"More sexytimes with your new crush, hm? And by that you actually mean 'More brainwashing into a helpless new servant for me to use,'" Sarah smirked and chuckled as she read the latest DM from Karyn. "I'm almost worry I overdid it!" she thought, not worried at all. "The poor girl's probably obsessed with me now."
It was an uplifting sight to see while scrolling through her socials; frankly, one Sarah felt like she kind of needed. She happened to read it right after a series of similar, but much more unwelcome, texts from her own boyfriend, Biff Meadows.
Hey Baby~
Thinkin About u~
Already finished up my homework for tonight, so...
Maybe I could come on over and help u with yours? ;)
"Oh, great. The 'Homework' roleplay again," Sarah had thought indignantly. "The things I put up with..." Her first instinct, before reading the DM from Karyn, had been to make up some excuse why it wasn't happening tonight, maybe send Biff a racy selfie to get himself off to as a consolation prize, and go on with her life without a boyfriend to placate for the next while. Truth be told, Sarah didn't even really like Biff! She liked the idea of Biff being her boyfriend, like just about every other straight girl in school did, sure -- he was handsome, cut like a Greek God, charismatic, actually pretty smart for a jock, and so on -- and more than that, she liked the idea of Biff being HER boyfriend. She liked how jealous the other girls got, seeing their Prince Charming crowning her, not them, as his queen, and she liked that they were the Power Couple™ of the school, the God and Goddess whom all the other Mere Mortals were privileged to live in the graces of.
The only problem with dating Biff Meadows, unfortunately, was dating Biff Meadows.
All this homework is just soooo hard :(
I neeeeeed someone big and handsome and smart to help me with it!
I PROMISE I'll repay u and stuff! I'll make it worth ur time! There must be SOMETHING I can do 4 u if u come over?
Pleeeeease~?
Sarah cringed internally as she hit send. Her reply to Karen, despite just being quick to-the-point business, had made her feel like the Queen of Everything and more importantly had given her the idea of what to do with Biff; but her unfortunately necessary replies to Biff, in contrast, just felt degrading. Biff was into degrading things like that: he liked the idea of having some ditzy, sexy airhead to be his submissive, drooling armcandy, and he liked being the Mr. Macho to swoop in and give her all the answers to her homework or whatever it was (never mind the irony that he himself had probably pilfered the answers off some nerd or something). "YOU'RE the Trophy Spouse, you meathead, not me!" Sarah wanted to scream sometimes. Swallowing her pride and playing the part when it counted was a necessary evil, the price to pay if she wanted to keep her social status where she wanted it and the bones to throw when training Biff to be her perfect pet boyfriend where she needed it. That was just how to play the social game, to her.
WAS just how to play the social game, to her. She dared not take off her new ring, not even for a moment, while changing into something to wear for Biff.
"Ollie Ollie Oxen Freeee~?" Biff was here. He'd let himself in as usual, just unlocked the front door and waltzed right in (not that Sarah's parents would care). "Where's my little baby girl~?"
"Oh em gees, you're finally here!" Sarah cooed back in that squeaky Valley Girl voice she wouldn't be caught dead using anywhere else. Just a little longer. "I'm up in my room, daddy! It's like, sooo super hard tonight, so like, I totally need you up here right now!"
"You poor thing... You should've called me earlier if your homework was giving you this much trouble, dummy!" Biff called back as he made his usual hike up the stairs, into the cavernous bowels of the McMillan Mansion. Once at the big double doors that led into Sarah's bedroom, he asked "May I come in?"
"I forgor..." came back apologetically. Sarah had NOT forgotten, of course. "And yes please! I'm like, all ready for you and everything!"
"'Ready for me,' hm~? Well, let's just see about that..." Biff pushed into the room and beheld a Sarah, sitting on her bed, in what pornography would call a "schoolgirl outfit" and what actual schools would call a "flagrant violation of the dress code": A pleated skirt in LPHS colors, so short it teased hints at her panties; a too-tight button-up top with the upper several buttons undone just to show off how her cleavage bulged out of her bra, all beneath a falsely boring beige jacket with no buttons done at all; hair pulled up into two cute twin ponytails, framing a face with fashionable cat-eye glasses she didn't actually need; long, translucent white thighhighs squeezing her shapely legs all the way down to her black platform heels; and on her face, she wore that practiced puppydog pout she knew Biff loved so much. Biff was grinning like a fool (for fool he was) at the sight. "My my my, you're beautiful as ever, babygirl! You must be really desperate for some answers, hm?" Biff waggled a few papers in his other hand: the assignments for the day, all completed and safe to copy answers from.
"Oh, daddy, you're like, totally the bestest!" Sarah pleaded with him. "I just, it's so much work, right, and like, I don't know who else to call!"
"Well, Dr. Meadows is always on call for you, baby~," Biff sauntered over and set the homework on one of Sarah's bedside tables. "But unfortunately, little one, those papers aren't free..."
"Oh, actually, um, I don't need those papers?" Sarah said, tilting her head cluelessly. "I had a different assignment today!"
This caught Biff off guard, but he humored her. "Oh? And what assignment did you need help with, baby?"
"It's just a few questions..." Sarah unbuttoned the lower bits of her shirt, then pulled up. "The first one's written here!" she said, indicating a spot just below her navel, where she'd actually written a simple math question directly on her skin with a dry-erase marker.
"Oh, I see!" Biff grinned. "Let me get down for a closer look~..." And with that, Biff was on his knees, between Sarah's spread legs, getting a very close look at her abdomen and the writing on it.
"Go time," thought Sarah, putting a gentle hand on his shoulder to keep him just where she wanted. That was the key; her ring tingled, and she felt her power over Biff grow somehow, when it touched him directly. She couldn't explain it, but somehow she just viscerally knew that, as long as that contact stayed unbroken, Biff was as good as putty in her hands. "And he doesn't have the slightest idea what he's in for!" She thought, watching him read.
"'A Linear Transformation is any Transformation that has what two properties?'" Biff read aloud. He raised an eyebrow; Mathematical Transformations didn't exactly make for good pillow talk, but certainly, Sarah must have had somewhere she was going with this. She was clever like that, after all. "Uh.... Hm..." Biff screwed up his face in thought a little. What was the answer here? It seemed like an easy enough problem, just basic vocab from math class a few days ago. But Biff didn't know the answer. How could he not have the answer? It would kill the mood if he didn't have a good answer! And he was a quarterback, not some knuckledragging lineman; this should be easy!
"Where, uh, did this question come from, baby?" Biff asked, to stall for time. "It doesn't look like anything your pretty little head should-"
"Advanced Algebra. The Linear Algebra unit," Sarah said quickly, more authoritatively than just a moment before. "I know that, like, more or less what they want is that it's an operation-preserving map, right, they're looking for Transformations that preserve Addition and Scalar Multiplication and stuff, but like, I'm totally unsure how general they want it to be? Like, of course it applies over any pair of real-valued finite-dimensional vector spaces, but like, why not over any pair of Ring Modules just in general? Would it be like, totes wild to bring some exotic Ring structures into this?" She asked, ring finger gripping a little tighter onto Biff as she said it, looking down at him.
Biff was stunned. He stammered, trying to think of something appropriate to say in response, but frankly, all of that had just went over his head.
"Biffie?" Sarah asked, tilting her head with that same cute curious look she had before. "Something wrong, baby?"
"N-not at all," he replied unconvincingly. "I just, I think you already have what you need, is all."
Sarah gave him that same cute look for a moment. Then, she "figured it out," and grinned. "Oh, Biff, my sweet baby boy! You thought you were going down on me, huh? And I bet that thought, like, it was so exciting, you couldn't think of anything else, could you?"
"...Was I not going down on you?" Biff asked, now himself much more confused than Sarah was pretending to be. His eyes darted down, from the writing on her lower abdomen to her skirt just below below it, the wide hips it rode on, her groin, her cameltoe... "Maybe the answers are hidden under here somewhere~?" Finding a second wind momentarily, Biff tried pulling her skirt down for a peek at the nether regions beneath...
...only for Sarah's big meaty thighs to suddenly snap shut around him, wrapping him in place with her legs. "Nope! That's the wrong way, dummy, you aren't getting out of your assignment that easily!" For good measure, she shimmied her skirt down around her legs wrapped around Biff, stretching the elastic of the waistband for an extra layer wrapping him up even tighter, and showing definitively that no, she hadn't written the answers on her hips or her thighs or anything. "Your eyes should be up here, baby!" Sarah unbuttoned her top a little more, and the second question of her little "assignment" became visible, higher up on her toned abs, and folded a little beneath the underside of her boobs, the exposure of which was now prevented only by a single heroic button of her "schoolgirl" outfit. Biff almost couldn't read it; the abs, the underboob, the striptease to the the body writing, all of it was getting exciting. How was he supposed to think about anything else!?
The actual question, when his head finally cleared enough to read it, was written in a curious boxy formation Sarah had drawn on herself in sharpie, like so:
| Any Linear Transformation from | one real-valued vector space to another |
|---|---|
| can be equivalently represented | with what other operation? |
A vertical column of 2 hearts in red marker was drawn just off to the right of the question. 2 more hearts had been drawn to the left, but for some reason Biff just couldn't figure out, they formed a horizontal row rather than a vertical column. Was that supposed to mean something?
"Well?" Sarah asked, the showy Valley Girl accent now gone. "Weren't you going to help me, you big dummy?"
Biff squirmed a little from where he was caught in Sarah's powerful thigh grip. "No fair!" he whined. "How am I, like, supposed to focus when I'm, like, all super hot and stuff!?"
Sarah actually laughed out loud. "You're looking right at the answer, you little baby!"
"But you've got like, superhot abs and totally awesome boobies and stuff! It's like, totally not fair to make me look at them when I can't like, look at them, or... um..." Biff had to stop to think. Something wasn't right...
"We've been studying this in this Math class for weeks now. Don't you know Matrix Multiplication when you see it?" Sarah jeered.
Biff didn't respond for a while.
"Biff!"
"What? Oh, like, totally, yeah it's matrix stuff, isn't it?" He stammered out, eventually, only just putting the thought together.
Sarah just sighed, pulled her skirt the rest of the way off her legs (leaving it around Biff's own waist), and then pulled him up onto the bed with her. He gave no resistance. "God, you're such a BOY!" Sarah snarled in open disgust at the word. "You think you're so big and smart and all this hot shit around everyone else, huh? But the moment a pretty girl like me shows a little skin at you you get all STUPID, can't hardly form a thought you don't immediately drool down her cleavage, don't you?"
Biff's dull eyes hardly seemed to comprehend, looking up to Sarah where she leaned over him. "But... 'm not stupid..." he muttered.
"Oh yeah?" Sarah challenged, not bothering to disguise her true bitchy feelings from him anymore. She took her faux-glasses off to look him right in the eye and said, "Well, I've got one more question left on my little assignment, stupid." Crawling atop Biff, straddling him, her fingers went down to the last button on her top. "It's an easy question. It's a really easy question. And you know what, I'm not even gonna make you answer it, because, I don't think you can even read it. Just try and see if you can even THINK straight once this comes off, won't you!?"
Biff just looked up at her.
"Say 'Yes, Mommy!'"
"Yes, Mommy!" Biff replied immediately.
"Good boy." The button came undone, and in a single motion, both the button-up and the jacket were off and thrown away. A second later, the bra came off too, exposing on one of her huge juicy melons the words "WHAT RHYMES..." and on the other, the words "...WITH MATRIX?"
Biff could not read it. He stared up glassy-eyed at Mommy's giant, perfect, bouncy titties hanging over him and couldn't comprehend a single word of the English language, let alone the word "DOMINATRIX."
