Side Effects May Include

III

Sasha hurried down the city sidewalk on shaky legs. She nearly fell on her face when she tried to break into a jog. Her little “break” in the buffet restroom had taken more out of her than she thought. She needed to hydrate, but she had to find her mistake first.

Luckily, the twelve-foot-tall receptionist was making it easy for her. While Jackie wasn’t leaving craters in the pavement, Sasha could follow the figurative impact of Jackie’s path through the city. Cars had crashed into poles, trees, and other cars. A fire hydrant gushed water into a fountain, where a few children began to play. Every cadence and melody of alarms and sirens blared.

None of those signs were necessary, however. Sasha simply followed yet another trail of decimated cafes, convenience stores, restaurants, and food carts. Doors and windows had been smashed in, leaving gaping holes in brick walls or wood and plaster frames. Piles of empty produce crates had been upended and scattered across the sidewalk as if a sloth of giant bears had rampaged toward downtown.

Sasha knew the reality was even more ridiculous. The path of destruction she followed had been caused by one woman. One very tall, very busty, very hungry, not very bright woman. And it was all her fault. Jackie was an adult, responsible for her own actions, but Sasha had known better than to leave her lab unlocked. Especially with an untested formula sitting out on the bench. Nothing in her models had predicted this outcome, but she’d been working with the most potent formulae Madgenix possessed—there was simply no excuse for her negligence.

As she pursued the giant receptionist, Sasha wondered how she would draft the article about this incident. Would it be valuable to anyone at all to know that her formula, combined with the subject’s pollen allergy, created an insatiable boob monster?

That was a problem for Future Sasha. Present Sasha’s priority was to find Jackie and somehow stop her. Before she devoured everything edible in the city, caused billions’ worth of property damage, or both.

She heard the crash and noisy chewing moments before she rounded a corner to finally catch up with her coworker. Jackie sat in a supermarket parking lot and was, of course, eating. Sasha estimated that the blonde was now at least twenty feet tall. Jackie held a shopping cart that looked like a shoebox in her hands, scooping math problem amounts of melons into her maw. Her stomach rested on the blacktop between her spread legs, bloated like a woman in her third trimester. With triplets. If said triplets were baby elephants.

Sasha jogged up to the store’s entrance, where the automatic doors had been ripped off and tossed in a pile of bent metal and broken glass. A middle-aged man she assumed to be the manager was mopping sweat off his brow with his shirtsleeves. He supervised as employees ferried a train of shopping carts from the building, loaded with food.

“What are you doing?” She asked.

“She wants food,” the manager said, as if explaining that the sky was blue.

“So you’re just… giving her food?”

The man turned his full attention on Sasha. “How exactly are we supposed to stop her? She ripped my damn doors off! We’ll get fresh stock on Tuesday. At least this way, she won’t destroy the whole store trying to come inside.”

A crash interrupted his tirade, and the two of them watched the titanic blonde drop her emptied cart onto the growing pile beside her.

“I just hope she’s satisfied before we run out of food. I tried to call for help, but the whole damn system is overloaded.” He took in Sasha’s lab coat. “Who are you, anyway?”

The question dumped a bucket of ice water over Sasha’s head. “I’m, um, nobody… Actually, I should probably get out of here.”

She dashed around the corner of the building before the manager could ask any more questions. Apart from the store employees, she was the only person who hadn’t fled the scene.

Sasha couldn’t flee, of course. She hid behind the building, watching helplessly as Jackie gorged, emptying cart after cart as her towering belly swelled larger and larger.

Finally, the frenzy came to an end. The glutted receptionist sighed, rubbing her hands over her enormous middle.

“There’s no more?” She boomed.

The manager cowered, wringing his hands. “I’m sorry, miss…”

Jackie beamed. “That’s alright, thanks so much for being so generous!”

Sasha watched the massive blonde try to stand. Jackie pressed her hands to the asphalt and shifted her legs. Her truck-sized bottom hovered inches from the ground, but her stomach was simply too heavy. When she landed, dust sloughed off the brick walls of the building, several more car alarms went off in the area, and the retail workers staggered on their feet. Tremors vibrated up Sasha’s legs while slick fluid ran down.

“Say,” Jackie boomed. “Do you have any flowers in there… by chance?”

“Flowers? Um, of course!”

“Oh no…” Sasha breathed.

An employee pushed a cart full of bouquets from the gaping hole in the store’s former entrance. Jackie lifted the entire cart, burying her nose in the blossoms. Her face scrunched, her head reared, and she dropped the cart to brace herself with both hands on the pavement behind her.

Sasha wondered if she should warn the store employees to take cover, but they were adults; they’d figure it out.

“aaAHH… AHHHHH…”

That didn’t mean she had to stand out in the open, however. Sasha darted to a nearby tree, hugging its trunk as a flock of birds took flight above her head.

“CHOOOO!!!”

It was like a shockwave. The large sign above the grocery store rocked on its steel frame in a spray of sparks. The few cars still in the parking lot rocked on their suspensions—several tires left the ground. More glass shattered, and any car alarm not already going off in a two-block radius added its cadence to the cacophony.

Sasha relaxed her grip on the tree. Unlike the employees dusting themselves off and peering up at the giant woman in confusion, she knew Jackie’s sneeze was merely the starting bell.

BRRRRRM

The ground below Sasha’s feet trembled like an earthquake. Jackie’s engorged belly resting on the blacktop rippled and pulsed. Cars shifted from their parking spots like vibrating phones. The mountain of discarded shopping carts spread like a snow pile in spring. The employees grabbed each other’s hands and dove back into the store, despite the clamor of crashing shelves within.

BLUB BLUB BWOOOM

Sasha almost thought she could see the torrent of calories pumping through Jackie’s enhanced digestive system and adding adipose to her breasts. They pulsed and heaved, plumping outward even as the belly they rested on receded. Jackie pointed her toes and stretched her arms into the sky. Sasha watched with fascination as a foot the size of her leg inched closer to the building.

BRrrrRM

Bwooom

Creeeeak

The ground continued to shake even after Jackie’s stomach left the pavement. The store sign wavered and creaked, then swung down like a hinge to crash in a shower of sparks and shattered lightbulbs. Branches fell from the trees lining the sidewalk. Sasha’s hiding place suddenly didn’t seem like such a great idea.

Making one last long, languorous stretch, like a cat sleeping in a spot of sunlight, Jackie’s transformation subsided, and she worked her way to her feet. Sasha’s mouth went dry and, to her astonishment, she felt heat squeezing between her thighs. Jackie’s body was perfect. Long, lithe limbs, trim waist, soft hips, round ass—if she were still a normal height, and had no tits to speak of, she’d turn heads wherever she went. But for all she’d grown taller and taller, her boobs were determined to stay one step ahead. She stood between thirty and forty feet high, the roof of the supermarket reaching just past her navel. With her mind a haze of lust—and Jackie’s continued deviation from the mean—Sasha was finding it difficult to estimate with any degree of accuracy. Jackie’s gargantuan tits blocked out the sun, casting two round shadows across the building and the parking lot below.

As much as she wanted to find someplace private yet again, Sasha knew this couldn’t go on. Another feast like this could make Jackie taller than any building in the city.

She staggered across the parking lot on trembling knees. “Jackie!”

Jackie’s head swiveled, and her shoulders turned. Her breasts followed half a second later, slapping against each other and making her unsteady. She took a few balance-correcting steps, leaving small craters in the blacktop. “Sasha? Is that you?”

“Down here!” You gluttonous cow, she did not add.

The broken ground heaved, chunks of fractured asphalt rising and cracking as Jackie shifted her feet. Craning her neck, Sasha’s view of Jackie’s face was completely obscured. All she saw were the undersides of her bare glands, curving gracefully outward from her torso like twin parabolas. “Hang on,” Jackie boomed. “I can’t see you down there.”

Air displacement blew Sasha’s hair as Jackie squatted, those ridiculous breasts plummeting toward her. Sasha stepped away and circled to Jackie’s side, both to be visible to the giant woman and on the outside chance that those tits might reach the ground, crushing her.

What a glorious way to go… Sasha shook the thought away, watching a face as tall as her entire body loom toward her.

Jackie grinned. “There you are! You’re so far away, let me help you…”

Her girlish giggle created more tremors that Sasha felt in her core. Then a hand reached down. Nearly three feet from wrist to fingertip, Jackie’s hand cupped Sasha’s bottom, forcing her to sit as a forearm-sized thumb pressed gently into her pelvis. A thrill shot through her from the pressure, and she clenched her thighs to keep from coming before she put two and two together.

“Wait, Jackie nooooooooo!”

Sasha’s hair whipped as vertigo sent her guts dropping to her toes. In seconds, she was face to face with Jackie, over thirty feet in the air, still gripped in the blonde’s hand. She clutched the giant thumb, white-knuckled like a roller coaster bar, its gentle pressure making her body tense and pulse with need.

Sasha’s world spun again, and she found herself deposited on the slope of one gigantic breast. She’d used her free arm to heft them upward. “That’s better,” she boomed.

Sasha’s voice came out tremulous and weak. “Jackie, I…”

“Oh, Sasha, isn’t it great! I wanted bigger boobs, and now I have the biggest boobs ever! Thank you so much!”

The fleshy platform under Sasha’s feet heaved, billowing upward as Jackie’s face drew closer. She fell on her ass, her hands scrambling for purchase on the smooth expanse of skin. Jackie planted a kiss that covered Sasha’s entire face.

Sasha had half a second to appreciate the touch before the vertigo returned. The big idiot lifted her head, dropping her tits as she looked around the city—no doubt searching for her next meal. Unfortunately, this sent Sasha sliding down the curve of her titanic tits. In her panicked flailing, she caught a few handfuls of Jackie’s ponytail as it brushed past. Summoning every ounce of her meager athleticism, Sasha climbed over Jackie’s clavicle to sit on her shoulder.

“Oh, whoops. Sorry about that…”

Sasha panted and shook, gripping the short hairs at Jackie’s nape. “Jackie… don’t you think… you’ve had enough?”

She felt Jackie’s rumbling stomach vibrate through her bottom.

“Maybe just… a little more…”

A gentle wind brushed against Sasha as Jackie started walking. She heard the pavement cracking even if she couldn’t see it past literal acres of cleavage.

Then she saw where they were heading.

Toward a pair of pale mounds that Sasha knew were taller than even Jackie’s overgrown form.

A pair of tits colloquially known as “Mount Madison.”

And the massive industrial complex of food production—built to keep them growing ever larger.

A ball of lead formed in Sasha’s gut. Her thighs quivered. “Oh, no…”
