As you tried to run through all the mess around you, you heard some steps chasing you, that were heard louder every time you ran, it was extremely difficult avoiding some obstacles and running from a possible "monster girl" thing at the same time. Some minutes of running passed and you quickly crossed a corridor but unfortunately you found something inconvenient for your situation, a wall, the thing was slowly approaching you as you feared for your life thinking of thousands of things that would happen to you, then its shadow appeared that revealed being the silhouette of a man, after that the atmosphere lightened as you saw it was a man with a ripped lab coat that seemed friendly.
"*Cough cough* sorry, I'm not used to run like this... *Cough cough*" the man tiredly said.
You tried to help the man putting one of his arms around your neck, and you saw something that caught your attention, a little pin in his lab coat said Dr. Fielding, it was the doctor that wrote the notes for you, but how? You though as you kept helping him without asking.
"I know, I know, it's not easy to digest all this information at once, but I'll try to clarify everything, come here, I'll answer all your questions" he told you.
At the same time he was guiding you to a safe place he explained.
"You see, this world is obviously not like you remembered it, it's now a completely chaotic version of the older one, with the inclusion of... Monster girls" the doctor exposed.
"Speaking of that, what is this all monster girl thing? What are them? What is this Succubus Queen?" You asked.
"Oh yeah... Her... Well, as you see, the monster girls were an experiment we had in mind. We discovered magic was real many centuries ago, but we kept it in secret from the public. At first we tested it in animals, but nothing happened, after some research we discovered that magic was used by a group of animalistic women that suddenly disappeared, so that drove us to our next plan, test it on humans, which we put in that cryo pods, with you as one of the test subjects. The first experiment was a success, the subject assimilated his powers and was able to control them by his own, but then... That's when all this started... Hid body started to develop some white fur in his extremities, where also appeared black spots, his chest grew large breasts, his face and voice turned more feminine, his penis shrunk leaving a vagina in his crotch and an udder grew below his belly, he was no longer a man, but a woman with cow features that didn't delay in turning against us" the doctor explained.
"And what did she do to all of you?"
"Magic, Raymond..." He continued, "She used it on us turning all my assistants into that monster girl things and and stole the magic, then she did something strange that none of us could guess, summoning a pink light that was shot at me, then I felt how my mind was no longer alone in my body, another being was inside me..."
"The Succubus Queen..."
"Vinamara was her true name, all the time she fills my mind with conquering the world and turning it in her perfect place, every time I struggle to not being consumed by her"
"And what about now?"
"She's... um... sleeping right now, I managed to make her sleep for long periods of time, so we're safe for now *cough cough*, by the way, we reached the place I wanted to show you"
You looked around you, it was an forgotten, messy and rusty chamber that make you doubt if following the doctor was the right decision. "Why are we here?" you asked.
The doctor began to laugh, every second louder, seeming extremely fine. "Did you seriously fell for that? I always knew humans were dumb beings" he laughed.
"Who are you!" You angrily asked.
"The great and majestic" he screamed as he raised his arms. The doctor's body grew bigger reaching the 7 feet tall, his clothes ripped even more exposing his naked body, his chest expanded turning into a pair of H cup breasts, below his ballsack a vertical opening appeared morphing into a vagina, his skin turned purple as his nails turned black and long like claws, then he grabbed his own face and ripped it revealing a feminine face who its hair expanded and turned from brown to black, for the final changes a pair of horns grew in the top of her face as a pair of bat wings appeared in her back.
"Y-you are..." You sweated while pointing at her.
"Yes sweetheart, I know what are you thinking,
and you are lucky to be in front of, Me, the wonderful Succubus Queen" she giggled.
"Wh-what d-did you do to the doctor!" You screamed.
"Huh? Marvin!?" She let out a big loud, "He was an annoyance in my body, honestly he was strong trying to stop me, but wasn't enough, now I am completely me, not a single trace of him exists, and he's gone, forever~" She smiled and looked at you. "Now, I could easily transform you into a monster girl as one of my subordinates, but that isn't entertaining, I'll have more fun doing this little thing, I hope you like it~" she snapped her fingers.
The door you entered closed reinforced by more steel doors leaving you trapped in the chamber, then some doors opened, where came out a pair of monster girls, one was a lamia, a normal naked woman with the exception that her lower body was the one of a long snake, by the other side, the other girl was entirely covered by yellow fur, her legs were very feline, she had claws in both hands, a tail attached to her butt and her face was also covered in fur, with a cheetah snout replacing her nose.
"I hope you have fun with my girls darling, see you later~" the succubus turned into a pink smoke that quickly vanished in the air, then you looked at both monster girls worried about what would happen to you.
