A Cosplay Convention

John Doe is a security guard who was hired to check the cameras at a cosplay convention where the sexiest and most famous cosplay girls on the internet were.

But John had other plans, a few days ago a mysterious App called "Reality Change" appeared on his cell phone, doing tests in his apartment complex, he realized that the App can change the personality and vision of a person's social norms through of turning his 60-year-old neighbor into a horny Gilf who had one-night stands with young men she met in nightclubs

"Let's see what's on today's menu" John said while he was in the camera room checking the screen, the camera room is an austere room with only a screen, a chair, a table and an armchair

The convention takes place in an indoor convention center, there were dozens of cosplayers and thousands of horny nerds who attended hoping to find their favorite cosplayer wearing little clothing and a total of 10 underpaid security guards.

“That's Jessica Nigri, she's wearing a Scorbunny cosplay that exposes her ass,” John said as he looked at her through the Camera.

"Bunny Ayumi is wearing a rather simple Sadako cosplay, but with that pair of tits, anything looks amazing on her" John said as he looked at her through the Camera

"UniqueSora is wearing a Rosaria cosplay from Genshin Impact, if Bunny already had beautiful tits this bitch is on another level, those milk bags are bigger than her head" John said while looking at her through the Camera

“BishoujoMom is wearing a Catwoman cosplay if the other 2 were already a pair of boobs and a fat ass this woman was a fertility goddess dressed in a leather outfit” John said as he looked at her through the Camera

It's already decided John thought to himself as he took his cell phone and wrote

Everyone who is cosplaying will become real, but horny versions of their characters looking to fuck the man in the camera room

“Wait this is not right…. I can't be so selfish I have the opportunity to fulfill the sexual fantasy of a lot of people” John said as he added more specific text.

All those who are using Cosplay will become real, but horny versions of their characters who want to fuck the man in the camera room, once one reaches the camera room the goal of the other girls will change: they fall in love and have sex With the first man they see, the rest of the event attendees will not see anything weird in that, they will just see him as a lucky guy

Once John wrote that and pressed the "Alter" button on his cell phone, things at the convention began to change:

Jesica Nigri's cosplay ears became real and body temperature began to rise

Bunny Ayumi's gaze turned blank, her body turned cold and she began to levitate a few inches off the ground.

UniqueSora started to walk in the same way as Rosaria as she walked with a Spear.

BishoujoMom started purring with a cat as she walked and wagged her ass back and forth.

John looked at all those changes through the cameras but what moved him the most is to see how the 4 girls went to the camera room
