You'll never get away with this!
The Mane-iac smiled. Well, smiled wider; there was rarely a time that she wasn’t smiling, really. Or cackling madly, come to that. “Now, at long last, my doomsday device is nearly ready! Once it charges, there will be nothing anypony can do to stop it!”
“You’ll never get away with this!” Twilight shouted. The statement would have been quite threatening and heroic, were she not frozen in place. The power-nullifying hairspray was surprisingly effective, given it had been designed by an insane supervillain.
“Oh, but I already have!” The Mane-iac let out another shrill giggle. “The only question is, just how are we going to pass the time until it does? The villainess flung the Power Ponies into the cage she had expertly prepared beforehoof. There was a distinct clang as they landed, their immobilized bodies clattering loudly into place. “Oooh, idea!” The Mane-iac wrapped her tentacles around Rarity, and pulled her out of the cage. “I think I know just how we can spend the time after all…”
She waved a hoof at her henchmen. “Seal the cage and lift it up. We wouldn’t want our guests going anywhere, would we? Heheheh.” She pushed the Electro-orb into the machine, and was immediately greeted by a loud, teeth-rattling hum as the machine began its bootup sequence.
“You monster! What are you going to do to me?” Rarity’s body was completely frozen in place. Her eyes darted around for a few moments, but otherwise she was still.
“You know, Radiance, I always did love your mane.” The Mane-iac leaned in. “So expertly crafted, so carefully coifed. You clearly care about your appearance.” Her breath brushed across Rarity’s ear. “I always did love a mare who cared about her appearance.”
Rarity tried to flinch, but her body didn’t respond. The hot breath flooding her ear was, in some ways, even worse than losing her powers. “You’re disgusting.”
“Why thank you.” The Mane-iac pulled Rarity closer, their bodies inches away from each other. “But we haven’t even gotten to the good parts yet. Save your compliments.” She let out another chuckle, her tentacles writhing across Rarity’s body.
“Y-you wouldn’t…” Rarity whispered. Her body still wouldn’t move, her legs stubbornly stuck beneath her and her tail not even swaying as the Mane-iac effortlessly moved her about.
“Mmmm, your mane even smells nice.” The Mane-iac dragged her nose across Rarity’s bangs, and the deep, loud sound sniff echoed slightly in the cavernous warehouse. “And even after all those henchponies you beat up, your deodorant is still working. Mmmm.”
“You can’t do this! Especially not in front of all these ponies!” Rarity’s body was motionless. Every order she screamed at it did nothing. Even her rising wasn’t having an effect. The adrenalin should have made her sweat or flush or something, but her body was perfectly still.
“Oh, don’t be silly! I don’t mind at all!”
“But—” Rarity’s protest stopped before it began as a tentacle forced its way into her mouth. It was slick and soft and firm, all at the same time. It didn’t even feel like hair; whatever chemicals it had been soaked in had made it almost solid. And not the crusty firmness of too much shampoo, the pliant softness of skin.
“Now now, normally I like to hear begging, but it doesn’t become someone as pretty as you.” The Mane-iac forced the tentacle a little deeper into Rarity’s mouth. “Just sit back and enjoy it. Well, stand still, either way!” She giggled again.
Rarity’s eyes widened. She could feel another one of the tentacles working it’s way into her costume. The spandex was tight, and the tentacle worked its way up her ankle, she could feel the material stretching to accommodate it, pressing and squeezing on the rest of her body.
Rarity tried to say something, but all that came out was a muffled mess.
“Oh, don’t worry, I will. But it’s nice of you to offer!” The Mane-iac giggled, and another tentacle wound around Rarity’s neck and into her costume. Another slithered into her sleeve, and she could feel her bracelet press into her forearm briefly, painfully, before it slid onto the hair.
Rarity’s costume felt horrible. All the extra mass writhing through it had stretched it horribly. Every one of her joints was being choked by the fabric. She could feel it cutting into the back of her neck, and if it weren’t for the tenctacle wrapped around her throat, it might have been a serious problem. A tentacle shifted, and the crotch shrunk, rubbing into and against her groin.
Rarity let out a pained gasp. Even muffled by the tentacle in her mouth, it spread across the entire building.
“Oh, a little too tight?” The Mane-iac chuckled. “here, let me help you with that.”
Rarity tried to protest. To plead, to beg her to stop. Before a single word could even leave her mouth, she felt the tentacle slither up her leg and towards her groin.
The leggings shifted, and the pressure from her costume was replaced by the pressure from a tentacle. Rarity moaned again, louder. Her body should have felt warm, she should have been drenched in sweat to match her panic, but she couldn’t move. Her body was like a statue. She briefly hoped that the effect meant the tentacle wouldn’t be able to get in, that her vagina would be clamped shut, but the notion vanished as the tentacle shoved itself into her pussy.
Rarity screamed. Not because the tentacle felt bad. It felt almost exactly like flesh. It was just so big. Gigantic. Even worse, more was pushing into her, her pussy being slowly yet noticeably forced open by the invasion of prehensile hair.
She screamed again, and the tentacle in her mouth responded, taking the moment her mouth was open to push deeper into her throat.
“Mmmphf!”
“Sorry, Radiance, I didn’t quite catch that.” The Mane-iac put a hoof to her ear, snickering softly. “Oh? You say you want another one? Why, I’d be happy to!”
Rarity couldn’t respond. Another tentacle had already pushed into her pussy. Her legs actually inched apart, the sheer size of the things powering through the effect of the Hair Spray Ray.
She had started to sweat now. Either the freeze effect was wearing off, or her fear and panic were just too much to contain. It was a brief relief; her body responding correctly was reassuring, even calming compared to the forced stoicism earlier.
It didn’t last. A wave of warmth crashed through her, and she moaned. Not in pain or fear, but in pleasure. Rarity heard screams and murmurs from her friends, and shouts and noises from the Mane-iac’s henchponies, but couldn’t focus long enough to understand them. Every thrust from the tentacles sent another wave of heat crashing through her body, and every one made it that much harder to think about anything else.
She could feel tears leaking down her face, she could hear the Mane-iac’s laughter echoing across the room, but those were secondary to the tentacles rubbing against her insides, pressing against every part of her.
For a moment, her legs twitched, and she could feel her body respond when she told it to move. Another thrust, and another, and she found herself telling her body to match them, to push backwards as the tentacles pushed forwards. It was too late for escape. She couldn’t break free of all these restraints even with control of her limbs. Better to enjoy it.
That made sense.
Rarity pushed herself onto the tentacle again and she felt her body shudder. Her muscles clenched and she moaned, screamed, whined into the tentacle in her mouth. The orgasm felt incredible. Her legs curled up and her neck arched back, the effect of the spray shattering in time with her scream.
The Mane-iac laughed. “Oh my, how theatric! And they tell me I overact!” She latched onto the cage, now suspended high above the floor. She pulled herself up with one tentacle, flung the top open with another, and dropped Rarity’s limp body in with the rest. There was a distinct, wet pop as the tentcales slid out of her costume. The material snapped back into place easily. The only sign it had ever been any different was the various dark splotches on it.
Rarity slumped onto the ground without any resistance. The only sound that came from her from heavy, deep breaths.
“Quite nice, Radiance. We’ll have to do this again sometime!” The Mane-iac laughed, and then turned to her doomsday cannon. “And just in time for the main event, too!”
