FAT FICTION | Chapter 11 - The Path to Bigger Things (Patreon)

Emily Carter and Jess Moreno had a ritual.

Every morning before classes, the two cross-country teammates met at the motorway diner near Halden University’s athletic center at six sharp. They ate a healthy breakfast of yogurt and cereal, stretched beneath the flickering parking lot lights, and vanished into the waking countryside together.

They were opposites in almost every way.

Emily was blonde, reserved, and razor disciplined. Tall and narrow-hipped, she treated every mile like a challenge to conquer. Jess, meanwhile, was brunette, loud, impulsive, and stronger built despite being just as lean. She ran because she loved the feeling of freedom.

But together, they worked perfectly.

That Friday evening, after a brutal endurance workout, the girls stood beneath the steaming showers in the women’s locker room, exhausted and half delirious.

Water cascaded over their athletic bodies.

Emily tipped her head back into the spray with a groan. “Coach is trying to kill us.”

Jess laughed, slicking wet hair behind her shoulders. “You say that every week.”

“Because every week he adds another five miles.”

The locker room was empty except for them. Steam curled around the tiled walls while the sounds of distant basketball practice echoed faintly through the building.

Jess leaned against the wall. “Let’s skip the track tomorrow.”

Emily opened one eye suspiciously. “Skip training?”

“No,” Jess said. “Adventure run.”

That got Emily’s attention.

“There’s supposedly an old hiking trail past Blackthorn Woods. Waterfalls and cliffs and all that dramatic fantasy novel stuff.”

Emily snorted. “You made that up.”

“I absolutely did not.”

Jess grinned wickedly. “C’mon. Twenty miles. No coaches. No watches. Just us.”

Emily hesitated.

Then smiled.

“Fine.”

The next morning arrived cold and grey.

The girls ran side-by-side along empty country roads before turning onto a narrow dirt trail swallowed by dense woods. Fallen leaves crunched beneath their running shoes while sunlight filtered through the enormous trees overhead.

At first, it was exhilarating. Nothing but them and the wild nature that grew all about them. The peace that came with the rhythmic sound of breathing and footsteps.

But after nearly two hours, Emily slowed.

“Jess…”

“Yeah?”

“I don’t think this is the trail anymore.”

Jess stopped beside her, turning slowly. The woods had changed. The trees here were massive now, ancient things covered in emerald moss. The air felt strangely warm despite the autumn chill. Birds had gone silent.

Then they heard water. A distant roar. The girls exchanged a look before jogging toward the sound. And froze. The clearing looked unreal.

A crystal-blue lagoon stretched before them, fed by a towering waterfall cascading down smooth black stone. Sunlight pierced the canopy above in glowing shafts that made the entire pool shimmer like liquid glass.

“Oh my God,” Jess whispered.

Emily could only stare.

The place felt untouched. Sacred and magical.

Jess grinned suddenly. “We are absolutely swimming in that.”

Emily laughed. “We don’t have towels.”

“Coward.”

Within moments Jess had peeled off her damp running shirt and shorts, tossing them onto a rock before kicking away her shoes. 

Emily rolled her eyes.

Then followed.

The two girls dove into the lagoon wearing nothing but a sports bra and panties each, shrieking laughter.

The water was perfect.

Not cold like a mountain stream should have been, but cool and silky against their skin. Every ache vanished instantly. Emily surfaced feeling lighter than air.

Jess floated nearby on her back. “Okay,” she murmured, “this is magical.”

Emily splashed her. “Literal fairytale nonsense.”

But secretly she agreed.

The exhaustion from weeks of training had evaporated completely. Her muscles felt loose and powerful. Her skin tingled pleasantly.

Then Jess pointed toward the waterfall.

“Look.”

Behind the crashing curtain of water was an opening in the cliffside.

A cave.

Steam drifted from inside. Curiosity overcame caution. The girls waded through the lagoon and pushed past the roaring waterfall into the hidden cavern beyond.

Warm mist enveloped them instantly.

Inside was a natural stone chamber glowing faintly with pale blue mineral light. Pools of steaming water bubbled beneath smooth rock ledges. The air was intoxicating.

Emily inhaled deeply. It smelled strangely sweet. It felt oddly comforting.

Jess sat on one of the submerged rocks with a blissful groan. “Ohhhh my God.”

Emily laughed and joined her.

The heat soaked into their bodies.

At first, it simply felt relaxing.

Then… oddly heavy.

The steam noticeably thickened around them like something alive.

Emily wiped moisture from her face and took an uneasy breath, only to feel the heat sink deeper into her body. It wasn’t ordinary warmth. It penetrated beneath her skin in slow, heavy waves that made her limbs feel loose and highly sensitive.

Jess shifted beside her on the stone with a soft gasp.

“Emily…”

Emily turned. She froze. Her friend was staring downwards.

Jess’s chest was swelling.

Not subtly.

The curves of her small athletic breasts were visibly pushing outward by the second, her tits were rounding fuller and heavier until soft undercurves pressed against her ribcage. Tiny droplets of steam clung to her skin while her nipples hardened sharply in the heat.

“What the hell...” her words faltered into a moan.

Jess grabbed at herself instinctively, but that only emphasised the change. Her hands sank into her new gigantic breasts, that hadn’t existed moments ago.

Then Emily felt it too.

A deep tingling low in her hips.

A strange pulsing wave of euphoria came over her. One she couldn’t understand. Her thighs suddenly pressed tighter together. She realised she hadn’t moved...

...they’d grown thicker.

Thick enough to touch all by themselves. 

She stumbled upright with a startled gasp as the lean muscle in her legs evaporated into softeness rapidly.

Smoothing themselves into thick, lushcous rolls.

Her inner thighs spread wider and wider, fat beginning to rub and then crease, with every shaky movement.

“Oh God… what's happening to us?”

The steam curled around her waist.

Her flat stomach quivered.

Then began popped outward, a dramatic and rapid movement. It spread like rising dough.

Emily grabbed at her belly in panic, feeling chubby rolls gather beneath her fingers.

Jess stared ,, half-dazed. Half... well, her mind wasn't prepared to admit there was a certain thrill to all of this.

“Your stomach…”

Emily looked down just in time to see it expand further, a soft layer spilling over her hips.

Meanwhile Jess’s transformation accelerated.

Her hips widened audibly with soft creaking pops, spreading against the stone seat while thick fat poured over her lap. Her once-powerful runner’s thighs ballooned, dimples and cellulite forming as they pressed together heavily.

“Emily, we're becoming… fff...fat.”

Her voice came out breathless.

Because it wasn’t over yet.

Jess’s stomach softened, spilling outward into a large curve while her waist thickened and folded to create new fat rolls on eother side. Her breasts continued swelling with impossible fullness until they bounced heavily with every frantic breath.

The steam seemed to reward panic… or was it something else? 

Every gasp. 

Every movement.

More. It needed more.

Emily backed away toward the cave wall, but her balance felt off now. Her arse had begun swelling, growing heavy and round and shaking violently. Enough to tug her backward with each step. She collided with the stone wall and moaned softly as the impact made her expanding body wobble visibly all over.

“Fuck! No no no…”

Her sports-trained body was disappearing beneath layer after layer after layer of fattened softness.

Her hips spread wider.

Her thighs grew thicker.

Her shoulders grew soft and broad and matched her pillowy arms.

Her breasts surged heavily outward until she needed both arms to support them instinctively.

Jess let out a startled laugh that quickly became a gasp as her belly dropped lower, no longer merely soft but undeniably fat now. It hung with noticeable weight from her middle while fresh rolls formed along her sides.

The steam continued to wrap itself around both women greedily.

Emily’s stomach lurched outward again.

A thick fold burst forward and spread over the tops of her thighs.

She stared in horrified fascination as her body abandoned every trace of athleticism. Her arms softened rapidly, upper flesh jiggling when she lifted them. Her face felt warm and soft as her cheeks filled visibly, rounding into a moon-shape while the start of a second chin began forming beneath her jaw.

Jess looked even bigger now.

Much bigger.

Her thighs spread across the stone seat while her hips had become obscenely broad, forcing her legs apart. Her breasts rested against the top of her swollen stomach, both bouncing softly whenever she shifted.

And she was still growing.

“Emily…” she whispered weakly.

The blonde looked over.

Jess’s belly suddenly lurched outward another few inches in one smooth motion.

Both girls gasped. But there was more than fear in their tone. There was curiosity too.

The weight of it settled heavily into her lap.

“Holy fuck…”

Emily barely recognised her own voice anymore. It had gone softer somehow, breathier beneath the overwhelming heat.

Then her own body answered.

Her arse ballooned behind her, thick blubber pushing outward until her lower back arched automatically to compensate. The movement thrust her growing chest forward while her stomach spilled farther over her hips.

She looked down helplessly as her thighs swallowed the gap between her legs entirely.

Every inch of her jiggled now.

The steam made their transformed bodies feel hypersensitive. Every brush of skin sent warmth rippling through them. Their massive thighs slid against each other slickly, while sweat and condensation gleamed across their expanding curves.

Jess tried standing.

Immediately her heavy belly dragged her forward.

“Oh my God,” she breathed, grabbing underneath it.

The gesture made both girls freeze.

Because her stomach was big enough to hold.

As if the steam heard their thoughts, Emily’s eyes widened as her own middle suddenly dropped lower too, soft fat pooling into her lap while fresh fullness spread along her sides and back.

The cave groaned softly around them.

The transformation reached another sudden crescendo.

Their bodies surged outward together.

Breasts swelling round and pendulous.

Hips spreading wider than doorframes.

Bellies ballooning into vast rounded domes.

Thighs engulfing the stone beneath them.

Within moments the two former athletes had become enormously obese women, their old lean physiques buried beneath mountains of abundant feminine fat.

Jess’s stomach now rested heavily atop colossal thighs, that folded into rolls at her knees. Below, huge calves gave way to cankles and pody feet. Her breasts sagged richly against her belly's upper curve.

Emily’s hips had become unbelievably wide; magnificent. Her huge arse and enromous double belly making movement nearly impossible.

Both women panted in the heavy steam.

Sweaty.

Massive.

Overwhelmed by the sheer physicality of their transformed bodies.

Then the waterfall entrance shimmered.

And the world ripped away beneath them.

—-----

Emily felt cool tiles beneath her feet.

She blinked.

Fluorescent lights buzzed overhead.

Lockers lined the walls.

They were back in the team shower room.

Emily froze.

Jess stood beside her, equally stunned.

Both girls were naked.

And undeniably obese.

Their immense bodies loomed large in the middle of the locker room, swollen, stuffed and drowning in layers of soft, sexy fatness. Gigantic breasts hung heavily from their chests, resting against huge bellies that pushed proudly outward before spilling over the waistline of their thick thighs. Their hips poured outward enormously to either side, forcing their legs apart beneath the sheer weight of their lower bodies, while every shift and breath sent visible ripples through every roll of fat that coated what had once been lean athletic frames… long lost, several hundred pounds ago. 

Emily stared at her own hands, plump, but tiny against the immensity of her body.

“What…”

The locker room door swung open.
