Alters Rocketgirl's powers

"I think I'll start with that pesky heroine Rocketgirl," Ms Kyoto said, her voice dripping menace. "She's been a thorn in the side of me and the rest of villainkind for years. Next to her, Melissa is a cakewalk."

Exhausted from her ordeal of the last few days, Melissa teetered on the brink of sleep. She was vaguely aware of Ms Kyoto's threat but couldn't muster the energy to fight. Before she knew it, Ms Kyoto had clamped a damp cloth over her face. The scent of chloroform overwhelmed her. Her eyes rolled back in her head and she was out within seconds.

Sometime later, Melissa awoke manacled to a hospital bed. She wore a cheap knockoff of her old Rocketgirl togs, a stylized "V" in the place of her traditional "R" logo. She was connected to an EKG and an IV was providing her a steady infusion of...she didn't know what.

"Wakey, wakey, Roketgirl." Melissa heard Ms Kyoto's voice through the earbuds several seconds before Ms Kyoto actually entered the room. The villainess's hands were stuffed into the pockets of a crisp white lab coat. "I'm glad to see you're recovering so quickly. It means your body has adapted faster than I anticipated."

"Adapt-- *cough* *cough*" Melissa's throat was sore and dry. Ms Kyoto popped a straw into a juice box and held it up to Melissa's lips. The heroine glowered at her captor, but craned her head forward to take the straw between her chapped lips. She sucked eagerly until the box was completely drained.

"Atta girl," Ms Kyoto said, caressing the heroine's cheek as she pulled the juice box away. "As I was saying, the virus must have completely overtaken you by now, and you're only awake because your body no longer needs to focus all its energy on developing antigens."

"Virus? Antigens?" Melissa sat bolt upright. "GAAAH!" she winced in pain, the manacles pulling her back down to the bed.

"Yes. You see, while you were out, I infected you with a virus I developed. This IV drip is continuing to pump it into your body, but it seems that's no longer necessary." Ms Kyoto ripped the needle out of Melissa's arm, causing the heroine to howl sharply in pain.

"The virus has already taken its toll on you. But I'm sure you have nothing to fear. Whatever I've done to you can be no match for the superpowers of the great Rocketgirl, right?"

"I think it, you say it," Melissa quipped. "But you're such a proud woman. Why don't you tell me about the virus anyway?"

Ms Kyoto pulled a hot pink bottle from her lab coat pocket and unscrewed a dropper from it. She dripped three hot pink drops on each of the four manacles holding Rocketgirl to the bed. The manacles began to hiss and smoke where the hot pink fluid touched them. Slowly but surely, holes were burning into the thick material.

"No, thanks. You'll figure it out soon enough on your own. But I will give you a hint." Ms Kyoto smiled, depositing the hot pink bottle in her lab coat. "In sixty seconds, your manacles will break open. I'll be long gone before that happens, but you'll be free to go. Might I suggest you use your superspeed to get as far away from this place as possible. Before I change my mind."

Ms Kyoto grinned mischievously, turned on her heel, and strode from the room.

Melissa sat utterly confused as the manacles burned through. Why would Ms Kyoto go to the trouble of cloning her and sending an impostor to take over her life if she was just going to turn around and let Melissa free a few hours later? And what was all this business about a virus? Was Ms Kyoto making all that up?

Rocketgirl would have plenty of time to figure it all out later. Now, all four manacles simultaneously broke open, freeing the hopeful heroine. Rocketgirl ripped the EKG sensors from her body, swung her legs over the side of the bed, and stood up. Summoning the power of her superspeed, she took off sprinting.

"Wwwwwwwuuuuuuhhhhh????!!" Melissa exclaimed in excitement and confusion. She looked down. Her legs hadn't moved. She was planted beside the hospital bed where she'd stood up a moment ago. She felt a rapid thrumming in her loins and saw the crotch of her knockoff uniform vibrating in a blinding blur.

Rocketgirl swallowed, blinked, and craned her head back. She moaned sensually. Her pussy clamped open and shut, open and shut in rapid succession, eager to be filled. Her clit throbbed and her labia soaked through her panties, dripping onto the floor. Overcome by sexual excitement, Rocketgirl's knees wobbled and she tumbled to the floor.

Ms Kyoto's throaty laughter filled Rocketgirl's ears. The villainess sauntered back into the room, slowly applauding the heroine's pathetic display.

"What did...what did you do to me?" Rocketgirl panted, staring up at her nemesis.

"Frankly, I'm surprised it worked," Ms Kyoto said modestly, touching a hand to her chest. "I've never altered the human genome before. But you were a worthy challenge, and I must say the results are better than I could have possibly dreamed."

"What are you talking about?" Rocketgirl demanded, gradually recovering from the overload of sensations in her pussy.

"You mean you haven't figured it out yet? My, you really are a dim bulb. It's simple, my dear. I isolated the gene that gave you your superpowers. The virus I injected you with altered that gene, replacing your superpowers with a special feature of my very own design. Now, instead of having superspeed, you've been gifted with a much more...intimate superpower. All the energy and speed that used to go into your legs now goes into vibrating every muscle connected to your vagina. Your clitoris, your labia, your G-spot, your vaginal walls -- all of them vibrate with an incredible, superhuman speed."

"But I'm a superheroine," Rocketgirl stammered.

"Not anymore. You're no longer Rocketgirl. Now...you're Vibrapussy."

At the sound of the word Vibrapussy, Melissa once again felt the overwhelming sensation of high speed vibrations emanating from her loins. "Ohhh!" she moaned, her hands almost involuntarily creeping to her crotch, where she began to gently massage her clit. After a few seconds, she caught herself, throwing her arms out to her sides to prevent herself from contributing to her own humiliation. She sobbed as she realized the extent of her capitulation.

"Oh, sweetie, it's okay!" Ms Kyoto said mock soothingly. She knelt down and cupped the former heroine's face in her hands, lifting it so the heroine had to look directly into her eyes. "It's okay! I made the virus incredibly complicated. You just experienced one of your triggers, that's all."

"T...t-triggers?" Melissa wailed. She didn't like the sound of this at all.

"Yes. Basically, there are several things that will set yoru pussy to vibrating. One of them, the first one you experienced, is when you try to summon your superpowers. But that's a bit obvious, and now that you know, I suspect you won't be trying to summon your superpowers again anytime soon. So I had to throw in several other triggers, as well. One of them is when you hear your new name..."

"No..." the former Rocketgirl said, shaking her head rapidly.

"What's that name again?"

"No," Melissa repeated, more insistently now.

"It's not Rocketgirl..."

"No, please, don't say it!"

Ms Kyoto traced the "V" on Rocketgirl's thin costume, her finger delicately teasing the former heroine's tits. "It starts with a V..."

Melissa swallowed hard, and a single tear ran from each of her eyes. She knew what was coming next.

Ms Kyoto's lips brushed Rocketgirl's ear. As the villainess exhaled, her sultry whisper tickled her captive's ear. "Vibrapussy."

This time, the buildup of sexual energy was too much. Melissa's whole body quaked violently, slapping against Ms Kyoto as her pussy gushed and vibrated rapidly. Then, utterly spent, she collapsed in a heap on Ms Kyoto's shoulder.

"I'm so proud of you, Vibrapussy," Ms Kyoto said, catching Melissa off-guard. The heroine shuddered and spasmed, her pussy clenching over itself rapidly as the new trigger overlapped with the final crest of the preceding one.

Ms Kyoto pushed the heroine off her and held her by the shoulders. She leaned in and found Melissa's lips with her own. She kissed the orgasming ex-superheroine once, twice, three times. Sensing Melissa's waning orgasm, Ms Kyoto darted her tongue into Melissa's mouth on the fourth kiss. Her tongue wetly petted Melissa's and wagged back and forth over the roof of her mouth.

Melissa realized too late that French kissing was another trigger. Her pussy vibrated faster and faster, over and over as Ms Kyoto continued to lap at the inside of her mouth.

Too weak to pull away, Melissa could only ride out the onslaught of vibrations and orgasms inflicted on her by Ms Kyoto's relentless triggering of her new "superpower." Finally, after several minutes, Ms Kyoto pulled away. Melissa collapsed in a heap, desperately panting air into her overworked lungs.

"Please...no more...no more...triggers...no more...please..."

Ms Kyoto regarded her with a relaxed smile. "Oh, there are plenty more triggers, Melissa. But you'll just have to discover them all in good time. But first, there's one more thing I want to do with your new name."

Ms Kyoto reached into her lab coat pocket and pulled out her Mind Sifter. Knowing Melissa would recognize the instrument that began her downfall, Ms Kyoto waved it in front of the glassy-eyed ex-heroine's face, holding it there long enough for Melissa to focus on it and register what it was.

Melissa's eyes suddenly widened with recognition. "No! Not the Mind Sifter -- not again!" But so weakened was she by her orgasms that she couldn't prevent Ms Kyoto from affixing the device to her forehead.

Ms Kyoto pulled a remote from her pocket. "Since you're no longer Rocketgirl, I thought it only appropriate we replace all references to Rocketgirl in your head with references to your new secret identity:..."

"No, please God no, don't say it."

"...Vibrapussy," Ms Kyoto said as she pressed a button on the remote.

At once two things happened. Melissa's pussy vibrated rapidly as more orgasms built within her as the trigger word affected her body. And the Mind Sifter went to work on her mind.

"NNNNNYYYYYYAAAAAAAAAAAAAHHHHHH!" Melissa screamed, pulling her hands up to her temples. Her head bounced rapidly back and forth between her clenched hands as she struggled with the intense pain searing through her brain as the Mind Sifter altered her psyche.

One by one, every reference to Rocketgirl in Melissa's mind was replaced by a reference to Vibrapussy. Subconsciously, Melissa knew this would be bad. She would still think of herself as two people: Melissa by day and a brave superheroine by night. But the superheroine would no longer be Rocketgirl. Even in her memories, she would think of herself not as Rocketgirl...but as Vibrapussy. As the last of her Rocketgirl thoughts was overwritten, she shuddered with fear that even passing thoughts of her superheroine career would cause her pussy to vibrate at superspeed, sending her to orgasm. Could she even function as a superheroine after this?

Melissa's head stopped vibrating and her eyes rolled up, her head hitting the floor with a loud THUNK at exactly the moment the last of her orgasms subsided. Ms Kyoto reached down to collect the Mind Sifter. She chuckled menacingly, as though she knew the truth of Melissa's deepest fear.

Ms Kyoto couldn't wait to see if even the thought of being a superheroine would send Melissa vibrating into orgasm.
