Custom Creations - My New Step-Sister Part 2

Here is the second part to JLB's story prompt about two pseudo step-sisters getting fat. I hope you like where things are going. Leave a comments about what tactics you want to see Madigan use to fatten up Sam.

I maneuvered my way to my new bedroom empty handed. “Glad you could finally make it.” Samantha hissed as she handed me back my bag. Before I could get a word in, she was already laying down ground rules. “Now my room is over there, and this bathroom you see here, yeah well it’s my bathroom too, so make sure to lock both doors when in use. And I shower precisely at…” I kinda stopped paying attention halfway through. My eyes just kinda glossed over, watching her mouth flap open and closed.

I couldn’t help but get lost thinking about my new sinister plan, watching Sam grow big and flabby, bigger than any girl in school. I just didn’t quite know yet how I was going to pull it off.

“Are you even listening? Or are your ears clogged with fat too?” Sam yelled in anger.

I finally said my first words to her all day. “Don’t worry new sis, we are going to be such besties, and everything is going to be great!” I said with the fakest of smiles. I figured I’d play the kindness card and see where that got me, even if we both knew it was a facade.

Sam just huffed and walked away, unable to deal with my neglectful optimism. I spent the rest of the afternoon unpacking my things alone, while my room slowly filled with the decor from my last one. It wasn’t until dinner time that I rejoined the family. I was excited to see that my mom had been making dinner, at least one thing in my life wasn’t about to change.

Sitting down, I scooped a big heap of cheesy pasta onto my plate. Before I was even able to start enjoying it I had to hear a distasteful comment from my new sis. “Ugh! This is what we are having for dinner? I’d rather just go hungry.” Somehow I felt like this wasn’t the first time she had tried to go on hunger strike.

But this was the perfect opportunity for me. “This is a Hannigan classic, and it’s a rule we always clear out plates, right mom?” I asked, looking to get the parental approval I needed to bury Sam.

“Yep that’s right!” She agreed with me.

“No wonder you…” Sam was about to spat until she realized the mixed company she was in. “have such a HEALTHY appetite.” She finished with a much more cheery tone.

“Here Madigan, why don’t you serve Sam up a plate?” Mom asked me, handing me one of the clean empty plates. Randy was just deferring to my mom at this point, since it was our first night here and she had been the one to cook the meal. If she was happy he was happy. I kinda liked that about him, especially when it worked in my favor.

“My pleasure.” I said with a devilish grin. I didn’t want to go overboard on our first night, so I heaped on as big a pile as I gave myself. ‘That should get things started.’ I thought to myself.

Sam looked quizzically displeased by the meal and it’s portion size, but even she had to admit that cheesy pasta was darn delicious. Her first few bites went down easy, but after eating half of it I could tell she didn’t want to finish the rest. She had seemingly met her calorie quota for the meal, but that just would not do. “Remember Sam, clean plate club.” I jingled as I took the last bite of my meal.

Sam grunted, and forced down the rest of her plate. In the back of my mind I just wondered how many weeks it would be before I could start encouraging her to have seconds. I helped my mom with the dishes since I’m the world's best daughter, and also Sam had to go nurse her cheese and carb overload. While I cleared the table I planned my next attack. With the clean up finally done, I was ready to make my next move.

“Mom, you think we could have a big family breakfast tomorrow? I just want to get closer with the Fletchers.” I knew she would eat that right up.

“Of course baby!” She was so excited.

“Thanks mom!” I said exuberantly, but not for the reason my mother believed.

I retired up to my room for the evening, only running into Sam while brushing my teeth. She gave me a stern story about staying in my own lane, and that this was still her house, and nothing was going to change. Pretty much she told me to leave her the hell alone. Sorry sis, that wasn’t going to happen. You invited us into your home, and here we were going to stay.

I laid down for the night with a big smile on my face picturing Sam chubbier, then plump, and finally completely fat. I knew if I played my cards right I could make all of that a reality, it would just take one day at a time, and I had already gotten started.
