Vaginal sex

Ms Kyoto and Professor Lex walked into the room where Rocketgirl lay limp on the bed. She hadn't moved at all since Ms Kyoto left her there brainless the day before. "Wow, you weren't kidding," Professor Lex said. "You really did a number on her."

He snapped his fingers in front of Rocketgirl's eyes, on either side of her head. "Yoo-hoo, Rocketgirl. Do you remember me? It's your old enemy, Professor Lex."

Rocketgirl gave no sign of recognition, nor even of registering his presence.

"Like I said before, she won't remember you," Ms Kyoto remarked. "She knows she used to be Rocketgirl, but I'm the only enemy she'll remember. She knows exactly what I've done to her but she doesn't remember anything else about her former life."

"Hmph. Pity," sighed Professor Lex. "But after everything she put me through, this will still be very satisfying." He began undoing his trousers.

"Easy, fella. Not until I leave the room. I may enjoy causing her downfall, but I don't need to see your naked body. You disgust me. You're only here because we've got a common goal. Speaking of which, did you remember to eat the nodule I gave you?"

"Twenty three hours and...," he checked his watch, "...fifty-eight minutes ago."

"Perfect. Now remember, it will feel different from a normal orgasm because you won't be ejaculating semen. If for any reason you think you're about to ejaculate semen, pull out. We can't risk impregnating her before she has a brain."

"Yeah, yeah, whatever. Just leave me alone so I can fuck her already."

Ms Kyoto grabbed Professor Lex's cock through his pants and massaged delicately. He began to grow hard. "Go get her, big guy." Her hand dropped from his penis and she left the room.

Professor Lex ripped off his clothes and threw himself atop Rocketgirl. "This is for all those times you meddled with my research," he said, thrusting his hard cock into her limp pussy.

He pumped in and out of his gorgeous but languid nemesis, turning himself on by staring at her blank face and thinking of her future as described by Ms Kyoto. That the woman who'd made his life hell would be robbed of her spirit, her superpowers, her wits, and reduced to infinite sexual degradation at the hands of another woman -- a scientific colleague of Lex's -- was incredibly satisfying. He stared down at the former heroine's blank face and imagined her writhing and protesting. He smiled, then his eyes clenched shut and he felt a tingling sensation.

The climax that overtook him was unlike any he'd experienced before. He felt a long, continuous ejaculation of a gelatinous substance. When it passed, he knew the nodule had been injected into Rocketgirl. He pulled out, patted her cheek, dressed, and knocked on the door.

The two villains exchanged a few words, then Ms Kyoto's face hovered above Rocketgirl's. The heroine convulsed and spasmed. She writhed from the midsection, her abdomen rolling left and right, up and down. Her eyes blinked, her mouth opened and closed silently, opened and closed like a fish gasping for breath. Her limbs remained lying useless beside her on the bed.

"What you're feeling now is the first nodule of your new brain. Professor Lex injected you with it when he **** you a moment ago. Now it's wriggling its way up through your body to implant itself in your head. I'm judging from how you're writhing around that it's not the most pleasant sensation. The first piece of your brain will restore your ability to vocalize, so from here on out, whatever you're feeling should be apparent to whoever's watching. And hey," she said, pressing Rocketgirl's abdomen down with her palm and keeping the heroine pressed to the bed. "I'm sorry if it's a bit uncomfortable. Don't worry; you'll only have to endure this sensation 364 more times."

Ms Kyoto felt the involuntary spasming of Rocketgirl's hips but held firm. She thought she could even feel the nodule slithering up through Rocketgirl's body as it worked its way to her head.
