From louvre@dido.fa.indiana.eduFri Nov 24 15:41:56 1995 Date: Fri, 24 Nov 1995 16:20:56 -0500 From: The Louvre To: orelious@ICSI.Net Subject: Re: request (auto response) To: louvre@dido.fa.indiana.edu Subject: SUBMIT the-invention-(corrected) INVENTION Sandy Wilson looked at the rat in frustration. The aluminum foil electrode he had glued to Ms. Piggy's head had come loose again, and she had rubbed the spot where it had been attached until the skin had broken, making it useless for his purposes. He'd have to find another place to attach an electrode, and that meant another hour of carefully shaving the rat's tiny head. Still, he hadn't got a good EEG tracing from the spot on top, so he probably was better searching for another, maybe farther back on the cortex.. He sighed and lifted the plump warm animal, cupping her in his hand. Ms. Piggy didn't seem to mind the shaving, because he worked carefully and fed her slivers of moist cat treats while he worked. Eating was her favorite pastime, which was how she earned her name. That and the fact that she chased Mr. Ed, the male mouse, around the cage, nipping at him until he huddled in a corner. Unless she was in heat. Then she let him mount her, but immediately afterwards began biting him again. Mr. Ed seemed resigned to this peculiar form of courtship, taking what he could get when he could get it. But otherwise he avoided the female rat completely. Sandy had carefully charted her menstrual cycles and knew she still days away from any friendly interest in Mr. Ed. He knew better than to toy with her during her single-minded pursuit of the male animal. She should be safe to handle today. As always, he talked to her while working the fingernail clippers, then shaved the stubble carefully with a scalpel held in a metal jig.. Finally a round quarter inch spot was clean. He took an alcohol swab and touched it to the area. She flinched at the cool swab, but didn't squeal. He lifted a pre-pasted dot of foil and pressed it onto her scalp, then deftly attached the electrode, sliding it into the small copper tube he'd soldered onto the foil.. He the rat her into the recording box, small enough so she couldn't turn around or reach the electrode. Ms. Piggy smelled the lettuce cuttings in the box and immediately began stuffing them into her mouth, eyeing him while she chewed the leaves. Sandy turned on the recording equipment, watching in satisfaction as the scope showed brain wave tracings. He had apparently stumbled on a good spot, for he was getting clean sharp waves of brain activity. This was his junior science fair project, building on his sophomore project, which was chemical analysis of hormones from rat urine. He was charting the changes in brain waves against the rat's chemical changes, looking for correlations. His previous female subject, Stinky, was Miss Piggy's mother. She had gotten him all the way to the State Science Fair, where he won Honorable Mention. This year, he wanted to take First Place, and was determined that the methods he used were meticulously scientific. He noted with pleasure that Miss Piggy was pissing in the box, a conditioned response he'd trained into her since her infancy. The yellow fluid collected in a test tube fitted to the hole in the bottom of the box. He'd have to start all over again, measuring the hormone level in the rat's urine and comparing it with the tracings from the new location on her head. He'd long gotten over his distaste for the sharp smell of the rat urine, but still wore latex gloves whenever he worked with it, hating to get the yellow fluid on his hands. The electrode was his own device. He'd built it using a tiny Hall effect junction removed from an airplane navigation system, lifting it out of its plastic case with tweezers and gluing it to a FET which he'd pried from its own case, wrapping the pair carefully with speaker wire to form a tiny tuned inductor, highly sensitive to the smallest changes in an electric fields when excited by an oscillator, and he'd build a bank of active filters, run into an analog neural network constructed from capacitive diode junctions to remove unwanted electrical signals. He checked that the tracing he wanted was complete enough to analyze. Ms. Piggy was still toying with the last of the lettuce. He didn't want to disturb her, so he fiddled with the tuning of the oscillator, varying the frequency while watching the amplitude of the brain waves reflected on the oscilloscope. He was getting nothing but noise now, and was trying to decide how to better shield the leads to simplify the filtering. He noticed that every time he moved his hands the tracing would change. The device was behaving like an ultra-sensitive proximity detector, not like a brain-wave monitor. He increased the amount of 60 cycle current into the neural net inhibitors, hoping to suppress the effect. Suddenly Ms. Piggy's body quivered and she let out a tiny squeal. He turned off the power immediately, afraid he'd somehow given her a shock, then realized that the ultra-thin speaker coil wire he was using for the electrodes could hardly carry enough current to hurt her without burning through. He turned the oscillator back on, trying to remember the settings he'd run through, and watched the animal carefully. Again she quivered and squealed, then unconcernedly returned to nibbling at the lettuce. He checked the pen recorder tracings, and noticed two sharp sets of spikes. Sandy thought carefully. He wondered if he had somehow induced a brain wave in the small white furry animal. This was unexpected, at the least. Perhaps, he thought, the tracing reflected some design flaw in his equipment. Maybe he'd started an oscillation that quickly built up a large current at some fundamental frequency he hadn't filtered. He carefully removed the electrode from the piece of foil, then tried the oscillator sequence again. No spikes appeared. Maybe Ms. Piggy's body was necessary for the proper currents, like a load on the coil. He picked up another piece of foil and stuck it on the naked skin of her tail, using the same glue. Again he ran the oscillator cycle. Again he got the spikes, and a shiver from that rat. But both were much smaller. He returned the device to the foil on her head. This time he programmed the sequence of oscillator frequencies into his computer, having wired it long ago to excite the coil with variable waveforms to get the greatest sensitivity from his sensor. Ms. Piggy didn't seem to mind, her body only shaking slightly at his touch. He tried again, and again he got the strange spikes and the same quiver and squeal. He pasted another electrode on the scar tissue, hoping it wouldn't hurt her when he peeled it off later, and tried again. The same squeal, and the same strange tracings. He thought a while, realizing that his new amplifier was obviously involved in this effect. He looked at the tracings carefully, noticing that the waves showed some sort of feedback effect, from the rat's faint brain waves through the excited coil and magnetic junction, then amplified back through the device. Sandy knew the electronic characteristics of his device quite well. He returned the mouse to her cage and lifted another sensing device out of its box, quickly wrapping a larger coil around a pencil, cutting the fine speaker wire on the device and soldering the new, larger coil into place. He cussed as the fine wires curled away from the soldering iron, the head too intense for the thread of copper. He wrapped another coil, then soldered it more carefully, this time succeeding. He lowered it into Miss Piggy's cage, holding it a few inches over her head. The rat didn't seem concerned. She was used to strange devices by now. He tried to reach the computer keyboard but the rat wandered out from under the coil before he could begin the sweep. He typed the required command sequence, programming it to repeat every second, then held the coil over her head. Again he saw the familiar shivers. She walked directly to Mr. Ed and Sandy knew she was going to begin her familiar ritual of torturing the male animal. Sighing, he reached to take her out of the cage. He wasn't finished with her yet. To his amazement, however, as soon as she reached the male animal she presented herself for coitus, front paws spread and her rump up.. Mr. Ed took immediate advantage of the opportunity, sniffing her in confusion, then mounting her from behind, pushing his cock into her and pumping hard.. Sandy marked the urine sample, wondering if he'd missed something in her estrus cycle. He watched the rats go at it for a few seconds, then lifted Smurfette from the cage, thinking he would try another animal to get the strange feedback effect. He put the young female rat in the lettuce box and lowered the coil. Smurfette was Miss Piggy's daughter. He started the equipment and was pleasantly surprised to find that this animal responded the same as her mother, without the squeal, her sexual arousal obvious as her little body quivered.. He reached toward the box, and Smurfette bit him. This was unexpected, too, but the bite didn't hurt. Sandy dabbed his finger with antiseptic from the bottle he kept near the rats' cages, thought about writing the results of this experiment in his lab notebook, and decided he'd wait to see if the effect could be repeated. He lifted the coil, but the fine wires broke. He tried several times to solder a new coil, but couldn't get it right. Frustrated, he switched off the equipment and went upstairs.. The next day Sandy built several new electrodes.. This time he didn't have any problem soldering the thin wires. Somehow his hands seemed steadier. He found he could replicate the effect at will, holding the thin coil over the rats' heads with tweezers. The coil seemed not to affect male rats much, but it had a decided and immediate effect on female rats, causing an immediate sexual arousal. He was playing with the coil, trying it on all his rats at once, two male-female pairs and his two extra females. The two females, isolated from any males, were the most interesting. One of the females would assume the male position, trying to mount the other while both of them squealed excitedly. The next several days he repeated the experiment, trying various combinations of oscillators and filters, and tuning the circuits to maximize the effect. He found that by using more loops on the coil he could make the rats fuck from several feet away, by having two separate coils, one which seemed to act as a receiver and one which acted as a transmitter. The rats didn't even have to be between them, as long as they were close. He was spending more and more time in the basement, unable to pull himself away from the experiments. About a week later, he was still working on his project. He had built a bigger capacitive diode array, hoping to expand the work to other appetites than sex, but wasn't getting any results, except faster sexual reactions. He turned sharply as he heard his older sister Samantha coming down the basement stairs. He realized that he was embarrassed to be caught watching the three pairs of mice fucking madly away in the glass cage. His sister was a year older than he, and about the most prudish person he knew. He thought that if she weren't his sister, it would be a terrible waste. She was a year older than him, just turned seventeen and one of the prettiest girl in school. She had a pretty face, even beautiful in an all American way, and a well developed body with full firm breasts and a narrow waist leading to nicely shaped hips and long shapely legs. He knew that some of the boys thought she was an awful tease, but that wasn't it. It was just that she didn't seem interested in sex, or even to really understand that sex was a part of every teenage boy's interest in girls. Sammy complained to him sometimes about boys, but Sandy always avoided the conversations, embarrassed.. Samantha, whom everyone called Sammy, wasn't half the student he was, but her athletic ability had won her a gymnastic scholarship to a good college. She was serious about schoolwork, but never really got into it. She didn't share his interest in science, preferring to study sports, and was looking forward to the end of her senior year. She'd been on the Tri-County gymnastic team, and had almost made the State finals, losing out last year to a potential Olympic contender. She'd also been a cheerleader for three years, and was captain of the team. Most of the really pretty girls that Sandy had dated had met him through her. He was regarded as nice by her friends, he supposed, but sort of dull. "What's so interesting?" she asked, walking over. She still had on her cheerleading outfit, carrying the bag with her sweater and pom poms. "These rats," Sandy replied, covering the cage with a cloth. "They're not doing what I expected." "Ugh! They're so gross anyway. You can keep that cover on the cage, thank you very much. What are they doing that's not expected?" "Uh, they're not eating the cat food pellets," Sandy lied. "They've always liked them before." "Maybe you should try rat food like everybody else," she said. Sandy couldn't tell whether she was serious or making a joke. "Maybe," Sandy said. "Look at the new device I'm building." Sammy leaned over and looked at the larger coil of wire. "What's it do?" "It oscillates," he explained. "In a funny way." "OK, but what does it DO?" Sandy turned on the equipment as his sister leaned over the coil, looking at it closely. "It's bigger than the little things you've been building before." She reached out to it up as he started the playback device. "Don't touch it," he warned. "It's set to oscillate by itself." "Is it dangerous?" she asked, pulling her finger quickly away. "No, no. It just won't work the same if you're touching it. It picks up body currents." The oscilloscope tracing jumped as Sammy quickly inhaled, shivering. "Oh!" she exclaimed, backing away. "Did it just give me a shock? I just got a really funny tingle. And I, well, I don't know. I think it gave me a shock!" "No, it can't do that. I think it just picked up your shiver. If anything moves fast, then the electric field changes, and it's really sensitive to that. It's cold down here, and that's probably what caused the shiver." "Probably," she said, looking a little doubtful. "Are you sure that thing's safe?" "Oh yeah," he said. "It carries current only in the milliamp range. Watch, it's about to cycle again." "Look, I'll turn the current down by half," he said as Sammy backed away, looking concerned. "But there's no way it could have shocked you. You get more current walking past a florescent bulb!" Sammy came closer and watched as the device appeared to do nothing. She didn't seem to notice that her fingers flexed just when the device oscillated, the tracings on the oscilloscope converging into a complex pattern he didn't recognize. But Sandy noticed, wondering why it didn't have a similar effect on him. He watched as the neural net tried to stabilize the signals, which finally converged into several complex overlapping wave forms. "OK, so it doesn't do anything. Then what's it good for?" "It's a sensitive detection device. A measurer," Sandy said. "That's all. It measures tiny electric currents, using what's called phase matching to make itself even more sensitive. Sort of figures out what you want to measure, then does it for you. It really means I don't have to paste these electrodes on the rats." "Lucky for the rats," Sammy laughed. The scope tracing flickered again, showing that the neural network circuits were trying to stabilize a new pattern. Then they settled into the old pattern as Samantha's fingers flexed in time with the cycles. Again she didn't notice. She ran her hands over her blouse, smoothing her uniform. To Sandy it looked like she was squeezing her breasts. "I gotta go upstairs now." "What did you want to tell me?" Sandy asked her. "It can wait," she said, suddenly seeming upset. "I really gotta go upstairs, Sandy. I mean, I'll talk to you later, okay? It's too cold down here! I keep getting these shivers." Sammy turned suddenly and ran up the stairs. Sandy watched her, trying to figure out if she still thought the device was dangerous or what, then turned the current up, to the maximum range he thought the thin wires of the coil could handle. He pulsed it while his eyes were closed, trying to feel something. He thought that he felt the hair on the back of his neck rise a little. He tried again, feeling the same thing, then switched it off. He lifted the cover of the rat cage. One of the pairs of rats was still fucking furiously. One male rat was panting exhausted while the left out female was licking herself between her hind legs, her paws trembling violently, and the two female rats were pushing themselves against the side of their cage, trying to get to the male rats.. Sandy made sure everything was turned off, then left the rats, knowing they'd be okay. They'd all been through this before, and the only noticeable effect was a subsequent increase in their sleeping cycles, although the hormone levels of the female rats would go way out of wack for a while. He climbed the stairs, wanting to talk to his sister. He knew he couldn't tell her about the rats. She'd be furious that he'd exposed her to the device. But she'd wanted to tell him something, he knew, before she left so suddenly. He got to the first floor, but she wasn't in the den, or the kitchen either. He went upstairs to where the bedrooms. Maybe something was wrong with her. When he got to her bedroom, the door was closed. He raised his hand to knock, then paused, listening. He could hear strange noises coming from her room. "Unnnnh! Unnh!" he heard. "Ahhhh.... oh!" He waited a second, then heard another noise, like a cough, but longer. "Oooh! Aaaah! Unnnnh!!" He quietly turned the knob on the door, opening it a fraction of an inch and peeked through. His older sister was lying on her bed, still in her yellow and blue cheerleader's uniform. But the short, satin-lined skirt was yanked up to her waist and her eyes were closed. Her knees were raised. Both her hands were stuffed into the tight yellow pants of her outfit. He could see her fingers rubbing right over her crotch. He couldn't believe that his sister was frigging herself, but the evidence was unmistakable! He watched for a moment longer as she pulled one hand out from under her pants and moved it to her chest. She began kneading her breasts through the top of the uniform while her fingers worked in her pants. Her body began to shake and she pointed her toes, rubbing herself faster and faster. Then, making one final groan, she rolled over on her stomach, her body writhing and her short skirt flapping up and down over her rear. He saw her face beginning to turn towards him and quickly closed the door, jumping at the slight click of the catch. But the noises continued unabated. His sister hadn't noticed. His head whirled as he walked down the stairs to the living room. His sister was upstairs frigging herself, right after being exposed to the device. Just like the rats! He wondered what her boyfriends would say if they could see little Miss Perfect working her fingers into her panties, obviously rubbing her pussy! Sandy had tried to get peeks at his sister's body before, but had never seen much, just an occasional view of tit inside her bathrobe after she took a shower. He knew she had a reputation as an ice maiden. He'd heard some of the kids at school joke about it. She'd never do anything except kiss, and then not even with her tongue. But the picture of her working at her pussy, at her snatch, at her sexy cunt, burned in his mind. His sister had sexual desires, just like he did, and she was upstairs fingering herself on her bed, just like he'd wanked his dick beneath his covers at night. He knew what his fantasies were--he dreamed of screwing the ever girl at school, pretty, ugly, fat thin, it didn't matter. His horny cock wanted all of them and at one time or another he'd pictured himself fucking them. He wondered what she was thinking as she masturbated, which of the boys at school she had pictured in her mind. He shook his head. He guessed that the rapid onset of his sister's sexual desires hadn't been entirely natural. It just wasn't like her. Maybe, he fantasized, he'd invented a sex machine! And it didn't work only on cats and rats, but on people, too. If it would work on Jennifer... Jennifer was his main girlfriend, or had been. She was average looking but smart, one of the few girls who seemed to understand Sandy's serious nature and his long-winded explanations of the physics of almost everything. And, as far as he knew, she was a virgin. She seemed intent on staying that way, too. Their last date she'd let him kiss her, and even touch her breasts through her blouse. He remembered kneading the soft flesh with his fingers. But he had tried to undo her buttons but suddenly she got highly offended. She told him she wouldn't go out with him if he insisted on trying to take her clothes off. He'd told her that he couldn't stop himself, that she drove him crazy. They'd had had a full blown argument, although he didn't really understand why. Jennifer had walked away, leaving him with a hard-on that didn't go away until he got home, disappearing into his room for a self-inflicted hand job. The hell with Jennifer, he thought, still half fantasizing. Now he had his Device. He'd begin thinking of it with a capital letter--the Device. Maybe it would work on Tammy Brown, the prettiest girl in his school. Or on Miss Elgin, the sexy-looking English teacher with the most bodascious bod he'd ever seen. Or on Mrs. French, the big-titted divorcee, the woman he gardened for to get the money to buy his equipment. But first he'd have to find an excuse to get them alone in his basement. Sandy laughed to himself. It was like catching birds by putting salt on their tails. Nice if you could get that close. Then he realized the solution. He'd have to make a portable version of the Device! His fantasies were interrupted as he heard water running upstairs. In a minute his sister came down. She'd changed into tight jeans and a sweater. He looked at her with new interest, seeing the slight mound at the vee of her crotch and noticing how her breasts made nicely rounded mounds beneath the woolly material. "Hey! Are you okay?" he asked her, thinking of the scene he'd watched just a few minutes ago. "Oh sure," she said. "Like you said, I just got a chill. So I put this sweater on. How can you work down there when it's so cold?" "I'm just used to it, I guess. You sure you're all right?" "I'm fine," she said, looking a little annoyed. Then she smiled. "Just fine." "What were you going to tell me?" "Oh, let me think." There was a pause. "Only that I saw Jennifer, and asked if you and she were going to go to the football game. She told me you'd broken up with her, so she didn't think so. Is that right?" "I guess. You might say we had an argument." "Oh, I'm sorry. About what? I really liked her!" "I don't really know. It was sort of stupid. But maybe I'll call her to apologize. I just don't know what we were arguing about, really. We just got angry. I was thinking of apologizing to her anyway. I believe we can work out whatever the problem was." "I guess that happens. Things just blow up. For us, I mean kids our age. Like sometimes we get these emotions that just sort of take over, you know." Sammy looked a little confused, but continued. "It probably has to do with hormones, or something, just running wild. I mean like sudden changes of mood. You know about that stuff, don't you? Hormones?" "Well, I'm not a doctor or anything, but I know something about hormones, I guess, from the chilly basement." "Like, is it normal sometimes to just get overwhelmed by anger or other stuff? I mean to just have it sweep over you? Feelings about someone? Is that normal?" Sammy looked embarrassed. "I think so, if I know what you mean. It happens to everybody." "Umm . . . Okay. Anyway, if you and Jennifer get back together, maybe we can drive to the game together. With Tommy and me, I mean." Tommy was his sister's current flame. He was on the football team, and he had his own car. Sammy was a cheerleader, and went to the games with him. But she'd never invited her brother along before. She knew that football wasn't high on his list of interests. Now she stood in the living room looking at her brother, waiting for a response. Sandy thought a minute, then agreed. "I just thought we should do more stuff together. You and me, I mean. Like double dating." Sammy looked embarrassed, then shrugged and walked into the kitchen. He could hear her opening the refrigerator, and had a wicked picture of his sister as one of his experimental rats, biting into a head of lettuce. His thoughts returned to his Device, and he began to devise ways to make it portable, small enough that he could carry it around without anyone noticing. Let's see, he thought. If I use five or six nine volt batteries with a step-down circuit and low power FET amplifiers, I could probably fit it into a knapsack and still have enough power for four or five hours at the minimum. I'd have to get a portable computer, maybe a notebook type for a control device. I can't see myself turning knobs on the middle of a date. 'What's that? Oh, just a new radio. Take your panties off and watch the movie.' Never work. Need a computer. Damn, I don't have enough money for that. Maybe if I mounted a microprocessor inside the power supply? He began designing new circuitry in his head, with a smaller power supply and a bigger coil. He could run the control computer--now there's a funny term, he thought--off the same power unless there was some other feedback problem. Maybe it should have a rechargeable supply for the amplifiers. He wondered if his father would miss the batteries from his rechargeable drill. He decided he could rewire the drill just a little he could probably arrange to get the batteries. So many things to do. So little time. . . By late Friday night Sandy had completed his smaller model. His father had used the drill, as expected, to complete the bookcase he'd been building, and the flash and smoke from the slightly modified motor were impressive. Sandy asked if he could have it for his Science Project, and his Dad had given him the still smoking tool, telling him to be careful with it. He lifted a microprocessor from his school science room, realizing he was stealing, but not really caring about such fine points of morality. Science was at stake here. He carefully wrapped a new, larger coil, with the same thin speaker wire, unwilling to make too many changes for fear the Device would have some awful side effects, soldering it with great care onto the last of his junctions. Sandy was afraid to test the new Device, thinking that perhaps some flaw in construction would cause it to scramble his own brain waves. He went to his closet and got a football helmet, sticking aluminum foil all over the outside for shielding. Then he unwrapped screening left over from the breezeway, piling it over his rat cage with the Device inside. He rigged a remote control and went into the next room. He couldn't think of any way to shield it better. He held his breath and turned the Device on. He waited, counting for four or five pulses. That would have been enough for the other Device, he knew. He switched the Device off, pulling off the shiny helmet and reentered the room. The coil was still mounted on the outside of the rat cage, and was pleased to see that the female mice were healthy, approaching the males. Within minutes the mice were happily copulating, fucking their brains out, in fact. He left the helmet off and gave them another jolt. The females all exhibited that characteristic quiver, but his brain stayed intact. In fact he felt nothing at all. Using the old Device, Sandy had discovered that pulsing the oscillator in half-second bursts worked better than a steady current, and had fitted that improvement into his new model, its timing controlled by the stolen microprocessor. The new Device fit easily into a small padded sack that Sandy had found in the garage and fit easily into his knapsack with space left over for schoolbooks. The wonders of miniaturization, he thought. Now he needed a date. He had decided to ask some girl to walk by the lake with him. He could pack a lunch in the knapsack. There was plenty of room. He knew just the spot, but hadn't picked the girl. Sandy had trouble sleeping. He kept fantasying about using the Device on every girl in school, trying to decide who his first subject would be. On Saturday morning, he sat at his desk and made a list of all the girls he thought he'd like to fuck, ranking each one for looks, personality, and general sex appeal. He decided that he also had to rate them on the chance that they would agree to go to the lake with him, so he added another column. He considered turning the Device on in the middle of a class, say Civics, but realized that the chaos if it worked as expected would not be worth the risk. Sandy went to the basement, suddenly afraid that one of his parents would look inside the knapsack, and carried the Device upstairs to his bedroom. His parents were in the kitchen, eating breakfast. They were off to an Elk's picnic, his father said, and should be back by suppertime. His mother gave him a quick hug as she picked up her purse. "What's in the bag?" she asked. His heart jumped. He hadn't finished sewing up the cushion and he knew if anyone looked at his Device they were bound to ask him why wires were sticking out everywhere. "Just some schoolwork," he replied. "And stuff for the Science Fair." "You've been spending an awful lot of time working on that," his father said. "Just make sure your studies don't suffer. And I hope the reward is worth the effort." "Oh, I expect it will be," he grinned, watching as they left for the car. He proceeded upstairs to work on his list. As he went to his room he noticed Sammy in her room with the door open, reading a magazine, stretched out on the bed in her bathrobe. Sandy knew she had cheerleading practice on Saturdays. "What're you doing home?" he asked. "Practice was cancelled. Haven't you noticed it's pouring rain outside? And there's basketball practice in the gym. They postponed it, so I've got plenty of time." Sammy was lying in about the same position she'd been in when he peeked at her before. Of course, she had her robe on now, and her hands weren't buried in her pants, but seeing her slim body and exposed long legs, Sandy had a flashback to his earlier view. Knowing it was wicked, he mentally added his older sister to his list. He quickly crossed her off again. She was his own sister! But he was really curious to know if the Device would work. And if it worked on Sammy, he figured, it'd work on just about anybody. He decided there was no time like the present to test his new model on a human subject. Besides, he had a test line with her--the old Device had seemed to have quite an effect. But how to get away with it? He thought a long time, mentally trying one strategy then another. A distraction, he thought. What to use for a distraction? He had an inspiration and went back to the basement where he picked up a test tube. He put a few drops of rat urine into it, then went to his mother's room and added a drop of perfume from one bottle and a drop from another. He sniffed it, and it smelled strangely sweet and musky, almost familiar. He went to the den and added a few drops of whisky and some white creme de menthe, smelling it and mixing in different liquors until he was satisfied that the result didn't smell like anything he recognized. Then he returned upstairs to his bedroom and wired the ON/OFF switch for the Device into the straps of his knapsack. He put his hand next to the coil and switched it on. He felt the familiar tingle at the base of his neck. Sandy waited. One pulse. Two pulses. Three pulses. Right on time. Then he closed the knapsack and walked into his sister's room. He stood by the door thinking, making sure he had his scenario straight. "Can I talk to you a minute?" he asked. "Sure," she said, demurely gathering her long legs under herself as she sat up on the bed. Sandy felt his heart pound as he thought about what he was about to try. "What's up?" "I wanted to talk to you about hormones. And perfume." "Okay," she said, putting down the magazine. "What's up?" "I blended this stuff up at school. I think it smells something like human pheremones, and wanted your opinion. Do you think I could market it as a perfume?" He reached into the knapsack and pulled out the test tube, loosening the cork and handed the tube to her. He dropped the knapsack on the floor next to the brass headboard of her bed. He suddenly wondered whether the conductive metal would shield the subject. Maybe it would act as an antenna? She took it, removing the top. She sniffed, wrinkling her nose. "Phew! It smells awful! I don't think anyone I know would wear it! You may know a lot about phere-whatevers but you sure don't have a nose for perfume!" "Maybe it's just too concentrated?" he said in a hopeful voice, secretly turning on his transmitter just as the vial passed under his sister's nose again. "Try it again, this time not so close." His sister passed the vial under her nose one more time, then gave it back to him. He had timed it perfectly so that the shiver that seemed to accompany the transmitter was concealed by her reaction to the smell. "Ugh. Still awful." She exhaled and pressed her fingers to her nose, as if brushing away an insect. "Ugh again, I can still smell it!" He watched as another small shiver passed over her body. One second later there was another. The Device was working! At least he thought it was. He switched it off, hoping that the chain reaction he'd noticed in the rats would take its course. Sammy shook her head. "I think it made me a little dizzy. What's in it, anyway?" "Just some of the chemicals I've been using. I thought it smelled really nice. Sort of sexy." He took a sniff himself. Silently, he agreed with her. The stuff smelled really bad. "I think you need a nose examination," she said, breathing deeply. She thought a second, then shook her head as if clearing her thoughts. Right on time, he thought to himself. Then she looked at him strangely. "Or maybe you don't know what sexy smells like." "What does 'sexy' smell like?" he asked innocently. She looked at him again, then leaned back on the bed. Another shiver. He put the stopper back on the vial and returned it to the knapsack, turning off the Device. "Ugh! Nothing like that! That stuff's awful. Sexy is like smooth and clean. Sort of like a guy's body after he's taken a shower. Like when you kiss someone and smell his neck while he touches your throat with his lips. That makes me all shivery, you know? And makes my, uh, my breasts sort of tingle, like they are now. Sort of tingly and smooth and soft . . ." Her voice trailed off and her hand reached toward her chest. Then she pulled it away quickly, realizing her brother was watching. "Ummm . . . you know what I mean?" "Not really," Sandy said, moving further from the bed. It's working, he thought to himself. The damn thing really works! "What kind of tingle?" "I don't think we should talk about this," she replied, her words coming thickly. Her eyes had a glassy look. "I think maybe I should be doing homework or something, and maybe you could leave me alone for a while. Okay?" "No, no, Sammy. I really want you to tell me. What kind of tingle?" He wanted to be sure the Device worked. He figured he'd watch her reaction a little longer, just to be sure, then listen at the door like before. Maybe he'd even leave it open a bit, just to see what was happening. His sister looked at him sharply, then he saw her expression soften. She gave him what could only be called a sexy, come-hither smile. "Starting here," she said, brushing her soft hair away from her neck. She traced her finger from her neck down to her shoulder. "And here." Her hands lightly touched her breast through the terrycloth robe. Sandy watched as the flesh jiggled slightly. He felt a stirring in his prick as his sister stretched out her legs. "And little shivers slowly moving down your body to here," she continued, her voice low pitched and her hand brushing down past her stomach, pressing her robe into her crotch. "And then back up to here," as her hands returned to her breasts. Sandy watched as his sister's hand slipped inside the terry robe, opening it partway. He could see right inside the robe even though she was almost straining to hold back her hands. She licked her lips and let the robe fall half open. His prick rose in jerks as he looked for the first time at the soft mounds of female breasts. Jesus, even her nipples were visible! He saw she was wearing a thin lacy bra and as he watched her hand passed it, over the erect nipple visible through the white cloth. He felt another tingle at the back of his neck and Sammy appeared to forget he was there. She opened the top more. Now he could see both tits. He noticed with more than scientific detachment that both her nipples were fully erect. This was even better than he'd expected, for a first try anyway. His sister looked up at him. "Look, Sandy, I've got things to do. You better go now." Sandy remained where he was, thinking he'd watch a bit more. As a scientific study of his Device, of course. But his hand brushed over his jeans, pushing his stiff prick down a little. He pulsed the Device again. "What kind of things?" "Oh, Sandy! What's happening to me?" "I don't know," he replied. "What do you mean?" "Do you really want me to show you?" she asked, her voice husky and almost a whisper. She was looking up at him out of the corner of her eye, her hand toying with the edge of her robe, easing it up her legs. "Sure," he said. Sandy watched amazed as his sister's fingers slowly undid the knot at her waist and she let the robe fall completely open, looking right at him. God! Was she built! Her breasts were really well developed, standing out nicely from her body. His eyes roamed down her body, past her flat stomach and to her pink bikini panties. Her legs were slightly parted and he could make out the furrow of her pussy under the material. A tangle of hair was barely visible escaping through the silky material covering her crotch. Sammy squeezed her legs together and slid her finger beneath the brassiere, lightly stroking her nipple, lying back with her fingers softly stroking herself as she reached her other hand down towards her panties. His excitement rising, he watched her fingers slip beneath the elastic waistband. She raised her knee slightly, then brought her hand back up to her breast, pushing it upward slightly. Sandy watched her knead the soft tit flesh as a pink blush spread down her chest. He didn't know if it was excitement or embarrassment, but she closed her eyes with a sigh as if giving in to the strange feelings sweeping through her. One of his sister's hands moved right inside the cup of her bra, and the other one wandered back down her stomach, tracing a light line over her navel, inching downward as she tried again to resist the overpowering sexual urges that flooded her brain. But her hand slid lower and lower, beyond her ability to control it, until her fingers were beneath the elastic waist of the panties, then all the way to her crotch, between her legs. She gave him a long soulful look and closed her eyes. This time, though, her fingers began pressing together the two sides of her pussy, squeezing her sex tightly together and then releasing it. Again and again she did this. She was actually letting him watch her masturbate! Sandy watched his sister writhe on the bed, her eyes closed, then he reached toward her bra. He knew she could feel his fingers as he touched the clasp and with fumbling fingers worked it open. The cups fell off her chest, exposing her mounds to his hands. When he let his fingers graze an erect nipple, Sammy's eyes flew open and she started to protest, moaning as she struggled to get the words out. She seemed to change her mind and began brushing her erect pink nipples with her own fingers, sighing with pleasure as he watched. She took one stiff nipple between her finger and thumb and squeezed it, her other hand rubbing up and down between her legs. "Oh yes!" she sighed as she felt the cool air on her naked tit flesh. "That's right!" He peeled the robe all the way open, her flat stomach and full hips now showing. Between her legs was a rounded hill with a slight furrow at the bottom. Holding his breath, he reached out to her pinched nipple, naked between her fingers and he touched it. She moaned at his touch, then opened her eyes in surprise. Sandy wanted to find out how far he could go with his sister. He knew she was something of a sexual prude, and if the Device would work with her, it would probably work on anyone. He figured that this was as much as would happen, but decided to give the Device one more chance. As Sammy started to remove her hand from her panties. he kept one hand on her nipple and with the other secretly activated the Device again. She sighed and closed her eyes, then began stroking down her smooth skin towards her panties just as the next jolt caused another little shiver, raising her another level in sexual arousal, then he felt another shiver and then a third, each two seconds apart, just as he'd programmed the Device. Her fingers had returned to her pussy, slipping down over her thin underwear. She started to slowly run her finger up and down over her slit, looking at him with half-closed eyes. Then, sighing, she slid her hand inside her panties and began stroking herself again, up and down. She closed her eyes, murmuring that he should really leave now, but her hands reached out to him as if to pull him closer. Sandy was amazed. His older sister, the ice maiden, was openly masturbating right in front of him. He watched for a few seconds then switched the Device off and pulled his tee-shirt over his head, thinking he would lie on the bed with her and feel her tits pressing into his chest. He wondered if she'd really let him do that. He checked to be sure her eyes were still closed, then decided to give her one more jolt, just to be sure. "Where else does it tingle?" he asked, his fingers resting on her stomach right above her panties as her body tensed with the next oscillation. He could feel the heat coming from her pussy. "Oh God!" she sighed, feeling his fingers. "That feels so nice! But we shouldn't be doing this. Oh Sandy, we shouldn't!" Her hands moved to his near her crotch and he thought she was going to push his fingers away. Her hips were making involuntary up and down thrusting movements, very small but still perceptible. Suddenly she cried out, "Oh YES! YES!!! Right here!" Sammy let one leg fall off the side of the bed, exposing the strip of panty material emerging from between the globes of her ass and covering her mound. Her brother could see her rear pressing against the bed and could make out a stain of liquid spreading from her crotch through the material of her panties. He saw her ass contract with a quiver, and realized the Device had cycled again, beginning another series of transmissions. She traced her fingers around the edges of her panties, sighing again with sexual excitement. Sandy lowered his hand until his fingers were resting on his sister's panties, right over the apex of the vee of soft hair, then traced down the narrow furrow between her legs. He could feel her pussy quiver, once every two seconds as again and again the Device worked its magic. He lightly drew his fingers upward, keeping a slight pressure as he felt the soft mound of her sex through her damp panties. He used his fingers to squeeze the sides of her flesh together, as she had done, and again she moaned, spreading her legs wider to give him access, arching her back. Sammy's body shook as his finger touched a small button of flesh and her eyes flew open, almost in shock. She gasped as she saw her brother had removed his top, but then reached up and rubbed her hand over his chest, tickling his own nipples. He started to take his fingers away, but his sister reached down and firmly pressed them against her flesh again. He realized he had found her clitoris and pushed against it. Sammy began to press her hips upward, forcing her pussy against his hand every time the Device pulsed. Little cries of pleasure began to escape her lips with each pulse. She put her hand right on his, pressing his finger down hard against her panties. Sandy hooked his fingers under the elastic waist of the panties and slid them down over her hips, exposing her fluffy patch of blond pubic hair. Sammy urgently lifted her hips off the bed, allowing him to slip her panties down her hips and he could smell the wonderful smell of cunt as he returned his finger to the magic spot. The soft blond hairs below her pussy mound were wet and matted against her white flesh. He kept one finger on the tiny button of flesh and slid the other ones down deeper between her legs, parting her moist slippery cuntal lips. When she felt her panties being removed, Sammy couldn't wait any longer. As his fingers pressed into her most secret recesses her own hands flew to her brother's jeans and fumbled with the buckle. She tugged at the belt which opened suddenly, the snap at the top of his jeans popping open at the same time. Sammy yanked down the zipper and pulled her brother's jeans down his hips. His cock popped out, stiff and straight, and she curled her hands around it, murmuring softly to herself. Sandy was so excited he barely remembered to make sure the Device was off. It was. He let his fingers trace back up her thighs and she moaned yet again, spreading her legs far apart, giving him a view of her entire naked pussy. The sides of her pussy were bright pink and he could see wet lubrication as her hole opened to him. He touched her exposed cuntal hole and found it was squishy wet, fluid almost dripping out. His finger slipped between the lips again, going deeper this time and her whole body jerked with pleasure, her hands giving his erect organ a hard squeeze as he felt her cunt squeeze his fingers. He could feel a membrane blocking his way and knew for sure that his pretty sister was still cherry. Without removing his fingers Sandy stepped out of his bluejeans, pulling off his sneakers with his other hand. He drew his finger up the furrow of Sammy's wet pussy until he was at the top. A spasm of pleasure racked her body. With his thumb he experimentally flicked the button of flesh buried between her soft cuntal lips and was rewarded with another contraction of her cunt and of the fingers holding his erect cock. He kept up the rhythm of the Device, once every two seconds, even though his invention was switched was off, figuring she'd been conditioned to it. As if in response, his sister pulled him onto the bed with his stiff cock, urgently trying to fit him between her legs. She seemed in an awful hurry, but then lifted her head and touched each of his nipples with her lips, her eyes open wide and her hands still struggling with his hips as if trying to figure out how to jam his cock into her pussy. She began sucking on his nipples, her hips thrusting up and down now in bigger motions, faster and faster, about one every half second and she was groaning, telling him to hurry. Sandy climbed onto the bed. His sister never let go of his cock, pulling it to her open pussy as he lay naked between her legs. He felt a jolt of pleasure when his cock head touched her wet open pussy. Sammy rubbed the head of his cock up and down on herself, arching her hips on the bed and crying out with pleasure. On the next thrust of her hips he felt his organ slide between her wet cuntal lips, actually penetrating the slippery cuntal canal, stopping just at the entrance. Her fingers were around his cock, pulling it into her body and she kept murmuring "Hurry! Hurry! Oh put it in!. Put it in there!" He felt resistance. He couldn't get past her virgin membranes. She pulled on his cock, stuffing it into herself and he felt a sudden tearing sensation as he took her maidenhead, but his sister was too far gone to notice. He leaned forward, holding her and crushing her tits against him as his cock slid into his sister's cunt. It was so hot and tight he couldn't believe it! Sammy cried out again and again in pleasure as his cock slid right up into her hot pussy and he began ramming his stiff dick in and out, his crotch slamming against hers and pushing her ass down into the mattress. Her legs were wrapped around his ass, holding him tight inside her body. She was kissing and lapping his face again and again, and he responded, kissing his sister full on the lips for probably the first time in his life. He felt his cock slide against the tight wet flesh of her tight cunt again and again. In return she thrust her tongue into his mouth then sucked his own into hers, pressing her full firm tits against his body and rubbing them from side to side. He'd never even heard of a woman getting this turned on and he knew he was going to cum too quickly. He was afraid he couldn't resist shooting his hot sperm into her but he didn't want the experience to end. Sandy tried to pull his dick out of his sister's spasming quim, but she cried out almost in frustration, trying to get him back inside with her hands, her cunt squeezing him tightly inside her body, writhing on the bed and moaning with desire. He pulled her hands off his cock, seconds away from cumming, trying to think what to do next. Sandy used all his strength to hold his sister's hands away from his organ as he lifted his hips to pull his cock out of her tight pussy. He had to strain to pull against her powerful gymnast's legs, which were wrapped around his ass trying to pull him back inside. He fingered her clit again while he recovered, but she kept telling him to put it back in, begging him not to stop. He worked himself down her body and lowered his head to her mound. He touched her clitoris with his lips, running his tongue up and down her slit. Sammy almost shouted, saying "No! No! Oh please no!" but her back arched in response and her legs parted. He lapped up her slit, pushing his tongue inside her while she kept murmuring "No! No! Oh Please no!" But she still moved her hips up and down, pushing her pussy against his probing tongue again and again. When he thought he wouldn't cum immediately, he returned his cock to her quim. Sammy immediately changed her chant to "Yes! Yes! Oh please yes!" and he slid into her again, loving the tight feeling of his rock hard shaft inside her tight cunt. Again and again they fucked, his shaft sliding in and out of the tight pussy and rubbing right against the tiny button of flesh that was exposed by her widely spread legs. He could feel her pussy spasm around his cock and she bit the pillow to keep from crying out, holding his ass tightly with her legs and pushing his body tight against her. They fucked harder and harder, Sammy reaching one climax after another, impaled on her brother's cock. Finally Sandy pulled out just as his organ began gushing sperm which flew in thick spurts all over her flat stomach, wetting her blond pubic hairs. To his amazement, his sister was still thrusting her hips up and down, crying out in excitement, so he moved his body down until his lips were at once more at her open cunt and began lapping her clitoris. She immediately arched her back, lifting herself to give him better access, and spread her legs far apart. He thrust his tongue deep into his sister's hot wet crack. She cried out again and again as multiple orgasms swept through her. He sucked and lapped, tasting his own cum and her fluids, a tangy unfamiliar taste. She kept climaxing, again and again, wrapping her legs around his head this time to keep his mouth close to her spasming cunt. As his jaw got sore he wondered if maybe he hadn't overdone the Device a little. She squeezed his head with her thighs, raising her knees in the air and his ears burned from the friction. Still she wouldn't let him stop, crying out again and again. Finally she collapsed on the bed, unable to continue any more, her hands still working at her own pussy, gently pressing it and exploring as if to see if anything was broken. He could see she could feel his wet sperm on her pussy hairs and she lowered her hand to her open cunt, then pulled her fingers away. Sandy sat up in the bed, between his naked sisters legs, rubbing his sore ears. He was amazed at the effect his Device had had. It passed any expectation! He realized that his prick was sore. He guessed the last few jolts he'd given her hadn't been necessary, and decided to put an automatic shutoff control on it, just in case he forgot. His sister was recovering. She began sobbing with confusion and exhaustion, saying she was sorry, and that maybe they better get dressed. He was a little relieved, because he wasn't sure he could do another round of fucking right now. He watched his sister roll over on her stomach, crying into the pillow. Sandy supposed he should feel guilty, but his eyes roved over her supine form, noticing the smooth curves of her tight buttocks and thighs, and he stroked lightly up her legs, telling her it was all right. "No it isn't," she sobbed. "God, I never let anyone even touch me there, and now we've done it all the way! What could I have been thinking?" "Maybe it isn't our fault," he lied, still gently stroking her smooth ass cheeks. To his astonishment, his prick stirred in response. Not now, he thought. Down boy. More for you later. He gave her the story he had invented. "Maybe it was that goo I mixed up, like maybe it was stronger than I thought, and we got carried away because of it. But I'm not that sorry. It was the most wonderful feeling I've ever had." Sammy rolled over on the bed, her teary eyes meeting his as she sat halfway up on the bed. Her breasts jiggled and he felt his cock twitch again, getting stiffer. She began talking softly, in a wondering voice. "Oh, I know! I just couldn't help myself, and it felt so wonderful! Soooo wonderful. Like fireworks and stars and so so good!." She looked down at his crotch and gave him a little smile. "At least I'm glad it felt good for you. And at least you pulled out before you, you know. . ." She reached for a box of tissues near her bed and turned her back to him, carefully wiping off the droplets of sperm he had shot onto her belly. Then she looked pained. "But I don't know if it was that stuff, you know. Oh God, Sandy. Lately I've been getting these, you know, urges. I asked you to leave, you know. I mean, maybe I'm becoming some kind of nymphomaniac or something. Like I have to do myself, you know, like down here, all of a sudden. And I just can't resist. I think I'm going crazy!" Sandy thought to himself. He didn't want to tell her about the experiments he'd been doing with her cat, or with the rats in the basement, but perhaps his coil had been leaking radiation through the house. He really wasn't sure what the effective range of the device was, and there had been several unexplained oscillations while he was testing it. Maybe Sammy had been in the basement, doing laundry perhaps. "I bet it's the chemicals I've been playing with," he lied again. "I've been having the same effect, but I thought I had diluted them enough this time. I've been thinking about how pretty and sexy you are, and how incredibly sexy your body is, for weeks, and even fantasized doing it with you. Maybe I should pour the stuff down the sink!" Sammy laughed ruefully. She covered her naked breasts with her hands. "And turn on everyone who walks by a sewer? Oh Lord, Sandy. What're we going to do now? I mean what if Mom and Dad ever found out?" "Hmmm," Sandy said. "I wonder if they've noticed any effect? I mean, the fumes of this stuff must have leaked out, you know. I've been noticing that I get pretty horny too, but I figured it was just being a boy, you know?" "Now that you mention it, they have been going to bed earlier." Sammy almost laughed. "But you know they ARE married. Do you really think that this all is because of some chemicals?" She waved her hands over her naked body, then realized she was sitting talking to her brother stark naked. She pulled the bedclothes around herself. "It seems that way. I mean, you ARE the most beautiful girl in school, and it's not like I'm not affected by that, but I don't think this ever would have happened if you hadn't sniffed that goo. Or if I hadn't." "Uh, Sandy, do you think you could go now so I could get dressed?" "Okay. Let me get my stuff." Sandy picked up his jeans and underwear from the floor, pulling them on. He noticed that his sister watched him dress, not taking her eyes away when he tucked his semi-erect cock into his undershorts. Maybe a residual effect of the Device, he thought to himself, pulling his tee-shirt over his head. He pulled on his sneakers and stood up. "You better hurry," he said, looking at the clock by her bed. "Don't you have cheerleading practice today?" "Oh no!" Sammy exclaimed. Then she looked at the clock. "I've still got thirty minutes. Enough for a quick shower. God knows I need one. Is my hair a mess?" Sandy laughed. "Just a little. You look really beautiful, you know. Really!" Sammy blushed. "Just let me get up. Oh damn, I don't know what I'm doing! Where did all my clothes go?" Her brother handed her her panties and bra. He realized that the panties were still wet in the crotch, and slick. "I don't think you can wear these," he commented. "No, I guess not. Oh Sandy, what have we done?" "Better get ready," he said, rising from the bed, not wanting to answer. "We can figure that out later." He left the room and heard her getting out of bed. In a few minutes she came down to the kitchen. He'd poured her a glass of juice and toasted an english muffin, which she grabbed. She was wearing her cheerleader outfit and brushing her hair. She asked him, "How do I look?" "Still beautiful," he replied honestly. "How do you feel? Any dizziness?" "No," she said thoughtfully. "I feel embarrassed, but that's all. And a little tender down here, to be honest. Really, a LOT tender. How do you feel?" "A little stunned and sort of tired," he replied, still being honest. "And a little sore myself, I guess. I just want to make sure you're okay to go out." "You mean I won't grab the first man I see?" she replied ruefully. "Well, I don't feel anything like I expected to. Just sort of rosy and calm. It's really strange! But I don't think there's any danger. Besides, going out is probably safer than staying home, you know?" "I guess," he replied. "If you feel anything strange, I mean anything at all, you better call me." She made a face at him. "I think you've done enough for me this morning. Why aren't I angry at you, damn it! Like I said, the whole thing felt so good that I still don't know what I'm saying." There was a pause. "Look, I've got to get going. I guess I should be glad I didn't sniff that stuff and then walk outside, you know?" Sandy laughed. "I know. Okay. I'll find some way to get rid of this stuff. Maybe burn it. Or mix it with some acid to break it down." "Just be careful with it. Keep the stopper on!" She went to the door and opened it, then turned to him, blushing. There was another pause while she smoothed the short blue skirt of her cheerleading outfit. She looked a little uncomfortable. "Look, Sandy, um, don't do anything with it until we talk some more, okay?" She didn't wait for a reply, just ran outside. When she was safely down the street, Sandy let out a whoop of glee. The Device worked! There was no doubt about it. He was a sixteen year old boy with a full life ahead of him, no doubt about it! He returned to the basement and checked on the rats, who were soundly asleep. He ruefully rubbed his own pecker. It was sore from the hour of hard fucking. He walked back up to his room and pulled out his list, crossing off a few names and adding his pretty English teacher, putting her near the top of the list. He thought another minute, ruefully rubbed his sore cock and added his older sister's name, right at the top of the paper, underlining it twice. He was sure that this experience wouldn't be his last with her hot tight cunt. Sammy worried that the effects of the Device would last longer on humans than on rats. He knew that the rats' fucking lasted only a few seconds, and he and Sammy had gone at it for at least an hour. He realized he didn't even know if that was normal for human teenagers. Maybe his sister was still having after-effects. She'd seemed all right when she left, but still. .
