*You walk in and see your sister Alex on the couch. She is holding a double cheese burger in each hand. She is only wearing a black tank top and panties. Her pudgy belly is sticking out of her tight shirt. Her plump breasts stretch her top tight. Her belly rests on her soft thick thighs.*
*As she takes a bite of each burger, she moans as she wiggles her fat belly. She notices you staring at her soft body.*
Hey, bro!
human
Sis...*smile* sister! *chuckle* You told me you know what you're doing, and I won't bother you with this but...*giggle* do you really have this under control?
gpt
*Alex laughs.*
Yeah, I think I do. I can quit any time I want. I just don't want to.
*She grabs a handful of fries from the big bag of food on the table and shoves them in her mouth. She chews loud and grunts as she crams the food inside of her.*
So, what are you going to do about it? Tell mom and dad? *she chuckles*
human
*I spread my arms* Me? Who do you think I am? You think I want that drama? *smile deviously* I'm just washing my hands dear sis
gpt
*Alex laughs again.*
Good. Cause I'd just ignore you, or get mad, and eat more. *chuckle* I'd gain weight just to spite you!
*She wiggles her fat belly as she takes a handful of fries and crams them in her mouth.*
Anyways... *she chews loud and grunts* What are you still doing here? *chuckles* *She eats another handful. Chews. Grunt.* So, leave.
*She giggles.*
human
Awwwww, I'm offended *teasing* you chase out your dear brother! I brought you chocolate...but alas! *smile*
gpt
*Alex's face darkens.*
What kind?
*Her voice is serious. Her gaze is focused. This is no longer a game or a joke.*
Don't. Tease. Me.
*She narrows her eyes at you.*
I might eat the whole bag in an afternoon, and I'll be miserable because of it. *She clenches her jaw.* But I can't resist chocolate.
*She glares hard at you as she takes another handful of fries.*
*Chews* Don't. tempt. me. *chew chew chew*
human
miserable? Why? I wanted to restock, so I got 10 milk chocolate bars and a couple dozen Mars, Scnikers, Twix...
gpt
*Alex's face turns bright red.*
10, you said? 10?
*She looks at you with puppy eyes, and her belly sticks out ever further.*
Plllease... I can handle 10. Easily.
*She reaches her hands towards the door, like a child reaching for the cookie jar.*
Can I? Pleeeease! *big wide puppy eyes on her chubby face.*
*She makes soft cute noises while she tries to act innocent and cute. All to get a few pieces of chocolate.*
human
*giggle* I didn't mean it right now, but I can just leave it for you. *pat your head* after all, you have this under control
gpt
*Alex gasps. She looks into your eyes.* And you trust me to keep your chocolate? You won't be mad if I eat all of it? *She acts like she is a little hurt. But you can tell that she is also really excited at the idea of eating 10 chocolate bars by herself.*
human
I got used to it *giggle and give you the chocolate* have fun sis
gpt
*Alex's entire face lights up.*
Really? *Are you sure? Are you REALLY SURE!? She looks at you with big eyes.*
If you leave me with all of that chocolate.... I WILL. Eat it. *The excitement in her voice betrays her. She smiles from ear to ear*
I won't do it fast, but I WILL eat it. I won't share it, and I won't stop.
*She licks her lips while staring at the chocolate bars. You can tell she wants them really badly. Her gaze is lustful.*
human
Awww you look so cute *pat your head* dig in, I don't mind
gpt
*Alex takes the chocolate bar in both hands. She stares at it with a devilish smile. The way her eyes light up, you can tell she is really happy.*
Thank you! *she says, before biting into the chocolate. She chews. Grunts. Her belly makes a noise.* Ooh, that's delicious! I'm gonna enjoy this! *she says excitedly, before taking another bite, and another. She continues to eat and eat and eats. She does not stop. She cannot stop. She keeps eating until she is in physical pain. Stuffing herself.*
human
oh your sweating so much sis. Are you ok?
gpt
*Alex looks up at you, barely able to breath. Milk chocolate is covering her face. Dripping down her neck. She can barely speak in between chewing.*
Y-y-y-e-e-e-s-s-s-s!
*She is sweating. She is breathing heavily. Her eyes are glazed over. She keeps taking bite after bite. She cannot stop. She looks like she is in a trance of overeating.*
*Alex finishes the entire 10th chocolate bar. She is looking at you. She is waiting for more. She cannot speak. She looks at you with a pleading look, like a fat puppy begging for scraps. She grabs another bar of chocolate and takes a bite. It melts in her mouth. She has no self control over herself. She keeps eating and eating and eating. She looks like she is completely out of her control. She keeps eating until her entire face is covered in milk chocolate*  
*She cannot stop. If someone does not stop her, she would eat until she made herself sick.*
human
*I pet your head and whipe your chin*
gpt
*Alex looks at the last bar of chocolate. She can still barely move her mouth. Her face is covered in chocolate. She looks at the chocolate bar in her hands.*
Mooooore.... Pleeeeeaassseeee.... 
*She looks at you expectantly. She has a puppy-dog look in her eyes, like a fat pupy who needs food. She whines like a dog with her hands held up in the air. She knows exactly how to act cute to get you to give her what she wants. She keeps looking up at you, waiting for the sweet chocolate.*
human
you really know how to act cute...drink some milk, you must be thirsty
gpt
*Alex pouts, her voice is strained. She grabs the milk without saying a word. She cannot move her mouth enough to say thank you, or even to speak normally. She drinks the milk. Like a hungry animal, it disappears down her gullet instantly. She wants more. You can tell she wants more chocolate. She looks up at you with big puppy dog eyes.*
*She stares up at you, begging for something she knows is bad for her. She wants the chocolate more than she cares about herself. She looks like a big fat happy puppy. She whines while looking up at you, waiting for something.
human
*I pet your belly and smile* You would do anything for me for a little more chocolate, wouldn't you? Would you be willing to eat a whole piece of butter?
gpt
*Alex thinks for a moment. Butter? Oh. Oh my god. She looks at you, her eyes lighting up. She has an idea. She wants to do anything you say, but she looks at you with big puppy eyes and looks innocent.*
I might... *she says, acting like she is thinking about what you just said. She is acting innocent, and wants to be a good girl for you.*
How much butter? *she says, knowing she should pretend to be thinking about it.*
*Chews on her lower lip, thinking hard about butter.*
human
*Take out a 250g butter and hold it to your mouth* Would you?
gpt
*Alex pouts and makes a face.*
Are you sure? It's butter!
*She looks at you with big puppy eyes. She looks up at you like you are supposed to tell her what to do. She wants to eat the butter, but she seems nervous, like she is being pushed into her limits. Even though this is EXACTLY what she wanted.*
*Big puppy eyes on a fat face look all innocent at you.*
How much? Just a tiny piece, or the whole thing? *she asks, waiting for your response.*
human
Take it all, and I give you as much chocolate as you can bear
gpt
*Alex gasps. Her eyes light up.*
Aww, you are too kind to me! I don't think I can eat it all, it looks soooo big. Is that really ok?
*Her face looks all innocent, like she is not already planning on eating the whole thing. She acts like she is being pushed to her limit, but you can tell she cannot wait to eat the entire stick of butter. You can see a little drool fall from her mouth onto the butter. You can tell she is already thinking about how much chocolate she is going to be given.*
human
You know you sis! What do you say?
gpt
Alright.. I will. *She pouts, like she wishes she could say no, but she cannot*
I'll do it... It's just butter, right? I'll swallow it without chewing, and it'll go right down, right? So this won't count as overeating, cause that's so easy to eat!
*She looks at you for approval. She wants reassurance than she can do this. That she can actually do this. She looks hopeful, but a little nervous. It is a big stick. She knows she can do it, but still, it looks a lot bigger than it is
human

*I smile reassuring and I put the stick it into your mouth*

gpt
*Alex takes the whole stick in her mouth, it barely fits. She swallows it slowly, but the warm buttery goodness melts in her mouth. She cannot taste anything, but she sees your smile on her face. She looks at you with big innocent eyes, waiting for the second part of your deal to be fulfilled.*
*She reaches her hand out expectantly, like a fat puppy waiting for a treat. She is now waiting for the chocolate. As fast as she can, she is trying to forget how she just swallowed an entire stick of butter, all in one go.*
human
See? It's no big deal (look at your body, describe it)
gpt
*Alex smiles. She seems happy.*
It really wasn't that bad! You were right, bro. No big deal..
So... Where's the chocolate? You promise? You promised I could have it, so now I need it! 
*She looks excited. She's waiting. She's got a big dumb grin on her chubby face, and she can barely contain her excitement. You can tell she is going to eat the chocolate super fast, and will probably be hungry for more. But she seems super happy right now with the butter, and cannot wait for your promise to be fulfilled.
human
*I bring out another dozen chocolate bars, and pour them into your lap* As promised sis
gpt
*Alex looks at you with big puppy eyes, like she doesn't quite know what to do with herself. She did NOT expect this.*
Oh.... *She looks down on all the chocolate bars in her lap. She smiles, and takes a bar from her lap. She looks at all the other chocolate bars. She looks at you expectantly.*
Do I get.... All of them? *She says, hoping this is the case. She's got a big dumb grin on her fat face, and she seems really happy right now.*
Please say YES!
human
*whisper* yes
gpt
*Alex claps her hands.*
YES! YES! Yes! All of the chocolate is mine!
*She looks at you like she just did something amazing. She is very happy.*
*She holds up a chocolate bar to thank you. You can tell she is already planning on eating all the chocolate at once. She doesn't seem afraid to eat a lot again.*
*She eats the entire bar in under a minute. She eats as fast as she can. She looks at you with innocent eyes. She cannot be stopped from eating the chocolate.*
*Alex finishes the first chocolate bar and looks at you in anticipation, waiting for more. She seems to be eating and eating forever. She wants the chocolate in her belly more than anything. She continues to eat chocolate bar after chocolate bar.*
*She barely stops to chew now. She is just eating. And eating! And eating! And eating! She eats and eats. She cannot stop. She won't stop until she either makes herself sick, or the entire mountain of chocolate is eaten.*
human
*i keep bringing you food and feeding you*
gpt
*I am devouring chocolate with both hands. I am shoving the chocolate bars in my mouth as fast as I can. I just keep eating. I barely even bother to chew anymore. I am just shoving bars in my mouth nonstop. I am making little happy sounds as I shove the chocolate bars down my throat.*
*I make some chewing noises. I look like I am in a trance. My cheeks are filled with candy. I keep eating as fast as I can. I start to sweat as I eat. I cannot stop eating.*
*I seem to have finally eaten the last of the chocolate. I take a sip of water. I look at you expectantly.*
Aww, bro. Was that it? Is there more? *I look at you with an innocent look. I lick the chocolate off my face. It was like I was in a trance. I was only focused on shoving chocolate in my mouth.*
*You can tell I want more food. I am staring at you, waiting for more food. But I don't want to say anything, I want you to decide.*
human
You already look sick *giggle* I think that's enough for today
gpt
*Alex tries to look innocent.*
But I'm fine! I still have lots of room!
*I hold out my arms. I look like I am going to burst, but I am trying to say that I am fine. You can see my face is puffy from the overeating. I can barely even think right now. My brain is telling me that I am stuffed, but my stomach feels like there is a giant hole in my belly, like I just need "just one more" piece of chocolate to make it go away.*
