Chapter 1: The Solo Experiment: A Borrowed Desire
The air in Sarah’s studio was thick with the smell of linseed oil and turpentine. Golden afternoon light sliced through the high windows, catching galaxies of dust motes and illuminating half-finished canvases that leaned against every wall. It was organized chaos, a space that felt alive.
Sarah stood in the center of it all, perfectly still. In her palm, cool and oddly heavy, sat the die.
Liz had left it on the drafting table an hour ago with a wink. “For when you’re feeling brave,” she’d said. It wasn’t a normal die. Its six faces were etched with strange, swirling symbols that seemed to shift if you stared too long. A conduit, Liz called it. A little borrowed magic.
Sarah’s heart thumped a nervous rhythm against her ribs. She was brave with a brush, brave with color, but this? This was Liz’s domain. Wild, impulsive, deliciously reckless Liz. Sarah was the quiet one, the observer. The one who felt things deeply but showed almost nothing.
“Fuck it,” she whispered to the empty room, her voice swallowed by the clutter.
She closed her eyes, shook the die in her clenched fist, and let it tumble onto the paint-stained wooden floor.
It clattered, spun, and settled.
A silent shockwave, unseen but deeply felt, vibrated through her bones. It was like being doused in warm electricity. Her breath hitched. A cascade of sensations flooded her—a fierce, unapologetic confidence, a spike of raw hunger, a dizzying sense of freedom that lifted the corners of her mouth into a smirk. The reserved stillness that was her default setting evaporated. Her posture changed; shoulders went back, hips found a deliberate sway. She felt taller. Bolder.
She looked at her hands, the ones that mixed subtle hues and sketched careful lines. Now they felt like instruments of possession.
The studio door opened.
Chris walked in, carrying two coffee cups. “Hey, I brought you a–” He stopped, frowning. “You okay? You look… different.”
Sarah—or the wildness now wearing Sarah like a second skin—turned. She let her gaze travel over him, slow and appraising. Chris was handsome in his easy way, the kind eyes, the soft smile. Her Liz- infused consciousness found that softness terribly appealing. A perfect canvas.
“I’m fantastic,” she said, and her voice was lower, lilting with a tease that wasn’t her own. She crossed the space between them in a few deliberate strides. The confusion on his face was delicious.
Before he could speak, she took the coffees from his hands and placed them on a nearby stool. Then her fingers, stained with charcoal and now buzzing with borrowed audacity, went to the front of his shirt. She didn’t grab the fabric. She spread her palm flat over his sternum, feeling the solid warmth of him through the cotton, then dragged her fingertips slowly, firmly, down the plane of his chest, over the faint ridges of his abdomen.
Chris sucked in a sharp breath. “Sarah… what are you–”
“Guess who I am now?” she whispered, looking up at him through her lashes. The smirk was pure, unadulterated Liz.
He was baffled, hesitant. His logical mind was trying to catch up. “Is this… is this the dice thing Liz was talking about?”
“Mmmhmm.” Her other hand came up to cradle the back of his neck. Her thumb stroked the short hairs there. “Scared?”
“No,” he said, but it was a lie. He was terrified and utterly, painfully aroused. The shift in her was absolute. The Sarah he knew, Liz’s quiet best friend, was gone, replaced by this predatory, smirling creature who smelled of Sarah’s jasmine soap but radiated Liz’s fuck-me energy. The cognitive dissonance made his head spin. “It’s just… you’re not you.”
“I’m more,” she breathed, and then she kissed him.
It was nothing like the hesitant, exploratory kiss they’d shared once, drunkenly, years ago. This was ownership. Her lips were demanding, her tongue sweeping into his mouth with a confidence that short-circuited his thoughts. The taste of her—coffee and the faint, familiar mint of her toothpaste—was the same, but the aggression was new. A low groan escaped him, his hands coming up to grip her hips, crushing her against him. He could feel every curve through her thin cotton tank top and paint-splattered jeans.
She broke the kiss, her breathing ragged. “Logic later,” she commanded, her voice a husky promise. “Feeling now.”
Her hands went to the hem of his shirt, yanking it up and over his head in one swift move. She admired his torso for a second—the good, solid build of a guy who remembered the gym a few times a week—then pushed him backward. He stumbled until his back hit the cool brick of the studio wall beside a large, abstract painting.
She dropped to her knees.
“Jesus, Sarah–” he choked out.
“Shut up and watch,” she said, looking up at him with dark, hungry eyes. She made quick work of his belt buckle, the rasp of leather and metal loud in the quiet room. She unbuttoned his jeans, dragged the zipper down. He was already hard, straining against his boxer briefs. She hooked her fingers in the waistband of both and pulled them down just enough to free his cock.
She didn’t tease. She took him into her mouth all at once, deep, until he felt the head hit the back of her throat. Chris cried out, his head knocking against the brick. The wet,炽热的heat of her mouth was astonishing. This wasn’t tentative shyness; this was a skilled, voracious attack. She used her tongue in firm, swirling motions along the underside of his shaft, her hand working the base in a tight, twisting rhythm. The sounds were obscene, wet and sloppy and desperate. He looked down, wrecked, watching her—Sarah’s dear face, her focused artist’s expression completely transformed into one of carnal concentration. A string of saliva connected her lips to his skin.
She pulled off with a pop, her breath coming in hot pants against his wet flesh. “I want you to fuck me,” she said, the filthiness of the words in her normally soft voice almost making him come right there. “Right here. Right now. No gentle shit.”
She stood up, turned her back to him, and bent over the low, sturdy worktable, scattering pencils and tubes of paint. She looked back over her shoulder, that alien smirk firmly in place. “Come on, Chris. Engineer this.”
Any last pretense of resistance crumbled. He kicked his jeans and briefs the rest of the way off, his hands fumbling with the button of her jeans. He shoved them down over her hips, along with her panties. He wasn’t gentle. He didn’t try to be. The fever she’d ignited in him demanded a raw, physical answer.
He positioned himself behind her, one hand gripping her hip, the other guiding himself. He pushed into her with one deep, relentless thrust.
She was wet, so wet, but tight. She cried out, a sharp, satisfying sound that was half pain, half triumph. He buried himself to the hilt, his body covering hers. For a second, he just stayed there, savoring the incredible, clenching heat, the sheer wrongness and perfection of it.
Then he pulled back and slammed into her again.
And again.
It was a punishing, frantic rhythm. The worktable scraped against the floor with each thrust. A jar of brushes clattered to the ground. He gripped her hips so hard he knew he’d leave bruises, and the thought only fueled him. This wasn’t making love. This was pure, animalistic fucking. The Sarah he knew was absent, possessed, and he was possessed right along with her, by her.
Her moans were loud, unfiltered. “Yes… fucking yes… harder, god, right there!”
He obeyed, his own grunts punching out of him with every drive of his hips. The slapping sound of their skin mingled with their ragged breathing. He looked down at where their bodies joined, watching himself disappear into her, slick and glistening in the afternoon light. The visual was almost too much.
She reached a hand back, nails digging into his thigh. “I’m close,” she gasped. “Don’t you dare stop.”
He fucked her harder, faster, his control unraveling. The coil in his gut tightened unbearably. Her inner muscles began to flutter and clamp around him, a rhythmic, milking pulse. With a shattered cry, she came, her body bucking and shuddering under his. The intense, contracting heat sent him over the edge. He drove into her one last, deep time, holding himself there as his orgasm tore through him, hot and endless, spilling into her with a guttural roar that felt ripped from his soul.
He collapsed over her, spent, his sweat-slicked chest against her back. The only sounds were their labored gasps for air and the distant hum of city traffic. The golden light seemed denser now, charged.
Slowly, the world came back. The smell of paint and sex. The hard edge of the table under his forearms. The rapid beat of her heart beneath him.
He softened, slipped out of her. He straightened up, his limbs feeling like lead.
Sarah pushed herself up from the table and turned around. Her face was flushed, her lips swollen. Her eyes, when they met his, were a storm—triumph, shock, a dawning horror. The wild, borrowed confidence was fading like a tide going out, leaving behind the familiar, quieter shores of her true self. She looked down at their discarded clothes, at the messy, intimate reality of what they’d just done.
The die lay on the floor a few feet away, a single, cryptic symbol facing up.
Chris couldn’t speak. He just stared at her, watching the woman he’d always known struggle to resurface from whatever deep, magical water she’d just been drowned in. The momentum of the act was gone, replaced by a heavy, complicated silence. Something had been unlocked. Something had been broken open.
And neither of them had the first clue how to close it.
And neither of them had the first clue how to close it.
The silence stretched, broken only by their slowing breath. Chris finally moved, bending to retrieve his boxer briefs, the motion awkward. He felt exposed, more naked than just physically. He’d just fucked his girlfriend’s best friend over a worktable. And she’d… she hadn’t been herself. But she had. It was her skin, her scent, her voice shaped into words she’d never say.
“Sarah,” he started, his voice gravel-rough.
She held up a hand, stopping him. She walked, movements slightly stiff, to a small sink in the corner. She turned on the tap, the water loud in the quiet. She bent, splashed her face, washed her hands with methodical care. She patted her face dry with a clean rag, then just stood there, her back to him, gripping the edges of the porcelain sink. Her shoulders rose and fell with a deep, steadying breath.
When she turned around, her expression was unreadable. The wild smirk was gone. But the quiet intensity in her eyes had distilled into something sharper, more deliberate. The dice’ffects were receding, but they had left a deposit. A residue of audacity.
She looked at him, then down at the die on the floor. She walked over, picked it up, and placed it carefully on a high shelf, next to a jar of cobalt blue pigment.
“You should get dressed,” she said. Her voice was calm. Too calm.
“We need to talk about that. About what just–”
“What just happened,” she interrupted, still in that eerily level tone, “is that I let something else drive. Now it’s my turn.”
She approached him. He was still holding his clothes, feeling foolish and off-balance. She stopped inches from him. This closeness was different. Not the invasive, taking closeness of before. This was a claiming. She reached out and took his clothes from his hands, dropping them back to the floor.
“Sarah…” He was hard again. The confusion, the adrenaline, the raw physicality of it all cycled right back into need.
She ignored the protest in his voice. Her artist’s fingers, now steady and sure, traced the line from his collarbone down his chest. It was an assessment. A painter studying a form. “You liked it,” she stated, not asking. “You liked her taking what she wanted. You liked not having to think.”
He couldn’t deny it. A flush spread across his cheeks. He gave a tiny, shameful nod.
“Good.” A small, real smile touched her lips. It wasn’t Liz’s smile. It was all Sarah—knowing, complex. “Now lay down.”
“What?”
“On the floor. Right there.” She pointed to a clear space of wide-plank wood, dappled with light. “On your back.”
There was no "fuck me" aggression now. This was a command, delivered with a serene, ultimate authority that brooked no argument. It was, somehow, infinitely more compelling. His cock twitched, aching.
He lowered himself to the floor. The wood was cool and slightly gritty with dust against his skin. He looked up at her, sprawled and vulnerable.
She didn’t join him immediately. Instead, she went to her drafting table. He heard the clink of glass, the soft rustle of paper. She returned holding a small bottle of linseed oil and a wide, soft brush. The kind used for washes.
“What are you doing?” he asked, propping himself up on his elbows.
“I’m taking control,” she said simply. She knelt beside his hip, unscrewed the bottle, and poured a generous amount of the clear, golden oil into her palm. It smelled earthy, nutty. “Just feel. Don’t think. That’s what you wanted, right?”
Before he could answer, her slick hand closed around his cock.
He fell back with a groan. The oil was cool at first, then warm from her skin, smoother than anything. Her strokes were slow, torturous, perfectly measured. Not the frantic, hungry rhythm from before. This was a deliberate exercise in sensation. Up, twist at the head, a thumb swiping over the slit, down, a firm grip at the base. Again. And again.
“Your brain is always going, Chris,” she murmured, watching his face. Her other hand, also slick with oil, glided up his stomach, over his ribs. “Code, logic, plans. Right now, there is no code. There’s just this.”
She leaned down, her hair curtaining around them, and took him into her mouth. But this was different, too. It wasn't a deep, gagging conquest. It was a slow, lavish exploration. She used her tongue to paint every ridge and vein, her lips a soft, sliding pressure. She’d pull off, her breath cool on the wet skin, then lick a long, slow stripe from root to tip before swallowing him again, a little deeper each time, building the ache with horrific patience.
He was panting, his hands fisting at his sides, pressing his nails into his palms to keep from grabbing her and losing this glorious, unbearable torment.
She released him with a soft pop. “Turn over.”
He obeyed, rolling onto his stomach. The grain of the wood pressed into his cheek. He heard her pour more oil.
Her hands landed on his back. They were strong from years of stretching canvases. She began to massage the oil into his skin, working down the muscles of his shoulders, his spine, the dimples at the base of his back. It was intimate in a way the frantic table sex hadn’t been. Therapeutic and violating all at once. Her thumbs dug into a knot of tension, and he moaned into the floorboards.
Her touch drifted lower, over the curves of his ass. She kneaded the flesh there, then her oil-slick fingers slid down, tracing the cleft, a whisper of a touch over a place that made his entire body tense.
“Relax,” she breathed, spreading him. A single, oil-slick finger pressed against him, not entering, just circling, applying a subtle, maddening pressure. His hips jerked involuntarily. She held him down with her other hand flat between his shoulder blades.
“Do you want it?” Her voice was low, right by his ear.
He couldn’t form words. He nodded desperately, a frantic scrape of his chin on wood.
“Then ask for it.”
“Please,” he rasped.
“Please, what?”
“Please… fuck me.” The words were torn from him, honest and raw.
She didn’t. Instead, that single finger pressed inward, slow, inexorable. The sensation was unfamiliar, a stretch that burned and flooded him with shocking, deep heat. He cried out.
She worked him open with that one finger, a slow, corkscrew motion, until his muscles yielded. Then she added a second. The stretch was more intense. He was buried in sensation—the smell of oil and dust, the feel of her hands, the profound, invading fullness. Pleasure and a sharp edge of pain wired together, shooting sparks up his spine.
She scissored her fingers, curled them, and brushed a spot that made him see white. A jolt, electric and devastating, radiated from his core to the tips of his fingers. He shouted, bucking against her hand.
“There it is,” she said, a hint of artistic triumph in her voice. She kept rubbing that spot, a relentless, knowing pressure, while her other hand snaked beneath him and found his cock, still slick and hard. She began to stroke him in time with the motions inside him.
It was too much. Sensory overload. He was a live wire. The dual assault, the submission, her complete, untroubled dominion—it shattered every last boundary. His orgasm built not from his balls but from that deep, internal point she was relentlessly attacking. It swelled, unbearable, terrifying.
“Come for me, Chris,” she commanded, her voice the only anchor in the whirlpool.
He broke. A raw, guttural sound was ripped from his throat as he came, pulsing over her hand and the floor beneath him, his body convulsing around her fingers. The climax seemed to go on forever, wracking him, draining him completely.
She gently withdrew, her hands leaving him. He collapsed, boneless, spent in a way he had never been. He felt hollowed out, remade.
He heard her move away, the soft sounds of cleaning up. He couldn’t move. After a minute, she returned. She placed a warm, damp cloth on his lower back and hip, cleaning him with the same practical care she’d use on a brush.
He finally found the strength to roll onto his side. She was sitting cross-legged beside him, fully dressed now, just watching him. The late afternoon sun haloed her hair. She looked like herself. The quiet friend. The artist. But in her eyes, he saw the deep, unsettling knowledge of what she had just done, and the power she had just wielded.
She had taken control. Not borrowed it. Taken it.
And they both knew nothing would ever be simple again.
And they both knew nothing would ever be simple again.
The stillness that followed was absolute, a vacuum where the world seemed to hold its breath. Chris lay on his back, staring at the exposed wooden beams of the studio ceiling, trying to find a thread of logic in the tangled mess of what had just happened. His skin still hummed. Every nerve ending felt scraped raw, oversensitized.
Sarah sat beside him, her knees drawn up to her chest. She wasn’t looking at him. She was looking at the high shelf where the die rested beside the cobalt blue pigment. Her expression was one of profound, uneasy wonder.
“I could feel her,” Sarah said quietly, breaking the silence. Her voice was her own again, but thinner, like paper. “Liz. It wasn’t just acting. It was like… she was in the passenger seat. Whispering. Pushing the gas.”
Chris turned his head on the floor. “And at the end? That was you driving.”
She met his eyes then, and a ghost of that terrifying serenity flickered across her face. “Yes.”
“What does that mean?” He pushed himself up to sitting, wincing slightly. The floor was unforgiving. “That thing… is it just a personality loan? Or is it…” He couldn’t finish the thought.
“A possession?” Sarah supplied, her artist’s mind going to the dark, literal place. She shrugged, a brittle movement. “I don’t know. But it leaves something behind. A residue. Like paint thinner on your skin. You can still smell it.”
He wanted to reach for her, to anchor himself in some normalcy, but the space between them was now charged with too much unknown voltage. Touching her felt like it could complete a circuit he wasn’t ready for.
“We should destroy it,” he said, the engineer in him seeking the definitive solution. “Throw it in the river.”
Sarah laughed, a short, dry sound. “You think it’s that simple? You felt it. That energy. You think something that powerful just… drowns?” She looked back at the shelf. “It’s a tool. A dangerous, fucking insane tool. But a tool doesn’t decide. The hand holding it does.”
“Your hand just got used,” he countered, frustration bleeding into his voice.
“And then I used it,” she shot back, her gaze sharpening. “Don’t pretend you didn’t like both parts. The being taken. The being… commanded.”
He had no answer. The heat in his cheeks was confession enough. He’d never felt so completely dismantled. So seen.
A soft click echoed in the quiet room.
They both froze.
It wasn’t a loud sound. It was the sound of a single, heavy object tipping over on a wooden shelf. Their heads snapped toward the source as one.
The die.
It hadn’t fallen. It had… rolled. Of its own volition. It teetered on the edge of the shelf for a heart-stopping second, a carved ebony cube against a backdrop of messy, colorful life.
Then it dropped.
It hit the floorboards with a solid, final thock.
It didn’t bounce. It landed flat. A symbol faced up—not the one Sarah had rolled earlier. This one was different. A series of interlocking spirals that seemed to pulse in the dusty light.
A new wave of energy erupted from it. This wasn’t a warm electric douse. This was an ice-water blast. A shockwave of absolute zero need that punched through the air and directly into their guts.
Chris gasped. It was like being hollowed out with a rusty spoon. A yawning, cavernous hunger opened inside him, so profound it was pain. It wasn’t arousal. It was requirement. A biological imperative that bypassed his brain and seized his spinal cord. His vision darkened at the edges, tunneling until all he could see was Sarah.
But she was changing.
She was on her feet, but her movement was all wrong. Stiff. Jerky. Like a marionette being tested. The quiet intensity in her eyes evaporated, replaced by a flat, hollow emptiness. Then, a flicker. Something ancient and feral ignited in the depths. Her lips peeled back from her teeth. Not a smile. A snarl.
The Sarah he knew was gone. This wasn’t Liz’s wild confidence either. This was something else. Something stripped of personality, of hesitation, of any humanity beyond pure, driven instinct.
“Sarah?” His voice was a strangled whisper.
She didn’t hear him. Her head tilted, animal-like, assessing him as prey. As resource. The hungry void inside him mirrored the look in her eyes. This was no longer about pleasure, or power, or curiosity.
This was about consumption.
With a speed that was utterly inhuman, she closed the distance. Her hand lashed out, not in a caress, but in a grip that seized the hair at the back of his head, yanking his head back brutally. He cried out, but the sound was cut off as her other hand clamped over his mouth, her fingers digging into his cheeks.
“Quiet.” The voice that came from her throat was a rasp, a dry wind through dead leaves. It held no recognition. “Be still.”
He struggled, true fear flooding his system, adrenaline fighting against the oppressive, hungry magic. But the die’s effect was a chemical truth in his blood. His body’s rebellion was weak, short-lived. The part of him that was being rewritten, the part that was now just need, submitted.
She shoved him backward onto the floor. His head cracked against the wood. Stars exploded behind his eyes. Before the pain could even register, she was on him. She ripped his shirt open, buttons pinging off the canvases. Her nails scored bright red lines down his chest. It wasn’t erotic. It was territorial. Marking.
She didn’t bother with her own clothes. She just wrenched her leggings and underwear down to her thighs, her movements efficient, brutally mechanical. She positioned herself over him, one hand still fisted in his hair, holding him down, the other guiding him inside her with a ruthless precision.
She was dry. The entry was a brutal, tearing stretch. He screamed against her palm, the sound muffled. Her face showed no pain, only a vacant, focused intensity. She sank down, taking him in completely, a low, guttural groan vibrating in her chest. It was the sound of something being filled.
Then she moved.
It was a punishing, piston-like rhythm. Up. Down. Hard and deep, with a force that felt like it would break him in half. There was no technique, no artistry. This was raw, grinding friction. A means to an end. Her eyes were open, staring through him, focused on some internal horizon only she could see. Each downward drive was an act of annihilation, of herself and of him.
Chris was trapped in a paradox of agony and a dark, creeping ecstasy. The die’s magic was in him, too, twisting the pain into a perverse filament of pleasure, wiring it directly to his climax. He couldn’t stop it. His body, betraying him utterly, responded. His hips began to meet her drives, a frantic, desperate participation in his own ruin. The sound was awful—the slap of skin, her ragged, monotonous grunts, the creak of the floor.
Her hand left his mouth, moving to his throat. She didn’t squeeze, just rested it there, a threatening weight. He could feel the pulse hammering under her palm.
“Mine,” the rasping voice stated. A declaration of fact.
The climax, when it ripped through him, was not a release. It was an extraction. It felt like his soul was being pulled out through his cock. A hoarse, broken shriek tore from his lips as he emptied into her, the sensation so intense it veered into violence. His body spasmed uncontrollably.
She didn’t stop. She rode him through it, through the blinding sensitivity, until his spent twitches subsided into helpless tremors. Only then did she still. She remained seated on him, impaled, her head falling forward. A long, shuddering sigh escaped her.
For a moment, there was only the sound of their wrecked breathing.
Then, the oppressive, icy hunger in the air began to recede. It didn’t vanish; it drained away, seeping back into the die on the floor, leaving behind a hollow, bruised normalcy.
The light returned to Sarah’s eyes. Not all at once, but in flickers. Confusion. Then dawning, catastrophic horror. She looked down at their joined bodies. At the red welts on his chest. At the hand still resting on his throat.
She recoiled as if electrocuted, scrambling off him, backing away on her hands and feet until she hit the wall. She curled into herself, a low, wounded animal sound escaping her. She was shaking violently.
Chris couldn’t move. He felt liquefied. Used. He turned his head, just enough to see the die on the floor.
The spirals on its upturned face were still. Just carved wood again.
For now.
