The steam from the cauldron rose in a thick, white plume, curling around the edges of the wooden shelf where the jars of dried herbs and preserved organs sat in neat rows. Harry stood close enough to the bench that his robes brushed against the edge of the stone workstation. Draconia was there too, her body positioned between the bubbling liquid and the wall of jars. The heat from the potion radiated outward, warming her skin and making the air feel heavy. She looked up at him with eyes that were far too bright for a midnight hour in the dungeons.
"You are staring," she said. Her voice was low, a quiet vibration in the damp air of the laboratory.
"It is hard not to," Harry replied. He did not move to finish the final stir of the potion. Instead, he watched the way her breath hitched as she reached for a jar of powdered moonstone. The movement caused her skirt to pull tight against her hips, a silhouette of tension that he could not ignore.
Draconia leaned back against the workbench, her hands finding purchase on the edge of the wood. "The potion is stable. You can stop thinking about the stirring for a moment and actually look at me."
"I am looking at you," he said. He stepped closer, entering the narrow space between the bench and the shelf of jars. His fingers grazed the fabric of her sleeve, but his gaze was fixed on the way her chest rose and fell.
"You are looking at the steam," she countered. She reached out and grabbed the front of his robes, pulling him toward the space where the cauldron hissed. "The potion can wait. The instructions said we had to stay until it was done, but they did not say we had to stay perfectly still."
Harry felt the heat of her palms through his clothes. He moved his hand to her waist, his fingers digging into the soft flesh of her hip. He pulled her closer, pressing her back against the shelf of glass containers. A jar of pickled leeches rattled against the stone, but he did not care. He wanted to feel the press of her body against his.
"Is this part of the instructions?" he asked, his voice dropping an octave.
"It is a deviation from the plan," she whispered. She tilted her head back, exposing the long line of her throat.
Harry did not wait for her to say anything else. He leaned down and captured her mouth with his, his tongue sliding against hers in a hungry, desperate motion. He moved his hand from her hip to the hem of her skirt, bunching the fabric in his fist. He pushed the material upward, sliding his hand up her thigh until his fingers found the damp warmth of her knickers.
He pulled her legs wide, stepping between them so he could press his pelvis against her. The sensation of her wetness through the thin fabric made his own cock ache and throb in his trousers. He groaned into her mouth, a low, guttural sound that made her arch her back. He reached for the fastening of his own trousers, his movements hurried and clumsy in the dim light of the dungeon. When he freed his cock, it sprang out, thick and hot, pulsing with the need to be inside her.
"Harry," she gasped, her eyes snapping open to meet his. She reached down, her fingers wrapping around the base of his shaft. Her grip was tight, and the sensation of her hand on him made him shudder.
He guided her hand down, sliding her fingers over the head of his cock before pushing himself against her. He pushed her skirt higher, pulling it up to her waist until she was completely exposed to the cool air of the room and the heat of the cauldron. He positioned himself, pressing the head of his cock against her slit. He felt the slickness of her cunt coating his skin, a lubricant that made the friction even more intense.
He pushed inside her with one long, heavy thrust. Draconia let out a sharp, choked cry, her fingers digging into his shoulders as he buried his cock deep inside her pussy. The sensation was overwhelming, the tight, wet walls of her cunt gripping him as he slid home. He stayed still for a moment, letting her body adjust to the fullness of him.
"God, you are tight," he muttered, his breath hot against her ear.
"Do not stop," she commanded, her voice a ragged edge of a sound. "Fuck me, Harry. Right here."
He began to move, his hips driving forward in a steady, rhythmic motion. He pulled her hips forward to meet him, his cock sliding in and out of her wet cunt with a wet, slapping sound. Each thrust was deep and deliberate, driving him further into her heat. He watched her face as he did it, seeing the way her eyes rolled back and her lips parted with every stroke.
He increased the pace, his thrusts becoming harder and more frantic. He wanted to feel every inch of her. The friction of his cock rubbing against her clitoris sent jolts of electricity through his spine. He could feel her walls pulsing around him, squeezing his shaft with every movement. He reached down, his thumb finding her nub and rubbing it in circular motions as he continued to fuck her.
"Yes, right there," she breathed, her head thumping back against the shelf of jars. "Harder, Harry. More."
He did not hold back, driving his cock into her pussy with a primal intensity. He felt the build-up in his gut, a mounting tension that threatened to break him. He gripped her thighs, pulling her legs even wider to give him better access to her cunt. The sound of their bodies hitting, the wetness of her sex, and the steam from the cauldron created a feverish atmosphere.
"I am close," he grunted, his movements becoming shorter and faster. "Draconia, I am nearly there."
"Don't you dare stop," she said, her voice breaking as she reached her own peak. Her internal muscles clamped around his cock in a series of intense, rhythmic contractions. He felt her cunt shuddering around him, the heat of her orgasm driving him over the edge.
He let out a low roar, his head snapping back as he emptied himself inside her. He felt his cum erupting from his cock, pulsing deep into her womb. He pushed himself as deep as he could go, his body shaking with the force of his release. He felt the warmth of his cum filling her, a thick, heavy sensation that made him groan with relief.
He stayed inside her for a long time, his breathing heavy and ragged as the intensity of the act slowly subsided. The cauldron continued to bubble beside them, a constant, rhythmic sound in the quiet of the dungeon. He felt her hands sliding down his back, her touch soft and grounding.
"That," she whispered, her voice returning to its usual teasing tone, "was a very efficient use of the time."
He pulled back slightly, watching the way her hair had become a chaotic mess around her face. He felt a sense of triumph, but also a strange, lingering warmth. He reached out to adjust a jar that had shifted during their movement, his hand trembling slightly.
She watched him, a knowing smirk playing on her lips. She saw the way he looked at the shelf, the way he tried to regain his composure in the face of her blatant scrutiny. She knew exactly how to handle the noise of his pleasure, and the way she would use it to keep him under her thumb.
"You missed a decimal point on the dried valerian, Potter," she said loudly, her voice cutting through the silence of the room. She leaned forward, her mouth inches from his, and began to recite the weights of the nearby jars with a clinical, unwavering precision. "Ten grams of crushed beetle carapaces. Five grams of powdered moonstone. Three drams of dried murtlap tentacles."
She spoke the words with a flat, academic tone, her voice acting as a shield to cover the soft, wet sounds of his breathing and the lingering rhythm of her body's reaction.
