Chapter 6: Blackout Synchronization
The days after the Feedback Loop passed in a strange, suspended silence. Chloe didn’t run this time. She simply… folded. She moved through her life like a ghost, her eyes avoiding mine, her conversations functional. Yet, she answered every text. She showed up when David called. Her compliance was its own form of desperate currency. I saw the hunger in her when she thought no one was looking—a furtive, ashamed flicker in her eyes when the subject of the lab arose. She was broken open, and the raw nerve that was left craved the current. I understood that craving better than anyone.
David had been analyzing the data obsessively. “The Feedback Loop worked,” he told me one evening, his fingers tracing lines on a graph displayed on his tablet. “But it was reactive. Chaotic. The human element—your decisions, her resistance—introduced noise. I want purity. I want to strip away the choice and isolate the sensation itself.”
That’s how I ended up here: the chamber.
It was different from the main lab. A soundproofed cube within a cube, lined with black acoustic foam that swallowed every echo. The air was cool, filtered to a sterile purity that carried the faint scent of ozone and the metallic tinge of my own anticipation. In the center was not a chair, but a modified gynecological table, upholstered in black leather. Restraints dangled from its sides. A Plexiglass shield, currently raised, separated it from a mirrored observation booth. On my side, the only light came from softly pulsing strips along the floor, casting the space in a dim, bloody glow. A large digital timer glowed on the wall, currently blank.
I was already naked. The preparations were ritualistic, clinical. David had fitted me with the gear himself. A heavy, cold steel butt plug, wider than any I’d used before, its base flared and smooth. It was connected by thin, insulated wires to a console I couldn’t see. My nipples were clamped, not with traditional clamps, but with small, vibrating nodes that adhered to the skin. A black silicone gag filled my mouth, held in place by straps around my head. A heavy blindfold, total and complete, plunged my world into void.
“The principle is synaptic reciprocity,” David’s voice said, not from beside me, but from a speaker above. It was clear, disembodied, god-like. “We’ve mapped Chloe’s pleasure thresholds from the last session. Her orgasms have a distinct biometric signature. We’ve programmed the system. Today, you will not control her. You will experience her. Directly. Every peak, every valley. The plug is fitted with micro-transducers. It will deliver electro-stimulation synced to her neuromuscular feedback. The clamps will vibrate in time with her vaginal contractions.”
I tried to speak, but the gag reduced my sounds to a muffled groan. My heartbeat thumped in my ears. This was new. This was total surrender. A shiver, part fear, part dizzying anticipation, traced my spine.
“Chloe is prepped and already in sequence on the other side of the glass,” David continued. His voice was calm, analytical. “You will feel what she feels. The session will last until her system is exhausted, or yours overloads. Beginning in three… two… one.”
A soft hydraulic hum filled the chamber. The table beneath me adjusted subtly, tilting my hips upward, spreading my legs wider and securing my ankles and wrists with soft, unyielding cuffs. I was pinned, open, utterly vulnerable in the dark.
Then I heard it. Not through the speaker, but as a faint, muted thrum through the floor, through the table: a deep, rhythmic vibration. The machines in her chamber had started.
For a moment, there was nothing but the hum and my own breathing, harsh through my nose. Then, a sharp, bright shock exploded in my ass.
It wasn’t pain. Not exactly. It was a lightning bolt of pure, invasive sensation, originating deep inside my rectum where the steel plug met my most sensitive nerves. My body arched against the restraints, a strangled scream trapped behind the gag. It lasted only a second, but it left every nerve alight.
As the aftershocks trembled through me, I felt the nipple clamps come to life. They didn’t just vibrate; they pulsed in a rapid, fluttering rhythm that made my breasts ache and my back strain.
She’s being penetrated, I realized. That shock was the initial entry. These pulses… that’s her cunt stretching around the first tendril.
Another shock, less sharp but longer, a two-second burn that clenched my entire lower body. Simultaneously, the vibrations in my nipples intensified, becoming a hard, driving buzz.
That’s the second one. Anal. They’ve started the double penetration.
A series of smaller, rhythmic jolts began, each one a precise, electric tap against my prostate. The vibrations synchronized into a matched, grinding pattern. The machines inside her were fucking her in a steady, relentless rhythm. In, out. In, out. Each thrust into her pussy sent a corresponding pulse through my clamped nipples. Each push into her ass delivered that bright, shocking jab deep inside my own.
I was a receiver. A hollow vessel being filled with her experience. I felt her resistance in the tight, clenching shocks. I felt her reluctant arousal in the deep, throbbing pulses. My own body began to betray me, responding to the artificial stimulation even as my mind fought to separate itself. My cunt grew wet, the moisture a cold shock against the leather. My ass, stretched by the cold steel, began to ache with a need for more, for the fullness of a real cock, not this punishing current.
The rhythm changed. The shocks became sharper, more frequent, stacking on top of one another until it was a continuous, sizzling wall of sensation in my core. The nipple vibrations became a frantic, screaming hum. Through the floor, I heard—or felt—a low, muffled cry.
She’s close. Her orgasm was building, and the system was amplifying every preparatory tremor.
Then it hit.
The world dissolved into white, silent agony.
It was as if the plug in my ass had become a live wire connected directly to my spinal cord. A sustained, seizing current locked every muscle in my body rigid. It wasn’t a spasm of pleasure; it was torture. Pure, unadulterated neurological overload. The vibrators on my nipples went berserk, a maddening, painful thrumming that felt like they were drilling into my bones. I couldn’t scream. I couldn’t move. I could only exist as a conduit for her climax.
It lasted for an eternity. Sixty seconds. The timer on the wall, unseen by me, counting down each impossible second.
When it stopped, the sudden silence was louder than the pain. My body collapsed, twitching, drenched in sweat. I was sobbing, the tears soaking into the blindfold. The ache between my legs was a throbbing void.
A minute of peace. Just the hum of the air purifier, the ragged sound of my breathing.
Then the shocks started again. Smaller, probing. The vibrations resumed their teasing pulse. She was being worked back up. The machines were relentless, efficient. They would bring her to the edge, push her over, and I would pay the price.
The cycle repeated. Shock, build, shock, build. Then the second cataclysm. This one felt different. The current seemed to dig deeper, finding new, untouched neural pathways to scorch. Her cry, this time, was clearer—a high, broken sound of utter surrender that vibrated through the glass.
I lost count. The sessions blurred into a timeless hell of anticipated agony. My body was a map of her pleasure, each orgasm she was mercilessly driven to tattooing itself onto my nervous system with a brand of electricity. I was floating outside myself, a consciousness anchored only to pain.
At some point, David’s voice returned through the speaker, soft, almost intimate.
“Her capacity is… remarkable,” he murmured, as another wave of building shocks made my toes curl against the restraints. “We’ve refined the stimulus patterns. She’s averaging twelve orgasms per session now. Peak neuromuscular efficiency. And you…” Another low shock, a precursor. “You’ll feel every single one.”
The confirmation sent a new kind of chill through me. Twelve. I’d lost track after four. There were more to come. The system, reading my adrenaline spike, my dread, fed it back to me. The next series of shocks came faster, harder, as if punishing me for my fear.
The next climax, when it ripped through me, was different. Mixed with the blinding pain was a sudden, rogue streak of pure, unholy pleasure. A direct hit to some buried bundle of nerves. It was a flash of color in the white void. A broken, muffled sound that was almost a moan escaped my gag.
The machine learning. Adapting. Finding the cracks in my resolve.
The following build-up was worse. Because now, beneath the dread, a sick, sliver of curiosity unfurled. What would the next one feel like? How would it break me? How would it remake me?
As the familiar, brutal rhythm began again—the probing shocks, the insistent vibrations—I realized with a horror that curled my soul that I was waiting for it. My body, spent and shaking, was already preparing for the next violent peak. I was craving the lightning.
The timer on the wall, had I been able to see it, would have shown there were twenty-three minutes remaining in the session. Twenty-three minutes of Chloe’s translated ecstasy. Twenty-three minutes of my own exquisitely crafted hell.
In the dark, blind and gagged, I let my head fall back. I stopped fighting the restraints. I opened myself to the current. The next shock came, and I embraced the burn.
