The fattest sister

Chapter 2 - sammy's truth

Listen to this chapter - just press play:
I’d just finished doing my make up when the doorbell rang. Sammy’s friends were coming over to have some drinks and stay the night. I got along with them pretty well, with a few of them being hot skinny blondes like myself, however a few of them had started to chunk up a little bit since finishing highschool. Since turning 18 a few months ago, I’v been wanting to put in more effort to see Sammys friends because… well really it was because I enjoyed watching the chunky ones getting fatter. This was my chance and hopefuly it’d become a more regular occurance.
I looked myself over in the mirror one more time. I sure did look hot. Was my ass a little curvier than usual?
The doorbell rang again… Why hadn’t Sammy gotten it?
I rushed out of my room, towards the front door, passing Sammy’s room in the process. Loud music was blasting from it… I’ll deal with that later.
Opening the front door, I was greated by two of Sammy’s skinny friends; Ashleigh and Teigan, both of whome clearly worked out, their bodies toned and tanned. Raven haired Teigan smiled as she walked past followed by blonde Ashleigh. I always felt slightly competitive with Ashleigh as a fellow blonde. Behind them, another blonde emerged. This one was quite round, a friend of Sammys’ I’d not seen in sometime, but clearly had put on weight.
“Hey Izzy,” Jess said as she walked in. Jess was, for lack of a better term, the stupid friend. Just looking at her you could tell that there wasn’t much between the ears. But her chubby belly was starting to hang and her boobs were getting massive. This girl sure was bigger than last time I’d seen her. I loved it.
Two more were still to come. Casey arrived, another skinny blonde, the ring leader of the group and a classic popular girl. She walked past me, not even giving me any eye contact and immediately joined the other girls in the living room. She looked at Jess’ plumped up form, probably about to make some bitchy comment, but we were soon distracted by the groups final guest…
Bailey stomped her way to the front door. I didn’t even recognise her at first. She looked like a completely different person, infact she looked like a person who’d eaten a person… maybe a few. Bailey had always been thin amongst the other girls in high school, but shortly after high school, she plumped up. Puberty right? She got fat. Not Sammy Fat. Just fat. But now Bailey was almost the same size as Sammy, maybe even slightly bigger? It was hard to tell, with her fat being belly and boob focosed compared to Sammy’s butt and thigh focused frame.
Bailey was colossal. A true beast of a human. Her massive, spherical belly hung to her knees and stuck out a meter infront. Her boobs, massive and swollen jiggled ontop of her heaving stomach as she tried to catch her breath. Her face, her previously cute, chubby face, was now so swollen that she could barely see past her fat cheacks. Her neck, if you can call it that, no longer existed. It was simply a role of fat between her head and shoulders. She was sweaty, her brown hair messy. She’d clearly had a rough time walking up the drive from her uber. But possibly the most startling think to me, was just how tight her skin seemed all over. It was as though she’d blimped up so fast that her skin hadn’t had time to accomidate. Her fat riddle arms looked like they were about to tear open. Her face was about to pop. Her belly about to burst.
“Holy shit Bailey, you’re massive,” Casey splutter out.
Bailey looked down at her bloated, bimping belly, clearly ashamed of what she’d become. I couldn’t believe Bailey said that, although it did arouse me slightly. Ugh, this fetish was starting to get out of control.
“I know I’ve put on a bit lately, but I’ll work it off by summer,” Bailey lied as she squeezed through the front door and waddled her way towards the lounge. I watched her jiggle away, in awe at this fat beauty.
“Honey, you’re gonna have to learn to put the fork down, if it wasn’t for Sammy, you’d literally be the fattest person I’ve ever seen,” Casey continued. Great, confirmation that my project was still fatter than this blob. Speaking of which, where is she?
“I’ll just go check on Sammy, you guys make yourself at home,” I said, walking down the hallway. I glancd behind me, noticing Jess had brought a bag of McDonalds with her. Bailey look at it, enveous.
Music continued to blast from Sammy’s room. I knocked. No answer. I yelled. Still no answer. That’s it, I’m going in.
As I slipped the door open, I heard creaking coming from the room. Opening the door further, I saw possibly the most insane sight I’d ever seen.
Sammy, in only her underwear, was laying on her big bloated belly, her hips swaying from side to side causing her ass to jiggle and slap endlessly. I was once again blown away by just how big my sister was. I could see her thick, fat hands grabbing her ass, squishing it, grabbing it like dough. She moaned. Was she pleasuring herself by feeling her fat? Did she enjoy getting fat just as much as I enjoyed making her fatter?
Suddenly the bed creaked loudly as she attempted to role over. Clearly this was a challenge.
THUD!
Now on her back, her massive belly rising into the air, she grabbed her belly with both hands. They grabbed deep into her fat and she began to jiggle it violently, moaning intensley. It was hard to believe just how much fat i could see. Suddenly she reached out to the bedside table which was… full of so much food. Pizza, burgers, doughnuts, chips. She began violently eating them so, so incredibly fast. She was finishing big, juicy burgers in only two bites. Dougnuts she seemingly ate whole. I watched her devour it all. Cakes. Pastries. Chicken Nuggets. I watched as her belly expanded outwards further, fuller, fatter. Suddenly she reached her hands under her belly, struggling in an attempt to reach-
“Sammy!” I yelled over the music. Watching her eat and jiggle was fun, but I was not about watch her pleasure herself like that.
Sammy looked up at me, startled. She desperately tried to jump up but failed, her belly was just to bloated.
“It’s okay, let me help you up,” I said, grabbing her fat, sweaty hand. I pulled. She pushed. With all our strength, we eventually got her onto her feat. I looked at her now empty bed, a massive dent left where she’d been laying. There was also something else down there, a letter?
“I’m so embarrased, how long were you watching for?” Sammy asked as she waddled over to her wardrobe.
“Far longer than you’d like,” I chuckled. “Do you… like being fat?”
Sammy looked taken back. Her face flushed even redder. I could see her desperately attempting to find an excuse as she grabbed her dressing gown off the hook. No use. She told me the truth.
“Yeah…” she puffed, “I kinda find it… sexy? You used to bring me so much food and I loved to eat it and the more I gained from it, the more pleasure I got out of it.
Sammy turned her back to me, her ass was still red and still hadn’t stopped jiggling. She began to wrap her dressing gown around her, looking at herself in the mirror.
With her back turned, this was my chance. I grabbed the letter that she’d apparently been pleasuring herself to. It was a doctors note with the results of some blood tests. She was positive for type two diabetes.
“You’ve got diabetes?” I asked. Sammy turned on the spot, her face startled, her dressing gown struggling to remain tied up.
“Yeah, yeah but it’s fine…”
“Were you pleasuring yourself to this?”
Sammy paused, once again desperate to find a way out… but once again, I got the truth.
“Yeah… I guess I just find that it reafirms just how rediculously fat I’m getting. It makes me feel helpless and out of control. I know it’s fucked up but-”
“Don’t worry,” I cut her off, “I get it. I’m still figuring it out too, watching people fatten themselves that big, that’s kinda my kink.” She was being honest so why couldn’t I? “I think that’s why I’ve always being trying to fatten you up, even before I’d hit puberty I just always had an urge to make you… really big.”
“I’m kind of obssessed with getting bigger,” Sammy admitted. “I don’t know that I can ever stop, even with these health risks…”
“And I don’t think that you should,” I admitted. Was this really fucked up? Was I sentencing my big sister to death? I don’t know. It probably won’t go that far. Probably. But I’d be lying if I said i wasn’t getting turned on. “So does this mean I can, actually properly feed you now, without trying to hide the fact that I’m trying to blow you up?”
“I mean you wern’t very good at hiding it in the first place,” Sammy laughed. Her entire body jiggling. We were just getting started with her. She was about to get so much bigger.
“Your friends are all here and… let’s just say I have a bit of a plan for them too.”

Wonderfully devilish story, I really adore your writing style though it could use a quick proofread. There's quite a few typos and out of place words but overall, I'm a big fan of it!

I really enjoyed this. I loved the idea of the skinny sister fighting the temptation of just fattening a little.
