Katie grinned as the light from the sunrise peeked through the windows. It was finally done. Her Cognitive Override Device (or CORD for short). Months in the making, this was the invention that was going to put her on the map, she just knew it. The CORD used a combination of short range Delta and Theta waves to bypass conscious thought, implanting ideas directly into the subconscious of people close enough.

“Katie! Its almost time for school! Hurry up and get breakfast” Her mom yelled up the stairs.

Katie stretched, trying to work out some of the stiffness in her back. One of the downsides of being as busty as she was is the lower back pain. She was envious of her little sister at times, her more petite and athletic body not causing any issues like this. She stood up and began going through her drawers, putting on t-shirt with a hoodie over it to alleviate the staring she got from the boys in her classes, and a pair of ripped jeans. She quickly ran a comb through her bright red hair, before putting it into a quick ponytail. “Coming mom!” Looking at the CORD, she made a spur of the moment decision and grabbed it, her mind drifting to the main thing she dreaded about going to school.

Robbie had been bullying her for years now, ever since she convinced her friend Jenn to break up with him. The trauma he had inflicted on her…stolen lunch money, name calling, the physical **** from wedgies…she’d been nearly put into in-patient care for depression before she discovered her love for science and thrown herself into it. Now, she enroute to an elite college with a STEM scholarship where she could put that asshole behind her forever. Except, part of her, a large part if she was honest, wanted **** for all the ordeal he’d put her through before she moved on completely. Looking at the CORD in her hands she muttered to herself. “I deserve some justice too…” she trailed off.

“What was that sis?” Katie looked up to see her older sister Lily standing in the doorway. “You just missed the bus, so mom is making me drive you and twins to school now. So, move your ass, because I don’t want to be late for college.” Lily was built very similar to Katie, except probably a little curvier. Unlike Katie, she wasn’t as shy about it. The older girl was big into goth culture and was currently wearing a blood red tank top with black long sleeve fishnet top underneath. Her black bra peaked out teasingly every time she moved. Her hair was dyed a deep black and she had matching lipstick on.

Katie hastily shoved the CORD into the pocket of her hoodie, blushing as she did so. “N-nothing Lily.” She followed her sister downstairs, giving a fake “gagging” noise when she saw her mom and dad in a loving embrace in the kitchen.

“Hey now, none of that.” Her mom said while lovingly tousling her hair. “Here, I packed you extra snacks, I know how hungry you can get.” Her mom handed her a large lunch bag

“Thanks mom.” She gave her mom and dad a quick kiss on the cheek and grabbed a muffin for breakfast, running out the door. Already out by Lily’s care, arguing about lord knows what were her younger siblings, Hannah and Mike. Despite being younger than Katie, they were in the same grade as her, a testament to her parents’ feelings for each other, as they were only 9 months younger than her. Both of them were smaller and more lithe, lacking the curves of their older sisters, but having more athletic forms. Both were stars on the track team and were looking to lock in track scholarships for college in the next few months.

Arriving at school, Katie rushed to her locker, anxiously. If she was going to get her ****, she needed a plan. Nervously, she fingered the device, lost in thought. Suddenly a voice called out, and she was shoved into her locker.

“Hey bitch! You’re blocking the hallway!” Robbie laughed as he pushed her, laughing as she stumbled headfirst into the wall of lockers.

“H-hey asshole…why don’t you…f-fuck off!” Katie stammered, trying to stand up taller, rubbing the bump forming on her forehead. She was nervous, more so because she hadn’t had time to make a plan and she was exhausted from being up all night, but it was now or never. As she spoke, the hallway grew deathly quiet, the other students all stunned by Katie standing up Robbie. A small crowd was gathering to watch the conflict.

His face immediately changed demeanor, his shit eating grin falling away to reveal a look of stunned anger. “What the fuck did you just say to me, freckle-face?”

Katie pulled the CORD out of her hoodie and held it up, gaining confidence as she talked. “I don’t n-need to listen to your shit anymore. This thing puts me in charge.” She moved the CORD device to her throat and spoke. “Robbie, sing the teapot song.”

“I’m a little teapot short and stout…!” Robbie began singing the teapot song, acting out the motions. As he finished up, he turned back to her. “Now, I’m gonna make you pay for mouthing off to me, bitch.”

“No, Robbie. Drop your pants.” Katie giggled as Robbie dropped his pants around his ankles, standing there in boxers. He began to slowly waddle towards her. Katie raised the CORD to her throat again, preparing to stop him, when the bell signaling class was beginning rang.

“Oh no! I’m gonna be late for class!” The freshman burst out of the girl’s bathroom and ran right into Katie, knocking them both on to the ground. The CORD went sliding across the floor, stopping at Robbie’s feet. Her stomach dropped as he began to reach down and picked it up, and she began scrabbling on all fours to get to him, to stop him from realizing what he had. “Robbie…no!” There was a faint buzzing and she looked around on the ground. She couldn’t see the CORD, but Robbie didn’t have it. It must be on the ground somewhere. She frantically looked for it, her stomach doing flips.

“What is going on here!” Called out a loud, feminine voice. Ms. Kirkland stepped out of her classroom, a frown on her young, pretty face. Ms. Kirkland was the teacher all the boys had a crush on. She was recently out of college and was drop dead gorgeous, large breasts and an ass to match. Her striking blue eyes scanned the crowd before settling on Robbie. “Robbie…I should have known you’d be the one causing problems. Go to the principal’s office and pull your pants up!” She walked over and helped Katie to her feet. “Did he hit you, Katie?”

“What…? No, no he didn’t. Someone ran into me.” Katie was still frantically looking around the ground, trying to find the CORD, but to no avail. She glanced at Robbie again.

Robbie was looking at his hands for some reason she couldn’t fathom. “Yea…the principals office.” He grinned broadly. “I think I will. Katie…I’ll see you later.” He turned and walked away, chuckling to himself.

Katie took a deep breath, trying to calm herself. At least she knew Robbie didn’t have it. Someone else must have picked it up. She’d have to be alert to signs of it being used or ask around and see if they would give it back. She sighed again, trying hard to calm her nerves.

Robbie saw Katie standing at her locker, staring into the distance. Perfect, he could teach that uppity bitch a lesson. He casually walked up to her and shoved her from behind, causing her to stumble into her locker. Adopting a faux-annoyed expression, he loudly said ““Hey bitch! You’re blocking the hallway!” He couldn’t hold back his laugh as he saw her head bounce off the locker.

Then, something happened that he couldn’t believe. The little bitch stood up and mouthed off to him. “H-hey asshole…why don’t you…f-fuck off!”

“What the fuck did you just say to me, freckle-face?” He growled out. He was gonna teach this bitch a real lesson today.

That’s when she pulled out a strange looking device and said something about it putting her in charge. He was still trying to figure out what she meant when he felt the need to sing the teapot song.

Yea…that’ll teach this bitch. He put his arms in position and began belting out the song. Once he finished, he grinned, ready to pound this stupid whore. But first, he needed to drop his pants. That’s when the bell rang and that freshman ran into Katie. Her little device slid across the floor and stopped at his feet. Reaching down he picked it up and examined it. Katie screamed and began to crawl towards him. Bringing the device to his throat like he’d seen her do, he spoke. “I don’t have your device.”

The effect was instantaneous. She immediately looked away from the thing in his hands and began frantically looking around on the ground for something. Understanding instantly dawned on him. This thing could control minds. Holy shit…this thing could control minds!

Hell, he didn’t even care when Ms. Kirkland made him go to the principal’s office, although he regretted not using this on her tight little ass. Still…plenty of time for that. For now, well, he had a visit with Mrs. Harris.

Robbie whistled as he walked down the hallway, a spring in his step as he entered the principal's office, walking right up to the school secretary, a pretty and fit young blond woman, around 25 years old if he had to guess. “Hey Liv, you’re looking hot today.”

She visibly shuddered as he openly hit on her. “Robbie, it’s Ms. White, and you’ve been spoken to before about your attitude and choice of words. You can be sure I’ll be writing this up for Principal Harris, and I’ll be pushing for you to get expelled.”

“You and I always do risqué flirting when I visit the office. I’m sorry you feel that way, sexy.” Robbie couldn’t keep the wide smile from his face.

Kris shook her head, looking confused, before she got a naughty grin on her face. “Oh, yea stud, sorry about that. I guess I got a little flustered by how hot you make me whenever you walk into the office and forgot who I was talking to.”

“No worries slut. Now, when are you gonna let me take you out to dinner and then let you give me a hot blowjob in the back of your car?”

Liv giggled. “I bet you’d love that, wouldn’t you Robbie.” Liv purred. “Raunchy flirting is one thing, but you know I have a fiancé.”

“The idea of cheating on your fiancé with me is hot. Cucking him with me is one of your secret fantasies. Well, can’t blame a guy for trying to get with a hot piece of ass like yourself, can you.”

Liv gasped, blushing slightly. “Actually…I’m supposed to see him Friday night. Maybe you and I should meet up earlier in the afternoon. Wouldn’t it be hot if I kissed him with your cum on my breath?”

“Oh yea slut, that’d be super hot. Give me your phone and we’ll set something up.” Liv handed him her phone and he put his number into it. “You want to send me nudes several times a day. The riskier it is to take the picture, the hotter you think it is.”

“You might want to check your phone later, lover boy…I think you’ll be surprised.” Her voice thick with lust.

“See you Friday, babe.” Robbie ran his fingers through her hair, causing her to shiver with desire. “Gotta go see principal tits.”

“Ok sexy. Be careful, she’s on the warpath.”

“Don’t you worry your empty little head about it, slut. I got it covered.” Liv giggled in response, staring lustfully at his ass as he walked into the office.

Before he even got to the office door, his phone dinged. Looking at it, he saw it was a picture of Liv...an upskirt shot where she'd pulled away her panties so he could see her bald little cunt, visibly wet. Glancing over his shoulder, he chuckled to himself. This new toy was going to be great.
