This is my second story post. I hope you like it. I've plans for at least another 3 chapters.

Invisibility

Chapter 1 - Trials and Tribulations

Steve was invisible. Hard to believe I know. But a statement of fact nonetheless. There he was standing in the high street, people moving around him, and if you looked through his eyes, you’d wonder what all the fuss was about. He could see everyone else. He could see his arms and legs. He could see his shadow falling on the pavement behind him. Seen from a stranger’s eyes though, there was nothing there. You’d be walking down the pavement, not paying attention, avoiding people you could see, perhaps noticing the odd shadow of a man there in the middle of the street with no-one to cause it, perhaps not. Not until you bumped into someone though. The words “Sorry” already out before it dawned on you a few steps later that there was no-one there. Stopping and turning around in confusion, and then shaking your head and continuing down the street.

It had always been a dream of Steve’s. He was too conspicuous as a child, especially to his father who always thought Steve was in his way. Tying him to a marriage he didn’t want, a job he hated, he took his frustration and anger out on his son, frequently beating him for leaving toys around, for poor grades, for just being there. Steve’s ardent wish for invisibility had become the germ of an idea which drove him to study biochemistry, genetics, and particle physics. As soon as he could he ran away from home, working his way through university, getting his first then second degrees. All the while working in his own highly specialised lab in his basement. A lab second to none in his field. A lab in which at last he had made his breakthrough.

Combining esoteric theories from his specialities, he wove them into a new and exciting discovery. That transparency of any object, organic or inert was changeable. Indeed that it could be modified quickly and specifically. Testing began on inanimate objects. He whooped with delight when a small stool in his lab stood first solidly on his bench, then tuning his device, he was able to make first the legs, the seat, and finally the screws and brackets holding it together disappear. Next came a rabbit he named Harvey after James Stewart’s invisible rabbit. At first nothing happened. He searched the entire spectrum looking for the resonant frequency that would trigger the change. He sank back into his chair and thought as he watched Harvey munch on a dandelion leaf.

That’s when the real breakthrough happened. Because Harvey was living, his resonant frequency must be changing all the time. He had to synchronise his machine to change frequencies to match Harvey’s. A few modifications later, and he was ready for another test. First he switched on the synchroniser, hooked that up to the inputs of his machine, then switched on. Harvey slowly faded in and out of view, still munching happily on his leaf. His body was made invisible in nauseating waves; first his fur, then his skin, eyes, muscles, veins and finally bones and internal organs, phased in and out of existence. This was an unexpected return, but showed useful applications in medicine. Then suddenly the synchroniser locked in to Harvey’s body and he was suddenly gone. The leaf he was munching was flickering in and out of existence. It was gone when in contact with Harvey, and back when Harvey stepped back to chew his mouthful.

He’d done it. He sat back and sighed with relief. Switching off, he gave the now visible Harvey a hug, and set him back in his cage. Looking at his lab he laughed. First thing first, was to find a way of miniaturising his equipment. At the moment he needed a three phase supply and two 2m tall cabinets to house his equipment!

A few months later and it was done. By removing redundant and duplicate components, improving efficiency and finding a high powered rechargeable lithium battery source, he was able to reduce the whole thing to the size of a walkman. Worn around the waist under a shirt it was fairly inconspicuous, and when turned on would last for 4 hours before needing to be recharged.

Steve’s first test in the field went well. He switched his machine on, then went for a walk down to the shops. There, standing in the middle of town, people were moving all around him and ignoring him. There were moments when he doubted his own invisibility, especially when someone appeared to look directly at him, but he could prove it easily enough. By tapping them as they passed or bumping into them, they stood staring and confused because there appeared to be no cause. An unanticipated side-effect of being invisible was that he was sexually aroused. He wasn’t sure whether it was because he could see without being seen, something in his own psyche, or whether it was a mechanical response to the invisibility generator. It was all the same in the end. As soon as the field was switched on, he became aroused, wanting to expose himself to people, or to watch as they stripped off to change. The ultimate in people watching.

His first stop had been to go to the local pool, and slip past the doorman and into the ladies changing room without being noticed. He watched the women entering and leaving the cubicles, and then carefully climbed up so that he was standing on the partitions between them. Looking down he could watch while women dressed and undressed below his feet. At first this was arousing beyond anything he had experienced before, and started to stroke himself through his trousers. He rapidly got hard and uncomfortable, which led him to wonder why he’d bothered with clothes at all. Attempting to extricate his by now cramped organ from his pants nearly unbalanced him from his perch. Finally he managed it, and started to stroke himself, only to find himself getting more and more frustrated. Just as he’d settle in to watch an attractive woman, overcome his balance and watch as she stripped off blouse, skirt, then underwear, she would just as quickly put on a swimsuit and be out of the changing room before he had a chance to climax. Or he’d close his eyes for a second, and open them to find a granny, or worse, a schoolgirl changing below him. He had hoped to come across a couple of women getting more intimately acquainted in there, but it seemed that sort of thing only happened in his mind and in porn films.

Dropping from the partitions, he got closer to the communal showers. He watched as the women soaped themselves up and rinsed off. This was more like it he thought. He opened his flies and started to stroke himself again, rock hard and pulsing in his grip as he watched soapy hands rub over bodies soaked in the warm deluge from the showers. He was getting harder and harder, imagining the women being more sensual in their showers than they were in real life. Stroking their breasts and smoothing down swim-toned bodies, teasing at their pubic hair until finally diving into wet pussies, legs spread apart and leaning back to let the spray do it’s work. He was getting close and getting more carried away, daring to touch the closest woman gently as she showered before her confused gasps alerted the other patrons. Grabbing his pants in one hand he escaped to try something else.

He tried the ladies' changing rooms in his local shops but had no joy there either. They were generally closed at the top, so he couldn’t get in to see. And those he managed to spy on were either occupied by women that failed to excite him, or he went too far and they shrieked. He quickly realised that he would have to reassess the situation. Why was it that fantasies never quite worked out how you wanted them to in real life? He realised that he was a natural voyeur and got excited by watching other people when they thought they were quite alone. In the past he had enjoyed watching a couple who were kissing very passionately on a train one morning. They had those wild sex-crazed eyes that told him they were looking for a place to have sex, and soon. He followed them as long as he could before eventually losing them in the crowds, but not before catching glimpses of her briefs and bare breasts as they fumbled and fondled each other.

He looked to his own neighbourhood. He chose a young married couple who lived nearby. Not right next to his house, but close enough for him to be hanging around. She was in her 30s, tall, probably around 5’8”, and slightly taller than he was, with dark long brown hair down to her midback. She wasn’t slim, but she carried herself well, wide hips and bust emphasising her narrow waist. He’d always preferred his women on the curvier side. The first time he’d seen her, she was in her front garden wearing short khaki shorts and a halter neck top. He’d almost stopped walking to stare at her wonderful cleavage, before her “good morning” brought him back to himself. They hadn’t progressed beyond the odd “hello” whenever they ran into each other, although he’d got her name, Sarah. Sarah was married to Jim, an investment banker who worked long hours. It seemed to pay well looking at their house and cars. An Audi TT for weekends and a Saab 93 convertible.

He charged his generator and slipped it on, spraying himself liberally with mosquito repellent. Although he was invisible, mosquitos were attracted by sense of smell, and he was always being bitten by them. The evening was warm enough for him to be unencumbered by clothes. He put his door on the latch, leaving a spare set of keys outside just in case, and padded softly to Sarah and Jim’s home. The lights were blazing from their living room, and looking through the window, he could see they were relaxing in front of the TV after their dinner. He wanted a closer look though, so slipped up the side of their house, through the unlocked back door, making his way back to the front of the house. He thought he had been discovered when the door opened and Sarah walked down the hall towards him. He sank back to the side as she breezed past, wafting him with her perfume and making him instantly hard again. He stood there for a second breathing in the warm summer scent of flowers before continuing on his way and silently sinking to the floor in their living room. He’d positioned himself to the side so he would be facing Sarah’s chair, with Jim to the side facing the TV.

Sarah came back in the room with a couple of beers, popped them both, handed one to Jim and sank back into her chair, her summer skirt lifting over her knees as she sat down. Steve’s view was straight up between her legs as she leaned back and swigged at her beer. Between her slightly parted thighs, was a thin strip of white cotton. Steve, already erect, moved his hand down and started to slowly rub himself, feeling the sticky dampness of his excitement on the tip. His cock was hot in his hand, throbbing with excitement, in time to his heart which threatened to give him away, beating so loudly. He had never felt so excited in all his life. Still stroking himself, he stood and walked around the room, first standing next to Jim’s chair as Sarah spoke to him, his cock almost touching the man’s face. He was pushing his luck, but he was feeling all-consumed with lust and power, almost willing Jim to turn his face towards him. Then he walked silently over to Sarah as she reclined in her leather chair, her head turned to face Jim as they chatted. Steve stood directly in her line of sight with Jim and she was completely unaware that Steve was slowly masturbating his cock millimetres from her lips. Steve was so close to the edge, watching her lips open and close so near to him. He thought she must be able to smell his desire and arousal, but she continued talking. He was so wrapped up in his own excitement that it was only then that he noticed what they were talking about. They were flirting with each other. She was telling him of one of her fantasies, and he was lying back stroking himself through his suit pants. One of her hands was resting between her legs, lightly stroking up and down, and the other sliding up her body to cup her breast, her nipple firm against the light cotton.

As he watched her, she ran a finger around the little nub, and then tweaked it making it stand out harder against the dress. Steve was besides himself now and stopped stroking himself, needing no more stimulation. He wanted to see what happened, and didn’t want to come prematurely. Jim had unzipped his pants and pulled out his cock, sliding a hand up and down the shaft and pumping it up to full height. Sarah had slipped a hand inside the top of her dress now and was cupping the bare breast directly. She was clearly getting more involved with her story as her dress was up around her waist now, fingers stroking outside of the now wet cotton covering her crotch. Steve had to quickly leap out of the way as she suddenly sat up and leaned towards Jim, slipping her dress off her shoulders and offering him her breasts. If only she knew how close she had come to swallowing Steve’s cock twitching with excitement right next to her face.

Sarah stood up, letting her dress drop to the floor and languidly stretching her arms overhead. Steve was paralysed with lust, finding his ideal woman standing before him. Her breasts pulled close to her as she stretched overhead. She reached over to Jim, pulled him to his feet, and dragged him through to the bedroom. Steve stood to the side of the bed, hand once again on his cock as Sarah relaxed back on the bed, arms overhead, legs spread wide, drawing Jim towards her. Kneeling between her legs, Jim brought his lips close to her cotton clad pussy and licked slowly upwards. Sarah shuddered as the cotton sank between her lips. Jim pulled her briefs off, and unknowingly tossed them at Steve, not noticing them hit his body and fall to the floor at his feet. Steve picked them up, sniffed them, then wrapped the warm damp cotton around his cock and resumed pumping himself.

Jim got back between her legs, licking once again slowly from bottom to top. This time his tongue plunged into her, scooping out her juices and drinking them down before slowly licking up over her sensitive clit. She gasped at the tortuous speed of his tongue, wanting it faster, ready for him, not needing to be teased, and yet loving the attention. Over and again his tongue licked from bottom to top, top to bottom, swirling around and diving deep inside her. Slow strong licks getting steadily faster as her excitement built and built again. At one point plunging into her hot wet folds, mouth wide to cover her entirely, at another flicking over her engorged clit, hard under his rough tongue. Faster and faster he went. It was too much for Steve who suddenly found he was coming, his cock pulsing and spewing thick white cream. The first blob landed on Sarah’s chest, just below her nipple, before he managed to get under control and finish on the now soaking briefs. Stroking himself in time to Sarah’s gasps he panted as he came over and over again. He looked back in time to see Sarah bucking up and arching back as she came, pulling Jim’s face deep against her, his tongue still flicking over her clit as she jerked and shook in passion. Steve continued to stroke himself and wondered that he could maintain his erection, his cock stiff and aching in his fist, begging for more. Sarah finally sank back on the bed, gasping for breath, pushing Jim away so she could recover. She hadn’t noticed in the thick of her excitement that Steve’s come was drying in her breast.

Quickly Jim stripped off the rest of his clothes, and pulling her hips towards the edge of the bed, positioned himself at her aroused pussy, his cock throbbing with red heat. Steve was in two places at once. He was standing to the side of the bed watching Sarah about to get speared with Jim’s cock, and he was there, cock poised, hard and ready to plunge deep inside her. Mimicking Jim, he thrust forwards in his fist as Jim drove deep inside Sarah. Again she arched back and writhed in lust as he sank inside her. Jim and Steve stayed there for a second, relishing the pressure on their cocks, then gradually withdrew, slowly, inch by inch, until just the tip was inside her. Steve was almost ready to go again, he couldn’t believe how excited he was. Jim paused a second, then thrust deep again, Sarah gasping at the oh so welcome intrusion. Again Jim withdrew, and faster now, he drove back in. Out and in, not waiting, not allowing Sarah to recover before plunging back in again. Their pubic bones pressing against each other with each thrust. Grunting now, they pulled against each other, bodies slapping together and building towards a mutual climax. Steve matched himself to them, his fist hard on his cock now, stroking himself with the same crazed lust and violence he was watching. Harder and harder they went, grunts turned to groans and screams, desperate for release. Wanting it so badly.

Sarah came first, she let go, arched back and pushed back onto Jim driving him deep inside her as she came, her pussy milking and squeezing his cock triggering his own release. He started to pump his come deep inside her with a great shout. Steve quickly followed, his cock starting to twitch then with a final stroke, he soaked the briefs a second time. The room with heavy with the gasps and sighs of the Jim and Sarah and thick with the smell of sex. Jim collapsed down onto Sarah, still buried deep inside her, kissing her and holding her close, inadvertently smearing Steve’s blob of come between them. Steve sank down on the floor and recovered his breathing. He cleaned himself up delicately with the briefs, his sore cock protesting as it slowly subsided away. Dropping the briefs on the floor as a present, he padded softly out of the room, let himself out, and went home. He put his generator back on its stand to charge, and sank down on his bed and drifted off to sleep. His last thoughts were of Sarah and Jim and the moment he had shared with them. The powerful exhilaration of watching them at their most intimate moment. Of standing so close to them while he came so powerfully. Of his rogue come splash on Sarah’s breast that they thankfully didn’t notice. Of the cum drenched briefs on the floor that they would notice later. He wondered if they would realise they were soaked with someone else’s come. He thought of his come carried around in her briefs, and being worn so close to her pussy. That thought made him smile and his tired cock twitched in response. He wanted to do it again, and soon. He was addicted now. He wondered who else he could watch…
