The chamber dimmed, its crimson glow pulsing a menacing red.
The translucent display above the rune pedestal flared, its text searing with cold, sadistic authority.
Timer expired.
Stimulation not detected.
Drain level: Tier One activated.
The concentric rings of glowing red runes ignited like molten fire, their etched symbols—hands, mouths, curves, and more intimate shapes—blazing across the polished stone floor, the chamber's pulse surging with cruel intent.
The stamina siphon roared to life, a sharp, visceral pull clawing at the party's nerves, draining their vitality with a relentless, erotic tug.
Everyone staggered, the game's insidious grip tightening.
Yuri gasped, dropping to one knee, her lacy blouse clinging to her flushed chest, a bead of sweat tracing her quivering cleavage as she clutched her ribs, her breath ragged.
"I—I can't breathe right," she hissed, her voice trembling, "It's pulling everything out of me—!"
Reina swayed, her violet eyes narrowing, a soft moan escaping her parted lips as her lacy skirt rode up, revealing flushed thighs trembling under the drain's pull.
Miki whimpered, her knees buckling, her shorts damp with lube, a flush creeping up her flushed collarbone as she braced her hands on the floor.
Aika braced against the slick stone wall, her glasses fogging, lips parted in a sharp gasp, her flushed neck glistening as her chest rose too fast, fighting the game's relentless assault.
Only Hina stood tall at the chamber's edge, arms crossed, her athletic frame rigid, her flushed features etched with defiance, lube-slicked boots planted firmly despite the drain's tug.
"Still think I should fake moaning?" she snapped, her voice sharp, a bead of sweat betraying her tension as she glared at Kota.
Kota gritted his teeth, his hoodie damp with sweat, eyes darting across the runes, their glowing shapes pulsing with obscene intent—small engravings of body parts, each a key to the game's perverse puzzle.
His voice cut through the musky haze, urgent. "Don't touch anything."
Then Miki tripped, collapsing forward with a soft cry, her hand splaying across a rune etched with a delicate, circular spiral.
The rune pulsed, its glow flaring white, a warm, electric surge coursing through her palm, her body stilling instantly, the drain's pull halting.
Miki blinked, her flushed cheeks wide-eyed, sweat dripping down her flushed temple. "…It stopped."
"What?" Aika gasped, her breath hitching, her flushed neck quivering as she leaned against the wall.
"My energy—" Miki looked up at Kota, her voice shaky with relief, her lube-dampened shorts clinging to her curves, "It stopped draining."
Kota's mind snapped into focus, the game's interface prickling with clarity.
"It's interactive," he muttered, his eyes tracing the spiral rune, its glow syncing with Miki's touch. "These runes—if you stimulate them, they push energy back into you."
Yuri raised her head, her flushed cleavage rising with a labored breath, her eyes glinting with reluctant understanding. "So we're supposed to…?"
"Touch the right glyph," Kota said, his voice firm, scanning the floor's symbols—curves, hands, mouths, and more intimate shapes. "The one that matches what you're doing. The system reads it."
The display flared again, its text pulsing with lascivious command.
Trial Stage: Circle of Stimulation
Participants must maintain contact with pleasure glyphs
Linked pulse detection commencing…
Kota turned to the others, his gaze steady in the chamber's sweltering haze, sweat beading on his brow.
"Pick a rune. Start now. Or collapse."
Miki pressed her fingers back to the spiral rune, its etched lines pulsing a soft pink beneath her touch, a warm, electric surge coursing through her palm, halting the stamina drain with a sultry thrum.
She moaned softly, her flushed cheeks glowing in the chamber's crimson haze, her lube-dampened shorts clinging to her curves, a bead of sweat tracing her flushed collarbone as her thighs quivered, the game's lust mana syncing with her rhythmic strokes.
Yuri, still kneeling, crawled to a nearby glyph shaped like parted lips, its red glow flaring under her gaze.
She hesitated, her lacy blouse riding up to bare a flushed midriff, then pressed her palm against the rune, her other hand stroking her inner thigh with a slow, teasing glide, the lube's scalding warmth igniting her nerves.
Her breathing evened, a soft gasp escaping her parted lips as the drain eased, her flushed cleavage rising steadily.
"Unreal," she muttered, her voice husky, eyes glinting in the musky air.
Aika didn't move, her posture rigid against the slick stone wall, her glasses fogging faintly, a bead of sweat dripping down her flushed neck as the drain tugged at her core, her legs trembling under the game's relentless pull.
Reina stared at the rune beneath her, an abstract V with a hovering circle, its glow pulsing with obscene intent.
"I think this one… matches," she said reluctantly, her voice low, a flush creeping up her jaw as she adjusted her lacy skirt, revealing lube-slicked thighs glistening in the crimson light.
Kota knelt beside her, his hoodie damp with sweat, eyes scanning the rune's glowing pulse, the game's interface prickling with the trial's stakes.
"No, not quite," he said, his voice calm but firm. "Your knees are too far apart. It won't read your contact right."
"I'm not going to—" Reina began, her violet eyes flashing, but Kota cut her off, reaching out with a gentle yet unyielding touch, his hands pressing her flushed thighs into alignment with the rune's narrow V, the lube's warmth seeping through his fingers, sending a jolt through her trembling skin.
Her breath hitched, a sharp gasp escaping her lips, her flushed face blazing under the chamber's glow.
"Now," Kota said calmly, unfazed, "Use your fingers, two knuckles down. Let me position—"
He didn't ask permission, taking her wrist with a steady grip, angling her hand until her fingers brushed her slick folds beneath her panties, the lube amplifying each touch with an electric, teasing pulse.
Reina gasped, her body tensing, a soft moan stifled in her throat.
"You—!" she hissed, her eyes wide with humiliated fury.
"You'll collapse if you don't," Kota murmured, his gaze locked on hers, his touch lingering just long enough to guide her fingers into a slow, rhythmic glide, the rune flaring beneath her with a sultry glow as her contact synced.
Reina clenched her jaw, her flushed thighs quivering, then began moving her hand on her own, her fingers circling her core with a lube-slicked intensity, each stroke drawing a tighter clench, her suppressed moans echoing off the chamber's slick walls.
The rune glowed brighter, its pulse stabilizing her energy, the drain's pull easing.
Yuri watched from her glyph, her sharp eyes glinting, her palm stroking the lip-shaped rune in sync with her thigh's slow caress, her flushed midriff shimmering with sweat.
Miki was half-lost in her spiral rune's rhythm, her lips parted, soft moans spilling as her fingers pressed deeper, her flushed collarbone quivering under the game's perverse pull.
Aika wavered, her legs shaking harder, her flushed neck glistening as she resisted, her breath ragged, the drain intensifying its grip.
