Make her orgasm as they eat her brain (DARK)

Alone, shackled to the bed with the earworm slowly devouring her brain, Rocketgirl panicked. She heaved and pulled mercilessly at her bindings, to no avail, succeeding only in bruising her wrists and ankles. With each vicious CHOMP from the invader in her skull, she screamed bloody **** and collapsed in an exhausted heap on the bed. Sweat began pooling beneath her straining body. She whipped her head frantically in frustration, unable to dislodge the nefarious bug that threatened her very existence.

After a few hours of incessant ****, Rocketgirl was surprised by a sudden, **** shift in her reaction to the earworm's bite. She still screamed in unimaginable agony every time she felt the insect bite. But as she screamed, she felt her pussy clench and moisten, and a sharp blast of ecstasy blinded her momentarily.

The earworm was causing her to orgasm.

At first she thought it was a coincidence. Her physical exertion, her exhaustion were causing her signals to get crossed. But after an orgasm accompanied a fourth bite in a row, she knew there was no mistake.

Panting, she blew hair from her face after the latest orgasm. "What...what the fuck?" she asked no one.

Her earbuds crackled and shrieked, causing her to wince. Then Ms Kyoto's unmistakable taunting voice filled her head. "Allow me to introduce the second generation of earworm, my dear Rocketgirl," she teased huskily. "I can only imagine how much it must hurt to have your brain eaten -- excruciatingly slowly -- from the inside out. Hardly a fate worthy of the great superheroine Rocketgirl. So I've decided to balance your pain with intense pleasure. The first offspring of each generation of earworm won't be an eater. It will be a stimulator. A lover, if you will. Judging by your reaction to the last few bites, it seems that first earworm has produced at least one offspring by now. That second worm isn't going to eat your brain. Instead, it's migrated to the pleasure center of your brain. Every time one of its family eats a piece of your brain, this second worm will rub your pleasure center, injecting a chemical to get all your pleasure synapses firing at once. From now on, every time one of the worms bites your brain, another one will give you an orgasm. And since each generation gives birth to a stimulator before birthing an eater, eventually all those stimulants will build up. You'll more than build up a tolerance for the worms eating your brain. You'll come to crave it. The level of pleasure you'll get from each bite will increase exponentially with each new generation of earworm. By the time the earworms have devoured all of your brain, you'll equate **** pain with **** pleasure. What's more, you'll be a blank slate, totally susceptible to me imprinting any personality I want on you. And at the root of it all, the signature defining characteristic of whoever I make you into, is your endless appetite for pleasure through pain. I'm going to make you the perfect little whore, Rocketgirl. And from now on, you'll love it. More and more, in fact."

Rocketgirl squirmed in protest. "Nnnnnno no, noooooooooooo!" she screamed. "You'll never make a whore out of -- nyyyyyyaaaaaAAAAAAAAAAAAHHH! Oh, oh, ohhhhhh, OOOOOOOOOOOOOOOO!" She squinted hard in pain, then her eyes opened wide with the crest of an orgasm as her agony turned to unbidden ecstasy. She thrust her hips up and down involuntarily as her pussy gushed love juice to join the puddle of sweat gathered on the sheets beneath her. Her sweaty body fell with a light *squish* into the soupy mess as she panted to gather her wits.

"You're welcome, Rocketgirl," Ms Kyoto taunted through the earbuds. "Enjoy your new life. It's only just begun."
