The unruly students knew they ruled the college classroom. While split up among various cliques, all of them were united in their disdain for the lecture they would soon be forced to sit through. Even the studious nerds found it hard to take Miss Carlyle seriously as the timid old woman would uncertainly mumble her way through lessons and meekly ask the students to do their assigned readings. By the time winter break rolled around there was only one student still aiming to get an A in the joke of a class.
    Now the students were fresh from their vacation and bitter about having to return to school. They sat on top of their desks and openly ate food. A quartet of girls in the back were smoking and a water bottle filled with vodka was being passed around freely, as though the students were determined to break as many rules as possible.
    “So how do you think Miss Carlyle spent her winter break?”
    “Probably curled up with a dusty old book and a hundred cats.”
    “I know, right? She must be one of those crazy cat ladies.”
    “Nah, I bet even cats don’t like her.”
    The college girls laughed uproariously, even as they heard the door to the classroom opening. There was no need to hide their open disdain from Miss Carlyle. They had the poor old woman so beaten down that she didn’t even complain anymore.
    Rachel was the first to notice their teacher and immediately did a double take, wondering if Miss Carlyle had a younger sister. Her confusion was justified, since the sixty year old teacher’s gray hair had become a rich wave of dark locks, with a few attractive streaks of silver shining through. It wasn’t just a dye job, either, as Miss Carlyle’s wrinkles had entirely vanished, leaving her with the face of a forty year old supermodel. Gone was her frumpy old suit jacket and long dress; now she wore a stylish black coat over a blouse with a plunging neckline, which promised a surprisingly tempting expanse of cleavage. And her bare legs were left entirely on display as Miss Carlyle completed her outfit with a tiny black skirt that was hardly professional, but entirely tempting.
    Beyond the physical transformation of their teacher, who had impossibly managed to shed twenty years over break, there was also the new attitude with which she carried herself. Miss Carlyle walked in with an actual strut, hips swaying side to side as she threw back her rejuvenated long hair. Her green eyes glinted with newfound menace as she surveyed her trouble-making students. Her stark red lips frowned dangerously. 
    As Miss Carlyle’s intense gaze washed over Rachel she felt a shiver in her very soul. It was the fear of a rabbit seeing a wolf emerging from the shadows. But even stranger was a physical attraction that overtook the college girl. A sensual pull towards the teacher from the deepest edges of Rachel’s soul.
    “Holy shit,” Rachel muttered in awe. “Miss Carlyle’s hot.”
    Everyone burst into a deep laugh at that, as such a statement could only be the most absurd of jokes. Then one by one they turned and saw the new Miss Carlyle for themselves, jaws dropping at the radiant older woman. As everyone discovered the change in their teacher, Rachel was able to observe the change in the other students. Faces turning red, lower lips being bitten, clenching thighs and shudders of delight. They all felt it too. An instant, deep horniness for Miss Carlyle.
    What the hell was happening to them?
    For her part Miss Carlyle appeared content to stand at the center of the room, hands on her hips and leaving her new beauty on display. A single hand rose in the classroom. It was Penelope, the only student actually sitting in her seat with her notes out. She was also the only one in the whole class who had gotten an A on the mid-term.
    “M-Miss Carlyle?” Penelope said the name as a question, and Rachel couldn’t blame her.
    But sure enough this smoking hot woman who looked like Miss Carlyle’s daughter turned to Penelope and flashed a perfect grin. “What is it, Penelope?”
    The lonely nerd gulped as she struggled with how to word the question that was on everyone’s minds. How had she done this to herself? How had she become younger and drop dead sexy? As Penelope fumbled in her seat, Rachel decided that she was the only one able to get to the bottom of things.
    So the troublemaker shouted, “What the fuck happened to you?”
    Those green eyes snapped to Rachel. An unbearable pressure crashed over the young girl, making her tremble in fear. Miss Carlyle scowled at her and said, “Raise your hand first if you wish to speak.”
    It was a classroom rule that mousy Miss Carlyle had reminded Rachel of dozens of times back when the fall semester began. By October the teacher finally surrendered, saying nothing every time Rachel shouted something or loudly joked in class with the other girls. 
    Which is to say that Rachel should have been immune to the rule as always, but now it was different. Rachel felt a green sense of dread overwhelming her senses at Miss Carlyle’s scolding. So, with the whole class watching in shock, Rachel found herself shaking and replying, “Y-yes, Miss Carlyle. I’m sorry, Miss Carlyle.”
    “Good girl.”
    Rachel shuddered as the dread inside of her instantly transmuted into pleasure. An overwhelming joy that she could make her teacher happy. It was such a bewildering change that Rachel barely managed to hold back a moan.
    “Now there will be some changes in this classroom,” Miss Carlyle announced, ignoring Rachel’s question. She let her intense green gaze travel across each and every one of her students. “Sit in your seats.”
    It was a cacophony as two dozen students threw themselves off their desks, scattering papers and snacks in their mad dash to get into their chairs. More than a few girls fell to the floor in their haste. The only ones who didn’t move were Penelope, the nerdy girl already in her seat, and Rachel, who was too astonished at how horny she was for her teacher to respond to the command. She sat there dripping wet and wondering how she could possibly be turned on by a woman she’d regularly mocked as an old spinster.
    Then Rachel found herself locking eyes with Miss Carlyle again. “Sit in your seat, Rachel. Sit like a good girl.”
    This time Rachel groaned as she fell backwards, slipping off the desk and landing roughly down into her chair. She quickly righted herself, snapping her head up to pay attention to her teacher. Rachel had never cared about being a good student before, but now she needed desperately to sit in her seat properly for her teacher. To be a good girl. Why were those words pulsing in her head?
    Miss Carlyle surveyed the class and nodded approvingly. “Much better. Now, I’m sure many of you are wondering the same question that Rachel so boldly asked me. What the fuck happened to me?” Miss Carlyle spun around and made her way over to her desk, letting her ass sway with all the grace of a model on the catwalk. Rachel bit her lip and stared hungrily at that perfect ass. If she had looked around the room Rachel would have discovered she wasn’t the only college student lusting after Miss Carlyle.
    “I did consider coming up with a lie to explain my appearance. Tell you all that I received some surgery or beauty regimen. But then I thought, why hide the truth? I’ve spent my whole life hiding, and now I can finally be who I always wished I could be.” 
    Miss Carlyle turned to face the class. She rested her hands against the desk behind her, thrusting out her breasts towards her students. Rachel was gazing so longingly at her teacher’s tits that she almost didn’t notice the sharp fangs in Miss Carlyle’s smile.
    “The truth is that I’m a vampire now. I was bitten by a lovely woman over winter break, and now I have all the powers that come with being a vampire. Eternal youth. Unnatural appeal to make all desire me. And a hypnotic gaze to impose my will over others.”
    The students exchanged nervous glances, daring each other to believe their crazy teacher. The funny thing was that Rachel did believe it. After all, Miss Carlyle did look twenty years younger. And there was no doubt that Rachel felt unnaturally horny for her. But most of all, Rachel knew she spoke the truth about her hypnotic gaze. Because Rachel’s brain was still ringing with the desire to be a good girl, as if Miss Carlyle had branded the two words into her brain.
    “I must also drink blood, of course. Beauty like this doesn’t come free. So I’ll be drinking from you students over the rest of this semester.”
    As horny as she was, and as much of a good girl as she wanted to be, Rachel wasn’t about to let her teacher drink her blood. Though it was troubling how tempted she felt over it. Several girls got to their feet, grabbing their bags to flee or pulling out their phones, not that Rachel knew who you could call for help over a situation like this.
    “Sit!” Miss Carlyle commanded. Every girl instantly dropped back into their seats. “Phones away, too. No phones out during class.”
    Rachel heard the words and knew it would have been impossible to try and reach for her phone if she wanted to.
    “Not to worry, students. I won’t be drinking from all of you. Only those who deserve it based on your test scores.”
    And that was the moment Rachel knew she was doomed. Her friends threw her sympathetic looks. It was no secret that Rachel had the worst scores in the class, because she’d proudly shown off her abysmal test scores to everyone as she failed on purpose. Well, she was failing already, but had then taken it as a challenge to make her grade as low as possible. With her parent’s connections Rachel knew she’d be safe no matter what, and at least if she failed as a joke no one would make fun of her for failing anyway.
    Rachel sat gripping her chair with white knuckles. Would it hurt when Miss Carlyle bit her neck? How much blood did vampires drink anyway? Would Miss Carlyle call her a good girl?
    That last thought appeared on its own, and Rachel found she couldn’t banish the desire. She wanted to be a good girl.
    Which is why Rachel was shocked and disappointed when Miss Carlyle called out the name, “Penelope.”
    The nerdy girl nearly slipped out of her chair as she flailed. “Me?”
    “That’s right, dear. You’re the only one who got an A on the midterm. So you’ll be the one I drink from first. Come here.”
    As terrified as Penelope looked, her body rose up on its own accord and began to walk its way toward the teacher. Penelope clearly had no control as she kept shaking her head wildly. “B-but I’ve been so good. I don’t make jokes or say mean things like the other girls. Why am I being punished? It’s not fair!”
    Suddenly Miss Carlyle crossed the distance between them in the blink of an eye. She wrapped a hand behind Penelope’s head and dragged a finger along her chin. Rachel felt a tremor of jealousy hit her as Penelope went limp in Miss Carlyle’s grip.
    “Do you really think being bitten by me is a punishment?” 
    Penelope’s glasses reflected the glowing green light from Miss Carlyle’s eyes. The nerd shuddered and moaned as Miss Carlyle dipped her lower, as if they were lovers dancing. “N-no, Miss Carlyle.”
    “Being bitten by me will be the greatest pleasure you could ever know.”
    “Yes, Miss Carlyle,” Penelope repeated dreamily. “Being bitten by you will be the greatest pleasure I could ever know.”
    Rachel was leaning over her desk, struggling to get a closer look without lifting her butt off the chair. She had to stay seated, like Miss Carlyle had said. The other students in class were craning their necks to watch too. All of them wore the same hungry jealousy on their faces that Rachel felt.
    Suddenly Miss Carlyle whipped her head to glare at the class. “You will all read up to chapter 15. I want all of you to catch up on your reading before you leave here.”
    “Yes, Miss Carlyle,” the class chanted. The words left Rachel’s mouth automatically, but she didn’t mind repeating what her teacher told her like a good girl. What she did resent, though, was the overwhelming urge to look away from the tempting scene of Miss Carlyle ravishing Penelope with a deep kiss. Instead of watching the erotic scene, Rachel found herself twisting around in her seat to pull her textbook from her bag. She opened the book to page one and began to read, biting her lip in frustration as she found herself unable to take her eyes off the page.
    “Oh! Ah! Miss Carlyle! Miss Caaarlyyyle…” Penelope’s moans sang through the classroom, leaving Rachel forced to only imagine how wonderful the vampire teacher’s bite must be. It sounded like it would be amazing. Like being bitten by Miss Carlyle would be the greatest pleasure they could ever know.
    “This will be the new system our class works by,” Miss Carlyle announced, as Penelope gurgled with pleasure on the floor. “You will not tell anyone about what happens in our classroom.
    “Yes, Miss Carlyle,” Rachel and the other students replied.
    “I will only be drinking blood from those of you who manage to earn an A on tests. Those of you who don’t earn an A will get to sit there and make up your work, while I reward all my good students who please me.”
    “Yes, Miss Carlyle!” Everyone spoke the words enthusiastically, returning to their books eager to read. All except Rachel, who mumbled the words bitterly.
    It wasn’t fair. Rachel squirmed in her seat, dripping wet and horny out of her mind, but unable to do anything about it. All she could do was curse her stupid past self for not doing any homework or paying attention in class, because it left her starting so far behind everyone else. How could she possibly earn an A? She barely understood the material as it was.
    Rachel could already picture it. The classroom transformed into an orgy, all the other students naked and laid out on the floor in blissed out trances. Miss Carlyle sensually biting their necks one by one, drinking from them and giving mind blowing pleasure in return. Using the students as her playthings in any way she wanted. 
    All while Rachel was left alone at her desk, just a stupid girl unable to do anything right.
    “Rachel.”
    Hearing her name in that wonderful voice made Rachel’s breath catch in her throat. She looked up in surprise to find Miss Carlyle standing over her. Her blouse was open to reveal the most beautiful tits that she had ever seen. All Rachel wanted to do was lean forward and suck on them.
    “Come here,” her teacher commanded, and suddenly Rachel lunged across the desk to plant her face between Miss Carlyle’s tits. She kissed at the perfect cleavage and moaned with abandon. All while Miss Carlyle stroked her head, cooing affectionately at the poor girl.
    “It’s okay, dear. I can sense your frustration.”
    “I can’t do it,” Rachel whined. “I’m not smart enough. You’ll never bite me and drink my blood.” She had taken it for granted that she’d never want a vampire to bite her, but then she’d never imagined that it would be someone as captivating as Miss Carlyle drinking her blood. Now it was all she wanted, and she’d never get it.
    “None of that, Rachel. You are my student, and I am your teacher. I won’t let you fail.”
    Rachel pried herself away from her teacher’s tits, tears in her eyes. “You won’t?”
    Those hypnotic green eyes bored into her with love and determination. “Never. I’ve always been here to help you. But I need you to be ready to listen to me.”
    “Yes,” Rachel moaned, throwing aside any shred of ego or pride she’d held onto. “Yes, Miss Carlyle. Please help me.”
    “Put aside all those fears and doubts. Trust yourself. You can do this.”
    The vampire’s words twisted in her mind, calming her better than any drug. A lazy smile crossed Rachel’s face. “Yes, Miss Carlyle.”
    Miss Carlyle gave her a fanged smile, then leaned forward and bent her head toward the side of Rachel’s neck. She tensed herself, hoping to feel the sweet pain of her teacher’s fangs. Instead, Miss Carlyle only kissed her neck tenderly. “I believe in you.”
    Without the vampires gaze locked onto her, the words didn’t come with the same magic power as her other commands. But Rachel found herself believing it completely. Her hot, sexy vampire teacher believed in her, even after all the trouble she’d caused all semester.
    Rachel collapsed back into her seat, shaking with relief and happiness. She gave her teacher a grateful look, then picked up her book and got to work. She could do this. She would do this. Anything to make Miss Carlyle proud.
    A week later Rachel was sitting bolt upright at her desk, dressed smartly and properly. The entire class had changed, with all the students rigorously doing their best to become model students. Their friends had laughed at them or questioned them, but none of them knew the truth.
    Or recognized the faint scars of twin dots appearing on their necks.
    “You’ve all improved so wonderfully,” Miss Carlyle announced, seated upon her desk like it was a throne. She was in sheer black lingerie, and had begun to routinely remove her clothes as soon as class began. Penelope was naked and kneeling before her, busy eating out the teacher before the whole class. Everyone was jealous of the teacher’s pet and wished to be in her place.
    “Now come up one by one to receive your test scores.”
    Rachel’s whole body was brimming with excitement. She’d studied so hard and worked her ass off. She’d even gone begging to Penelope to tutor her, although at least a dozen of her classmates had the same idea. While she was nothing but her teacher’s plaything in class, outside the classroom Penelope had begun to dominate the others in return for help on their studies. Rachel would have never guessed that the mousy nerd had it in her. Or that she’d enjoy Penelope spanking her and riding her face so much.
    Still, as the students filed up one by one, Rachel couldn’t help but wonder if she’d done enough. It seemed as though everyone was earning an A, as Miss Carlyle handed them back their test and then gazed into their eyes, stroking their neck hungrily as if claiming them. She’d be drinking from all of them for the week, and likely the rest of the semester if they kept their grades up.
    Finally it was Rachel standing before Miss Carlyle, trembling like a leaf in Autumn. Her test was handed to her, and Rachel could have cried when she saw her grade written in blood red marker.
    B.
    “I’m so sorry,” Rachel whispered, as the familiar crushing weight of failure settled on her. But suddenly there was a firm grip on her chin forcing Rachel’s head up, until she was staring into Miss Carlyle’s glowing green eyes.
    “This is not a failure, Rachel.
    “But- but I didn’t get an A.”
    “You went from the worst test scores I’ve ever seen to a B in one week. Do you understand how remarkable that is?”
    Rachel whined, losing herself in Miss Carlyle’s eyes.
    “I can see how hard you worked on this. You’re beginning to really understand the material. I’m so proud of the progress you’ve made. I’m sure you’re close to getting an A soon.”
    “You’re really proud of me?”
    The vampire smiled warmly. “So proud of you.” Then Miss Carlyle leaned in and kissed her deeply. Rachel could have never imagined that she’d be orgasming from kissing her sixty year old teacher in front of everyone, but then she supposed that must be vampiric powers at work. Or perhaps it was because she was so desperately grateful to finally be seen and acknowledged like this. For a sexy, older woman to recognize her hard work and encourage her. It filled Rachel with submissive joy. She could have pledged her whole life away to serving and pleasing Miss Carlyle. Perhaps she might, if the vampire was in the mood for keeping any of her toys.
    “So… do I get bitten?” Rachel couldn’t help but ask eagerly.
    Miss Carlyle stroked a sharp nail along the side of her neck. She left a single cut, a promise of pain and exquisite pleasure to come. “Not yet. You still have to earn it, my dear.” As Rachel watched, Miss Carlyle brought her finger up to her mouth and licked the drop of Rachel’s blood off of her nail. Miss Carlyle’s eyes rolled back in delight. “Mhm, you taste delicious. Hurry up and earn that A, Rachel. I can’t wait to taste more.”
    “Y-yes Miss Carlyle!”
    Rachel turned and saw the whole class staring at her, knowing what a horny and desperate mess she was. But all she saw were her friends smiling at her proudly or giving her a thumbs up. Even Penelope, naked and kneeling beside Miss Carlyle’s desk like a good teacher’s pet, gave her an encouraging smile.
    Rachel floated back to her desk happily. She could do this. She cracked open her textbook, now littered with multi-colored post it notes and highlighted sections she’d reviewed. Rachel was determined to study hard and make her teacher proud. She’d become a submissive blood bag to slake her sexy vampire teacher’s thirst. Rachel couldn’t imagine a better motivation to lift her grades than that.
    As she hit the books, the classroom filled with the lustful moans of women being bitten and drained.
