Yandere Human Teacher Diamonds x Teen Reader

A/n: yes. All three (not including Pink) would like to fuck you and keep you close at all times. And yes, I made it worse by making them teachers and you are the student. Enjoy~ also, part of this is inspired by something that happened in DiamondAuthority43 's yandere fanfic and I suggest you read it because it's amazing and they're working on a sequel. Ok, let's go!

~~~~~~~~~~~

You groan softly as you stumble into school, still rubbing the sleep away from your (e/c) eyes. It only takes you a few moments to gather your things and go to class, but you're already late. You don't really care. It doesn't matter if you rush in to justify why you're late. They're gonna give you detention anyway. You run your hands through your (h/l) (h/c) hair, tying it up into a ponytail. You walk into class and sit I your seat. "(Y/n)," Yellow says, calmly. Everyone calls her by her first name because it gets too confusing between her and her sisters, who all teach here. "I do not tolerate late students. I'll see you after school for detention."
"Yes, miss," you reply, gently trying to wake yourself up. While Yellow waits for all the students to answer the question she has written on the board, she grabs her phone and texts Blue and White.
Yellow: [we got her. We finally got her! Come to detention with me after school! We'll have her all to ourselves!]
Blue: [finally! I can stop practicing on the body pillow of her that we made. It's nothing like the real thing, is it?]
White: [should we still video her changing for gym? Since we have her now?]
Blue: [of course! We still need those for when she's not with us]
Yellow: [yeah]
White: [👍]
Yellow puts her phone down and gets on with class, anticipating the detention she has with you, her sweet (y/n).. The entire period, she listens to you hum and watches every single thing you do. She even gets stuck in a trance when you chew your pencil. She immediately rushes to you if you have a question, even if she's in the middle of answering someone else's question. She doesn't complain about the little doodles on the side of your page and helps you correct your mistakes, paying more attention to you than other students. She literally checks on you after talking with two other students every 30 seconds.

The after school bell rings and you gather your stuff from your locker, then head to detention. This is the first time you've gotten detention, so you're obviously curious about what happens when you're there. You arrive at the room and walk in, being greeted by Yellow. "Hello, (y/n)," she says. "Just take a seat. I have some things I want you to do while you're here, but I have to email another teacher quickly." You shrug and sit down, pulling out your sketchbook and drawing a picture of your cat, (c/n). Yellow pulls out her phone.
Yellow: [hurry up. She's here. You got our gift for her, right?]
White: [of course. Why wouldn't we take this opportunity to show her how much we care for her?]
Blue: [i'm so excited! We can finally claim her as our own!]
Yellow smiles and puts her phone away, watching you draw with lustful eyes. She watches every single detail. Soon, Blue and White enter, smiling oddly with their hands behind their backs. You glance up at them, hearing the door open.
"Oh. Hi Miss Blue and Miss White. How are you?"
"We're just perfect," White answers, slowly coming closer. "We brought you something to eat." She places a plate of a gorgeous meal, with a meat that looks unfamiliar to you, on your desk.
"O-oh.. You didn't have to. Isn't detention supposed to be a punishment?" Blue giggles.
"Not for you~" she replies. Yellow stands behind you and places her hands on your shoulders, slowly massaging them. You quickly tense up, confused for many reasons. "Just take a bite. We worked hard on it." You carefully pick up the cutlery and cut into the strange meat, then taking a cautious bite. It tastes weirder than it looks.
"Do you like it?" Yellow asks, still trying to loosen you up.
"It's...interesting.. What meat is it?" None of them answer. They just giggle. Blue hands you a small box, smiling.
"We got this for you," she exclaims, excitedly anticipating your reaction. You stare at the box before opening it and picking up your cat's collar, blood staining it.
"(C/n)'s collar? But I-" you immediately stop yourself and look down at the meal they gave you. You feel sick to your stomach and cover your mouth in both disgust and shock and fear. "W-why would you..?"
"Because we care for you, (y/n)," Yellow whispers in your ear. "So much that we'll kill anyone and anything that keeps you from us." Those words send shivers down your spine. You attempt to get up and run out, but Yellow holds you down, tightly gripping your shoulders.
"What's wrong, love?" White asks, gently taking your chin in her hand.
"Y-you're scaring me.. Please, t-tell me this i-is just a joke!"
"Why would we joke about this?" Blue queries, running her hands up your stomach and chest, making you tense more. "We love you, (y/n). We have pictures and videos and a body pillow of you. We've been waiting so long just to get a taste of the real you." You stare, fear dripping from your eyes in liquid form. White licks up your tears, smiling.
"Don't cry, dear," she pleads gently. "We're just going to love you and keep you safe." You begin to shake, get their hands off you, but it's no use. Blue begins to unbutton your shirt while White kisses you and Yellow bites your neck softly. You try so hard to get them off, but they restrain you. Blue happily plays with your chest, pulling your skirt down. You manage to pull away from White.
"P-please stop! This isn't right!"
"What's so wrong about loving you~?" White asks, grinning.
"I'm a teenager!! And you're all pedophiles!!" You quickly shut up and there's a few moments of silence before they start laughing.
"Us? Pedophiles?" Blue wheezes.
"Pedophiles are so much worse, darling.." Yellow explains. "They commonly go for children, not older teens. And they only like them for their looks. We like you for everything.." You start shaking again and try to push them away, but they slowly begin to fuck you while restraining you. (I'm sick and it's late, so I'm not describing that rn. Maybe I'll edit it when I'm better and have the mental capacity). After they finish, they send you home, leaving you feeling sick, horrified, angry, scared, sad, confused.. You slowly wander home, staring at nothing. You hide in your room and dread the coming school day that is to come in only a matter of hours.

Meanwhile, Blue, Yellow and White are ecstatic. They think they finally have you. They finally got to show you how much they care for you and love you. They even got to take your virginity (yes, you're a virgin in this. Don't complain. At least you're not pregnant). Blue goes to her room and acts like she's talking to you.......................but she's talking to a body pillow of you that is stuffed with your (h/c) hair from your brush and haircuts and that just falls naturally. "(Y/n), you're so funny! And talented.. And beautiful.. I'd do anything for you.. We all would.. What? I'm your favourite? Aww, you're so sweet!" Yellow walks in, giggling.
"Am I your favourite too, (y/n)? I am? Hooray!"
"But you can't have more than one favourite!" Blue complains, pulling on Yellow's arm.
"Yes you can!" White enters.
"Ladies, (y/n)'s special. She can have as many favourites as she likes. And, luckily, we're all her favourite." They smile and nod.
"And with that hideous cat gone, there's more love to share with us!" Blue notes, smiling.
"And once we get rid of all her friends and family, she'll only have love left for us! And only us!" Yellow exclaims. They smile and begin to fantasise as they all say together,

"Our perfect (y/n).."
