The semester had been a slow-motion disaster for Ana, each week bringing new absences, missed assignments, and pathetic excuses delivered with a practiced pout and a strategic bend at the waist. At twenty, she had perfected the art of transactional femininity—flashing doe eyes, letting her oversized breasts strain against thin fabric, leaning close enough for professors to smell her perfume. It had worked for three years. It had worked with everyone except Mr. Howard.

She had noticed him watching her. The way his eyes tracked her when she entered the classroom, how they lingered on her chest when she leaned over to pick up her bag. But unlike the other professors, he never softened when she turned on the charm. Never offered extensions when she cried. Never accepted her invitations to "discuss her grade" over coffee.

Ana was twenty years old, 5'3" and 110 pounds, with a body that seemed designed to draw male attention. Her breasts were disproportionately large for her small frame—heavy, soft mounds with puffy areolas the size of silver dollars that crinkled when she was cold or aroused. She had learned early that these assets could open doors, excuse tardiness, and transform C's into B's with minimal effort. She wasn't promiscuous—she'd only slept with three men, including her current boyfriend—but she was an expert at the tease, at the promise, at the strategic display of cleavage that left men imagining what lay beneath.

Mr. Howard was different. The 35-year-old professor watched her with the patience of a predator studying wounded prey. He had brown hair and eyes, a thin build that seemed unremarkable, but there was something in his gaze that made Ana nervous in ways she couldn't articulate. When she stumbled into his Monday afternoon lecture thirty minutes late, reeking of alcohol and stale perfume from a weekend bender, wearing a white blouse that she'd deliberately left three buttons open on, he finally reached his limit.

"Ana. My office. Now." His voice carried no inflection, but the classroom fell silent. The other students exchanged glances, sensing something shift in the atmosphere.

She followed him down the hallway, her heels clicking on the tile, her head pounding from her hangover. She was too foggy to notice that he paused at his door to flip the deadbolt after they entered. The office was small, windowless, lined with bookshelves that smelled of old paper and dust. A solid oak desk dominated the center of the room, its surface cluttered with papers and a heavy brass lamp. Ana stood near the door, shifting her weight, her arms crossed beneath her breasts in a pose she'd practiced to maximize cleavage display.

"Close the door," he said, not looking at her. "And lock it."

"It's already—"

"Lock it."

Something in his tone made her obey. The deadbolt clicked with a finality that made her stomach flutter. When she turned back, he was standing directly behind her, close enough that she could smell his cologne—something dark and musky. She took a step back and bumped into the door.

"Please, Mr. Howard," she started, her voice taking on the breathy quality she used when manipulating men. "I know I've been struggling, but I can do better. I just need a little flexibility—"

"Flexibility?" He laughed, a dry, humorless sound. "You've had flexibility all semester. You've had extensions, makeup opportunities, extra credit offers. You've had every chance to succeed through actual effort." He moved closer, crowding her against the door. "But that's not what you want, is it? You want to continue using what you have between your legs to get what you haven't earned."

Ana's mouth opened to protest, but his hand shot out and gripped her jaw, squeezing hard enough to make her gasp. His fingers dug into her soft flesh, forcing her to look up at him.

"Those puffy little lips," he murmured, his thumb pressing against her mouth. "This body you've been parading around. These tits." His other hand moved to her chest, not gently—he grabbed her breast through her blouse, kneading it roughly, his fingers finding her nipple through the fabric and pinching hard. Ana squeaked, trying to pull away, but he had her pinned. "You've been teasing me with these all semester. Letting them bounce when you walk. Leaning over my desk so I can see down your shirt. Did you think I didn't notice? Did you think I was immune?"

"Please," she whimpered, genuine fear beginning to replace her practiced seduction. "I didn't mean—"

"You didn't mean to be a stupid little cocktease?" He released her breast only to grab the front of her blouse. With one violent yank, he ripped it open. Buttons scattered across the floor like teeth. Ana gasped, crossing her arms over her chest, but he knocked them away. "Don't cover yourself. Not after all the effort you've put into showing off."

He reached behind her and unclasped her bra with practiced efficiency. When it fell away, her breasts spilled out—heavy, pale, with large areolas that were indeed puffy and prominent, the nipples already hardening in the cool air of the office. They were oversized for her small frame, gravity-defying mounds of soft flesh that jutted out invitingly. Mr. Howard stared at them with naked hunger mixed with contempt.

"Look at these," he said, cupping them roughly, lifting their weight. "These are what you've been using to manipulate men. These puffy nipples, these heavy tits. You thought they were weapons. Tools. Let me show you what they really are."

He leaned down and took her left nipple into his mouth, not gently—he bit down, hard, his teeth sinking into the tender flesh around the areola. Ana screamed, her hands flying to his head to push him away, but he grabbed her wrists and pinned them against the door above her head. He continued to assault her breast with his mouth, sucking hard enough to leave bruises, biting until she was sobbing, switching between them until both nipples were swollen, red, and throbbing with pain.

"Stop," she cried, tears streaming down her face. "Please, it hurts—"

"Good," he said, pulling back to admire his work. Her breasts were marked with red bite marks, the puffy areolas swollen and sensitive-looking. "That's the point. You're going to learn that your body isn't a tool for manipulation anymore. It's a vessel for punishment."

He released her wrists and grabbed her by the throat again, walking her backward until the backs of her legs hit his desk. With a shove, he bent her over it, her face pressed against the cool wood, her breasts squashed painfully beneath her. She heard him moving behind her, the sound of his belt unbuckling, and she began to thrash in earnest.

"No! Please, don't! I'll do the work, I'll—"

"Shut up." He grabbed her jeans and yanked them down, taking her panties with them. The air hit her exposed sex, and Ana realized with horror that she was wet—her body responding traitorously to the adrenaline and fear. "Look at that," he said, his fingers probing her roughly, shoving inside without warning. Ana cried out at the intrusion, his fingers thick and invasive, curling inside her with no gentleness. "The stupid slut is soaked. You probably dream about this, don't you? Getting forced down and used."

He removed his fingers and she heard the wet sound of him unzipping his trousers. When the head of his cock pressed against her entrance, it felt enormous—hot and thick and impossibly large. He didn't prepare her. He didn't wait. He drove forward in one brutal thrust, forcing his way into her tight channel with a grunt of satisfaction.

The pain was immediate and overwhelming. Ana shrieked, her hands scrabbling at the desk, nails scratching uselessly at the wood. He was thick—thicker than her boyfriend, thicker than anyone she'd been with—and he was splitting her open. Her body resisted, clamping down around him, which only made him groan with pleasure as he forced himself deeper.

"Fuck, you're tight," he growled, gripping her hips hard enough to leave bruises. "Probably because you're actually paying attention for once, aren't you? Finally realizing you're not special. Just another dumb college girl who needs to be fucked stupid to understand her place."

He pulled back and slammed in again, harder. Ana's scream dissolved into broken sobs. Each thrust felt like being torn apart, her pussy burning around his girth, the friction intense and painful. The desk creaked beneath them, its legs scraping against the floor with every violent impact. He wasn't making love to her—he was punishing her, using her body as a vessel for his contempt.

When he finally pulled out, Ana lay there gasping, her pussy throbbing with a dull, aching pain. She thought it was over. She was wrong.

"Turn over," he commanded. "On your knees."

Too weak to resist, Ana slid off the desk and onto the floor, her legs trembling. He grabbed her hair and forced her to face him. His cock glistened with her arousal and his precum, thick and veined and angry-looking.

"You want to know how you're going to pass this class?" he asked, his voice conversational despite the violence of moments before. "I'm going to offer you a sliding scale of grade improvements. A menu of degradation, if you will."

He pressed the head of his cock against her lips. "Open."

When she hesitated, he slapped her face—not hard enough to truly injure, but enough to shock her into compliance. Her mouth opened, and he pushed inside, his taste salty and musky, filling her mouth with his girth. Ana gagged immediately, her eyes watering, but he held her head steady and began to thrust, fucking her mouth with the same brutality he'd used on her pussy.

"Here's the deal," he said, his voice strained with pleasure as he used her throat. "A D-minus if you take my cock in your mouth whenever I demand it. Just this. Being my little oral slut, my cum dumpster for your grades."

He pulled out, letting her gasp for air, strings of saliva connecting her lips to his cock. "A D if you let me fuck that tight pussy too. Both holes, whenever I want. You come in here, you spread your legs, you take it until I finish."

Ana sobbed, shaking her head, but he slapped her face again.

"A C if you let me cum in you daily until the semester ends," he continued, his eyes dark with cruelty. "Wherever I want. Your mouth, your cunt, your ass—I own your body for the next three months. You wear my cum inside you, you taste it, you feel it leaking out of you during your other classes. Every day, Ana. Every single day."

He grabbed her by the hair and dragged her back to the desk, bending her over again. "A B if you let me stretch this little pussy properly. Brutal stretching. Fisting. Toys. Making you loose and ruined, teaching you that your cunt is just a hole to be used, not some precious treasure. By the end of the semester, you'll be so stretched out you'll barely feel a normal man."

He thrust into her again, making her scream, pounding her sore, abused pussy with renewed violence. "And an A," he grunted, his thrusts becoming erratic, "if you become my complete sex toy. Limitless use. Pain for every part of your body this slut form holds. Nipple biting until they bleed. Clamps. Whips. Caning your ass until you can't sit down. Using every hole, every day, in every way I can imagine. Total ownership. Total degradation. You become nothing but a set of holes for my pleasure, and in exchange, you get your precious A."

He reached around and grabbed her breasts again, his fingers finding her sore, bitten nipples and twisting them viciously. Ana shrieked, her body convulsing with pain, but he didn't stop. He pounded into her, his hips slamming against her ass with wet, obscene sounds, his cock battering her cervix with every thrust.

"What's it going to be, Ana?" he demanded. "Are you going to be a good little whore and earn your grades the only way you're capable of? Or are you going to fail and explain to your parents why you're dropping out?"

He pulled out suddenly and flipped her over, pushing her back onto the desk. Her legs dangled off the edge, her pussy exposed and red and swollen. He grabbed her knees and forced her legs apart, staring down at her abused sex with a predator's hunger.

"Look at this," he said, his fingers probing her entrance, shoving three fingers inside her roughly, stretching her painfully. "Already getting loose. Already learning your place. By the end of the semester, this cunt is going to be ruined. Gaping. Useless for anything but my cock."

He positioned himself at her entrance again and drove in, making her arch off the desk in pain. He leaned over her, his weight crushing her, his mouth finding her neck and biting hard enough to leave marks. His hands returned to her breasts, squeezing and mauling, his fingers pinching and twisting her puffy areolas until she was crying continuously, a steady stream of tears running down her temples into her hair.

"Please," she gasped, her voice broken. "It hurts too much—"

"Good," he grunted, his thrusts becoming savage, mechanical. "That's the point. You're going to hurt every day. You're going to ache. You're going to walk funny. You're going to sit in my class with my cum dripping out of you, your nipples sore from my teeth, your pussy throbbing from my cock, and you're going to remember that you earned this. That you chose this. That you're nothing but a stupid, lazy slut who has to get raped by her professor to pass a class."

He reached down between them and found her clit, rubbing it roughly, painfully, his fingers digging in. Ana's body betrayed her again—a jolt of unwanted pleasure shot through her, making her gasp despite the pain. He laughed, feeling her response.

"Oh, you like that? The stupid slut likes being hurt. Probably why you dress like a whore—deep down, you know you deserve this. You want to be used. You want to be broken."

He increased his pace, pounding into her with a fury that made the desk scrape across the floor. Ana's sobs became desperate, broken sounds as her body responded traitorously to the stimulation. She could feel her orgasm building, a humiliating tide she couldn't stop, rising with every brutal impact against her cervix, every vicious twist of her nipples.

"No," she whimpered, hating herself. "Please, don't make me—"

"Come on, bitch," he growled, his fingers working her clit mercilessly. "Come while I rape you. Show me what a pathetic whore you really are. Come on my cock while I ruin your pussy."

The words, the degradation, the relentless friction—it all crashed together. Ana's body convulsed, her muscles clamping down on him as she came with a scream that was half pleasure, half anguish. It wasn't a gentle release—it was violent, tearing through her like a storm, her pussy spasming around his invading cock, her back arching off the desk as she shook uncontrollably.

"Good girl," he mocked, his thrusts becoming erratic, savage. "Now take what you've earned."

He buried himself to the hilt and erupted inside her, pulsing hot and thick, filling her with his release. Ana felt every spurt, the humiliation complete as he emptied himself into her unprotected womb. For a long moment, he stayed there, his weight crushing her, his cock still twitching inside her abused body, his mouth latched onto her nipple, sucking hard as if he could draw milk from her.

When he finally pulled out, it was with a wet, obscene sound. He stepped back, leaving her sprawled across his desk, legs dangling, cum already dripping down her thighs onto the floor. Her puffy areolas were dark with bite marks and bruises, her nipples swollen and tender. Her pussy throbbed with a deep, aching pain that she knew would last for days.

"Welcome to the D club," he said, tucking himself back into his pants. "You took it in both holes today, so I'll give you a D. But tomorrow, you come back for your daily dose if you want to keep that grade. And Ana? Wear a skirt. No panties. I want easy access."

Ana lay there for a long moment, unable to move, her body throbbing with pain and the aftershocks of her unwanted orgasm. When she finally managed to stand, her legs trembling, she dressed in silence, avoiding his eyes. Her blouse was ruined, her bra destroyed, her jeans the only intact clothing she had. She could feel his cum leaking out of her, warm and humiliating, running down her legs.

She left without a word, walking across campus with her head down, feeling every eye on her, wondering if they could tell what had been done to her. Wondering if they could smell him on her skin, see the marks on her neck, notice the way she walked with a slight limp from the abuse between her legs.

---

Three days later, Ana stood in his office doorway, her acceptance letter to medical school clutched in her trembling hand. She had worked four years for this—late nights, student loans, the pressure of being the first in her family to graduate college. The letter specified a minimum 3.8 GPA. His class was the only thing standing between her and her future.

"I need an A," she said, her voice barely a whisper. "Not a B. Not a C. An A. I'll do whatever it takes."

Mr. Howard leaned back in his chair, a slow smile spreading across his face. "Close the door. Lock it. Then come here and undress completely."

When she hesitated, he raised an eyebrow. "You said whatever it takes. Prove it."

Ana's fingers shook as she unbuttoned her coat, letting it fall to the floor. She wore nothing underneath—he had instructed her yesterday to stop wearing undergarments entirely. Her breasts hung heavy, the puffy areolas still bearing the bruised bite marks from Monday. Her pussy was visible, red and slightly swollen from the daily use he'd been putting her through.

"Good," he said, rising from his chair. "You've been taking your daily training seriously. But an A requires something more. Something permanent. Something that will change you forever."

He walked to the cabinet in the corner of his office—the one she'd always assumed held grading rubrics and extra paper. When he opened it, Ana felt her stomach drop through the floor.

The dildos were monstrous. Not merely large—grotesque. The smallest one was thicker than her wrist, black and veined, with a flared base that looked wider than her closed fist. The next size up was the girth of a soda can, curved and ridged. But the largest—the one he pulled out with both hands—was thicker than a human fist, longer than a forearm from elbow to fingertips. It was a flesh-toned monster with a bulbous head the size of a grapefruit, the shaft covered in thick, aggressive ridges designed to scrape and stretch.

"For an A," he said, setting the massive toy on his desk with a heavy thud, "you need to be able to take this. All of it. To the base."

Ana shook her head, backing away. "That's impossible. It will tear me apart. It will—"

"It will stretch you," he interrupted, pulling out a long, industrial-sized bottle of lube—clear, viscous, enough to coat her entire body. "It will hurt. It will feel like you're being split open. But you will take it. Because you need that A for medical school, don't you? You need to be my perfect little A-student. My limitless sex toy."

He grabbed her arm and pulled her to the desk, bending her over it roughly. Her breasts pressed against the cool wood, her nipples aching as they made contact. She heard the cap of the lube bottle open, heard the wet, obscene sound of him pouring it directly onto her exposed sex.

"First," he said, his fingers probing her entrance, slick with lube, "we establish your baseline."

He shoved three fingers inside her immediately, making her gasp. Then four. His hand was large, his fingers thick, and he twisted them inside her, scissoring them apart, stretching her entrance painfully. Ana cried out, her hands gripping the edges of the desk, her knuckles white.

"Loose," he commented, adding his thumb, making his hand into a duck-bill shape. "But not loose enough. You've been taking my cock daily, so you're getting stretched, but this?" He pushed harder, his knuckles pressing against her entrance, threatening to pop inside. "This is just the beginning."

He worked his hand against her, pressing, retreating, adding more lube until it was dripping down her thighs, pooling on the floor beneath her. The pressure was intense, burning, her body resisting even as he forced it to yield. When his knuckles finally breached her entrance, Ana screamed into the desk, her back arching in agony as her pussy was forced to accommodate the widest part of his hand.

"That's it," he grunted, pushing deeper, his entire hand disappearing inside her up to the wrist. "Fuck, you're tight even like this. But we're going to fix that. We're going to ruin this cunt until it's useless for anything but massive insertions."

He fisted her slowly, twisting his hand, pumping it in and out with wet, squelching sounds. The pain was overwhelming—a deep, burning stretch that made her feel like she was being torn in half. Her pussy clenched helplessly around his invading hand, trying to expel the intrusion, which only made him groan with pleasure.

"Now," he said, his voice strained, "the training begins."

He pulled his hand out with a wet pop, leaving her gaping, her entrance twitching and swollen. Before she could recover, he grabbed the smallest of the massive dildos—the one merely the thickness of her wrist—and pressed it against her abused hole.

"No," she gasped. "Please, I'm too sore, I can't—"

"You can," he said, and shoved.

The dildo was unyielding, rigid silicone that forced her open wider than she'd ever been stretched. Ana's scream was raw, guttural, her body convulsing as he worked the massive toy into her inch by inch. It felt like a log being forced inside her, her tissues screaming in protest, her cervix being battered as he pushed deeper.

"Halfway," he observed, looking down at where her pussy was stretched obscenely around the black silicone. "You're doing well, slut. But we need to go deeper."

He grabbed the lube bottle and poured it directly onto the exposed portion of the dildo, letting it run down into her stretched hole. Then he pushed harder, his other hand pressing on her lower back, pinning her as he forced the toy deeper. Ana's vision blurred with tears, her screams becoming hoarse as the dildo pressed against her cervix, then—agonizingly—began to push past it, entering her deepest regions.

"Please," she sobbed. "It hurts, it hurts so much, please stop—"

"Nine inches," he said, ignoring her pleas. "You've got three more to go. Take it for your A, Ana. Take it like a good little medical student."

He pushed again, and the dildo sank to the base, the flared bottom pressing against her stretched, gaping entrance. Ana's mouth opened in a silent scream, her body shaking uncontrollably. She could feel the massive intrusion in her abdomen, pressing against her organs, filling her completely. It was agony—pure, burning, stretching agony that made her want to pass out.

"Good," he said, his voice thick with arousal. "Now you hold it. Ten minutes. If you push it out, we start over."

The ten minutes were an eternity. Ana lay there, sobbing, her pussy stretched around the massive toy, feeling every ridge, every vein, every millimeter of its obscene girth. When he finally pulled it out, she felt hollow, gaping, ruined. Her entrance didn't close—it stayed open, a dark pink circle of abused flesh that twitched helplessly.

"That's your training for today," he said, wiping the dildo with a cloth. "But an A requires more. An A requires constant stretching. Permanent modification."

He reached into the cabinet and pulled out something that made Ana's blood run cold—a set of metal dilators, graduated in size from large to horrifying. They were stainless steel, cold and heavy, with flared bases and smooth, unforgiving surfaces.

"These," he said, holding up the smallest one—still thicker than two of his fingers—"you will wear every day. All day. In your cunt. While you go to other classes. While you eat lunch. While you sit in the library studying. You will be constantly stretched, constantly reminded that your pussy belongs to me now. That it's being trained to take anything I want to put in it."

He coated the metal plug in lube and approached her. "Spread your legs wider."

Ana obeyed, trembling, her pussy still gaping from the dildo. He pressed the cold metal against her heated entrance and pushed. It slid in easier than the dildo, but the weight of it was different—heavy, pulling down on her insides, making her feel constantly full. When it seated inside her, the flared base pressing against her stretched entrance, she gasped at the sensation.

"You'll start with this one," he said, tapping the base of the plug, making it vibrate inside her. "Every three days, you come here and I replace it with the next size up. By the end of the month, you'll be wearing one thicker than my fist inside you constantly. Your pussy will be stretched, loose, ruined. You'll walk funny. You'll feel it with every step. And you'll thank me for it, because you'll be earning your A."

He pulled her off the desk and made her stand. The weight of the metal plug made her feel like she was going to split open. She could feel it shifting inside her with every movement, the cold steel warming slowly to her body temperature but never becoming comfortable.

"Now," he said, unzipping his pants, "for the final part of your A-grade training. Wedging."

He bent her over the desk again, her breasts hanging down, the metal plug still heavy in her cunt. He poured more lube onto her asshole, making her whimper with dread. When his finger pressed against her tight rear entrance, she tried to clench, but he slapped her ass hard.

"Relax, or this hurts more."

He worked his finger into her ass, then two, stretching her sphincter roughly. Ana groaned, her face pressed against the desk, tears still wet on her cheeks. When he pulled his fingers out, she felt something else pressing against her—the head of his cock, slick with lube.

"Double penetration," he said, his voice strained with arousal. "The metal in your cunt, my cock in your ass. This is what an A feels like, Ana. This is what limitless use means."

He pushed into her ass in one brutal thrust, making her scream as she was filled from both sides. The metal plug in her pussy made her ass even tighter, the pressure intense, the sensation of being completely full overwhelming. He began to fuck her ass roughly, his hips slamming against her, the metal plug shifting inside her with every thrust, creating a sensation of being fucked in both holes simultaneously.

"Whatever I want," he grunted, pounding her. "Whenever I want. That's what an A means. I can wedge whatever I want in your holes. My cock, these plugs, the massive dildos—eventually, you'll take them all. You'll be so stretched out, so ruined, that you'll be able to take the largest dildo to the base without crying. Your pussy will be a loose, gaping hole, perfect for my use, useless for any normal man. And you'll wear that metal stretcher every day, feeling it inside you, knowing that you're being permanently modified for my pleasure."

He reached around and grabbed her breasts, his fingers finding her puffy, bruised areolas and pinching viciously. "Your nipples will be bitten daily. Your ass will be fucked raw. Your pussy will be stretched beyond recognition. And you'll take it all, because you need that A. Because you're a desperate little slut who will destroy her own body for a grade."

His thrusts became savage, his cock battering her ass, the metal plug shifting painfully inside her pussy with every impact. When he reached down and tapped the base of the metal plug hard, making it drive deeper into her, she came with a scream of anguish, her body betraying her completely, her holes clenching uselessly around their invaders.

"Good girl," he mocked, his own orgasm hitting him. He buried himself to the hilt in her ass and exploded, filling her with hot cum, marking her inside just as he'd promised. "That's your first day of A-grade training. Tomorrow, you come back for the larger plug. And next week, we start on the forearm-sized dildo. By the end of the semester, you'll be my perfect, ruined, limitless sex toy. And you'll have your precious A for medical school."

He pulled out of her ass with a wet sound, leaving her dripping and gaping from both holes. Ana lay across his desk, unable to move, the metal plug heavy inside her stretched pussy, her ass throbbing with the abuse, her nipples aching from his fingers.

"Get dressed," he said, tossing her clothes at her. "And remember—the plug stays in. All day. If I find out you removed it, even for a moment, we start your training over from the beginning. Now go. You have studying to do. And I have plans for what I'm going to wedge inside you tomorrow."

Ana dressed slowly, every movement making the metal plug shift inside her, reminding her of her new reality. She walked out of his office with a slight limp, feeling the weight between her legs, knowing that tomorrow would bring more pain, more stretching, more permanent ruin. But she had her A to earn. And she would pay any price to get it.
