Tirek is Diamond Tiara's substitute maths teacher. He wants to subtract her clothes, divide her legs, and give her a square root. And then some sort of joke about multiplication. Yeah, except this is a rape story — nothing funny about that.

Mr Tirek is a substitute maths teacher at Canterlot High School. One of his students, Diamond Tiara, is way behind on her work, so he offers her a way to make it up. She goes along with it, though not entirely willingly.

Diamond Tiara is aged up to 18, and in her final year at CHS. Contains: degradation, hair pulling/trichophilia, coercion/rape, slapping and other violence, mild bondage, very mild gore, clear violations of teaching ethics.

In which Tirek Blatantly Disregards the CHS Code of Ethics for Staff–Student Relations (Section 49, Paragraph 7, Sub-Paragraph 5)

Diamond Tiara said goodbye to Silver Spoon near the classroom door. “Bump bump, sugar lump rump” they recited under their breath while kissing each other on their cheeks. It was a silly little tradition they’d carried with them since elementary school.

Diamond pushed ahead of the throng of other students filing into the room and made her way to her usual chair, where she pulled her pens and notebook out of her backpack.

A red-faced man with salt and pepper hair walked into the classroom and began setting up.

Diamond yawned, doodling in her notebook — just swirls, flowers, pretty patterns… nothing of importance.

“Okay, class, I'll be teaching you maths for today,” came a deep and deeply irritated voice from the front. “Your regular teacher apparently has a slight cold and cannot be bothered to come in.”

Diamond hastily put her phone away into her pocket, and looked up to see that the unfamiliar teacher had scrawled his name on the whiteboard at the front of the classroom. Mr Tirek — strange name, sounded Middle-Eastern.

“First things first: I have this homework to return to you all.” Tirek circulated the class, handing out sheets of marked homework to the students.

Diamond Tiara awkwardly played with her hair and counted the tiles on the ceiling. In her other subjects, she’d normally chat with Silver Spoon, but Silver wasn’t quite good enough to get into the advanced class at maths.

Tirek arrived at her desk and tossed the last sheet of homework in front of her. “An F, Diamond.”

Diamond might have been smart, but she could be pretty lazy. “I was tired.”

Tirek sighed. “See me after class.”

Those goody-two-shoes brats Apple Bloom and Sweetie Belle started whispering together. Diamond concentrated, trying to hear what they were saying — no doubt they were gloating over her misfortune.

The teacher returned to the front of the classroom and started showing a slideshow on the projector. “Welcome to the wonderful world of matrix algebra,” he read.

Diamond rolled her eyes and returned to her doodling.

* * *

“Okay, I'll see you all tomorrow. Class dismissed.”

Diamond Tiara remained in her seat while the rest of class left. As Scootaloo passed, Diamond accidentally stuck out a foot while stretching, causing Scootaloo to trip, dropping her books and pens, and nearly landing on her face. Apple Bloom and Sweetie Belle hung back for a few moments to help her pick things up.

Tirek waited until the other students had left, then shut the door behind them, turning the key in the lock. He walked towards Diamond’s desk. “I thought they’d never leave,” he muttered.

“So…” Diamond said, trying to break the uneasy silence she noticed had descended upon the room.

“Diamond, is this homework some kind of joke?”

Diamond shrugged. “It’s like this with all my classes. I just have issues with homework.”

Tirek pulled up a chair putting it in front of Diamond’s desk. He straddled it, facing her. “It has to be the worst effort I've seen in months. Another F. You're going to fail this class, you know?”

“Why do you care?” Diamond asked. In truth, she was somewhat intimidated by the man — he was tall, and clearly worked out a lot. His eyes showed not even a hint of kindness. But Diamond was not the kind of girl to let such feelings show. “You're not my teacher,” she added confrontationally.

“I am for today. And probably the rest of the week. If you'd got a higher grade on this paper… maybe a B… it would be enough to save you. Your overall grade would still be low, but you wouldn't be failing the class. This is your senior year — it’s important stuff. If you don’t pass this class, you’ll never get into a decent college. I’m surprised your regular teacher hasn’t had this chat with you.”

Diamond looked at her watch. “Can I please leave? I'm going to miss my bus.”

“There will be other buses. I'm talking about your future here, you stupid girl.” Tirek rolled his eyes.

Diamond’s jaw dropped. “Excuse me?! What did you say?”

Tirek looked at her. “I said there will be other buses.” He stood and started pacing around her desk. Diamond swivelled her neck this way and that, trying to keep her eyes on him while he spoke. “If you had a little more intelligence, you might realize that I'm offering you an opportunity here.”

“I'm not stupid,” Diamond objected. “I just have no energy to do homework.”

“Lazy then. Stupid and lazy.” Tirek continued to pace around.

Diamond looked at the man, trying to figure him out. “What's your issue?”

Tirek stopped walking. “I'm going to give you an opportunity to bring your grade on this paper up to… let's say a B, shall we? An A might look a little suspicious given your track record.”

“What, like extra credit? I don't think you can assign that.”

Tirek jabbed a thick finger at the paper still on Diamond’s desk. “What if some of these wrong answers… and all of these questions you haven't even been bothered to answer… miraculously ended up as the right answers?”

“I guess so…” Diamond sounded a little unsure.

“All you need to do is a few favours for me, and I can make that happen.”

Diamond raised her eyebrows. This Mr Tirek seemed pretty reasonable — maybe he wasn’t so bad after all. Perhaps doing him a few favours could even be to Diamond’s advantage — her mother, Spoiled Rich, had always drilled it into her that it was good to have friends in positions of authority… and this Mr Tirek was certainly authoritative. “Sure. Like what?”

The substitute teacher gestured around the room “First, help me pack up the classroom. I’m new here — I don’t know where anything goes. You can start by closing all the blinds on the windows.”

Diamond shrugged, getting out of her seat. “Kay.” She walked around the room, shutting the blinds.

Tirek watched her reaching up, standing on the tips of her toes to get to pull the blinds down. He admired the way her skirt clung to her body, and how her little yellow jacket didn’t do much to hide the shape of her perky breasts. As she shut the last blind, he gave Diamond her next instruction. “Now I need you to take off your clothes.”

Diamond spun around to face him. “What?!”

“Look… you might be an idiot, but you must at least realize you have one thing people are interested in.”

Diamond looked at him with an expression of disbelief. “Excuse me?”

Tirek folded his arms, leaning back on a desk. “You're cute… well… cute-ish. You're never going to amount to much else, so why not put the one asset you do have to good use?”

“My asset?!” Diamond’s disbelief turned into anger.

“Yes, your body,” Tirek stated matter-of-factly.

Diamond grabbed her backpack and marched towards the door. She was going to go straight to Principal Celestia’s office… if Principal Celestia was still here at this time of the afternoon … or if she wasn’t, Vice-Principal Luna had a reputation for working late into the night. She’d still be here for certain.

Better yet, she’d get her dad to talk to the school district. Filthy Rich had a lot of sway with the people who counted. She’d make sure this substitute teacher never worked in the Canterlot area again.

Tirek watched the girl walking towards the locked door. Diamond jiggled the handle. “What’s wrong with it?” she muttered. Tirek walked up behind her stealthily. Diamond frowned, tugging harder at the door handle, while her plans for going to the authorities evaporated.

Tirek grabbed Diamond by the shoulder, spinning her around and pushing her roughly against the door, the handle digging into her back. “This is going to happen, one way or another, Diamond,” he hissed.

“Hey! Let me go!” Diamond squealed.

Tirek let go of the girl and went to sit on the edge of the large desk at the front of the classroom. “Now, take of your clothes, like a B grade student does.”

“No.”

“You can take off your clothes like a B grade student, or keep them on like an F grade student.”

“No!”

Tirek stood up and pulled Diamond’s backpack off her, throwing it into the corner. “You need me to help you with those clothes? Poor little Diamond, too stupid to dress and undress herself?” Diamond’s jacket had come half-way off with her backpack, and Tirek slipped it the rest of the way off her.

“Stop it…”

Tirek grabbed at her shirt, pulling on it. Diamond slapped his hand away, edging away from him. “Now that's it, you stupid slut,” he growled. “I didn't want to resort to violence, but you've just made me.” He pushed her back against a wall and started unbuttoning her shirt.

Diamond squirmed. “I said stop it!”

“This is your only chance to pass this class, so shut up and behave like a good little slut, or I'll have to make you.” Tirek continued unbuttoning her shirt all the way to the bottom.

“I don't care if I failed the stupid paper!” Tears started to brim in Diamond’s eyes. “This is just sick!”

Tirek pushed the shirt off her shoulders. “Don't pretend you don't want it. I saw the way you were looking at me in class.”

“I was not doing anything!” Diamond crossed her arms across her chest.

“Oh come on! All you girls want it…” Tirek yanked down Diamond’s shirt, pulling it off her completely and dropping it onto the floor.

Pankicking, Diamond kneed him between the legs. Tirek doubled over in pain, grabbing Diamond’s shoulder on the way down, and pulling her to the floor. He groaned, clutching at his crotch. Diamond struggled, trying to crawl away. Tirek climbed onto her, pinning her shoulders down and kicking away a couple of chairs.

“Help!” Diamond shrieked.

Tirek pushed her down flat against the floor and pressed an elbow into the back of her neck. Diamond thrashed around. Tirek flipped her over onto her back and pressed his forearm against her neck. She went still to avoid being choked.

Tirek used his other hand to start unbuttoning Diamond’s skirt. She reacted with another swift knee to the groin. “Stop!”

“Stupid bitch!” Tirek shouted, slapping her hard across the face.

Diamond cried out in pain, putting her hand to her cheek and stroking it softly.

Tirek stood up, grabbing the hem of Diamond’s skirt and yanking it down. Diamond made a feeble attempt to hold onto the garment, but it was a lost cause. Tirek flung it into the corner.

The substitute teacher kicked his student in the side, winding her. He grabbed at the waistband of her panties while she groaned and curled into a ball. Though not easily, he managed to wrestle the underwear off her legs. Reaching down, he unfastened her bra, releasing her small breasts. Diamond was in so much pain that she barely registered him pulling it off.

Tirek stood up straight. “See, that wasn't fucking difficult, was it, Diamond?”

“L–Leave me alone,” Diamond stammered.

Tirek towered over her. “Get on your fucking knees, like the stupid little slut that you are.”

Diamond merely shook her head, curling into a tighter ball.

Tirek leaned over, grabbing a fistful of her hair and pulling her upwards with force. “On… your… fucking… knees.”

Diamond screamed, lashing out at him with her fists. Tirek reacted by pushing her backwards, slamming her head into a desk. Diamond cried out in pain, then, dazed, slumped to the ground. Tirek bent down, lifted her up, and deposited her on her back on the nearest desk.

“N–No…” Diamond muttered as she watched Tirek unfasten his belt. He made a loop with it, grabbed her arms, and tightened the loop around her wrists. He pulled her hands over her head, tying the end of the belt to a table leg. Diamond weakly kicked her legs in his direction.

“Stop pretending you're not enjoying this, slut!” Tirek stood between her legs and pushed his trousers and underwear down. Diamond squeezed her eyes shut and crossed her legs lightly, but the well-built teacher simply pushed them apart. “Nice try. Maybe you ought to put in more effort during your gym classes too.”

Diamond whined.

Tirek pushed his cock between Diamond’s legs, entering her pussy. “Sheesh, you're dry. Can't you at least make a bit of an effort to make this enjoyable for me?”

Diamond mustered up her strength and kicked Tirek hard in the stomach, knocking the wind out of him.

“Ooof!” Tirek took a couple of steps back to avoid falling over. He circled around the desk, away from her flailing legs. “So you like it rough then, bitch?” He slapped her hard on the cheek, making her whimper. He slapped her again, this time on the breasts. Diamond struggled against her bonds.

He took his cock and slapped her in the face. “Open your eyes,” he commanded. “You want to see this!” As she peeped open an eye, he slapped his cock down again, the head hitting her in the eye. Diamond cried out and shut her eye quickly, jerking away.

Tirek grabbed a handful of Diamond’s lavender and white locks, winding it around his erect cock. He started stroking his shaft up and down in his fist, giving himself a hairjob. “You like that?”

Diamond Tiara, though her eyes were closed, could feel what was happening. She shook her head.

“Come on,” Tirek chuckled, “beg me to stop!”

“Please,” Diamond whispered, “just let me go home.”

Tirek moved his fist faster, pumping his shaft, pulling on Diamond’s hair, and positioning the head of his cock over her face. “Yeah, that’s good. I wanna hear you beg.”

“J–Just stop,” Diamond pleaded, slightly louder, opening her eyes.

Tirek clamped his free hand onto Diamond’s throat, pressing down, still masturbating with her hair. Tears rolled down her cheeks. He moved his hand up her neck and over her chin to her mouth, then used his fingers to force her jaw open.

Diamond had lost the will to try to stop him. He was bigger than her, stronger than her, and in a position of authority. What could she ever do?

Tirek grunted and shot a jet of cum over her chin, lips, nose, eye, forehead, and hair, some of it going into her open mouth.

Revolted, she spat it out.

“Don’t be fucking rude, bitch. Drink it up.” He used a thick finger to push cum and saliva from her chin into her mouth.

She stubbornly spat it out again, shutting her mouth tightly and shaking her head.

Tirek slapped Diamond across the cheeks. “You ungrateful bitch! I'm trying to teach you how to succeed in life.”

“I–I don't see how this teaches me anything,” she whimpered.

“You're stupid, you're talentless… the only way you're going to get anywhere in life is whoring yourself out.” Tirek walked back between her legs, casually parting her thighs.

“That's not true!” Diamond scowled, the red hand-print on her cheek beginning to fade.

“You think so? That just shows how stupid you are.” Tirek stuck his thumb roughly inside her pussy. “Still too fucking dry,” he muttered, beginning to move it in and out a little.

“S–Stop,” Diamond pleaded, trying to shut her legs, but Tirek held them apart.

Tirek kept going, and used his fingers to rub her clit. “What? You don't like it?”

“N–No.”

“That's cos I've hardly got started. Just relax, you'll enjoy it — they always do.” Tirek switched to pushing two fingers deep into her pussy.

“You've done this before?”

“Of course I fucking have,” Tirek sighed, slipping a third finger inside her tight pussy.

“That hurts!” Diamond squealed. “You sicko.”

“It'll loosen you up. It's like exercise — no pain, no gain.” Tirek moved his fingers faster.

“Stop! It's just making things hurt more!”

Tirek rolled his eyes. “This is taking forever.” He spat on Diamond’s pussy, massaging the saliva into her hole, then looked down at his erect cock. “Well, I'm ready again, so that'll have to do.”

“Please,” Diamond begged, “please don’t!”

Tirek ignored her, holding her pussy lips apart with two meaty fingers and pushing his hard cock between them. He moved his hands to Diamond’s thighs, holding them down to prevent her from kicking again. He sighed happily as his cock sank slowly into her warm, inviting pussy.

“Please,” Diamond pleaded as she felt his length filling her up.

Tirek moved his his hips back and forth, his cock sliding in and out of her tight passageway. “You know, I do think you're starting to enjoy this. Definitely a bit wetter down there, aren’t you?”

Diamond scowled. “I am not!”

“Why you getting so wet then?” Tirek grinned.

“It's your saliva,” Diamond said, squirming away from him half-heartedly.

“That barely made any difference.” Tirek drew a deep breath. “No, this is you. I can smell you, you slut. I can almost taste your scent in the air.”

Diamond shook her head. She didn’t want to believe that it could be true. “You're lying…”

“Fine, claim whatever you want.” Tirek kept fucking her, thrusting into her tight pussy harder and faster. “All I know is that this is getting easier.”

Diamond looked away in disgust. “Urgh!”

Tirek slid his hand up her left thigh, his thumb finding her clit and rubbing it in small circles.

Diamond growled in response. “Hands off!”

“Why? Afraid you might actually like it?” Tirek stepped up his speed, timing his clit rubbing with the rapid thrusts of his large cock into her pussy.

“Because I don’t want you touching me any more than you already are.”

Tirek pulled his cock out of Diamond’s pussy. “I'll touch you where I fucking want to touch you!” He dragged his thumb down from her clit to the tight ring of her anus.

“No!” Diamond screamed, but it was too late.

Tirek pushed his thumb hard and it quickly slid in all the way.

Diamond yelped. “No! Stop that!” she shouted in discomfort.

Tirek did not stop that. He pumped his thumb a few times, swirling it around before pulling it out, slightly smeared with brown. Diamond shuddered.

Tirek walked his fingers up her bare stomach, chest, and neck. Diamond flinched. He pushed her jaw apart, sticking his thumb into her mouth and swirling it around her tongue. “You like that, slut?”

Diamond answered by biting his thumb.

“Ow!” Tirek withdrew his hand, shaking it in pain. “That fucking hurt, bitch!” He slapped her across the face.

“So did that, bitch,” she answered defiantly.

“You like pain? How's this?” Tirek punched her in the stomach, knocking the wind out of her. Diamond gasped for air. “You've had my thumb in there? How about my cock?” He lined up the head of his cock with her butt hole. “It's a bit bigger than my thumb.”

Diamond shook her head.

“Pussy or ass, Diamond? Pussy or ass?”

“Go fuck yourself!” she responded.

“I'd rather fuck you,” Tirek chuckled. “Which is it to be?”

“I'd rather you not.”

Tirek sighed. “You see, this is why you don't do well in class. You were asked a simple question… pussy or ass, Diamond?” Tirek prodded his cock against her anal ring slightly.

Diamond sighed. “This has nothing to do with school!”

“Come on… you don’t really want it in your ass, do you? Beg me to fuck you in the pussy.” Tirek grinned. He really wanted to hear those words.

Diamond was terrified of how much it would hurt. She wanted the creep away from her, but having him fuck her pussy again seemed the least worst option. Yet she couldn’t bring herself to give him the satisfaction of hearing her beg to be fucked. Something inside her stopped her from saying the words.

Tirek shrugged. “Ass it is then.” Diamond pouted, but didn’t verbally object. Tirek pushed hard against her ring, feeling it eventually give way, his cock sliding all the way into her butt. Diamond gritted her teeth, not wanting to give him the satisfaction of a scream. Gripping her thighs, Tirek started fucking her quickly. “This is nice,” he grunted. “Tight. Feels much better than your pussy did.”

Diamond bit her lip and said nothing. It hurt like hell, but she knew it was her own stubborn fault. She hadn’t told him to fuck her in the pussy, and this was the price she was paying.

Tirek thrust harder and harder, driving his cock deep into her bowels, and grunting between thrusts. Diamond squeaked.

Her teacher, roughly grasped at her bare breasts while he fucked her ass. Though he didn’t handle them how she liked them to be handled, Diamond figured that it at least distracted her a little from the pain in her ass, which, well, didn’t feel as painful now — more a severe discomfort.

Tirek made a few more quick thrusts before groaning, shuddering, and slowing down. Diamond felt her bowels get filled with warm liquid as Tirek sighed loudly. “You can be pretty good at this when you want to, you know, Diamond?”

“I'm literally doing nothing here.”

Tirek pulled out of her butt. “That's all a cum-slut like you needs to do. Just take it like a good little girl.” He walked back around to the other side of the table. He wiped his cock on her hair, smearing her purple locks with cum and worse.

“Gross…” Diamond muttered. She’d definitely be needing a shower when she got home.

Tirek bent down, pulling up his trousers and fastening the button. He untied the belt and loosened the loop from around Diamond’s wrists. While he fastened his belt, she rolled off the table and slumped onto the floor.

“You didn't exactly make that easy, you know?” Tirek walked around, gathering up her clothes. “You want these back?”

“Obviously.”

“Well” — he gestured around the room — “tidy up those chairs and desks. They're everywhere. You've made a complete mess with them.”

Diamond lay on the floor, feeling close to broken, but still mustered up a bit of defiance. “No, you did.”

Tirek kicked her in the side again. “Get the fuck up, and tidy the fucking desks!”

Diamond winced. “No. I’m tired.”

Tirek bent over her. “Yeah, I can get a bit sleepy after sex too. You just gotta push past it.” He dragged her up by her hair.

Diamond yelped. “Okay, okay!” She sighed and started dragging the displaced desks back into their proper places.

Tirek pointed to a desk which had a puddle of brownish cum on it.

The desk where he… Diamond shuddered just thinking about it.

“Lick it up,” her teacher commanded.

Diamond shook her head. “Oh, hell no!”

“You wanna go out there without your clothes?” He shook the handful of clothes at her. “Have everyone see what kind of whore you are? If you want your clothes back, you will lick… it… up.”

“Make me,” Diamond said defiantly.

“Sure.” Tirek dropped the clothes on the desk behind him, striding up to Diamond Tiara. He grabbed the back of her neck and slammed her face into the dirty desk. Blood leaked out of her nose, mixing with the dirty cum.

“Ow! I didn’t mean quite so roughly!”

Tirek dragged her face across the desk so that her mouth was near the cum. “Now lick it up.”

Diamond sighed and lapped up the mixture.

“Good girl.” Tirek let go of her neck and walked back to fetch her clothes. “Catch!” He tossed Diamond her bra which she put on with shaky hands.

“Th–thank you,” Diamond said submissively.

He threw her shirt over to her which she slipped on and began to button up. “Th–thanks.”

“Thanks, what?”

Diamond meekly looked at the floor. “Thank you, sir.”

Tirek stuffed her panties into his jacket pocket and tossed over her skirt.

Diamond glared at him. “Give them.”

Tirek looked at her blankly.

“Give them to me please, sir,” she tried.

Tirek chuckled. “You really think that out of all your whiny demands this afternoon, that’s the one I’m going to listen to?”

“It’s not like you’ve listened to any of them.”

“Precisely,” Tirek chuckled. “Now put your whore skirt on, and get yourself out of my sight. You disgust me.”

“I could say the same about you.”

Tirek chuckled. “Still haven’t lost that attitude, eh? Like I care anyway.”

Diamond stepped into her skirt and pulled it up before making a grab for his pocket. Tirek pulled away quickly. Diamond whined and pouted.

Tirek got the key out of his other pocket, and opened the door, passing Diamond her backpack. “Now get out of here.”

Diamond stomped on his foot and rushed out of the room and down the corridor.

Tirek barely felt the impact in his big leather boots. He chuckled and blew her a kiss. “Same time tomorrow, sweetie?”

Diamond stopped running and turned back to face the man. “You’re my sub all week, aren’t you?”

Tirek nodded. “Yup.”

“Well, shit.”

Author's Note

The author of this story does not condone Mr Tirek's behaviour. Rape is bad. Besides which, school staff should maintain a professional distance from students.

Also, I seriously, seriously adore Diamond Tiara. Even before Crusaders of the Lost Mark, I adored her. She and Sweetie Belle are tied for best filly, as far as I'm concerned. So don't tell me off for Diamond-hating, because I don't.
