Agree, and offer to help her sister gain weight

    by: Komfy Kat Author IconMail Icon
Sam looked at her fat sister, admiring how thick her legs were, and the way her belly rested heavily in her lap. She couldn't help feeling a stirring in her groin as she took in her sister from head to toe.

"I guess if I'm going to keep your secret, I might as well help you," Sam smiled and grabbed a cookie from the package.

Heather looked confused until Sam gently placed the cookie into Heather's fat mouth. The other girl blinked as she realized what happened, and looked up quickly, "You sure?"

Sam just smiled and fed her sister another cookie. Then another. And another. Then one for herself. Then another for Heather. Finally, the package of cookies was empty. Heather lay back on her bed, rubbing her doughy belly. Sam licked her lips as she watched her sister's belly move like an ocean. She slowly reached out and rested her hand on her sister's middle.

Heather closed her eyes and tilted her head back even further as Sam began to gently massage her belly. Sam loved the feeling beneath her hands. It was like a partially inflated water balloon, except she didn't have to worry about popping it. And it was a lot bigger. Everything about her sister was big. Yet this was nowhere near the size that she wanted her to be. Sam wanted her to grow bigger. Much bigger. Thicker. Fatter. Chubbier. She just wanted her to be massive.

Her hand began to stroke her belly as her sister moaned softly under her. Finally, she couldn't take it anymore. She was going to help her sister get fat. She was going to help her sister's belly grow.

She began to undo her sister's shirt buttons as the other girl's eyes snapped open, "What are you doing?"

"I'm going to help you get fatter."

Heather blinked, still half-asleep, but she couldn't think of anything to say as her shirt fell to the ground between them. Sam climbed onto the bed, though there wasn't much room and slowly wrapped her arms around her sister and pulled herself close. She was so soft and warm. And yet, she wasn't near soft enough for Sam. She needed to be thicker.

The next morning Sam was woken by the stirring of her sister. She didn't even remember falling asleep in Heather's bed. All she remembered was how comfortable she'd been snuggled up next to her massive sister. She wanted more. Her sister looked absolutely stunning in the early morning light. Her fat body was practically glowing.

"Girl's, breakfast is ready!" their mother called from the kitchen, "Hurry up before it gets cold."

Sam reluctantly peeled herself away from her sister and moved towards the door. She took one last look at her obese sister before heading down to breakfast. Despite how much she'd eaten the day before, she found she was absolutely ravenous. She ate more than normal before getting ready for school.

She felt unusually sluggish as she made the short walk to school. Though it was probably because of how much she'd eaten the past couple of days. She would get back to her normal life after today and she could get back to her normal habits, but until then she was going to enjoy her time here. She wasn't sure why she was so out of sorts, but she found she couldn't help it. She just wanted what her sister had.

Sam found her thoughts drifting towards her sister and what it would be like when she was immobile. For she'd already decided that she was going to make Heather immobile. She had trouble concentrating on school as she remembered how good it had felt to snuggle up with Heather the night before. She'd been so soft and warm. She began wondering what it must feel like for Heather.

She imagined herself struggling to walk to school under the weight of her body. She couldn't even bend over to pick up things she dropped as her belly got in the way. She remembered how good that had felt as she sat back down in class after her massive lunch.

As she walked home, she always imagined how it would be to pass by people and have them stare at her. To no longer have to wonder if they could tell she was slightly overweight. She pictured herself feeling the strain of her pants as they began to fit tighter every time she had to go to her room to get something. She imagined her belly getting tighter as the fat piled on.

She grabbed a couple of packages of cookies to eat while she studied. She knew she was a bit behind everyone else since she'd started a couple of weeks into the term. Still, by the time she was finished studying, she realized that she'd finished the entire package of cookies. This was so unlike her. She'd never been much for snacking, and yet she couldn't deny that it was nice not to have to worry about it too much.

Later that evening, after a massive dinner, she snuck into Heather's room and began feeding her all the junk food she could get her hands on. Heather ate mindlessly as she played her video games. Sam didn't mind. She liked just being able to admire her sister in her natural habitat. Enveloped by the massive girl. Grow, she thought. You're so beautiful. Grow.

She stayed up late that night snuggled right up next to Heather. She could gladly do this every night. She felt so safe snuggled up tight against her. It was almost like a hug from her sister. She wasn't sure how long she slept. She just woke up in the early morning hours when she heard her sister stirring. Sam turned to look at her sister and found she still fast asleep, though she was mumbling something about being hungry.

She smiled as she began gently kneading her sister's fat belly before falling back to sleep herself. She wanted to be there when Heather woke up. To show her sister how comfortable she was with herself.

Heather yawned and blinked blearily at the ceiling above her. Her belly heaved slightly as she tried to rid herself of the dream she'd stirred up in her sleep. She couldn't remember exactly what it was about, but it felt so good. She wanted to feel that again. She sometimes woke up feeling hungry for a little bit in the middle of the night, but that was only after the dream. The dream. The dream. The dream.

Heather slowly pushed herself up and looked down at her stomach. Sam smiled as she was awoken by her enormous sister.

Stephen spent some time chatting with Sam about the newest video games he'd been playing. He'd been so excited to find out that she liked video games too. He told her that they'd have to hang out and play sometime. She didn't know what it was, but she felt comfortable around Stephen. Like she could just be herself. However, she found that he seemed to be a bad influence in the food department. Whenever she was around him, she found herself eating a lot more than she normally would. Though it was probably because of how much he ate. It just felt natural to follow suit.

The next couple of weeks went by in a blur for Sam as she tried to adjust to her new life in Bountiful. She'd always been a good student and tried to get good grades, however, she was finding she had to spend a lot of time studying to try to get caught back up. She'd even stopped going on her afterschool jog to give herself more time to study. She'd made a few other friends at school, though she found herself mostly spending time with Stephen while she was at school.

In the afternoon she'd grab some snacks and make her way up to her room to study. After diner, she would sneak into Heather's room and feed enormous amounts of food before snuggling up to her growing sister and falling asleep. She loved what she was doing to her sister. It was almost like getting to relive growing up together all over again.

Heather was starting to have trouble moving around and often got winded really easily now. She couldn't even make it up the stairs without feeling like she was about to pass out. She was bigger than ever, though she still wasn't anywhere near the weight Sam wanted her. But she was getting there. And she seemed to really be enjoying the quality time with Sam. They'd gotten into playing video games together a lot. But she appreciated the time she got to spend with just the two of them, snuggled up on Heather's bed.

Finally, after about a month, Sam was caught up with the rest of her grade. It was a bright fall day with not a cloud in the sky, and she finally had some free time. It was her first Saturday that she'd really gotten to enjoy since arriving in Bountiful. She took her time getting ready and thought about what she wanted to do as she ate a large breakfast.
