Edna Curtis’s front door offers no challenge. The latch surrenders on the first try, barely a click. Deadblot isn’t thrown. Dumb bitch, the young woman thinks. The moon drags a rectangle of light across the entryway tiles, and the Intruder glides through it, head ducked, face angled down. Her shadow looms tall behind her. Shoulders block half the doorway, arms coiled tight against her torso, gym-swollen and deliberate. No one waits up. No dog. No warning. Carpet drinks her footfalls.

Familiar layout, unfamiliar scent. The house wants to close in around her, but muscle memory, the kind built in years of locker rooms, gyms, and rented rooms, navigates the darkness without apology. Straight through the foyer. Left at the stairs. The air holds a note of lemon floor cleaner, a hint of something floral beneath. A painting slumps on the wall: overwrought landscape, sunless. Living room ahead, kitchen to the right, the glow of a digital clock seeping over the countertop. 2:11 a.m.

A pause in the gloom. Shoulders square up. She listens. Houses breathe. This one holds its breath. The silence crushes ... A sound. Barely a thread, but sharp enough to carve through the hush. Not a footstep, not the metallic whine of pipes. A moan, stretched thin, breaking into smaller, helpless notes. Bedroom, second floor, door ajar and inviting.

Her lips tug sideways, not quite a smile.

The stairs complain, but only in the softest whimper. One at a time. Each step calculated, no weight wasted. The bulk of the young woman moves with unexpected grace, as if the heaviness exists only to intimidate, never to slow. At the landing, she stops again. The sound below grows louder, clear now: a woman’s voice, spooling through muffled whimpers and gasps. Punctuated by short, sharp breaths.

She imagines the scene on the other side of the door. Not out of prurience. Out of necessity. Preparation.

She moves up the hallway, hand brushing against the wallpaper for bearings. The walls narrow around her. At the far end, in the anemic glow of the nightlight in an outlet, the bedroom waits. The door stands open enough. The Intruder’s chest brushes the frame as she passes through.

Inside, Edna Curtis writhes in the center of a queen mattress, quilted comforter shucked halfway down. Legs bare, knees drawn up, foot scrabbling at the sheets for traction. Right hand works furiously beneath the elastic of pale pink underwear, left hand mashed over her face, smothering sound, not quite succeeding. The pulse in Edna’s throat jumps and retreats with every gasp.

From the dark, the intruder catalogues: Edna’s hips, rounded and soft but desperate to press higher; the way her stomach contracts with each stifled breath; the panicked rhythm of her fingers, frantic and clumsy. The face—she recognizes it from faculty photos, but those never captured this slackness, this surrender. The laugh lines dig deeper now, mouth open and bitten red.

No signs of a partner. No backup. Even the faint blue light of a phone left face-up on the nightstand fails to summon rescue. Edna rides the edge alone, oblivious.

A shock of satisfaction courses through the Intruder. Not arousal—something colder, cleaner. This is the moment she engineered.

She keeps her body low and moves around the foot of the bed, boots ghosting over the hardwood. Edna’s eyes clamp shut, tears beading in the corners, chest heaving, hips bucking. She arches, and the duvet slips lower, exposing more thigh, a flash of stomach, the swell of a breast, and a fat, stiff nipple, a pink and puffy areola, under stretched-out cotton. For a moment, the woman on the mattress looks childlike, lost in her own need, defenseless as a cut flower.

The Intruder fills her lungs, savoring the hush before the rupture. She towers at the edge of the bed, arms folded, breath steady, heartbeat slower than the trembling form before her. Her own breasts, compressed beneath a tactical sports bra and dark T-shirt, ache with their weight, a contradiction sewn into her DNA and trained into compliance.

With her voice rising, Edna edges toward climax and breaks off into a shuddering whine. The Intruder waits for the perfect cadence. A vulnerable note, a last gasp, and drinks it in.

She shifts her weight, toes flexing in thick socks. A wood plank groans underfoot, sharp and sudden, no longer an accident but a signal. Edna freezes. The silence tightens into a garrote.

For a second, the only sound is the shivering of Edna’s breath, trapped behind her bitten lip. Sightless at first, Edna’s eyes snap open in a second, wide and animal. She doesn’t scream. The moment before she does, the Intruder locks eyes with her, all the promise of violence condensed into that silent transaction.

Edna’s hand drops from her underwear, leaving it twisted and wet against her thigh. She claws for the covers, but the quilt tangles around her knees. The Intruder simply stands there, backlit by the low light, casting a shadow long enough to swallow the woman and the bed together.

No words yet. The presence alone speaks enough. This is a hunt. This is what the Intruder came for.

The standoff stretches. Edna, eyes blown wide, hands knotted in the sheets. The Intruder waits, hands on hips, feet planted below the edge of the mattress. There’s an unnatural bulge in her jeans. Edna’s chest hitches, breath locked in her throat. The covers barely shield her, and the trembling of her limbs telegraphs every pulse of panic.

“Who...” Edna’s voice cracks. She can’t finish.

The Intruder’s pale, blue eyes stare through her. No need for introductions. No need for names. A step closer, and the mattress sags under the new weight, even before she touches it. She keeps her voice flat, lower than Edna’s own ... monotone that drills through the panic.

“Quiet,” she says.

Edna obeys, soundless except for the whimper she can’t swallow. The Intruder leans over her, arms caging in, and lets her mass do the rest. For a moment, neither of them moves. Reaching over, she turns on the light on the nightstand, an orange, muted glow.

The girl puts her hand between the older woman’s legs. Thrusting her strong girl finger inside the older woman, holding the panties out of the way with her thumb, brutalizing Edna’s clit. When she adds a second and a third finger, Edna rolls through a massive climax.

The Intruder smiles, withdraws her hand, and works the leather belt free in a single motion, whipcrack, a metallic clink. The sound snaps Edna from ecstasy back to her body. The buckle glimmers in the salt lamp’s light, promise of metal and violence. The buckle ... western-style, oval, oversized, a rearing horse on one side, with a hook on the other. Edna’s eyes dart to the belt, back to the Intruder’s hands, and back to the door, calculating escape.

The Intruder grins, humorless. She knows every calculation before Edna can finish it. A slow zip from her jeans, and she yanks them down to mid-thigh. The strap-on juts forward, black and obscene, already glistening with something synthetic. She grips the shaft, making a show of adjusting it. The head presses against her palm, solid as wood.

“Please,” Edna whispers, voice thin as sewing thread. “Don’t...”

She doesn’t finish.

The Intruder waits until Edna stops making noise, seizes the duvet, and rips it away. The covers tangle around Edna’s ankles, leaving her exposed ... pale skin blotched with passion’s heat, underwear streaked damp, thighs trembling. Edna brings her knees together, arms folded in a futile shield.

The younger woman lunges. The mattress groans as her weight crashes down. One hand pins Edna’s wrists above her head, the other grabs a fistful of hair, jerking her face upward. The sharp snap of Edna’s neck stuns her into silence. The Intruder’s mass sinks Edna half a foot deeper into the bed, her free hand twisting Edna’s gaze toward her own.

Edna thrashes, weak, desperate. She jerks her head side to side, tries to bite, but the Intruder only laughs, a deep, guttural, growling chuckle. With her face inches from Edna’s, she hisses, “You make a single sound, I’ll break your lovely jaw.”

Edna whimpers, but it’s all breath, no voice.

The Intruder shifts her grip, trapping both wrists with one hand. With the other, she hooks a finger under the elastic of Edna’s underwear and yanks. The fabric cuts into soft flesh and gives way, splitting at the seam. Edna kicks, tries to twist her body out from under, but the Intruder’s legs cage her in. There’s nowhere to go. The mattress is quicksand, every effort only drawing her deeper.

The strap-on meets skin. Edna’s thighs clamp together, shaking. The Intruder runs the head up and down the crease, slow at first, as if savoring the fear. Edna’s eyes slam shut, lips peeled back, breath coming in ragged, uneven gasps.

Then, panic floods in. Edna arches her back, flailing. She manages to slip a hand free and swings it wildly at the Intruder’s face. Nails scrape across her cheek, leaving red lines.

The Intruder reacts instantly. Her free hand whips around and slaps Edna, open-palmed, right across the cheek. The sound cracks through the room, echoing off the walls. Edna’s head snaps sideways, lips splitting on the impact. Blood beads at the corner of her mouth, bright and thick.

She tries to scream, but the breath has left her lungs. Her whole body locks up, arms and legs rigid, shock overriding any fight left in her. Tears spring to her eyes, sudden and hot.

The Intruder grips her hair again, yanking her upright. “Didn’t I say quiet?” Her voice drips contempt.

Edna shudders. All defiance leaks out, replaced with a hollow, shaking fear. The Intruder releases her grip and lets Edna sag back, neck at a bad angle, eyes unfocused.

She lets Edna feel her weight, chest to chest, the strap-on pressing into soft belly, hard enough to hurt. She bends close, her lips almost at Edna’s ear.

“Don’t make me do it again,” she whispers.

Edna lies still, panting. The hope of escape flares, gutters out. The Intruder can see it die behind her eyes.

She’s ready. She’s broken.

The room swims in low light, shadows stitched with the sounds of Edna’s shaky breaths. The Intruder tightens her grip, palm slick with sweat and the barest tremble of adrenaline. She never lets Edna forget the pressure on her wrists, the cold vinyl strap-on pressed between their bodies, the weight of one human crushing another into memory foam and white sheets.

“This is happening,” she says. Her voice is flat, almost bored, but the force behind it carries more threat than the slap. “Don’t make a fucking sound or I’ll hurt you more.”
