#nsfw #femsheith Girls-only school AU

Keith is expelled from her old school for smoking and Heith is recommended to transfer her to a more strict religious school. He wouldn't want this for his girl, but he is left with little choice.

The nuns cross themselves as Keith walks by in her worn out leather jacket with cigarette burns in several places, hair ends dyed pink and ears pierced. The girl also refuses to follow through with dress code, claiming she has no suit jacket.

When the nuns call Heith, he only indulges Keith, saying money is tough right now every time, until one nun snaps and lets Keith take one from donations. It sits loose on Keith's small frame, but at least they stop nagging her about that

Heith still sneaks Keith pack of cigs when they get to see each other.
And Keith keeps it strapped to her thigh, under her not so pristine skirt.
That's how they meet with Takako Shirogane, the school's star stud and soon to be a grad.

Keith's thigh is still exposed as she holds the cigarette between her lips. She eyes the girl, plucking it from her mouth to speak.
"You gonna rat me out, good girl?"

Shiro seems to study Keith for a moment before advancing further, her eyes glisten behind glasses.
Slender fingers slide up Keith's thigh before stealing last cig from the pack. It looks like she would advance further, under Keith's skirt, but Keith takes a step back.

"I think I will let it slide for now, dolly."
She waves cigarette at Keith and tucks it into her pocket.
Keith is left hanging, trying to process the fuck just happened. Later, she will learn that she was chosen by Shiro.

Shiro is used to have anyone she wants, she doesn't like chasing. But one particular girl makes her run after her like she's never before.
The nuns are quick to agree to trust Keith in Shiro's hands, thus making her "Keith's older sister".

First thing Keith does when she sees Shiro is press her up against the wall..
"You think I could use some self-discipline, dear 'sister'?"
The air between them fills up with electricity as soon as Keith speaks those words.
Shiro's eyes darken just a bit.
"Yes, I believe so."

She uses the moment of Keith's hesitance, as she expected Shiro to dance around it, it seems. Keith's easily picked up and thrown over Shiro's lap on the tiny couch
"Wh-" Before Keith can react, her skirt is yanked up, flashing her pale ass that soon receives a hard smack

Keith flinches hard, as it came completely unexpected. She tries to avoid the second smack, but Shiro keeps her pinned with grip on her unruly hair.
"Are you gonna behave, Keith?" She coos, sweetly, rubbing the reddened flesh.
Keith grits out.
"No."
And that's the wrong answer

Keith has only fucked around with 'bad girls' before, so when Shiro showed interest towards her, Keith thought she was simply outside her type with how pristine she looked, her shirt always tucked into long skirt, dark hair impeccably brushed back. Stoic goddess, unattainable.

Now she was the opposite of the image, she looked as wild. Keith begins writhing and sobbing in Shiro's lap, heat coursing through her, overwhelming. Keith thinks how gravely wrong she was. Shiro keeps spanking her over and over until finally, Keith whimpers out a broken "yes".

Surprisingly (not), after Shiro picks Keith up for mentoring, the girl stops getting into trouble so often.
The nuns are in awe, wondering how such changes were
Shiro only smiles.
"I have my methods"

Whenever the time of their session comes, Shiro pats her lap, and Keith knows to lie down and let her wreck her..
She goes as far as to pushing vibe in Keith's sloppy pussy after opening her up with her (apparently pierced) tongue as reward for behaving.

When Keith has to present in front of class, she can feel Shiro's careful eyes on her as well as her playing with the remote. Keith tries to keep her voice in check, but too soon all of her efforts are deemed useless

Shiro pushes the vibe to max and Keith has to hide her face in the crook of her arm, pretending to sneeze as warmth trickles down her leg.. Thankfully, nobody but Shiro behind teacher's table can see the little pool forming as the lights are off..

Keith excuses herself and Shiro follows right after her, saying something about Keith not looking good. She licks her clean in the toilet cabin and gives Keith peeks of her breasts filling the bra that looks small compared to them. Keith cusses and sucks on her pierced nipples.

Shiro was once a bad girl just like Keith.
