My New Step-Sister Part 8

Sadly JLB, the requester of My New Step-Sister had to end their patronage, so with it this story is ending. I was planning several more parts, but decided to jump to the end to give these characters the resolution we were looking for. If someone wants to pick up the mantle for JLB I'd be happy to fill in the middle, but it might not be as satisfying now that the ending is here. I hope you all enjoyed this story as much as I did. I had fun writing from Madigan's perspective. The last part is a bit of a doozy, but I had to do right by these characters to finish things up. Enjoy.

Thanksgiving, Christmas, and New year's all went by in a flash. Through the holidays Sam had plenty of opportunities for large festive dinners and seasonally themed treats. To my chagrin she took advantage of all of these opportunities. Come the New Year Samantha Fletcher was looking absolutely chunky. Now that the floodgates had seemingly broken Sam was gaining weight faster than ever. I constantly saw her snacking on junk food, throwing out fast food wrappers, and eating until her belly was stuffed.

My plan had worked masterfully. Sam no longer resembled that thin high school queen that she had started the year as. She was more like the size of two high school queens. As the winter days melted into spring and our classmates started leaving their layers at home, Sam had no defense against hiding her weight gain. Gaining pounds by the week, it was even easier to see just how flabby Sam had gotten.

As the end of our senior year approached I could tell Sam was reaching a breaking point. Her posh popular friends had stuck around at first when she was just a little thicc, but once she started getting pretty plump I noticed they started to keep their distance. This left more time for Sam to stay home, surrounded by the junk food mecca we had built at the house due to both of our appetites.

One early evening I could hear her struggling with her wardrobe, something that had been happening since the holidays last year, and gotten worse month by month. “Ugh! What the frick! Nothing fits!” She grumbled.

I was quick to jump in and see how I could help my lovely ‘step-sister’. “What seems to be the problem?” I asked, appearing in her doorway. Sam’s room was a mess with clothes everywhere, I guess all of it didn’t fit her flabby physique anymore. It wasn’t just the clothes I noticed though, it was snack boxes, candy wrappers, chip bags. None of this were new though, Sam had been snacking away day after day in her room for months now.

“Go away Madigan. I’m just trying to find something that fits.” She gnarled, not even looking my way, rather grabbing a couple of oreos of package on her shelf.

“You’re not going to wear that are you?” I asked, referring to her pants, which looked painted on. “No offense, but they make you look kinda fat.” I couldn’t help but smile.

That got her attention. She turned around, looking me dead in the eye, growling in frustration. “You! This is all because of you!” She started marching towards me, her belly jiggling as it hung free from her too small shirt. I started backing up defensively. “I was just fine until you moved in, and then… and then...I...I caught your… fatness!”

“You can’t catch fatness.” I calmly replied, knowing full well it was me that had transformed Sam into everything she had looked down on in the past. “It’s not my fault you are fat.” I lied.

Sam’s epic weight gain this year had been music for my eyes. Quickly I learned that Sam was going to be top heavy. At first I was worried this was just going to leave her with big boobs, but all along her stomach kept pace as well. Starting out as a little pot belly it had grown into a chubby gut that hung over waistbands a few inches and jiggled at the slightest movement. At this point she looked bigger than I did at the beginning of the year.

Sam was visibly agitated, but this was my big moment, this is what I had worked for all year, and I was going to relish in it as much as I could. The thing I wanted most, more than anything in the world, was to see how much she weighed, I couldn’t tell you how much that would delight me. So I tried to steer the conversation in that direction as best I could. “There there Sam, I’m sure it’s not that bad. Do you want to borrow some of my clothes?”

“I’m sure you have plenty to wear, you know all about fat girl clothes.” Sam scoffed. “Just leave me alone, I can feel myself getting fatter just being in your presence.” Maybe that has something to do with the almost empty packet of Oreos you bitch. “At least being around you I can feel somewhat small.”

She did kinda have a point there. I said Sam was now probably bigger than I was at the beginning of the year, but she certainly wasn’t bigger than me currently. All the time I spent encouraging Sam to eat, I had been right there in the trenches showing her the way. Plus I wasn’t going to deprive myself fully just to get Sam into fat girl status. So I put on a pound or two, I was ok with my body and had accepted the fact that I was already a fat girl.

“Samantha Fletcher, always able to look on the bright side.” I said sarcastically, digging a chubby hand into my fleshy side. “Well my size doesn’t change the fact that you got fat, I bet you’ve even gained more than me pound for pound.”

Sam shot me daggers again, offended by my assumption. To her I was a fat girl through and through, and she was just visiting. “How dare you! I bet everyone you spend time with gets swept up into your junk food vortex. No one is as fat as you Madigan.”

Perfect, my opening was here. “Well if that’s the case, why don’t we take it to the scales and see who's gained the most this year?” I tried to hide my excitement, but I know I couldn’t.

“Why do you think I care about how much of a fat pig you are?” Sam dismissed.

“Well let's make it interesting then. Whoever gained the most buys dinner, winner picks the restaurant.” I couldn’t control myself, I was loving every minute of this. Sam was so competitive and headstrong I knew she couldn’t pass this up. Also she was rubbing her belly like she was mad hungry.

“You’re on tubby! You better grab your wallet now.” She chided. I just turned around and made my way to the bathroom where the scale was, my new found waddle more pronounced than ever.

“Why don’t you do the honors?” I suggested to Sam. “You were what like 110 last September?” Sam nodded in agreement before gingerly stepping on the scale. We both dashed to look as soon as the number showed on the digital display. “Two fifty!” I couldn’t hide my excitement any longer, and Sam was too preoccupied to notice.

“Two fifty?” Sam sulked. “Holy crap I didn’t think things were that bad, god damn I’m so fat.” Sam seemed to be on the verge of tears.

“Well maybe this will make you feel better.” I hopped on the scale, pulling my belly back with both hands so I could read the result. “I was like 220 at the start of the year, and now… *omph* 320. Wow I gained 100 pounds this year.” I was kinda embarrassed but also a little excited. I was seriously fat now, not just a chubby high school girl. I would not have gained that much if it wasn’t for helping Sam along, but unlike her I didn’t mind being a fat girl. “Well either way still looks like I won!” I declared after doing a little simple math. “Can’t wait to get to the Country Time Buffet!”

Sam just looked at me puzzled. “How the fuck can you think of eating at a time like this? The scale just proved we are both porkers, with you being probably the heavy weight of the school."

"Come on Sam, it's not like we got this way from starving ourselves and eating salads. It's 4pm in the afternoon, can you seriously tell me you're not hungry?" I knew she was but would never admit it. Sam had been chomping on something 24/7 for months now, the girl was always hungry and craving. "Plus the beauty of a buffet is you can eat as much or little as you'd like. You can eat nothing for all I care, but I'm gonna take full advantage of my free meal. A bet is a bet."

Sam backed down, my reasoning skills always made me feel like a courtroom lawyer. We hopped in Sam's car, something that was getting to be kinda a tight squeeze with two bloated babes such as ourselves. Soon enough we arrived at the Country Town Buffet, home to almost anything you wanted to eat. After paying to get in, our options were endless. There was fried chicken, pasta, tons of different meats, salad (yuck!), burgers, mac and cheese. It was just endless possibilities, and every new station you visited you'd find something new and tasty.

I grabbed a plate and started loading it up immediately. French fries, chicken tenders, mozzarella sticks. If it was fried, it was mine. Waddling back to our table with a full plate and a tall glass of Coke, I noticed Sam returning with an equally rich meal. So much for controlling her porky tendencies. I just smiled and started in on my meal.

One plate wasn't nearly enough and Sam and I made several trips back up to the buffet. I was somewhat surprised Sam was going almost plate for plate with me, even after the shocking realization that she was closer to 300 pounds than 200. How could I be shocked though, I had turned Sam into a glutinous eating machine. I watched as she lumbered off to the buffet to fill yet another plate. Her round bubble butt tested the stitch strength of her pants, expanding sideways as much as it had grown out. On her way back you could see really where all of her weight had landed. Her belly, which had now pushed her woefully undersized tee shirt further up, jiggled with each step. Rolling over the waistband of her pants, it hung a few inches over her belt. Her love handles could not be contained either, and seemed extra puffed out due to her right pants. Lastly her knockers stuffed into her top looked like two massive fleshy pendulums swinging back and forth.

Operation fatten Sam had been a rousing success, more than I had ever hoped for. Although I had wished for results this good, back in September I never thought it'd go this well. And it wasn't just Sam's weight that shocked me. I didn't think I'd be over 300 pounds come the end of high school either. I guess that's what happens when you enjoy food as much as we do.

At this point I could only think of the future. Sam and I would both be attending state college in the fall, and I overheard my mom saying she wanted to get Sam and I roomed together since we've done so well this year. I was going into school undeclared, but I think I'm gonna switch to a culinary major, I've heard they all get rooms with a kitchen.

I couldn't count how many plates we both art, but I can tell you we were both stuffed as we waddled back to the car at half the speed we had entered. On our way out we passed a group of girls, probably sophomores or juniors at our school. As we lumbered by I heard one of them say, "If I ever get that big, just kill me." To which her friend responded. "Like totally. Gees hide that belly would ya?" They were talking softly enough, but if I could hear them I know Sam could as well. Hopefully now she knew how it felt to be picked on for your weight.
