Thunder Thighs and Bubble Butt

    by: LGV Author IconMail Icon
Your jaw crashed to the floor when you saw it. It was around eight in the morning, and your mind was still weary from sleep, yet the vision of what you beheld was enough to shock you to attention. You had just left your room, intent on cooking a healthy breakfast for pudgy sister that you saw her stumble from her own room a groggy mess.

Though only a day had passed, Meg looked a world apart from when you had sent her out. Her belly, which had been a small layer of blubber easily had grown at least three inches. It now hung defiantly outwards, sagging under its own weight. Even with a t-shirt, you were sure she would be unable to hide her gain. A soft pair of love-handles now clung to her waist, further exaggerating the roundness of her midsection.

That, however, was not even the worst of it. Megan, it seemed, was a pair-shaped gainer. Most of the fat seemed to have found its way below her belt. Her ass, which had just the day before been a chubby little mess had swelled a moderate amount into a bonefide bubble butt, straining the fabric of the gym shorts she had failed to change out of. To the casual observer, it looked far more like she was wearing a thong that in did pants as her growing backside had swallowed it up into itself. She absentmindedly tugged at it as she walked by, still not registering your presence. A

Her thighs had grown as well. Where before they had swished against each other, a slight irritation, they were now absolutely too large for a standard walk. The inner thighs slapped together with each step, a quiet clapping noise following every motion. A true pair of thunder thighs if there ever ones. Finally, perhaps most notably of all, you took notice of a small, though obvious, double chin.

There was no two doubts about it: Megan was fat. Not chubby. Fat.

'Meg, what the hell happened to you?" You shout, unable to control your voice.

"Finally aware of your presence, she swung around.

"Hmm, what are you screamin' about?" she asked.

"Are you serious? Look at you, you're even bigger!"

She gazed down, finally taking in her bigger body. She was shocked, at first, but slowly her surprise gave way to ambivalence. She certainly didn't want to gain weight, but if this was going to help her win, she was willing to take it.

"Holy hell, so that's why your screaming." Lauren said, exiting her room. "You've become a literally fat-ass, Meg!

Meg tilted her head in confusion. Sure, she could understand you being upset, but Lauren? Wasn't she supposed to be helping with the gain?

"Don't be a bitch, Lauren," you said, jumping to Megan's defense. "That said, you really have gained a lot, Megan. What the hell did you eat?"

"Well, um, about that..." Meg stalled, giving Lauren just enough time to jump in.

"This cow probably has snacks hidden all over this house. There's no stopping her! In fact," she began, digging her fingers deep into Meg's fatty thighs, "I think she needs a little punishment. Time for an 8 AM workout!"

"B-but I just got u-"

"And you're already dressed too, come on, let's go!" Lauren ordered, dragging her out by her haunches. You just watched, unsure of what had actually gone down. There was no way that Meg had eaten so much at the house, yet you weren't sure enough to stop her from leaving. Once out of your presence, the two began to discuss their real plans.

"So, I'm not really going to work out, right?" Meg asked in fear.

"Duh, of course not! We gotta keep at your training, sis. And I got just the thing." Lauren replied.

The two got in the car, heading to...

You have the following choices:

1. Commit more food crimes

*Pen*
2. An eating contest set up by Lauren

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