Author: Siscentis Title: Halloween Transformation Part: 1 Summary: It's Halloween night, when Betty's brother transforms into something only she can tame... Keywords: inc, mf, cons, oral, magic Copyright by the Author, 2016 ------------------------------------ She stared at the back of the door, palely illuminated in the light from her small bedside lamp. She so rarely bothered to close it that the contours of the back looked strange; the whole section of the room put out of balance. Even after four years, she never quite felt ready for this night once it was here. She forced a deep breath, trying to calm herself, stifling back a quiver half-way through. She straightened a wrinkle out of her shirt, knowing it was pointless. The t-shirt was old, going back to high school. It had been a favorite for years, and had the worn-out appearance to prove it. It was soft, comfortable, and thin, full of holes and personality. She felt a little sad for it. She knew she'd never wear it again after this night. She drew in a sharp breath and froze, staring again at the door. He was getting closer. Even through the door, she could feel his presence, the weight of his steps as he moved down the hall. He approached, stopping just beyond the door. She waited for it to open, for those eyes to come through, staring at her. The steps started again; he was moving away. She started breathing again. Not yet, then. Not yet, but soon. She wasn't sure if she was glad for the delay, or if she'd prefer to simply be on with it. She again focused on her breathing and tried to calm the nervous energy. She heard distant voices from outside her window, echoing into the apartment's courtyard from another unit or the parking lot. There was always plenty of noise on Halloween night, especially in a college town. It had always worked in their favor, as it meant any stray sounds they might make were more likely to go unnoticed or ignored. She couldn't have chosen a better night for their annual event. She got up off her bed and went to the window, splitting the curtains and pulling up a slat of the blinds just enough to peek outside, checking again that no one was in the immediate courtyard. The action was automated, as her mind was elsewhere. She knew there was nothing but to wait. The process always just took as long as it did. She wondered if it was actually slower this time around or if it was just her imagination. Perhaps this year she should start taking the trouble of noting exactly what time he was ready. She glanced at her clock. 8:23. She sat back on her bed, doing a few quick yoga poses to settle nerves and keep her body limber, particularly focusing on her hips. Her brother had arrived early in the evening. Betty suspected he'd skipped his classes this time. As had become their routine on these nights, he'd come into her apartment with simple greetings, doing his best not to look directly at her or even engage her much beforehand. This time, he'd been a little more agitated, and she'd gotten him to talk a little in the time before sunset. He admitted he'd recently been dumped by his girlfriend, due to his emotional distance. Betty had always tried to convince her brother that his yearly issue shouldn't be a deal-breaker for his romantic life if they kept it under wraps, but she could tell his worry still caused him to keep girls at arm's length. As darkness had started taking hold outside, he'd moved into her small apartment's bathroom as it was the most secure place for him while it happened. Betty had gone to her bedroom to wait. The waiting was hard; it always seemed so long. She would try to soothe her nervous energy, relax and prepare her body, make sure the room was ready, but after all that, there was little to do but let her mind wander as it always seemed to back to that first time. It had begun when they were in high school, when Betty was a junior. Her little brother had just hit a growth spurt, and was starting to look something like a man instead of just a boy, and a quite handsome one to boot. Betty had found the development took her quite by surprise. That Halloween had started like any other. It had been a weekend, in fact, giving them more time to goof off and be bored during the day. When evening fell, she'd taken him to a party at his friends' house, whose older sister Tara, in fact, had often taken Betty under her wing. In retrospect, his strange behavior had probably begun before they'd even left their house, but it wasn't until she saw him with a girl at the party that she really noticed it. Normally quite shy, Henry actually seemed to be trying to flirt. She might have chocked it up to hormones, costumes, and his generally starting to mature, but his demeanor had been so strange. He wasn't just being forward, which would have been out of character enough, he was down-right insistent. She diverted him a few times, but after each he seemed to pick out a different girl to try, his eyes becoming increasingly predatory. When he actually grabbed ahold of Tara by the ass, Betty had to push him to the car to get him away. She'd gotten him home, finding he almost wouldn't come inside with her, having locked onto a woman among the trick-or-treaters on the street. Physically forcing him in had failed; when she pushed him, he seemed somehow much stronger than his developing frame had always been in their normal sibling tussles, and she'd ended up rolling off him and falling onto the ground. It was only when her cheap plastic costume skirt got caught most of the way over her waist that his attention broke from his other query and she was able to coax him along. Inside, she'd soon started worrying if her selection of "Sexy Schoolgirl" as a costume hadn't ended up a mistake, as he continued eyeing her, even with the skirt back in place. She wondered how long it would take him, in his current state, to overcome the mental hurdle of it being his sister before he started making a move. She decided it might be best after all to lock him away for the night, and tricked him into his bedroom, obstructing the door with a chair. It soon became apparent that the trick wouldn't hold. His knocking and pleas to be let out shifted to pounding, handle-rattling, yelling, and kicking. Plastered against the far side of the halls and feeling the walls shaking, she quickly got the sense that he'd soon smash his way out if he had too. She saw only one solution to the predicament. He was absolutely consumed by a supernatural lust. If freed, he'd run out the door, unleashing an increasingly wild state on a street full of trick-or-treating kids and moms. If she left him in there, it was only a short matter of time before he'd break through the door or window and be out just the same. Out there, he'd assault someone, and quite possibly worse, before the police were called. Who knows how much damage he might do or how many people he might hurt before being brought down? At best, it could mean years of psychological treatment and jail time, and at worst, he might be shot dead on the spot. It was too much to imagine her little brother lying dead on the street. Just that morning, he'd been as normal and happy as could be. She knew she had to protect him, and saw only one way to do it. If she couldn't stifle his lust, she'd have to direct it somewhere it could be contained. Knowing what she had to do, she pulled the chair from the door and stepped back. The door swung open, and her brother stepped out. This boy she'd known for his entire life was clearly changed before her eyes. He was almost hunched over, stance wide, eyes roving hungrily. His clothes were torn in several places, including right down the middle of his shirt, so it was almost falling off of him. She could see now that he wasn't actually bigger, but still more of a presence, intense. He looked right at her, as desirous a look as anyone had ever given her. The doorbell rang, and his head whipped around. Betty could hear voices outside, including at least one woman's voice among the children. She could see his attention waver. She raised one hip and lowered her chin, stretching her arms against the wall. "Oh, Henry," she called, trying her best to put on her sexiest look. She'd never been one to use feminine wiles to get her way, and doubted how appealing she really been able to make herself in her ridiculous forced attempt, but it was apparently enough. Her brother turned his attention back to her, approaching. She backed away from him into his room, beckoning him, until she bumped into his bed and fell sitting on it. He stood right over her, looming down, more imposing than she'd ever imaging her little brother could be. She leaned back against her arms, chest up and legs a little apart, waiting for him to act. He hesitated, and for a moment, she saw the eyes are her little brother trying to look out of the beast. Still hungry, but mixed in was recognition, and fear. "Betty?" He almost growled. Hands quivering over her, he held himself back. She could see the turmoil in him, as he fought the urges for her sake. "Do it," she said to him. And so he had. After it was over, he had diminished, returning to normal, and despite her worries, she found herself not much the worse for wear. In the following weeks, Henry acted ashamed around her, at a loss to understand or explain what had happened. She just kept on trying to reassure him that it wasn't his fault. Things gradually got back to normal, and the incident was put behind them, for the most part. At least until the next Halloween. Just to be safe, Betty had suggested they stay home alone that night, and while Henry was adamant that it wouldn't happen again, he agreed just the same. With their parents gone to their own usual Halloween party, the two sat watching movies. Then night fell, and it happened all over again. The same lust, strength, wildness came over him, the same ravenous interest in every woman he saw, with only his sister to hold him in check. Betty's response had been the same. The next day, he apologized profusely, again at a loss to explain himself, though he remembered clearly everything that he'd done. She'd comforted him and tried to focus his energy on a plan. She was his older sister, and she'd protect him, even from himself, even if it meant repeating what they'd done every year. Seeing no alternative himself, having no clue as to what was happening or how to stop it, he was forced to agree. Ever since, on Halloween night, he'd travel to where she was at college, and when the transformation happened, she stood by, ready to help. She knew the shame he felt at what he was doing to his sister, but also the gratitude for what she'd been willing to do to help. If anything, it had brought them closer, as he knew he could trust his sister when there was nobody else, and she valued their bond. She knew the loss of control scared him, even if the phenomenon was reasonably contained and the only other person involved was someone he trusted completely. He had a few times wondered aloud to her why he of all people had this curse; she could only encourage him to make peace with the situation as it was, like she had. She hoped that he could forgive himself and allow himself some pleasure in the act itself, perhaps even a guilty thrill in anticipation. Sister or no, he was still a man, after all, and it was clearly enjoyable for him while it happened. However he felt, he only had to deal with it once a year. She was sure that in time he would come to accept it as a manageable part of his life. After all, it could just as easily had been once a month, during the full moon, perhaps. Now that they were both in different colleges, a higher frequency would have been even more of an inconvenience. Betty broke her gaze from the door and her memories of her brother for a moment. She stretched her hips again, rolling side to side and spreading them. Pulling her panties to one side, she pushed one finger at a time into herself, until with some difficulty she got the fourth one in. Before the last year, she'd taken a few weeks to prepare her body in a new way, using her fingers and other things to gradually loosen herself a bit. Without regular sexual activity between their yearly sessions, she'd found herself not quite physically ready for his forceful approach. The prep work had done wonders to reduce discomfort. This year, she'd gone a little bit further, using a cucumber with some effort over the last weeks to get ready. This would be the fifth time, though somehow it seemed like more. It was only one night a year, and, as she had tried coaching Henry, would be best set on the back burner of their minds the rest of the time. Yet it seemed to follow her constantly, even defining what she thought about herself at times. If she were being honest with herself, she'd let it become at least as much a hindrance on her love life as he had. The door creaked open. She'd missed him approaching this time, and in her surprise, she found herself inching back on the bed. He came in slowly, creeping toward her, more withdrawn than usual. His first glance was one of concern. For a moment, Betty wondered if something had been different this time, if the transformation had somehow failed. Then there it was. The look in his eye shifted as he saw her, as if the very sight of her was too much for him to keep under control. Each step toward her came stronger, until he was hovering over her, hands open, ready to grab her. For the first time since the first time, he hesitated, a glint of concern returning his eyes. She wondered why this time he'd been able to hold himself back, when every other time since the first, he hadn't. "Do it," she told him. He was on her, leaning into her body, gripping and squeezing and pulling her sideways to him, hands jumping from place to place to grab and sample, bodies rubbing together. Dissatisfied, he pulled away from her. Even knowing what was coming, modesty had forced her brother to keep on some clothes as he'd waited, even if just a light shirt and shorts. He tore them off his body, as an animal who had no clue had to remove them otherwise, leaving them in tatters. Free from the civilized burdens, he returned to her, hands at the ready. His hugely swollen cock rayed out from his body toward her, and she had the impression of it reaching out for just as his arms were. It had seemed monstrous to her the first time, and to an extant she retained that impression, though as time went by she'd realized it probably wasn't inhumanly so. Her only prior impression of her brother's penis was when it was limp early in puberty, and compared to that little boy he was now massive. She'd been rather surprised when she'd taken the time to peak on him another day after that first event and discovered it was always the larger size. She'd sometimes wondered if it was simply his natural size or if the spell had a long-term effect, after all. He leaped onto the bed, practically right on top of her, pressing her down and pinning her arms. She suppressed a natural instinct to push back, relaxing her body for him. She could feel him poking her around the waist and pubic bone, then on the inside of her thigh, pressing up into the fabric of her own shorts and panties. If he'd only found his mark, he would have entered her right then. Her clothes had succeeded in delaying him. She knew it wouldn't last. His weight pressed harder into her, hands holding her arms at the wrist and stretching them over her head. He thrust his crotch against hers, rubbing his cock between her legs, grinding it against her vulva and clitoris through her clothes. He lowered his chest to hers and his head to her neck, and she tilted her head the other way to give him room, feeling the strong squeeze of his hands on her forearms and letting her hips open wide. She tried to relax herself again, but could feel the tension tightening her stomach muscles and bit her lip. Whatever happened, she would just let it happen; whatever he might do, she would let him do it. Pressing his nose along her neck, he breathed in deeply, taking in her scent. She wore the same perfume she'd had on the first night, a scent she'd been unable to bring herself to use for anything else since. She kept the bottle all those years just for these particular nights. He breathed out hot below her ear, growling lustily as he did. His mouth went for her, his wet, hot tongue running on her skin. He moved his way down from the side to the front of her neck, and Betty rolled her head upward as he went to give him room. His tongue didn't lift from her until it struck her shirt. He raised his chest, leaving his cock pressed into her, and released her wrists, grabbing the collar of her shirt. She let herself sink into the mattress, leaving her arms exactly where they were and waiting for what was coming. With one motion, her brother ripped the shirt open down the middle, proceeding to yank, pull, and tear it until it was completely off her body. She was glad the shirt gave way as easily as it did, not catching or jerking her neck. He fell back onto her, hands to her arms, now just above the shoulder, and mouth right onto her breast. She gasped as he started sucked it, greedily jumping from one breast to the other every so often, as though he'd forgotten the other was there and had to have it immediately. He stretched his mouth wide to consume as much of her breast as he could, his tongue practically wrapping around each nipple in turn and twisting. There was no fighting him, and she had no intention of trying. His naked, impossibly strong body was grabbing, holding, thrusting against her, held back just enough not to really hurt her. She held herself still, encouraging her own body into relaxation while not resisting its own natural reactions and movements. Growing still more inflamed, if she thought it were even possible, he rose off her, the release of his weight causing her to lift bodily off the bed from her own upward pressure she wasn't aware she'd been making. He grabbed her by the waist, both hands at her shorts, and tore them and her panties together straight down. Elastic snapped and fabric tore. Her lower body shook with his jerking pulls, and she grabbed onto the head board for stability. Shredded, what remained fell free or was thrown away behind him against the wall, leaving her completely naked before him. She steeled herself, preparing for his penetration. Instead, he did something different than the times before. Staring at her exposed form, he grabbed her thighs and lifted them, dropping his face into her, and she quivered at his sudden contact. Putting his nose against and almost into her, he breathed in so deep she could feel the air rushing over her labia. Exhaling, his breath covered her whole pussy with warmth, even seeming to fill her up. She gasped again. His mouth was on her, lips pressed against her own, his wet tongue running all around her soft flesh. He seemed to simply consume her, completely unconcerned by the blemishes on her skin, her untrimmed pubic hair, or the extra weight she'd put on recently. He was pure male beast, and he wanted her, needed her just as she was. If anything, with his strength, the extra mass would be to her benefit tonight. His tongue found her hole and dove in. He may not have been bigger, or had a super-human cock, but when in this state, there were some definite physical changes. He was much stronger, his usually somewhat soft body morphed into a hard, muscled one, in places almost feeling like skin on marble, and more than ample to toss her around easily if he chose. What had really caught her off guard the first time, though, was his tongue, which, she would swear, was not only stronger, but seemed twice as long and more flexible than natural. It dove into her, deeper than she'd been ready to feel from it, rolling and flicking and twisting in a non-stop flurry of motion. She gasped and cried out, almost a squeak, and was again glad that no one that may be around in the apartments would give such noises a second thought on Halloween night. Suddenly, he jumped off the bed, carrying her hips with him. She was dragged off the bed, her head swinging down into his thighs with a thump as he held her upside down. He turned her around as easily as he might turn an office chair, making them front to front, and opened his mouth onto her again. He wrapped one arm around her waist to hold it at his chest, her legs splayed over his shoulders. She dangled upside down, her hair a tangled, waving mess reaching most of the way to the ground. She walked her hands to his hips, trying to steady herself in his hold. His tongue swirled around and penetrated her, his mouth wrapped around her vulva, slobbering and sucking in as much of her juices as he could. Her head at his waist, his cock shot out from him right into her face, rubbing her cheek, chin, forehead, as they moved. She held herself back from him a second, but it was a hard angle to maintain and still wasn't enough to escape his dick, which still reached her and bounced against her chin. Her lower body twisting above her, and she dropped back against him, trying to go to one side. Still, her face ended up against it, with her eyes right against his balls and his cock running along her cheek up past the corner of her mouth. He thrust against her, rubbing his dick against her face. Holding her waist with one hand, he pawed at her head with the other, pushing it into him while thrusting. It was clear what he wanted, even if he couldn't quite understand it himself. The alternative was to let him continue frantically thrusting into her face, undoubtedly harder and harder until he got his way. Sooner was better. She obliged. With his balls bouncing off her nose and brow, she pulled herself back just enough. Taking a deep breath, she caught the end of his dick in her mouth. He stopped thrusting at the new sensation, and she tried to stimulate him with her tongue as best as her limited experience allowed. He let out a low moan, almost frightening in its animalism, and thrust into her mouth. After nearly gagging at first, she turned her head partly to the side, taking his next thrust into her cheek. Her body swung back and fell forward like a pendulum as his hips leapt into her repeatedly. With his tongue deeply running in and out of her, his lower lip pressed against her just outside her clitoris, which she could feel being tugged by his suction. She tried her best to block out the powerful sensation of her pulsing body, focusing on using her tongue and lips to keep his cock in her cheek and away from her throat. For the first time she felt slightly concerned for her own safety, not just from the possibility of him uncontrollably slamming his cock past her tongue into her throat, but as he became more insistent, that he might actually cum while fucking her mouth. Having experienced his ejaculations the last few years, she wasn't sure if she could handle that. As if reading her very thoughts, he stopped and threw her, his dick popping out of her mouth as she spun and flew briefly through the air and onto the bed, almost bouncing off the far side. Before she'd even regained her bearings, he was on top of her, rolling her to her back and pinning her down. Then, he was inside of her. She squealed in sudden surprise as his cock rammed deep into her pussy. Wasting no more time, he pounded into her again and again. She tensed, momentarily overwhelmed, but then eased. Her efforts this year had paid off, as the weeks of prep work, along with his delay and other actions before getting to the actual penetration, had made her more flexible and better lubricated than on previous occasions. Even with his size and thickness, she had taken him in fully without the discomfort of dry scraping or the tearing that she always feared if one of these times she wasn't fully ready. She relaxed as he pounded. He dropped his full strong weight onto her, pressing their bodies together, her tits flattened against him. He wrapped his arms beneath her, grabbing the top of her shoulders from underneath. She let her hips fall open, and wrapped her own arms around his broad back and her legs around his thighs. She held on close, using her strength to control his angle of entry as best as she could while he held her in his powerful grip and simply fucked deep into her. He fucked on and on, tireless and relentless. By her ear, he growled and groaned, as beastly as before, but not desperate. He slid out easily and pounded back in, driving, balls slamming against her, bed inching toward the wall she'd pulled it feet away from hours before in preparation. For the fifth time in her life, her own little brother was fucking her, needed to fuck her. And she wouldn't deny him. He was in need, unable to help himself, and she would take him into her, let him satisfy his primal need with his loving sister's body. After an eternity of thrusting, he tightened his grip further, pushing harder; she knew he was close. Raising his head, he let out a deep groan, and on his next push she felt it begin, his cock shifting powerfully inside her snug grip. She could feel it filling up inside her. He kept thrusting, and she could feel his cum starting to slide down from her slit as he pulled back, then squish out in splatters against her inner thighs as he plowed in again. His moan weakened, losing breath and falling from animal to something much more human, more like the boy she knew. He thrust in one last time and held it, his cock continuing to throb forcefully, every jump and pulse clearly felt inside her. His body tensed and writhed on her, his strength vanishing in her arms, and she hugged him tighter. Pushing off the bed, he rose from her as best he could. His hips fell back and his cock slid out of her. A flood of cum ran from her pussy and down her butt crack onto the bed. He held himself over her, hovering, dimly returning to his senses but unable to move himself further. His dick remained hard and hung over her between her belly button and her pussy, still pumping. His cum flowed out like a faucet, greater pulses coming out when his dick twitched, but always pouring at a steady pace. His body continued twitching over her, the oncoming cords of cum lashing across her, draping and folding back on themselves all across her hips, stomach and most of all her pubic hair until it was covered in a mess of crossing lines and globs, much running down along the creases of the edge of her thighs and across the front of her pussy itself. It was no wonder he turned crazed on these nights, Betty thought, with all that semen inside him demanding to come out. She had her hands on his sides, holding him up and steadying him, watching the stream taper down and the motion of his penis lessen until they stopped entirely. As she held him up, his own arms started giving way. His eyes closed and body almost still, he was back to simply being her brother again, sweet and exhausted. She helped him collapse onto the bed beside her. He panted slowly, completely spent, his cock finally receding. He looked ready to sleep immediately, and she knew that he would soon drop off into a deep sleep for the rest of the night. With it finished, she lay back into her bed, taking stock of the event. There had been much less initial discomfort this time; that was good. After a good night's sleep, there would be few lingering effects, besides the typical bit of soreness the next day. All in all, it had gone better this time than she had hoped for. With her brother fallen asleep beside her, everything in the room was suddenly still, calm. She heard distant voices outside in the apartment complex, adults talking and laughing mixed in with a few excited squeals from children who were still out. She looked down at herself in the lamp light, glad it hadn't been broken in the action, as had happened two years before. Her breasts were still moist with his saliva, her stomach muscles sore from their sudden heavy use. Beyond, her forest of dark, curly hair remained drenched in thick, sticky fluid. Some areas kept a clear lined structure layered across the top of the hair, while in other parts, the semen had oozed together and sunken through the hair to the skin. She stayed relaxed where she lay. There was no rush, after all, and there would be plenty of time to clean up later. For now, she was tired herself. She could still feel some cum oozing and dripping out of her vagina, adding bits to the puddle beneath her. She reached down and touched lightly around some of the more tender parts on her engorged vulva. There was too much semen to simply wipe away, and she decided the coating of his still warm cum felt something like a balm on her used flesh. She spread a glob near her thigh up to a particularly sensitive spot on one of her labia, and then smoothed another glob around on top of her clit, soothing it. She arched off the bed slowly, stretching out her hips this way and that. She slowly laid back into her pillow again, relaxing; leaving her hips spread wide and her crotch drenched. The sizable pool of cum beneath her had slid when she arched up, rolling into the spot that had been slightly compressed by her bottom, so that when she came back down, she came into it. There was nowhere else on the bed to go with her brother there, and too much cum to avoid, even if she wasn't too tired to bother. She slowly eased her tensed butt muscles and let them lower into it, accepting it as it surrounded her, squishing upward from her weight around and even between her butt cheeks. Casually, she pushed the globby pool away a bit from between her legs, feeling it slide back against her, up between her thighs to the very edge of her pussy. She wondered if she really could handle this more than once a year, or if once a month would just be too much. The experience was always so intense, for both of them. Either way, it had happened like it had. Sometimes it was best to let things alone. Her head drooped to one side as her mind as she let herself became aware of the rest of the world again, taking stock of the room around her. With a slump, she sighed and cursed herself slightly. She'd left the book sitting right out on the nightstand. Careless, and very sloppy. Her brother stirred beside her, and she froze a second with a shot of witless fear. Not opening his eyes, he shifted a last time and settled back in. She relaxed. In no time he'd be dead asleep, she knew, oblivious to the world until morning. Carefully, so as not to shift the bed or disturb him, she reached down to a knob on her nightstand and pulled off a large, torn patch of the shirt she'd been wearing from where it had caught as it fell. She stretched it out and draped it over the book to cover it. Later on, after he was solidly asleep, she could hide it away again before she started cleaning up. It was unlikely that he'd have noticed it, or had any idea what it was if he had, but there was no point taking any chances with the small spellbook. Someday, she would explain it all to him; let him know what really caused his transformations. She had never planned to deceive him, always wanted to explain it to him. She just had to wait until the time was right, until he would understand. Perhaps she should have told him already, told him right at the start. That first time, though, she hadn't really expected it to work, and was taken so off-guard by the spell's effectiveness that she would have chickened out if it hadn't already been too late. But since then she had strung him along, let him believe he was somehow guilty of something, and that was cruel of her. But once she'd tried it, it was simply too good to give up. In the last fifteen minutes, she'd had three of the most intense orgasms she'd ever had. Or maybe just three peaks in one long orgasm, she wasn't even sure. She wasn't just going to give something like that up. And, after all, she'd always tried as best she could to make him see it was a gift and not a curse. And this time, just maybe he was starting to come around. It was different this time from the moment he'd walked in her door. She had seen it in him, the way he looked at her just in the corner of his eye. At least part of him wanted it. It wasn't just guilt and fear this time. Even before the spell was on him, some bit of him was looking forward to fucking his sister. That must have been why he'd acted so differently this time. He wasn't completely fighting it anymore. Yes, she'd tell him. Not yet, but soon. He was almost ready. Just a little more coaxing and he'd come around. One more year should do it. Twelve months she could spend nudging him in the right direction, and then she'd explain it everything. After he'd fucked her one more time. And if she could just get him on board, well, the sky was the limit. Maybe once a month wasn't so outlandish after all. She was really getting the hang of it on her end, after all. And the more they did it, the easier it would get. She was almost out of college; she could move close to him and they could cast their spell once a month, or even once a week. They wouldn't have to hold to some arbitrary schedule anymore. They could do it whenever they wanted. She turned her head and looked at her brother, exhausted into unconsciousness. He was on his side, his dick hanging limply to the bed, a wet spot developed just beneath it. She let her hand drift to it, lightly petting it in its new, much less imposing state. She might even be convinced to try some things without a spell on. She'd convince him, she was sure. She was his sister. He loved her and she loved him, no matter what. He'd have to see the beauty of it. He'd be pissed at first for what she'd done, certainly. But that deep, primal part of him, that thing which the spell couldn't create but only call forth, that piece that craved her pussy with a passion and soaked her body in his cum would win out it the end. And then it would just be her, her little brother, her spellbook, and her bed. It was only a matter of time. She kissed him gently on his cheek, then laid her head next to his and closed her eyes.
