Interlude: building device 2

"I was so inspired by watching you **** our guest," Hannah said, "that I decided to put my experiment on hold. Instead, I'm preparing the audio for her earbuds. I've got the perfect high-pitch frequency, and I've started overlaying the background sounds the recorder picked up of us fucking her a little while ago. Now I'm going to add some more direct vocal stimulants. Do you want to prepare the molds while she's still out of it?"

Nicole beamed at her daughter. "What a brilliant idea," she said. She tapped the phone again, restarting the strobe light effect in Rocketgirl's contact lenses. The heroine's body twitched again on the table. "Now that we know it won't kill her, I'll leave it on while I take the molds to keep her distracted. Be right back." Nicole went upstairs.

Hannah pulled a microphone up to her lips and hit a switch. She began licking and kissing the microphone, then moaning. She began fingering her pussy, and let the microphone pick up the sounds of her growing arousal and ultimate orgasm.

"At least put a sock on the door," Nicole said as she came back down the stairs.

"Almost done," Hannah replied, then threw her voice down an octave to make sensual compliments of Rocketgirl's hot body.

While Hannah continued to make love to the microphone, Nicole snapped on a pair of latex gloves, turned Rocketgirl's head to rest gently on its right cheek, and opened a jar of plaster. She scooped up a handful and began petting it into Melissa's left ear. She was careful not to let it sink too deep; she'd need to be able to pry it out once it hardened. But she tenderly pinched and patted it into every crevice and corner of the exposed parts of Melissa's ear. Then she scooped out more plaster and layered it over and around Melissa's ear, creating a cast in a large bulbous shape completely framing the heroine's ear. She set a timer and waited for it to dry.

Melissa was vaguely aware of something happening nearby. She'd faintly heard Hannah's sensual moaning sounds, muffled moreso now that there was something blocking her ear. She'd felt her head being manipulated but was helpless to struggle against it, the strobe lights having given her a mammoth migraine. She could only lie waiting for her captors to decide to let up their ****, and hope whatever came next wasn't worse.

After a few minutes, Nicole peeled Melissa's ear out of the cast. The heroine grunted absentmindedly a few times as her ear was prodded and squeezed. Nicole placed the mold on a nearby table, then snapped on a fresh pair of latex gloves, turned Melissa's head to rest on its left cheek, and repeated the casting process with Melissa's right ear.

Around the time Nicole finished peeling the right ear mold off Rocketgirl's head, Hannah came over to hand her a flash drive. "The audio files are ready," she said. "Could you give me control of the app while you're making the earbuds? I want to play with her a bit."

Nicole looked at her skeptically. "Are you sure you don't want to get started on your formulas?"

Hannah smiled. "I think I can do both. Besides, she's pretty far gone. If I switched off her strobe lights now, she may not even be fully recovered for a few hours."

"That's certainly true," Nicole replied. She tapped a few controls in the app, and Hannah's phone pinged.

"Excellent. Thanks," she lowered the strobe to about 60 flashes per second, then walked back to the lab table. "I'll get to work on these while she's coming around. Good luck up there. Let me know if you need me."

Nicole took the ear molds and flash drive and walked upstairs.
