Chapter 13: Button by Button
The hum was a new organ.
It lived below Evelyn’s sternum, a lazy, warm coil of wire that pulsed in time with her heartbeat. It had been four days. Four days of waking up with it already buzzing. Four days of drinking coffee, grading papers, brushing her teeth, all underscored by that quiet, unrelenting thrum. It was not pleasure. It was a biological constant, like her body temperature. A sixty-cycle hum of readiness.
She stood before the full-length mirror in her bedroom, trying to tie her silk scarf. Her fingers, usually deft, fumbled. The pattern was wrong. Too constricting. With a sharp sigh, she pulled it off and tossed it on the bed. The blouse beneath—a crisp, white button-up—was already open one button lower than her usual standard. She hadn’t done it consciously. Her hand had just… skipped it.
It’s stuffy in lecture halls, Evi’s voice chimed in, cheerful and invasive. Let them see a little. It’s only fair.
“No,” Evelyn said aloud, to the empty room. Her voice was flat. She reached for the button.
Her fingers refused. They hovered, then drifted to her collarbone, tracing the skin there. A shiver ran through her, unrelated to the room’s temperature. The hum intensified, a soft crescendo.
See? Evi purred. Feels better.
Evelyn closed her eyes, seeking the internal wall. The partition was still there, a distinct, cool barrier in her mindscape. But it felt porous. Thin. Light and sound—Evi’s light, Evi’s sound—leaked through like a faulty membrane. She couldn’t stop the thoughts, but she still controlled the body. For now.
She left the button undone. A small rebellion. Or a small surrender. She couldn’t tell the difference anymore.
The walk to campus was an exercise in sustained tension. Every pedestrian, every rustling leaf, every distant laugh seemed to brush against that live wire inside her. By the time she reached the familiar wood-paneled door of her office, her skin felt two sizes too small. She needed the silence, the dimness, the familiar scent of paper and whiskey. A fortress.
The door was unlocked.
She paused, her hand on the cool brass knob. She always locked it. A habit born of protecting her research, her private thoughts. She pushed the door open.
Ethan Hayes sat in her chair, her high-backed leather throne. He had his feet propped on her desk, next to the half-empty glass of single malt she’d left from the night before. He was scrolling on his phone, the glow painting his calm, unremarkable face in pale light.
The sight shouldn’t have sparked a flutter deep in her chest. It did.
“You’re early,” she said, her voice carefully neutral. She stepped inside, closing the door behind her. The click was final.
“Wanted to check on the subject before the stress test,” he said, not looking up from his phone. He took a slow sip from her glass. The intimacy of the gesture—his lips where hers had been—sent a jolt through her system. The hum buzzed in recognition.
“Stress test?” she asked, placing her leather satchel on the visitor’s chair.
“Your ten o’clock. Introduction to Cognitive Autonomy. Packed lecture hall.” He finally looked at her, his eyes scanning her from head to toe. They lingered on the open button of her blouse. A faint, knowing smirk touched his lips. “Evi’s picking the wardrobe, I see.”
Evelyn felt a blush heat her neck. “It was warm yesterday. I must have forgotten to—”
“You don’t have to lie to me, Professor,” he interrupted, his voice soft. He swung his feet off the desk and stood. He was average height, but in that moment, he seemed to fill the room. “I can feel the dissonance from here. You’re fighting the calibration. It’s causing noise in the signal.” He walked around the desk towards her.
She stood her ground, a feat of will. “My lecture notes are prepared. My cognitive functions are unimpaired.”
“Are they?” He stopped a foot away. He didn’t touch her. He just looked into her eyes, and she felt him pushing. Not a command. A question. A probe.
The partition in her mind flexed. Evi’s presence surged forward, not taking control, but pressing against the membrane from the other side. A giggle echoed in the vault of her skull. He’s here!
Evelyn’s breath hitched. The warm coil in her belly tightened. She felt a dampness that had nothing to do with the room’s temperature. Her professional facade cracked, just a hairline fracture. “Please,” she whispered, not knowing what she was asking for.
“The fight is a waste of energy,” Ethan said, his tone conversational, almost clinical. “You need that energy for your work. For my work.” He reached out and, with a delicate motion, undid the next button on her blouse. “The conflict is degrading your performance. We need to integrate the subsystem more smoothly.”
He closed his eyes for a second, a look of faint concentration on his face.
Inside Evelyn’s mind, it was as if a volume knob, buried deep in her brainstem, was turned. Not all the way. But significantly. A soft, sucking pop, and then a flood.
The hum wasn’t a hum anymore. It was a low, resonant thrum, a bass note vibrating in her bones. Evi’s thoughts weren’t whispers; they were a clear, concurrent channel, running alongside her own.
Ooh, he’s adjusting us! Yes! More, Master! Evi’s voice was bright, unmistakable.
Evelyn gasped, staggering back a step. Her vision swam. The physical sensations were immediate and overwhelming. The silk of her underwear against her skin felt like sandpaper. The air on her newly exposed chest was a shocking, delicious chill. Her nipples tightened painfully against the fabric of her blouse. She was acutely, embarrassingly aware of her own body in a way that had nothing to do with vanity and everything to do with raw, exposed nerve endings.
“What… what did you do?” Her voice was ragged.
“Bumped Evi’s influence to fifty percent,” Ethan said, as if reporting a minor software update. “The partition is still there, but the permeability is increased. She’s not just a release valve anymore. She’s a… constant consultant. You’ll hear her opinions. You’ll feel her drives. They’ll feel like your own. Because functionally, they are.”
It’s so much better! Evi cheered. So much clearer! Don’t you feel clearer, Evelyn?
Evelyn didn’t feel clearer. She felt split, a bicameral parliament where the opposition party was a horny, simple-minded cheerleader with a direct line to her autonomic nervous system. She clutched the edge of the desk, her knuckles white. “I can’t lecture like this.”
“You can,” Ethan stated. He picked up her lecture notes, flipping through them. “In fact, you’ll be better. Less inner conflict. More focus. Evi will handle the somatic distractions.” He looked up, his gaze flat. “You just have to stop fighting her. Let her in.”
He walked to the door, pausing with his hand on the knob. “I’ll be in the back of the hall. Recording. For research.”
He left.
Evelyn was alone with the thrum and the voice. She looked at the clock. Twenty minutes until lecture. She mechanically re-buttoned her blouse, her fingers trembling. The fabric felt oppressive, but covering herself felt like a lie. A denial of the new, pulsating reality.
She gathered her notes, her tablet. The words on the page—“The Illusion of Free Will: External vs. Internal Locus of Control”—seemed to writhe. A bitter, ironic laugh bubbled in her throat, but it came out as a choked sob.
Don’t be sad, Evi cooed. You get to teach all these cute students about minds. And Master gets to watch you. It’s a win-win!
The walk to the lecture hall was a gauntlet. Every passing student, every professor, felt like a potential witness to the civil war inside her. She held her notes like a shield. The thrum between her legs was a relentless, marching beat.
The hall was three-quarters full, the low murmur of a hundred conversations washing over her as she stepped to the podium. The lights were bright. She felt exposed. She focused on the screen at the back, the familiar slide deck waiting.
Then she saw him. Ethan, slouched in the very back row, near the exit. He gave her a small, casual wave. Serena sat beside him, a notebook open on her lap.
The thrum spiked. Her mouth went dry.
“Good morning,” she said, activating her lapel mic. Her voice echoed in the hall, steady, professional. A miracle. “Today we continue our discussion on cognitive autonomy.”
She began to speak. The words came automatically, polished by years of repetition. She discussed Skinner, talked about external reinforcements, moved into modern neural mapping. Her body was on autopilot, a well-programmed machine.
But inside, Evi provided color commentary.
Ooh, that guy in the third row has nice arms. Bet he works out.
She’s totally checking her phone. Rude.
You’re speaking too fast. Relax your shoulders. Master is watching. Smile!
Evelyn’s shoulders did relax. A smile, faint and utterly unnatural, touched her lips. She saw a few students in the front row blink, noticing the shift. She forced the smile away, her heart hammering.
She clicked to a new slide: a diagram of the brain, highlighting the anterior cingulate cortex. “This region,” she said, pointing with the laser, “is crucial for error detection and conflict monitoring. It’s the part of the brain that signals when our actions are out of sync with our intentions.”
As she said the words, a wave of pure, physical need washed over her. It was so sudden, so intense, her knees actually buckled slightly. She gripped the podium. It was Evi, bypassing the partition entirely, sending a direct surge of sheer want through her body. It wasn’t a thought. It was a physiological command.
A soft, involuntary sound escaped her mic—a sharp, stifled gasp.
A few students looked up, concerned.
“Sorry,” Evelyn breathed, shaking her head. “Swallowed wrong.” She took a sip of water, her hand trembling. The cool liquid did nothing. The thrum was a roar now.
You see him back there? Evi whispered, her voice dripping with conspiratorial glee. He’s so powerful. And he chose us. We’re so lucky.
Evelyn tried to focus on the diagram. The colored blobs swam before her eyes. Her own lecture topic was mocking her. Conflict monitoring. Her anterior cingulate cortex was probably lighting up like a Christmas tree, screaming that everything was wrong, while the rest of her brain was being rewired to ignore it.
She pressed on, her voice growing thinner. She talked about lesions, about patients who lost the ability to feel conflict, who followed every impulse without care. “Without that internal check,” she heard herself say, “the concept of self begins to erode.”
Exactly! Evi exclaimed, as if she’d just had a brilliant insight. Less conflict! More self! Well, more of me, anyway.
A student in the front, a keen-eyed young woman, raised her hand. “Professor Reed? You said the anterior cingulate helps us align actions with goals. But what if the goal itself is… externally implanted? Would we even know?”
Evelyn stared at her. The question hung in the air, poignant and devastating. She looked past the student, to the back of the hall. Ethan was leaning forward, elbows on his knees, watching her with rapt, analytical interest. He was waiting for her answer.
The thrum inside her peaked, a cresting wave of heat and pressure. It was no longer just arousal. It was a fulcrum, a point of catastrophic failure. She felt the partition, that already-porous wall, creak under the strain. Evi wasn’t just leaking through anymore. She was shouldering the door open.
Evelyn’s professional smile returned, but this time it was different. It reached her eyes. It was a vacant, pleasant mask. “An excellent question,” she said, her voice smoothing out, losing its strained edge. “The line between external influence and internal desire can become… delightfully blurred.”
She blinked. The word “delightfully” hung in the air. It was not a word she used. It was Evi’s word.
A cold terror sliced through the fog of need. She had spoken without meaning to. The partition had been bypassed, just for a second. Evi had spoken through her, using her voice, her authority.
She saw the student’s brow furrow slightly, confused by the tone.
Evelyn cleared her throat, grasping for control. “That is to say,” she stammered, the professional facade slamming back into place, cracked and shaky, “the philosophical implications are profound. We’ll… we’ll pick this up next time.” She glanced at the clock. “Class dismissed.”
The students, oblivious to the silent collapse happening behind the podium, began gathering their things. The murmur of conversation rose again.
Evelyn didn’t move. She stood frozen, gripping the cool wood, watching them file out. She didn’t see them. She saw only the back row, where Ethan was now standing. He gave her a slow, deliberate nod. An approving nod.
Then he turned and left, Serena following.
The hall emptied, leaving Evelyn alone in the bright, silent space. The thrum subsided, returning to its background hum. The urgent, vicious need receded. But the door in her mind, once firmly shut, now stood ajar. And through it, she could hear Evi humming a happy, mindless little tune.
She had delivered the lecture. She had maintained control. But Evi had spoken. Evi was learning. The partition wasn’t a wall anymore. It was a suggestion.
Her body began to shake, a fine, uncontrollable tremor. She had never felt more divided, or more terrifyingly whole. The battle was no longer about keeping Evi out. It was about figuring out where Evelyn ended and Evi began. And with every passing second, that line, like the concept of self she’d just lectured about, was eroding into nothing at all.
And with every passing second, that line, like the concept of self she’d just lectured about, was eroding into nothing at all.
The last student shuffled out, leaving the vast lecture hall cavernously quiet. Evelyn remained rooted behind the podium, her fingertips tingling against the cool wood. The tremors subsided, leaving a hollowed-out stillness. The only sound was the hum, that constant, taunting frequency in her blood.
He had watched her the entire time. He had heard Evi’s voice leak into her lecture. The memory of his approving nod replayed, a cold spike of shame threading through the warmth he’d programmed into her.
“You looked confused towards the end.” His voice, calm and close, came from the side entrance. He leaned against the doorframe, his hands in his hoodie pockets. “When she used your mouth. That was interesting.”
Evelyn didn’t turn. She stared at the empty seats. “It was an error.” Her own voice sounded distant, mechanical.
“It wasn’t. It was integration.” He walked down the steps, his sneakers scuffing softly on the linoleum. “She’s learning the controls. Faster than I projected.” He stopped beside the podium, looking up at her. “The conflict on your face was perfect data. Real-time cognitive friction.”
She finally looked at him. The ambient light from the screen painted his face in pale blues. He wasn’t smirking. He was analyzing. “It’s degrading,” she said, the word escaping like a confession.
“It’s progress.” He reached out and touched the lapel of her blazer, a casual brush of his fingers. The contact sent a jolt through the constant hum, upgrading it to a sharper, more localized ache. “Your body is calibrated, but your mind is still fighting. That fight is the last piece of noise. We need to eliminate it.”
He said it like trimming dead code. A necessary optimization. The chill in her spine had nothing to do with the lecture hall’s air conditioning.
“How?” The question was a whisper.
“By letting her win a few rounds.” His fingers trailed down from her lapel, over the fabric covering her ribs. He didn’t grab, just traced. “Right here, right now. In your professional space. Where the cognitive dissonance is strongest.”
A soft, breathy giggle echoed inside her skull. Our turn! Evi chirped.
“No,” Evelyn breathed, but it was the old, automatic protocol. A ghost of a refusal.
“Yes,” Ethan said, and it wasn’t a command. It was a simple statement of fact. He withdrew his hand and took a seat in the front row, sprawling comfortably. He rested his phone on his knee, screen facing her. “Continue your lecture. For me.”
Panic, cold and clean, cut through the fog. “The class is dismissed.”
“I’m your only student now.” He tapped his phone. The camera app was open, the red recording light a tiny, accusatory eye. “Pick up where you left off. The philosophical implications of implanted desires.”
This was a new tier of violation. Exposed, she slid her tablet back onto the podium. The slide still displayed the brain diagram, the anterior cingulate glowing. The conflict monitor. She opened her mouth to speak, to summon the practiced, scholarly tone.
Nothing came out.
Instead, a fresh wave of sensation crested over her. It wasn't a slow build. It was a switch flipped. The background hum exploded into a deafening, physical roar. Her knees actually knocked together beneath the podium. A flush of heat crawled from her stomach up her chest, blooming across her throat.
Oops, giggled Evi's voice, clear and bright. Turned it up a bit!
Evelyn gripped the podium's edges, her knuckles bone-white. Her breath came in short, sharp pants she tried desperately to stifle. The low, resonant thrum was now a vibrant, demanding pulse between her legs, a second heartbeat out of sync with the first. It was impossible to ignore, to think through.
"External... influence," she forced out, her voice tight and strained. Her gaze was locked on Ethan's impassive face. "Can… can override… endogenous… reward pathways."
Good start! Now talk about the rewards! Evi encouraged brightly.
Then Evelyn’s own right hand moved.
It detached from the death grip on the podium of its own volition. It floated down, smooth and deliberate, and flattened itself over her lower belly, right through the fabric of her blazer and blouse. The pressure was electric. A ragged gasp tore from her lips, echoing in the silent hall.
Her left hand followed suit, creeping up to rest just below her collarbone. They weren't groping. They were simply resting there, claiming territory. Her own hands, warm and traitorous.
"Evi," she whispered, a desperate plea to the empty air.
I'm right here! Evi replied, cheerful. You're so tense. Let me help.
Evelyn's right hand began to move in a slow, small circle over her abdomen. The touch was light, almost casual, through the layers of clothing. It sent rivulets of fire straight down. Her left hand mirrored the motion, a soft, maddening caress just above her breast.
She was touching herself. In her lecture hall. Under the fluorescent lights. While a student watched and recorded.
"The… the subject," she choked out, trying to anchor herself in the academic text, "may perceive the… the implanted goal as… as autonomous." The words were halting, shredded by the rhythmic, gentle motion of her own palms. The physical distraction was absolute, a brilliant, cruel sabotage of her higher thought.
Ethan watched, his expression one of fascinated curiosity. He zoomed in with his phone slightly. "Keep going."
Evelyn's hands continued their gentle, wandering exploration. They slid an inch lower, an inch higher. They weren't frantic. They were playful. Taunting. A live demonstration of a mind divided. Her face was a mask of mortification, eyes screwed shut, but her body under her clothes was responding, warming, betraying her with every pass of her own fingers.
"Conflict…" she panted, "becomes… itself… a source of…" She couldn't finish. A small, helpless sound escaped her as her right hand dipped lower, pressing firmly against the apex of her thighs. The bolt of sensation was blinding. Her eyes flew open, wide with horror.
Evi’s laughter tinkled in her mind. See? Doesn’t that feel better than talking?
Tears of pure, undiluted humiliation welled in Evelyn’s eyes, blurring the image of Ethan in the front row. She was lecturing on cognitive conflict while her own hands worked to destroy her last vestiges of it. The contradiction wasn’t just philosophical. It was flesh and blood and unbearable sensation.
“The subject,” Ethan prompted, his voice soft. “What does the subject become?”
Evelyn stared at him, her hands still moving, her entire body humming with a degraded, manufactured need. The answer was in his eyes, in the cool lens of the phone, in the traitorous warmth of her own touch.
She understood. She was no longer the professor. She was the lesson.
A single tear tracked its way through her powder, cutting a clean line down her cheek. She opened her mouth. A wet, broken sob came out. It was the only lecture she had left.
