CHAPTER 18: TRIPLE INTIMACY

The light flickered on the stone walls, casting thick shadows, as if the flames were curious fingers exploring every corner. The air was heavy with heat and something undefinable—a scent of nervousness, raw expectation, of desire so dense it felt like it could be cut with a knife.

Kaela stretched out on the mattress, her hips arched as if offering her body to her own lust. Her warm skin glistened with moisture, her rapid breathing causing her breasts to rise and fall in a rhythm that was pure promise. She wasn’t afraid of being watched—the slitted amber eyes sparkled in the flickering lamplight, predatory, amused, hungry.

"Kaela wants. Kaela commands. Kaela does," she thought, savoring the power in the atmosphere.

Beside her, Nyssa trembled.

The translucent body wavered in an almost human form, the dense slime reorganizing to display soft feminine contours, yet full enough to invite caresses. She held the crumpled cloak against her chest, her partially formed face—cheeks flushed with color as if blushing beyond the limits of logic.

"I can’t... I don’t know..."

Her thought was a muffled lament, the moist sound of her body delivering little plops and crackles as she moved, uncomfortable.

Kaela turned her face to her, eyes half-closed, lips curling into a smile that was half invitation, half command.

"Softie... don’t think too much. Feel."

The voice came out deep, drawn out, the words with that unmistakable yet wrong way of Kaela: intimidating, yet seductive.

Nyssa moaned softly, the sound vibrating moistly, her hands trembling as the cloak slipped.

Eren watched everything.

From the corner, sitting in a crooked chair, he saw how the two of them breathed. How the tension made Kaela stand even taller, her chest thrust out in a challenge, while Nyssa shrank, the shapes dissolving at the edges as if she didn’t know what she wanted to be.

He analyzed carefully.

Affinity... still hasn’t changed.

The System, as cruel as ever, gave him nothing. No notifications. No progress.

But he kept watching.

He was learning.

Kaela wasn’t afraid to show anything. She wanted Eren to see. She wanted Nyssa to melt for her, in every way.

Nyssa... she wanted not to want. But her body pulsed, expanded, trembled, reacted to every stimulus as if begging for more.

Kaela reached out, running her fingers over Nyssa’s liquid thighs.

"Cold. Delicious."

Nyssa let out a wet moan, half sob.

"I... I don’t know..."

Kaela growled, her fingers lightly squeezing.

"Yes, you do. Your body knows."

Nyssa closed her eyes, trying to deny it, but the form wavered, firming even more feminine, breasts forming under the touch, hips opening, instinctively seeking the warmth of her partner.

Kaela laughed.

"That’s how I like it. Pretty. Wanting."

Nyssa moaned louder, blushing, her whole body trembling.

Eren felt his pulse quicken.

He didn’t move, not yet. But his eyes burned. Every detail absorbed—the curve of Kaela’s hip, the marks of old teeth on her skin, the wet shine on her slightly open mouth. Nyssa trying to hide her face but exposing herself in an even more erotic way, as if shame was an essential part of the pleasure.

Kaela leaned in, licked the translucent neck.

"Your taste. Sweet."

Nyssa trembled.

"S-stop..."

But she didn’t push away.

Kaela smiled, her voice low, wrong, drawn out:

"No. You want it. I know."

Nyssa sobbed.

"I... I don’t know..."

Kaela kissed with force, sucking, marking with her mouth. Nyssa muffled a scream, a wet, shameful sound so embarrassing that Eren felt himself throb even as he tried to maintain control.

Kaela released the kiss with a pop.

"Speak. Say it."

Nyssa shook her head.

Kaela bit her lip gently, teeth grazing, without breaking anything—just to impose.

"Say it."

Nyssa whimpered.

"I... want."

Kaela smiled, victorious.

"Good."

She turned her face to Eren, amber eyes shining.

"Come. Your turn."

Eren stood up.

His eyes cold, calculating, but his chest heaved.

He approached, crouched near them.

Kaela held Nyssa in her lap, almost possessive, her large hands squeezing the soft, slippery hips that molded to her touch.

Nyssa tried to hide her face in her partner’s shoulder, trembling.

"T-too... t-too embarrassed..."

Kaela licked her face, dirty, raw.

"Good. Stay embarrassed. Stay hot."

Eren took a deep breath, running a hand through his disheveled hair.

"Relax. Let’s take it slow."

Kaela laughed.

"Kaela doesn’t like slow."

Eren looked at her, cold.

"But Nyssa needs it."

Kaela growled but didn’t reply.

Nyssa sobbed.

"P-please... slower..."

Kaela sighed, her lips touching her friend’s ear.

"Okay. I’ll go slow. For you."

Eren analyzed every sound, every tremor.

His hands went to Nyssa’s hips, firm but gentle.

"Like this?"

She moaned, nodded, hands clinging to Kaela as if she were about to sink.

Kaela whispered dirty words in her ear, wrong, spoken amidst moans:

"Delicious. Warm slime. You make beautiful noise."

Nyssa sobbed between moans, getting wetter—literally and figuratively—surrendering, molding.

Eren remained present.

His touch measured, firm, but unhurried.

Kaela writhed, rubbing her thighs, masturbating as Nyssa unraveled against her.

"Go, Softie. Cum for Kaela."

Nyssa screamed, a sound grotesquely wet, vibrating, trembling.

Kaela moaned along, her hips moving, breath tearing through her throat.

Eren still moved against Nyssa, but now more slowly.

His hands held the soft hips firmly, feeling the tremor that passed through her entire body.

Each thrust generated a wet, smacking sound that echoed indecently through the broken columns.

Nyssa sobbed and trembled as if having spasms. Well, she actually was having spasms.

"I-it’s too much... I... please..."

Kaela laughed softly, her voice hoarse and drawn out.

Nyssa couldn’t take it anymore. Her body dissolved into convulsive tremors, the viscous texture throbbing as if there were a heart pulsing with liquid pleasure.

Her cry echoed moistly, choked, a mix of sob and moan so laden with shame that it drew a hoarse moan even from Kaela.

Eren felt the grip, her gelatinous body trying to absorb his every movement, but he didn’t allow himself to lose control. He stayed there, inside her, for a moment longer, breathing heavily, eyes fixed on Nyssa’s contorted face.

[Affinity... 100%.]

He saw the notification flash in the corner of his vision, a gentle glow. But there was no time to savor the achievement. He needed Kaela now.

Kaela, as if already knowing what was to come, growled low, almost feline, licking the sweat from her lips. With an agile motion, she positioned herself at Nyssa’s belly level, getting on all fours over her.

Her strong legs spread in a wide V, hips raised with unabashed naturalness, leaving Nyssa partially shielded beneath her like a treasure already claimed.

"Now it’s Kaela," she said, her voice low, guttural, amber eyes burning in Eren’s direction.

Nyssa still moaned, weak, eyes teary. She tried to compose herself, but Kaela gave her no respite. The half-wolf leaned over the slime’s belly, kissing and licking her with slow, almost reverent movements. Her mouth opened wider, sucking hard where the liquid skin quivered, drawing renewed moans from Nyssa.

"It’s... so... much..."

Kaela laughed, licking again.

Eren watched it all, cold eyes analyzing, chest rising and falling in a controlled manner, even as his member throbbed.

This will probably conclude the contract.

He took a deep breath, stepped forward, the sound of his boots on the stone echoing definitively.

Kaela looked over her shoulder at him, disheveled hair falling over half-closed eyes.

"Come. Kaela wants now."

She swayed her hips at him, shamelessly displaying herself.

"Do it. Hard."

Nyssa whimpered softly, curled up under Kaela, yet arched slightly to accept the kisses, the moist tongue dragging within her flaccid flesh.

Kaela growled words, twisted and wrong. Nyssa moaned, embarrassed, her mouth trembling.

Kaela swayed more.

Eren approached, cold and methodical. His hands gripped Kaela’s hips with brute force, feeling the firm flesh quiver beneath his fingers. He positioned himself behind her, the tip brushing, forcing entry with controlled movements, slow at first.

Kaela gasped, throwing her head back, chest pushing forward to crush Nyssa further beneath her.

"Ahh... more... Kaela wants more!"

He didn’t respond. He just obliged.

The first thrust was slow and deep.

The second, faster.

The rhythm grew in an almost cruel crescendo, hips slamming with a dull thud against Kaela’s firm thighs.

She screamed, growled, words jumbling as her mouth was completely occupied with something else.

Nyssa whimpered, squeezed between the ground and Kaela’s long tongue, but did not resist. Translucent hands trembled, trying to grasp something.

Kaela gripped Nyssa’s hips with brutal tenderness.

Nyssa sobbed in response, wet moans vibrating in echo.

Eren remained firm, eyes fixed, controlled. But his body burned, the heat almost unbearable. Each thrust was measured, cruel, delicious.

Affinity...

He saw the notification appear in the corner of his vision.

[Affinity with Kaela: 99%...]

He accelerated.

Kaela was now roaring, a primal scream echoing among the cracked columns, the wind carrying the obscenity to the skies.

Nyssa trembled beneath her, dissolving into wet sounds of pure surrender.

[Affinity with Kaela: 100%]

The system glowed more brightly.

[Getting there...]

Eren felt his whole body seize, pleasure rising like a murderous fire.

Kaela rolled her eyes, howling his name wrongly, erratically.

Nyssa cried softly, almost suffocated.

And then everything collapsed.

Moans.

Sobs.

The system released one last cold, almost triumphant message:

[Triple fusion successful.]

Eren panted, forehead resting against Kaela’s sweaty back, fingers digging into firm flesh.

The sound of moans gradually faded, replaced by a dense, humid silence, broken only by the irregular sound of breathing.

Kaela trembled under Eren’s hands, firm muscles tensing in involuntary spasms that made her release deeper, more intimate growls.

Her head was bowed, disheveled black hair falling over Nyssa, who in turn dissolved into liquid contractions, emitting muffled plops that mingled with wet moans.

Eren kept his eyes half-closed, breathing heavily. The heat still coursed in waves over his skin, an electric residue of pleasure, but his mind remained cold, calculating, focused on analyzing everything.

He felt a tingling creeping up his arms, as if something slithered beneath his skin. His vision wavered for a moment, and the System flickered in his mental interface, glowing brighter than ever.

[System]

[Triple fusion successful.]

[Affinity: 100%. Attributes shared.]

[New contract: ABSOLUTE BOND ESTABLISHED.]

The text slowly disappeared, replaced by a new window unfolding with digital fluidity.

[Details:]

[Eren Vale: +50% Lupine Strength (Kaela), +50% Elastic Resilience (Nyssa)]

[Kaela: +50% Emotional Control (Eren), +50% Elastic Resilience (Nyssa)]

[Nyssa: +50% Lupine Strength (Kaela), +50% Emotional Control (Eren)]

[Linked status. Enhanced combat synergy.]

Eren remained motionless for long seconds, watching the System windows disappear one by one until only darkness remained, punctuated by the faint light filtering through the ruins’ cracks.

He exhaled slowly. He felt different.

He felt it. Muscles more tense, as if pulsing with the need for explosion, blood running thick in his veins. Arms covered with thicker fur, black nails curved like restrained claws. His jaw ached, too tight. His lupine side didn’t want to talk — it wanted action. Violence. It was pure instinct, barely contained.

His arms, once just strong and defined, were now covered in thicker, darker fur extending to the forearms — not grotesque, but visibly more animalistic. The nails were slightly elongated and black, resembling claws. Every muscle seemed to pulse with something primal, a brute strength that wasn’t solely his.

Impulse.

The urge to resolve things immediately, to attack any threat without hesitation. An animal urgency. It wasn’t his, but now it was.

He furrowed his brow.

"Kaela."

Part of the strength came from her — but along with it, the instinct. He didn’t just gain power; he also gained the flaw. The desire to snarl, to kill without thinking.

He turned his face, analyzing.

Kaela was panting, still on all fours, but more relaxed than ever. Her body hadn’t lost its lupine strength — the muscles were still tense, defined — but there was now a softness to her movements. Her lupine ears trembled less, more relaxed, and her tail, once tense, wagged in a slow, almost lazy rhythm.

She turned her face to Eren, her amber eyes half-closed.

"I feel more, sluggish."

The voice came out articulated. It was still guttural, but the sentences were complete.

Eren could only analyze.

Kaela probably gained my emotional control. Half. But not completely. She’ll hold back more. Speak better. But she’ll still bite.

Nyssa was still sobbing softly, trying to recover. But her body was different. Once so fluid, amorphous, now it had firmer, taller lines — almost truly human. Her translucent thighs were more defined, her chest rose and fell with breasts formed of denser slime.

She shook her head, her translucent face taking on clearer features.

"I feel... harder..."

She raised an arm and looked at it, impressed by her own form.

Kaela laughed softly, a sound almost affectionate.

"Haha, the squishy one is firmer now."

Nyssa blushed, but didn’t dissolve.

"Shut up...!"

Then she put her hand over her mouth. Eren and Kaela were surprised. Where did that courage come from? Well, Eren already knew the answer briefly.

She gained lupine strength. She’ll stop trembling so much. But she’ll also want to fight. She’ll get more irritated, I imagine.

Eren watched everything in silence, analyzing. His mind was a bit hazy — not from the usual exhaustion, but from something new. A stupor. A strange softness that didn’t match him.

He closed his eyes for a moment, frustrated.

Wrong contract.

He cursed himself silently.

I didn’t control it enough. I managed to distribute abilities — but also the flaws.

His fist clenched slowly.

It was a mentalization error. Hard to think of a perfect contract while fucking.

He opened his eyes, took a deep breath.

Next time, focus. Clear definition. Selective distribution. No blind transfer.

The System hadn’t warned anything about this — because he hadn’t visualized the clauses correctly.

Absolute Contract is no easy trick. It’s mental architecture. I need to learn to build.

He relaxed his hand, spreading his fingers. He looked at the two who seemed too tired to be as animated as he was. With that, they slept with eyes almost closed.

Kaela growled softly even in her sleep. Nyssa emitted gentle plops, melting in an almost cute way on the floor.

He noticed their scent was stronger, more addictive. His heart beat slowly, heavily, as if it wanted to rest — something unusual for someone who didn’t need to sleep.

He looked at his right arm.

There, engraved on the now paler skin covered with dark fur, was a tattoo.

Black lines and curves drew ancient runes, connecting in a pattern both tribal and runic at the same time. It seemed alive — pulsating slightly with the same amber hue of Kaela’s eyes, mixed with

Nyssa’s watery green.

[Absolute Contract: Triple Union.]

He stretched his arm, turning the wrist to examine it.

A seal.

The System flickered one last time, with an almost solemn tone:

[Status Updated.]

[Triple Fusion Confirmed.]

[Affinity 100%. Contract Registered.]

[Attributes Shared.]

Eren exhaled slowly, his heavy arm resting between them.

"Great."

He didn’t smile.

But he didn’t pull his arm away.

Kaela snuggled into Nyssa, and Nyssa into Kaela. It seemed like the two had known each other for a long time and were already very close.

Finally, Eren achieved what he had long desired: Unite the two, change them, so they would be ready for what was to come.

However, they still needed training.

"That’s enough — Eren clapped his hands, waking them both. — Let’s continue on the road."

"Eeeeh...?"

"Aaaaargh!!!"
