The south gate of the city was busier than Eren expected for that hour of the morning. Wagons creaked over packed gravel, pulled by draft beasts with dull eyes and sunken bellies.
Merchants shouted in hoarse voices, pushing wilted fruit, faded cloth, cracked clay pots. The air was an uncomfortable blend of damp smoke, fresh manure, and briny river stink.
Eren paused about thirty meters from the gate, squinting to adjust to the sudden brightness after hours in the wet forest gloom.
Behind him, Nyssa stumbled over a tuft of dry grass, nearly falling. A wet, embarrassed noise escaped her gelatinous lips as she fought to stay upright. The makeshift leaf covering—already wilted and torn in multiple places—shifted badly over her naked body.
She tried to pull a larger leaf over her chest, covering only part of her full, firm breasts that kept slipping out at the sides. Her translucent blue skin didn't help: even when "covered," the outline of her nipples was visible, the tips hardened from the morning chill.
"Nnh... m-master..." she whimpered softly, trying to adjust the leaves. "I-it's... showing too much?"
Eren didn't respond immediately. He regarded her with an analytical, almost cruel look, head tilted slightly like a craftsman inspecting poorly-cut wood.
Insufficient covering. Planning failure. Result: exposure.
He sighed, thumb brushing over the scar on his palm—a fresh reminder of the blood pact that still ached.
City with guards. Merchants. Guild lookouts. Unnecessary attention.
She kept squirming in shame, those huge wet eyes full of anxious pleading. Her thick, translucent thighs gleamed in the light, the color shifting to greenish tones as she shrank back.
"M-master... isn't there another way?"
Eren's gaze shifted from her to the gate. He could already see guards in stained mail, holding short spears and yawning. But one of them was watching too closely. Not him—her.
The man raised an eyebrow, wrinkling his nose as he took in the voluptuous female figure awkwardly trying to cover herself with leaves.
Compromised discretion. Potential for approach.
Eren drew a slow breath, stepping toward the packed road.
"Come."
Nyssa scurried after him, bare feet making wet sounds on the hard earth.
schop schop schop
The leaves rustled against her gelatinous body. She bit her lower lip, clutching the makeshift "skirt" against her thighs.
As they neared the gate, the staring intensified.
A shirtless boy holding a basket of fish gawked openly at Nyssa, eyes wide. His mother yanked him away, muttering something about "don't stare at the witch."
Two guards exchanged a look. One scratched his chin, the metal of his helmet clicking against his teeth.
"What the hell is that?" he asked, not to Eren but his buddy.
The other shrugged.
"Some kind of slave?"
Nyssa shrank even more, whimpering softly.
"M-master... they're staring..."
Eren ignored her, but a vein throbbed in his neck.
Compromising exposure. Impossible to enter without adjustments.
As soon as they were through the gates, he turned sharply into a side alley, a narrow passage squeezed between cheap stone walls and old boards nailed any which way. The smell of dry piss and mildew greeted them like a welcome mat.
He didn't care.
"Stay here."
She froze, still trying to adjust the leaves that kept sliding off her body, leaving half her breasts exposed. Her face was a messy wash of liquid embarrassment.
"P-please, master... help me..."
He closed his eyes for a moment, then opened his inventory, rummaging through items from past missions—worm leather, venom glands, rat tails. He abandoned the idea of selling them at the tavern today. Too risky with her exposed.
Instead, he grabbed a few silver and gold coins.
Immediate liquidity. Short-term solution.
He looked at Nyssa again.
"Stay."
She nodded, pressing her thighs together.
Eren left the alley, his filthy cloak trailing behind him, and went straight to the market area.
Makeshift stalls jostled for space with rotting barrels. Merchants screamed prices while cursing at rivals.
He ignored the spoiled fruit and went straight to a used-clothing vendor. The man was fat, bald, and covered in warts.
"Cloth. Cheap. Big."
The man looked him up and down, then spat on the ground.
"Clothes or blanket?"
"I don't have time."
Eren tossed the coins on the counter.
The man picked up a filthy, fraying piece of linen.
"That's all I got. It'll stink after a while..."
Eren didn't thank him. He took the cloth and went back.
Nyssa was exactly where he'd left her, like a loyal dog—only far more embarrassed.
"M-master... I-I'm so ashamed..."
He tossed the cloth over her.
"Put it on."
She grabbed it in both hands, face lighting up in relief.
"T-thank you!"
The makeshift garment wasn't much. It was too short, showing off her thick thighs nearly to the crotch and squeezing her breasts so they threatened to spill out in certain poses. But at least it hid enough that no one could see explicit details.
When they emerged from the alley back onto the main street, the stares continued. But now they were less direct. More curious than shocked.
One merchant muttered to his friend:
"What the hell is that? Some exotic whore?"
Another answered:
"Must be a domesticated monster. Look at the form."
Nyssa bit her lip, eyes welling with tears.
"They... they're still staring..."
Eren ignored her.
Partial improvement. Still draws attention. But manageable.
He walked faster. Nyssa had to almost run to keep up, the fabric hiking up in places and revealing flashes of her translucent skin.
When they finally neared the central square, the slime stopped, panting, clutching the cloth tightly against her chest.
"Master... I'm sorry... I... I didn't mean to be a bother..."
He didn't answer. He just analyzed the situation with cold detachment.
I need a more discreet mission. A dungeon would do. Advanced enough and guaranteed to avoid attracting attention.
"Follow me, Nyssa."
────────── ⋆⋅☆⋅⋆ ──────────
The muddy evening wind pushed damp smoke against the low rooftops, carrying the stench of old fish, manure, and weary people. He walked in the shadows of those crooked houses with the same care a surgeon uses to hone a blade: steps calibrated not to creak on rotten boards or kick loose pebbles.
His hood drawn low hid his face, but his eyes were two dark blades moving without hurry. The filthy guild hall receded behind him, the cold voice of old Hagan still echoing in his bones.
"Keep your eyes open."
He didn't need reminding. He was built for this.
Elbows tucked in, breath shallow, every muscle trained since youth to obey without waste. He moved like a smudge of soot, always a step behind or to the side of his target—never directly behind to avoid easy counters.
Eren Vale.
A man with a dead expression, steps too firm for the soft mud. He carried the aura of someone who didn't care about anyone—not even himself.
And next to him... that thing.
At first, the assassin saw what everyone else did. Some exotic prostitute, bought off a desperate smuggler. Long, translucent legs trying to hide under cheap cloth that didn't really cover anything. Exaggerated, firm breasts bouncing under the linen. Wide hips, narrow waist, that awkward, self-conscious manner.
Too performative. Almost laughable.
He watched from an alley, eyes slicing the distance like old razors. The girl shrank in on herself, tugged the cloth up to cover her nipples. Whimpered. Her legs tangled in her own steps.
But she didn't tremble like a human.
She didn't sweat like a human.
The lamplight shone through her too much.
He pressed back against the damp wall, ignoring the sour reek of urine rising when the stone shifted. He focused on her, letting his brain stitch together data like a drunken tailor.
Translucent skin. Irregular shine. Movement too flexible. Wet sound in steps. Soft but self-repairing.
She slipped between people without really pushing them. Each time she stumbled, her body reshaped to avoid falling. A breast would escape but didn't squash like flesh—it rearranged like liquid held by a membrane.
When Eren Vale stopped to talk to her, the Executor observed the man's mouth move slowly. Minimal words. Cold. The girl reacted with near-canine devotion. Cried in shame. But never refused anything.
Total obedience. No sign of coercion. Absolute consent. The assassin felt the leather of his glove creak as he clenched his fist.
She was a monster. The slime in the shape of a woman.
Not just cheap fetish. Something rare. Useful. That's when he realized maybe Eren Vale wasn't so foolish after all. Pretending to be pathetic, dragging along some half-dead whore, when really he was hiding gold in plain sight.
He moved to another alley as the pair entered an improvised shop. Vaulted over a fallen barrel, knees silent in their bend. Slid like smoke through a gap between houses. His eyes tracked that patch of motion: cheap linen moving too much over impossible curves.
When they emerged, the woman was more covered but not better. She looked like a badly wrapped gift. Her thighs still gleamed in the orange lamplight, reflecting too much. He saw people wrinkling noses, pointing, whispering.
No prostitute would be so awkward. No woman raised in the city's brothels would be so terrified to show skin.
The shadow inhaled slowly, filling his lungs with the city's dirty air.
Inevitable conclusion. Transformed form. Humanoid slime.
High value. Unique.
The shadow moved with him. When Eren Vale finally turned the corner toward the larger square—probably headed for the guild—the Executor stopped following.
He didn't need to.
He already knew enough.
Clear report. Identity confirmed.Capture value: extreme.
He turned, his black cloak dragging a whisper against the filthy ground. Disappeared between two wagons, ignoring the drunken shout of a merchant who never saw him pass.
The shadow left no trace.
Information gathered.Now it was time to deliver it to the boss.
His steps vanished into the crowd, like smoke refusing to be contained.
────────── ⋆⋅☆⋅⋆ ──────────
The dungeon entrance was a wide crack in the rock, swallowed by thick roots that looked like skeletal fingers trying to seal the passage. The air there smelled of cold mold and trapped dampness, mixed with the heavy perfume of rotting leaves. A thin fog crawled along the gaping mouth of the tunnel, swirling in lazy spirals as the wind blew sideways.
Eren stopped about five meters away, eyes half-closed as he studied every detail.
Low-level dungeon, designed for training missions. Standard: scaled monsters. Boss at the core. Usually mapped, but with minor variations.
He adjusted the strap of his improvised pack on his shoulder, feeling the weight of herbs, worm hides, and a few coins stuffed in a wrinkled pouch.
Behind him, Nyssa shrank with the cheap cloth pressed to her body—now a little less torn but still leaving her curves exposed at awkward angles. Her translucent face darkened to a deeper green whenever she realized how little it covered.
"M-master... it's dark in there..."
Eren didn't answer immediately. Instead, he watched the weak morning light that no longer reached the entrance.
Zero illumination. Monsters with keen senses. Slime adaptable. Property: useful elasticity for surprise attacks.
"Let's go."
Nyssa bit her lip but followed with timid steps, the wet sound of her bare feet muffled by the moss.
The transition from light to darkness was abrupt. Within a few meters, the world became an irregular stone corridor. The floor was coated with a thin layer of slime that made every step risky. Roots along the walls seemed to move with the nonexistent wind.
Eren moved slowly, every breath calculated not to echo.
Trap pattern: slippery floor, impaired vision. No warning in the contract.
Nyssa trembled behind him, clutching the fabric over her bare breasts that shifted too much for so little cloth.
"M-master... are you sure...?"
He raised his hand, signaling silence.
The sound came first: dry scratches against the rock.
Then the shape: three thin creatures with elongated limbs, gray-green skin, and glassy eyes. They looked vaguely humanoid but with crooked spines and wide jaws.
Eren didn't retreat.
Ghoul variant. Medium physical strength. Attack pattern: frontal lunge with claws. Low intelligence.
He crouched, his body creaking. His right arm stretched with a grotesque elastic snap, joints rearranging in an inhuman way.
Nyssa let out a muffled squeak.
The ghouls snarled at once, advancing as a trio, claws raised.
First on the right with half-second delay. Vulnerable.
He twisted his torso, using the elasticity to whip his arm. His hand smashed the first ghoul's face hard enough to crush its crooked nose, sending its head slamming into the wall with a melon-cracking sound.
The second lunged from the side.
Predictable.
He let himself fall sideways onto the slippery mud, his arm stretching downward to grab the creature's ankle. The ghoul fell face-first onto the stone, its jaw breaking at an ugly angle.
The third leapt at him.
No defensive reaction mid-air.
Eren twisted his arm backward, forcing his shoulder to dislocate with a sickening pop. His hand caught the ghoul's neck and yanked, using its weight against the fall. Its head hit the ground and split with a wet crack.
Silence.
Only heavy breathing.
Nyssa was panting behind him, her wide, glowing eyes shining, the cloth now nearly falling off as she trembled.
He didn't look at her. He simply called the system with a thought.
[Loot Obtained]
- Ghoul Claw x6
- Ghoul Tooth x4
- Cursed Bone Fragment x2
- Rusted Bronze Coin x3
He inhaled deeply.
Low-value items. Useful for sale or low-tier crafting.
He turned to Nyssa.
"Come."
She approached with uncertain steps, clutching the cloth to her body. Her translucent breasts bounced and slipped free with every movement, and she panted as if she'd been running for hours.
He walked ahead, eyes adjusting to the darkness. More corridors, more slime. More scratching in the corners.
He faced other groups.
Two mutant rats—faster, but predictable. He sliced them in half with elastic attacks, dodging their exposed teeth.
A giant insect, hard-shelled. He used the elasticity to slip around its frontal attack and twisted its neck until it snapped.
Advanced elasticity: decisive factor.
Finally, they stopped before a large stone door, cracked in the middle, with nearly faded runes.
Eren watched in silence.
Boss mark. Contract requires elimination for full reward.
He exhaled, mentally pulling up the bond's status.
[Affinity: 78%]
He frowned.
Below 80%. Properties already degrading. Bond strength insufficient to face boss safely.
He looked at Nyssa. She was gasping, chest rising and falling, eyes wet, her body shining with cold sweat.
"M-master...?"
He didn't answer immediately. Just evaluated.
Defensive properties reduced. Elasticity less responsive. Submissiveness less reliable.
She shivered.
"Master... I... I know... what you're thinking..."
He arched an eyebrow. She bit her lower lip, the dark blush spreading over her translucent skin.
"I-it's a problem with the contract... isn't it...?"
He stayed cold.
"Yes."
She closed her eyes, took a deep breath, and nodded.
"I... I can... we can... do it again."
The words came out wet, low, almost a whisper.
"I... I want to help..."
Eren didn't answer immediately. He watched her as if she were a precious but flawed artifact.
Option confirmed. Need for high bond level for combat.
She opened her eyes.
"P-please, master... let me... help you…"
The truth was, the slime had wanted to have sex with him again for a while. But she hadn't gotten her master's permission. Besides, being so visibly exposed had left her more aroused than she could even imagine herself.
Eren took a deep breath. But he didn't speak. He just reached out, grabbing the dirty cloth that covered part of her and pulling it away slowly, already preparing for the pragmatic ritual to come.
He moved with the same brute force as before, his hips snapping in a heavy rhythm, without hesitation. Every thrust was a hard, dry impact against her translucent body, sending waves of wet, jelly-like flesh rippling.
Nyssa moaned loudly, her voice breaking in pleading, hoarse cries as her body molded to take him completely, trembling in chaotic spasms.
He kept total focus, jaw locked, eyes half-closed so he wouldn't get distracted by the begging moans. His hands gripped her wide, unstable hips tightly, pulling her into each thrust.
Nyssa whimpered in pure pleasure, mouth falling open in wet little cries, begging him not to stop.
Even so, the act ended quickly, almost mechanical—a rough rhythm that sought efficiency more than connection.
When Eren finally spilled inside her, exhaling with a low growl, Nyssa moaned in muffled ecstasy—but there was something frustrated in her wet eyes, as if she wanted more than that brutal effort.
That strange silence after their second sexual act was different from the first. Heavier, maybe more uncomfortable. The air in the dungeon's natural chamber was still, filled with humidity that made Eren's hair stick to his forehead.
Nyssa curled up in a corner, still naked under the now-useless dirty cloth, hugging her gelatinous knees to her chest. She looked at him with huge, shining eyes—but there was something in them beyond the usual devotion.
Eren pulled up the system display.
[Affinity: 91%]
He frowned.
Far below expected.
He pulled mental data like someone checking server logs.
Maximum speed. Maximum force. Inferior result.
He wiped his sweaty face.
What happened?
He lifted his gaze to Nyssa.
She looked away, biting her trembling lower lip, the color darkening to a deeper blue.
"M-master..." she murmured quietly. "I... I... I want… in another way."
He tilted his head slightly.
"Explain."
She sniffled.
"I want... to please you... properly."
A tense silence stretched. The wet sound of her breathing filled the chamber.
"How?"
Nyssa bit her lip again. The color deepened.
"Let me... use my mouth."
Eren didn't move. He just processed.
Oral sex. Bodily fluid. Mutual consent. Valid ritual.Possible greater connection through individual focus. Better emotional immersion.
He didn't reply with words. He just sat cross-legged on the cold floor.
"Alright."
Nyssa trembled as she let out a sigh. Then she crawled forward slowly, her translucent body glowing in the dungeon's dim light. The improvised dress fell to the side, revealing every liquid, shifting curve molded to please him.
When she got close, she looked him in the eyes.
"I'll be... gentler this time."
Eren didn't react. He just studied her every move.
She leaned forward—and her whole body seemed to flow. Her head elongated, like her neck turned into a soft stem. Her translucent hair moved like living water, spilling to one side.
Her mouth curved in a small, embarrassed smile.
"Relax, master... I'll take care of you..."
He analyzed in silence.
Controlled transformation. High malleability. Possible multiplicity of contact points.
Nyssa moved even closer. Her wet, cold hands slowly climbed up his thighs, pressing and molding around every muscle.
Eren held his breath.
Low temperature. Unusual friction. Adaptable.
When her mouth finally enveloped him, it wasn't just contact. It was a full embrace—the lips molding perfectly, the tongue splitting into thin strips that caressed in ways almost impossible to describe.
He let out a low growl, the first break in his expression in a long time.
Nyssa moaned against him, the sound vibrating through her translucent body.
"Mmm... I like... you so much... master..."
Her hands never stopped. Each finger duplicated, stretched, caressing more, more, wrapping around him completely. Eren's legs tensed.
Affinity...
He didn't need to call the display. He felt it.
Rapid increase. More stable.
She alternated the rhythm. Sometimes slow, deep, her mouth molding carefully and reverently to his shape. Sometimes fast, urgent, letting out wet, embarrassing sounds.
"Aah... nnh... master..." she murmured between pauses, looking up at him with eyes shining with genuine pleasure. "I want... you to like it... I want to make you happy..."
Eren exhaled in sharp bursts.
Heightened emotion. Sincerity detected. Contract reacting.
She changed form again. Her head split in two—two mouths, two tongues, each working independently. He gasped.
Multiple stimulation. Maximum intensity.
Nyssa moaned louder.
"M-master... it's so good... so good..."
Her tongue thinned into fine tentacles, caressing each sensitive spot with almost mathematical precision. Her mouth opened and closed with wet pops.
Eren couldn't maintain total composure anymore. His hand sank into her gelatinous hair, pulling. She moaned in response, accelerating even more, vibrating around him as if she were part of his own body.
He felt the climax rise brutally.
[Affinity... 110%...]
[113%...]
[118%...]
The mental display almost flickered.
When he finally exploded, it was as if something primal inside him had been torn loose. He let out a low growl, hips arching forward, abdominal muscles contracting.
Nyssa didn't stop. Her mouth swallowed everything, molding so nothing escaped, moaning at the taste, eyes closed in pure bliss.
[120%.]
He relaxed like an exhausted animal, his chest rising and falling in tremors.
Nyssa released him slowly, reorganizing into a single body, licking her lips with the split tongue that soon returned to normal. She smiled, blushing.
"Did I... do it, master?"
Eren opened his eyes with effort.
Contract strengthened. Full properties.
He gave a single nod.
"Yes."
She let out a relieved sigh, leaning against him, still naked, still malleable.
"Then... let's... beat the boss... together?"
He inhaled deeply.
Ready.
"Yes."
He stood up, feeling his muscles less rigid—more elastic, more alive. Nyssa molded herself at his side, smiling with a mix of mischievous glint and sincere affection.
Eren turned toward the boss's stone door, his eyes gleaming with cold calculation.
[Affinity : 120%]
120% affinity. Variables stabilized. Properties confirmed.
He adjusted the pack on his shoulder.
"Let's go."
Nyssa clung to his arm like a living shadow, ready for the fight.
