"Wait a minute... the CGA expo, that's today" Colin said, gazing out towards the area south of the horde. "I have to warn everyone there."
The CGA was an expo held at the town every year for comic books, video games, and anime, and it was always packed. If the bimbos got to the convention center, the horde would be too big to stop. He ran as fast as he could for about half of the required distance before getting winded. Nevertheless, he pushed on with all of his might, in hopes to stop the horde.
Little did he know that he was already too late.

Colin slipped through the gate and gasped in horror. Bimbos as far as the eyes could see, sporting costumes torn by their voluptuous curves.
"Oh man, I'm too late." Colin groaned in dismay, seeing the uninfected entering tents the bimbos had overrun. And on the other side was the emergence of busty, barely clothed women. He couldn't figure out what to do. And then a hand yanked him into a nearby stand. Colin got a glimpse of what was inside, and recoiled in fear. Standing there were four girls around his age sporting cosplay, and they all looked bimbofied.
"Stand down, I'll shoot!" Colin said as he raised his pistol.
"Stop, we're not infected!" A girl shouted. She was dressed as Princess Peach, tan skinned with blonde hair and a bust that looked to be size D.
"Prove it! What's two plus two? Name the first US President! When did Christopher Colombus sail the ocean blue? What do you get by mixing red and blue?!" Colin questioning in hostile panic.
"Four" the Princess Peach cosplayer said.
"George Washington" another girl answered. She was dressed like Morrigan from Darkstalkers, with a size DD rack and bold green eyes draped by mint green hair.
"1492" the third girl replied. She was dressed in a Zero Suit Samus Outfit, and looked remarkably like the fictional bounty hunter of Colin's dreams, albeit with DD tits and a butt that threatened to tear the back of her suit out.
"Purple" the fourth girl said. She was Asian, cosplaying as A teenage Chi Chi from Dragonball Z.
Colin was relieved that none of them were bimbofied and lowered his gun.
"So how do you..." Colin began asking.
"Look like this?" The Chi Chi cosplayer interrupted as her D sized breasts bounced with her approach.
"My dad works with a medical company, I managed to sneak these" The Morrigan cosplayer explained as she pulled out a case of syringes from between her breasts.
"It renders the virus incapable of altering your brain, but you still end up like... this." The Samus cosplayer stated as she lifted her breasts to make her point.
"How does it affect guys?" Colin asked.
"I was a guy before the injection." The Peach cosplayer replied.
Colin paused, and then asked "Is there enough for me to have one?"
The Morrigan cosplayer handed him the needle out of a case of six. With very little hesitation, Colin grabbed the needle. Swabbing his arm as instructed, he jabbed it into his vein and injected the concoction. His body hair and acne immediately began to vanish, and he was soon left, with smooth, unblemished white skin. He then drew his hand through his hair as it grew out and turned white.
"This next part's gonna hurt" the Peach cosplayer commented.
And sure enough, Colin fell over in writhing pain. He could feel his dick shrink before it pulled inside of him and two swollen vaginal lips formed over the gap. Then, his waist thinned out as his hips began to widen out and his rear inflated. He then felt the rest of his body fat move up and shoot out in a pair of Size DD breasts. He held his eyes shut as his face finished changing and his spine readjusted. After the searing pain resided, he opened his eyes and walked over to a dressing mirror. Sure enough, Colin had turned into a girl that looked like a bimbo.
"So, uh...."
"Cailin. Call me Cailin, I guess." She said, getting used to her pitchy feminine voice.
"Jamie." The Peach cosplayer said.
"Mona" The Morrigan cosplayer added.
"Rachel" The Samus cosplayer said as she greeted the new girl.
"Mei" The Chi Chi cosplayer added.

About four hours later Cailin emerged from the tent dressed as Weiss from RWBY, a cosplay disguise that sufficed with the spare costume clothing in the tent.
"Cailin, how are you holding up?" Mei asked.
"Well, it's a bit... tight" Cailin said as her breasts nearly threatened to tear the blue school shirt in half, "But it'll hold."
"Alright," Rachel replied, "Now let's get out of here, follow our lead."
~~~~~~~~~
For the twenty minutes it took to get away from the horde, the girls had groped eachother, spanked eachother, kissed, and giggled like idiots.
"Thank God that's over" Rachel sighed in relief.
"Now were do we go?" Jamie asked.
Cailin decided on heading to...
