My New Step-Sister Part 6

Operation fatten Sam was going so well! A month into the new school year is when I finally started to see progress. It was a long four weeks, but I knew this day would come. The changes were very little, almost imperceptible, but for someone like me who was looking at even the smallest of details, it was clear a day.

Sam was pretty much the thinnest girl at school, emphasis on the word 'was'. She was still super thin, much thinner than I, but her belly was showing just the smallest signs of softness that had never been there before. I wanted to poke a finger in just to test how soft it was. Again it was a very small amount, but compared to the rock hard slab she had before, this was a major change.

But my work wasn't done here. I didn't want a little pudge on the queen tormentor of my school, no I wanted her to be fat, as fat as the girls she ridiculed day after day for the last 12 years of our education.

My monkey see monkey do philosophy had worked this far, so I decided to continue with it and see what else I could convince Sam devour. Since it was candy season, I decided chocolate bars and sugar drops were the perfect temptation for my growing sister. I grabbed a healthy stock at the bulk store now that the shelves were full of it, and proceeded to lay my trap.

It was a lazy weekend, so I sat on the couch enjoying some time off, munching on some high quality mass produced candies, waiting for Sam to catch me. It didn't take her long to find me, and she couldn't help but make a comment.

"What are you doing?" She asked in her now common disgusted tone.

Of course I had to play it off like I didn't have ulterior motives. "Oh nothing, just enjoying some halloween candy."

"Halloween? Madigan, it's October first!" She complained.

"Whatever." I shrugged off. "Halloween deserves an entire month. Either way the candy is delicious." Come on, come on, take the bait.

"Well don't eat too much, I think you've put on a few since school started." Oh that bitch, I'll make her pay for that.

"Oh well then maybe you want to take some off my hands for me?" A month ago I wouldn't think this had any chance of working, but with how many extra calories Sam was getting used to, she had to be craving some chocolate at this point.

I could see it in her eyes that she wanted to say no, she wanted to retain some of that strong skinny girl willpower she had mustered all eighteen years of her life. But I wasn't going to let that happen. Lil' old chubby Madigan was a bad influence, and not even Sam could resist this candy.

I could tell the moment her will broke. She took a step towards me, eyeing the treats more than me, the target of her beratement. "I mean, only if you have any good ones, like Reese's or Twix." Sam was getting so susceptible.

"I even have the big Reese's, the ones with the Reese's Pieces in them. Here have a few." I handed her a pile of candy, as much as she could hold. I was really looking forward to those Reese's cups, but I knew they'd look better on Sam's hips than mine.

Sam sauntered off with the sugary treats, and I found almost all the wrappers tossed in her bin later that evening. I made sure to keep the house stocked with her favorites the entire month, and more and more I saw my new sister reach for a chocolatey morsel as Halloween month continued.
