The Charms classroom was silent, save for the sound of her own breathing. Draconia sat on the edge of the professor’s heavy oak desk, her skirts bunched around her thighs. She had drawn her right knee up high, the fabric of her robes pulling tight against her hip. Beside her cheek, she had placed her wand, standing upright in a small wooden stand so that the tip rested just inches from her temple. It was a ridiculous tableau, a piece of staged theatre designed to provoke, and she felt the familiar thrill of control as she watched Harry stare at her.
"You look like you are waiting for an audience, Draconia," Harry said, his voice a low rasp in the empty room. He stood a few feet away, his wand loosely in his hand, looking far too composed for a man who had just watched a girl adjust his grip with such precision.
"I do not need an audience when the subject is so captive," she replied, tilting her head so the wand tip grazed her skin. She offered him a sharp, predatory smile. "It is a matter of scale, isn't it? You always seem to struggle with the finer details of a hold. Perhaps you need something more substantial to practice on."
Harry took a step closer, his eyes fixed on the way her knee protruded from the hem of her skirt. "Is that what this is? A lesson in scale?"
"It is a lesson in capacity," she corrected, her voice smooth and clinical. She reached out, her fingers tracing the grain of the wood on the desk. "A wand is only as effective as the hand that directs it. If the tool is too small, the magic feels wasted. If the tool is too large, the witch cannot command it. It is all about the proportion of the thing to the person."
He moved into her space, the heat of his body radiating against her skin. He reached out, not for her hand, but for the wand standing beside her face. He gripped it, his fingers wrapping around the dark wood, and he held it upright, mirroring her pose. "So, you are saying the size of the wand is the problem?"
"I am saying the wand is irrelevant if the grip is weak," she said, her voice dropping an octave. She reached out and placed her hand over his, her fingers splaying wide. She felt the strength in his hand, the thickness of his fingers, and she leaned into the joke, pushing it further. "But perhaps we should test the strength of the grip instead of the length of the wood."
She stood up on the desk, her legs bracing against the wood as she pulled him toward her. The movement was sudden, and he stumbled forward, his hands finding her waist to steady her. Draconia did not wait for him to settle; she wrapped her legs around his waist, her thighs squeezing his hips. The friction of her silk knickers against his trousers sent a jolt through her, but she kept her expression bored, almost mocking.
"Is this a better grip, Potter?" she whispered against his ear, her teeth grazing the lobe. "Or is it still a bit too much for you to manage?"
Harry groaned, a low, guttural sound that broke through her poised exterior. He gripped her ass, his fingers digging into the soft flesh through the heavy fabric of her robes. He pushed her back until she was sitting flat on the desk, her legs still hooked around him. He fumbled with his trousers, the sound of a heavy zipper cutting through the silence of the classroom. He pulled his cock free, and it was thick and angry in the dim light.
Draconia looked down at him, her eyes bright with a hunger she refused to name. She reached down, her fingers wrapping around his cock. He was hot and pulsing, the skin taut and smooth. She slid her hand up and down the length of him, watching the way his hips jerked upward to meet her touch.
"It is quite a formidable thing, isn't it?" she teased, her voice dripping with a fake, academic seriousness. "Very impressive. Almost a shame to use it so clumsily."
"Shut up," Harry breathed, his eyes dark with want. He reached for the front of her robes, pulling the heavy fabric open to reveal the pale skin of her stomach and the lace of her knickers. He shoved his fingers inside the waistband of her silk, pushing the fabric aside until he found her pussy.
She was already wet, her juices slicking the entrance to her cunt. He slid two fingers inside her, stretching her wide as he moved them in a rhythmic, punishing motion. Draconia gasped, her head falling back, her hair still pinned in its tight, severe bun. She watched him, her eyes tracking the way his thumb rubbed against her clitoris, the blunt pressure of his touch making her insides throb.
"Is this... the correct technique?" she asked, her voice breaking as he pushed a finger deeper.
"You're a cruel bitch," Harry muttered, his voice thick. He pulled his fingers out and gripped his cock, the base of it rubbing against her clitoris as he guided himself toward her opening. He pushed the head of his cock against her wet slit, and she felt the immense pressure of him. He slid inside her in one long, heavy stroke, filling her completely.
Draconia let out a sharp cry, her fingers digging into his shoulders as he began to fuck her. He moved with a frantic, desperate pace, his hips slamming against her pelvis with a rhythmic thud. Every time he thrust, the desk creaked under their combined weight. He was deep, hitting the very back of her cunt, and the sensation was overwhelming. She felt the stretch of him, the fullness of his cock stretching her walls to the limit.
"Harder," she commanded, the joke still dancing on her lips even as her eyes glazed with pleasure. "You are being too careful. A witch does not want a gentle touch; she wants to be conquered."
Harry obliged, his movements becoming more violent. He gripped her thighs, pulling them wider to give him better access. He drove himself into her, his cock sliding in and out of her soaking wet cunt with a wet, slapping sound. She could feel the heat of him, the friction of his skin against hers, and the sheer size of him as he filled her. She reached down, her hand finding the base of his shaft, guiding him as he hammered into her.
"Is the... size... alright?" she gasped, her breath hitch, her hips bucking to meet every lunge.
"It's perfect," he growled, his teeth bared in a grin of pure, unadulterated lust. He pushed harder, his thrusts becoming short and rapid. He was reaching his limit, and he could feel the tension building in his groin. He drove into her one last time, burying himself as deep as he could go, and then he began to cum.
He shoved himself into her, his cock pulsing inside her womb as he emptied himself into her. Draconia felt the hot, thick squirt of his cum filling her, a sensation so intense it made her entire body shudder. She wrapped her arms around his neck, pulling him down so she could feel the weight of his chest against hers. As he finished, he pulled out of her, the wet, sticky sound of his exit echoing in the room. He slumped against her, his breath coming in ragged gasps, as a heavy string of cum dripped from her pussy and onto the wood of the desk.
She sat there, her hair still perfectly in place, her expression returning to one of cool, detached amusement. She looked at the wand still standing by her cheek, and then back at him. It was entirely her idea, and she had run the joke the whole way through.
