16 year old Evan Reese sat in his physics class the second semester of his junior year at James J. Edgerton High School in Buena Aliso, California and his teacher was about to announce the theme of the student's class project. "Shit, this is going to be a pain in the ass," he said to himself, as he yawned in his seat. while his teacher, Mr. Tittle, was at the point of talking about the percentage of the grade it would be and what the research guidelines were for it (which was a fancy way of him warning against plagiarizing stuff they found on the internet). "So here it is kids: your project will revolve around the properties of light refraction and the possible practical applications of it for the future. This will require you to really use your imaginations here. Let's see some innovative stuff," he urged. "What the hell am I supposed to do with THAT?" Edwin asked himself. "This is going to really challenge my bullshitting capabilities."

At lunch, he griped about it to his twin sister, Yvonne, who reciprocally complained about her class' project. Being twins, they were very close to the point where, even though they had their own rooms, she often went into his room at night to sleep with him. Their parents tried and tried to get her to stop doing that, but gave up because she seemed to have such a great need to have him cuddle her at night. And, just as a precaution, they put her on birth control after he had a wet dream one time when they were 13 and ejected a ton of semen. They never had sex, though they had occasionally made out and manually stimulated each other.

Where they lived, the marine layer that came in off the ocean often manifested itself as fog and while it didn't get pea soup thick, it could get somewhat opaque at times when viewed over a certain distance. This gave Evan an idea. He and Yvonne went outside to the main street off the cul de sac they lived in and he stood there and holding a flashlight while having her walk down the street and stop when she couldn't see the light anymore. They also noted the lights from the passing traffic and how those beams were refracted by the moisture from the fog.

Evan wondered if he could do something to boost the efficiency of the bulb in the flashlight and make it so that it would be more penetrating under foggy conditions. That could then perhaps be applied to headlights. Over the next two weeks, he worked on it and worked on it. Of course, there were going to be inherent limitations because batteries can generate only so much power and they weaken the more one uses them.

He and Yvonne went out with his new revised flashlight on another foggy night. Unfortunately, if it wasn't any more penetrating than a normal flashlight. Then it happened: as Yvonne was walking back toward him, he shined the light right in her face from about 20 feet away. She stopped dead in her tracks and a blank expression crossed her face. Evan thought that was weird. After 30 seconds, she resumed walking toward him. "Why did you stop?" he inquired. "I don't know. I remember walking back toward you and that's about it." Evan recalled that she stopped when he shined the light in her face, so he did it again and there was that vacant look on his sister's countenance. He waved his hand in front of her face and she didn't flinch. When 30 seconds had passed, she came out of it and shook her head as if clearing cobwebs out of it. "Are you okay?" he asked. "Yeah, I think so. Boy, that was weird." "Stand right there, Yvonne. I want to check something with the flashlight," he requested. "Okay," she agreed. He put the beam of light right back in her face and she she stood there limply again. "Let me play with your pussy, Yvonne," he directed. He reached between her legs and manipulated her groin over her pants as he stood right up in her face so that his body screened off anyone who might want to determine what they were doing. The 30 seconds passed and she was still allowing him to rub her cunt. She could feel the wetness and excitement accumulating inside her. She didn't move a muscle to stop him. Her breathing was shifting into panting. Evan, worried that their parents would come out to see where their twins were and find him molesting his sister, stopped and suggested that they go inside.

They stayed up late as usual, long after their parents had gone to sleep. They changed into their sleepwear in front of each other unashamedly since they had been doing it since they could remember. To prevent any distractions, he grabbed the remote control and turned the tv off. He then retrieved the flashlight and shined it in Yvonne's face and she fell to back on the bed like a sack of potatoes. "Yvonne, from now on, you will like sucking my cock and the taste of my cum," he intoned. When the half minute had expired, she came to again. Evan pulled his cock out and asked her to lick it. She meekly scooted over to the side of the bed to get close to it  She had never sucked him before and hadn't been attracted to the thought at all, but she enclosed her lips around his flesh pipe and  bobbed her head up and down to make her lips glide over his shaft. Evan was super aroused as he watched his younger sister (by four minutes) milking his fuck stick and gulping his precum into her stomach. His cock got increasingly sensitive as he felt the weight and heat in his balls mount. "Shit Yvonne, I'm going to cum!" he blurted in a strangled whisper and then launched ropey strands of his sperm filled fluid into her yapper. He wondered if she would be mad or spit it out, but once she pulled away from his penis, she took every drop down. "God Evan, your cum tastes really good!" she smiled. "I'm glad you like it babe," he replied and he got into bed and cuddled her like he always did. He snuck a peek back at the flashlight to confirm that  he had turned it off after he had used it on Yvonne.

Yvonne nodded off and as he laid there holding her, he was asking himself a lot of questions about what he had just observed. The biggest for him was how long the flashlight was going to last. Also, when the strength of the batteries waned, how would it affect the trance the subject went into? Could he miniaturize or even recreate the device again or was this a one shot deal? Having to haul around that big ass flashlight all the time would be too conspicuous and kind of burdensome. He wanted to ensure it didn't fall into the hands of anybody else. He proved it could work in a bedroom at night and outdoors in the evening, but what about during the day?

The interesting thing, too, was that Yvonne gave him the hummer even after she had refused God only knows how many times before to do it for him. Having seen hypnosis used as a plot device in cartoons a few years ago, he got curious and read up on it and understood that even under a hypnotic suggestion people aren't going to do that which violates their value system. So there was something in the light beam that disrupted that value system, or so it initially appeared, when it came to his sister. He was going to have to test that further.

When he woke up the following morning, it was still faintly dark. His parents were both up and about to leave for work. He brought the flashlight downstairs with him and cornered his mom. When he cast the light in her face, she appeared to be in a trance and he ordered her to never, ever go into his room without permission, no matter what noises she heard coming out of there. Then he did the same with his dad. He went back upstairs and Yvonne had just come out of the bathroom after primping for the school day. He inserted a suggestion into her mind to never touch the flashlight again without his say so. But to make even more sure, he hid the flashlight behind a bookcase.

When they got home after school, he took Yvonne outside to test the efficacy of the flashlight on her in broad daylight. It didn't work. The rays of the sun just made the beam from it too diffused. Yvonne wondered what the hell he was doing playing with a flashlight outdoors at 3:30 in the afternoon. "Shit," he lamented.

Once his family ate dinner, Evan told Yvonne to come up to his room because he wanted to show her something he found online. He ran up the stairs while she casually strolled up them, so he was flashlight handed again and he had the light in the room off when she opened the door. He hit her with the light beam again. She froze. "You will obey every order I give you, including those that involve sex," he announced. He clicked the flashlight off and waited for her presence of mind to be restored. "You okay sis?" he asked with a smirk. "Yeah. I think I just blacked out again. I wonder if I need to go to the doctor for this." "Nah, don't go to the doctor and don't tell mom and dad, either. You're fine." "Okay," she assented. "Now get those clothes off," he smiled. She looked at him weird for a second and then pulled her tank top off and jerked her tennis shoes off. Next, were her jeans and now she was down to her panties and bra. "Stop right there and stand at attention," he desired. She gazed longingly at her cute, slim and bespectacled 5'6" 120 pound body. She was used to him touching her, so when he groped her ass through her panties, she barely reacted. But it did make her wet. "Okay Yvonne, lose the bra and panties."

Evan had tossed his own apparel aside and was boasting a solid six inch hard on that was already dripping precum  He climbed into bed and told her to join him. "Please take it slow, she pleaded. "Don 't worry Yvonne. You know I love you." "I love you, too, honey," she echoed. They always had that affection for each other but were convinced that as long as they weren't fucking each other that it wouldn't be incest. This was even though Evan had been eating her over the last two years and knew precisely how to pull her trigger.

He enveloped her in his arms and he kissed her gently while caressing her left  check with his righthand as he enjoyed the feeling of her warm skin on his. "I've wanted to do this for such a long time," he softly disclosed. "Me, too. I know it's wrong,  but I want you so much," she said in a very sincere tone of voice. He lightly felt her breasts up and her nipples extended stiffly, inviting him to suck them. His hand slid down her abdomen to her pussy, which was guarded by a thatch of light brown pubic hair while his suction pulled and distended her milk ducts. He trailed a finger up her slit and it was instantly splashed by her lubrication. He brought it up to his lips and licked it off. "You've always tasted so good, Yvonne. I'd like it if you would stroke my cock," he verbally nudged. She encapsulated his pole with her hand and he moaned as he felt it travel over the surface of his seemingly about to burst prick. He went after her nipples with gusto and kept at them for a while, her pussy making obscene sounds as he flexed his fingers inside of her while rubbing her g spot with the heel of his palm. She felt the fire building inside of her, her face and upper chest becoming flushed and her clit pulsing. His ears rang with the music of her moans and he was also doing some moaning of his own, his precum making it easier for her hand to slide over his hot, plumping penis. Oh fuck oh fuck, I'm going to cum, Evan," she rasped as she panted and gasped. He increased the tempo of his manipulation of her sex and she let out a long angelic sigh before she emitted a string of curses while the lightning of the orgasm surged through her.

Then she finished him off, wrangling his rascal to a roman candle like orgasm, his cum spraying her, him  and the bedsheets between them. He clutched her body tightly while they took a little break to recover from the drug like euphoria they helped each other experience. "I'm so glad to have a sister like you, " he whispered into her ear. "I love my big brother so much," she retorted.

When his energy was replenished, he insinuated himself in between her girl cum smeared thighs and lapped up her juices for a couple minutes before going after her clit. He sucked on it like he had her nipples and kept her body shuddering and her pubic muscles spasming for the next 40 minutes. He slid himself over her and told her to guide him into her pussy. She held it in her fingers and pulled it toward her opening. He leaned into her and it popped through her entrance. She sucked air through her teeth when his shaft had just began to penetrate her, his cockhead pushing her vaginal walls apart. He stopped. "Tell me when you want me to push some more of it in," he demanded. She tried to relax, but knew that the next stab was going to really hurt. "Just get it over with, Evan," she finally said. He slammed the rest of his dick into her all at once, shredding her hymen and her vaginal walls seeming to panic at the intrusion. He held it inside of her for a minute and then gingerly began to thrust. She twisted in agony as his cock raked her tender pink kitty. "Shit, she's tight," he assessed in his mind. He didn't like seeing her in pain and hoped she would be experiencing better sensations ASAP. Ten minutes later, she moaned and the moans escalated from there, enabling him to really rev his hips up for a good sorting out and he felt her fingernails pressing into the skin of his back while the pleasure asserted a stronger hold on her nervous system. "Oh shit, oh God, oh my God!" she gasped desperately, the accumulating heat packets that migrated up the network of nerves of her body destabilizing her breathing until she unleashed another fusillade of pants before the orgasm took the anchor leg. He was driving his spear forcefully into her over and over and she reach nirvana again before he released a torrent of boiling jizz that would defile her previously tidy cervix. He got up and switched the light off before plopping himself next to her and pulling her on to his shoulder. "So do you want to be my wife, babe?" he wondered. "I wish I could," she fantasized. "Me too, Yvonne. I feel like there is something missing when you aren't with me." "I know what you mean, Evan. That's why I don't really date. It takes away from the time I can spend with you." "I hear you, babe. Even when I feel lust for other chicks it's hard for me to imagine devoting that much time to them because it limits how much I can be with you."

"So what do you think mom and dad make of us always being so lovey dovey with each other?" "I think they found out they don't have any say in the matter, babe. We are half of one another and we have to stay together to feel whole." "What do your guy friends say about me always tagging along with you?" "You mean aside from the fact that they want to fuck you? I think they're okay with it. Nobody has said anything really negative about it." "That's good, I guess." "I wish you liked sports more, though." "Yeah, that isn't happening sweety. Sorry." "It's cool. I don't want to force you to do anything you don't want to. By the way, are you feeling any pain, Yvonne?" Yeah. But I can deal with it."
