Trial Run Continues

Amanda's anticipation was palpable, her breaths coming in short gasps as she lay on the edge of the bed, legs spread wide. John stood by, observing the scene with mixed emotions - pride in his creation, along with a strong undercurrent of jealousy that gnawed at him.

ST9000 stood between Amanda's legs, its upgraded form imposing and muscular - a handsome facsimile of its creator. The robot's fingers gently grazed her inner thighs, causing Amanda to shiver involuntarily. John couldn't help but notice the delicate curve of her hips, the way her toned stomach quivered in response to the gentle touch. She had truly blossomed since working out with ST9000.

The robot's hand moved to cradle its newly upgraded phallus - an impressively lifelike and generously proportioned replica. Even as he felt a stab of envy, John marveled at the craftsmanship that had gone into this latest enhancement. It was nothing short of a work of art.

With great care and precision, ST9000 guided itself to Amanda's entrance, teasing her labia apart with the tip of its silicone member. Her arousal was evident in the glistening moisture that coated her most intimate area.

A small gasp escaped from Amanda's lips as the robot moved up to rub its head against her clit. The sensation sent shivers through her body, causing her nipples to stiffen and goosebumps to rise on her skin. John watched as she closed her eyes and let out a soft moan, her hands gripping the sheets beneath her.

John's jealousy twisted into an unfamiliar mix of arousal and unease as he continued to watch the intimate exchange. He was fully aware that the robot was an inanimate object, but seeing it interact so intimately with his wife made him feel like a voyeur spying on a forbidden tryst.

As Amanda's hips began to gyrate in anticipation, John felt a pang of longing mixed with possessiveness. He fought against these feelings but couldn't tear his gaze away from his wife's reactions or stop himself from noticing every detail - from the flush of desire on her cheeks to the way her chest heaved with each labored breath.

The moment stretched on as ST9000 slowly began to push its head inside Amanda's wet and willing entrance. The smooth silicone slid past her folds, stretching her open ever so gradually. John observed every inch of progress, his heart pounding in his chest.

Amanda's breath hitched as she felt the fullness of the robot's cock beginning to fill her. Her hands moved from the sheets to grip the edge of the bed, knuckles white with tension. She bit her bottom lip, trying to stifle a moan as ST9000 continued its slow, deliberate invasion of her body.

John couldn't help but be entranced by the sight before him - his beautiful wife writhing in ecstasy at the hands of his creation. The conflicting emotions within him battled for dominance - pride in the pleasure he had brought her versus a burning jealousy that threatened to consume him.

The robot's piston-like movements inside Amanda began to pick up speed, each thrust more precise and powerful than the last. It seemed to know exactly how to angle itself, driving deep into her with unwavering accuracy. John couldn't tear his eyes away from the erotic scene unfolding before him, his own arousal growing as he watched his wife's ecstasy.

As the robot's rhythmic thrusts picked up speed, John couldn't help but stare. The sight of Amanda, her body glistening with sweat and her eyes filled with pleasure, was intoxicating. It was a scene he had never witnessed before - his wife, the woman he loved more than anything else in the world, in the throes of passion with a machine that was his own creation.

"God, Amanda… you look so sexy like this," John murmured, almost involuntarily. The words hung in the air for a moment before Amanda allowed herself a sly smile.

Amanda's cheeks flushed a darker shade, but she didn't look away from the robot's face. Instead, she panted out a command. "Show me off to John."

The robot obeyed without hesitation. It slowed its movements and pulled out of Amanda, giving John a tantalizing glimpse of her slick folds before it lifted her effortlessly into its arms. Holding her securely against its chest, the robot positioned itself so that John had an unobstructed view of their joining.

John found himself with a front-row seat to the astonishing sight of his wife impaled on the robot's massive cock. He could see every detail - the way Amanda's juices glistened on its shaft as it slid in and out of her; the subtle curve of her hips as they met its thrusts; even the slightly **** expression on her face as she surrendered herself completely to the pleasure it was giving her.

It drove its cock back into Amanda with deliberate slowness. John couldn't tear his eyes away as inch by inch, the thick length disappeared inside her. He marveled at how she accommodated it; her inner muscles gripping and releasing in time with its movements.

Amanda's petite frame quivered under the **** of each thrust. Her breasts jiggled enticingly as they bounced against the robot's chest - nipples hard and flushed a deep pink from arousal. Her toned legs were wrapped around its waist, clinging tight as though she feared being swept away on this tidal wave of pleasure.

John could see everything - every tremor that passed through his wife's body; every drop of sweat that trickled down her toned stomach; every gasp and moan that escaped her lips. And right there before him were the lifelike balls of the robot, now slapping against her clit with each powerful thrust. The sensation seemed to drive her wild, and she threw her head back, a guttural moan escaping her throat.

This new addition only served to heighten John's arousal further. He couldn't help but be entranced by the sight and sound of those large balls hitting his wife's sensitive bud with each powerful stroke. It was almost as if the machine was showing off its newfound virility, daring him to compare himself to it.

The robot continued to pound into Amanda, the **** of its thrusts causing its large balls to swing and slap against her sensitive bud. The sound of skin on skin filled the room and mingled with Amanda's cries of pleasure.

John found himself entranced by the sight: The girth of the robot's cock stretched Amanda's pussy lips wide around it, making them cling tightly to its shaft each time it pulled back. Drops of her arousal glistened on its artificial skin as it plunged in and out of her slick heat.

And then, as if that wasn't enough, John noticed something else - the outline of the robot's cock pushing against Amanda's toned stomach from the inside as it filled her completely. He could see the shape of its girth stretching her in a way he never had, causing her body to quiver and shake with each thrust. And as he watched that outline, he realized that his wife was nearing her climax.

Amanda's breaths came in short, ragged gasps now, her body tensed and twitching with every movement of the machine inside her. Her eyes locked onto John's, their depths filled with a mixture of lust and adoration that sent shivers down his spine. He knew she was close - so very close - and he wanted nothing more than to see her reach that peak.

And then Amanda came.

Her body went rigid in the robot's arms as pleasure ripped through her. Her eyes rolled back in her head, and a strangled cry tore from her throat. For a moment, John could see every muscle in her body tense and shudder under the **** of her climax.

Then, just as suddenly as it had happened, it was over. Amanda slumped against the robot, panting heavily and blinking stars from her eyes. Her flushed cheeks glistened with sweat, and a satisfied smile on her adorable face.

John had never seen anything so beautiful in his life.

As John watched his wife experience such intense pleasure at the hands of his creation, he couldn't help but feel both jealousy and arousal surge through him. He had given life to this machine - this perfect lover - and yet it was Amanda who reaped the benefits of its existence.

Even as these thoughts swirled through his mind, he couldn't deny one simple fact: watching Amanda in this moment was undeniably intoxicating.
