Slowly losing her mind (DARK)

For days, Rocketgirl struggled against the growing pain in her skull and the unyielding shackles keeping her bound to the bed. Distracted by her throbbing brain and frequent orgasms, she was unable to sleep. Exhausted, her only respite were the increasingly welcome climaxes -- and with more worms injecting chemicals to her pleasure center, each climax was more powerful than the last. Much as she relished these distractions, she felt ashamed after each orgasm, knowing they were bringing her closer to literally losing her mind -- and her identity.

From time to time, Ms Kyoto would come into the room and place the Mind Sifter on Melissa's head. "Just want to see how far along you are, my love," she said the first time. Each time, without even looking at her subject, she'd tap on a tablet, causing a fresh agony to sweep through Rocketgirl's head briefly. The artificially induced agony from the Mind Sifter would temporarily overwhelm the constant thrumming pain caused by the earworms. But inevitably, after mere seconds, Rocketgirl was released back to the swelling pain and throbbing pleasure brought on by her invaders.

Scanning the Mind Sifter's readouts on her tablet, Ms Kyoto would make meaningless observations. "Yes," "Good," "Right then," "Fine, fine," "All right." She'd hug the tablet to her chest, retrieve the Mind Sifter, and, making eye contact with the struggling heroine for the first time, say simply, "Bye" before turning and leaving the room.

But the last time she got her readouts, Ms Kyoto's stare lingered. "Won't be long now," she said, and Rocketgirl felt her pulse quicken with fear.

Rocketgirl was taken aback now to see Ms Kyoto walk in wheeling a cart with some sort of machinery on it. A large plastic box, it was hollowed out from one side, with rings inside the hole. Ms Kyoto lifted the contraption, placing it on the bed. She lifted Rocketgirl's head and pushed the machine behind the heroine, then gently lowered Melissa's aching head into the creviced side of the machine. She slowly rocked the machine back and forth so Melissa's head went further and further inside the box. When Ms Kyoto plugged the machine in, Melissa saw a ring of light turn on surrounding her head.

"This is an MRI machine, Rocketgirl." Straining her neck, Melissa could see Ms Kyoto at the foot of the bed. "Your brain must be in an incredible amount of pain right now. There's no need to subject you to the Mind Sifter again. But I do want to see what's going on inside that lovely head of yours."

She walked back to the head of the bed, disappearing from Melissa's sight. Melissa heard her flip a switch and press a few buttons. The ring of light began to spin and the machine emitted a dull drone.

"This won't hurt a bit!" Ms Kyoto shouted over the noise before hitting another button. The light flashed repeatedly as it spun faster. As annoying as the light was, Rocketgirl only screamed because the worms kept biting her brain. Her body quaked with a millionth orgasm.

"Hold still, you silly goose!" Ms Kyoto teased. "The more you move, the longer this will take."

"I c-...I can't," Rocketgirl stammered, pushing through her pain. "Y-you've m...you've made me this way. But you can...you can make it stop. You can remove those...those earworms and...and let me go."

"Not today, Rocketgirl," Ms Kyoto replied. "Not when we're so close to your breakthrough."

The machine stopped whirring. The ring of light faded out. Melissa heard it printing something, then heard Ms Kyoto rustle the printout.

"Oh, exquisite. Oh, outstanding!" Ms Kyoto exclaimed. She yanked the MRI machine from the bed. Melissa's head banged on the lip of the machine before falling back to the bed. But the pain from the back of her head barely registered compared to the constant throbbing ache within.

"I think you'll want to see this," Ms Kyoto said, holding the MRI printout up above Rocketgirl's face.
