Trent lay on his bed, staring at the ceiling fan, listening to its hypnotic whirring. His eyes felt heavy, but sleep remained elusive. Thoughts of his sister's luscious breasts swirled in his mind. He had always admired them from afar, his imagination a wildfire of desire, burning with an incestuous craving that society deemed taboo.

Her name was Sam, a name that seemed too simple, too plain for the beauty she embodied. Sam had always been the center of his world—his confidante, his protector, and, in his darkest thoughts, his obsession. Her laughter was like the sweetest melody, her scent intoxicating, and her touch... forbidden.

Tonight was different. The house was quiet, their parents out at a party. His heart hammered in his chest as he tiptoed to her room, the carpet muffling his footsteps. The door was a silent sentry, guarding the secrets within. With trembling hands, he pushed it open, revealing her silhouette, illuminated by the moon's soft glow. She lay there, her chest rising and falling with the rhythm of sleep. The sight of her made his mouth go dry, his body rigid with anticipation.

Her breasts were like twin peaks beneath the thin fabric of her nightgown. He approached her bed, the heat from his body casting a shiver down her spine. Sam stirred slightly but didn't wake. He could see the outline of her erect nipples, begging for attention. His hands hovered, mere inches from her flesh, before finally making contact. They were softer than he had ever dared to imagine—like pillows filled with pure ecstasy. He couldn't resist the urge to cup them gently, feeling their weight in his palms, his thumbs tracing delicate circles around the sensitive tips.

Her breathing hitched, and her body tensed, but she remained asleep. Emboldened, he leaned down, his hot breath whispering across her neck as he took one nipple into his mouth through the thin fabric of her nightie. He sucked softly at first, then harder, feeling it swell against his tongue. A soft moan escaped her lips, and his cock throbbed in response. He knew he had crossed a line, but the thrill of it only spurred him on.

He reached down and slid the strap of her nightgown down her shoulder, exposing one of her breasts to the cool air. The sight was more than he could bear. He had to have her, fully, completely. With one swift movement, he pulled her gown down, exposing her breasts fully. The moonlight painted them in a heavenly glow, making them seem almost otherworldly. He couldn’t believe he was touching them, that they were real and in his grasp.

But suddenly, a creak from the hallway sent a bolt of panic through his veins. He froze, his heart hammering like a jackhammer in his chest. One of his parents was definitely moving around out there. He had to get out before he was caught. He reluctantly pulled away from Sam, his eyes never leaving her chest. The feel of her flesh was etched into his mind.

With a silent curse, Trent retreated from her bedside, his eyes darting to the doorway.

He slipped back into the shadows, his heart racing as the sound grew louder. He managed to pull her nightgown back into place before darting out of the room, closing the door with the stealth of a cat burglar. He rushed back to his own room, his breath coming in ragged gasps. The adrenaline mixed with his lust made his head spin as he collapsed onto his bed. The image of his sister's breasts was seared into his retina, and his cock was painfully erect.

He couldn't let the moment go to waste. His hand found its way into his boxers, wrapping around his hot, throbbing cock. He began to stroke himself, his mind playing back every detail of her exposed flesh. The way her nipples had pebbled under his touch, the softness of her skin, and the sweet scent of her that had filled the room. His strokes grew quicker, more erratic as he thought about what had almost happened. The danger of being caught had only made his desire more intense.

With each pump of his fist, he imagined it was her hand on him, her mouth around his shaft, her breasts crushed against his chest. He bit his lip to stifle the moan that bubbled up from his throat as he grew closer to climax. The tension in his body built until it was unbearable. He could almost feel her touch again, her soft skin against his own. His hand was slick with precum as he brought himself to the edge.

In the quiet of his room, the sound of his breathing was like a symphony of lust. He closed his eyes tightly, picturing Sam’s face, the way her eyes would widen in shock and arousal if she knew what he was doing right now. He stroked faster, his mind racing with the thoughts of what would happen if she ever found out. Would she be repulsed? Or would she succumb to the same dark desires he felt?

His grip tightened around his cock. He could feel the orgasm building, his balls tightening with the sweet promise of release. Then the image of Sam’s eyes fluttering open, a look of surprise and... pleasure?... flashed through his mind. She’d whisper his name, arching her back and pushing her chest towards him, inviting him to take more, to take everything. It was this fantasy that finally sent him over the edge.

The next morning, the house was bathed in the warm glow of early sunlight. Trent lay in bed, his mind racing with what had transpired the night before. The weight of his secret was like a boulder on his chest. He could still feel the phantom sensation of Sam’s breasts in his palms.

Finally, he dragged himself to the kitchen, his body feeling both exhausted and electrified from the night before. He poured himself a bowl of cereal, the crunch of the flakes against the spoon echoing in the silent room. As he sat at the table, trying to distract himself with the mundane task of eating, he heard the pitter-patter of Sam’s footsteps on the stairs. His heart skipped a beat.

In she came, a vision of unknowing temptation. She was wearing shorts so tiny they barely contained the cheeks of her ass and a tank top that clung to her like a second skin. Her breasts, his sister’s breasts, bounced gently with each step she took, a silent siren’s call that he couldn’t ignore. He tried to keep his gaze on the breakfast cereal, but his eyes kept darting up, tracing the curves that had been the star of his fantasies for so long.

They were full and heavy, like ripe melons. The way they swayed with her movements made blood rush to his cock. Her nipples, now hidden under the thin fabric of her shirt, were a dark secret, yearning to be set free. The memory of them, pink and erect, was etched in his brain. He could almost feel them again, the way they had felt under his tongue, the way they had hardened at his touch.

Trent’s cock grew harder with every second that passed, straining against his boxers. He could feel the heat radiating from it, a constant reminder of his insatiable hunger for her. The fabric of his shorts stretched tight over his growing arousal, creating a tantalizing outline that made it impossible to ignore. He shifted in his chair, trying to find a comfortable position, but it only made his erection more pronounced.

Sam, oblivious to his struggle, hummed a soft melody to herself as she moved around the kitchen. She was always so carefree in the mornings, her voice a gentle lullaby that soothed the ragged edges of his desire. She reached up on her tiptoes, her body elongating like a dancer’s, to grab a glass from the upper cupboard. The way her shorts hugged her ass, riding up to reveal the pale, unblemished skin of her thighs was mesmerizing. He watched, his eyes glued to the spot where the fabric met her flesh, as the muscles in her legs flexed and relaxed. The sight of her ass cheeks peeking out, just barely covered, was enough to make him want to drop the spoon and take her right there on the kitchen counter.

He couldn’t help but wonder how she would react if he were to lift her up, placing her on the cool surface of the countertop, and bury his face in her chest. Would she push him away in horror or moan in surprise as he suckled her tits, his mouth greedily devouring the flesh that had fueled his fantasies for so long? The thought sent a jolt of electricity down his spine.

Then, as if the universe had heard his thoughts, she turned around. The way her shorts clung to her, creating a camel toe that was impossible to ignore, made him swallow hard. God what he wouldn't do to be that thin fabric nestled between her pink pussy lips. His hand tightened around his spoon, his knuckles turning white.

But before he could indulge in his fantasy further, their father’s stern voice boomed through the kitchen. "Samantha, what do you think you're doing? You can't go out dressed like that!" Dad's heavy footsteps grew closer, his disapproval palpable in the air.

"What's wrong with what I'm wearing?" Sam shot back. "I'm going to the beach, Daddy."

Trent felt a smirk tug at the corner of his mouth. Dad's over-protectiveness was as predictable as the sunrise. He knew his father was just trying to keep his little girl covered up, but the sight of Sam dressed so provocatively only served to fuel Trent's darker cravings.

"Young lady, you're not leaving the house dressed like that," their father said, his voice a thunderclap in the quiet room. "Go put on something more appropriate."

Sam rolled her eyes, the defiance in her posture clear. She stomped up the stairs, her ass jiggling with each step. Trent couldn't help but watch, his mouth watering at the sight. He knew he should feel guilty for his thoughts, but the desire was too intense, too overpowering. He could almost feel the firmness of her buttocks beneath his palms, the way they'd bounce and quiver as he fucked her from behind.

"Trent, hurry up with your cereal," his father's voice boomed again, breaking the spell. "We've got work to do in the garage."

Trent's cock deflated slightly, his mind reluctantly shifting from the tantalizing vision of his sister to the mundane reality of the day ahead. He quickly gulped down the last of his milk and followed his father out to the garage, the smell of oil and dust immediately assaulting his senses. The garage was a mess, a graveyard of forgotten projects and tools scattered about haphazardly.

They spent the next few hours cleaning, their hands and clothes soon covered in a fine layer of grime. The physical labor was a welcome distraction from his carnally charged thoughts, allowing him to focus on the task at hand. The rhythmic motion of his arm as he swept the floor was almost meditative, pushing the images of Sam's body out of his mind—or at least to the back of it.

But as the day grew later, and the shadows began to stretch across the lawn, Trent couldn't ignore the anticipation building within him. He knew she'd be home soon, and he could already feel his restraint slipping.

That night, as the stars winked into existence and the house grew still, he heard the soft click of the front door and the whisper of her footsteps as she padded down the hallway. His heart hammered in his chest. Sam had returned from her beach trip, her skin surely kissed by the sun and her hair a salty mess from the ocean.

He waited, his breath shallow and his eyes glued to the crack under her bedroom door. The sound of the shower being turned on was like a siren’s call to him. He couldn’t resist. He had to see her, had to feel close to her in some way.

He crept down the hallway, his feet making no sound on the plush carpet. His heart hammered in his chest like a wild animal in a cage. The door to her bathroom was slightly ajar, the steam from the shower curling into the hall like a beckoning hand. He approached it, his eyes greedily drinking in the sight of the water droplets racing down the tiles, the mirror fogged with condensation.

Through the crack, he could see the outline of Sam’s body, obscured by the frosted glass door. The sound of the shower was a symphony to his ears—the spray of water, the soft patter of droplets on skin, the occasional squeak of wet flesh against the shower wall. The anticipation was unbearable, a coil of tension in his belly that grew tighter with each passing second. He had to see her.

Trent inched closer, his hand reaching out to touch the cool metal of the door handle. The thought of being caught sent a thrill up his spine, but he didn’t care. His sister’s breasts were his, and he would watch them whenever he liked. He pushed the door open, the steam enveloping him like a warm, wet blanket. She didn’t hear him at first, lost in the rhythm of her shower, her hands gliding over her soapy skin.

The sight of her made him ache. Her naked body was a masterpiece—curves in all the right places, her breasts full and heavy, the water cascading down her body like a river of temptation. He could see the faint outline of her nipples through the frosty glass, begging for his touch. The desire to join her, to feel her wet, slippery skin against his, was almost overwhelming. But he knew he couldn’t. Not yet.

Sam's hand traveled down her torso, gliding over her belly and hips. She had the body of a goddess, and he was the mortal, forbidden to touch. She stepped closer to the door, the water rushing over her skin, and his eyes followed her hand as it moved lower. She began to wash her legs, her fingers tracing the length of her thighs. His breath caught in his throat as he imagined those same fingers wrapped around his cock, stroking him with the same gentle precision.

Her hand reached between her legs, and he watched, entranced, as she began to soap up her pussy. The glass was foggy, but he could see enough to make out the pink flesh, the way her fingers moved in a circular motion. He wondered if she was thinking of him, if she knew how much he craved her. His own hand found its way into his shorts, his cock already stiff and eager.

Her breath grew heavier, her moans soft but unmistakable. The sound pulling him closer, urging him to give in to his desires. He leaned against the wall, his heart racing as he watched her hand move faster and faster. Her breasts swayed with the rhythm of her masturbation, the water running down her body in rivulets, mixing with the soap to make her skin glisten.

The moan grew louder, a keening sound that seemed to resonate through his very bones. He could see the tension in her shoulders, the way her back arched as she reached climax. Her hand moved frantically now, rubbing at her clit in a desperate bid for relief. Her hips bucked slightly, her legs trembling with the effort of staying upright. Fuck she was gorgeous.

Trent's hand was a blur in his shorts, his strokes matching hers beat for beat. He couldn’t tear his eyes away from her body, his mind racing with thoughts of what he would do to her if he were in there with her. The glass was wet with condensation, his own breath fogging it up as he watched. His hand tightened around his cock, the pressure building until he thought he might burst.
