“Maybe you should slow down with the Coke. That’s your third one today!” Mike protested, watching his friend Georgia chug yet another bottle. “Aren’t you worried about side effects or something?”

Georgia snorted as she finished, tossing the empty plastic container into a nearby trash can. “Side effects? Even if anything happens, it can be worse than this.” Gesturing to her curvy Asian body she burped. “Does that count?”

Mike shrugged. “I just think that you should be taking care of your body now.”

“Why? Because I’m supposed to be some skinny hot girl now? I didn’t ask for this.” Georgia grumbled, grabbing her breasts. “I didn’t ask for sensitive boobs, a giant ass and constant attention from horny guys! Plus-” she stopped when a sharp cramp came over her, clutching her stomach in pain. “Umm, maybe you were right about the coke... I feel sick.”

Distracted by her aching tummy, Georgia didn’t notice that her hips were beginning to slowly swell, each cheek slowly expanding as the tight lycra shorts she was wearing began to stretch. Mike, who had been snatching glances at her behind as often as he could, was quick to spot the change. “Hey! Check it out - your ass!”

Scoffing, Georgia gave her friend the stinkeye. “Oh for fuck’s sake, can’t I go one minute without you bringing up my-OMFG!” Finally looking down she was shocked to see that her butt was indeed growing in size. “What the fuck is happening to me! Oh god!” She gripped her cheeks, feeling her already skimpy shorts and underwear ride up her crack as more and more booty started showing. They were quickly approaching the size of basketballs and showed no sign of stopping. “It's growing! I-I can’t be seen outside like this!”

Mike quickly began looking around for a place to hide, struggling to keep his focus off of his friend’s expanding booty. Spotting an unlocked door to a nearby empty classroom, he pointed towards it and started running. “C’mon, we can hole up in there. Hurry!”

Both hands still cradling her gigantic rump Georgia began to waddle slowly towards the building, trying her best to walk with her trunklike thighs as her cheeks clapped loudly together with every step. “I’m... trying... my... best... asshole!” As she approached the door a loud RIIIIIIIIIIIP sound echoed out as her clothes finally gave up, exposing her bare butt to the world. She squealed in embarrassment, worried that she would get caught like this. "Oh fuck, I'm a freak!"

Finally approaching the room she tried to get through the door but accidentally wedged herself in the frame, the girth of her enormous rear too wide to fit. “Oh god, I’m stuck! I’m stuck!” She began to cry, her huge booty quivering as Mike began to push on her ass, one hand on each half as he struggled to force her through. “Push! Push, damnit!” Georgia wailed just before her ass finally gave way, the two tumbling into the classroom.

Georgia lay on her stomach panting, her preposterous posterior sticking out several feet from the rest of her body. Each cheek was now the size of a ripe watermelon and finally finishing its impressive growth. She could also feel something hard pressing into her crack through Mike’s shorts, betraying how much the whole ordeal had turned her friend on... and not only that, but Georgia was beginning to feel a heat in her pussy that she assumed was another side effect of the cola. Quickly her mind was beginning to think of taking cocks, being filled with a man’s seed... and she wasn’t sure how long she could resist.
