My New Step-Sister Part 7

I always loved Halloween for the candy, not so much the costumes. I guess you could say I just wasn’t very much in the spirit. Since trick or treating at my age had been frowned upon for several years now, I hadn’t been much concerned about costumes for some time, that was until this year. I had gotten invited to a halloween party, the biggest senior party of the fall, so of course I had to wear a costume.

Normally I just wouldn’t go, and would rather skip out with some friends, tp some houses, or raid the candy dish as I pretended to hand it out to kids. But not only was I invited to this party, but also little miss popular Samantha Fletcher was as well, and I couldn’t pass up this opportunity.

Sam, at least since high school started, had prescribed to the notion that Halloween was the perfect opportunity to dress excessively slutty, if you’ve got it, flaunt it mentality. Well Sam had always had ‘it’, that was until this year. In my hyper focused state, I had been privy to Sam’s slight gain, and growing soft belly, but no one else at school, save for maybe the girls locker room, had been much the wiser. That would all change at this party.

Sam had already showed off her costume to me, using it as an example of what girls my size were not supposed to wear. She had ordered a skimpy pussy cat costume, detailed with pink fuzz and a black bustier. Thankfully she didn’t runway it for me, but from what I could tell, it didn’t leave anything to the imagination. I couldn’t wait for the big reveal on Halloween.

I dressed for the party and headed over with another friend of mine. I said some hellos and grabbed a drink, but the whole time I waited for Sam’s arrival. Soon enough that time was here. There was no grand entrance with horns blaring or anything, she was only high school royalty, not real royalty, but nonetheless I cherished this moment. Her cat costume was as skimpy as I thought and revealed her little belly that I had worked so hard to develop.

I was giddy, but I seemed like the only one. If anyone else had noticed they weren't really showing it. I expected poorly hushed whispers, and glances that lingered as people saw witness to the queen of Beverly High no longer extremely thin trim body. But sadly I was the only one seemingly enjoying this moment.

It was ok, I didn't need to impress anyone else other than myself, and I was proud of what I had accomplished this far. And my work was far from over, it was only October, we had several more months until graduation. By that point everyone would know Samantha Fletcher had turned into what she had always mocked, fat and flabby through and through. I was determined they would all see!

Ok so I put my soapbox away and just continued to enjoy the party. It wasn't long until Sam and I crossed paths, where she decided she just had to comment on my costume. "What are you dressed as, a lesbian?"

I was wearing a baggy flannel and knit hat. "Umm lumberjack, duh." I held up my little plastic hatchet. Again I did very little to put this together, all I needed was the hatchet from the party store.

Sam scoffed and went on her merry way. I tried to enjoy myself during the rest of the party, mostly chatting with my friends and avoiding any excitement. Bobbing for apples in the yard or mosh pitting to heavy music was certainly not my thing. The one thing I did do though was try and keep eyes on Sam as much as I could.

She of course was doing her normal Sam thing, talking with all the school hunks, bossing anyone in her posse around, and making fun of anyone she felt like. One new thing new I noticed though, Sam was quite the snacker that night. Ever time I turned around I felt like I saw her sticking her hand in some sort of snack bowl, or unwrapping another bite of candy. When the party started it was clear to everyone that she had a soft belly now, hours later she looked more like she had a food baby.

I ended up leaving a bit early from the party. Things were starting to ratchet up when some college guys showed up with a bunch of beer. I was no prude or anything, but I just didn't feel like dealing with the cops, but more accurately my annoying classmates when they were drunk. I did see Sam pop the top off a beer though before I left. I did a double take to check if it was light beer or not. I smiled as I walked home… it was not.
