In the Dressing Room

There is no real reference to any plots in the TV series except for the duplication spell that they learn in one of the early episodes. This is independent from my first WoWP story.
******************************************************
PART 1: A MOMENT OF WEAKNESS
Justin had tried to be good. He dated girls his own age. But it was hard to think about other girls with Alex as his sister. It seemed to Justin that she was getting more irresistible every day. He made excuses to go into her room when he thought she might be changing. He had gotten a few precious glimpses before Alex started remembering to lock her door.
Of course, being a wizard, Justin knew that there were magical ways to get what he wanted. In a moment of weakness he had even snuck into the lair and browsed his father’s forbidden spellbooks. None of the Russo kids were supposed to see those spells until Jerry deemed that they were mature enough not to abuse them. In one of those books Justin found a spell that he could use to take advantage of his sister. Unfortunately, Justin came to realize, his own conscience would not let him use the spell. Justin did love his sister, after all. That he also lusted for her didn’t change the fact that he didn’t want her to be hurt. So the spell remained in the back of his mind, torturing Justin with promises of pleasure.
******************************************************
It was late afternoon on a Friday. Justin was reclining in his living room and zoning out in front of the TV after a hard week of school. Just when Justin was on the verge of falling asleep Alex raced down the spiral staircase from upstairs. Unable to resist, Justin took a moment to appreciate his sister’s outfit. Alex was wearing tight blue jeans which defined her butt perfectly. Today she was wearing a loose and fairly low-cut white shirt. Completing her outfit was a gray vest worn over her shirt which was much too small to serve any practical purpose.
“Hey, Justin, can I see your credit card?” Alex dropped onto the couch and smiled at him. Last week Justin had gotten his first credit card after spending months convincing his dad to cosign it. Almost before he had opened the envelope, Alex had been begging him to loan it to her.
“Alex, for the last time, I’m not going to let you run around the mall with my only credit card.” This would typically be followed by several minutes of Alex asking over and over, with no result, until she stormed off. But today she had another strategy.
“Well, then, come with me. Harper’s got the flu anyway; I need someone to tell me how great I look when I try on clothes.”
Justin rolled his eyes. “Gee, Alex, as much fun as that sounds, I think I’ll pass.”
Alex seemed to be struggling with some inner debate. “I don’t have any money now but, if you buy the clothes for me, I’ll pay interest when I do get the money.”
Justin was surprised, but not swayed. It was unlike Alex to offer to pay him back extra. She must really want the thrill of using a credit card, Justin thought.
Seeing that he wasn’t moved, Alex switched to the sweet-little-sister approach. “Come on, Justin. Pleeeease.”
Alex gave Justin her sweetest look, complete with pouting lips, moving closer to make sure that he didn’t miss it. Justin glanced over. Damn it, her bottom lip is quivering! Then his eyes fell a little lower. When Alex had leaned toward him, her shirt hung low enough to give Justin a nice view of her breasts. Between Alex’s cute face and her cleavage, it was a forgone conclusion. He looked up quickly, hoping that Alex didn’t notice anything. His eyes flicked down to her chest one more time and he gave in.
“Fine, Alex. Go put your shoes on.”
Alex looked like she was on the verge of questioning his change of heart but she stopped herself. Jumping up off the couch, she ran upstairs. Sighing, Justin got up out of his chair and went to get his own shoes.
PART 2: IT REALLY WASN’T FAIR
Justin trudged after Alex through store after store. It was one thing to agree to go with her during a moment of weakness, but it was another to actually do it. Alex seemed to remember that she would have to pay Justin back, with interest, because she mostly just browsed in the stores. After over an hour, Justin had only made one small purchase for his sister but she seemed determined to investigate every clothing store in the mall. Justin had thought that it might be fun seeing his sister in a lot of different outfits, but, when she did decide to try something on, it was almost always a modest and layered outfit.
Justin followed Alex into a store that he didn’t even bother to check the name of. He got his hopes up when she took him through the swimwear section, but Alex didn’t even pause. When they reached the back wall of the store she began sifting through racks and shelves using a method that Justin couldn’t begin to understand. A little while later Alex had loaded Justin up with what he was pretty sure was every article of clothing in the teen section.
Alex gestured dismissively to Justin. “Take that stuff to the changing rooms; I’ll be there in a minute.”
Justin gave Alex a hard look to let her know that she was pushing her luck. She, of course, pretended not to notice. When Justin was gone, Alex went back to a shelf of skirts that she had seen earlier. They were probably half the length required by her high school’s dress code. They were pink, frilly, and the kind of thing that Alex would never be caught dead wearing. Still, Alex decided to try one on. She thought it would be fun to shock Justin when she came out of the changing room.
“What’d you find?” Justin asked when Alex sauntered into the changing room waiting area. He was the only person there and he was relieved to be in the secluded area where there was less chance of anyone he knew spotting him.
“Just one more thing,” she answered, holding up a crumpled wad of fabric. “Where’d you put my stuff?”
Justin pointed. “It’s in the handicapped stall. That was the only one big enough to hold all the clothes.”
“Ha. Ha.” Alex sneered at her big brother as she walked over and closed the stall door behind her.
Maybe this will wipe the smirk off his face, Alex thought evilly. She pulled off her jeans and slipped the miniskirt on. Alex grinned. It was very slutty and, unlike some of the skirts that she owned, there was no strip of fabric in the middle to hide her panties from an accidental upskirt view. That would be fine. After all, she just wanted to stun Justin not actually buy the thing. Now all that she needed was a slutty top to go with it. Alex rummaged through the pile of clothes sitting on the bench. Eventually she found a pale yellow V-neck shirt. She shrugged out of her white top and pulled on the new shirt. It was intended to be worn with another shirt underneath it to cover more skin but Alex thought it would be perfect since it revealed a lot of cleavage. Then she noticed that a little bit of her bra was visible. After a moment of indecision, Alex unclasped her bra and maneuvered it out from under the shirt. She decided that this would be fine since the shirt still covered her nipples. Alex was feeling a little self-conscious now, but she was determined to shock Justin.
“Hey, Justin, I’m ready.” Alex ignored Justin’s half-hearted reply and pulled the door open. “What do you think?” Justin was standing right outside the door when Alex opened it. She batted her eyes at him, pretending to flirt. Justin’s mouth made a little motion that might have been a gulp and his face had some emotions that Alex couldn’t quite interpret. Determined to play the part of a girly-girl, Alex gave a little twirl.
Justin’s senses went into overload. He was close enough that the breeze her skirt created danced across his bare arms and sent up a tingling feeling. His eyes followed the curves of her body as she turned. He knew, even if he couldn’t see from this angle, that her panties were in full view as her skirt flew up. When Alex completed her spin the loose V-neck had slipped slightly and one of her small breasts had spilled out over the edge. Justin wanted to die in that perfect moment. It wasn’t fair.
Just as Alex noticed her shirt’s slippage, Justin lost his last shred of self-control. Before she could say anything, Justin blurted out, “Surdus.” It wasn’t the forbidden spell; all it did was stifle a person’s vocal chords so that they couldn’t speak. This wouldn’t be a big deal for most people but for wizards it means that they can’t cast spells. Panicking a little, Justin pushed Alex back into the stall. She reeled back in confusion, her arms flailing as she tried to keep her balance. She tripped over a loose piece of clothing and fell to the floor. She tried to shout to shout but no sound came out.
Justin’s quickly brought another spell to mind. This one was much more complicated and no one knew that he had the skill to cast it. He had perfected it to distract himself during the long nights when he couldn’t sleep, thinking about Alex just a few doors down the hall. And maybe, just maybe, he had imagined that he could one day use it against Alex. The spell manipulated spatial and temporal aspects of reality. In essence, Justin was knotting the stream of time within the changing room stall. As he cast the spell, made more difficult due to the fact that he had to keep forcing Alex down to the floor, a few seconds of time were looped within the stall. Completing the spell, Justin sank to the floor. It was one of the few pieces of wizardry that was physically exhausting but now, no matter how long they were in the stall, only a few seconds of time would pass by outside. The nature of the enchantment meant that it would be impossible to leave the stall (since it was now on its own timeline) without first dissolving the spell.
Alex had gotten up and was screaming at Justin; at least Justin assumed that she was screaming. With the spell of silence still in effect there was no way to know if she was simply making faces at him. Justin decided that she was probably screaming because she began to kick him, too.
Summoning his strength, Justin got up and forced Alex back to the floor. He straddled her and ripped her shirt off at the seams. The thin fabric tore easily and Justin was momentarily distracted by Alex’s bare breasts. Alex seized that opportunity to shove Justin off of her and struggle to her feet. Justin reached out to pull her back down but only managed to pull the miniskirt down her long legs. She kicked it off and, wearing nothing but white panties, Alex tried to pry the stall door open. It was useless, though, since Justin’s spell had sealed the room. Justin stood up and moved behind Alex. He roughly pulled her panties down to her ankles. Alex tried to turn and push him away but her panties caused her to trip and fall to the ground. Justin quickly reached down and pulled the panties all the way off.
PART 3: X MARKS THE SPOT
Considering how small the changing room was, it was surprisingly difficult for Justin to hold Alex down. Justin was getting tired of the struggling. He could try the forbidden spell, but he wanted to keep it in reserve. Justin let Alex crawl away. She curled up in a corner of the stall and tried to cover herself with extra clothes. Ignoring her for a moment, Justin reached out and cast a spell on the tile floor of the room. “Liga puellus.”
As Justin bent down and touched the tiles, they seemed to shift and become liquid. A ripple spread outwards toward Alex, who realized too late that she should have climbed onto the bench. She actually managed to stand and get one foot on the bench, but the tile was already gripping her other leg. The fluid tile flowed up Alex’s pale skin until she was encased from the shoulders down in a ceramic suit. Under Justin’s magical instructions, the tile pulled Alex down and forced her to lay flat on her back on the floor. It then seeped off of her and pooled around her wrists and ankles. Once Alex’s arms and legs were spread in an X, the tile hardened to prevent her from moving.
Naked and helpless, Alex glared up at her big brother. Justin was breathing heavily, and not just from their recent strip wrestling. There was finally nothing stopping him from taking his little sister’s virginity. Savoring every moment, Justin peeled off his own clothes and his eyes never left Alex. Any lingering hope that this was all some kind of prank vanished from Alex’s eyes. She started thrashing and cut her wrists and ankles against the tile holding her in place.
In retrospect, Alex’s struggling probably wasn’t a good idea. If there was one thing that was guaranteed to stoke Justin’s lust it was the sight of his naked little sister bucking her hips as she tried, and failed, to free herself. Justin slowly knelt down and straddled one leg on either side of Alex’s stomach. He brushed away a few tears that were rolling down her face. Alex tried to bite him.
“Come on, Alex,” Justin pleaded, suddenly guilt-stricken. “You’re the one who…dressed like that. This isn’t my fault.” Justin paused, half-expecting to see Alex’s characteristic eye rolling. But she just glared at him and mouthed something, fresh tears already falling down her face.
Hesitantly, Justin ran his hands along his sister’s body. She squirmed under his touch but couldn’t get away. He kneaded her breasts and rolled her nipples between his fingertips. Alex bit her lip as Justin’s hands followed the curves of her body down to a spot that was, against all her wishes, beginning to tingle with anticipation. Justin shifted his body down towards Alex’s legs, his cock already standing at attention. Absurdly mumbling an apology, Justin pushed his cock into his sister. Alex gasped and begged soundlessly for him to stop. He pulled out quickly and, briefly, hesitated. But it would have been next to impossible to stop now. He carefully realigned himself and thrust back into Alex’s pussy. Caught up in the excitement of long-denied desires, Justin started moving faster. He ignored a momentary resistance, ignored the blood that began to mix with Alex’s juices. All that mattered was that he and Alex were together at last.
PART 4: SEEING DOUBLE
Minutes, hours, or days later Justin had fallen asleep. He woke up right next to Alex who seemed to be sleeping. Justin watched at Alex lovingly; she always looked so innocent when she was asleep. On some level Justin was sorry for what he had done but at the same time he knew that he hadn’t sated all of his lust yet.
It would be so much better, Justin thought, if Alex could just enjoy this. Justin’s mind was drawn back to the magical way to make her to lust for him: the forbidden spell.
Coming to a decision, Justin muttered, “Cupiditas.” A small ball of pale light congealed in Justin’s outstretched hand. It drifted from his fingertips to settle between Alex’s breasts. The light spread out across her limp body and sank beneath her skin. For the briefest of moments Alex’s body seemed to glow from within, lending her beauty an unearthly quality. The light quickly faded and nothing seemed different. Then, Alex suddenly gasped and her eyes flew open. Justin leaned closer. Alex’s eyes had dilated and she was staring vacantly at the ceiling. She turned her head and met Justin’s questioning look. Alex smiled at him and licked her lips seductively. She began straining against her bonds again but, this time, she was trying to move closer to him. Justin cast a spell to let Alex speak and another to dissolve the tile bonds. Alex all but jumped on top of him.
She pressed Justin down to the floor and dug her nails into his shoulders. Grinding her hips against him, Alex whispered into his ear, “What did you do to me? I can’t…stop…wanting you.”
Secure in his magic, Justin whispered back, “Do you want to stop?”
There was a slight hesitation as if Alex was trying to resist the spell’s influence. Then, she murmured, “No.”
Urgently, Alex guided Justin’s cock to her folds. She groaned as she pressed against him and forced him into her. Justin tried to pull Alex down into a kiss but she wouldn’t, or couldn’t, stop herself for even a moment. Their excitement built together as each sibling responded to the other instinctively. Their pleasure climbed, steadied, only to climb further. Minutes passed until the thrill became unbearable and they came together. Alex practically fell off of Justin and curled up next to him, panting as he was, trying to regain her breath.
Alex groaned again. She was completely in the thrall of the cupiditas spell. The more they did this, the more she would want it. Eventually, unless the spell was broken, it erode Alex’s mind until Justin was the only thing she could think about.
After her heart rate had settled somewhat, Alex stood up. A delighted smile spread across her face as an idea came to her. She concentrated and muttered, “Edgebono utoosis.”
Another Alex seemed to stretch out from the first. Justin was now staring up at two beautiful naked girls and, better yet, both of them were Alex. Because Alex was under Justin’s cupiditas spell when she duplicated herself, her clone was just as infatuated with Justin as she was.
Justin slowly got up. “Wow… umm nice work, Alex.”
“Thanks,” The girls answered together.
“You actually got the spell right,” Justin noticed, “your clone can talk and move on its own.”
One of the naked girls stepped closer. “That’s not all I can do,” she smiled and brushed her fingertips across Justin’s bare chest. The clone guided Justin to the bench and sat him down. Smiling, she kneeled on the floor in front of him and brought her lips to his hardening cock. The clone took it into her mouth. Justin was once again finding it hard to breathe normally. He cringed forward as the clone began circling his cock with her tongue. The real Alex watched them for a few moments before walking over and straddling her legs on either side of her clone’s kneeling body. While the clone continued to tease him with her tongue, Alex leaned forward to kiss Justin. She grabbed his head with both hands and ran her fingers through his hair. Their kiss deepened and Alex forced her tongue into Justin’s mouth. Justin wasn’t doing a very good job of kissing back; he kept losing his concentration as the clone took his cock deeper into her mouth. Justin broke off the kiss abruptly and bit his lip, hard, as he came into the clone’s mouth. The clone struggled with it for a moment before swallowing. Justin barely had time to recover his breath before both girls converged on him again; the cupiditas spell drawing them back to him.
PART 5: AMNESIA ANYONE?
Justin was getting very hungry. As near as he could estimate, he had spent at least a full day, maybe two, in the changing room with Alex and her double.
I could, Justin thought, make food appear magically. But Justin knew that if he started doing that it would be a long time before he found the willpower to return to the normal world. After all, with magic serving as the ultimate Viagra and also the ultimate contraceptive, he could literally go on forever. With a sigh of regret, Justin cast a spell to merge the two girls back into one. Alex struggled to stand up and go to him, still caught up in his spell of lust.
“Alex,” Justin began, “I need you to get dressed in the clothes that you were wearing when we came into the store.”
Alex walked over and pressed herself against him, which did nothing to help Justin’s self-control. “You’re going to stop this, aren’t you?” Alex hugged Justin tight. “I don’t want to stop.”
Justin tried to ignore his sister’s breasts pushing against his chest. He failed of course, but at least he tried. In an effort that could be called superhuman, Justin disentangled himself from Alex.
“Please, Alex, I promise that we’ll always…always be together but you have to put your clothes on now.” Alex looked up into Justin’s eyes. She couldn’t see the lie, even though it was breaking Justin’s heart. As soon as Alex was dressed Justin cast a spell on her that sent her to sleep. He caught her as she fell and removed the cupiditas spell. Two more spells blocked out Alex’s memories and numbed any soreness she was feeling. Justin positioned his sister so that she was sitting on the bench in the changing room and then dissolved the spell that was looping time within the room. He left the stall and cast a final spell to wake Alex up.
Inside the stall, Alex opened her eyes and shook herself. She wrinkled her nose at the strange smells that, to her, seemed to suddenly fill the room.
“Are you all right in there?” Justin asked from behind the door.
“Yeah,” Alex called. She rubbed her stomach. “God, I’m hungry. I know we ate before coming here but I’m starving.” She opened the door, surprised that she hadn’t locked it while she was changing.
“All right, let’s hit the food court. Were there any clothes that you wanted to buy?”
“Hmm…” Alex looked back at the pile of clothes with no memory of having tried any of them on but not wanting to admit that. Strangely, some of the clothes looked like they had stains of blood and maybe other liquids on them. Alex shook her head in confusion and picked out one of the few pristine pieces in the pile. “Maybe just this.”
Alex held up the miniskirt that had started it all. She smiled up at her big brother and reached out to touch his arm. “I’ll…try it on for you later.”
Suddenly shy, Alex turned and started walking toward the register. Justin smiled as he pulled out his wallet. So what if he hadn’t removed all traces of the cupiditas spell? A little bit of lust for him wasn’t going to kill Alex. It was subtle enough that no one would find it and, who knows, maybe it would grow on its own. Or, Justin thought, I could always give her another little push.
