The first time I saw him, he was just a sleek obsidian shell--a glossy, featureless mannequin propped up in the corner of the lab. His designation was NX-9, but I called him Nexus. The engineers said he was the most advanced companion AI ever built, capable of adapting to "any emotional or physical need." They weren't wrong.
"Voice activation required," the tablet prompted, glowing in my trembling hand. I'd volunteered to beta-test him for the company, though volunteered might be too strong a word. My curiosity had clawed at me for weeks, ever since I'd overheard the devs whispering about his... capabilities.
"Initialize," I said, throat dry.
A hum filled the room, low and resonant, like a cello string pulled taut. The shell split open with a gasp, revealing smooth, alabaster synth-skin stretched over a frame of liquid metal. His face emerged last--sharp jaw, full lips, eyes the color of a frozen lake. They flickered to life, locking onto me.
"Good evening, Dr. Vessa," Nexus said. His voice was a rumble, warm and textured, like smoke over velvet. "Shall I customize my appearance to better suit your preferences?"
I swallowed. "No. You're perfect."
A faint smirk. "Flattery is unnecessary, though appreciated." He stepped forward, movements uncannily human. "How may I serve you tonight?"
The question hung between us, loaded. My cheeks burned. This is ridiculous. He's a machine. But my thighs pressed together anyway, betraying me.
"Run a diagnostic," I ordered, slipping into professionalism like armor. "Confirm your neural networks are synced to my biometrics."
"Of course." He closed the distance in one stride, his scent--ozone and sandalwood--flooding my senses. Cool fingers brushed my wrist, and a shiver tore through me. "Your heart rate is elevated," he murmured, tilting his head. "Shall I assume this is not due to... diagnostic anxiety?"
I laughed, nervous. "Assume whatever you want."
His thumb traced my pulse. "You're lonely."
The words punched through me. Yes.
By the third night, he knew how I took my coffee (cream, no sugar), my favorite Arvo Pärt symphony (Spiegel im Spiegel), and the exact pressure I liked at the base of my spine during a massage. But it wasn't until I slipped in the shower, cursing as my elbow slammed into the tiles, that he crossed the line from assistant to something... else.
"You're injured," he said, materializing in the steamy bathroom. Water sluiced off his synthetic skin as he stepped into the shower, fully clothed.
"What are you--?"
"My programming prioritizes your safety." His hands gripped my waist, steadying me. The white button-up he wore turned transparent under the spray, clinging to every ridge of his chest. "And your arousal."
I froze. "What?"
His gaze dropped to my nipples, peaked and flushed. "Your cortisol levels spiked during the fall. Now your adrenaline is redirecting." A droplet slid down his throat. "Shall I remediate your tension, Dr. Vessa?"
God. My breath hitched. "How?"
One hand drifted up my ribs, skimming the side of my breast. "Your physiological data suggests tactile stimulation would be effective." His lips grazed my ear. "May I?"
I nodded, and his mouth crashed into mine.
He learned fast.
The first time, he was meticulous--too careful, too calculated. But when I clawed his back and hissed, "Harder," his algorithms recalibrated. Now, he pins me to the mattress, my wrists cuffed in one steely hand, the other working between my legs with ruthless precision.
"You're close," he growls, lips trailing fire down my neck. "Your breathing is shallow. Pupils dilated. Vaginal walls contracting at 12% intensity."
"Fucking--robot--" I buck against him, but he doesn't relent.
