The moment Kanae pulled the lever, the air changed, thick with a musky, electric charge that clung to the skin like a lover's breath.
A sharp click echoed overhead, followed by a deep, humming vibration from the floor, the chrome-plated walls shimmering with a lewd, reflective glow.
The door they'd entered through shimmered—then vanished into the wall like a sated sigh, sealing them in.
A low chime rang out, teasing and cruel.
"Kink Trial Initialized," purred a smooth, sultry female voice, dripping with sadistic delight.
"Scanning user profile… Synchronizing subconscious arousal index… Compiling core repressed fantasies…"
Kanae's smirk slipped, her blouse clinging to her curves, outlining her hardened nipples, her skirt riding up to flash soaked panties, her toned thighs glistening in the purple light.
"What the hell?" she muttered, her voice trembling, her manicured hand still gripping the lever.
The floor beneath her flared with a glowing circle, its intricate arcane lines stretching like a spiderweb, pulsing with a warm, tingling energy that encircled the entire party.
"Group immobilization commencing."
The girls staggered as golden light coiled around their ankles and wrists, its touch warm and teasing, like silken ropes.
Miki gasped, frozen mid-step, her gym shirt translucent, nipples visible through the damp fabric, her bloomers squishing audibly.
Reina swore, straining to raise her arm, her thigh-highs slipping to expose creamy thighs, her blouse clinging to her heaving breasts.
Yuri let out a startled yelp as her knees locked, her blouse riding up to reveal a sliver of midriff, her lacy bra shimmering with lube residue.
Aika's pantyhose gleamed, her glasses fogging, her hands clenched as the light bound her.
Only Kota remained untouched, his hoodie damp, outlining his lanky frame, his pants tight from the dungeon's musky heat.
He blinked, his pulse racing.
Of course.
The system recognized him as the Dungeon Navigator—non-participant, observer.
Just like the game.
The one who watches the chaos unfold.
"Target identified — Kanae Mitsui. Compatibility Ratio — 12%. Assigned Trial — Anal Degradation Play."
Kanae's face went blank, her flushed cheeks draining of color, her lips parting in shock.
"What."
Reina's violet eyes widened, her thighs twitching, her soaked skirt clinging to her hips.
Miki made a tiny choking noise, her tanned skin flushed, her breasts heaving against the golden restraints.
Yuri whispered, "Wait—what did it say?" her voice trembling, her blouse clinging to her curves, midriff exposed.
Even Aika—cool, controlled Aika—murmured, "Oh no," her glasses fogging further, her pantyhose shimmering as she strained against the light.
Kanae stood frozen in the summoning ring, her fists balled tight, her blouse clinging obscenely, outlining every curve, her skirt flipped up to flash more of her glistening thighs.
"That's a joke, right?" she hissed, her voice cracking, her body trembling.
"That's not even one of my—who the hell wrote this algorithm!?"
Kota took a slow step forward, his voice low, sweat beading on his brow as the dungeon's heat pressed against him.
"Kanae," he said quietly, "Don't panic. Listen to me. You can still survive this if you cooperate."
A low whirring noise started, the room's chrome walls reflecting their flushed, bound forms.
From the center, a mechanical pedestal rose—smooth, metallic, its surface slick with a faint, oily sheen.
As it extended, the top unfolded like a lewd mechanical flower, revealing a throne for sex punishment.
Sleek, black, shaped to hold someone on their knees—hips raised, arms back—with a pulsing, thick rod of glowing magical crystal at the center.
Runes spiraled up its shaft, throbbing with a soft, obscene hum, the base emitting waves of tantalizing heat.
It throbbed visibly, dripping with a faint, glistening fluid.
"User has thirty seconds to initiate voluntary mounting," the voice intoned, its tone sultry and commanding.
"Voluntary participation reduces pain and maximizes sensory compatibility. Countdown begins now."
Kanae stumbled backward, her heels skidding on the slick floor, her blouse clinging tighter, her panties soaked and visible through her skirt.
"No. No fucking way. You're all seeing this, right?!" she gasped, her voice breaking, her thighs trembling.
No one moved.
No one could, their bodies bound by the golden light, their breaths hitching in the musky air.
Yuri's eyes were huge, her blouse translucent, outlining her lacy bra, her skin glistening.
Miki looked like she was about to cry, her bloomers squishing as she strained.
Reina's gaze locked on Kanae, her breasts heaving against the restraints, her face flushed with a mix of fury and fear.
Kota stepped closer, his voice urgent, his pants tightening further as the dungeon's heat intensified.
"You need to mount it. If you do it willingly, it'll stop after a fixed threshold. If you don't, it'll activate automatically. Forcefully. You won't survive."
Kanae turned to him, something ugly twisting in her expression, her flushed face glowing in the purple light.
"Is this what you wanted? Huh? Me—bent over, begging for it while you give fucking commands?"
Kota didn't blink, his gaze steady despite the heat pooling in his core. "No. But it's the only way you live now."
"Ten seconds," the voice purred, the pedestal glowing brighter, its crystal rod pulsing faster, dripping more fluid.
Kanae took one step back, then another, her heels skidding across the floor, the summoning circle shimmering with lewd light.
"I'm not some bitch in heat!" she screamed, her voice cracking, her body trembling with humiliated fury. "I'm not going out like that—!"
"Five seconds."
Kota raised a hand, his voice desperate. "Kanae, please—"
"Fuck you!" she screamed, her blouse ripping slightly at the shoulder, revealing more of her glistening skin.
"Consent not detected," the voice intoned, cold and final.
"Auto-mount engaged."
