"Show your tentacles."
The surprise was palpable, radiating from Kree’s form in a silent, tangible wave.
Athiel watched the creature’s pupil-less dark eyes widen, the glowing cracks along its massive chest pulsing faster, brighter, like sothing inside it had been startled awake.
For a mont, it hesitated.
Just a mont.
But Kree listened, though.
It always did.
It knew what happened if it didn’t.
Slowly, the tentacles ca out from its back, one after another, unfurling with a quiet, organic movent that almost felt too alive to watch this closely.
They shifted slightly in the air, uncertain.
Waiting.
Athiel was amazed.
His breath caught, his chest tightening as his heart started beating faster, harder, each pulse loud in his ears.
’I don’t want to wait anymore.’
The thought ca sharper this ti, heavier.
He reached out without thinking further, grabbing one of the tentacles and pulling it toward him.
The one he had grabbed lay slack and unresisting in his palm, a cool, smooth weight of living muscle that twitched faintly at his touch.
It didn’t fight him.
Didn’t pull away.
It simply... let him.
’It probably doesn’t understand,’ Athiel thought, a strange thrill curling through him, sothing that felt both new and familiar in a way he didn’t want to question. ’It’s following orders, but doesn’t know what I’m about to do.’
That realization only made his grip tighten slightly.
The texture was fascinating—firm yet yielding, with a subtle ridge pattern that felt almost engineered.
He guided it, slowly, deliberately, toward his own bare chest.
His formal shirt was gone, crumpled on the floor beside his ruined coat, leaving his pale, lean torso exposed.
The air of the lab felt cool against his skin, a stark contrast to the heat building inside him.
The tentacle’s tip, blunt and rounded, touched the center of his left nipple. A jolt, sharp and electric, shot through him.
Ah.
It wasn’t pain.
It was a sensation so precise, but not so foreign, it bypassed his usual analytical filters and went straight to his spine.
His nipple hardened instantly, pebbling under the alien touch. Kree made a sound—a low, guttural rumble from deep within its chest. Not a word, but a vibration of pure confusion.
"Move it," Athiel commanded, his voice husky but firm.
He wasn’t asking. He was demonstrating. He used his own hand to show the motion, a slow, circular rotation right against his sensitive flesh. "Like this."
Like how it did before.
"M-Master?" Kree’s imnse body shifted.
The tentacle in Athiel’s hand began to move, mimicking the motion with an eerie, perfect accuracy.
The circular pressure started, a gentle, relentless orbit that made Athiel’s breath catch. Pleasure, raw and unadulterated, blood from that single point.
"Oh...ah..."
It spread through his chest, warming his ribs, making his heart beat a frantic rhythm against his sternum.
He couldn’t stop a low moan from escaping his lips. His head tilted back, his dark hair falling against his neck.
The sensation was imnse.
It was more than physical; it was a validation.
Every hypothesis, every clandestine observation, every forbidden curiosity he had buried for years was coalescing into this mont. Kree was not just a specin.
It was a key. And Athiel was turning it.
His legs trembled.
He locked his knees, forcing himself to stand steady even as his body threatened to buckle.
"Don’t," he breathed out, his eyes snapping open to fix on Kree’s face. "Do not move on your own. If you do, I will punish you. Do you understand?"
Kree stared.
The rumbling ceased.
The creature’s expression was impossible to read, but the intensity of its focus was absolute.
It nodded, a slow, deliberate dip of its head. ’Did it just nod its head?’ Athiel asked himself, but his mind couldn’t fully process anything anymore.
Because as Athiel’s threat left his lips, sothing else appeared.
Between Kree’s thick, muscular thighs, the massive erection he’d seen before erged again, rising with a slow, inevitable urgency.
It was monstrous, thick and long, with the sa glowing, cracked pattern as the rest of its skin, pulsing with a deep, inner light.
It was a blatant, physiological response.
’So now it knows what’s happening.’ Athiel realized, his scientist’s mind racing alongside his arousal.
The knowledge sent a fresh wave of heat through him. He reached out, his hand trembling slightly now, and grabbed another tentacle.
"I need more."
This one was slightly thinner, more supple. He guided it to his right nipple, mirroring the first.
As the cool, ridged tip touched his other nipple, he gasped aloud.
The dual stimulation was overwhelming.
"Ah...ahh..." The circular motions synchronized, creating a rhythm that echoed through his entire being. His moans beca continuous, soft, helpless sounds that filled the quiet lab.
He was losing control.
The analytical part of his mind was drowning in a sea of physical feedback.
Every rotation sent sparks of pleasure shooting down to his groin.
He could feel his own cock, hard and neglected, pressing against the remains of his trousers. The fabric was a frustrating barrier.
’Later,’ he thought, his focus narrowing to the two points of contact on his chest. ’This is the primary experint.’
As if this were still an experint.
Kree watched, utterly still except for the working tentacles and the slow, rhythmic pulse of its own enormous sex.
Its forked tongue flicked out once, a quick, testing motion.
Kree’s hands held Athiel’s waist, a loose but possessive cage.
Athiel lets it.
It was only touching.
And for so reason, that also sent waves of excitent inside of him.
The tail swayed gently, a trono to the building tension.
Athiel’s back arched. The pleasure was cresting, a wave about to break. He was panting now, each breath a shallow, needy intake.
"Faster," he whispered, the command slipping out before he could consider it.
The tentacles obeyed. The circular motions accelerated, the pressure increasing just enough to make the pleasure sharpen, edge into a sweet, aching intensity.
"Agh...ah! Oh my...fucking..." Athiel cried out, a short, sharp sound of pure surrender.
His hands, which had been guiding the tentacles, now fell away, gripping instead at Kree’s solid forearms for support.
His nails dug into the glowing, cracked skin.
He was a scientist observing his own degradation, and it was the most exhilarating thing he’d ever felt.
The humiliation he’d feared was gone, burned away by a curiosity so profound it consud everything else.
’This is its biology,’ he thought, his mind clinging to the last shred of rationality. ’This is natural.’
Athiel’s body was singing, a taut wire of pleasure vibrating just beneath his skin.
The twin tentacles worked his nipples with a relentless, perfect rhythm, sending shocks of sensation straight to his core.
His cock strained against the fabric of his trousers, aching, dripping.
’I’m so close.’ But the thought was a pinprick of resistance in the overwhelming haze. ’Not yet. Not like this.’
This wasn’t the goal. The goal was understanding. The goal was to see what Kree could do.
With a gasp that tore from his throat, Athiel shoved the tentacles away from his chest.
The sudden absence of sensation was a cold slap, leaving his nipples throbbing and oversensitive.
Kree whimpered, a high, pained sound, but the tentacles retracted instantly, coiling back against its body as if wounded.
’It listens. It always listens.’ The power of that knowledge surged through him, hotter than the arousal.
He loved that it always listened.
God.
The amount of power he had to have a monster so big listen to him.
He pushed Kree’s hands from his waist next, the creature’s massive grip yielding without protest. Athiel stepped back, his legs shaky but determined.
The lab’s cool air hit his sweat-damp skin, a sobering contrast to the heat Kree radiated.
It made him shiver.
His fingers worked at the buttons of his trousers, clumsy with urgency.
The fabric parted, and he let them fall, pooling around his ankles.
’I want more. I want more. I want more.’
His own erection stood fully exposed, pale and flushed, a stark contrast against his lean fra. He ignored it for a mont, his gaze fixed on Kree.
’I want...’
The creature was staring, its pupil-less eyes wide and dark. Its forked tongue flicked out again, tasting the air between them.
’...sothing inside.
The massive, glowing erection between its thighs pulsed visibly, a thick vein of light throbbing along its length.
A bead of clear fluid gathered at the tip. Kree was practically salivating, a low, hungry rumble building in its chest.
Athiel turned around, presenting his back to the creature. The act felt deliberate, a calculated risk.
’I want all of that inside.’
He reached behind himself, his hand finding one of the thicker, main tentacles that still hovered near Kree’s side.
It was warm, firm, the ridges of its texture pressing into his palm. He pulled it forward, guiding it toward himself.
"Just one for now," Athiel commanded, his voice rough but clear. He angled his body, presenting the cleft between his cheeks. "Put it inside."
