Sounds Like Lust
2002
By animus

I read a nice little piece on the uses of infrasound in crowd control situations. Ultra-low sound frequencies can have odd effects on the human body, and have been observed in naturally occurring situations, such as earthquakes and volcanic eruptions. Machines to do anything from cause an epileptic seizure to rupture someone's eardrums have been patented. If you found the right frequency, I imagine you could affect the human body in any way you wish...

This story wasn't written to be a literary masterpiece, to don't Email me saying that it's sick. It was a means to an end. I wanted to see if I could weave an MC story using infrasound as a key element. Apparently I could.

Paula's high-heels clacked on the concreted path as she headed toward the house. She'd forgotten her keys somewhere, so she had to knock and hope someone was home. Fortunately, someone was, although it wasn't who she'd hoped it would be.

"Why hey there, sis. Mum said you might be around sometime today."

Yuck. It was her stepbrother, Quentin. It made her sick when he called her 'sis', which was probably why he did it. He stepped aside to let her in, the eighteen year old girl slipping off the uncomfortable heels as she pushed past him.

Even without the heels she had a good few inches in height over her older step-sibling. It was something she used against him in their frequent clashes. "Where's Mum and John?" she snapped at him, refusing to call Quentin's father 'Dad'.

"Oh, didn't you know? They had plans to go out tonight. I don't think they'll be back 'til tomorrow afternoon."

"Shit," she muttered, heading for the fridge and grabbing a Diet Coke. "Well if I have to spend the night alone in the house with you," she waved a hand imperiously," then I'd rather spend it in my room." With that she walked off the direction of her bedroom.

"Hey, wait. There's something I want you to see first," said Quentin quickly.

"What?" she said, hands on her hips.

"New sound system. Cost me a bundle, but it's gonna' be worth every cent."

Her interest piqued, Paula put down her drink and padded back to scrutinise a large speaker, about a metre tall, with a small device looking something like a portable disc player sitting on top. The casing of the player had been removed, and button panel had been added.

"Big speaker... wow," she said, unimpressed. "Can I go now?"

"Just listen to the quality first," her brother said, pressing a button on the player.

"I don't hear anything," she said, putting her ear closer to the mammoth speaker.

"You will, don't worry." He adjusted a knob on the side of the speaker and pushed up the volume.

"I think your precious boom-box is broken," she said with a thin smile. "Take it back to whatever junkyard you pulled it from. I'm going to my room."

"Oh, I don't think you'll be doing that just yet."

Paula turned. "And just why not?"

Quentin turned and pushed another button on the player. "That's why."

Instantly the air seemed thicker, as though she were in the front row of a rock concert but had gone deaf. She still couldn't hear anything, but something was definitely making the air pulsate around her.

"What the..."

Another button was pushed, adding another sound to the air, and with that Paula's breath was knocked from her lungs. She hit the ground with a frantic moan, reaching under her short skirt with both hands and rubbing her pussy with abandon. All of a sudden her crotch was on fire! Her step brother smiled.

"How you doin' there, sis?" he asked jovially, kneeling beside her. "Feeling a tad twitchy?"

"Uhnnnnnn!" she groaned in response as she shoved her fingers into her suddenly sopping cunt. Her flimsy panties were pushed to the side in her haste as one hand filled her and the other rubbed frantically at her clit. He could see her body begin to twitch with her oncoming orgasm and stood to better appreciate the view, slipping off his shoes and undoing his belt as he watched.

"Mmmmm... nice view. You never told me you shaved your pussy. We're supposed to be family - you can tell me anything, you know."

Paula's head lashed back, her eyes squeezed shut and tears streaming down her face. A shattering orgasm drew frantic cries from her lips as she spasmed, then a long, drawn out "FUUUUUUUUUUUUUUCK!" as a final spasm was wrung from her body. She fell back and hit the floor like a limp rag, her lungs straining to recatch her breath.

"Enjoy yourself there, sis?" smiled Quentin. Paula sat up fearfully, pulling her skirt back down and trying to get to her feet. Quentin was naked, his cock standing at rigid attention. To her surprise, it was alot bigger than she'd thought it would be. Not that she'd ever wondered about how big his dick was, of course.

The worst part was, she could feel herself aching for it as her pussy began to twitch and jump unbearably again. Her eyes squeezed shut as she shuddered. "Oh, God no... ohhhhhhhh."

"Something I can help you with?" came the voice from above her. She knew that it was wrong, but she couldn't help slipping her hands back into her panties and working her already sore vagina again. Her hands shook with lust, and she couldn't get her panties off, so she settled for slipping them aside once more.

Another, more steady, pair of hands pushed hers aside and slid her panties down her thighs and off her ankles. She shuddered as the soaking cloth rubbed her pussy and thighs on the way down. God she was so horny! She didn't realise her fingers were again frantically at it until they were pushed aside once more. She moaned in frustration.

"Pleeeeease!" she begged. "Oh, God please!"

"Please what?" came the voice again. "Tell me what you want."

"Please let me."

"Please let you what?"

"Let me come. Oh, God let me come, I need it so bad, I need it, I need it, I fucking need it!" she whimpered.

The voice tut tutted as her hands were once again moved from her crotch. This time they were held above her head and she felt Quentin position himself between her legs. She knew that it was wrong, but she needed it so bad. Her clit was on fire, buzzing and twitching in time to a rhythm she couldn't hear but could feel in the air all around her.

"You want it?"

A part of Paula balked at this - their parents were married, even if she and Quentin weren't really brother and sister. No one would blame them if they did, another, more primal part of her brain whispered to her. She heard her own voice cry out for him to do it.

"You got it, sis," he whispered, his hot breath in her ear making her squirm.

She humped her hips up at him, demanding the cock she so badly needed. He paused a moment, then pushed the head inside.

And Paula's world exploded.

"Oh GOD! FUCK YES! FUCK ME FUCK ME OH GOD FUCK YEEAAAAAAAAAAH!" she screamed as he slowly pushed his entire length into her impossibly tight channel. Despite being soaked through, her pussy was unbelieveably tight, brutally squeezing and clutching at him in unrelenting spasms. Her hips bucked up at him as he sank down inside her and started fucking her for all that he was worth.

"Oh, yeah! Fuck yeah!

"You like that, you prissy little bitch, huh? Not too good to talk to me now, are you?"

"Yeah, oh yeah! Don't stop, just don't stop. Neeeeed it so baddd..." her voice trailed off into a ragged moan of animal lust. With her eyes still closed she couldn't see him, but she could feel him taking advantage in every way, his hands mauling her tits and twisting her nipples. She pushed her breast into his hand harder, hoping he'd squeeze it more brutally. Paula was shocked with her behaviour, but didn't care, she just couldn't care when it felt so goooood.

Abruptly, Quentin pulled his dick out. The overheated girl cried out in surprise and disappointment, her legs wrapping around his waist trying to pull him back in again. Quentin was having none of it.

"No."

"What do you mean 'no'? I need it! Put it back in, give it to me!"

"Why should I?"

"Because I need it. I want you to fuck me. I gotta' have your big, hard cock inside me," she whispered, looking like she might start crying.

"Beg."

Without hesitation, Paula started pleading as though it were her very life she was begging for. "Oh, please fuck me, Quentin. I need your cock inside me, stretching me, making me come. Come on, please give your little sister what she needs? Paula needs you to fuck her so bad," she whimpered, desperate with need. If he wanted a performance he'd get a performance. She'd say whatever he needed, just so long as he put it back inside her. Meanwhile, her legs had pulled him in against her, but his dick was laying flat against her body. The best she could do was rub her pussy against the hard base of his prick and try to get herself off that way.

"You want it?" demanded Quentin, stroking the tip of his cock around and around her slick slit.

"God yes. Fuck yes! Please give it to me! I'll do anything you want!"

That was all Quentin needed to hear. Teasing her a little more by stroking her clit, he plunged back in, loving the feel as he sank deep inside and the sound of her wailing as she clutched at his back, digging her fingers into his flesh. She bit into his shoulder hard as her legs crushed his sides.

"Yes! Oh God yes! Yeah, oh fuck yeah. Fuck me baby. Bruise me with your big cock, honey, yeah!" she wailed nonsense as he pummelled her brutally, not giving her a chance to do anything but come. He could feel that familiar tightening and knew that his orgasm was coming fast.

"Gonna' come, bitch? Huh? You gonna' come now, you filthy little whore?"

Paula didn't answer. All she could do was shake and wail as the orgasm shattered her senses and made her scream for more. She felt Quentin still moving fast, and knew that he'd be coming soon, too. She was on the pill. She didn't care.

Gasping out a hoarse warning, Quentin came and came and came, his load swamping her insides and making her seem even slicker. He finished quickly, but kept pummelling at the girl beneath him. He couldn't come again so fast, but he knew that Paula could. Soon her cries hit the air again as she scrabbled at his back with her fingernails, her pussy clenching at him exquisitely. His muscles aching, Quentin slowed down, and finally stopped.

Quentin gasped for breath as he lay on top of her, amazed that she was still humping her pussy up at him. He let himself slip out of her warm confines and walked over to the player, switching off each of the source tones in sequence. Paula's body went limp, but her hand still snaked down to her pussy. Must be some residual effects, Quentin figured. He decided to trash the idea of using infra-sound for his senior thesis. Instead he'd keep his findings for his own, private use. Maybe he'd turn in a potato in a jar instead. Who knew. The air felt empty without the modulated sound vibrating away. He wondered if there was a way to make it less noticeable in future.

He picked up the video camera from its hiding place behind a cardboard screen next to the television. He'd carefully placed it so that the camera would get a perfect angle of Paula when the device took effect. Slipping open the viewing screen, he angled the camera at her as he took a seat on the couch, still filming. Her fingers ran lazy circles around her clit as her other hand slipped two fingers in and out of her pussy. Unexpectedly, she brought her fingers up to her mouth and slowly sucked them clean of the mingled come and girl juice. Quentin laughed.

Maybe he'd use the sound generator again, perhaps concealing a few smaller speakers in her bedroom whenever she stayed over. He was sure that he could make it smaller, now that he'd perfected the design. The hard part had been making the response specific to the female body. Regardless, with the video tape he had her at a definite disadvantage, should she ever decide to try something in the future.

"Queeeentiiiin," Paula called in a little girl voice. He zoomed the lens in on her face as she sucked her fingers like a child, her face looking innocent with her big 'come fuck me' eyes. "You wanna' come give me some more? Paula really needs your big cock so baddd. Pleeeeeeease?"

Not that he thought she would.

Quentin smiled as he zoomed out again and set the camera down on the coffee table, making sure the lens was fixed firmly on the scene at hand. He'd worry about the details later.
