The walls swelled outward with a slick, sultry inhale, their fleshy pink surface glistening like skin after a forbidden touch.
Something warm and syrupy dripped from overhead, splattering onto Yuri's bare shoulder, sliding down her collarbone toward the swell of her chest.
"AA!" She screamed, swiping at it, her fingers smearing the slick fluid—only for a second, thicker drip to land in her hair, clinging like liquid sin.
Aika stepped back instinctively, her heels clicking, and the wall behind her shuddered, a low moan vibrating through the stone.
Her skirt hugged her hips tighter in the humid air, pantyhose shimmering with faint beads of moisture.
"Do not touch anything!" she barked, her voice sharp but trembling with the dungeon's pulse.
The corridor quivered again, a deep, unmistakably erotic moan rolling from the stone itself—like the dungeon was alive, aroused, and hungry.
The air grew thicker, musky, wrapping around them like a lover's breath.
"The walls," Kota muttered, backing into the group's center, his hoodie sticking to his skin, outlining his lanky frame.
"They're lined with Pleasure Stone. It reacts to movement and fear—and it craves it."
"I swear to God, if you say one more game word—" Reina snapped, her blouse clinging to her curves, the top button straining as her chest heaved with anger.
"I'm serious! This is the tutorial zone of Carnal Labyrinth EX!" Kota's voice rose, cracking under the swelling panic.
His eyes darted across the girls, catching glimpses of damp skirts and flushed skin. "Everything here is designed to teach you how to play with arousal mechanics. Look!"
He pointed at a glowing sigil on the wall—heart-shaped, pulsing with a wet, rhythmic throb, ringed by ancient moan-glyphs that seemed to writhe.
"That's a Cum Sigil. Touch it and you trigger a full-body binding trap. It drains stamina through induced orgasm. I watched people die in-game when they got too cocky here."
"No one is dying," Aika said sharply, her glasses fogging slightly in the heat, lips parted as she turned to the group.
"We stick together, we move slowly, and we ignore whatever he's rambling—"
"Don't ignore me!" Kota shouted, louder than he meant to, his voice echoing off the pulsing walls.
It silenced them all.
Even Reina, arms folded under her full breasts, narrowed her violet eyes and stayed silent, her thigh-highs glistening with dungeon dew.
Then something screeched—a wet, obscene scraping from the ceiling above.
Every head tilted up, eyes wide.
From the fleshy wall, a tendril descended.
Long, slick, and glossy, it glistened with a sheen that screamed touch me.
Its bulbous tip twitched, parting to reveal what looked disturbingly like plump, quivering lips, dripping with clear fluid.
"Oh my God, what is that—?" Miki whimpered, grabbing Reina's arm, her tanned cleavage bouncing as she pressed closer, her lollipop forgotten, lips parted in a glossy pout.
"It's a Tutorial Tendril," Kota said, his voice low, eyes locked on the writhing thing.
"If no one orgasms in the next five minutes, it picks one of us at random."
A pause, heavy with the dungeon's humid pulse.
The bulb licked the air, its lips parting with a soft, wet smack.
"No one's doing anything sexual in front of you," Yuri spat, her shirt now translucent with sweat, clinging to her curves like a second skin, nipples faintly visible.
Kota pointed behind her, his finger trembling.
"Then you better tell it that."
A second tendril had emerged, curling from the ceiling, its glossy length sliding across the stone with a slow, teasing caress, dripping onto the floor.
The glyph under their feet flared again, its lewd floral slit glowing brighter, pulsing in time with the dungeon's moans.
And one of the girls stepped forward—
"Rina, STOP!" Kota shouted, his voice desperate, sweat beading on his brow as the heat pressed against him.
She turned, her innocent face twisted with contempt, her blouse half-unbuttoned, revealing a glimpse of lacy bra. "This isn't funny, virgin-boy. You think you're going to get off watching us freak out? Go jack off in the corner."
Then she placed her hand on the glowing sigil.
The glyph flared, a burst of violet light bathing her in an obscene glow.
Runes ignited in a circle around her, pulsing like a heartbeat.
Her body jerked, eyes widening, lips parting in a gasp.
"No—!" Kota lunged forward, his sneakers slipping on the slick floor.
But magical hands—luminous, spectral, veined with glowing tendrils—erupted from the sigil and seized her.
"What the fuck is this. Help! HEL— Ahn!~" Rina screamed, not in pain but in raw, involuntary pleasure, her voice high and shrill, echoing through the corridor.
Her clothes burned away in flashes of violet light, leaving her bare, skin glistening as ethereal ropes bound her limbs, spreading them wide in the air.
Her moans grew louder, desperate, humiliating, her body spasming with each pulse of the sigil's magic.
Her eyes rolled back, hips bucking against invisible forces, a final, long cry tearing from her throat as she climaxed—again and again—until she vanished into a burst of light.
Even the dungeon seemed to quiet, as if sated, its walls pulsing softly, content.
Miki's mouth hung open, her lollipop dangling from her lips, eyes wide with shock.
Reina stood frozen, her skirt riding up from the tension, exposing more of her thigh-highs.
Aika's gaze was locked on the empty floor where Rina had been, her glasses slipping down her nose, lips trembling.
"I told you," Kota said, chest heaving, his voice barely above a whisper as the dungeon's heat pressed against him.
"I told you not to touch the sigils."
