So the world in question is a sort of what-if where technology went forward and culture pressed on in a familiar way except the baseline social expectations are so extremely misogynist that it's considered radical action to demand not to give your boss a blowjob in order to get hired/a raise. Girls are expected to wear sexy clothing to the point where they just get kids wearing it from the start because there's no point setting false expectations. Boys get to dream about being firefighters and astronauts and girls get shown pictures of Hooters waitresses and secretaries, "and if you're very ambitious you might 'work under' an important man!"

By middle school it starts being important for boys to pick out a girl to be their bitch, after which they'll be assigned a school choker that says "[Name], [Student]'s Bitch." It's a practice made to engender the idea in both that female success is inherently subservient to male success. The current feminist fight is to get "bitch" renamed to "concubine," and you're considered a wimpy/sensitive boy if you call your school-assigned girl-slave that instead. There are no sexual harassment protections- only that you're not allowed to slap another boy's bitch on the ass unless she misbehaves. 

In this fantasy I've done all I can to circumvent the rules. I wear button up halter top dress shirts that are only tight enough to see my nipples, forgoing a cleavage window in direct violation; I wear shorts that just barely cover the entirety of my buttcheeks despite the dress code stating they must show "2 inches or more." Teachers and students are constantly popping my shirt buttons open or giving me wedgies, and the beginning of every school day the principal forces me to put on wedge sneakers instead of my flats. By all means I'm absolutely dressed like a whore at the start of the day, but I show a "serious disregard for tradition" and a "troubling obsession with scholastic achievement and an avoidance of female responsibilities." Meaning I get good grades instead of blowing my teachers.

I befriend this small, nerdy boy. He's a nice, mild boy who's cute if a little twerpy, and we've been friends for years. Over time, I convince him to help me out, and he claims me as his bitch, making sure I can't be claimed by some jerk in the class. The main conflict is that after the claiming happens, the school starts introducing weekly activities where boys do things to their bitches to "tame" and "train" them, with help from the staff. I've come up with a workaround, wherein if this boy says that he "passes," then I get off scot-free and can keep studying instead. 

... But his temptation is so hard. He sits there watching as his classmates get their dicks wet, moaning and busting and high-fiving each other and slapping their concubines' butts on the way out, and... he passes. I breathe a sigh of relief.
Then it happens the next week.
And the next.
And the next.

When finally, at the end, with his turn up, he shivers, and cracks. They ask him how he wants his bitch, and he hurriedly shouts "Vacuum gloryhole!"

"W-... Wuh?!" My eyes widen in horror. He hides his head under his book, his eyes too hungry not to peek out. The staff grab me by both arms, shove an O-shaped plastic mouthguard in so my brace-faced teeth can't shut all the way; tear my clothes off; put me in a pose on my hands and knees with my ass and high heels up in the air; lower a rubber vacuum sandwich seal over my body, turning me into a shiny rubber statue version of myself... and shove a plastic tube against my mouth and pump it hard, swelling my lips up.

The whole class watches as I'm reduced to a drooling cocksleeve, the kid's backed-up sloshing nuts slapping against my neck, chin and chest as he savors the suction and soft lips on his dick, every thrust making extremely embarrassing sounds I'm mortified to hear but unable to see. The other boys laugh and cheer him on, loving the sight of this little dweeb dominating this stuck-up girl and her radical ideas. He cums and cums and cums in my mouth, and every time I try to spit, a boy or a staff member slaps my ass to shock me into swallowing. 

"Hey dude, can I buttjob your bitch?? I've always wanted a chance at that ass."

"Yeah me too, I wanna jizz on her ass and back!"

"Uh..." he flushes, having finally gotten some positive attention from the other boys. "... Yeah!"

It's a free-for-all. I'm reduced to a quivering cum-covered fuck sock, humiliated in front of the entire class, every boy I told to stuff it having busted on or in me. The teacher adjusts his tie. "Let that be a lesson, girls! You're always gonna put out eventually."

In the sexist AU I've got rattling around in my brain the damsels in distress aren't just tied up or put in mortal danger- they're implied to be force fucked. This implication is not subtle; they're put in 'slave girl' outfits, chained to beds, and in plenty of cases their shadow's silhouette is shown on the wall getting fucked against their will, while the voice actress makes struggling noises. 

The commonality of this practice has led to the term "getting shadowed," and in order to indoctrinate young girls "maintain traditional gender roles," any female character that's been a little too strong or capable or just hasn't been kidnapped will inevitably get Get Shadowed extremely hard. 

Such an episode will inevitably end with the girl in question thanking the male main character for rescuing them with sex, effectively Getting Shadowed by the Good Guys and this is framed as positive and correct. The intro theme to the cartoon is playing and the credits are rolling, nevermind how she's making the same laborious struggling noises as before and the fact that none of her bindings were undone.

Her allies will inevitably roll out the "You know you look pretty good in that thing! Maybe you should wear it all the time!" joke.

This encourages a kind of play where they'll mimic what they saw in the cartoon by pointing a flashlight at two of them dry-humping.
