Bounty Hunter Ass Expansion Compilation

The mission was simple… until the target fought back with a weapon she was not prepared for.

This new Swelling Studios compilation follows a fierce bounty hunter as her confident, no-nonsense attitude slowly falls apart while her body starts expanding out of control. Every scene pushes the growth bigger, heavier, and more ridiculous — from subtle swelling to full-blown oversized chaos.

Expect tight outfits under pressure, embarrassed reactions, heavy movement, and that perfect mix of action, sci-fi, and Swelling Studios expansion fantasy.

Enjoy the hunt… and the growth.

The Fourth of July Blow-Up (Trailer)

Mia was enjoying the Fourth of July party — string lights glowing, grill smoking, red cup in hand, laughing with a guy near the picnic table. She wore a tight patriotic crop top with red and white horizontal stripes across the chest and a blue star band along the bottom, cropped high over her denim shorts.

Near the unlit fireworks, a novelty smoke canister labeled “Grand Finale Smoke Burst” had tipped over. It didn’t explode. It just started hissing, thick red, white, and blue smoke pouring out and drifting low across the grass.

Most people didn’t notice. Mia didn’t either — until the colorful cloud curled up behind her and she breathed in a lungful.

She coughed, waving it away. Then she felt the warmth bloom in her chest.

Her top suddenly felt tighter. She glanced down and frowned, tugging at the hem. The stripes looked straighter. Her breasts felt heavier. She tried to ignore it and keep talking, but the pressure kept building.

Another wave of smoke drifted past.

Her breasts surged outward in one smooth rush, pushing hard against the crop top. The red and white stripes stretched wide across her growing curves. The blue star band rode up, exposing the first pale curve of underboob. Her nipples stiffened visibly through the thin fabric.

Mia’s eyes widened. She stepped back toward the picnic table, angling her body away from the guy, one hand pressing against her chest. “I— I need a second.”

The growth didn’t stop.

The smoke kept coming. Her breasts swelled larger with every second, the crop top straining tight. Seams creaked. The weight pulled her forward. She braced both hands on the picnic table, leaning over it as her chest hung heavier and rounder beneath her. The stripes were warped and distorted across the massive, taut shapes.

People were staring now. Conversations died. Someone pointed at the hissing canister, then at her.

Mia’s face burned. She tried to cover herself, but there was too much of her. The crop top was stretched obscenely thin, underboob spilling out, every breath making her enormous breasts rise and fall heavily.

Another powerful surge hit. Her breasts ballooned even larger — huge, hyper-full, and impossibly round. The top looked ready to tear. She gasped, mortified, as the entire party watched.

She couldn’t stay.

Still hunched from the weight, Mia turned and tried to hurry toward the house. Her massive breasts bounced and swayed with every step, the ruined crop top riding higher. The colorful smoke followed her.

Behind her, the Grand Finale Smoke Burst canister kept hissing on the patio.

The real fireworks never started.

She had become the grand finale.

SeraphimLockhart Collection 🫐

SeraphimLockhart is one of my VIP subs, and they requested some blueberry morphs of their OC. They were also cool enough to give me permission to post them here.

I love doing stuff like this. Bringing someone’s OC into the Swelling Studios style is always a fun challenge, especially when they trust me with their character.

So if anyone else has a request like this, let me know 👀

Too Much Flavor Out Now!

Violet Beauregarde didn’t win her golden ticket by luck.

She earned it.

After taking first place in her college gum-chewing contest, Violet walked into Wonka’s factory with one goal in mind. She wasn’t there to admire the candy. She wasn’t there to be amazed by the tour. She was there to win the grand prize: a lifetime supply of chocolate.

And nothing was going to get in her way.

But inside the Inventing Room, Violet discovers something even bigger than the prize.

Wonka’s newest creation.

A three-course dinner in a single piece of chewing gum.

Everyone is told it isn’t ready. Everyone is warned not to touch it.

But Violet has never been good at backing down.

Determined to be the first person in history to chew an entire meal, she snatches the gum from Wonka’s hand and starts chewing before anyone can stop her.

At first, she thinks she’s won.

Tomato soup.

Roast beef and baked potato.

Blueberry pie and ice cream.

Then the flavor becomes too strong.

The gum keeps going.

And Violet starts to change.

Her pride turns to panic as the dessert course fills her with juice, swelling her bigger and bigger until she becomes too round, too heavy, and too helpless to move.

Now the tour has stopped.

Her father is horrified.

Wonka has only one solution.

Call in the Oompa Loompas.

As they push, pull, and struggle to move her, Violet learns too late that some contests can’t be won by chewing harder.

And some flavors are more than anyone can handle.

This is the story of a girl who wanted to make history…

and became the biggest problem in the factory.

Too Much Flavor.

Coming soon from Swelling Studios.

The Checkup

She went to the doctor because the swelling had not stopped all morning.

At first, she had tried to ignore it. She told herself it was just soreness, maybe a reaction to something, maybe her body playing tricks on her. But every time she looked down, her chest looked fuller than it had a few minutes before. Her top kept pulling tighter. Her posture kept changing. The weight kept building.

By the time she reached the exam room, she was trying hard to act normal.

The doctor asked her to stand sideways for a better look. She placed one hand on her lower back, partly for support and partly because the new weight was making her lean forward. She gave a nervous little smile, like she was embarrassed to even explain it.

“It started small,” she said. “Just pressure. Then it got heavier. And now… it won’t stop.”

The doctor began checking her over, asking routine questions, trying to stay professional. But even while they talked, her top stretched tighter across her chest. The fabric smoothed out, pulling across the swelling curve like it was fighting to keep up.

She noticed the doctor pause.

Then she felt it.

A deep, warm pressure bloomed inside her chest.

Her breath caught. Her hand pressed harder against her back. She looked down just as another growth spurt began.

Right there in the exam room, in front of the doctor, her chest started swelling again.

It was slow at first, a steady outward push that made the fabric strain. Then it became impossible to pretend nothing was happening. Her body shifted under the weight. Her shoulders pulled back. Her lips parted as she tried to stay still, embarrassed and overwhelmed, but unable to stop watching herself grow.

The doctor stepped closer, stunned but focused.

“Stay still,” the doctor said. “I need to see how fast it’s happening.”

She nodded, but her face flushed. The pressure was frightening, but not painful. It was tight, heavy, and strangely intense, like her body was reacting to being watched. The more attention the doctor gave her, the more aware she became of every inch of growth.

Her chest pushed farther out.

The room felt too quiet.

She tried to laugh it off, but her voice came out breathy.

“This is so embarrassing…”

The doctor kept taking notes, but even they seemed surprised now. The swelling was no longer subtle. Her top was stretched to its limit, and she had to lean back slightly just to balance herself.

Another pulse hit.

She gasped and grabbed her lower back again.

The doctor asked if it hurt.

She shook her head quickly, eyes wide, still staring down at herself.

“No… it’s just… it feels like it’s still filling.”

The growth slowed for a moment, leaving her standing there, huge, heavy, and stunned in the bright clean office. She looked completely caught between panic and reluctant fascination, as if part of her wanted help and another part could not believe what her body was doing.

Then her expression changed.

She felt another wave starting.

Her eyes lifted toward the doctor, nervous and breathless.

“Doctor…” she whispered, “it’s happening again.”

Pre-Workout Gone Wrong

She was just trying to get a quick selfie after her workout when the new pre-workout supplement she’d taken started to hit her much harder than expected.

At first it was just warmth spreading through her chest. Then the heat turned into a deep, tight pressure. Her breasts began to swell, growing heavier and rounder with every breath. The black sports bra that had fit her fine minutes earlier was suddenly struggling, the fabric stretching tight across her expanding chest.

She felt the weight increasing fast, pulling the bra down as her tits grew fuller and more sensitive. The straps dug into her shoulders while the band tightened around her ribcage. Sweat broke out across her skin as the growth continued, the once comfortable sports bra now stretched thin and shiny over her rapidly ballooning breasts.

Her breathing grew shaky, soft gasps escaping her lips as she watched them swell bigger right in front of her. The fabric creaked with every inch they gained, the material straining hard to contain the sheer size and weight. Her nipples pressed stiffly against the stretched fabric, every brush of the bra sending sparks through her.

By the time the growth finally slowed, her breasts were massively oversized — heavy, flushed, and barely contained. The sports bra looked ready to snap, stretched so tight it dug deep into her soft flesh. She stood there in the middle of the gym, phone still in her hand, chest heaving as she stared down at what she’d become. Too big. Too obvious. And far too sensitive to ignore.

Reach Grab

Mia was already struggling to reach the top shelf when Jade walked into the kitchen.

Her body had changed so much in the last few days that even simple things felt different now. Her huge breasts pressed against the counter and her massive ass stuck out far behind her, making her stretch and arch just to grab what she needed.

Jade stopped in the doorway, eyes locked on that enormous, soft ass barely covered by the tight gray panties. She didn’t say anything at first. She just stepped up behind Mia, placed both hands on those heavy cheeks, and squeezed.

Mia glanced back over her shoulder, a small smile on her lips.

“Couldn’t help yourself?” she teased, voice a little breathy.

Jade’s fingers sank deeper into the plush flesh, kneading slowly. “You’re reaching like that on purpose,” she murmured, giving another firm squeeze. “Look at this… it’s ridiculous how big you’ve gotten.”

Mia let out a soft laugh that turned into a quiet gasp when Jade’s hands spread her cheeks apart slightly. “I really was just trying to get the cereal…”

“Sure you were,” Jade said, voice low as she kept groping, thumbs pressing into the soft skin. “Keep reaching. I’m not done checking yet.”

The Overdose Check

Emma had only meant to help. One little growth pill for her shy roommate. “You’ll wake up with a nice surprise,” she’d said.

She had no idea how strong it was.

When she walked in the next morning, Sarah was on the bed in nothing but pink panties, her chest now two gigantic, heavy, vein-covered breasts that looked almost obscene. They were swollen, pendulous, and still faintly throbbing.

“Emma… they won’t stop,” Sarah whispered, cheeks burning as she looked up.

Emma’s shock only lasted a second. She climbed onto the bed and grabbed one massive tit with both hands, sinking her fingers deep into the warm, soft flesh. The weight was shocking. She squeezed, lifted, and watched the heavy breast overflow her palms while the veins stood out even more.

Sarah gasped, back arching. “They’re so sensitive… fuck—”

Emma’s voice came out low and rough. “I’m just checking what I did to you. God, they’re huge. And still getting bigger, aren’t they?” She rolled a thick nipple between her fingers. “You love being this swollen and helpless, don’t you?”

You're Bigger than Expected

She had been expecting something impressive. She had not been expecting that.

Her eyes dropped, then immediately widened. Both hands flew to her mouth as a nervous laugh escaped her. For a few seconds she couldn't even find the words. Every time she thought she had something to say, she looked down again and completely lost her train of thought.

"Okay..." she whispered, trying—and failing—to hide her smile. "That is... a lot more than I was expecting."

She shook her head in disbelief, cheeks growing warmer by the second. "I don't even know what to say right now."

Waking up my Busty Girlfriend

She had fallen asleep halfway through the movie.

Now she was completely sprawled across the couch, breathing softly, absolutely refusing to wake up. The credits had rolled twenty minutes ago, but she hadn't moved an inch.

You tried calling her name.

Nothing.

You tried nudging her shoulder.

Still nothing.

Finally, you gave her a gentle poke and watched her make a sleepy little face without opening her eyes.

"Five more minutes," she mumbled.

A few seconds later, one eye cracked open. She looked up at you, completely disoriented.

"Did I fall asleep again?"

The answer was obvious.

She smiled lazily, stretched, and immediately curled back into the couch cushions.

"Okay," she said, already drifting off again. "This time wake me up in five minutes for real."

Within seconds, she was asleep once more.

Thicc Girl in the Library

The library was almost empty.

Most people stayed on the lower floors, leaving the quiet corner near the old bookshelves completely deserted. Sunlight poured through the tall windows, painting warm rectangles across the floor. You had come up there expecting to study for an hour.

Instead, you found your girlfriend waiting.

She leaned against the window with a mischievous smile, clearly pleased with herself for getting there first.

"I knew you'd find me eventually," she whispered.

When you asked why she had picked the most isolated part of the building, she laughed and glanced around at the empty shelves.

"Because nobody ever comes up here."

Her fingers found yours as she stepped closer.

The noise of the campus faded away until it felt like the two of you were the only people in the building. She rested her head against your shoulder, smiling softly.

"I wasn't really in the mood to study today," she admitted.

Outside, students hurried across campus while sunlight sparkled through the glass. Inside, surrounded by old books and perfect silence, she looked completely content.

"Let's stay here a little longer," she said. "Just us."

Life with Macromastia Bayonette Cosplay

"How far out is the Uber?" she asked, adjusting her glasses. "Still two minutes?" A nervous laugh escaped her. "I swear every time it says two minutes, it's like five." She shifted awkwardly on the sidewalk, trying not to draw attention to herself, but it was impossible. Her Bayonetta costume had always been ambitious, and her already enormous chest made it even harder to blend into the crowd. Every passing glance from strangers only made her more self-conscious.

"Hey, at least we aren't late," she said, trying to fill the silence before immediately cringing. "Sorry... I'm so awkward." Her cheeks warmed as she looked away. The costume, the convention, the waiting—it wasn't what made her nervous. It was standing there next to the person she had a crush on, hoping they thought her cosplay was cool and not noticing how hard she was trying to act normal while carrying around a chest that seemed determined to steal all the attention in the room.

The Room at the End of the Hall

You were told not to go upstairs.

That was the only rule the host gave you when you entered the old house: enjoy the music, enjoy the wine, enjoy the strange little party downstairs — but do not open the black door at the end of the upper hall.

So, naturally, that was the door you found yourself standing in front of.

The house had been leading you there all night. A glimpse of blonde hair in a mirror. A soft sliding sound behind the walls. Candles flickering to life as you passed, one after another, like something unseen was guiding your steps.

When you finally touched the handle, the door opened before you could turn it.

Inside was a room lit only by candles. Dark walls. Old rugs. Heavy perfume in the air. And in the center of it all, coiled comfortably across the floor, was her.

A snake girl.

Her long green tail circled the room in slow, powerful loops, glossy scales catching the candlelight. She sat perfectly still, watching you with bright, knowing eyes, like she had been waiting for this exact moment. Behind her, the serpent head lifted slightly, curious but calm.

You froze in the doorway.

She smiled.

“So you finally found me.”

Your mouth went dry. “I didn’t mean to come in here.”

“No,” she said softly, tilting her head. “But you wanted to.”

The door clicked shut behind you.

Her tail shifted with a slow, heavy scrape against the floor, not trapping you exactly — just reminding you how easily she could. She rested one hand on the thick coil beside her, studying you like a secret she had already decided to keep.

“I’ve been watching you all evening,” she said. “The way you ignored every warning. The way you kept looking for something more interesting than the party downstairs.”

She leaned forward slightly, her smile becoming warmer.

“And then there you were.”

The candles flickered.

“You’re not in trouble,” she purred. “Not unless you try to leave too quickly.”

You looked back at the door, then at the huge green coils surrounding the room, then finally at her.

She laughed softly.

“Relax,” she said. “I only bite when I’m bored.”

Her tail shifted again, opening just enough space in front of her.

“Come closer,” she whispered. “I want a better look at what wandered into my room.”

The Worst Possible Time

Ilulu had been managing the random growth spurts for weeks.

They never came on a schedule. Sometimes it was just a little pressure, a little extra weight, enough to make her grumble and disappear for a few minutes until it passed. Other times it was worse — a hot swelling ache deep in her flame sacs that meant she needed to sit down, breathe, and hope nobody noticed how much fuller she looked when she came back.

Today, of course, it happened at work.

She was behind the counter sorting candy into jars, trying to focus on something simple, when the first pulse hit. It made her pause mid-motion, fingers still buried in the sweets as she looked down at herself. A familiar heaviness was already building under her shirt.

“No, no, not now...” she muttered.

She tried to ignore it. Kept working. Kept her head down. Maybe if she didn’t think about it, it would stay small.

But the heat in her chest only got stronger.

Her flame sacs began to swell again, slowly at first, stretching the front of her shirt and making her shift awkwardly behind the counter. She could already feel the extra weight settling against her torso, fuller with every breath. The worst part was knowing exactly what came next — once the swelling started, it never stopped at a “reasonable” size.

By the time she looked up again, she was blushing.

The pressure had become impossible to hide. Her shirt was riding tighter and tighter, her posture changing as the weight pushed outward, and she could feel each new surge making them grow heavier, rounder, more obvious. She was supposed to be helping customers, not standing there praying nobody walked in at the exact wrong moment.

Then the next spurt hit hard.

Her flame sacs swelled dramatically, ballooning outward until they dominated the entire space in front of her. The counter was suddenly the only thing keeping her steady. She let out a soft, frustrated breath, but there was no real panic in it — only embarrassment, and that familiar helpless acceptance. This had happened enough times that she knew struggling wouldn’t stop it.

All she could do was endure it.

By the end, she was left standing behind the candy counter with an awkward little smile, face warm, chest massive and impossible to miss, the workday effectively over whether she liked it or not.

Random growth spurts were bad enough.

Having one in the middle of a shift?

That was definitely the worst possible time.

Morning Test Gone Wrong

She only meant to film a quick update.

Lying across the bed in the morning light, she smiled at the camera and flashed a peace sign. The formula had worked overnight — her breasts were already massive, glossy, and so heavy they pinned her to the mattress. She laughed softly. “See? All done.”

Sunlight slid across her chest.

A deep throb answered. Both breasts began swelling again, skin stretching tighter with every second. Her nipples thickened and started leaking slow drips of milk. The weight increased fast — the bed creaked, sheets pulled tight, and her arms were pushed outward as the growing mass forced them aside.

She gasped, trying to hold one back, but it only swelled harder around her fingers, rounder and heavier. Pleasure hit her hard. Her thighs squeezed together as the expansion made her wet and desperate. One breast surged ahead, ballooning massively, veins standing out under the glossy skin. It grew until it filled most of the frame, pushing right toward the camera, her face visible only in the corner — eyes wide, mouth open in a shaky moan.

She was trapped beneath it, breathing hard, completely overwhelmed.

The test wasn’t finished.

It had just entered phase two.

Life With Macromastia Rock Climbing

Most people would have given up by now.

Ever since she was 18, her chest has continued growing year after year, turning everyday activities into challenges most people never have to think about. But while doctors, friends, and strangers kept telling her what she couldn't do, she stayed focused on what she wanted to do.

Now a senior in college, she's still chasing her dream of becoming a professional rock climber. Every climb takes more effort. Every route requires more planning. Every hold is a little harder to reach. But she's determined not to let her condition define her future.

Today's training session wasn't about setting records. It was about proving to herself that she still belongs on the wall. One climb at a time. 💖🧗‍♀️

I Got This Submission Today...

One of our biggest fans just sent this in, and honestly, I had to share it.

Whether she makes the cut or not, you've got to respect the dedication. 💖

What do you all think? Should we give her application a closer look? 👀
