Asmodeus stared at the lewd opening twitching beneath Lumina’s lifted hips.

Thin strands of translucent silk stretched between the soft folds every time it clenched, glistening beneath the pale moonlight spilling through the balcony. The sight alone made his cock jerk violently against his stomach.

"Damn..." His fingers dug deeper into her hips. "You really went this far because you’re jealous?"

Lumina buried her face deeper into the quilt.

"N-No..." Her spider legs twitched anxiously behind her. "Maybe a little..."

"Heh."

He dragged two fingers through the dark pink slit slowly.

A sticky strand immediately stretched between his fingertips.

Lumina shuddered.

"Hmmn~!"

"So sensitive already?" He mused, spreading the opening wider with his thumb. "I haven’t even started yet."

The fake pussy clenched instinctively around nothing.

Its inner walls flexed and pulsed softly, leaking more slippery webbing onto his hand as if begging for attention. The obscene sight made his breathing heavier.

’This little pervert seriously reshaped her spinnerette for me...’

"Baby..." She whimpered softly before correcting herself almost instantly. "A-Asmodeus..."

"Mhm?"

"Don’t stare so much..." Her voice trembled. "It’s embarrassing..."

"But you spread all three holes open yourself."

"T-That’s different!"

He chuckled deeply before suddenly leaning forward.

Lumina gasped when his tongue slowly dragged across her spinnerette in slow, unfocused circles. A long, sticky thread stretched between his mouth and her trembling opening before he found a small, tiny bud, resembling a clitoris.

"Hah?!"

Her entire body jolted.

The black arachnid limbs behind her spasmed wildly, stabbing against the sheets while her pussy leaked a fresh stream onto the blankets below.

"Asmodeus!"

He chuckled, drawing back with her sticky fluids dripping from the tip of his tongue, before he gulped them down.

"Tastes sweeter than I expected."

He licked it again deliberately.

His tongue flicked along the dark slit slowly, with a thorough pattern, curling through the silky folds oozing with sweet fluid.

The muscles in Lumina’s thighs immediately weakened.

"Mmmn... ah... ahhn..."

Her hips tried to crawl backwards, desperate for more friction, but his large hands held her firmly in place.

"What happened to all that confidence earlier?" He teased. "You were acting pretty bold a minute ago."

Lumina turned her head away, her long silver hair spilling across the sheets while her voice shrank into an embarrassed whisper.

"Y-You started licking it immediately... how am I supposed to stay calm...?"

"Hah."

His cock twitched painfully beneath him.

The veins pulsed with fresh blood, swelling the bulbous head further.

Watching her usually mature and teasing personality crumble this quickly was absurdly erotic.

Especially when all eight of her red eyes had already become hazy with lust.

"Asmodeus..." Her voice softened again. "Does it really turn you on that much?"

Instead of answering, he dragged the swollen tip of his cock between her soaked folds, gripping his base tightly.

First her pussy.

Then her asshole.

Finally, the new opening she made solely for him.

Each pass coated his shaft with a mixture of slippery fluids and sticky silk.

Lumina’s breathing immediately lost rhythm.

"Nn... ah... wait..."

The thick head pressed against her spinnerette slowly.

Lumina’s head flung back, drool spilling from the corners of her lips as her mouth gaped open wide like her cunt.

Her entire body tightened.

Even her spider limbs curled inward anxiously.

"Relax." His voice lowered beside her ear. "You wanted this, didn’t you?"

He could feel the warm pulse of her heart through his cock as her wet walls clung to his tip.

"I-I did but..." She bit her lip hard enough to leave marks. "It’s my first time using this form properly..."

He kissed the back of her shoulder once, before slowly pushing inside.

Lumina cried out the instant the thick tip breached her new opening. A lewd pop sounded the moment his glans reshaped her insides to match his cock.

"Ahhnn—!"

Her entire body curled up violently as if she were a dying spider.

The spinnerette clenched around him with terrifying strength, sticky inner walls spasming and milking his cock before he had even pushed halfway inside. A soft row of bumps wrapped around him like a ring of mouths.

They puckered gently against his foreskin.

’Fuck it’s like I’m getting multiple blowjobs...’ He grunted while jerking his hips.

"Asmodeus...!" Her voice broke into a breathless moan. "W-Wait... it’s squeezing—"

"I can feel it."

His teeth ground together, desperately enduring his near climax.

The sensation was absurd.

Unlike her pussy, which felt soft and wet, this hole curved in strange places, while pulsing and tightening section by section as though it were trying to drag him deeper inside by force. Thick silk clung to his shaft each time he moved, stretching in translucent strands between their bodies.

"Damn..." He exhaled roughly. "This really does feel different."

Lumina whimpered proudly into the sheets.

"Mhm... I told you..." Her hips trembled beneath his hands. "I made it specially for you..."

He pushed deeper, and she gasped as if he squeezed her throat.

Lumina’s limbs spasmed beneath him as spurts of fluid sprayed from just above her pussy, staining the bed with a slight ammonia scent.

Slowly.

The swollen head spread her inner walls apart inch by inch while sticky webbing coated the underside of his cock. Every movement produced a wet, lewd drag that echoed faintly through the dark bedroom.

Lumina’s thighs shook harder.

Her pussy clenched around nothing beneath her while droplets of pure arousal soaked the golden sheets.

"Ahn... ah... too deep already..."

"You were the one teasing me earlier." He smirked, leaning over her back. "What happened to all that confidence?"

"T-This feels too good..." Her voice cracked helplessly. "How am I supposed to think properly...?"

Her voice twisted into a pleasant squeal the moment his cock finally bottomed out. The moment his hips pressed flush against her rear, the spinnerette suddenly tightened all at once.

The pressure inside almost crushed his cock.

Before a warm flow of gushing threads leaked like a flood.

"Hrk—!"

A rough grunt escaped his throat.

The pressure around his cock intensified repeatedly, rhythmic contractions gripping his shaft almost like a second heartbeat. At the same time, thin strands of silk continued forming inside, wrapping around him each time Lumina’s body twitched.

’What the hell...’

It almost felt like she was trying to keep him inside permanently.

Lumina looked back over her shoulder, her cheeks flushed and her eyes watery.

"I-I can’t control it..." she admitted between uneven breaths. "My body keeps reacting to your scent..."

"Heh... so this little hole really was made to trap me."

"Nn..." Her eyes darted away shyly. "Maybe..."

His restraint snapped.

Asmodeus suddenly pulled her hips backwards while thrusting forward at the same time.

Plap!

"Aahhhhn~!"

The entire bed shook violently.

Silk strands snapped between their bodies while Lumina’s moan echoed throughout the chamber. Her spider limbs stabbed into the mattress for support as he dragged nearly all the way out before slamming back inside again.

Plap! Plap! Plap!

"Ahh~ Haaaaah....♡ Hnnnngh.... Asmodeus.... Slower! ♡ Ahhhnnn!"

He glanced down as she began to slam her buttocks against his thighs, seeking more penetration and force.

"You don’t sound like you want slower."

Her new opening greedily swallowed his cock with every single thrust.

The tighter Lumina became, the rougher his movements grew.

Soon, the room filled with wet squelching, desperate gasps, snapping silk, and the obscene sight of Lumina’s body trembling every time his hips crashed against her from behind.

Her voice rose sharply.

The spinnerette clenched far harder than before.

A thick strand of webbing burst from the opening around his cock.

Squelch~

"Asmodeus~~ ♡♡ Asmodeus ♡ Asmodeusss.... Nggh....!"

Another thick strand shot from Lumina’s spinnerette, wrapping around his shaft while the walls inside her convulsed uncontrollably.

Plap! Plap! Plap!

His hips slammed harder into her trembling body.

The entire bed creaked violently beneath them, golden sheets twisted and soaked, while translucent silk stuck to both their skin.

Moonlight shimmered across Lumina’s back, illuminating the way her body shook every single time he buried himself to the base.

"Y-You’re going too deep... ahhnn~!"

Her voice dissolved into broken moans.

Yet instead of escaping, Lumina pushed herself backwards desperately, grinding her hips against him whenever he pulled out slightly.

The sensation nearly drove him insane.

Her spinnerette was already unbearably tight, but every orgasmic twitch made the inner walls squeeze harder around his cock, milking him relentlessly while sticky webbing coated his length layer after layer.

"Hah... Lumina..." His breathing roughened sharply. "Your body’s trying way too hard to keep me inside."

"T-That’s because..." She gasped into the sheets. "Because your cock feels too good..."

Her pussy clenched emptily beneath her.

Even her asshole fluttered every time his shaft bullied its way back into the lewd fake pussy she created solely for him.

"Asmodeus...!" She looked back at him again, eyes watery and unfocused. "I think I’m going to....!?"

Before she could finish, he suddenly grabbed both her wrists and pinned her chest against the mattress.

Plap! Plap! Plap! Plap!

"Aahhhhnn?!"

His thrusts became brutal.

Fast, heavy and completely inhuman.

The thick head of his cock repeatedly slammed against the deepest parts of her spinnerette while silk snapped wildly between their bodies.

Lumina’s mind went blank almost instantly.

Her spider limbs curled inward helplessly while obscene moans spilt from her lips one after another.

"Asmodeus! Asmodeus... ah! Ahhnn~! ♡ I’m cumming...!"

The spinnerette suddenly clamped down with crushing force.

That was enough to break the last thread of restraint inside him.

"Damn it...!"

He shoved the tip of his cock straight inside her trembling ass and erupted violently.

Hot seed flooded deep into the wrinkled opening in heavy bursts.

Lumina cried his name breathlessly.

Her entire body spasmed beneath him as her asshole greedily guzzled every pulse from his cock, twitching and flexing as though refusing to let even a single drop escape.

"Hahh... hah..."

Asmodeus lowered himself over her shaking body slowly, both breathing heavily while strands of silk and cum stretched obscenely between them.

Then Lumina weakly turned her flushed face toward him.

"...Mhm." She smiled dizzily. "I win."
