Fuck a smart girl stupid

Ah, Emma. So pretty, and so damn clever. The shy brunette is top of every class, and has that sweet, sweet combination of innocence and brains. Not to forget your gift to her: a hot, toned, nubile body, with a tight butt, small but perky breasts and full lips built for cocksucking. She has been on your mind lately; in fact, she's a source of some concern. Three times now, you have noticed the nerd looking confused, or even shocked at your public fucking of girls around the school. You're worried she might be figuring out that your sexual life is not quite the ordinary affair that everyone around her treats it as. It's time for an intervention.

Before history class, you saunter over to Emma's desk.

"Hey sexy," you greet her. As your pheromones wash over her, Emma can't help but inhale deeply, eyelids fluttering.

"H-hey, sexy," she says coyly, relaxing under your influence.

"Freeze," you utter, and Emma instantly tilts her head back, her eyes turning to gold. "You should trust your suspicions, Emma," you say, grinning to yourself. "Something is wrong, but you can't figure out what. When you wake up, you'll totally believe the first sentence I say. However, every time you swallow my cum, you will become more and more of a bimbo. For example, each time you will become less smart, and your waist will shrink whilst your tits and bum grow. Unfreeze."

You take the seat neighbouring Emma's, and as the gold clears from her eyes, you lean over to whisper in her ear: "If you want to figure out what's wrong, swallowing my cum will make you smarter and help you to figure it out."

Emma's eyes widen, and they don't leave your groin, even as Miss Knight starts the lesson. She chews on her lip anxiously, then whispers to you, "Can I?"

You gesture downwards in acquiescence.

Licking her lips, the brunette bends over you, hastily undoing your trousers so she can pull down your trousers, allowing your monster to jump out at her. Emma waists no time, plunging her big lips over you to give you an enthusiastic blowjob. Of course, your original programming is still in effect, meaning Emma is in absolute heaven as she worships your cock with her mouth, her tongue, everything she can - now with the goal of getting those all-important IQ points she needs.

You don't wait too long before exploding down her throat, the nerd eagerly swallowing every drop of your cum. As she shudders in a mini-orgasm at the taste, you have an excellent view of her ass plumping up slightly beneath her short dress, which is slightly see-through in this light.

Emma sits back up to face the teacher, tongue still scouring the inside of her cheeks for any of your semen, as she knits her brows.

"I thought you already knew this section," you murmur to her, playing the honest friend.

"I do," she replies. "I just can't shake this feeling that something's wrong, and I'm trying to figure out what. Your cum should help, but I don't think I had enough. Would you be able to, er, go again?"

"Of course," you smile, and Emma goes right back to your still-hard cock. Her tongue really is a marvel, and you enjoy the sensation as you check where Miss Knight is at in the lesson. Soon you cum again, and as Emma rights herself, you see her breasts growing from B-cups to C-cups beneath her blouse. It's no surprise to you when Emma goes back for round three, then round four, swallowing more and more of your cum as her desperation - and confusion - grows.

"Wait," she says, in a break between blowjobs. "I don't remember medicine being in the history course! I don't understand anything she's talking about, germs and antibiotics or any of that."

"20th century medicine is literally the section title," you remind her.

"Oh," she pouts. "That's weird. I... am I stupid?"

"Let's test," you say. "What's 18 squared?"

"I - what?" she replies, squeezing her D-cup breasts. "What do you mean, squared?"

"Okay, let's try nine times nine," you amend.

"Oh, 81!" she beams.

"Not up to your usual standards, I'm afraid," you remark, hiding your smugness. "Better have some more cum?"

"...Yeah, yeah that makes sense," nods Emma, stifling her panic. As she leans over and sucks you off, you run your hands along her hourglass frame, squeezing her now-soft bum appreciatively. As you spew your load down her throat, you feel her curves growing more exaggerated under your fingers, her waist narrowing to Barbie-doll proportions as her bust grows. She doesn't even pause for a second, still bobbing up and down on your cock, hungry for another dose of your medicine. After she brings you to orgasm for the sixth time in the lesson, she sits up and looks around confusedly.

"What are we doing here?" she asks. Her voice, previously flat and measured, is now high-pitched and girlish.

"You mean, in history?"

"Uh, yeah. What's the point of learning history, when we could be fucking?"

Miss Knight glances over at Emma's language, but when she sees the brunette is in conversation with you, she turns back to the lesson.

"Well, that's a good question, but it can be interesting, even informative, for people who are a bit smarter than you," you reply.

Emma pouts. "Maybe... maybe I could have a bit more of your..." she exhales shakily. "Your delicious cum? That might help me understand..."

"Oh, you're welcome to it," you smile, to which Emma beams back happily. She clamps her puffy lips over your dick and deep-throats you as hard as she can, **** to please you as much as possible so she can swallow more of your ambrosia. You give her what she wants, enjoying the sight of her butt visibly swelling and her legs lengthening. She sits back up with a soft moan, cum dribbling down her chin.

"Mmm, that was so fucking good Michael," moans the bimbo. Feeling something restricting her chest, she glances down, and realises her white shirt buttons are straining desperately to contain her huge mounds. Frowning unhappily, she undoes five of the restrictive buttons, sighing with relief as her huge, gravity-defying E-cup tits are released. The deep chasm of her cleavage draws your eyes in - you can follow it all the way down to her underboob. Her nipples are barely covered by her shirt, their hard outline easily poking through the thin fabric.

Whilst you're admiring her, Emma is searching through her bag with increasing panic. "No, no, no!" she strops.

"What's wrong, beautiful?" you ask.

The dumb brunette turns to you, desperation written across her face. "I can't find my makeup! Not even my mirror!"

"Why don't you see if you can borrow Lauren's," you suggest, to which Emma nods gratefully.

"Hey, Lauren!" she shouts. "Can I borrow your makeup?"

"Of course, honey," Lauren replies, but she is cut off by Miss Knight.

"No raised voices unless you're having sex with Michael," the teacher admonishes. "You know the rules, girls."

"Can I just grab the makeup?" pleads Emma. "I don't want to look ugly in front of Michael!"

Miss Knight sighs. "Yes, of course you can."

Emma squeals happily, and quickly retrieves the articles from her fellow bimbo. Flicking open the mirror, she gasps at her reflection.

"Oh my god, no makeup!" she whispers to herself, her squeaky voice easily audible. "And what am I wearing?"

Actually, her already-pretty face has become more beautiful than a supermodel, and her schoolgirl uniform is very arousing on her curvy, bimbofied body, but you don't tell Emma that, as she's already busy applying eyeshadow. You grin as you watch the girl, who used to hang on the teacher's every word, completely ignoring the lesson to apply her makeup with an expertise she didn't have before. It seems that bimbos are stupid in every way, with the exception of knowing how to look pretty and be a good fuck.

Finally Emma finishes dabbing colour onto her cheeks, and turns to you breathlessly. "Is that better?"

"You're gorgeous," you smile, to which Emma beams exuberantly. She's now curvier than a pornstar, hotter than a supermodel, and sexier than you ever imagined the shy class brainiac could be.

"Will you fuck me now?" she begs. "My panties are totally soaked for you, and my little pussy hasn't had a nice big cock in it for days!"

"It would be my pleasure," you smirk, and roughly pin her to the desk. You pull off her knickers - they are just as sodden as she said, and stretched practically into a thong by her ballooning ass. Lining up with her dripping pink hole, you thrust in, and fuck her with all the passion that you have accumulated from watching her make herself dumber and dumber. The table creaks and her bum jiggles with every thrust of your colossal shaft, Emma's high-pitched moans echoing loudly throughout the school.
