Rachel awoke on the couch in Wendy’s living room. As her systems came online, she reached to the back of her neck, and felt the latest upgrade to her nervous system. Two metal holes, about a quarter-inch apart, one above the other. They were cold and empty.
“Ah,” came Wendy’s familiar voice from behind her instrument. “You’re awake, my dear! Wonderful! Let’s make sure everything’s okay before we test out your new upgrade. Systems check.”
Rachel sat bolt upright, and her eyes rolled back briefly in their sockets, as her cybernetic systems ran a diagnostic. No errors.
“Green light,” said Rachel, relaxing her body.
Wendy smiled. “Wonderful! If you’re ready, my dear, we can run some tests.”
Rachel touched the holes in the back of her neck again. Two one-eighth-inch monophonic audio sockets, one for the left audio channel, one for the right—each of which had been wired directly into her central nervous system. Rachel looked up at Wendy, still idly touching the new upgrade, and smiled. “I’m ready.”
Wendy came over with a pair of long audio cables, and sat down next to Rachel on the couch. She let their length dangle over Rachel’s bare legs, one cable brushing the small bulge in her panties. “Hm... do you want to plug them in, or should I?”
Rachel thought for a moment. The anticipation of what Wendy was about to try was giving her a warm, tingling sensation already. She just needed that connection, but it didn’t feel right to just take the cables and plug herself in.
An idea came to her. “How about you plug one in, and I’ll plug in the other.”
“A lovely idea, my dear,” said Wendy. She brushed aside Rachel’s bangs and placed a gentle kiss on her forehead before handing her a cable. “I’ll put mine in the top plug, you put yours in the bottom, okay?”
Rachel nodded, and brought the plug of the cable up to the back of her neck. Wendy placed her right hand on the right side of Rachel’s neck, and handled the plug with her left. Together, they inserted the cables into Rachel’s waiting sockets. The plugs made a metallic click as they connected.
All at once, Rachel felt a warm, quiet vibration throghout her body. Not what she had expected at all, but not unpleasant either.
“I’m not feeling much of anything,” she said. “Just a warm sensation, kind of a hum.”
“That’s because I haven’t switched on any of the oscillators,” Wendy said. “You’re just feeling the power supply and the control voltage. Just you wait until I turn everything on!”
With that, Wendy arose from the couch, and returned to her usual position behind the instrument. Rachel had sat here and watched Wendy serenade her with wonderful electronic sounds many times. Wendy’s dextrous hands could spring forth such wonderful music. Rachel had tried to figure out the instrument, a byzantine mix of wires, sockets, and knobs, but to no avail. She understood the general principle, of course: an electrical signal of waveform, filtered and modulated, but the way it came together as a whole had eluded her. No matter, she could still appreciate the results.
And today she would appreciate them in a whole new way.
Wendy pressed a button, and Rachel’s body began to vibrate with sensation. She could hear a low rumbling sound over Wendy’s speakers, but she could feel it as well, through every nerve in her body.
“We’ll take it slow to start,” Wendy said. “Pure tones. Just a low-frequency sine wave for now. Nothing too intense, nothing with too many harmonics.”
Rachel nodded, and closed her eyes. The sensation was wonderful, so warm.
“Now, whatever I do, respond as you must, but do not touch yourself,” Wendy said. “I need to see how you respond to the instrument, not any other sensation.” With that, Wendy reached for a knob and slowly turned it. The warm, gentle sensation in Rachel’s body grew hotter and stronger, then went down to a quieter sensation. As Wendy rotated the knob higher again, Rachel began to shake and moan.
“Oh, you like that! Now, let me see...” Wendy dialed the knob back, and Rachel opened her eyes to see Wendy plugging in a couple of cables. The sensation stopped, and then resumed.
“I’ve hooked up a sequencer that’ll adjust the frequency at each step.” Wendy made some adjustments, and Rachel felt a gentle rising and falling of the sensations on her body... warm, then slowly getting hot, then slowly back down to warm again. It felt a bit like a massage, but from within her body.
Wendy turned another knob, and the rising and falling came faster. Rachel began to writhe on the couch, and moan with pleasure. The sensations were strong, but not too intense. Rachel laid down on her side, and closed her eyes, moaning softly. Wendy looked at her with a smile, and began to plug more cables into the instrument. Rachel looked up at Wendy with curious eyes, and Wendy placed a finger to her own lips, then shook her head. “Patience, my pet,” she said.
All at once, the sensations changed. Rather than gentle rhythmic pulses, rising and falling, Rachel now felt them come in sharp, piercing stabs, like needles under the surface of her skin. Rachel yelped and writhed, as if she was trying to leap from her own skin.
“Oh, my!” said Wendy, “Is that too intense for you, dear?” She turned down the amplifier, to give Rachel a chance to respond.
“Maybe... a little...” Rachel said, trying to catch her breath.
Wendy said nothing, but turned the amplifier back up, though not quite as high as before. “That’s... aaah! That’s... better!” Rachel said, as she gripped the fabric of the sofa cushions. Wendy turned some dials, and the needle-like sensations faded to almost nothing. Rachel released her grip on the couch cushions. She could feel something building in her nerves, something slowly rising in intensity. She shut her eyes and moaned as the pressure of sensation built up and when it peaked, she let out a yelp and a soft moan, as the sensations fell off. Then the building and rising returned. The buildup was slow, but the peak was even higher.
Wendy adjusted the knobs on the instrument, and Rachel felt the rising and peaking come just a little faster and a little stronger this time. She moaned and writhed against the couch, bucking her hips slightly as the wave peaked in her nervous system. At each peak, the moans would turn into a squeal of pleasure, and Wendy took this moment to touch herself as she watched her toy.
In her arousal, Wendy had a wonderful thought, and started to plug a few more cables into the instrument. This time, she hooked up a second oscillator, adding a sawtooth wave to the rising and falling sequence. Rachel could feel the rumbling sensation deep in her body, a throbbing rhythm to offset the peaks of the waves. How wonderful, how strong, how magical it was to feel Wendy’s sounds in her body.
Wendy stepped from the instrument, and sat down next to Rachel’s moaning, writing body. She wanted to see what her work was doing to her toy up close. Rachel could feel Wendy’s body near hers, even through the electric sensations running through her nerves, and rolled onto her back. Rachel looked up at Wendy with a mix of awe and desire in her eyes, and Wendy looked down at her with a wry smile on her face.
There was a wet spot on the bulge of Rachel’s underwear. Wendy smiled. She wanted to touch it, even take off her little toy’s underpants, and suck her swollen cock until the poor girl’s body couldn’t take any more. No, that would have to wait. There was still more testing she needed to do. If the poor girl made a mess of herself in the process, well, that was the risk they’d have to take. Wendy stood up, kissed Rachel deeply as she writhed, and returned to the instrument.
Wendy adjusted the knobs, returning the sine wave to a more gentle, constant sensation. Before shaping the wave form any more, it was time to try some filters and modulation. Rachel sat up, looking over at Wendy, who was staring down at the instrument with a look of great concentration on her face.
“Darling,” Wendy said, “it’s going to take a little time and fiddling to get the sounds I want to try. If you’d prefer, I can unplug you from here.”
Rachel thought for a moment, and stretched her arms and legs. The sensations she had felt from Wendy’s instrument were wonderful, but she knew that when Wendy needed to make the right sound, it could take a lot of trial, error, and unpleasantness. There had been many nights when she heard Wendy fighting with the instrument, hearing unpleasant sounds escaping through Wendy’s headphones. She also had no idea how those sounds would feel in her body, however, and the curiosity was overwhelming.
“Leave me plugged in,” she said. “I want to feel everything.”
Wendy laughed, and clasped her hands. “Oh, you jewel! I knew there was a reason I picked you! That said...” Wendy turned off the instrument, and walked over to Rachel. “Let’s take a little break first, hm? You look like you could use some water, at the very least.” Rachel nodded, missing the warm sensations in her body, but agreeing that she could use a breather.
A glass of water, and some gentle hugs, kisses, and pats on the head from Wendy later, Rachel jumped up from the couch as Wendy switched the instrument back on. Once her body recognized the sensations, she sat back down, and relaxed.
“I’ll check in as I go,” said Wendy. “You tell me if you’re too uncomfortable.” Rachel nodded. “Green light?” asked Wendy.
“Green light.” said Rachel, and Wendy went to work. In her mind, Wendy was already hearing the sounds—a sequenced sawtooth bass rhythm on the low end, something deep and resonant. Over that, she could layer a sharp, plucked synth, played by hand. She pictured Rachel writhing with the sharp jabs of needle-like sounds, especially the high notes. Getting everything right might take a little time, but Wendy was going to keep it simple. Tonight wasn’t a night for synthetic symphonies. Tonight called for something more direct, something to target the body more than the mind.
Wendy started with drums, something she hadn’t tested on Rachel yet. She programmed a simple beat into the instrument’s drum machine, a four-to-the-floor kick drum with some high-hats, and hit play. Rachel’s eyes opened wide, and she began to twitch and jerk to the beat, and from the look on her face, Wendy could tell it wasn’t just involuntary.
“If you feel the need to move, darling,” Wendy said, “you’re more than welcome.”
Rachel tapped her right leg to the beat, but remained on the couch, as Wendy turned her attention to the bass sound. She set an oscillator to a sawtooth wave, and that to a filter which would modulate the sound. At first, it was rough, and harsh, and Rachel groaned as the signals went into her body. Her leg stopped tapping, and she wriggled and writhed on the couch, breathing hard.
Wendy bit the inside of her cheek, and with intense concentration, adjusted the knobs on the filter module until the sound took on a deep, resonant sound, like that of a low, plucked string. Satisfied, she programmed a rhythm into the instrument’s sequencer, and routed the oscillator’s output into it. Rachel’s discomfort faded, though she continued to writhe and wriggle, the look on her face made it clear that this was a much more pleasurable sensation. A gentle “aaah” escaped from Rachel’s lips.
As Rachel continued to moan and writhe, Wendy could feel herself getting turned on as well. Watching her little cyborg pet moan from the sounds her hands summoned was intoxicating. She needed to concentrate if she wanted complete control over her instrument, and her throbbing clit was not helping. Wendy knew she had to power through it—to touch herself now would only wreck this lovely experiment. She gritted her teeth, and grabbed a handful of patch cables.
Working quickly, Wendy connected up her lead patch—an oscillator into a filter, and an envelope set to what she hoped would create a sharp, stabbing lead, with a gentle decay, something she hoped would feel to Rachel like a Violet Wand along her skin. The envelope was then connected to the instrument’s keyboard controller. Wendy pressed a key, and Rachel gasped, and collapsed onto the couch.
“Fuck! Fuck! Yellow light! Yellow—fuck—light!” she said.
“Fuck!” Wendy muttered, and tried to adjust her patch. The rhythm of the music was getting to her, along with Rachel’s movements and moans. As Rachel sat back up, Wendy adjusted the oscillator frequency down, hoping to keep the same wave shape, just less intense. She closed her eyes, and pressed a key on the controller. Rachel yelped, but when Wendy opened her eyes, she was still upright.
“Green... light...” said Rachel. “Green... Fuck!”
Wendy was now back in control, playing a melody with her keyboard. The stabbing synthesizers contrasted with the high-pitched yelps and moans from Rachel, as she rhythmically wriggled on the couch. She grabbed at the cushions, and bucked her hips, but like a good toy, kept her hands off of herself.
Wendy couldn’t say the same for herself, and pinched a nipple through her blouse with her free hand as she watched the display she was orchestrating. She wished she could take the keyboard, and bring it over to the couch, stimulating her cyborg toy with one hand, playing a melody with the other.
An idea came to her. If Wendy couldn’t bring her instrument to the toy, there was more than enough cable to bring the toy to her. Wendy grasped the audio leads running from the amplifier to Rachel’s neck and tugged on them, just hard enough to get the girl’s attention. Rachel’s eyes opened, and Wendy pulled again, gesturing with a finger for Rachel to approach.
Wendy had let Rachel play with the instrument before. Her curiosity was appealing—part of why she made such a wonderful toy—but when Wendy was performing, she preferred to have the stage to herself. Rachel gave Wendy as curious of a look as she could manage through the stimulation, and Wendy pulled the cables again. Rachel got to her feet, and made her way behind the instrument, stopping at one point to fall to her knees in a mix of pleasure and pain at the end of a bar of music.
Once at the instrument, Wendy grasped Rachel, and kissed her with passion and force. She could feel the electricity flowing through Rachel’s skin as she held her close, tongues in each others mouths. She almost wanted an audio input of her own, but she did have a place Rachel could plug in to her.
Wendy pulled away, and played a figure on the keyboard, bringing Rachel to her knees again, shivering and moaning in near orgasmic bliss. The bulge in her panties was straining the cotton fabric, just what Wendy loved to see. As Rachel writhed, Wendy played the keyboard with one hand, and began to unbutton her blouse with the other. Wendy switched hands as needed, and turned her attention to her skirt. This was easier, and with the pull of a zipper, Wendy stood before her kneeling, quivering toy in only a pair of black panties.
Letting the keyboard go again, Wendy kneeled down and placed her right hand on Rachel’s chin in a firm, but gentle grip. With her left hand on Rachel’s arm, she gently lifted the toy up to standing, bracing her in case her legs buckled again. They shook, but held the girl upright. Wendy nuzzled the bulging crotch of Rachel’s underwear, flicking her tongue against the dark wet spot at the peak. Rachel yelped in pleasure. Wendy softly brushed the bulge with the back of her hand, and pulled the girl’s panties down, releasing Rachel’s hard, dripping cock.
“Oh, my sweet, sweet jewel, I think this experiment is quite a success,” Wendy said, and kissed Rachel’s glans, and flicked her tongue on Rachel’s frenulum. The poor girl let out a deep, pleasurable moan, and her knees bent but did not buckle.
Wendy stood up, placed her hands on Rachel’s hips, and moved her to a position where she would be directly behind Wendy as she controlled the instrument. Desire rose within her, focused on her nipples, and her clit. There was one thing she wanted to try more than anything, and she adjusted the drum machine and sequencer, in preparation. The speakers roared with a thudding, undulating rhythm of fuckbeats. Wendy then reached into the cabinet where she kept her patch cables, and pulled out a bottle she kept handy for the nights of passion she and Rachel had shared after serenading the toy with her symphonies.
It was time. Wendy was ready, and one look at Rachel was enough to confirm that she was as well. Wendy lowered her panties, and stepped out them, kicking them to the side. She poured a generous portion of lube on to Rachel’s erection, and stroked it until her cock was generously coated. Wendy couldn’t help but use her nimble fingers to stroke Rachel’s sensitive little sack, and ran a finger around the edge of her anus. Rachel’s moaning rose and fall in time with the music.
At last, Wendy turned back to the instrument, and bent her knees. The opening of her neovagina was in line with Rachel’s cock. Wendy knew her toy would know exactly what to do now.
Rachel rested a soft hand on Wendy’s waist, and slid her cock into Wendy’s slit. Now, it was Wendy’s turn to gasp and quiver, and she let out a long, sensual moan of pleasure. Steeling herself now, Wendy reached for a knob and turned up the volume of the bass rhythm, and then turned another knob on the instrument.
Slowly, the tempo of the music began to rise, and in turn, so did Rachel’s movements. Gripping Wendy tight, Rachel felt an uncontrollable urge to thrust deep into Wendy’s body.
“Good... girl...” Wendy said, barely maintaining her hold on the instrument and its controls. She turned the knob controlling the tempo down, and then back up, testing to see which intensity felt the best for both of them. With the tempo slower, Wendy could play the keyboard, and with each sharp stab, Rachel’s body shook, creating sympathetic vibrations within Wendy’s body that made them both howl in pleasure. Wendy almost wished she had a microphone so their sounds of pleasure could be amplified and mixed into the music.
Instead, now, Wendy turned the knob controlling the tempo of the rhythm, slowly cranking it upwards. Wendy was no longer concerned about the melody and the keyboard now. As Wendy turned the dial higher, she felt Rachel’s grip on her waist tighten, and her thrusting grow more intense.
Rachel shouted, and collapsed, pulling Wendy away from the instrument, and down on top of her, her hips still thrusting. Wendy forgot about the instrument, forgot about the music, and rode the waves of Rachel’s thrusting until her whole body shook and went limp. Rachel followed soon after, gasping and moaning as she came, her body still shaking and thrusting to the signals in her nerves.
Entwined on the floor, Wendy reached up to Rachel’s neck, and pulled her head close. She kissed her toy, thrusting her tongue deep inside Rachel’s mouth, and unplugging the audio leads from her inputs. Rachel fell limp and closed her eyes, her breathing shallow and short. Wendy held her tight, brushing the sweat-soaked hair from her forehead until her body calmed down.
“Systems check,” Wendy whispered into Rachel’s ear.
After a moment, Rachel gasped. She opened her eyes, and rolled over to face Wendy. She whispered in return, “Green light.”
