The dormitory door clicked shut behind Andromeda, leaving only the crackling fire and the faint howling of the wind outside the castle walls. The Slytherin common room, carved deep beneath the lake, was drenched in cool green light, shadows stretching long and sinuous against the stone. It should have been vast, empty, impersonal. But with Severus standing mere steps away, it felt oppressively small.
Sia remained seated on the couch, back stiff, arms resting on her lap, tension curling around her shoulders like a cloak. Her exhaustion from earlier had nearly lulled her into a heavy sleep, but now she was fully awake, every nerve alert. She watched as Severus remained still, his dark eyes locked onto hers-studying, measuring.
Then, he moved.
Not with the usual sharpness, not with irritation or disdain, but with something else entirely. A quiet certainty. A deliberate smoothness in the way he stepped forward, like a shadow slinking closer. His gaze never wavered, never left her, even as he lowered himself to her level, pausing just at the edge of the couch.
The air changed.
Sia inhaled sharply, her fingers curling into the fabric of her robe, but she did not move away. She should have. She knew better. Knew this was him testing the waters, pushing boundaries-not out of desire, but out of control, calculation.
Severus Snape was nothing if not a strategist.
His fingers barely brushed the couch beside her thigh as he leaned in, exhaling near her neck, the warmth of his breath stark against the cold dungeons. Sia felt her pulse react before she could stop it. A flutter. A hesitation.
"You've been restless," he murmured, voice low, quiet enough that the words ghosted along her skin rather than filled the air.
It was true. She had been. She hated that he had noticed.
His hand, long-fingered and pale, lifted a fraction, hesitating-calculating-before he moved closer still. He was slow, methodical, as though he were reading her reactions like an ancient text, translating her breath, the tension in her shoulders, the faintest flicker in her gaze. His fingertips traced just beneath her jaw, barely there, like the echo of a touch rather than a touch itself.
Sia did not pull away.
And that was a mistake.
Severus took it as permission.
His hand grew bolder, moving along the side of her neck, tracing the delicate skin near her collarbone. Not pressing, not grasping-just existing there, warm and feather-light, his touch sending a strange, shivering awareness down her spine. His thumb brushed the spot where her pulse beat a little too fast.
"I wonder," he mused, voice quieter now, "why you didn't expect this."
His lips were dangerously close to the shell of her ear, his breath warm against the chilled air. The robe she had carelessly loosened before her nap-the first two buttons undone-suddenly felt like a fatal oversight. His fingers barely traced the column of her throat, lingering just at the hollow before drifting lower, pausing just above the undone buttons.
Her breath hitched.
She knew what he was doing. She knew.
But knowing didn't change the way her body reacted.
Sia forced herself to move-just barely. A millimeter forward, a fraction of space closed between them before her mind screamed at her to stop. And she did, breath catching, realization striking her like a hex.
No.
Not him.
She jerked back, meaning to create distance, but in her haste, she miscalculated.
Her back met the couch instead, trapping her in a position she hadn't planned. She had intended to escape, to reassert control, but instead, she had placed herself lower, half-reclined, with Severus looming above.
His gaze darkened.
It was a small movement, a simple shift, but it had changed everything. He leaned in, one knee pressing onto the couch beside her thigh-not touching, not quite-just there. A deliberate placement. A quiet checkmate.
Sia swallowed hard.
"You're afraid," he noted, but there was no mockery in his tone. Only quiet observation.
"I'm annoyed," she corrected, though her voice betrayed her.
He tilted his head slightly, studying her like a puzzle he was piecing together. His hand, the one that had lingered at her collar, now braced against the back of the couch behind her, trapping her in a cage of space. His other hand lifted again, this time tracing with just the barest pressure along the slope of her throat, dipping to the collar of her robe.
"Soft," he murmured.
Sia stiffened.
That was too much. That was-
She shoved at his shoulder. Not hard, not violently, just enough to break the spell.
Severus allowed it.
Barely.
His dark eyes flickered, something unreadable in them, before he pulled back a fraction. His hand lingered near her throat a second longer before he withdrew it entirely, slow and deliberate.
Sia exhaled, suddenly aware she had been holding her breath.
They stared at each other.
Whatever game he had been playing, whatever lines had been tested, she had lost this round. Because she could still feel the ghost of his touch. Still feel the whisper of his breath at her ear.
Severus leaned back finally, settling onto the couch beside her rather than above her. He studied her, unreadable once again, before his lips curled-just slightly.
Not a smirk. Not triumph.
Something else.
Amusement.
"You should be more careful," he murmured, his voice smooth, his tone edged with something she couldn't quite decipher.
Sia forced herself to sit up properly, to put proper space between them, to realign her thoughts.
"I'll keep that in mind," she said, voice level.
Severus hummed as if he found that interesting, before standing to his full height. He straightened his robes, composed as ever, before glancing at her one last time.
Then, without another word, he turned and walked away, disappearing up the boys' dormitory stairs.
Sia let out a slow breath and closed her eyes.
She had been right about him.
He was dangerous.
But the most dangerous part?
For a moment-just a moment-she hadn't wanted to move away.
