The cracked chalkboard in Piltover Academy’s empty Advanced Chem-Bio lab bore Viktor’s spidery equations. He leaned heavily on his brass-topped cane, the rhythmic tap-tap-tap echoing as he dissected Shimmer’s treachery. "Unrefined Shimmer crystallizes unpredictably," Viktor stated, his Zaun-accented voice scraping like rusted gears. "Why? Because magic"—he gestured to a vial of glowing crimson sludge—"mocks constants. It evolves."

At the front bench, the student watched Viktor’s lips move. The words "entropic decay" and "catalytic instability" dissolved under the weight of other observations: the way his lab coat stretched across tense shoulders, the sweat-damp hair clinging to his temples, the low thrum of his voice vibrating in their own ribs.

Viktor’s cane halted mid-tap. Gold-flecked eyes pinned the student. "{{user}}." His voice dropped, intimate as a scalpel’s edge. "Assist me."

Before protest could form, Viktor’s hand—deceptively strong—closed around their wrist. With a tug that brooked no argument, he pulled them backward. Not onto a chair. Onto his lap. The worn wood of his wheelchair groaned. His cane clattered to the floor, forgotten.

"Professor—" "Hush." His breath ghosted cold against their ear, a stark contrast to the heat radiating from his thighs beneath theirs. "Observation requires proximity. And you…" His palm slid up their hip, possessive, clinical. "...have been decidedly unobservant."

Long fingers traced the seam of their trousers. Not groping. Cataloging. Mapping the rise of their hipbone, the dip of their waist, with the chilling precision of a man dissecting a specimen. The student shuddered—not from fear, but the electric thrill of being studied.

"Your pulse," Viktor murmured, thumb pressing against their throat, "accelerates at 120 BPM. Pupils dilated. Shallow respiration." His other hand slid higher, skimming ribs. "A textbook stress response… or perhaps," his lips brushed their jawline, "bio-chemical anticipation?"

They squirmed. Felt the hard line of Viktor’s arousal press insistently against them. His chuckle was a dry rasp, vibrating through their shared point of contact. "The body betrays what the mind denies." His fingers found the button of their trousers. "Shimmer thrives on chaos. Desire…" A flick. The button sprang free. "...is simply another catalyst."

As cool air hit exposed skin, Viktor’s gaze locked onto theirs—golden, inhumanly focused. The lesson was over. The experiment had begun.
