Cold grass cradled his cheek.
He blinked, vision swimming, the smell of loam and dew thick in the air. The world was too bright, the sky a bleeding watercolor of orange and silver, clouds shifting like restless beasts. He pushed himself upright, breath ragged.
"Where… am I?"
His voice sounded foreign to his own ears.
He wasn't in his room.He wasn't on Earth at all.
When he stood, the world felt different — lighter, sharper. His body felt stronger, leaner. And then a faint tone chimed in his skull, cold and smooth.
[System Online]
Welcome, Host.

Unique Ability: Tentacle Manifestation
Directive: Survive. Grow. Feed.
He froze.
"…Tentacle what?"
A diagram blinked into view. It showed black, liquid-like appendages sprouting from the lower back, shifting like living shadow.
Before he could even react, he felt something inside him stir — deep along his spine.Instinct moved before thought.
Something uncoiled from him with a soft shhhlick.
A black tendril slid from his back and swayed in the air like a curious snake.He yelped, stumbling backward, landing on his ass.
"Holy—! That's— That's mine?!"
The thing curled at his voice, tilting almost playfully. Its surface shimmered faintly, slick and warm. When he touched it, sensation rippled through his nerves like static down his spine. He gasped.
It was him.
He could move it. Feel it. Like a third arm—except more… alive.
Another chime.

He blinked. "...Aroused lifeforms? Like—sex?"
Silence answered. The System didn't care if he understood.
He walked for hours, barefoot through tall silvergrass until the trees thinned into a dirt road.Smoke curled above the hills.A tavern sat at the edge of a little village, lanterns glowing soft amber.
Hunger gnawed his belly.Curiosity gnawed harder.
He slipped inside.
The tavern was warm and buzzing. Laughter. Clinking mugs. A few merchants at the bar, two women playing dice in the corner booth. Both were older than him—maybe late twenties—but their skin was flawless, their hair shining in the hearthlight. Their laughter was smooth wine.
And… they looked in their twenties. Just like the System said—this world's people stayed young after thirty.
He sat two tables away, heart thudding.
His gaze kept sliding back to them: the dark-haired one lounging with her boots on the seat, the redhead leaning forward, neckline plunging scandalously.
A new thought burned quietly through him:
Could he…?
The tentacle stirred inside him, reacting to the thought, a pulse of heat sliding along his spine.
He swallowed hard.This was insane. He couldn't.
But he wanted to know.
He let the tavern noise cover him, then exhaled slowly.
A shadow slid from beneath his chair.
It coiled across the floor, silent as breath, crawling under the edge of their booth. They didn't notice—their laughter covered the faint brush of movement.
The tendril rose between their legs like a whisper.
The redhead jumped just slightly, hips twitching. She frowned, shifting her chair.The tentacle slipped away—then stroked up her calf again, slower.
She blinked. Bit her lip.
The dark-haired one kept laughing, oblivious—until a second tentacle slid out of him, splitting off, and wrapped around her ankle under the table.
His breath hitched.Two at once—he hadn't even known he could.
The redhead pressed her thighs together, a tiny shiver running through her. The dark-haired woman went quiet mid-sentence, her eyes unfocused for half a second before she chuckled again, voice unsteady.
Heat raced through his spine. The tentacles were slick now, brushing higher. Up thighs. Soft. Teasing.
The redhead's breathing hitched. The dark-haired one dropped her dice.
Neither could see anything.
He watched from his seat, trembling, pulse hammering. His mind was screaming—Stop, stop, this is insane—but the sight of their shifting hips and flushed cheeks drowned it.
The tentacles slid under their skirts.
He felt it—their heat, the slick softness parting around his touch. His nerves lit up like firecrackers. The redhead bit down on a laugh, face crimson. The dark-haired one tilted her head back just slightly, lips parted, eyes dazed for a heartbeat.
A tone chimed in his skull.
[Lewd Energy +6]
His heart nearly stopped.
They twitched. Moaned faintly. One hand slipped between the redhead's thighs like she couldn't resist.
He panicked.
The tentacles yanked back into him in a snap of motion.
He sat frozen, drenched in sweat.
The women blinked, disoriented, then burst out laughing again, brushing it off as the wine.
His System glowed faintly.

[Skill Progress: Sensory Threads — 2%]
He swallowed.His body was shaking—not from fear, but from… something darker.
He had touched them.Felt them.Made them feel.
And they didn't even know.
