Saturday Evening
Madelyn remained face down on the mattress, scrunching herself up in an attempt to remove her skirt and panties, the latter of which were soaked and peeled away from her quim quite reluctantly. She then quickly yanked her blouse off, ripping away several buttons in the process, and raised her head just long enough to pull her still-fastened bra over it, fighting briefly when it entangled with her dark tresses. Finally naked except for her ankle socks, which she tried distractedly to remove with her toes, she put her face in her pillow and raised her ass high in the air, fingers seeking out her steamy depths.
Unbidden, her mind conjured images of her sister taking naked selfies in the bathroom mirror, then posting them online. Then her sister was standing in a studio, posing for nude photographs. Her poses got progressively more risquΓ© as the fantasy continued, until finally her sister was spreading her legs wide and holding her lower lips apart, exposing her glistening petals to the world. Then the fantasy Allison mimicked her sister, with her head down and ass up, holding her cheeks wide to expose both her holes. Madelyn groaned with lust, forcing another finger and then a third into herself, heedless of the drips of her lust she sent flying.
Fantasy Allison was now being fucked from behind by some faceless man with a porn-star dick, her eyes empty and staring at the camera with mindless obedience. Then she had two men fucking her, then two women, and finally some indeterminate number of bodies surrounding her, groping her, penetrating her. The image that finally pushed Madelyn over the edge, though, was her sister using the remote on Maddie to force her to join the gang bang. Her screams muffled by her pillow, Madelyn's pussy contracted hard enough to force her fingers out, along with a stream of juices. Several smaller jets followed the first as Madelyn slowly slumped until she was lying flat on her bed, semi-conscious and blissful.
The bliss was short-lived. A few minutes later the sound of the shower ended and Madelyn suddenly realized what she had done. Horrified, she rolled over and looked at the evidence of her shameful lust in the large, wet stain on the comforter, not to mention her ruined blouse, which had also been blasted by her squirt. Picking up the soiled garment, she tried for a moment to use it to clean her hand and the blanket, to little avail. Giving it up as fruitless, she hugged her knees to her chest and started rocking back and forth.
She wasn't ready to believe that the remote was actually magic, because that was ridiculous, and anyway it raised more questions than it answered. So if the remote wasn't responsible, where did that leave her? Had she inadvertently discovered a kink she didn't know she had? Madelyn wasn't exactly innocent, but she certainly didn't consider herself to be kinky. Yes, she and her last boyfriend had done a little roleplay and dress-up a few times, but nothing too unusual. And Maddie had experimented once with a girl at a Halloween party her freshman year, which her mom might consider kinky but was really quite commonplace these days, she felt. But she had definitely never, ever had any such thoughts about her sister.
Madelyn's gut gave another squirm of guilt at the reminder. And truthfully, forcing herself to think of Allie emerging naked from the shower, toweling off, even playing with herself wasn't currently getting a rise out of Madelyn. Was it just because of her recent orgasm? Was she just not in the mood anymore? Or was it the mind control aspect that piqued her? Imagining her sister with that blank stare as she was rammed from behind made Madelyn's nipples twinge and her pussy clench.
"Well, that cinches it," Madelyn murmured to herself. "I apparently have a mind control fetish." Staring doubtfully at the remote, which had landed off to the side of her bed, Madelyn picked it up gingerly and examined it. Was it just a fantastic coincidence that it was supposedly able to control or change people that awakened her unknown fetish? After all, there was no proof whatsoever that it had done anything to her sister. Yes, it apparently knew if there was a target or not, which suggested an unusual degree of sophistication for such a simple-looking device, but that might also be coincidence since Madelyn had only tried to use it twice.
Deciding that another experiment was in order, Madelyn pointed the device at the wall her room shared with the bathroom and hit the green button, which once again caused the screen to display 'TARGET ACQUIRED.' Pushing the red button, however, caused the screen to flash 'ERROR,' followed by 'TARGET ON COOLDOWN' and a timer counting down from just under 48 hours. Then the screen flashed 'ERROR' again, this time followed by the message 'POWER TOO LOW' and a battery shape with 28% inside, which ticked up to 29% as Madelyn was watching.
Frowning, Madelyn examined the device more carefully, looking for any evidence of a power cord or port, battery case, solar panel, or anything else that would explain how it was powered and how it was apparently regaining power. But other than the buttons, screen, and antenna, the device appeared to be a single, solid piece of material, with no sign of a seam or even screws or other fasteners. Baffled, she turned the antenna on herself and pressed the buttons, but got the same error messages, except that the cooldown timer for her was just under 43 hours. Did that mean it had already been used on her? Did her mother, finding it in a box, accidentally trigger it, perhaps giving her daughter a mind control fetish?
Loath as she was to believe the remote actually worked, Madelyn did feel a slight bit of hope that her shameful, incestuous masturbatory fantasy had ultimately been fueled by external forces and not her own hidden depravity. But just thinking that she had been mind-controlled to fetishize mind control was enough to get Madelyn aroused again, and she found herself biting her lip and reaching for her pussy. But the sound of the front door opening and closing, and her mother calling, "Girls! Dinner is here!" caused her to jerk her hand away and scramble around the room looking for something to wear.

Allison stepped out of the shower and started drying herself, humming tunelessly. She was feeling distracted and restless, and she wasn't sure why. It was kind of like the feeling she got when she forgot an assignment was due, but somehow still remembered that she had something she needed to turn in. But clearly that wasn't the case, as it was summer vacation and she had no classes and all her paperwork to join her sister at her college next fall was completed months ago.
Wrapping her dark brown hair in a towel, she stood naked in front of the bathroom mirror and started putting lotion on. For some reason, tonight she paid extra attention to the way her hands moved over her body, leaving trails of shiny, glistening skin behind them. Her hands slowed, their movements becoming more like caresses. They gradually moved up until she was hefting her modest but perky breasts, as if presenting them to an audience. Gazing at her nipples she gave them a tweak to make them stand proud. She was usually slightly embarrassed by her nipples, as they seemed oddly large compared to her breasts, standing out almost an inch when she was aroused. But tonight they seemed extra attractive, because Allison knew not many other girls had such prominent 'high beams.'
