Sasha stood atop the apex of Jackie’s mountainous right breast. Her shoes had slipped off at some point in her rapid journey from the ground, and her socks sank gently into the plump skin under her feet. Her knees already shaky, Sasha could only stay upright for a few staccato heartbeats before she tipped onto her hands and knees. That was fine. She didn’t need to be standing for what happened next.

Large as it was, Jackie’s nipple was still smaller than Sasha’s fist and appeared soft enough for what Jackie evidently intended for her to do with it. Sasha flared her lab coat and skirt, shuffling on her knees to straddle the enormous nub. Far below her, Jackie grabbed the feeding tube that was now well within reach and slid it between her lips, still shiny from the entire truck fleet’s worth of food she’d already eaten.

Ulp ulp ulp

Bwooommmmm

A rhythmic suckling and slurping filled the air, and a gentle thrum pulsed under Sasha’s knees. She felt the flesh beneath her expanding, increasing. As she slid Jackie’s nipple into her wet and waiting slit, Sasha imagined the contents of that massive hose flowing into the titanic woman beneath her. A river of nutrient sludge, pumping into Jackie as quickly as she could chug it down. Breaking down with incredible speed into proteins, carbs, and sugars. Pouring through her body in torrents to collect in her gargantuan mammary glands. Billions of cells, absorbing those nutrients, growing fatter and rounder until they split into pairs that in turn grew and swelled, splitting into their own pairs. Over and over, impossibly rapid, until Sasha thought she could feel herself being lifted upward, riding a gigantic water balloon attached to a garden hose, swelling higher and higher. That quiet voice in the back of Sasha’s head—the rational one—whispered that the metaphor wasn’t as ridiculous as she gave it credit for, considering…

Jackie’s nipple filled Sasha to capacity, and the clearing echoed with the giant woman’s moans. In the distance below Sasha’s perch, Jackie’s legs kicked, and her hips rocked. She was likely causing smaller versions of the quakes Madison sometimes produced, but the shockwaves were absorbed by her enormous breasts long before they reached Sasha. Jackie’s massive peak stiffened inside Sasha, stretching and swelling until it seemed it might split her in two. Sasha’s world narrowed to pure sensation as she came, bobbing on Jackie like a lifeboat on an undulating sea. Time slipped away, and her juices trickled down the impossible slopes as they slowly swelled with thousands of gallons of sweet, rich sludge pouring down Jackie’s throat.

Sasha thrust herself onto Jackie again and again. She pressed with her palms, groping the minuscule fraction of Jackie’s tits that would fit in her grasp. Her stomach gently churned as she swayed and bobbed, rising and falling, but mostly rising. Her head fell limp between her shoulders as she came, and came, and came.

Whuppa whuppa whuppa

When Sasha’s senses cleared—the world around her returning to focus—the first thing she noticed was the thrum of helicopter blades. The second was Jackie’s stomach, rising like a foothill in the shadow of her mountainous glands. Sasha crawled off of her crush-turned-natural-disaster, feeling cold and empty the moment Jackie’s engorged nipple slid free with a wet pop. She turned on quavering knees and crawled forward to find the blonde’s face. Jackie’s head was much farther away than it had been when she dropped Sasha on her peak. Sasha knew she couldn’t estimate accurately from her current perspective, but she guessed Jackie’s tits had more than doubled in size since she started drinking from the tube. The tube Jackie still held between her perfect lips, arms folded behind her head as she guzzled in oblivious bliss.

“Jackie!”

Jackie’s eyes fluttered open. “Hmm?” She asked around the nozzle.

“It’s stopped working!”

Finally, Jackie stopped drinking, reaching around her personal mountain range. Sasha watched Jackie’s left gland rise and shift against the one she knelt on, the blonde’s eyes widening with shock as she palmed her swollen middle with one giant hand.

“More importantly, we’re in danger!” Sasha shouted.

In another wave of vertigo, Jackie wrapped an enormous hand around Sasha as she sat up. From her elevated perch on Jackie’s minivan-sized palm, Sasha saw a small army of tanks, trucks, and helicopters advancing on their field.

“What’s happening?” Jackie whined, still sadly poking at her bloated tummy with her free hand.

“It must have been a ploy!” Sasha shouted.

“A… ploy?”

Jackie’s hand moved again, and Sasha clung to a thumb larger than her entire body as she was lifted nearer to Jackie’s face.

“It was a distraction,” Sasha said. “Lure you here with food while they waited for reinforcements.”

It wasn’t a great plan, Sasha mused. They’d been here for hours, and Jackie had spent every minute gorging herself. She’d grown to at least a hundred feet tall. If those war machines pissed her off, dozens, if not hundreds, of people could die.

The towering blonde didn’t look angry, however. Her eyes glistened with the beginnings of tears that could hold a liter of saline in a single drop. “But why? I thought Madison was just being nice to me…”

Sasha stroked a tree-trunk thumb with her palm. “I don’t know if you’ve noticed, babe, but you’ve made kind of a mess today.”

“I didn’t mean to! I just wanted bigger boobs, and I was so hungry…”

“Shh, I know you were, it’s okay.” Sasha didn’t know what that small army’s rules of engagement were, but she had to keep Jackie calm.

Jackie poked at her stomach again. “It’s stopped working now anyway. I don’t even want any more food…”

Sasha looked across the valley to the flesh mountains dominating the horizon. Madison still dwarfed Jackie, but she had no doubt the former secretary could cause some real damage if she wanted to. “I don’t think…”

“Hmm?”

Sasha couldn’t stop her lips from spreading into a grin. “I don’t think there’s room in this city for two giant boob monsters, do you?”

“Hey! I’m not a monster!” Jackie was smiling now, too.

“You do have giant boobs though…”

Jackie looked past Sasha to the hectares of cleavage below. She couldn’t be certain, but Sasha suspected they were big enough to rest in Jackie’s lap. Jackie’s giggle was startling with her gale-force voice. “I guess maybe I did overdo it… just a bit.”

“Just a bit.”

The tanks rumbled closer.

“What should we do?” Jackie asked. “Maybe we can talk to them, work something out?”

Thoom

A soft thud in the distance preceded a gentle whistling that grew louder.

CRACK

SHHHHHH

A shell exploded a dozen meters from Jackie’s head, creating a small cloud of grey-white smoke that drifted lazily in the breeze.

“I don’t think they want to negotiate,” Sasha said.

“What do we do!?”

For all the challenges of dealing with a giant, hungry Jackie, the last thing Sasha wanted was a Hulk Smash Jackie, or the guilt and trauma that would inevitably follow.

“We need to run.”

“Run? How? Where?”

BOOF

A geyser of dirt and stones erupted a few meters from Jackie’s foot. Still not close enough to harm her, but closer than the smoke shell.

“Anywhere but here, come on, Jackie, go!”

Sasha’s stomach dropped into her feet as Jackie stood, then set her on top of her head. “Hang on!” Jackie boomed.

Sasha clung to fistfuls of blonde hair as Jackie strode toward the harbor. The highest of Madison’s factories and warehouses only reached Jackie’s waist. Her steps were slow and staggering, her arms overflowing with a pair of tits like blue whales. She left craters in the concrete as she crossed the docks and stepped into the harbor. Her legs disappeared to the knees in murky water. Boats and barges heaved and listed in the wake of her slow, wading steps.

Within moments, Jackie was waist-deep in the Atlantic. Sasha turned to watch the city recede behind them. The trucks and tanks had no chance of matching their pace, and when the helicopters reached the harbor, they hovered there at the coastline. When Jackie waded into deep enough water that her cumbersome glands began to bob, relieving her of their weight, she leaned forward into an ironic breaststroke.

Sasha watched the rise of Jackie’s wake flowing behind them, wondering how much damage it would cause along the shoreline.

“Are they still following us?” Jackie asked.

Sasha squinted toward the shrinking harbor, but could not see the dark shapes of helicopters or ships pursuing them. Perhaps they were unwilling or unable to follow them into international waters.

“I don’t think so.”

Jackie’s wide strokes relaxed, and they drifted toward the southeast. Sasha hoped they could find an uninhabited island where Jackie could rest and digest at a normal pace. And also find food. Even without a chemically-accelerated metabolism, it would take a lot to keep Jackie fed. She wondered how hard it was to learn to fish. As they floated lazily into the vast blue horizon, Sasha hoped her boobzilla girlfriend wouldn’t get a cramp from swimming so soon after eating.
