David drummed his fingers on the table, his knee bounced up and down. He looked over his preparations one last time: fresh flowers, homemade dinner, a crackling fireplace… was this too much? Maybe. Would it even matter if things played out the way he’d intended? Maybe not.
If this worked how he hoped, he’d be able to do the impossible; he’d be able to sleep with Christine, his best friend since high college. He wondered back to her many rejections over the years, some were gentle and some left him broken hearted for months after. In the end, she was the cute girl next door with a gorgeous smile and a progressively more rocking body the longer he’d known her. Not supermodel skinny but with full, flowing curves around her ass and chest, strong thighs and a toned layer of muscle underneath her soft exterior.
He jumped, pulled from his dream, as the lock clicked and she walked into their shared apartment, now with his touches of romance scattered about. He clicked the remote as the speakers hummed out a chill low-fidelity beat, masking other frequencies hidden underneath. She set down her coat and slumped as she looked at him.
“Come on, David,” she groaned. “This again?”
“No, no come on. This is just a friendly dinner.”
“A friendly dinner with candles and wine?”
“Not just any wine, a Meiomi Pinot Noir, your favorite.”
She paused, it’s not that they hadn’t tried to date a few times over the years, they were best friends after all and had been through a lot together. High college, puberty, school, numerous flings and flirts throughout, but there had never been a spark, at least that’s what Christine had said. No chemistry or sexual attraction, and now in their early adult life they were roommates. Totally platonic roommates. Great.
“Just one drink?” David asked.
She considered it, half listening to the music. She softly bit her lip, finally meeting David’s gaze with something a bit more mischievous in her eyes.
“Just one drink.”
David grinned.

Two days earlier.
David was day-dreaming of Christine as he typed the strings of data his lab assistant was spouting out. A short low frequency droned from the speaker of his computer.
“And how does that make you feel?”
“Um, sad. I guess?”
“On a scale of 1-10, how sad does it make you feel?”
“5? I know that’s not really high, sorry.”
David sighed, it was not very high. So far his PhD research topic had been a total bust. Looking for psychological connections between abnormal frequencies had been such an interesting topic when he’d chosen it. But now, after 5 months of half-hearted studies with no obvious connections, he’d been reduced to testing on his undergrad lab assistant.
“It’s okay, Allison, I need you to be honest if we’re going to actually prove something here.” He checked the time and the other tests remaining for today. He’d been experimenting with varying frequencies of naturally occurring sound patterns. So far the so-called “golden ratio” was a golden waste-of-time. Next he just needed to test the QRS pattern so he could go home and jack off thinking about Christine for the billionth time.
“A few more then we can head out.”
“Okay!” she squeaked.
As the tone began to play, beginning almost imperceptibly and increasing in volume David glanced over at Allison. She was timid and meek in all the methods Christine was not. A brilliant engineer who’d been glad to take on the research job he’d offered her, Allison lacked the confidence to make much of her razor-sharp intellect. Despite spending so much time in the office with her he’d never really found her very attractive. She was tall (for a woman), skinny, and her brown hair was all the time flat and straight; covering up half of her face. David didn’t know what sort of body she had due to the fact that all she ever wore was jeans and a black hoodie, concealing any feminine features she might have had.
David blinked, realizing he’d been lost in wondered once again. The sound had been playing for longer than the 15 second test and Allison was looking uncomfortable. She sat dazed, shifting in her seat, with her face bright red as she held a blank, almost worried expression.
As soon as he pressed pause, she bolted up. “I have to go!” She exclaimed before shuffling quickly to the door and out of the lab. David remained, staring at the waveform that was open on the computer, it had only been playing for about a minute.
David smiled as he typed in the notes section of the mp3 file. Requires more testing.
* * *
The next day he’d approached Allison’s desk with caution, not wanting to scare her away.
“Hey, so what was that about yesterday?”
“Oh, um, yeah. I’m sorry, that sound was really unsettling,” Allison slouched more into her hoodie so it went up to her ears, covering most of her face. David could see it was regaining it’s red sheen from yesterday.
“That’s okay, I was just hoping we could gather the data from it. Since it is the only one that’s given any kind of measurable reaction.” His finger began to tap on her desk with a bit of willing worriedness. It was true, David had been up all night thinking about the effect that the sound had had on his assistant. And as a scientist he was being honest, this did need a few more tests to prove some things out, maybe just not the way Allison had intended.
“I guess we can record the data,” she said hesitantly.
“Perfect,” David clapped his hands together. “Let’s head to the sound room.”
“Wait, can’t I just tell you here?”
David did his best “disappointed professor” look at the girl. “How about we take this as a learning opportunity and you tell me why we can’t do that?”
She sighed, looking down, “We need to control as many elements as possible to not interfere with the data collection.”
“Bingo, now let’s go.”
The sound room was an empty office in the lab that had a few comfy chairs set up and a place for David’s laptop and speaker. Unlike the main lab it had no direct view of the hallway or outside, thanks to the double set of doors.
Once they had settled inside David set everything up and began a recording so he didn’t have to worry about typing. “Tell me what you felt yesterday.”
“May 29th, when listening to waveform 491, this is Allison Smith…” she began.
“Very thorough Allison, but I already have that information typed out. I just want to know your experience.”
“Oh! Y-yeah, sorry….habit…” she paused, not wanting to proceed.
David let the silence go on, until she finally broke. “It- it made me feel warm.”
“Warm how?”
“About a 7….or 8.”
“No, Allison, what kind of warmth did waveform 491 make you feel? Explain.”
“Like,” she paused again, looking for the right words. “A warmth deep in my body, a very natural one, it made me uncomfortable and I wanted to leave. Probably a 9 honestly. There. Are we good?”
David examined her face, wondering. A psychological effects of a sound wave producing emotions he’d expected, but not a physical sensation. Were these two things related? And Allison was so uncomfortable by just a bit of warmth? No, something didn’t add up and he wondered he might know why.
“That was great Allison, now I’m going to play it again and we-”
“What?! You can’t play it again, I thought we already had the data on it? That’s what I just told you.”
“Allison…” he reproached.
“Observations must be collected as soon as possible, any interference or room for human error could skew the observers perceived emotions. You’re right.” David smiled, it had been almost word-for-word from his methodologies paper. He never would have imagined it would be useful in a situation like this.
“You’re right. Now, we’re going to do this in stages, you let me know if it gets too much for you, okay?”
She nodded. He pressed play.
The QRS wave was the important waveform of a heart beat, the small buh-bum that was now sped up to thousands of times per second so it became a high pitched ringing. This time David did not drift away into wondered, he watched as Allison’s face became red, her knees clenched together and her breathing became heavy. After 15 seconds he stopped the noise.
Allison slumped down, looking relieved but antsy.
“How did that feel Allison?”
“Fine, warm. About an 8.”
“What kind of warmth?” David pushed a bit. Her eyes darted from his.
“…The- the same as yesterday…?”
“That’s not good enough Allison, we need more data. Accurate and reproducible.” The previous night he’d tried some tests on himself, short bursts of the sound at varying amplitudes. Nothing. He assumed that after spending months forging the building blocks for these sounds he’d become somewhat immune to whatever effect or lack thereof they had. He needed to know the actual effects before he could get excited.
He pressed play again.
Allison jerked upright, opening her mouth to say something and then, not trusting what would come out, she closed it tight. 15 seconds passed, then 30, he watched as her brow furrowed and the shifting in her seat began.
“We need to know, otherwise the whole project is a wash. Your research experience will mean nothing and all your time will have been wasted.” She was blushing again, trying not to make eye contact with him. But more than that, she seemed turned on? It seemed too good to be true as David noted her increasing ticks and twists of a strange pleasure. The woman almost seemed like she was watching a porno play out in front of her, but he couldn’t be sure. How do you feel, Allison?”
She did her best to hold back the word as it jumped from her mouth, almost a plea, “H- Hot.”
“Very good,” he tapped the spacebar, pausing the frequency after spending a few seconds drinking in Allison’s belabored expression. She stood up immediately, face a bright red and with tears welling up in her eyes.
“I didn’t mean to say that.”
“Sit down,” he said, voice firm. To his surprise, she did. They had never had the most substantial boss/employee relationship, but now she was following his orders?
“Like I said, this won’t mean anything if we can’t record the observations, Allison.” Maybe a stronger approach would help her come clean. “So quit messing around and help the experiment here. Answer questions directly and without so much god damn hesitation.”
She nodded, “Allison Smith, longer exposure to waveform 491 caused increased temperature and feelings of higher…,” she paused. “-libido.” David’s eyes widened.
“Elaborate please, then we’ll be done with this test.”
Allison sighed, leaning back as the thoughts of moments earlier rushed over her. “I felt like my body was out of my control. Like there was something I needed, and the longer the waveform went on the more I needed it. It became all I could think about before-” she stopped, remembering David had his gaze fixed on her.
“Is that all for today, sir?” Sir? He’d never been called sir before, but she was clearly going through something. And if this was how Allison would react, think of what he could do with the technology around the world…Did it work that way? So far he’d only proven it on Allison but surely he could discover another test subject, someone even less eager and maybe- he paused. Maybe someone like Christine.
David wondered about Christine’s short, full body wriggling like Allison’s had. He wondered about the way she bit her bottom lip while thinking, the way she smiled and brushed up against him on the couch. There was only one way to know for sure.
“One more test, then we’ll be good,” he stated.
“But you said-”
“I said that would be enough for that test, but there’s one more to go,” the third one pays for it all, he thoughtr
.
She opened her mouth to protest, but clamped it shut as soon as the ringing began. It was time to really put this to the test, to see how far he could push boundaries with Allison. If things didn’t go any further, then all he was looking at was a cute trick for kinky couples, not the girl of his dreams laying naked in front of him…
15 seconds, 30. A whole minute and Allison was looking dazed like the day before. After two she couldn’t stop squirming, whispering out a small moan or gasp every time her thighs rubbed together. David placed a hand on her knee, and Allison let out a small moan. She wasn’t trying to conceal them at this point.
“How do you feel, Allison.”
A short gasp, “H- horny,” was all she could manage.
“So not just hot?”
“-so, so fucking horny.”
Her eyes were glazed over as her body began to shake at his touch. At 3 minutes he watched her hands begin to inch toward the inside of her thighs and then get pulled away by some mental fortitude. They were getting closer and closer each time but David couldn’t wait.
“You can touch yourself in front of me,” he suggested.
“-want to, but no. Unprofessional.”
“No, not unprofessional. It’s for research. We need to see the effects of the waveform.”
“Need?” she pleaded, hands resting on her crotch now.
“You need it, Allison. You need to touch yourself now.”
“I need it,” she gasped, with lightning speed as her hands squirmed down her pants, fumbling to where she began making practiced, circular motions, just out of sight.
After just 5 minutes of the frequency, David watched as the girl opened her mouth, tongue splayed as if sucking an invisible cock in front of her. This was apparently all the permission she needed to go full slut mode in front of him. Her other hand reached up her shirt, finding hold and squeezing tightly beneath the sweatshirt. David’s cock throbbed as he watched his assistant playing with herself, in heat in front of him.
Allison was lost in thrusts up into her own hand, pinching at her hidden nipple and moaning, faster and faster. The thrum of the soundwave ringing all the while. Finally her body seized, jerking a few times before going limp, hands still clenched underneath her clothes. David watched Allison lose consciousness before muting the sound on his computer.
She had seemed more obedient but he was curious as to how far that would go. He needed to know before trying anything too rash. He cupped her limp head in his hand, not daring to touch the body he had seen twist so dynamically seconds ago.
He whispered into her ear, “Tomorrow, you’ll come back to continue our research, excited about what we found, and ready to learn more. You won’t remember what happened in the sound room. “Hopefully this would help dull some of the hesitation she’d felt earlier that day.
“Oh,” he stopped gathering his laptop and speaker, leaning back down. “And come in something a little more revealing. Something less professional and more appropriate for a woman your age.”
He wasn’t sure if she’d heard any of it, but it was worth a try.
* * *
That night he’d tried not to stare at Christine as they sat together on the couch watching a movie. She was in a loose t-shirt that sagged down to her cleavage, when she leaned a certain way he could almost see the dark brown nipples that lay in the shadows.
Her short hair bounced as she laughed at the movie, and in the glow of the tv he smiled at his crush. Soon, he wondered.
* * *

The next day Allison slumped in like every morning and set down her bag of books and notes from her classes.
She wasn’t wearing a sundress or maid’s outfit, but David was glad to see she had shed her usual hoodie in favor of a sweater. It must have been a few years old because the cotton clung to her thin body, outlining a nice pair of smaller breasts and stopping just short of the hem of her jeans, creating an almost crop-top look.
“You look nice,” David said, leaning back in his chair.
“Thanks,” Allison blushed as she tucked a strand of hair behind her ear absentmindedly. “I’m just sorry for what happened yesterday.”
David stopped, leaning forward again as his heart beat through his chest. “Remind me what happened yesterday?”
“Uh, I fell asleep? I guess that waveform is really doing something, maybe we can market it as a sleep aid. People would pay millions for that, you know?”
He laughed, “Oh, people will pay millions, all right.”
“Now, are we ready for more testing? I promise I’ll be a better subject this time.”
“Well, if you say so,” David said, grinning as he walked toward to sound room with Allison.
* * *
As lofi_hiphop01_wf491(FINAL).mp3 looped in the background, Christine laughed, placing a hand on David’s arm. She beamed at him, laughing at his jokes and maybe it was the glass of wine, but he was looking really cute…
After dinner, and a delicious chocolate lava cake, they were laying on the couch like typical, but now instead of being on opposite ends, she was leaning on him. She was enjoying the feel of his body and the warmth growing inside her.
“I’ve always liked you, you know?” he said.
Christine giggled, this time it was less dismissive than usual. Wasn’t she feeling a bit of attraction herself? The music was putting her in some sort of mood, although she wasn’t sure what.
“I know, it’s just…We’re friends.”
“We are friends.”
“Like really good friends!”
“I know.”
“And I appreciate everything you’ve done here today but-”
“But…?”
“I don’t feel that way about you.”
“Don’t feel what way?” David asked, turning up the stereo slightly. The ringing was more clear as it pierced through the song now. Christine didn’t seem to notice, still trying to sort out her feelings.
“Don’t feel…into you.”
“Into me, like…?”
“Like… you’re sexy alright? Just not my type.”
“You think I’m sexy?” David felt himself growing hard at her admiration. Christine could feel it too, she gently rubbed his hardening area as the music droned on in the background. It had been a while since her last breakup.
“Of course you’re sexy. You look good, you know how to talk to women, you’re funny. It’s just-”
David swooped down and kissed her. Leaning into her soft, warm lips as her hand instinctively wrapped around the imprint of his dick in the jeans. She felt vulnerable, weak as she looked up at him, her cleavage pressing into his chest, biting her lip again, unsure what to do.
“That’s how you felt about me in the past, how do you feel about me now? Think Christine, you’re into me, aren’t you?”
She was.
She needed him. Right. Now.
Her head whipped forward, reconnecting the kiss as if she were drawn in by a magnet. She bit his lip and felt her tongue surge into his mouth. This wasn’t a romantic peck, this was a carnal desire. She was looking for something to do with her mouth, something she needed. After a few more moments of searching and falling into the warmth of his mouth she pulled away. David looked at her with eyes wide, afraid that the spell might be broken until her eyes were pulled down. Her gaze steadied where her hand lay wrapped around the outline of his pulsing cock.
His pants were off quicker than he’d wondered efficient and she was down, hovering over his naked hips for a second wondering if just a handjob would do. No. She brought her face down and wrapped her dark lips around him. She descended slowly at first to get a good feel of the size and way it fit so perfectly in her mouth. Then moving faster, matching the tempo of the music. She held her hair up as she bobbed up and down his cock, moistening it with her spit as the gliding became easier, more natural.
In the glow of the fire David saw her eyes flickering as she rammed his dick into her mouth. Her tongue was magic, her hands flowing around the shaft with the motion of her lips. In, then out. She went all the way down and held it, held him like that, deep inside of her throat. She wanted to gag but wouldn’t let herself, the need was too deep.
David grunted, trying to warn her, but it was too late. He jerked forward as he exploded, cum sputtered into her mouth, down her throat. Christine paused, savoring the warmth that passed into her before pulling off of him. Panting, she licked her lips as a few strands of cum started to drip down. She smiled at him, in a daze.
“Do you want me to-” he began.
“I’m gonna go….shower,” she said, moving confusedly up the stairs and to her room. She was still smiling and blissfully unsure about why they hadn’t done something like that sooner.
David didn’t want to lose the opportunity, there was still so much research to be done on this. And on her, he hadn’t even gotten to see her body, let alone make her orgasm…unless.
“We-” he stopped. “We should do this again.”
She smiled at him, a twinkle in her eyes as she drifted away from the music.
David lay back on the couch, drained and happy for the second time that day. A lot of research to be done indeed.
