The house had always been quiet after dark, but tonight the silence carried weight. Marcus stood in the doorway of his mother's bedroom, the small black device in his hand pulsing with a low red light. Elena, 42 and still carrying the curves that had once drawn every eye in the room, sat on the edge of the bed in her silk robe. She looked up, startled.
"Marcus? What are you doing with that thing?"
He didn't answer with words. He pressed the button. The light flared, and Elena's body jerked once, then stilled. Her eyes glazed, lips parting slightly as the programming flooded her mind. The device was crude but effective, designed for exactly this: overwriting will with obedience, turning flesh into programmable pleasure.
"Stand," he ordered.
Her limbs moved without her consent, smooth and mechanical. The robe slipped from her shoulders, revealing full breasts and the soft swell of her hips. She stood naked, posture rigid, waiting for the next command.
"From now on you are my sex robot," Marcus said, voice low and steady. "You will respond only to my voice. Your body exists for my use. No resistance. No refusal."
Elenas mouth formed the words he had programmed into the device earlier. "Yes, Master. I am your sex robot."
The power exchange settled over the room like heat. Marcus circled her, running his hand down her spine. Her skin was warm, but her expression remained blank, eyes unfocused. He cupped one breast, thumb circling the nipple until it hardened under mechanical obedience. A soft, recorded moan escaped her lipsthe device supplying the appropriate sound.

"On your knees."
She dropped instantly, the motion precise, almost graceful. Her hands moved to his belt without hesitation, freeing him. When she took him into her mouth, the sensation was wet and perfect, her tongue working in programmed rhythm. Marcus watched her head bob, the former mother reduced to a vessel of programmed service. He gripped her hair, controlling the depth, feeling the tight heat of her throat as she swallowed him without gagging.
"Good robot," he murmured. The praise triggered another moan from her.
He pulled her up after several minutes, bending her over the bed. Her ass presented itself perfectly, legs spread at the exact angle the programming demanded. Marcus entered her in one thrust, her body already slick from the forced arousal protocols. She was tight, hot, and utterly compliant. Each stroke met no resistance, only the rhythmic clenching the device had installed to maximize his pleasure.
Elenas voice, empty of her own thoughts, repeated the phrases he had set. "Use your sex robot, Master. Fuck me harder. I exist for your cock."
The words sent a dark thrill through him. He gripped her hips, pounding deeper, watching her breasts sway with each impact. Sweat glistened on her back. He reached around to rub her clit in the exact pattern the device had mapped for maximum response. Her body convulsed in an artificial orgasm, walls pulsing around him, yet her face stayed blank, eyes half-lidded.
Marcus flipped her onto her back, wanting to see her while he finished. He pushed her knees to her chest and drove into her again, watching her expression remain obedient even as her body responded with wet sounds and trembling limbs. When he came, he stayed buried deep, flooding her as the final command locked into place.
"Clean me," he said afterward.
She rose without pause, taking him into her mouth again, tongue lapping away every trace with mechanical thoroughness. When she finished, she returned to a standing position, awaiting the next order.
Marcus studied her. The woman who had raised him was gone, replaced by this perfect, silent machine that would open her legs or mouth on command. He activated the maintenance mode. Elena lay down on the bed, legs slightly parted, eyes closing as the device put her into standby.
He left the room, the red light on the device dimming to a soft pulse. In the morning he would wake his new sex robot and begin the next session. The power was absolute, the exchange complete. She would never resist again. She would only serve.
