A public display of affection

The zipper's rasp is deafening in the quiet hallway. Your sister's fingers are cool against your burning skin as she pulls your pants and boxers down just enough to free you. The fluorescent light is unforgiving, stark. It paints everything in a sickly, electric sheet.

From the far end, a low groan echoes, followed by Kiersten's breathy gasp. They are a frantic, blurred rhythm against the lockers.

Bell doesn't look at them. She looks up at you, her hazel-brown eyes holding a challenge that makes your stomach tighten. Her warm breath mists your skin. "Watch them," she murmurs, her voice a rough whisper. "Remember, what they're doing is completely natural."

Then her mouth is on you, and every thought short-circuits.

The heat is absolute. The wet, slick pressure is a shock that races up your spine, pulls a choked sound from your throat. Your hands fly out, bracing against your own set of hallway lockers. The ridges of the vents dig into your palms. Your knees feel liquid.

She works with a confident, devastating rhythm, one hand cupping your prodigious balls, the other steadying herself on your thigh. Her eyes are open, watching your face. A strand of her hair, damp with sweat from her earlier workout, sticks to her cheek.

You try to look away, to find somewhere neutral to fix your gaze - the ceiling tiles, the fire alarm, anything. But your eyes are dragged back down, to the sight of her lips stretched around you, to the hypnotic motion of her head. And beyond her, to Colton and Kiersten.

He had her pinned high against the lockers, her legs hooked around his waist. Her pleated skirt was rucked up around her hips, a crumpled banner of surrender. His thrusts were sharp, athletic; the metal lockers behind her head rattled with every drive.

“Please, Colt,” Kiersten moaned, her voice slicing through the wet sounds of Bell’s mouth. “Don’t pull out. I need it so bad.” Her fingers clawed at his letterman jacket. “Fill my pussy up, brother. Please, just fill me.”

A cold fissure cracked open in your gut.

The words shouldn’t have landed like that. They shouldn’t have felt like ice water dashed over the fire in your spine. This was normal. This was what siblings did. Yet Kiersten’s desperate plea, so raw and specific, echoed in the hollow of your skull with a resonance that felt ancient and forbidden. Something deep within you, a ghost of a memory you could no longer grasp, recoiled.

It screamed that this was a violation of a fundamental law.

But then Bell hollowed her cheeks and sucked so hard your vision spotted. The slick, obscene schlorp of her lips moving on your shaft drowned out the distant voice. Pleasure, thick and electric, reclaimed every nerve ending. Your head thumped back against the locker. “Fuck, Bell,” you breathed, the curse shuddering out of you.

“See?” she mumbled around your girth, pulling off with a loud, messy pop. A string of saliva connected her swollen lower lip to your tip. Her eyes glinted with possessive delight. “They get it. No fuss, no hiding. Just taking what they need.” Her tongue swirled over your head, collecting the bead of pre-cum that had welled there. “You need to quit thinking so much.”

She swallowed you down again, deeper this time, until her nose pressed into your pubic hair. You could feel the tight constriction of her throat.

From down the hall, the rhythmic banging of metal intensified, a staccato counterpoint to Bell’s suction. A door opened somewhere, and two students walked out. They glanced toward the noise, toward Colton and his sister, then toward you and Bell on your knees. Their faces showed no shock, no disapproval. One of them, a guy you recognized from your statistics class, gave a casual nod as they passed, as if acknowledging you mowing the lawn.

The normalcy of it was the most horrifying thing of all.

Your hips began to move of their own accord, a shallow, helpless rocking into the velvet heat of your sister’s mouth. The protesting voice in your head was smothered under a dense, welcoming fog. Her hand tugged at your balls, a firm, encouraging pressure that made your toes curl in your shoes.

“Gonna come?” Bell slurred, pulling back to breathe. Her lips were slick and crimson. “Do it. I want to taste it.”

The permission, so crudely given, tightened the coil in your abdomen. You looked over her head. Kiersten was shuddering, her cries sharp and rhythmic as Colton hammered into her, his face buried in her neck. You heard his answering grunt, a raw, animal sound of release.

It pushed you over the edge.

A hot, blinding wave crested and broke. You shoved yourself deeper into Bell’s mouth as the first pulse racked you. A guttural sound tore from your throat, part ecstasy, part despair. She took it all, her throat working as she swallowed, a low, satisfied hum vibrating against your sensitized flesh. She didn’t spill a drop.

When you were spent, trembling, she released you with a final, gentle kiss. She wiped her mouth with the back of her hand, a smug, victorious look on her face. Down the hall, Colton was pulling up his pants, Kiersten sliding down the lockers to lean, dazed and smiling, against them.

Bell stood up, her knees cracking. She grabbed her notebook from the windowsill, tucking it under her arm. She looked at you, your pants still open, exposed in the bright, public hallway.

“Better?” she asked, her voice casual. Almost bored.

You could only nod, zipping yourself up with fumbling hands. The world had snapped back into a focus that felt meticulously engineered. The wrongness was still there, but it was buried now under a thick layer of sticky, compliant satisfaction.
