My sister

Dear diary,
today was a terrible day, as always really, Mia has been complaining about me all day. Not that I did anything wrong just because she says I embarrassed her by having to go together to class. As you already know, Mia is like 10 times prettier than me, not just her face, but her over all looks, she has that taste of style that everybody likes and her body is just perfect, I guess all the good genes went straight to her and all the bad ones to me. I don't understand really why she has amazing boobs and eat whatever she wants but seems to only gain weight in her boobs and butt, but not to make them way too big, but just the perfect size.
Me, on the other side, always gain weight, and it all goes to my belly. It frustrates me to feel like her life s perfect while I have to deal with all this.

Dear diary,
I had an idea. I am so sick and tired of having to deal with Mia... I can not stand anymore her bad looks at my body, and always trying to make feel bad about myself. I saw online that you can really make someone get fat without them noticing, and I want her to experience how it feels to not be everybody's goal or to have every guy like you.
I have decided to buy some weight gain bars and trade them with the ones she usually have for breakfast. I don't know if it will work, but I hope it does. She has really fast metabolism so I bought this ones that offer to slow it down in order to gain . We will see how it goes.

Dea r diary,
It's been a week and nothing has really changes, Mia looks just the same, I am going to wait for an other week, and if she stays the same, I will get her some weight gain powder to add into her smoothy.
Today she was specially mean about my belly, she started pinching it and saying mean things about it like "look at you fatty" "Lazy fat slob" "You seem to get bigger everyday"
She tries to make me feel bad even if I am not gaining any weight, I am actually trying to work out and eat healthy to loose some weight.

D ear Diary,
It's been 3 weeks since the whole Mia plan started, and for the first time, I am seeing some changes, last week I started adding the powder into her smoothies to speed up the process and bit and it seems to work. This morning she started yelling at my mum about her jeans being too tight, saying that she must have washed them the wrong way. Also, the powder I am using claims to open people's appetite and seems to be working, today Mia took two weight gain bars for breakfast instead of one, that is 600 calories total just for the bars. I hope I can see more changes next month.

De ar diary,
this is going better than I expected, it's been a couple more weeks and oh boy... her belly is not as flat anymore, not something big, but you can no longer see her hip bones, she now had a small layer of fat over them. I really want to tell her that she looks fat, even if she doesn't, just to make her feel bad, but instead I am telling her that she looks way too skinny, so skinny it looks crappy. This way she is trying to eat more, since she doesn't want to be way too thin. I have also started adding sugar into her smoothies, saying that the sugary flavor it's from the new bananas that my mum bought last week, that seem to be really sweet. The best part is that she believes it all.

Dear diary,
Mia has gained quite a bit now,her butt looks bigger and now I can see how her jeans are way too tight, pushing some of her new fat over her love handles. She still wears her crop tops and tank tops but now they are showing more than just a flat belly. My mum had bought her some new bigger jeans since she keeps saying it's the washing machine that is shrinking all her clothes.
Since her metabolism goes now at a quite slow pace, all the food that she used to eat and not get fat are now pilling on her body. The McDonalds she had for lunch, the shakes she drinks after school, her pizza for dinner... I am exited to see more.

Dea r diary,
I can officially say that Mia must have gained at least 25 pounds... Why can I affirm that? Well, because she decided to weight her self... That brings a new problem. Now that she knows how much weight she has gained over the past couple months, she is going to diet to lose it all, or at least that is what she said as soon as she saw the number on the scale this morning. Honestly, I think she is way too addicted to fast food to actually diet, so I think she will just go to the gym and run or something.
Actually this morning she went for a run. I saw her wearing a pair of tight running shorts that now showed some of her new forming cellulite on her legs and squished her little tummy. She didn't last long, about 20 minutes, but it was enough to burn some calories, so I doubled the amount of powder on her shake and added a couple more bananas.

Dear diary,
Mia had been trying to work out more lately, but she keeps gaining weight, This morning she spent about 20 minutes complaining about why she was gaining weight even if she was working out and how she didn't like how her clothes fitted her now. Her belly has grown quite a bit, it now sticks out since she has probably gained about 10 more pounds. Also, her butt is way too tight into her jeans and it's now softer than it used to be. She is not someone you would call fat, yet, but she is getting there.

De ar diary,
It's been a month since I last wrote, sorry. I had exams and also had to turn in some projects and I was way too busy to write anything. Mia had been gaining and she has gone pass the point when she no longer feels comfortable with her clothes, so now she is wearing t-shirts to cover her belly, instead of tight tank tops and crop tops. It'a at home when I get to see her full size. She comes to my room every morning to weight herself. She takes her clothes and stay in her underwear when she steps on the scale. This morning she weighted a 170. As she stepped on the scale I could see her whole body, her belly sticking out of he panties, her love handles making her middle area be the biggest part of her body now. Her butt, that used to be tight and round was now soft and had cellulite. Her legs, where are her tiny legs now? And her tight gap? She no longer had a thigh gap and now her legs touch as she walks. She is now 10 pounds heavier than me, and that is what makes me the happiest. Should I stop here or see how much weight can she gain? I mean, I have already done my job, she now knows how it feels to be me... But... how will she feel if she gets bigger... or even better, how will she look?? Should I stop all this now?
