Swap Sis “It’s so unfair that they get to get off!” S3:E9

Title: “Swap Sis: The Unfair Delights of a Family Swap”

Natalie and Nick’s parents, in a moment of liberal excess, had suggested a family swap with their friends, the Robinsons. Natalie, a demure 18-year-old brunette with long silky hair and perky breasts, was hardly convinced. She visualised their embarkation on this swap as a plunge into a delightful abyss of incestuous bliss.

On the appointed day, the Robinsons moved into their home, while Natalie found herself sharing her new room with Ethan, the eldest son. He was tall, muscular, and had a mop of dark hair. Natalie couldn’t help but steal glances at him as he moved his luggage around the room. She caught a glimpse of his chiselled abs as his shirt hitched up, causing her to bite her lip.

That night, as they lay in their bunk beds, Natalie could not sleep. Her mind raced with images of Ethan. She rolled onto her side, catching a whiff of his fresh, masculine scent lingering in the bed. In the dark, she heard him shift in his bed, and she imagined the contours of his strong body moving beneath the sheet.

Suddenly, Natalie threw back her covers and let her nightgown slip off her slender shoulders. She tiptoed softly to Ethan’s bed and whispered his name. He stirred awake, his eyes adjusting to the darkness. Natalie straddled him without a word, her pert nipples brushing against his bare chest. Ethan’s hands found her hips, his fingers digging into her soft flesh as she ground herself against his growing arousal.

Natalie’s hand roamed down his body, brushing past his navel to palm his hardening cock. She wrapped her fingers around his shaft, stroking him as he let out a quiet moan. He reached up and cupped her pert breasts, giving her nipples a firm squeeze. Natalie gasped, her hips bucking against his hand as she jerked him faster.

Ethan’s hands slid around to cup her round ass, pulling her hips closer as he thrust up against her. Natalie whimpered with need, feeling his thick cock rub deliciously against her soaked panties. She pulled her underwear aside, letting the head of his cock brush against her slick folds.

Natalie lifted her hips and slowly sank down onto Ethan’s rigid shaft. She moaned softly as he stretched and filled her tight pussy. He gripped her hips, pushing himself deeper into her wet heat. Natalie began to move, riding him slowly as their breaths grew heavier. Ethan bucked his hips, driving his cock deeper with each upward thrust.

Natalie’s moans grew louder as she rode him harder, her body connecting with his in the darkness. Ethan reached up and tugged the straps of her nightgown down, exposing her perky breasts to the cool air. He leaned forward, taking one of her nipples into his mouth. Natalie gasped, arching her back to push more of her breast into his eager mouth.

Her pussy clenched around his cock like a vice as she gripped his shoulders, riding him faster. Ethan thrust up into her with deep strokes, hitting the best spot inside her with each drive of his hips. Natalie was close, her body primed for Climax and Ethan’s own grunts and moans signalled his impending Climax.

With one last thrust, Natalie’s body went rigid, her pussy spasming as she came hard on Ethan’s cock. He followed only a moment later, shooting thick ropes of cum deep inside her as he groaned loudly. They lay tangled together as their bodies to recover, the secrets of their pleasure hidden in the darkness.

Over the coming days, Natalie and Ethan maintained their salacious activities under the pretense of being host siblings. Their covert sessions often involved hot and heavy action in the shared bathroom or stolen moments in the attic when the adults were distracted. The thrill of being discovered only heightened their lusts.

During one sensual encounter, Ethan fucked Natalie in the “missionary” position, burying his cock into her wet cunt while his mouth suckled on one of her pert, pink nipples. Natalie wrapped her long legs around his muscular back, pulling him impossibly deeper inside her. She tossed her brunette head from side to side, panting as she met his every thrust.

“Fuck me harder, Ethan,” Natalie gasped. “I need to feel every inch of your cock destroying my pussy.”

Ethan obliged, slamming his thick dick into her eager cunt with renewed vigour. Natalie threw her head back and moaned loudly, uncaring that her parents might hear. The risk of being caught only intensified their pleasures.

He reached down to rub her sensitive clit at the same time that he pistoned in and out of her sopping wet slit. Natalie’s toes curled as an intense orgasm hit her squarely. She clawed at Ethan’s back as her slick walls squeezed his thrusting shaft rhythmically. Ethan groaned, spilling his load deep inside her grasping pussy.

They lay entwined a while longer, panting in the afterglow, their bodies slick with sweat. They giggled quietly like schoolchildren sharing a joke. Natalie bit her lip, already thinking about how she could engineer the next illicit assignation.

In the end, Natalie and Ethan’s family swap had delivered far more than they could have hoped for. With hurdles like her natural shyness and Ethan’s relative lack of experience, they overcame each barrier as they embarked on a journey of unrestrained experimentation. Though they parted ways after a few weeks, they had forever formed a unique kind of bond – two youthful friends who had unlocked some of life’s greatest mysteries in each other’s embrace
