Rainbow Dash wakes up strapped to a bed, her strength weakened and feeling drugged. Her pussy is shown along with her huge breasts and ass. The door opens, revealing TwiDroid.
"Twilight?! Am I glad to see you! Help me out of this!" Rainbow yells.
TwiDroid does nothing, which scares the pegasus. Then, the evil scientist enters the room, smiling viscously and sinisterly.
"I see you met my new slave, TwiDroid," he says.
"What have you done with Twilight, you monster?!" Rainbow Dash yells.
"I gave her a reason to live. Isn't that right, TwiDroid?"
"Correct. Thanks to master, I finally have purpose. I owe him my life," says TwiDroid.
"You owe him nothing Twilight! You better let her go or I'll... I'll...!"
"You'll do nothing! She is, permanently, my slave. I could have her kill herself if I wanted to. In fact... TwiDroid, get a knife and hold it close to your throat."
"Yes master."
TwiDroid walks away only to come back with a knife close to her throat.
"You wouldn't dare!" Rainbow yelled.
"I would. You see Rainbow, I have as much talent in magic as Twilight does. I wouldn't need her. Therefore, she's expendable. But I don't think you want to see your friend get hurt. All I ask is that you willingly give yourself up and join TwiDroid. If you accept, she will remain unharmed and you'll be added to my collection. refuse and you could end up killing your own friend. So what'll it be?" the mad scientist says.
Rainbow panics immediately. She thought about it and decided it would better to have her friend live than it would to see her die.
"Fine... You win..." Rainbow answers reluctantly.
"Good choice. Put down the knife TwiDroid," says the scientist.
The alicorn slave lets the knife go, letting it fall to the floor.
At least she's safe... the pegasus thinks to herself.
"Now time to begin," the scientist states.
"How are you going to make me your slave?"
"Through magic..." The scientist uses his magic to enter Rainbow Dash's mind. He sees a bunch of doors leading the thoughts and dreams of the pegasus. He instantly destroys all doors and replaced them with a new one. Inside this room is pictures of pleasure and obedience to her new master, with many sex toys inside. He finishes the spell and leaves her mind. At first, the pegasus says nothing, but later she opens her eyes, the eye color being green. She is released by TwiDroid and the first thing she does is got on the floor on her knees and gets into a begging position.
"Oh sweet and amazing master, please let me do the honor of sucking your cock?" Rainbow Dash asks.
"After we give you a new name..." The unicorn thinks and comes up with her new name. "You will be known as Rainbow Slut."
"Oh thank you Master! I can't wait to follow your orders!" Rainbow Slut said, impatiently.
"Oh I know you do Slut." The scientist smiles viscously. "I know you do."
Twilight Sparkle wakes up in a dark area, her breasts, pussy and ass exposed. She is completely frightened and confused as she looks around the dark room. She sees that she is inside some sort of capsule and tries to use her magic to escape, but the capsule is blocking her magic somehow.
What is going on? Where the hell am I? she ponders.
A door opens, revealing a young-looking unicorn. This stranger had a orange mane and a yellow coat. His eyes were the darkest shade of purple and had an insane grin.
Before she would think of the stallion as an enemy, she yells, "Hello! Sir?! Were you kidnapped too? Free me and we can escape this place!"
There was only silence from the unicorn. Finally, after a while, she realizes that the pony is not her friend. But it was too late as the pony presses a button, activating the machine the capsule is attached to. The covers for the glass of said capsule were closing. Twilight was now crying for help as the capsule covers finally closes. She screams as tentacles from the capsule hold her in the air in place and gag her so she could stop screaming. She tries to break free but the tentacles had a tight grip. Then three tentacles come from the left, the right and the bottom (which is mostly shaped like a stallion's dick). The bottom was the first on to get inside her, entering through her pussy. She blushes and moans a bit as it starts thrusting in and out of her. Then, the two tentacles from the sides enter her ears all the way to her mind, where the tentacles release tiny nanites to take control. At first, she struggles, trying to win the fight against the tiny machines. Unfortunately, the bottom tentacle, increasingly, has gotten faster and stronger. Twilight couldn't take it anymore and, eventually, gave up and cums on the bottom tentacle, her mind broken enough for the nanites to take over.
With her remaining free will, she thinks to herself, "Be careful, my friends."
She closes her eyes in defeat. The capsule covers open and the tentacles put her in a sitting position. Twilight say there, motionless. The unicorn walked up to her.
"TwiDroid activate," he said, finally, his voice sounding mature.
Twilight, now known as TwiDroid, opens her eyes, revealing no irises or pupils in them, representing the destruction of her soul. She stood on her feet.
"Awaiting orders, Master," she says.
"It is a success! I finally done it! I got a slave."
He quickly examines her body.
"And a sexy one at that. But I need more sexy slaves and I need them now."
He sits at his desk and looks at TwiDroid, smiling viciously.
"And she's my ticket to getting them."
