Chapter 2

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.
