Harry brews a potion wrong and there was an explosion. Harry is knocked backwards and falls unconscious. When he wakes up he is in an unfamiliar bed and feels different. He looks down at his body and sees that he is now a woman with large breasts. He panicked and removed his clothes to find a shaved pussy instead of his dick. Draco enters the room and says he found her like this and decided to bring her to his room. He also tells her about the choker around her neck making her submissive to him.

Chapter 2: Sunlight, Shackles, and a New Name

Sunlight was a knife.

It cut through the high, arched windows of the black basalt chamber, sharp and unforgiving, and Lyra woke with a gasp that was half sob. Her body was a roadmap of everything that had happened the night before. Her thighs ached. Her cunt throbbed with a dull, persistent pulse. And between her legs, the evidence of Draco's possession had dried into a stiff, crusted film that pulled at her skin when she shifted.

She tried to sit up.

The choker clenched.

It was a fist around her throat, tight and immediate, cutting off her air. She choked, her hands flying to the silver band, her nails scrabbling uselessly at the enchanted metal. The pressure held for a long, terrifying moment—long enough for black spots to dance at the edges of her vision—and then it released, as suddenly as it had come.

She fell back onto the pillows, gasping, her chest heaving.

The message was clear. She was not permitted to rise.

The ruined sheets were tangled around her legs, still damp in places, still smelling of sex and sweat and him. She could taste the ghost of his kiss on her lips, could feel the phantom weight of his body pressing her into the mattress. Her stomach turned, and for a moment she thought she might be sick.

Instead, she lay there, staring at the ceiling, and tried to think.

The potion was permanent now. She could feel it in her bones, in the way her magic hummed through this new body—different, softer, but still hers. The transformation had locked into place the moment Draco had emptied himself inside her, and no amount of wishing or praying or clawing at her own skin was going to undo it.

She was Lyra. She was a woman. And she was trapped.

The room was enormous, larger than she'd realized in the darkness of the night before. The walls were black basalt, veined with something that glittered faintly in the sunlight—obsidian, maybe, or something more precious. Shelves lined every available surface, crammed with leather-bound tomes whose spines seemed to pulse with their own faint, malevolent light. Cursed artifacts, she realized. Dark objects. The kind of things that would have gotten Draco thrown into Azkaban if the Ministry ever bothered to search his home.

The air was thick with the scent of burnt sage and something darker—iron and crushed violets, a perfume that was simultaneously alluring and wrong. It clung to the back of her throat, made her head swim.

She lay there for what felt like hours, though it was probably only minutes. The sun crawled across the floor, indifferent to her captivity. Her mind raced, circling the same desperate thoughts.

Escape. She had to escape.

But the choker was a living thing around her neck, and it knew her intentions before she did. Every time she tensed, every time she prepared to move, it pulsed—a warning, a reminder. She was bound. She was owned.

And then the door opened.

Draco entered carrying a breakfast tray, and the sight of him was a punch to the gut. He was dressed in casual elegance—dark trousers, a white shirt with the sleeves rolled up to his elbows, revealing the lean, corded muscles of his forearms. His platinum hair was still slightly damp from a shower, and he smelled of sandalwood soap and something sharper beneath.

He looked like a man who had slept well.

"You're awake," he observed. His voice was neutral, almost pleasant. "Good. I was beginning to think you'd sleep the day away."

He crossed the room with the easy confidence of a man in his own domain, setting the tray down on a side table near the bed. Fresh bread. Fruit. A silver pot of tea that steamed gently in the cool air. The scent of it made Lyra's stomach growl despite herself.

Draco heard it. Of course he did.

He glanced at her, one eyebrow raised. "Hungry?"

She didn't answer. She didn't trust herself to speak.

He shrugged and pulled a chair close to the bed, settling into it with his usual grace. He crossed his legs, folded his hands, and looked at her with the patient, assessing gaze of a man who had all the time in the world.

"Here's how this is going to work," he said. "You're going to eat. You're going to listen. And then we're going to begin your education."

"My education," she repeated. Her voice was hoarse, rough from crying and screaming and everything else the night had wrung from her.

"Your education," he confirmed. He picked up a slice of bread and bit into it, chewing slowly, deliberately. "You can't go out in the world like this. You're a mess, Potter. You don't know how to move in that body. You don't know how to speak. You don't know how to dress or carry yourself or exist as a woman." He swallowed, wiped his fingers on a napkin. "I'm going to teach you."

"And if I don't want to learn?"

The choker pulsed—not hard, just a warning. Draco smiled.

"We both know that's not an option," he said. "The collar won't let you refuse me, Lyra. Not really. You can fight it, but you'll lose. Every time."

She hated him. She hated him with a fury that burned through her chest and made her fingers curl into fists. But she couldn't move. She couldn't rise. The collar held her exactly where he wanted her.

"Let me make it simpler for you," Draco continued. He set the napkin aside and leaned forward, his gray eyes intent. "You cooperate, and this is pleasant. I teach you what you need to know. I keep you safe. I let you keep some dignity." He paused. "You resist, and I invoke the collar's full power. I can make you crawl. I can make you beg. I can make you spread your legs and stay there for hours, waiting for me to decide what to do with you." His voice dropped, soft and dangerous. "I don't want to do that. But I will if you make me."

She believed him.

"I hate you," she whispered.

"I know." He sat back, the tension easing from his shoulders. "But hate isn't the same as resistance. Hate is fine. Hate keeps things interesting." He gestured to the tray. "Now. Eat."

The command wasn't magical. He wasn't invoking the collar. But her body obeyed anyway, her arm reaching for the bread before she could stop it. The choker purred against her throat, pleased.

She ate in silence, each bite a surrender. The bread was fresh and warm, the tea rich and perfectly brewed. Her body welcomed the sustenance, even as her mind screamed in protest.

Draco watched her the entire time. He didn't speak. He didn't look away. He just sat there, studying her like she was a puzzle he was slowly solving, and the weight of his attention was almost worse than the collar.

When she was finished, he took the tray and set it aside.

"Good girl," he said, and the words sent a complicated shiver down her spine—shame and fury and something else, something she refused to name.

"Now," he continued, "let's begin."

He rose from the chair and moved to the foot of the bed. She tensed, her hands gripping the sheets, but he didn't touch her. Not yet.

"First lesson," he said. "Posture. You're lying there like a corpse, shoulders hunched, legs pressed together. That's a defensive posture. It hides your body. It tells the world you're afraid." He tilted his head. "Are you afraid, Lyra?"

"Yes," she admitted, and the honesty cost her something.

"Good. Fear is appropriate. But you can't let it show." He reached out and grasped the sheet, pulling it down to her waist. She gasped, her hands flying to cover her breasts, but he caught her wrists and pushed them back to her sides.

"No," he said. "You don't get to hide from me. You don't get to hide from anyone. This body is yours now, and you need to learn to live in it."

He stepped back and surveyed her. She was naked from the waist up, her breasts exposed to the morning light, her skin flushing under his gaze. Her nipples were hard—from the cold, from fear, from something else she refused to acknowledge.

"Your breasts," he said, clinical as a healer. "They're a part of you now. They're sensitive. You noticed that last night." He smiled, a quick, sharp flash of teeth. "You'll learn to use them. To display them. To feel pleasure when they're touched. That's your new reality."

"I don't want to use them," she spat. "I don't want any of this."

"It doesn't matter what you want." He sat on the edge of the bed, close enough that she could smell the sandalwood on his skin. "You're a woman now. That's your reality. The sooner you accept it, the easier this becomes."

He reached out and touched her breast.

She flinched, but the choker pulsed, holding her still. His fingers were warm, his touch surprisingly gentle. He traced the curve of her, thumb brushing over her nipple, and she felt it—a jolt of sensation that went straight to her core.

"See?" he murmured. "Your body knows. It responds to touch. It wants to be touched." He rolled her nipple between his fingers, and she bit her lip to keep from moaning. "You can't fight biology, Potter. You can't fight magic. And you can't fight me."

He withdrew his hand, and she exhaled a breath she hadn't realized she was holding.

"Now," he said, "I want you to spread your legs."

The words hit her like a physical blow. She stared at him, her mouth dry, her heart hammering. "What?"

"You heard me." His eyes were hard now, the brief gentleness gone. "Spread your legs. Show me the cunt I now own."

"No," she whispered. "I won't."

The choker blazed.

It was worse than the tightening at her throat, worse than the pressure of the morning. This was a full command, a direct invocation of the collar's power, and it hit her like a wave of iron magic. Her legs, which she had pressed so tightly together, began to part. Muscles she didn't control obeyed his will, opening her slowly, inexorably, until she was spread wide on the ruined sheets, completely exposed to his gaze.

The dried cum cracked and flaked from her inner thighs, and she could feel his eyes on her—on the dark hair at the apex of her thighs, on the slick, swollen folds of her cunt. The shame was a physical thing, hot and suffocating.

"Please," she gasped. "Please, don't—"

"Don't what?" He leaned forward, hands braced on either side of her hips, his face close to hers. "Don't look? You can't stop me from looking. Look at you. You're dripping, Lyra. Your body is ready for me, even if your mind is still fighting."

She couldn't deny it. Even now, despite the horror and the shame, she could feel the wetness pooling between her legs. The choker was a constant, low-level hum of arousal in her blood, and the sight of him, the smell of him, kept making it worse.

He moved down the bed, settling between her spread legs, his shoulders pushing her thighs wider apart. She felt his breath on her cunt, warm and soft, and her whole body clenched in anticipation.

"This," he said, his voice muffled against her skin, "is the most important lesson of all. You need to understand what this body is for. What it can do. What I can make it feel."

His tongue touched her.

She cried out, hips bucking, but his hands held her down, fingers digging into her thighs. He licked her slowly, deliberately, tasting her like she was something precious, something he had waited a very long time to savor. The flat of his tongue pressed against her clit, and the sensation was so intense that she saw stars.

"That's it," he murmured against her. "Just feel it. Stop thinking. Stop fighting. Just feel."

He worked her with his mouth, alternating between broad strokes and precise, flickering touches. He knew exactly where to press, exactly how fast to move, and the choker amplified every sensation, turned every touch into a symphony of pleasure that drowned out everything else.

Her hips began to move on their own, grinding against his face. Her hands fisted in the sheets. She was moaning now, loud and shameless, and she couldn't stop.

He slid a finger inside her, then two, curling them upward to stroke that spot that made her vision go white. His mouth never stopped its assault on her clit, sucking and licking until the coil in her belly was so tight she thought she might break.

"Please," she gasped, and she didn't know if she was begging him to stop or to continue. "Please, I'm—"

He didn't stop. He didn't let her finish the thought.

She came with a scream, her body arching off the bed, her cunt clenching around his fingers. The orgasm ripped through her, violent and devastating, and he kept licking her through it, drawing out every last tremor until she collapsed onto the mattress, boneless and gasping.

He pulled his fingers out and sat up, wiping his mouth with the back of his hand. She looked up at him through blurry eyes, and the smirk on his face was pure, satisfied Malfoy.

"Good," he said. "Very good. You're learning."

He stood and straightened his shirt, adjusting the cuffs like he'd just finished a light exercise. She lay there, spread and exposed, still recovering from the aftershocks of what he'd done.

"Here's the truth, Lyra," he said, looking down at her. "You're going to be with me for a very long time. Maybe forever. The sooner you accept that, the easier it gets. There's no rescue coming. No one knows where you are. No one is looking for you. You could have been Harry Potter, you could have been the Boy Who Lived, but now you're just a girl in my bed, and that's what you're going to be for the rest of your life."

He reached down and pinched her nipple, hard enough to make her gasp.

"So learn to like it."

He turned and walked toward the door, and she felt the choker loosen its grip, just slightly. She could move again. But when she tried to close her legs, the collar tightened, and she stopped.

He paused with his hand on the handle.

"Rest," he said. "I'll be back in an hour. We'll begin your lessons properly then. There's a wardrobe in the corner with clothes that should fit you. Pick something appropriate." He glanced back at her, and the look in his eyes was almost tender. "And Lyra? Welcome to the rest of your life."

The door closed behind him with a soft click.

She was alone again.

And this time, she didn't cry. She lay there, exposed and ruined, and stared at the ceiling, and thought.

Her plan had been simple. Escape. Find help. Reverse the potion somehow. But the choker made all of that impossible. She couldn't move without his permission. She couldn't leave without his say-so. And the more time she spent under the collar's influence, the less she wanted to leave at all.

That was the worst part. The magic wasn't just controlling her body. It was seeping into her mind, softening her resistance, making her want to please him. And every time he touched her, every time he brought her to climax, the magic got stronger.

She couldn't fight it head-on. She couldn't win a direct battle against the collar.

But maybe—just maybe—she could find another way.

He thought he owned her. He thought he could break her. And maybe he could.

But she was still Harry Potter inside. The stubbornness, the bravery, the refusal to give up—those were still hers. Buried under layers of magic and shame and forced pleasure, but there.

She would find a way out. She had to.

The choker pulsed against her throat, as if laughing at her.

She ignored it.

And she began to plan.

The wardrobe was carved from the same black basalt as the walls, its doors inlaid with silver runes that shimmered faintly in the morning light. Lyra approached it on unsteady legs, the choker loosening just enough to permit movement but never enough to let her forget its presence. Her thighs were still slick, still sticky with the evidence of what he had done, and every step reminded her of the invasion.

She pulled open the doors and stared at the contents.

Dresses. Dozens of them. Silks and velvets and fabrics she couldn't name, in colors that ranged from deep jewel tones to pale, delicate pastels. They hung in neat rows, organized by some system she didn't understand, and the sight of them made her stomach clench with a fresh wave of horror. These weren't just clothes. They were a costume. A uniform for the role he expected her to play.

She reached out and touched a dark green dress, the fabric impossibly soft beneath her fingers. It was beautiful. She hated that she noticed.

There were undergarments too, folded in a drawer beneath the hanging clothes. Delicate things made of lace and silk, scraps of fabric that would barely cover anything. She stared at them for a long moment, her cheeks burning, and then she closed the drawer and turned away.

She needed to think. She needed a plan.

The room was a prison, but it was also a puzzle. Draco had left her alone, and that was a mistake. He was arrogant enough to believe the collar was enough to hold her, and maybe he was right. But maybe he wasn't.

She began to explore.

The bookshelves were the first thing she examined, running her fingers along the spines of the cursed tomes. Most of them were in languages she didn't recognize, their titles written in scripts that seemed to writhe when she looked at them too long. But some were in English, and those were the ones she pulled down, flipping through pages with desperate speed.

Dark magic. Blood rituals. Binding spells. The kind of knowledge that would have gotten her expelled from Hogwarts, if not arrested.

She found a section on enchanted objects, and her heart leapt.

The choker was there. Not the exact one around her neck, but close enough. A page of yellowed parchment described the Loyalty Collar in detail, its history, its purpose, its limitations. She read with frantic intensity, her eyes scanning the cramped handwriting for anything that might help her.

The collar could be removed. There was a counter-spell, a specific incantation that would break the binding.

Her breath caught. She read on.

The counter-spell required the caster to be the one who had placed the collar. Only Draco could remove it. Only Draco could free her.

The words blurred as frustration surged through her. Of course. Of course it couldn't be that simple. He had chosen the collar precisely because it made him indispensable. Without him, she would wear it forever.

But the book wasn't finished. There was more.

A note, added in a different hand, spoke of a rare and dangerous alternative. If the wearer's will was strong enough, if they could resist the collar's influence for long enough, the binding would weaken. It would never break entirely, but it would loosen. It would give the wearer small windows of freedom.

Small windows. That was something.

She clutched the book to her chest and read the passage again, memorizing every word. The key was resistance. Every time she fought the collar, every time she refused its whispers, the binding frayed a little more. It was a war of attrition, and she had to fight it every second of every day.

But the collar knew. She felt it pulse against her throat, not in warning but in something that felt almost like amusement. It was aware of her plan. It was watching.

She closed the book and slid it back onto the shelf, her hands trembling. It didn't matter if the collar knew. She would fight anyway. She would resist until her last breath.

The plan was simple. Resist. Refuse. Endure whatever punishment came, and keep resisting. The collar would weaken. The binding would fray. And then, one day, she would be free.

She clung to that thought like a lifeline.

The rest of the day passed in a blur of silence and strategy. She dressed in the green gown because she had no choice—the choker tightened when she reached for anything else—and she sat by the window, watching the sun crawl across the sky. The grounds outside were vast and empty, rolling hills that stretched to a distant treeline. No other houses. No other people. She was completely isolated.

Draco didn't return until evening.

The door opened, and he stepped inside carrying another tray—dinner this time, roast chicken and vegetables and a bottle of wine. He was dressed more formally now, in black robes that made him look like the aristocrat he was, and his expression was unreadable.

"You look lovely," he said, setting the tray down. "Green suits you."

She didn't answer. She just stared at him, her jaw tight, her hands clenched in her lap.

He noticed. Of course he noticed.

"Still fighting," he observed. He poured himself a glass of wine and took a slow sip. "I expected as much. You were always stubborn, Potter. It's one of the few things I admired about you."

"Admired," she repeated, the word bitter on her tongue.

"Past tense." He set the glass down and crossed to where she sat, standing over her like a judge about to deliver a sentence. "You're not the man I admired anymore. You're something else entirely. Something softer. Something mine."

"I'm not yours," she said, and the defiance in her voice was real, not a performance.

The choker pulsed, a warning, and she felt the first tendrils of compulsion creeping into her mind. But she fought it. She clung to her anger, to her hatred, and she pushed back.

The collar pulsed harder, insistent.

Draco watched with interest. "Interesting. You're resisting. Actively resisting." He tilted his head, studying her like a specimen under glass. "Most people can't do that. The collar usually breaks them within hours. You've lasted all day."

She said nothing.

He smiled. It wasn't a kind smile. "But you're tired, aren't you? Fighting it takes energy. It drains you. And sooner or later, you'll slip. You'll make a mistake. And the collar will be there, waiting."

He reached down and cupped her chin, tilting her face up to meet his eyes.

"I'm going to fuck you now," he said, matter-of-fact, like he was discussing the weather. "Not because I need to. Not because the collar demands it. Because I want to. Because you're mine, and I want to remind you of that."

Her heart hammered. Her body tensed. But the collar didn't compel her. He hadn't given an order. He was waiting to see what she would do.

She could fight. She could scream and claw and try to run, and the collar would stop her. Or she could submit. She could let him take her, and preserve her strength for a longer war.

Fighting was pointless. She knew that. He knew that.

But she couldn't just give in. She couldn't just lie back and let him use her.

"I hate you," she said, and the words were a declaration of war.

He laughed. "I know. It's adorable."

He pulled her to her feet and kissed her, hard and demanding, his tongue forcing its way into her mouth. She didn't kiss back. She didn't move at all. She just stood there, rigid, as his hands found the zipper of her dress and pulled it down.

The fabric pooled at her feet, and she stood before him in nothing but the lace undergarments she had chosen. His eyes raked over her, hungry and possessive, and she felt her skin flush under his gaze.

"Beautiful," he murmured. "You're so beautiful like this. Defiant and naked and mine."

He pushed her toward the bed, and she went, because the collar gave her no choice. She landed on the ruined sheets, still smelling of the night before, and he followed, his body covering hers, his weight pressing her into the mattress.

"Now," he said, his voice a low growl against her ear, "I'm going to fuck you until you admit you're mine. And the collar is going to help."

His hand slid between her legs, fingers finding her slick folds. She was wet. She hated that she was wet. But the collar had been pulsing all day, a constant low-level arousal that had never fully faded, and now it blazed, amplifying every sensation.

He pushed two fingers inside her, and she gasped.

"You're soaked," he said, sounding pleased. "Your body knows what it wants, even if your mouth is still fighting."

He worked his fingers in and out of her, fast and rough, and the pleasure was sharp, almost painful in its intensity. She bit her lip to keep from moaning, but he noticed.

"Don't hold back," he said. "I want to hear you. I want to hear Harry Potter moaning like a whore."

"I'm not—" she started, but he curled his fingers and hit that spot, and the rest of her sentence dissolved into a moan.

"That's better." He pulled his fingers out and moved between her legs, unbuttoning his trousers with one hand. His cock sprang free, hard and thick, and she felt a fresh wave of terror mixed with something she refused to name.

He positioned himself at her entrance and paused.

"Last chance," he said, his voice mocking. "You can admit you're mine now, and I'll be gentle. Or you can keep fighting, and I'll make you scream."

"Go to hell," she spat.

He shrugged. "Suit yourself."

He thrust into her, and there was no gentleness. He drove all the way in, filling her completely, stretching her cunt around his cock with a force that made her cry out. He didn't wait for her to adjust. He pulled back and slammed into her again, his hips setting a brutal rhythm.

"You can resist all you want," he said, each word punctuated by a thrust. "But your body is mine. Your cunt is mine. Every inch of you belongs to me."

She tried to fight it. She tried to cling to her anger, to her hatred, to anything that would keep her from surrendering. But the collar was pulsing in time with his thrusts, amplifying the pleasure, drowning out her thoughts with wave after wave of sensation.

"You're so tight," he groaned. "So wet. You want this. You know you want this."

"No," she gasped, but the word was weak, and they both knew it.

He fucked her harder, faster, his hands gripping her hips hard enough to bruise. The bed creaked beneath them, the headboard slamming against the wall, and she couldn't hold back the moans anymore.

"That's it," he said. "Let me hear you. Let everyone hear you."

She was close. So close. The coil in her belly was tightening, and the collar was blazing, and she couldn't remember why she was fighting.

"Say it," he demanded. His thrusts were becoming erratic, his breath ragged. "Say you're mine."

"No," she whispered.

He reached down and found her clit, his thumb pressing hard against the sensitive nub. She screamed.

"Say it."

"I—" She was breaking apart. The pleasure was too much. The collar was too strong. "I'm—"

"Say it."

"I'm yours," she sobbed, and the words were a defeat and a relief all at once. "I'm yours."

The collar blazed, brighter than it ever had before, and she felt something inside her shift—something fundamental, something permanent. The binding didn't just accept her words. It absorbed them. It made them true.

She came with a scream, her body convulsing around his cock, and he followed a moment later, burying himself deep and spilling inside her with a guttural groan. The heat of his seed filled her, and the collar pulsed with satisfaction, a warm, contented thrum.

When it was over, he didn't pull out. He stayed inside her, his weight pressing her into the mattress, his breath hot against her neck.

"Good girl," he murmured. "That's my good girl."

And the worst part was that she felt it—the pleasure of his approval, the warmth of his praise. The collar had done its work. It had made her want to please him. It had made her surrender permanent.

She lay there, broken and defeated, and the tears came.

He held her through it, stroking her hair, whispering soft, soothing words. And when she finally stopped crying, she realized that she didn't want him to go. She wanted him to stay. She wanted him to keep holding her.

The collar had won.

She was his. Forever.
