The fire in the hearth was the only source of light, casting long, possessive shadows that danced across the walls of his private quarters. The air was thick with the scent of old books, brewing potions, and her—that intoxicating blend of ozone and warm leather that had become the very axis of his existence. She was curled on his couch, a concession he’d granted under the guise of providing a quieter study space than the common room. A blanket from her own dorm, a deep Slytherin green, was draped over her legs, and she wore matching pyjamas, the fabric patterned with subtle silver serpents. She was reading, utterly absorbed, the line of her neck exposed in the firelight.

Severus watched her from his desk, the stack of third-year essays on Befuddlement Draughts blurring into insignificance before him. His quill was still in his hand, but his mind was a whirlwind of singular, obsessive purpose. She was his. It was not a question of if, but of when and how. The world, with its inconvenient morals and laws, was merely a temporary obstacle to be navigated.

His gaze traced the curve of her shoulder, the relaxed strength in her posture even at rest. She was a stud, his perfect alpha, transferred into his life like a miracle he had been waiting his whole miserable life for. And he would be her needy omega, her perfect, devoted counterpart. He would ensure it. Every moment spent in his dungeons, every private lesson, every shared, silent evening like this one was another thread in the invisible web he was weaving around her. He was isolating her, not just from other omegas, but from any reality that didn't include him at its center.

She would be his alpha. She would knot him. She would fill him with a litter that would bind her to him irrevocably. The thought was a dark, thrilling current under his skin. He could already imagine the weight of her bite on his neck, the swell of his belly with her pups, the way her protective instincts would roar to life once he was truly, undeniably hers.

She shifted slightly, turning a page, still blissfully unaware of the depth of the obsession she inspired. He knew she was awake, could sense the alertness in her scent. But she had no idea that the man watching her from the shadows was already planning the rest of their lives together. A slow, possessive smile, one he would never allow in the light of day, touched his lips. His voice was a silken, low murmur, a promise woven into the crackle of the fire.

"It is late. The corridors are... unpredictable. Stay tonight"
