“Miss Hooper! Miss Hooper!”

The voice erupted out of the megaphone, more insistent the second time.

The call came a few more times. Then, quietly, but still very much audible:

“Where is that diva?!” There were a few panicked looks, after which one of the runners whispered something in the director’s ear.

“I don’t give a fuck if she heard! She’s ruining my movie!” Came the bellowed response, straight through the megaphone.

But Kathyrn did hear. She’d heard everything. Only fifty yards away, huddled in her trailer, she sobbed quietly, praying for it all to go away. Only a glowing yellow bottle gave her any semblance of reprieve, but that had its own fears attached.

Kathryn was, in actress terms, old. She was in her mid-30s, but this was Hollywood, and in the roles she excelled at – glamorous heroines – there were thousands – millions – of younger, prettier, perkier-breasted girls just itching to take her place.

Kathryn was beautiful – tall, slim, gorgeous blonde shoulder length hair – and after the fine folks at hair and make-up had been over her, she looked stunning. But even now, looking as good as it was possible for her to look, she stared at herself in the mirror and couldn’t shake the inalienable fact: she was getting too old for this shit.

The megaphone again: “That’s it, we’re wrapping for lunch. If you’re not out this afternoon, don’t bother coming out at all!”

Kathryn shuddered, involuntarily. The idea of stepping out of her trailer was terrifying to her. The director was a powerful lady, and if Kathryn didn’t get this right – didn’t look right – that was it. Curtains. Or worse – theatre.

Kathryn looked over at the glowing golden bottle, sitting by her massive mirror. What had the lady said? “It’ll make you a big star?” Kathryn had asked everyone on set if they knew someone who could help her out, and one of the old teamsters had suggested a back-alley dispensary in downtown LA. “Lots of stars go there”, Kathryn was assured.

The place had been dark and creepy, lit only by a faint golden glow which emanated from the various bottles lining its walls. The lady behind the counter was frighteningly young-looking and incredibly well-proportioned – even for LA, she had colossal breasts. Kathryn had often longed for a massive chest; it would have made some of her more action-based roles more challenging, but she loved the idea of being really huge-breasted. She’d never liked the idea of surgery though.

The lady had slipped a hand between her massive cleavage, and brought out a single, small vial. “I like your work. Take it. It’ll make you big.” Kathryn had taken it with a shaking hand, and went to leave.

“Be careful. It’s powerful stuff.” The lady had called after her. Kathryn adjusted her sunglasses, and stepped out into the bright, glaring LA sunshine.

Back in the trailer, she swallowed deeply, looking at the vial with a mixture of lust and terror. What would it do?

A trudge of boots by her trailer, and muttered, cursing expletives.

Kathryn knew they were muttering about her. She’d screw this picture if she didn’t look right.

And that was what mattered.

She took the bottle, and unscrewed the top. It smelt incredibly strong – almost acidic. She closed her eyes, lifted the vial to the ceiling, and plopped a couple of droplets into her mouth.

It tasted better than she expected, but still very sour.

Kathryn sat back in her chair, and smoothed out the red dress she’d been given for the cocktail scene they were due to film. It was loose on her, and this upset her. She’d had her measurements taken perfectly. She felt this was a stab at her – she wasn’t curvy enough! Maybe her agent had forced the director to take her on. Either way, she wasn’t wanted here, and it hurt.

Kathryn looked at herself in the mirror, and examined the crow’s feet gathering around her eyes. Suddenly she hated this business, and what it did to people. So what if she didn’t look like she was twenty any more?! She wasn’t twenty any more! She was just about ready to –

“Oh my god!” Kathryn looked to her face, and saw it…tightening. Her wrinkles were pulling away, to be replaced with beautiful, taut, perfect skin. She patted at her cheeks, marvelling at their youthful splendour. What the hell was this?!

At the same time, she felt herself widen in her chair and push slightly against the curved, golden armrests. She jumped up in her seat, and examined her behind, which was…bigger! Her booty was slowly swelling outwards. She grabbed it and felt how tight and pert it was – there was no flab to speak of. It slowly bulged forwards, pressing into the red dress, which was tightening exactly where it should, as her curvaceous butt rounded her thin frame out.

Then she felt her chest.

Kathryn looked down at the tiny breasts that were all she’d had her entire life, and gaped as they began to slowly bulge forwards. She couldn’t believe it! She was growing tits! From tiny bee-stings, her boobs swelled bigger and bigger, slowly expanding, filling out into two small mounds, poking out into her dress, which tightened around her shoulders. Tight! It was a little tight! She couldn’t believe it. And still she grew.

Sitting herself heavily back down in her chair, (she already felt heavier) Kathryn felt her ass continue to expand, bulging outwards, pressing a little into the armrests of her chair. She loved this feeling of growing bigger, swelling up to what she’d always felt was the size she deserved.

As her ass expanded, she felt it bulge into the edge of the chair as her hips widened, and started to grow wet. She never thought growth could be this arousing.

Her breasts, meanwhile, were showing no signs of stopping. They had swelled out a couple of inches from her chest, and were now snugly nested in her tightening dress like a couple of softballs, pressing out in perfectly round orbs, gorgeously pert, with two hard nipples poking out of her now very tight bra.

Kathryn thrilled at the thought that she might need to go back to wardrobe. How was she going to explain this?! “Growth spurt?” She giggled to herself. As she laughed, her boobs jiggled, and continued to grow, slowly but surely. Kathryn found one hand cupping an expanding breast, feeling it swell bigger against her palm, and the other drifted to her open legs, rubbing against her increasingly wet cunt.

She moaned, biting her lip, as she started to play with herself while she grew. She moved her legs wider apart so she could get her hand further up there, but found the sides of her thickening thighs pressing quickly against the sides of the chair. Her legs and ass had gotten so wide!

Kathryn stood up in front of the mirror, struggling a little with her new weight, and admired herself in profile. She was fast developing an “S”-shaped figure; her breasts poked out a good five inches now, like two large balls, and her ass did the same on the other side. Her red dress was actually quite tight now, which felt incredible. Kathryn loved hearing it stretch and move to accommodate her swelling form. This potion was incredible! She wanted more.

Throwing caution to the wind, Kathryn took another sip of the liquid – it was now about half drunk. She sat back down, eager to feel the growth again.

It was stronger this time. She wondered if she’d compounded the effects. Her ass began to swell first, pressing hard into the arms of the chair. She was getting really wide now – as wide as the chair was – and was developing a tremendous, swollen booty. She found herself wishing some big-cocked stud would come in a shove his dick into it.

“Wait, what am I thinking?” Kathryn said aloud, surprising herself. She loved sex, but this kind of thought process was not her usual style. She had recently divorced her husband – he’d left her for a bustier, younger model (which definitely hadn’t helped her self-esteem) – so she hadn’t had much cock in a while, but her libido was definitely not like that this. Was the…potion, for want of a better word, enhancing this too?

Snap! Kathryn’s bra burst off as her tits surged forwards, bulging bigger and larger as her red dress began to further tighten around her burgeoning bust. Her tits were approaching the size of melons now, and Kathryn couldn’t help but grab both nipples and start to play with then, hard. Her tits were already so big and swollen, bulging out in two large curves – she couldn’t imagine them getting any bigger. But as she tweaked and rubbed her nipples, she could feel the expanding tits beneath them growing bigger and heavier with every passing second.

Kathryn gasped with arousal, as she blew up larger and larger. Her dress was getting really tight on her incredibly voluptuous figure. She was all tits and ass now – what looked like FF-cup breasts busting out the front and an enormous, swollen ass in the trunk. She looked like the curviest of movie stars now, and showed no signs of stopping.

The chair started to groan as Kathryn bulged further into it. She could feel her big fat ass cutting into the armrests as it grew bigger and bigger, and even though it was a little bit painful, she loved the feeling of being too big for the chair. Stupid fucking chair. Should’ve been ready for my epic ass. The chair creaked further as she blew up bigger and bigger, her big fat cheeks pouring past the armrest, bulging over it. The chair was coming apart, and her dress with it.

Kathryn looked down at how wide she was, and was instead struck by just how huge her tits had become. While she’d been practically writhing with arousal by how big her ass was getting, her tits had been swelling bigger and bigger, and were now approaching the size of watermelons on her chest. Her dress was incredibly tight now – it looked like it had been painted on – and her massive swollen tits were bulging out wider than she was.

Even though the dress was pulled in tight to her body, there was a couple of inches of cleavage on display – her tits were just too big to be completely hidden. But after the cleavage ended, a massive overhang of bust filled Kathryn’s entire vision. It was like looking down on two huge, over-inflated red balloons, which swelled and wobbled larger with each passing second. She could hear the fabric of the dress giving way under her enormous udders, and this sound melding with the shattering of the chair was a perfect symphony to her ears. She was bursting out of everything that came into contact with her. Getting so big.

With that thought, Kathryn tried to move her bulging legs to either side to slide a hand inside herself, but they wouldn’t move. Her massive ass had completely wedged into the chair, and her legs were too swollen to have any give. This wouldn’t do.

Kathryn stood up, taking the chair – wedged between her massive ass – and waddled to the counter where the vial of liquid was. She had to bend over to move, and she could feel her enormous udders hanging down, threatening to burst out of the dress, stretching bigger with every second. Just how big would she get?

She could almost feel her tits press into her knees – they were such massive, swollen balloons – but she made it to the counter, and picked up the vial. Half left. She took one more swig – only a quarter left.

Instantly, Kathryn bent over further – her insides were on fire! She felt her tits surge forwards, creating tears in the fabric was her dress struggled to contain her enormous, swollen mammaries. She fell backwards onto the chair, which was she was luckily still wedged into by her growing ass, but took a serious battering when she fell back onto it. She was getting huge now. Each sip seemed to be more powerful.

As she continued to bulge bigger, Kathryn suddenly realised she was too big for the movie now. They’d never be able to explain her size discrepancy – and they were already a way through filming! This sudden bolt of fear was eclipsed by arousal as her chair shattered, her massive ass tearing it apart, and she fell to the floor.

As she lay there, breathing deeply, her fall far more padded than she was used to, she could feel herself lifting up as her butt continued to grow and widen. She could hear the stitching give way as her massive hips blew up wider and wider, and her ass got fatter and fatter. Her dress was tearing to shreds as she ripped through it.

Lying on her back, all she could see in front of her was an impossibly large mountain of breast. Her tits were tremendous. Beyond description. She knew they were way out of US bra categories. She’d have to get them custom-made from now on. The thought excited her even more than she thought possible, and she moved one hand around her enormous mounds, which looked like they jutted up into the air about twelve inches (and were still shuddering and growing larger) and slipped a digit inside herself.

The feeling was electric. Everything about her was enhanced – she was becoming pure pleasure. As she reached a tip of a finger towards her clit, she could almost already feel herself touching it. The anticipation was almost too much.

Kathryn felt like she’d been zapped with a cattle prod. One touch of her clit sent shock-waves through her entire body, which left her breathless. Her massive, still-growing tits heaved larger and larger as she gulped in air. She could hear her dress shredding under their indescribable bulk.

Kathryn reached a shaking arm for the bottle, but it was too far away. She was so close to being the biggest, but that would have to wait. Even craning her neck was a challenge – there was so much weight on her chest, she wondered if she’d ever be able to get up. Looking down on her was like seeing a stick with two massive water balloons taped to it. Her figure was preposterous.

As her ass continued to grow, it slowly bulged through the burst stitches, massive blobs of white flesh poking through tight holes, and the dress slowly unpicked itself. The same was happening up top, as Kathryn’s tits approached fourteen inches, and the dress was unable to constrict them anymore.

Kathryn knew bursting out of the dress would be the thing that did it for her, so, bracing herself for feelings she’d never felt before, she reached a tiny-seeming hand past her impossibly-wide hips and ass, spread her legs as wide as she could (destroying the lower-half of her dress completely) and started to rub her clit.

It was almost too much.

Delight so strong it was almost pain flooded her body – Kathryn was becoming a being solely devoted to pleasure, and her body reflected that – everything was so on edge, ready to erupt in arousal, and when she rubbed her clit, her mind exploded into colour.

Her tits continued to bulge, but were tearing through her ridiculously tight dress, which was popping at every single seam. As her tits expanded larger and larger, Kathryn watched through wide, crazed eyes as her enormous figure bulged bigger and bigger and bigger.

“More! More!” She thought, rubbing her clit harder and harder, reaching another hand in to penetrate her g-spot.

This combination of pleasures, coupled with the fact that she had to have her legs so wide in order for her massive thighs not to rub together coupled with the fact that her dress shattered open to reveal breasts of such magnitude she didn’t know to describe them, flooded Kathryn’s mind with chemicals of such power, she could do nothing but scream.

And then, blackness.

**

Bill slouched his shoulders as he made his way towards Miss Angelica’s trailer. He’d really drawn the short straw here. But the director was so pissed, someone had to make sure the talent was out and ready. He really thought Kathryn was a good actor, but she always looked so small and frightened these days. It was a damn shame.

Still, talking to her had become tough the more she retreated into her shell, and beckoning her frightened, mousey figure out onto set felt cruel, somehow. Just another case of someone the entertainment industry had chewed up and spit out.

He stood in front of the trailer. Man, he did not want to do this.

He lifted a hand to knock, then brought it down again.

“C’mon, Bill. She’s just scared.” He said to himself. He breathed deep, and knocked.

The door slowly swung open, with a creak.

“Miss Angelica?” Bill ventured.

“Come in.” Came an impossibly husky voice.

Bill’s eyes flew open, and all the blood in his body ran south.

“Miss Angelica??”

He couldn’t believe what he was seeing.

The voice came again from within.

“Close the door. And call me Kat.”

TO BE CONTINUED…
