly blow a few candles out, I closed my eyes and made a wish, I wished Karis would be become gluttonous and insatiable. I blew out the remaining candles and smiled as my grandma cut us an equally sized slice. Little did I know my wish was about to come true…



Throughout the week I watched as Karis seemingly turned insane, she couldn’t sit still, she couldn’t hold a conversation, she paced around the house all day and she was quite literally pulling her hair out! I couldn’t quite put my finger on what was wrong with her. My mother asked Karis but she quickly dismissed her. 


About a week after our 19th birthday, I was startled awake by a noise coming from downstairs. I slipped my dressing gown and slippers on and quietly crept down the staircase, trying my best to avoid the steps that I knew creaked.


It was Karis, standing in her pyjamas, in front of the fridge, mindlessly cramming food into her mouth, moaning orgasmically as the calories filled her stomach! I snuck back upstairs and evilly laughed to myself. My wish had actually come true, Karis was going to finally know what it feels like to be ravenous all the time!


I smugly watched as Karis slowly spiralled out of control, he gym clothes got tighter and tighter, until eventually she had to buy bigger sizes, although she skipped the gym clothes because she wasn’t going to the gym anymore, he sudden weight gain caused her to become more of a recluse, she simple just sat around the house, wearing large baggy clothes, telling herself she’ll go to the gym tomorrow as she stuffed more junk food into her mouth! 


Of course she never did make it to the gym, in fact after 4 months of not going she cancelled her membership. Plus she lost thousands of Instagram followers because she hadn’t posted anything for 6 months. She was literally turning into a fat lazy pig who did nothing but spend our parents money on food to stuff her face with!


Before I knew it, it was our 20th birthday, it had been an entire year, I wasn’t sure how long my wish was going to last, so I planned on making another, just encase!


‘Karis! Hurry up your cake is ready!’ My grandma shouted as we were all once again sitting around the big table staring at another large triple chocolate cake, this time with 40 candle burning away on top.


‘I’m coming!’ Karis huffed as she walked through the door. She looked huge but because she always wore baggy sweatpants and large hoodies it was hard to tell exactly how big she was. She sat down an instantly blew a few candles out, eager to tuck into the cake. I closed my eyes once again and wished that Karis would become even more insatiable, even more lazy and have no dignity either. I blew out the candles and as my grandma began cutting a slice Karis, she stopped her and asked grandma to cut it bigger.


That night I was awoken again, it was 12:05am. I once again quietly crept down the stairs and to my shock I found Karis in the living room. She was barely dressed, her pyjama shorts where tightly digging into her pale flabby cellulite infested thighs, her tank top barley covered her braless breasts allowing her belly to surge out from underneath and hang over the waistband of her shorts. She was quite obviously fatter than I was and I was over 280 pounds! She was holding a plate in her left hand and cramming handfuls of our remaining birthday cake into her mouth with her right hand, her face was smeared with chocolate frosting and crumbs stained the front of her tank top. He didn’t care though, she didn’t even stop eating when I walked into the room.


‘Karis? What are you doing?’ I asked with shock as I walked closer to my once athletic twin.


‘UUUUURRRRRPPPPPP! So..mph..fucking..mph..hungry!’ Karis exclaimed after belching loudly and continuing to stuff her face.


‘What’s the matter Karis? No willpower?’ I cackled evilly 


‘No! I don’t UURRPP! I’m sorry..mph..I didn’t understand! So please..mph..get me more food!’ Karis begged as she polished off the last of our birthday cake.


I happily agreed to get her more, after all this was her punishment for treating me badly for years! Everyday I’d come home from work to find Karis exactly where I left here, on the sofa, barley dressed, still stuffing herself with junk food. She was ballooning rapidly!


As you probably know, corona virus fucked the world completely. We knew it was coming but it was still a shock being put into lockdown. I was fortunate enough that I could still work from home, all I needed was a laptop. It was quite nice actually, i managed to get most of my work done in just a couple of hour in the morning, so the rest of the day I could focus on bringing my morbidly obese twin sister more food!


At the beginning of lockdown she was eating something homemade for breakfast and lunch and a takeout for dinner, plus snacks in between her meals. But as her body grew this wasn’t satisfying enough for her, she needed more.


By September 2020, she was eating breakfast, snacks, takeout for lunch, more snacks, takeout for dinner, dessert and finally more snacks. She was absolutely huge, l somehow managed to convinced her to unstick her fat ass from the sofa to weigh herself, she was reluctant but I bribed her with the promise of delicious food.


545 pound flashed back at her. I stepped back with disbelief, how could my twin sister be so heavy? Could she have really gained over 400 pound in less than 2 years? That’s when I noticed how big she actually was, like me her belly held most of her weight, it was big round and flabby, it hung low, past her vagina and down to her knees! Her vest didn’t even attempt to cover her belly, she simply let it hang freely and jiggle with every movement she made! Her boobs were now like udders, each one sat either sat of her belly and hung out from underneath her vest to where her hips used to be, sometimes, when she’s not cramming food into her mouth she suddenly remembers where she is and tucks her boobs back into her vest, it doesn’t last long though, the vigorous speed of her eating soon causes them to flop back out. Her ass is not longer round a firm, oh no, I guess after 21 months of doing nothing but sitting and eating, it’s now flat and wide, each cheek is plastered in cellulite that spreads all down her ass and thighs. Every slowly cumbersome step she takes causes her ass to sway uncontrollably. I just wish all of her ex lovers could see her now, 545 pounds of pure fat, relentlessly eating, sweating constantly and stinking up the room with her flatulence!



‘Sasha…’ Karis huffed as she stepped off the scale.


‘Yes Karis?’ 


‘What’s for..huff..breakfast?’


‘Takeout?’ I smiled as I pulled out my phone to order her more junk.


From that day on she ate takeout for breakfast, lunch and dinner, obviously she snacked in between as well. We couldn’t celebrate our 21st birthday round my grandmas like we traditionally did, Karis was just to fat. Over the Christmas holidays she ate more than I thought was humanly possible, which led to her breaking the sofa, her weight completely shattered it. Karis ended up vacating to her bed, she ate Christmas dinner in there all by herself, well unless the 2 whole turkeys she consumed count as company? 


So by the time January the 5th rolled around, Karis still hadn’t left her bed since December 20th. 16 days of constant binging. At that point she was eating 4 takeouts on top of her constant supply of snacks. Grandma had to bake her an entire separate cake, bigger than our normal one, just for Karis! She ate it singlehandedly in one sitting. I made another wish, I wished for her appetite to double. 


*DINGDONG**DINGDONG*


Ahh that must be Karis’s pizza’s, her sixth takeout of the day and it’s only 3pm. 


‘Don’t you move a muscle! I’ll get it’ I say sarcastically with a chuckle.


‘Very..UURRPP…funny!’ Karis says with an eye roll as she grabs another piece of fried chicken from her fourth and final bucket of KFC.


‘Oopff!’ I exclaim getting off the sofa. Don’t think just because the focus of this story is Karis’s gain that I’ve been lucky enough to resist the tantalising tastes of all that hot greasy junk food. Oh no, after all it was my appetite that made me make my first wish! 


It was lockdown that sealed my fate, me and my boyfriend Joe split up shortly after it was implemented. He didn’t understand why I wanted to lockdown at home with my sister instead of with him. Plus I was pretty darn close to 300 pound then, I think I was getting a little to heavy for him! I also quit my job, it was just to difficult looking after Karis, working and eating. Now me and Karis are both unemployed, living off our parents hard earned money. They don’t seem to mind though as long as we’re happy and getting along. 


It’s crazy how much we’ve bonded over food and television, to be fair that is all we’re really capable of doing, Karis lays in her Alaskan king sized bed and I sit in the 2 seater sofa next to her. Although the rate I’m gaining, I’ll need my own king size bed soon!


I’m currently weighing 605 pound, everything is getting difficult, even now as I’m carrying the 5 large pizzas back to Karis’s bedroom I can feel my entire body jiggling and wobbling. I’ve adopted Karis’s signature look, tight shirts and vest tops that only just cover my huge melon sized tits, so with every cumbersome step I take my belly slaps against my bare rippling thighs with a distinctive clapping sound.


‘Pizza…huff…time!’ I pant walking into the bedroom.


The only good thing about my weight gain is I’ll always look slimmer next to Karis! It’s our 22nd birthday tomorrow, meaning Karis hasn’t left her bed for 380 days. As you can imagine she’s impossibly fat. I managed to find a scale that fits underneath her mattress so I can track her weight from the app on my phone, she’s currently weighing 2068 pounds.


It’s crazy to think that under all that flab is my once horrible, skinny little sister. Now look at her, so big that she make the Alaskan king mattress look small! Although the mattress is 9 feet wide her ass and thigh fat over flow it either side by a good foot! Although that is fairly impressive, it’s her belly that takes the crown. It surges forward in 2 large flat globes of fat past the end of the mattress and overhangs the end of the bed by at least 2 and a half feet! She no longer has the decency to cover her breasts anymore either, although it’s hard to tell that they’re breast and not just another belly roll, they flow outwards across her thigh fat and stop about half a foot from the edge of where the mattress should be! 


Although she’s over a ton, she can still use her arms, it’s the only thing that have kept relatively mobile. My dad set up a pulley system running over the top of her ever growing body, so food can be easily transferred across the blubbery mound of fat she’s calls a belly without having to physically climb over her. 


Although Karis had only just finished her fourth bucket of KFC, she was already tucking into a platter of candy bars. Karis doesn’t reply to me, I don’t expect her to, I simply load 4 out of the 5 pizzas onto a tray and crank the handle making the pulley system drag the pizzas to their savage fate. Karis instantly opens the first box and crams 2 slices into her mouth making piggish gluttonous noises as she does so.


I take a seat next to her and open my pizza box, taking a deep breath of the melted cheese and tomato smell, I smile contently as I pick a slice up and, just like Karis, cram the entire thing into my mouth greedily. I can’t help but notice how tight the sofa feels against my ass. I wonder if another Alaskan king will fit in this room?
