Identical Sins

A Seductive Saturday Short

Jaxon had been rushing home since his flight landed early. Two weeks away from Isla had left him restless, hungry in ways that had nothing to do with food. He wanted to surprise her, to walk in and catch that soft, startled smile she always gave him before melting into his arms. She would be awake now, probably making coffee, and her sister would still be asleep from a late night out. They would have a little bit of privacy.

He bit his lip as he turned the key slowly in the lock, easing the apartment door open just wide enough to slip inside, then guided it shut again with the barest click, muffling the sound against his palm.

The hallway was dim, soft morning light slanting through half-closed blinds. He set his duffel down gently and breathed in the familiar scent of coffee. His pulse raced as he crept in, careful not to make any noise. He couldn’t wait to slip inside her, make her moan softly. Two weeks. He was already half-hard thinking about it.

He snuck quietly toward the kitchen, drawn by the soft clink of a spoon against ceramic.

There she was, just as he imagined. Her back was to him, her long dark hair spilling down her shoulders. She was wearing a body-hugging tank and shorts that barely covered her beautiful ass.

He closed the distance in silence, arms sliding around her waist from behind, lips brushing the warm curve of her neck. “Hey, beautiful,” he murmured, voice rough with travel and want.

She stiffened for the briefest second, then relaxed into him with a low, pleased hum that vibrated against his chest. “You’re home early,” she said, tilting her head to give him more skin.

“Couldn’t stand another night without you.” His hands wandered, slipping under the soft hem of her tank, fingers splaying across the smooth warmth of her stomach. She arched back against him, pressing her ass into his growing erection with deliberate pressure. The move was bolder than usual, more demanding.

She must have really missed me, too, he thought, pressing his aching cock against her.

“I think you’re happy to see me,” she whispered, voice husky, playful, as she pressed her ass harder against him. She turned in his hold, lips finding his in a kiss that started soft and turned feral quickly. He groaned into her mouth, lifting her onto the counter in one smooth motion. Her legs hooked around his hips instantly, pulling him flush.

Something flickered at the edge of his mind. She’s never this bold. Her nails raked down his back instead of tracing gentle circles. She seemed different.

Before he could think about it any further, she slipped her hand over his erection, her fingers greedily running over the fabric of his jeans. His mind went blank. He thought he might explode before they ever started. He kissed her harder, his hands shoving her tank up to palm her plump breasts.

“Bedroom,” she breathed against his lips. “Now.”

He carried her down the hall without breaking the kiss, her fingers already yanking his shirt over his head. They stumbled into the bedroom, mouths fused, hands frantic. He spun her around, bending her over the edge of the mattress so her palms braced on the sheets, ass presented high. He shoved his jeans down just below the curve of his ass, just enough to free his cock, and then tugged her shorts and panties to the side in one pull.

He entered her slowly, carefully, savoring the tight, slick heat that enveloped him. He moved his hips in gentle, measured rolls, just how he knew Isla liked it. She sighed softly at first as she took him in, her pussy gripping him tightly.

Suddenly, Aria rocked back hard, slamming her hips against his to take him deeper, faster. A low, throaty moan spilled from her lips, then another, louder, shameless. “More!” she gasped, pushing back insistently with every stroke. “Fuck, Jaxon, give it to me!”

That funny feeling in his brain, the one he’d tried to ignore, came roaring back. Her moans were raw and unfiltered. The pleas that were spilling from her lips were filthy. Her pussy clenched around him, greedy and insistent, milking every inch like she couldn’t get enough. Maybe she just really missed me, he thought, desperately trying to rationalize the situation.

Isla was quiet and familiar in bed. She would occasionally let out soft sighs, and she preferred gentle rocking to anything remotely rough. She was happy to let him lead while she lay beneath him like a pillow princess. She never chased. Never demanded. Never flooded the room with those desperate, animal sounds that was making his blood pound and his control fray. He often had to fantasize while they were having sex to keep himself aroused. Maybe it’s just been so long that she’s hornier than usual. Maybe she’s trying something new?

This…this was being devoured.

His heart pounded as a thought suddenly occurred to him. Isla had that tiny heart-shaped freckle on her lower back, right at the dip of her spine, the one he loved to trace with his thumb when he took her from behind. He frantically searched for it now, eyes narrowing.

Nothing.

The realization slammed into him like ice water.

He froze, still buried deep, breath sawing in and out.

“Aria?” he said, the name rough and low as it spilled from his lips.

She glanced back over her shoulder, lips curved in slow, wicked triumph. “Hi, handsome.”

Shock roared through him, betrayal, fury, confusion, but hotter than any of it was the truth staring him in the face: she’d let him think she was Isla. She’d taken everything he’d meant for her sister. And fuck, he’d never felt this desired in his life. No hesitation, no restraint, just pure, animalistic want.

His balls drew up tight, pleasure spiking so sharp and sudden in his gut he nearly lost it right there. He’d never been this close to blowing his load this fast. His hands tightened on her hips until his fingers would leave marks.

He didn’t pull out.

His mind and body were torn between wanting to feel shame and regret, knowing what he was doing was so wrong…but it felt so good, so right. He knew had a decision to make, and he didn’t have long. He was getting dangerously close to filling this new pussy up, and he knew he was going to come hard.

Desperate to feel release, he knew he couldn’t stop. Scratch that, he didn’t want to stop.

Fuck it. He knew he would have to deal with the consequences, but at this moment, those consequences seemed worth it.

He pulled back almost all the way, and then slammed forward, hard and deep. Aria cried out in pleasure, loud and unfiltered, the sound echoing off the walls, as though she didn’t care who heard, neighbors be damned. He set a punishing rhythm now, brutal, relentless thrusts that made her body jolt forward with every snap of his hips. She pushed back to meet him eagerly, moaning his name, filthy pleas tumbling from her lips: “Yes! fuhhhh..harder, Jaxon!”

They were completely lost in it. Their sweat-slick skin slapped loudly, Aria’s cries growing wilder as Jaxon slammed into her. He groaned loudly as he watched his cock slip in and out of her wet pussy.

-----

Isla opened the door to the apartment and stepped inside, gym bag in hand, still flushed and sweaty from her workout. She expected silence. Aria always slept in after passing out from a wild night on the town.

Instead, she heard rhythmic sounds like a bed squeaking and skin slapping skin. She could hear hungry-sounding grunts. High, desperate feminine moans. The neighbors were getting wild early this morning!

She walked toward her bedroom, and the noises grew louder. The woman’s voice sounded eerily familiar.

Her stomach plummeted. No…it couldn’t be. He’s not supposed to be home until tomorrow.

She set her bag down without a sound and crept down the hall on shaking legs. The bedroom door stood slightly ajar. She pushed it open just enough to see.

Jaxon had Aria bent over the bed, jeans shoved down, hips driving forward with unrestrained force.

Aria’s face was flushed, mouth open in wrecked pleasure. Jaxon looked completely undone. His eyes were dark, and his jaw was clenched, sweat beading on his brow as he fucked her like he couldn’t get deep enough.

Hot and blinding fury exploded in Isla’s chest. Her boyfriend. Her twin. In their bed.

She was speechless as she tried to process the scene before her, her heart racing.

She watched.

What she saw was raw intensity. Jaxon’s hands gripped Aria’s hips like he was afraid she’d disappear if he let go. Aria arched back, chasing every thrust with shameless need. This was in stark contrast to their own careful, measured sex. Isla had always preferred gentle. Safe. Quiet. Jaxon had respected that, kept things tender.

This was the opposite. Primal. Consuming.

Her rage started to subside as heat bloomed low in her belly, unexpected and sharp. Her breath quickened. Her thighs pressed together instinctively, her pulse thudding between her legs. She gasped in surprise at her body’s reaction to the scene before her.

Aria’s eyes flicked up, locking on Isla’s in the doorway. A slow, knowing smile spread across her flushed face even as another moan tore from her throat.

Jaxon, not hearing the gasp, noticed Aria’s attention being diverted. His gaze snapped to the door.

Isla was standing in the doorway. She stood frozen in her tight gym leggings and cropped top, skin still glistening with sweat, chest heaving, a storm raging inside her. He quickly pulled out of Aria, with no idea what to do. He wanted to run away. He wanted to finish. Instead, he took a step toward Isla.

He expected fury. Screaming. Tears. Maybe her storming out and slamming the door so hard the neighbors would call the cops.

Instead, Isla didn’t move. Her lips parted on a soft, shaky exhale. Her gaze dropped to where his cock, still rigid, slick, and flushed, jutted from his open jeans, then flicked back to Aria’s flushed, satisfied face.

Jaxon followed her line of sight. Heat crawled up his neck. He tried to cover himself, hands fumbling, but the attempt was pathetic. His palms barely concealed the thick, veined length, the head still glistening with Aria’s arousal. The more he shifted, the more obvious it became.

“Aria, I can’t believe you,” Isla finally managed, voice low and trembling.

Aria opened her mouth, ready with some smart retort, but Isla cut her off.

“And Jaxon… what the hell?” Her brows knit together, hurt flashing raw in her eyes. “You never fuck me like that.”

Jaxon’s throat worked. He rasped, “But…you told me you don’t like it like this.” His hands still hovered uselessly over his erection, trying and failing to hide how hard he remained. “You’ve always said go slow. Be gentle.”

Why the fuck won’t it go down? his mind screamed. Aria had been so wet, so greedy, that he was soaked, her scent clinging to him, his cock throbbing angrily at the memory. He finally clasped one hand over the other, pressing his length flush against his stomach in a vain attempt at modesty. It only made the pulse more obvious.

Isla’s breath hitched. The words stung because they were true, and because saying them aloud made the ache between her thighs sharpen into something insistent, almost painful.

She took one step forward. Then another. Her gym shoes were silent on the carpet. Her eyes dropped again to his poorly hidden cock, watching it twitch under his palms.

She reached up and brushed his sweat-damp shoulder with tentative fingertips, light at first, then firmer, like she was trying to convince herself.

“I think…” Her voice cracked, small and unsure. “I-I think I want to try it now.”

Jaxon’s pupils blew wide. His cock jerked hard beneath his hands, a fresh bead of pre-cum welling at the tip and smearing against his palm.

Aria looked at her twin in genuine surprise, then broke into a slow, wicked smile. “Hell yeah,” she purred, voice still husky from her own orgasm. “You’ve got a lot to learn, sis. Lucky for you, class is in session. Get those fucking clothes off.”

Isla didn’t argue. She grabbed the hem of her cropped workout top and peeled it over her head in one swift motion. Her breasts spilled free, her nipples already peaked, dark and tight from the cool air and the fire licking through her core. She kicked off her sneakers, shoved leggings and panties down together, the damp fabric clinging briefly to her thighs before she stepped free. Naked now, skin flushed pink from exertion and arousal, she climbed onto the bed.

Jaxon let his hands fall away. No more hiding. His cock stood proud again, rigid, veined, the shaft still glossy from Aria’s pussy, the head flushed an angry plum color. He sat back against the headboard, legs spread wide, chest rising and falling in heavy rhythm.

“C’mere,” he said to Isla, voice gravel-rough and edged with command. “You want different? You’ll get different.”

Isla crawled toward him on hands and knees, heart hammering. When she was close enough, Jaxon cradled the back of her head, his fingers threading into her damp hair, gentle but firm.

“First,” he said roughly, eyes locked on hers, dark and needy, “I want you to suck your sister off of me.”

Isla’s eyes widened. Her lips parted on a soft, shocked exhale. She started to shake her head. It was her instinct to protest, but Jaxon guided her down slowly, inexorably, until the slick tip brushed her lower lip.

The scent hit her first: musky, salty, unmistaken. It was thick and feminine, mixed with the sharper tang of Jaxon’s arousal. She hesitated, breath fanning hot over his cock. Then she opened her mouth.

Her tongue darted out, tentative, exploratory, lapping at the underside of the head. The taste exploded across her tongue: Aria’s sweetness, Jaxon’s salt, the slippery evidence of what they’d done without her. A soft whimper escaped her throat. She closed her lips around the tip, sucking gently, tongue swirling to collect every trace.

Jaxon groaned low, fingers tightening in her hair. “That’s it…clean her off me. Taste how wet she got for me.”

Isla moaned around him, the vibration humming down his shaft. She took more, sliding down inch by inch until her lips met the base, nose brushing his pubic bone. She hollowed her cheeks, sucking harder, tongue working the underside in slow, deliberate strokes.

Aria watched with heavy-lidded eyes, one hand idly circling her own clit. “Fuck, look at her go. Didn’t know you had it in you, sis.”

Isla pulled off with a wet pop, cheeks flushed, lips shiny. She looked up at Jaxon, her eyes glassy, pupils blown.

He stroked her cheek with his thumb. “Good girl. Now turn around and sit on me.”

Aria moved behind her, hands on Isla’s hips, guiding her to straddle Jaxon reverse-cowgirl. Isla’s knees sank into the mattress on either side of his thighs. She felt obscenely exposed, her ass presented to Jaxon, her pussy glistening with her legs spread wide open, wetter than she’d ever been before.

Aria pressed against Isla’s back, breasts soft and warm against her spine, mouth at her ear.

“Lean forward. Hands on his thighs. Arch that back. Yes, just like that. Let him see how dripping wet you are.”

Isla obeyed. Palms braced on Jaxon’s legs, she arched, offering herself. Jaxon’s hands slid up her thighs, thumbs spreading her open. The broad head of his cock nudged her entrance. It was hot, extremely hard, and still slick from her mouth.

“Slow,” Aria murmured, fingers slipping between Isla’s legs to circle her clit with light, teasing pressure. “Take what you can…then take more.”

Isla sank down.

The stretch burned sweetly. He felt thicker at this angle, pressing against every sensitive wall. She gasped, body fluttering around the first few inches. Jaxon groaned beneath her, hands clamping her hips to keep from thrusting up too soon.

“Fuck, Isla…” His voice cracked. “You’re so tight like this.”

Aria’s fingers never stopped. She was rubbing tight, steady circles over her clit while Isla lowered herself further, inch by inch. Her ass finally met his hips and he was fully inserted, his thick head kissing her cervix.

Isla gasped and whimpered, her thighs quivering. The fullness was overwhelming. He felt much deeper than their careful missionary ever reached.

Jaxon cupped her breasts from behind, thumbs flicking her nipples. “Move. Ride me. Show me you want it rough.”

Isla lifted slowly, then dropped. The slap of her ass against his thighs rang out. She did it again, faster. Each descent dragged him over that perfect spot; sparks shot behind her eyes. Her moans grew louder, breathier, unrestrained. She had always been too shy to make much noise. She had always held back. Hearing Aria earlier made her realize how silly that was.

Jaxon pulled her so that she leaned back against him, grasping her hips to move her more roughly on his cock.

Seeing her opportunity to join, Aria slid down between Jaxon’s spread legs, lying on her belly so that her face was level with their joining.

Isla felt so exposed, her pussy getting fucked mere centimeters from her sister’s face. She had no idea what was happening.

Then Aria’s tongue found her clit, and electric shocks ran throughout her body. She let out a gasping moan as Aria lapped at her clit, and then moved down. She tasted Isla’s creamy arousal, slipping her tongue across Jaxon’s stiff cock and Isla’s stretched entrance. They both moaned at the sensation.

After a few moments, Aria swirled up to suck Isla’s swollen bud between her lips. She flicked it back and forth with her tongue and then sucked gently. Isla cried out, hips jerking, fucking herself down onto Jaxon with desperate snaps.

“Yes…fuck! Don’t stop!” Isla’s voice broke into sobs of pleasure.

Jaxon thrust up to meet her now using short, powerful bucks that slapped wetly against her ass. The sounds were obscene: her pussy sucking greedily at him, Aria’s tongue slurping against her clit, flesh slapping flesh.

Isla shattered first, her orgasm crashing through her like a dam breaking. Her walls clamped down hard around Jaxon, pulsing, milking. She sobbed his name, thighs shaking violently.

Aria kept licking through it, drawing out her pleasure, until Isla was whimpering, oversensitive.

Jaxon followed seconds later. “Isla…fuck, I’m gonna come!” He slammed up once more, burying deep, and came with a guttural groan.

Hot, thick ropes flooded her in spurts. Aria felt Jaxon’s cock thumping with each spurt as he filled Isla’s pussy. Cum spilled out around his shaft, and Aria’s tongue chased every leaking drop.

Isla collapsed against him, panting, her pussy swollen and slick with cum. Aria lapped at them. She could feel both them throbbing as the waves passed over them.

Once she was satisfied that she had licked them clean, Aria pulled back. Her lips were shiny and her eyes gleamed with satisfaction. She crawled up and kissed Isla deeply, sharing the mingled taste. She then leaned over to share with Jaxon, who moaned as he tasted the mixture. Aria then bent down and gently took one of Isla’s nipples in her mouth, suckling and tugging at it with her lips.

Isla, still sitting on Jaxon’s cock, could feel electrical shocks shooting straight from her nipple to her pussy with each tug, extending her pussy’s pleasure.

When Aria finally stopped, Isla managed a shaky whisper. “I…I think I like different.”

Aria grinned. “Told you. Class dismissed…for now.”

Isla slowly lifted off Jaxon and took her place beside him, lifting her chin to kiss him. This kiss was softer, almost reverent, but still edged with the aftershocks of what they’d just done.

Aria flopped down on his other side, grinning. “Told you you had a lot to learn.”

Isla managed a shaky laugh, feeling the slow leak dripping out of her. “I’m…I’m a quick study.”

Jaxon wrapped his arms around her, pulling her close. “Good,” he murmured against her neck. “Because I see a lot of lessons in our future.”
