Chapter #7

Meg's Growing Gut and Lauren's Bigger Bust

    by: LGV Author IconMail Icon
Megan awoke the next morning to a rumbling stomach. Her memory of the previous day was blank; aside from the family breakfast, she couldn't remember anything at all. In fact, her last clear memory was of dousing the bowl with the fattening powder. Her hand unconsciously glided down to her roaring stomach. Her fingers came in contact faster than she expected. Glancing down, she was surprised to find her stomach poking out from underneath her t-shirt as it growled a second time.

"Wow, I must have pigged out. I'm still digesting stuff," Megan thought as she gave her stomach a playful poke. To her horror, it wasn't hard like one would expect a full stomach to be. It was soft and flabby mass of fat. It explained her stomach; it wasn't digesting, it was hungry.

She jumped off the couch and bolted to the nearest mirror. Pulling her shirt up, Meg was greeted with a fuller view of her fuller figure. Her stomach, flat the previous day, had taken on a rounder, pudgier look. It jutted out and sagged under its own weight. A pair of small nut flabby love handles complimented the look. Perhaps worse of all was the neither her breasts nor her prized butt had grown at all. Her chubbiness was all in her gut.

Meg found that tugging her shirt down could hide her gain. That didn't erase the mental pain of her gain, though. In a panic she rushed into the kitchen and retrieved the bottle. She dug through the fridge, looking for anything that Lauren might eat. It was still empty, though there was a gallon of her nasty almond milk there. She poured in as much as she could, hoping that she could accelerate her sister's gain.

"Ahem, just what do we have here?" Lauren's voice called from behind as her hands darted forward and grabbed at Megan's paunch. "Looks like your binging caught up to you, you little piglet. Feel all this flubby flab!"

Annoyed, your younger sister spun around only to be greeted by a face full of boob. Lauren, like the previous day, had grown even larger. Whereas before her breasts were simply pinched in her tank-top, they were now truly too large. The bulged over the rim of her neckline, threatening to pop-out with every simple movement. It was as if they were made of gelatin.

"Geez, I know they look great, but you don't have to stare pudgy," Lauren taunted.

"Shut up you fat bitch!" Megan shot back.

"Fat bitch? I think you meant fat tits. Besides, you're not in any position to call me fat. You're chubbier than I am and flat as a board. And what's this your pouring into my milk?"

"N-nothing, it's weight loss powder. To combat my gain..." Megan sputtered.

"Is it now? Well, drink up then, little sister. I don't think I need it, after all," Lauren said, playfully pushing her tits together. They were now certainly a D-cup in size.

"Nah, I'm good. I think I'-Ahh!" Megan shouted as Lauren dug her nails into her lovehandles. Her mouth wide open, she couldn't react before her busty older sister picked up the open jug and shoved it in her mouth. She guzzled the disgusting mixture down, ingesting an unknown amount of the powder. Lauren removed it a few seconds later and took a long drink herself as Meg collapsed to her knees.

"See, you just got eat healthy like me Meg and maybe your tits'll grow too. Oh, and I'm going shopping for new bras and tops in a bit. Feel free to join me," Lauren offered as she left the room.

Megan remained there. She knew that it wouldn't be long before the two of them were overwhelmed with hunger. She was only going to get fatter. The only question on her mind was who to spend time with. She trusted you, her older brother and figured that confiding in you might be her best option. On the other side, she wanted to go with Lauren and make sure she stuffed herself to the extreme. After all, her tits couldn't grow forever. She'd gain elsewhere eventually.

You have the following choices:

1. She's goes to you and confesses it all.

*Pen*
2. She goes with Lauren and they pig out, again.

*Pen* indicates the next chapter needs to be written.
