Aika knelt slowly onto the slick, rune-etched floor of the chamber, her movement not surrender but a calculated necessity, biting her lip as she positioned herself over a glyph carved with dual lines curving inward, its red glow pulsing with obscene intent.
Her hands pressed down, the lube's scalding warmth seeping into her palms, a flush creeping up her flushed neck, her glasses fogging faintly in the musky, arousal-charged air thick with lavender and raw heat.
The rune pulsed pink, faint and unsteady, her brow furrowing as the game's stamina drain tugged at her core.
Kota approached, his hoodie damp with sweat, his voice calm but firm.
"You're tense," he said, kneeling beside her, the chamber's crimson glow casting shadows across his sweat-beaded brow.
"I'm not putting on a performance," Aika muttered, her eyes narrowing, a bead of sweat tracing her flushed collarbone, her skirt clinging to her hips.
"You won't need to," Kota replied, his gaze steady, undeterred by her defiance.
Aika stiffened as his hand reached under her skirt, her breath hitching, but he didn't grab—instead, his two fingers pressed gently against her inner thigh, nudging it open with a warm, electric touch, the lube amplifying the sensation.
He took her hand, as he had with Reina, guiding it forward to her lacy panties, damp with lube, his fingers brushing hers as he positioned them over her slick folds.
"Slow," he murmured, his voice a low command. "You don't have to moan. Just move. Match the rune."
Aika followed, her hand trembling, soft strokes gliding over her damp skin, the lube's heat igniting her nerves with a teasing pulse.
The rune flared, glowing pink, then white, its pulse syncing with her rhythm, a shuddering exhale escaping her parted lips, her flushed thighs quivering as she avoided Kota's gaze, her glasses slipping down her nose in the musky haze.
Behind them, Miki had resumed her pace on her spiral rune, her fingers circling with a lube-slicked rhythm, soft whimpers spilling every few seconds, her flushed cheeks glowing, sweat dripping down her flushed midriff as her shorts clung obscenely to her curves.
Reina, one eye shut, bit down on her sleeve to muffle her moans, her lacy skirt hiked to bare lube-slicked thighs, her fingers stroking her rune's V-shape with a tense, controlled cadence, her flushed jaw clenched.
Yuri stroked her lip-shaped rune slower, her lacy blouse baring a flushed cleavage, her eyes sharp and suspicious, fixed on Kota's every move, a soft gasp betraying her rhythmic thigh caress.
Hina remained untouched, a statue against the chamber's wall, arms folded, her flushed features cold with defiance, lube-slicked boots planted firmly, her voice cutting through the musky air.
"Enjoy your puppet show," she spat, sweat tracing her flushed temple, her thighs clenching against the drain's pull.
The room glowed brighter, the rune rings pulsing in offset harmony, the girls' moans weaving a tense, electric symphony as the game's lust mana surged.
The central display flared.
Phase 1 Sync Achieved
Prepare for Tier 2: Linked Interaction
The girls froze, their breaths ragged in the sweltering haze.
"Linked?" Reina rasped, her flushed jaw tightening, her sleeve still caught between her teeth.
Kota looked up at the display, its text shimmering with cruel intent:
Begin partner-based stimulation.
Energy drain will resume if physical contact is not initiated in 30 seconds.
Miki whimpered, her flushed midriff quivering, her fingers pausing on her rune.
"…We have to do it to each other now?"
Kota sighed, his voice heavy with resignation. "Here we go again."
Miki and Reina stared at each other, disbelief etched in their flushed faces, Reina's sweat-soaked hair clinging to her cheek.
The energy dipped, the rune rings darkening, a heavier pulse clawing at their nerves.
Warning: Linked Arousal not detected.
Draining Resumes in 20 seconds.
"Okay," Kota said, stepping forward, his tone sharp.
"We pair up. Now." He grabbed Miki's shoulder, guiding her to face Reina, his hands firm but precise. "You, hands on her hips. You, guide her rhythm. Touch there—no, lower. Slower."
Reina bristled, her flushed thighs tensing. "You're ordering me to—"
"Do it or collapse," Kota snapped, his gaze unrelenting.
Reina obeyed, her hands settling on Miki's hips, guiding her rune strokes with a slow, lube-slicked rhythm, their motions syncing as the floor pulsed soft white light beneath them, moans spilling in harmony, the game's energy stabilizing.
Kota turned to Aika, still kneeling, her hand frozen, her flushed neck glistening, her eyes wide with defiance.
"I'm not going to make out with a student," she said, deadpan, her voice strained.
"You're not," Kota said, stepping closer, his voice calm but commanding. "You're going to let me do it."
He cupped her breast, not hard, not groping, but a guiding hold, his thumb brushing under her bra strap, easing it aside to bare her flushed skin, matching her ragged breathing with a slow, teasing stroke, the lube's warmth amplifying each touch.
Aika shuddered visibly, a sharp gasp escaping her lips, her flushed thighs clenching as the rune beneath her flared like fire, its white glow syncing with her quickening pulse.
Yuri watched, her hand slow between her thighs, her flushed cleavage rising, her sharp eyes never leaving Kota, suspicion smoldering in their depths.
The circle flashed white, the runes blazing as the girls' synchronized moans echoed, the chamber's walls throbbing with sated approval.
The display updated.
Circle Phase Complete.
Deeper Runes Unlocked.
Beneath the glowing floor, a new ring of violet glyphs ignited, their twisting patterns pulsing with unforgiving intent, the game's sadistic mechanics escalating.
Kota exhaled, his hand still on Aika's chest, sweat dripping down his brow.
"…We're not even halfway done."
