Chapter 1: Twilight Sparkle, the first victim

One normal night in Equestria, Twilight was cleaning up all the clutter in the basement of her castle, when suddenly she finds a barrel she remembered getting at Canterlot and inside was a mysterious yellow book with a hazmat biohazard symbol on the cover. She becomes curious to know what it’s supposed to be used for. She thought it was a spell book, so she lifted the book out the barrel with her magic.

She opened the book, flipped through the pages with her magic coming from her horn and she finally found a page that she thought she was looking for. Little does she know that she was about to make a terrible mistake!

“Oh, finally! I’ve got the spell working! Now let’s see what it does…” Twilight said, curiously.
She switched her cutie mark with the symbol on the book. Now her cutie mark is now a radioactive biohazard symbol.
“It’s a shame I couldn’t find any information on this thing, I could’ve done with the background on it before trying it out but there was none to be found. Ah, well.” Twilight said, disappointed. Suddenly, she feels a tingle in her flank. “My cutie mark feels all tingly…” she exclaimed, confused. Twilight Sparkle thinks it was just a side-effect of using her own magic on herself.

“Amazing! The spell changed my cutie mark! This could change everything! Ponies could be able to have any talent they want, if I rewrote the spell to give a certain retain cutie mark anyway…” Twilight exclaimed, excitedly. The excitement wouldn’t last very long however, as she sees that her flank starts turning yellow.

The excitement wouldn’t last very long however, as she sees that her flank starts turning yellow.
She looked back to see that her entire ass was turning into yellow rubber in shock. “Huh? W-what’s going on, my flank feels strange… Oh sweet Celestia! W-what’s happening to my b-body!” She panicked.
Her back legs turn into yellow rubber and her hooves turn into black ridged boots, which confused her (considering why her skin was turning from fur into rubber).
Her tail started turning into a block of black rubber, the yellow latex spreading to her front (right up to her neck), with her wings becoming sealed in yellow rubber pods.
Before she could say anything else, she felt a pulsing itch on her crotch. A yellow latex bulge grew on her private area! Twilight took a hoofboot and gave it a tiny poke and it resulted in her body getting hot and horny. “What the…?” Twilight exclaimed, confused and shocked. She touches it again but has 2 hoofs rubbing it.
“This is getting stranger and stranger,” Twilight said, already feeling her body getting even more horny.
After she rubbed that bulge on her crotch with so much force, she already sealed her fate with becoming a horny ponydrone. “This feels tight,” Twilight said, just before her face is going to get dronified. Tight as in she would be wearing a skintight bikini!
It was then her face became covered in yellow latex! Her eyes get forced open and become dry as they turn into pink inanimate camera lenses. Her mouth is getting sealed shut by strands of rubber while mask valves appear on her cheeks like rubber bands. “Make this stop! What’s happening to me?!” Twilight yelled out, but to no avail because her mouth is almost gone! “Where’s Spike when you need him?!” those were her last words she ever said said before her mouth becomes sealed away.
Thus, her transformation has been completed. She then collapsed on the ground, laying down on her belly rubbing her boot on her new bulge.
Soon, she stood up forgetting that she was no longer a pony, she’s a mindless latex drone with a bulge on her private area to rub (masturbate) herself with NO relief.
