Miki stepped fully onto the slick tile, her bare foot sliding with a soft, wet squelch, the magical lube oozing between her toes, sending a shiver up her spine as her knees knocked briefly.
She caught herself, blinking rapidly, her flushed cheeks glowing in the chamber's crimson haze, then turned to Kota with a sheepish, quivering smile, her ponytail swaying against her sweat-dampened neck.
"I, uh… okay. Just tell me what to do," she said, her voice trembling with nervous anticipation.
The chamber pulsed faintly, a sultry hum rippling through the slick, gel-coated tiles, the other three pads dimming as Miki's glowed brighter, its runes flaring with lewd intent.
The translucent display above the rune pedestal flashed, cold and commanding:
Pad One: ACTIVE. Awaiting stimulation input.
Kota stayed back, two steps from the pad's edge, his hoodie clinging to his frame, sweat beading on his brow as the game's interface prickled with the trial's stakes.
His voice dropped to a calm, steady cadence, cutting through the sweltering haze.
"Sit down. Legs forward. Use your right hand."
Miki obeyed, moving slowly, her gaze flickering to Reina, then Aika, their stony silence a weight in the musky air.
She lowered herself onto the gel tile, the lube squishing beneath her, coating her thighs with a warm, slick sheen that made her breath hitch, her shorts already soaked from the chamber's earlier trials.
Kota's voice continued, unwavering. "Your left hand—hold the floor behind you for balance. Don't move too much. It's about rhythm, not friction."
Miki nodded, her flushed face deepening to a scarlet glow, spreading her legs across the tile, the gel's heat seeping into her skin.
Her shorts clung tightly, outlining her curves; she tugged them down just enough to bare her slick, exposed core, her fingers trembling as she positioned herself, a bead of sweat tracing down her flushed collarbone.
She hesitated, her breath shallow, eyes darting to Kota. "Do I… start?"
Kota's tone deepened, a half-register lower, resonating with the chamber's pulse. "Not yet. Wait for the beat."
The tile beneath her throbbed once, then again, then again—a faint, rhythmic pulse that echoed through her body, the game's lust mana syncing with her nerves.
"Now," Kota commanded, his voice firm. "Two fingers. Circular motion. Match the pulse. One… two… one… two."
Miki complied, her right hand slipping between her thighs, two fingers gliding in a slow, circular rhythm over her slick folds, the lube amplifying every touch with a scalding, electric warmth.
Her breathing tightened, a soft gasp escaping her parted lips as the pad glowed brighter, its runes flaring in sync with her motions, the chamber's walls humming with perverse approval.
Behind her, the other girls stood frozen, their breaths uneven in the musky haze.
Reina's eyes narrowed, a flush creeping up her jaw.
Aika's jaw clenched, her fingers twitching faintly, still sore from her trial.
Hina's scowl deepened, her arms crossed tighter, a bead of sweat betraying her tension.
Yuri's coy smile faltered, her gaze locked on Miki, a subtle quiver in her stance.
Kota's eyes never left Miki, his voice steady, guiding her through the game's cruel rhythm.
"Don't go faster. Keep your pace. One… two…" he instructed, his tone a lifeline in the chamber's sweltering pull.
Miki whimpered, a soft, embarrassed sound, her fingers circling faster despite herself, her flushed thighs trembling as the lube's heat intensified, her core clenching with each pulse.
Her lips parted again, a sharper gasp breaking free—not from shame, but from the game's relentless stimulation, her body betraying her with a needy shudder.
Her hips twitched, rocking slightly against the tile's slick surface.
"Stop rocking," Kota ordered, his voice cutting through her haze. "Focus on your fingers. Not your hips."
She moaned through her nose, a muffled, desperate sound, her left hand gripping the floor for balance, her knuckles whitening as she fought to obey, her fingers maintaining the one-two rhythm, the lube-slicked tile pulsing in sync, its glow bathing her flushed form in crimson light.
"Keep going," Kota said, his gaze unwavering. "When the pad flashes white, hold that rhythm. Lock it in."
The tile throbbed twice, then flared white, its runes blazing with approval as Miki's fingers hit the perfect cadence, her core tightening, her moans rising in pitch, echoing off the chamber's slick walls. Kota stepped back, his breath steady despite the trial's heat.
"Sync point one: locked."
The display updated, its text pulsing with cold authority:
Pad One: Synced. Awaiting others.
Miki collapsed back onto the tile, her chest rising and falling with rapid, panting breaths, her face a fiery red, sweat dripping down her flushed neck, a beaming smile breaking through her embarrassment.
She looked at Kota, her voice breathy, laced with a mix of relief and lingering heat.
"Okay," she panted, "That was… weirdly hot."
Kota's expression didn't shift, his focus turning to Aika, his voice flat but commanding.
"You're next"
