Klem's visor emitted a low, prolonged hum, almost like a distorted electronic purr. It was not an error sound or a warning — it was the cybernetic equivalent of a ragged gasp. Her hands — one still closed around Leo's left thigh, the other open and trembling against his lower abdomen — paused for an instant, as if the system were recalculating priorities in real time.
Leo felt his own pulse hammering in his throat. Water from the shower still dripped from his hair and fell in cold drops onto her shoulders, splattering the matte black plates covering her collarbone. Each drop seemed to evaporate on contact with the silver circuit lines, which now glowed with nearly blinding intensity along her inner thighs and abdomen.
"I don't... know how to proceed," said Klem. The modulated voice cracked on the last syllables, losing part of its metallic filter. For the first time she sounded vulnerable, almost human. "The biological interaction manuals are locked at level 5. I only have diagrams. Diagrams don't breathe. They don't... beat."
Leo looked down at her. Kneeling before him, visor tilted upward as if trying to capture every millimeter of his expression, she looked at once lethal and lost. The quantum impulse boots kept her slightly elevated on her heels, which accentuated the curve of her glutes and the tension of the synthetic muscles in her calves. Her silver-white hair clung to the pale skin of her neck from the ambient humidity of the cell.
"Then don't follow the manuals," he told her quietly. "Do what you feel."
Klem tilted her head. The movement was so precise it seemed calculated to the millimeter, but the faint tremor in her fingers betrayed her.
"Feeling is not in the protocol. Feeling is... contamination."
"And yet here you are." Leo reached out slowly and brushed his fingertips along the lower edge of the visor, right where the organic skin ended and the sealed polymer began. "Touching me. Breathing in my scent. Measuring my temperature. That's already contamination, Klem. And it doesn't look like you want to stop."
She didn't answer with words. Instead, her left hand slid up along the inside of his thigh until it grazed the base of his erection. The contact was firm, clinical at first, as if she were assessing a piece of equipment. But then her fingers closed with more pressure, exploring the texture, the girth, the pulsing heat. A circuit on her forearm flared brighter and Leo felt a faint electric tingle — not painful, but stimulating.
"Pulse 138," she murmured. "Maximum vasodilation. Dopamine and testosterone release detected." She paused. "My own system... registers similar anomalies. Core temperature increase of 1.4 degrees. Blood flow redirected to pelvic regions. Organic lubrication increased by 320% above baseline values."
Leo let out a rough laugh.
"You're giving me a medical report while you touch me?"
"I am... documenting," she replied, almost defensively. "To understand why my emotional containment core is failing in cascade."
Her fingers moved with more confidence now, sliding up and down in a slow but relentless rhythm. It wasn't skilled, it wasn't gentle — it was instinctive, raw, as if she were testing the limits of her own capacity for control. Each stroke made the circuits along her inner thighs ignite in undulating patterns, like veins of liquid light beneath the skin.
Leo pressed his other hand against the wall to steady himself. The contrast between the coldness of the steel and the heat radiating from her body was overwhelming.
"Take off the visor," he said suddenly.
Klem froze. The hand holding him stopped mid-motion.
"Prohibited," she said automatically. "The visor is the primary interface. Facial exposure equals level-1 vulnerability. It is only permitted during maintenance among unit sisters."
"There are no sisters here," he replied. "Just me. And you. And this cell that stopped being provisional for either of us a long time ago."
The visor emitted a sharp tone, like a distant alarm. Then silence.
With an almost painful slowness, Klem raised both hands to the sides of her head. She pressed two invisible points behind her ears and there was a hiss of decompression. The visor split into two halves that slid back and folded against the nape of her neck like the wings of a mechanical insect.
For the first time, Leo saw her face.
Large eyes, a near-metallic silver-gray, with vertical pupils that dilated and contracted like a cat's in the dim light. Short white lashes. A fine, straight nose. Full lips, pale, slightly parted in an expression of perpetual surprise. The skin around her eyes and cheeks carried a faint iridescent sheen, as if dusted with nanoscale particles. No scars, no imperfections — a laboratory-cultivated beauty, refined to the point of being unsettling.
Klem blinked. Once. Twice. As if recalibrating reality without the visor's filter.
"My direct optical sensors... are inferior in resolution," she murmured. "But superior in... proximity."
Leo stared at her.
"You're beautiful," he said without thinking.
The word seemed to strike her like a physical blow. Her pupils dilated until they nearly erased the silver iris.
"Beautiful is not a military evaluation parameter," she whispered.
"Then evaluate me," he answered. "And tell me what you see."
Klem rose to her feet in a fluid motion, almost supersonic in its precision. Now they were face to face, centimeters apart. She was slightly shorter, but the impulse boots brought her nearly level with him. She extended one hand and traced with her index fingertip along the line of Leo's jaw, then down his neck, his chest, his abdomen — stopping just above his erection.
"I see... vulnerability," she said. "And strength. And heat. So much heat." Her eyes dropped. "I want to... consume it."
Without warning, she leaned forward and pressed her lips against his.
It was not a gentle kiss. It was pure hunger. Teeth clashing, an invasive tongue, a metallic moan that vibrated in both their throats. Leo responded on instinct, wrapping his arms around her and pulling her against his bare body. He felt the cold armor plates against his warm skin, the glowing circuits now pulsing like a second heartbeat.
Klem pushed him backward until his back hit the shower wall. The impact was controlled — she knew exactly how much force to apply without breaking anything. Her hands dropped to Leo's glutes and lifted him slightly off the floor — easily, with her graphene nanomuscles — aligning their hips.
"I don't know... how to do this correctly," she panted against his mouth.
"There is no correctly," he answered, biting her lower lip. "Just do it."
She released him just enough to unclasp the magnetic fastening of the reinforced corset. The plates snapped open and fell to the floor. Beneath was only pale skin, firm breasts with already-hardened pink nipples, and a flat abdomen crossed by circuit lines that converged toward the navel like rivers of light.
Klem tore off her greaves in a supersonic motion. The boots landed on the floor with a metallic clang. Now she was nearly bare, wearing only the spine and forearm plates. Between her thighs, the minimal silver-white pubic hair glistened with moisture. The sweet-metallic scent intensified, mingled with something organic, musky, unmistakably aroused.
Leo lifted her by the waist — she allowed it, surprisingly yielding — and turned her so her back was against the wall. Klem's legs coiled around his hips with inhuman strength, but without hurting him. Her heels dug into his glutes.
"Now," she whispered, silver eyes blazing. "I want to feel it inside."
Leo needed no further invitation.
He entered her in a single slow but firm motion. Klem arched her back against the wall and let out a cry that was half human moan, half electronic static. Her inner walls were hot, tight, with a subtly ridged texture that seemed to adapt to him in real time — nanotechnology, perhaps, or simply enhanced biology. Each thrust made the circuits across her body ignite in chaotic patterns, lighting the cell with flashes of silver and red.
She didn't know how to modulate pleasure. Her hips moved at supersonic speed in short bursts, then stopped trembling, as if the system were overloading. Leo held her tighter, setting the rhythm — deep and steady.
"More..." Klem panted. "More data... more sensation... more..."
Her nails — retractable but blunted now — dug into his back, leaving red furrows. It didn't hurt; it was just another layer of intensity.
Leo felt the climax approaching too quickly. He tried to slow down, but Klem locked him in with her thighs and kissed him again, devouring him.
"Don't stop," she ordered. "Containment protocol... broken. Everything broken."
He obeyed.
When he reached the edge, he drove in deep and came inside her with a guttural groan. Klem convulsed instantly — an orgasm that made every circuit in her body blaze all at once, like a supernova contained within skin. Her cry was an electronic wail that reverberated off the steel walls, and for one second Leo could have sworn he felt a pleasurable electric charge run the length of his spine.
They stayed like that, locked together, breathless. Leo's sweat mingled with hers — organic and synthetic at once. Klem's circuits began to dim slowly, settling back into a faint glow.
"Complete contamination," she whispered against his neck. "No purge is possible."
Leo smiled, exhausted.
"Welcome to the real world, Klem."
She lifted her head. Her silver eyes looked at him with something new — not curiosity, not hunger. Something softer. More dangerous.
"I want more," she said simply. "I want everything."
At that moment, the surveillance camera — which she had deactivated earlier — blinked once in red.
Someone, somewhere in the base, had just noticed the anomaly.
