Overall, Mark found himself enjoying this convention more than he expected, even if it wasn't for the right reasons.

Sure he had been dragged there by his friend, had no interest in any of this stupid nerdy stuff at all, and everything felt way too crowded for him, but none of that mattered! He was ready to find a totally hot date and move on from his last girlfriend already!

She was being ridiculous before their breakup, so it wasn't a big loss, saying that he paid more attention to other girls than her. It wasn't his fault he noticed when girls were hot! She was just jealous she wasn't getting as much attention. He obviously hadn't bothered dressing up like all the people here though, not willing to lower himself to something so obviously lame, instead going for a normal hoodie, his friend having wandered off for something unimportant.

Nah, he had the real show, smiling as he watched all the cosplayers passing him by, dressed in all sorts of revealing outfits, whether it was schoolgirl inspired, superhero, or some other stupid thing, he didn't care. As long as it was sexy, he was happy. Mark probably wasn't subtle in his staring, earning a few furious mutters and harsh glares, but it didn’t faze him. If they didn't want people looking at them they should have just put more clothes on!

Only one of the girls actually went towards him though, scowling in annoyance, dressed as that crazy superhero chick from that movie a while back, barking on about him being a creep and how he was the problem. Or something like that, he wasn't really listening. His indifference put the girl over the edge as she hissed.

"You're the worst! You don't even appreciate all the work we put into our costumes! You're just treating this like a damn strip club or something!"

"Hey, it's not my fault! You should be happy that I notice how hot you all are! I'll just go somewhere else if you're going to be a bitch about it!" he shouted back, walking away as the cosplayer grinded her teeth in fury.

"That's it! You're just stupid and horny you pig! This should teach you a lesson on fucking respect!" she shouted, swinging her fake hammer back before slamming it on the back of Mark's head.

BONK

"A-AH!? GIRL WHAT THE HELL!? I’LL FUCKING SUE YOU FOR ASSAULT Y-YOU... h-hehe... b-bitch?"

There wasn't any pain, or even the mildest of injuries, Mark instead finding a strange, almost pleasant feeling going through him, his body shivering and twitching like he was being shocked. He was giggling a little too, even if he had no idea why. This wasn't funny! This was really s-strange and... a-and...

"H-hehe? W-what... what d-did you do! D-did you- p-pfff! Drug me!? Where did y-you go!?" he managed to get out, shivering as he found the girl had vanished into the crowd, the man leaning against a pillar in support as he took deep, heavy breaths.

Something was wrong, something was so fucking wrong, every inch of his body was tingling, almost burning with acidic pleasure, discomfort graduating into full on pleasure, the roughness of his flesh eroding into an extreme, perfect softness, his eyes spinning from reluctant bliss as the giggles continued to slip free, no matter how much he tried holding them back.

His hands looked wrong, shrinking into his sleeves as broadness melted into dainty, almost girly shapes, Mark certain he was simply seeing things as his heart pounded.

"This isn't r-real! That girl j-just gave me a concussion o-or... hehe~... something!" he slurred to himself, his brain throbbing, the pounding in his chest beginning to turn sensual.

"U-um... h-hehe... a-ah~? W-why..?" he gasped, twitching as his shoulders rounded down with sickening crunches, his plain shirt beneath shifting and teasing his reactive skin as his cock throbbed excitably within his jeans.

Mark was burning up, moaning as he pulled up his hoodie, running a much too small hand over a core that had only just decided to give up its hardness, melting away its worthless alpha male muscle in exchange for slim, alluring fat. The melting mass swirled inside for a moment, giving the man enough time to let out a confused, giggly noise, trying to understand why he suddenly had a sexy, womanly midriff before the sound turned into an eager moan.

He gasped, the changed clothes pressing tightly against his nipples, the man staggering drunkenly away from the crowd, gasping as the world spun, everything melting together in a haze of terror, bliss, and giggles. W-what had that b-bitch done to him? W-what was... w-what was h-happening?

His body slammed against a vending machine, a hand glued to his shaft as he jerked in conflicted bliss, the newfound swelling in his chest proving to have intense and wonderfully pleasurable side effects. "Something's- a-ah~? Coming~? H-hehe~? I don't..."

That was all he could get out before the moans and giggles consumed his speech, eyelids growing heavy, certain he had to be seeing things when his hoodie opened by itself. He was speechless, watching as a set of jiggly breasts bounced free as they continued to expand, the sight feeling like it was making cracks in his mind from just how insane it was.

The feelings made him pant like a horny animal, the sudden collapse of his spine sending him tumbling forward as he lost a full head's worth of weight, his body forced to present his still expanding burst further while the world spun around him.

"B-breasts? I-I have boobs? B-but I'm not... I'm not s-supposed to have... g-giggle~..." his voice rose in pitch as something slid down his thinning throat, nothing making sense as his hoodie continued to open. He sounded like a girl, he looked like a girl, he had b-breasts, this couldn't be real, this was i-insane!

"C-crazy! This is f-fucking c-crazy! I mean I should know! Teehee~! This is realllllllll n-nuts~! Haha~!" he had no control over his inflating lips, any thought he had forced to slip out, the electric buzzing washing all over his face.

His cock was harder than it ever had been before, eagerly throbbing for the emerging beauty, Mark sharing none of the enthusiasm as he wobbled and moaned all over the place, running a hand down his new slender curves. It couldn't be real, but he had never felt something more amazing in his life, whatever was happening putting sex to shame as the muscles in his arms broke down from exposure to the new feminine chemicals that were brewing within.

They looked so small now, so powerless, but he knew that appearance was deceiving, the power within surging as he felt his mind pulse, screaming as a crack broke through it.

"S-something broke? But I d-don't... I don't s-see it! W-where... h-hehe? Is it invisible or something? B-but- heehee~! W-where am I supposed to-"

CRACK

"K-KYAHAHAAAAA~! T-THERE IT IS AGAIN~? T-THERE'S ANOTHER ONE~! H-haha~! F-fuck y-yeah~! F-feels so- teehee~! O-oh gawd what's happening why is this- what's- m-my brain~? The c-cracks are in m-my fucking m-m-minnnnnnnn- GAH S-SHIT~!?"

He was going crazy for the pleasure, squealing as his jaw exploded like a round from a shotgun (those were always fun to use), her entire face scrunching up literally and from pleasure as it collapsed into womanly perfection. But Mark could barely focus on that, not when his thighs had become hot spots for pure euphoric heaven, the man forced to squish them together before screaming as they bulged with mass, plump fat rushing into them at rapid speeds.

It was like he was being tortured, the sheer fat crushing his poor shaft between the pillows, his wriggles only making it worse as he was trapped in some kind of ecstasy-ridden hell. But he also couldn't stop the manic smile, an insane grin twitching onto his face against his will, the poor man shuddering as he felt the mental cracks spread.

It was like someone had gone from lightly tapping his mind to repeatedly slamming a hammer into it, Mark internally frightened to death as morality was consumed, desires and normality were thrown out and the fantastical took hold.

He was turning into a girl. That was terrifying enough, but becoming an utter maniac was even worse, yet all he could do was laugh and giggle like a mental patient, shuddering in terror as he looked down at himself, watching as the growing locks cascaded downwards, blonde spreading from the tips as blue consumed his left eye, helpless as his sanity continued to go down the drain.

"Giggle~. O-oh gawd- oh h-hehe~! S-shit~! I'm l-losing my mind~! Haha~! I-I- giggle~! Can't h-hold on much longer~! Haha~!"

He was clutching his head like he was holding the pieces of his mind together, desperate to keep it from shattering forever, his eyelashes fluttering as the rest of his hair was consumed by blonde softness. He couldn't stop it from taking it all, or it being styled into distinctive, cute twintails, the man shuddering and laughing as his cock twitched in growing enthusiasm, his thighs doing an excellent job at working it up.

Whatever was happening, it was clear he was losing, his mind falling apart at the seams as his hoodie opened itself up, red bleeding into the plain colouring, his flexible body stretching from bliss, his pants tearing and shredding apart to reveal his rapidly slimming legs.

Only the frame of his pants remained, the fishnet stockings digging into his sensitive skin as they continued to unravel, his cock struggling in the increasingly tightening legwear.

"S-stop- hehe~! I-it! Stop- h-haha~! changing~! P-pfff~! My fucking h-head! You're breaking my d-damn minddd~!!!!" he was barely holding himself together, everything slowly chiselling his sanity away as his shaft throbbed in desperation.

His pants were turning red and black, shrinking to almost absurdly short shorts, the kind he would love to see a sexy woman walk by in, and something that only emphasised his increasingly feminine form. His shoes shrank, forcing his feet down, the broadd shapes cracking down as they shrank.

Everything was breaking. His mind, his terror, even his body, Mark unable to stop laughing despite his terror, unable to help himself. I-it was... it was just s-so f-funny!

Socks began to lengthen, slowly climbing his supermodel legs as he bucked, feeling his hips burst free, the pressure and pleasure mounting on his shaft as the man was struck by the realisation that was about to witness the end of his sanity.

He was shivering and shuddering in terror, screaming as his cock was helpless to defend itself, the shorts sending it hammering back inside him, his eyes spinning as it crashed into his mind, his brain falling apart in sync with his masculinity. Mark was desperate to keep his mind together, applying more and more force in a panic, whimpering and shaking like he was able to make a difference.

It was hopeless though, his fate inevitable, his cock pounding away as slowly, he reluctantly removed his shaking hands, gasping as his thighs squished, everything breakingggggggg at once as with one final orgasm his cock popped out of existence. The new girl raised her arm, feeling her mind as her old identity shattered like a mirror, the fragments of sanity beginning to reform into an identity much greater than the pathetic boy could have ever hoped to be.

"Heheheheheh~... o-oopsssssssss~. D-did I b-break that~? H-hehe~."

She giggled at her own comment, barely keeping herself together as she teased her new opening, drooling and smiling in crazy delight. S-she was a girl now! That was r-really odd! But also s-sooooooo much better right? Boys just suckeddddddddd!

"Y-yeah... being a sexy g-girl is like... the... h-hehe~! Best thing ever~! Haha~! Ohhhhhhhhh m-my outfit is almost done too! Heheheh~! About fucking time~!"

The only snag was that she was still unsure what her damn name was! Her old self was so uncultured there was nothing to draw from beyond “crazy chick”! Not only that, she had the feeling it was painfully obvious too! Ugh it sucked! At least her outfit had almost finished, the fishnet stockings finishing forming, her tiny shorts and small jacket only emphasising her amazing curves and figure.

There was only one thing left to change, the growth of her ass, a fitting finale for the experience, the new woman squealing out giggles as her rear surged outwards like an inflating balloon. It was pumped full of mass, bouncing and jiggling as her fun-loving mind rebuilt itself, make-up appearing on her face while blue and pink highlights added some extra flair to her hair.

"Ah~! H-heheh~! Yesssssssssss~!!!!!!! I'm h-hah~! I know~! It's coming back to me!" she cried, eyes wide as she bucked and squealed, breathless as she noticed something appearing on the floor, a large, cartoonish mallet coming into existence.

It made her eyes sparkle, the woman's thoughts finally focusing as her name returned to her, a grin washing over her features as she picked it up, savouring her new form right as her ass finished expanding.

"Ohhhhhhhhh duh! Teehee~! I know who I am silly~! H-hehe~! Hereeeeeeeeeee's Harley~!"

She giggled to herself in joy, posing with her new wonderful body in delight, loving the ways it could bend as she was filled with excitement. God it was the worst being a boy! Especially an asshole like that! It felt so good to be out, and she was certain she was never going to go back in again~.

Harley laughed again, equally happy to be in a world when she could choose her actions for herself, all of it making her very giddy as she looked around. Yep, she could really have some fun here. The crowded sections looked like they had a ton of people dressed like her too! Oh she totally would have to say hello to them, without freaking them out of course, as fun as that would be.

"Ohhhhhhhhh I have to find a hot Ivy cosplayer too... or I could just make something more real myself... hehe~" she smiled, swaying away to mingle with the crowd, fully intent on enjoying the convention to the fullest~.
