Brad threw his chemistry book into his locker, tearing the cover. Glancing at the inside of the locker door, he noticed a picture of Cheryl. “Stupid bitch.” He ripped off the picture and slammed the door as hard as he could.

Brad noticed a small girl standing quietly behind where the door had been. “Oh, hi Melanie.” Melanie was about as bland looking as she was smart, and Brad was pretty sure he’d heard she was tutoring the chemistry teacher. Brad ground his teeth. He didn’t want to waste time on the short geekette, but it was necessary. It always seemed that if he flirted with the plain ones, he scored sympathy points with the hot ones. “What’s up, gorgeous?”

Melanie blushed, as she always did when Brad called her that. Brad didn’t notice, her huge glasses bugged out her eyes so much that he never noticed much about her face. “Hi Brad. Congratulations about the game. Uh, sorry to hear about Cheryl.”

Brad smiled at mention of the game, then went back to grinding his teeth when he heard Cheryl’s name. He’d scored several touchdowns last night, making him the hero of the town. He’d never scored with Cheryl in the two years they’d dated, making him a giant virgin loser when she’d dumped him after the game.

“Thanks. You need something?”

Melanie hesitated for a moment, then looked up at him and stuck her hand out. “You’ve always been nice to me, Brad. That’s why I knew I could trust you with this.”

Brad looked down at her hand. It held a very crude ring with a big metal piece on it instead of a jewel. He almost laughed when he saw she was wearing a matching one on her hand. “Oh, I don’t think so, Mel. I just broke up with Cheryl and I need some time.” Time and a pussy that was worth being his first fuck. Goddammit, how did he waste so much time on one frigid bitch?

“I understand,” said Melanie, “but you’ll really like it. I made it to do stuff. Well, actually, mine does stuff, but you control mine with yours.”

Brad’s ears perked up. He wasn’t sure what she was talking about, but he had a feeling that there was an opportunity here. Brad thought about last month when he’d been lab partners with Melanie in biology class. A little flirting and she’d gotten him his first ever A+ with no effort on his part. “What kind of “stuff” does it do, Mel?”

Melanie paused a moment and shuffled her feet. “It makes changes. To me. And I don’t mind. You can make any changes you want. You have my total permission.”

Brad smirked. “Permission?” After a second he smiled and took the ring. Fantasies of turning Melanie into Cheryl and spanking her raw filled his head. “Naw,” he thought, “that can’t be what she means. Eh, what the hell.” He put the ring on and said, “OK Mel, what do I do?”

“Just concentrate,” said Melanie, “and think about the change you want to make to me.”

Brad smiled and thought about what the nerd girl would look like with better hair. His jaw dropped as he saw her hair change from a tangled brown mess to stylish waves of auburn.

Melanie smiled brightly. “I felt a tingling in my scalp! What happened? No, wait, I’ll go to the little girl’s room and look later. I want to be surprised! I’ve got to get to class before the bell rings, so how about we meet in the parking lot after school, OK?”

Brad just nodded and watched her run off. He didn’t understand what had just happened, but he knew it was going to produce fun of one kind or another. Then the bell rang. “Shit!” said Brad, running to Ms. Stockton’s class.

Brad leaned on his car and waited. He didn’t wait long, Melanie was almost running onto Ridgemont High’s student parking lot.

“Hi Brad!” said Melanie. “I love my new hair! I knew you’d think of something nice.”

“No problem, gorgeous.” Brad opened the passenger door and gestured inside. The girl stood still and stared into the car. “Hop in and I’ll give you a ride.” Melanie slowly got in, then Brad closed the door behind her and got in the driver’s side. “Are you going to need a ride back later?”

“No,” said Melanie, looking at her brown shoes, “I usually take the bus home. I’ve had my license for two years, but my Daddy still doesn’t think I should have a car. He’s out of town this weekend, so you can just drop me home after we’re done experimenting.”

“No folks, huh? Hey, how about we do this at your house, so we have extra privacy.”

“Uh,” Melanie stammered as a blush lit up her face. “OK. You won’t tell my Dad?”

Brad flashed his best smile at the girl, melting her as she looked up at him. “Promise, Mel, absolutely. So, why’d you pick me for this “experiment” anyway?”

Melanie stared out the passenger window and fiddled with her seat belt. “The initial input only works with two people. You’ve always been nicer to me than the other guys.” Brad nodded and thought about Melanie’s hot cousin Sally. “I just, I just figured that I needed some improvements, something to make the other guys nicer, too. You’re much more popular than the other people who are willing to talk to me, so you seemed like a good guy to help me look and act better.”

Brad thought hard about what she had just said. He absentmindedly slowed down until a honk from behind woke him up. Brad hit the gas, flipped off the guy behind him, and asked, “Act better? The rings affect the way you act, too?”

“Oh yes. I know most people don’t like talking to me. I thought you could help with that, so I built the rings so that they could change my body and my mind.”

Brad looked over at Melanie. Her hands were crossed over her chest and she was staring at her lap. “Hey,” he said, “I know a change that will help you out. Let’s lose the shy girl routine.” Melanie thought for a second, then gave a little nod, and Brad thought “You’re very outgoing, you don’t think about what you want to do, you just do it without worrying so much.”

Brad saw Melanie’s shoulders come down, even though he hadn’t noticed that they were tensed up before. She turned and looked at him with a relaxed, unafraid smile. There were so many little changes in her posture and expression that for a brief moment he thought he’d messed up and made a change to her body instead of her head. Somehow, she already looked more attractive.

Then Melanie placed her hand on Brad’s leg. “Yeah!” thought Brad, “This is definitely going to be worth the effort. Well, it’ll be worth it if she doesn’t turn out to be another cock teasing bitch.” Brad looked at Melanie, her new smile and new hair were making her look a lot better, and her hand felt pretty good on his thigh. Brad thought, “Fuck it, I’ll just make sure she’s not another ice queen.”

As they drove along, Melanie continued to talk. However, whenever she wasn’t giving the tall football star directions to her house, he ignored what she said. Instead of listening, he was busy thinking of any sexual hang ups she might have. Whenever he thought of something, he focused his thoughts on Melanie being more relaxed about those things. As he did this, Melanie’s hand started to rub slowly up and down his thigh.

They pulled into the empty driveway of Melanie’s house. Brad could feel that her stoking had made his cock very hard. He smiled, looked over at the girl in the glasses and thought “Pull my cock out and tell me exactly how great it is.”

Melanie immediately leaned over, unzipped Brad’s pants, and pulled out his erect penis. “Wow,” she said, “I thought they were supposed to be bigger.”

“Shut up! It’s huge!” Brad watched as Melanie’s eyes went wide with awe for his cock. Then he put his hand on the back of her head and thought, “Suck it.”

Melanie leaned further down, popped the dick in her mouth, and began sucking. “Wow!” Brad thought, “It took me over a year to get Cheryl to do this!” However, after another moment he noticed that the girl was doing nothing but literally sucking on the cock. “Well obviously,” he thought, “nobody has ever stuck a dick in her before. Does she even know what “sucking cock” means? What the hell would she have done if I’d told her to blow me?”

Brad started thinking commands to do certain things, and the blowjob got much better. Melanie sucked some, but not constantly, and she licked the head occasionally. Her head bobbed up and down with a slow rhythm. Then Brad realised that he didn’t have to think in words, he could just picture what he wanted and she’d do it exactly. Her hands came up to stroke the areas her mouth was missing, and she worked every part of him the instant he thought of it. Somehow, that made things both better and worse. Melanie was licking up and down the shaft exactly the way he wanted, but she was so responsive it felt like he was just jacking himself.

Brad reached down and pulled Melanie’s head up, then looked deep into her huge eyes magnified by her glasses. “Mel, no more instructions, just tease the hell out of my cock, OK?” Melanie nodded and went back to work. The nerd girl’s tongue flicked back and forth over his dick. As he got ready to cum, he thought “Mel, always swallow the load when you give a guy a bj,” then he shot everything he had as she eagerly sucked it up.

When she’d finished cleaning his dick, Melanie looked up at Brad and smiled. “Was that good? I’ve never done it before, so I guess that was one of your commands. That was an extremely interesting experience. Did you like it?”

“Damn,” thought Brad, “she gets chatty when she loosens up.” Aloud he said “Yeah, beautiful, you got pretty good towards the end. Zip me up and let’s go inside.”

Melanie smiled like she’d just been given a gold star and reverently placed Brad’s cock back in his pants. They got out of his car and went inside the house.

Brad looked around. The house was nice, but a little empty of furniture. “Is it just you and your Dad here?”

“Oh yeah, but he’s gone a lot. Business and stuff.”

Brad walked up close to the girl and pulled her glasses off. As she blinked and squinted, he thought, “Have perfect vision,” and watched as the grateful girl smiled up and him and opened her eyes wide. He was surprised to find that she was a little cute under the huge glasses. No makeup, and only a little cute, but that was fixable. As Brad tossed the glasses into the trash can, he said, “Let’s go to your Dad’s room.”

Melanie stopped smiling. “Oh, we can’t do that.” She looked nervously around the room, as if expecting her father to show up suddenly.

Brad put his hands on her shoulders and thought, “You love being a bad girl and breaking the rules. You’re horny as hell and you want me bad. You’re also going to do what I tell you from now on and not be a little bitch about it.”

Melanie looked up at the football player with a look of pure lust. “I’m sorry Brad, you’re right, fucking in Daddy’s bed would be so hot!” A huge flush covered her face as she said the word “fuck” for the first time in her life. Then she grabbed Brad’s hand and dragged him into her father’s bedroom.

When they got into the bedroom, Melanie made a clumsy attempt to kiss Brad. He pushed her back. “Slow down a bit, we need to do some stuff first. Before we do anything, take your clothes off and pose for me.”

Melanie frowned, but backed off. As she took off her clothes, Brad saw the first thing that needed to be changed, those little tits. “Double D” he thought, and watched at her breasts grew. The result was awesome. He wasn’t sure exactly how big Double D’s were supposed to be, but these were bigger and rounder than Cheryl’s had been, and that was good enough.

By this time the girl was undressed and had started striking naughty poses. Right now she had her legs far apart and was leaning forward, swaying slowly to move her breasts. Brad was impressed. Without inhibitions, she was actually pretty good at posing like a slut. Of course, a five foot tall little girl was barely worth looking at. “Taller,” he thought, and admired Melanie as she grew to about five foot eleven. She was still several inches shorter than he was, but she didn’t look like a kid anymore. Brad took a moment to appreciate Melanie’s long, luscious legs.

“You seem pretty happy with the results,” said Melanie. She put her hands behind her head and arched her back. “That smile looks like it’s about to split your face.”

Brad nodded. “C’mere, slut.” Melanie frowned a little, but came closer. Brad rolled his eyes and thought, “Enough of this nice guy crap. You love it when I call you names. The meaner and more demanding I am, the hotter you get.” Then he reached around and slapped her ass so hard it knocked her forward a step, pressing her against him.

“Ooh!” Melanie cried out, “that felt good. I don’t know what you did Brad, but that smack felt REALLY good!”

Brad liked how appreciative she was. Cheryl the bitch had needed endless compliments, but it felt nice to receive some for once. He concentrated on the tall, busty girl in front of him and thought, “Everything about me makes you hot, and you love telling me so!” He started to massage her glorious new tits.

“Mmmm! That feels so good, Brad! Oh yeah, you make me want your big cock in me right now!”

As Melanie ground her hips into Brad, he pushed her back. “Not quite there yet, cockslut.” The girl let out a little giggle at what he had called her. “Go ahead and take my clothes off me while a make a couple more adjustments.” She began undressing Brad greedily. He looked down at her and concentrated again, this time making her lips fuller and her nose just a little thinner. He cleared up the little bit of acne that she had and adjusted her eyes to be just a bit wider, with thick lashes. When she looked up at him he smiled, satisfied that he now had a supermodel.

Both their clothes in a pile now, Brad grabbed Melanie, spun her around and bent her over her father’s bed. “How’d you like me to take you from behind, cum sucker?”

Melanie quivered and her large boobs shook. “Oh God, you can take me any way you want, stud! You’re so fucking hot, you can, OH!” The football star slid his cock into her and began moving in and out, teasing her cunt slowly. “Oh god, that feels good! Fuck yeah! Why didn’t you screw me sooner, Brad?!”

Brad smiled. “Because you weren’t worth touching before today, you big titted bitch!” Brad concentrated on his new girl having infinite love, trust and loyalty to him as he stroked in and out of her pussy. He reached around and grabbed her breasts, positive that this was much better than losing his virginity to Cheryl would have been. Thinking of his ex-girlfriend made him speed up his stroke. He decided to get some pictures later to rub in Cheryl’s stupid face.

“FUCK!” screamed Melanie. “Fuck! Fuck! Oh fuck, your cock feels so big in me! Keep pounding my pussy! Oh god, it feels so good being a slut for you! You can fuck me anytime, as often as you want! Just don’t stop! FUCK THAT PUSSY WITH YOUR HUGE COCK! FUCK ME, FUCK MEEEE!!!”

Brad realised he was going to cum and then exploded less than a second later. He stopped stroking immediately and just stood rigid as he filled up his new toy’s pussy. When he was done he gave her a shove so that she fell on the bed.

“Oh,” sobbed Melanie, “don’t stop, lover, I need more! You’re so fucking hot, I need more of your big cock!”

“Well then shut up and finger yourself. You getting off isn’t my problem.” Brad looked down at her as she smiled and put her finger into her cunt.

“Oh, oh wow. This feels good, Brad. Is there anything else I can do for you?”

Brad burst into a big grin. Watching the former nerd girl frig herself was pretty hot. She was on her back and pushing her legs apart so he could see better. Brad loved how her boobs spread out on her chest, jiggling from the movement of her hand on her pussy. After watching for several minutes, Brad looked down and saw that he was getting erect again. “OK, slut. I know what we can do next.”

Being careful not to knock the girl’s hand away from her cunt, Brad climbed onto the bed and knelt down over her chest. “I saw this in a porno once, and I thought it looked like the coolest thing ever.” Brad grabbed his cock and started jerking it over Melanie’s chest. Then he lowered himself so that his cock lay between her big breasts.

As Brad pushed her breasts together and began to work his hips, he noticed the sweat glistening on his new bitch’s fine tits. “Nice,” he said, “my cock’s sliding in your tits really nice, whorebag.” She gave him another giggle when he called her a whorebag. It was so much fun making her squirm that way.

Melanie looked back up at him. “That feels nice to me too, Brad.”

Brad looked down at his slut. Her compliment didn’t sound that great to him. He also didn’t like how his cock was slipping out of the breasts so often. They were a pretty good size, but this could be improved. “Bigger, and a ton more sensitive,” thought Brad.

The auburn haired slut’s breasts grew even bigger. Brad looked at them the way a food-stamps family looks at a winning lottery ticket. “Shit yeah!” he yelled. He stroked faster, rubbing his cock in the breasts back and forth, back and forth.

As Brad resumed his stroke in the stripper-sized tits, Melanie’s faced started to contort. “Oh shit, that feels so good! Between your cock in my tits and fingering myself, CRAP! I’ve never felt this horny, Brad!”

Brad looked down at Melanie’s face and noticed that his changes had made her look like Cheryl. “Beg me, bitch! Beg me to titty fuck you like a cock-sucking little whore should!”

“OH GOD!” screamed the beautiful slut, “Keep fucking my titties, Brad, please keep fucking them! I need your huge cock in me! I need it in my pussy, in my mouth, and between my big tits! Fuck my tits harder, please!”

“You love having your tits fucked, don’t you, slut?” teased Brad. “Tell me why you love it so much.”

“Because you’re doing it! Oh god! Feeling your cock rub my tits makes me so wet. OH FUCK! I’m a big tittied slut who needs your fat cock, Brad! Please keep using your huge dick on me! PLEASE LET ME SUCK UP YOUR CUM!” Melanie arched her back and tired to roll around, but Brad had her pinned. “SHIT! YOU’RE SO HOT BRAD! I LOVE BEING YOUR SLUT! I LOVE HOW GOOD YOUR COCK FEELS, AND YOUR HANDS ARE MAKING MY BREASTS TINGLE LIKE CRAZY! DON’T EVER STOP FUCKING ME! GOD! IT FEELS SOOOOO GOOD!

Brad didn’t notice Melanie having her third orgasm of the evening. There wasn’t much way for him to, since it didn’t calm her down or make her want him any less. She kept begging, and he kept stroking his cock in her tits. The tits felt awesome in his hands, too. He could feel her nipples rubbing under his palms, and he loved watching all the tittie flesh jiggle as he pushed it around with his hands and cock.

“I LOVE YOU COCK SO MUCH! FUUCK MEEE!!”

Brad felt the pressure building up again, so he grabbed his slut’s head and jerked it forward. She responded immediately by wrapping her lips around his cock and sucking greedily. Brad pumped what felt like gallons of cum into her mouth. He looked down to see how much it actually was, but couldn’t tell since she had swallowed it all before opening her mouth again.

Brad rolled off his conquest and laid down on his side. He was exhausted. Melanie began stroking his back and his cock. He thought he heard her say something. He just ignored it and enjoyed the nice massage and the pleasantness of drifting off to sleep.

Brad woke up and looked around the room. “Where’d my slut go?” he thought. “Oh well, maybe she’s in the kitchen. I could use some food.” Brad lazily put his pants on and walked out of the bedroom.

He found Melanie in the living room, quietly sitting naked on the couch and looking gorgeous. Now that she was sitting up, he could see how her breasts had stayed fairly pert even after their last enhancement. Looking at his incredibly hot slave girl gave Brad an idea. Now that Melanie was fully programmed, what if he got the ring off of her and gave it to some other girl? Even if he had to grab her hand and shove the ring on her finger, he’d have her thanking him a couple seconds later.

Brad felt his cock harden and figured he deserved one more bit of fun before he left. “Ready to give my cock another sucking, slut-o-mine?”

Melanie looked up at him blankly.

“Cumslut?” asked Brad. No response. “Mel?” A sneer appeared on her face, and Brad said, “Aw, crap.”

“Reset timer,” explained Melanie. She looked away from Brad, staring straight forward with a blank expression again. Melanie breathed deep, flexing her gorgeous body in a way that made Brad twitch. “I installed a timer that would reset my brain six hours after the first command. I thought that after you made me less shy or funnier or whatever, I’d still need to go back to normal so I could properly evaluate the changes and reset anything that might cause problems. I’m pretty sure I mentioned that on the ride over here.”

Brad walked forward and tried to concentrate on Melanie being obedient, but all he could think about was how good her pussy looked and how much he wanted to kiss it. He also got a little distracted by the sensation of his cock growing a lot bigger than it ever had before.

“And,” Melanie continued in a slightly sing-songy voice, “I also made it so that the signal between the rings would reverse after the timer ran out. I figured that I could reward you for helping me. I had all these nice little fantasies of you doing things for me, me doing things for you, us talking until dawn and slowly falling in love...”

Brad really wasn’t listening, he’d knelt in front of Melanie and was concentrating on licking her incredible pussy. After he’d pleasured her for a minute, he felt Melanie’s hand start to stroke his hair. Brad pulled out his new and improved cock and started jerking off. Oh course he was thinking about how beautiful Melanie was as he jerked himself for her. He couldn’t remember ever meeting any other girls, only his beautiful lady Melanie.
