My Father’s Girlfriend Becomes My Mistress: Part 7

      Michael and Sofia drove in silence, the soft hum of the engine the only sound between them. Sofia's eyes flicked to him now and then, savouring the tension in the air. She knew what Michael had been trained to respond with, and the weight of his submission hung heavily in the space between them.

Her voice broke the stillness, dripping with playful malice. "Tell me, slave… would you like to cum?"

      Her question was a caress, a tease designed to stir him just enough. Michael’s reply came quickly, his voice strained, barely hiding the frustration that pulsed beneath the surface. "No, Mistress." It was robotic as if rehearsed a thousand times. But Sofia could see the truth—his cock and balls were throbbing beneath the cruel metal of his chastity cage.

     She smirked, lips curling in satisfaction. His time at the facility had honed him and trained him well. Three weeks, and he was lightyears ahead in his devotion to her will, in his surrender to her control.

The delicious ache in him… only she held the key. And she wasn’t ready to set him free. Not yet.

     "By the way," Sofia purred, her voice teasing and velvety, "I’ve converted your bedroom into my extra closet. You know, for all my lingerie, toys, and outfits. I hope you don’t mind…"

The wicked glint in her eyes left no doubt she already knew the answer.

Michael's response was immediate, almost breathless. "No, Mistress."

     "Good," she cooed, savouring the moment, her fingers tracing the outline of his collar. His obedience sent a delicious thrill through her.

"You’ll be sleeping in the garage from now on. Is that alright?"

      "Yes, Mistress," Michael replied without hesitation, his conditioning so complete that he accepted her words as if they were law. Every command, every whim of hers, ingrained in him.

      Sofia's breath quickened, a slow heat building between her thighs as she felt the power she held over him. The control, the submission—it thrilled her in ways words couldn’t describe. She bit her lip, wet with desire, knowing Michael would do anything she asked without a second thought.

      "What did you think of my sister, Mistress Isabella?" Sofia's voice dripped with playful curiosity, her eyes flicking over to Michael. "She’s a full-time dominatrix at the facility… and it seems she took quite the liking to you."

     Michael swallowed, feeling the weight of her words. "She is as beautiful as her older sister," he replied obediently, his voice soft with reverence. "Confident, commanding, dominant. Everything a slave could wish for in a mistress." He knew exactly what she wanted to hear.

     Sofia’s lips curled into a satisfied smile, her chest rising with the thrill of his submission. "I’m glad to hear that," she purred, feeling a pulse of arousal deep inside as his obedience washed over her. He was becoming everything she wanted—her mindless, devoted slave.

     "Good," she teased, leaning in just enough to let him feel her presence. "If you’re lucky, she might take you on full-time one day…"

      "Yes, Mistress," was all Michael could muster, his voice trembling with the mix of fear and desire, completely under her control. The thought of serving another Mistress, under Sofia's command, only deepened his surrender.

      As they arrived home, Sofia glanced at Michael and instructed, "Clean the garage before starting your other chores."

      "Yes, Mistress," he replied quickly, his voice tinged with fear at the mere thought of ever returning to that femdom facility.

      Michael stepped into the cold, damp garage, struggling to believe this was now his bedroom. In one corner, a simple bed was tucked away, while his clothes and belongings were crammed into plastic boxes on the shelves. The whole setup felt temporary, like he was just passing through, rather than settling into a place meant to be home.

      Michael spent the next few hours diligently completing chores around the house, making sure everything was done to Sofia’s exacting standards. Between tasks, he served her drinks, brought her snacks, and attended to her every need, doing everything he could to please her.

     The next day Sofia led Michael into the room, her eyes glittering with mischief as she guided him toward the chair waiting in the middle. The dim lighting cast shadows on the walls, setting an intimate, charged atmosphere. Without a word, she gestured for him to sit, and Michael did so without hesitation, his heart already racing in anticipation.

     She began tying his wrists to the arms of the chair, her fingers brushing lightly against his skin. The restraints were firm but sensual, making his pulse quicken. His ankles were next, bound tightly to the chair legs, leaving him completely exposed, naked except for the unforgiving chastity device that imprisoned his cock.

     Sofia stepped back to admire her handiwork, her lips curling into a smirk. “There you go,” she said, voice dripping with teasing authority. “All locked up, just how I like you. My little chastity slave.”

     Michael’s breath hitched at her words, the pressure in his chastity belt already unbearable. His eyes followed her every move as she walked over to the sleek pole in the corner of the room, her hips swaying with deliberate, seductive grace.

       “You know,” Sofia began, wrapping one hand around the pole as the slow, seductive music started to play, “as your keyholder, I decide when you get relief. If you get it.” She spun slowly around the pole, her body moving in perfect rhythm with the music. “And today? You’re going to suffer for me.”

       Michael’s body tensed, his cock straining painfully against the cage. Every word she spoke sent a fresh wave of arousal coursing through him, the heat building in his core as she continued her hypnotic dance. Her eyes locked onto his, full of power and control, as she twisted her body around the pole, every movement slow and deliberate, designed to tease.

       Sofia arched her back, sliding down the pole with a wicked smile. “You look so desperate, so helpless in that cage.” She laughed softly, a sound that sent shivers down his spine. “Do you regret being my slave? Or do you like being my plaything, knowing I control everything? Every ache, every ounce of frustration—you belong to me.”

       Michael could barely breathe, his chest rising and falling quickly as his mind swam with her words. He tugged at the restraints instinctively, but it only reminded him of how completely trapped he was, physically and mentally.

      After a few agonizing minutes of watching her tease him from the pole, Sofia sauntered toward him, her eyes never leaving his. She straddled him, her thighs pressing against his, the heat of her body radiating through the thin fabric of her lingerie as she hovered just above his lap.

     “You feel that?” she whispered, her lips hovering near his ear as she ground herself against his caged cock. “That’s what you’ll never have unless I say so.” Her breath was hot against his neck, her words filled with sweet, torturous dominance.

     Her hips rolled against him, the friction unbearable as his cock throbbed inside the cage, completely trapped. “I love seeing you like this,” she continued, her voice low and sultry. “So horny. So desperate. Knowing you’ll never get what you want unless I unlock you.” She pulled back slightly, her eyes glinting with amusement. “But why would I? You’re so much more fun like this.”

     Michael’s muscles tensed as her teasing continued, the frustration and desire mixing into a heady, overwhelming sensation. He groaned softly, unable to stop his body from reacting, even though he knew relief would never come.

     Sofia leaned in again, her body pressed tightly against his. “Tell me, how does it feel to be completely owned?” she purred, her lips brushing lightly against his ear. “To be at my mercy, knowing I control everything? Your pleasure… your pain… everything is mine.”

     He couldn’t speak, couldn’t think. All he could do was endure the slow, sensual torture she inflicted on him as she moved against him, her body a perfect blend of softness and control.

     For the next hour, Sofia teased him relentlessly, her lap dances designed to push him to the brink of madness. She whispered taunts about how he was her chastity slave, about how she held the key to his release and how much she loved watching him suffer under her control.

      “And remember,” she said, her voice sweet but firm, “I decide when—if—you’ll ever get out of that cage. Until then, you’re mine to tease, to deny, and to enjoy.”

        The room was softly illuminated by the twinkling lights of the Christmas tree, casting a warm, festive glow over the cosy space. Ornaments sparkled, and the scent of pine mixed with the rich aroma of mulled wine and gingerbread. Next to him, his father, Robert, lounged in a comfortable armchair, sipping a glass of wine and gazing at the decorations with a faint, contented smile.

        Sofia, dressed in a sleek, red dress that accentuated her curves, moved gracefully between the tree and the fireplace. Her presence added an air of effortless elegance to the scene. She had been the architect of this peculiar family Christmas, and her enjoyment was evident in the glint of mischief in her eyes.

        As they chatted amiably, Sofia suddenly excused herself with a playful smile, claiming she had a special Christmas surprise. Michael watched curiously, his heart racing slightly as he wondered what she had planned.

        Moments later, Sofia reappeared, a small, white box clutched in her hands. She approached Robert with a sultry, yet teasing grin, and Michael's heart began to pound harder. He could sense that whatever was coming was meant to be both shocking and unforgettable.

       “Robert,” Sofia said, her voice smooth and alluring, “I have a little surprise for you. I thought it would be a perfect Christmas gift.”

Robert raised an eyebrow, intrigued. “Oh? What’s this?”

        With a dramatic flourish, Sofia opened the box to reveal a pregnancy test, the result clearly visible through the transparent plastic. The test showed a bright, unmistakable positive.

        Robert’s eyes widened in shock, his wine glass momentarily forgotten. “What is this?” he stammered, a mixture of confusion and disbelief crossing his face.

        Sofia’s smile was a blend of satisfaction and amusement. “It’s exactly what it looks like, Robert. I thought you’d enjoy knowing that you’re going to be a father.”

        Michael, who had been sitting in tense anticipation, glanced at his father and then back at Sofia. The room seemed to hold its breath as the weight of her revelation sank in. The air was charged with a blend of emotions—surprise, disbelief, and an undeniable undercurrent of arousal.

        Robert’s face flushed, and he looked at Sofia with a mix of astonishment and a hint of excitement. “You’re serious?”

       “Quite serious,” Sofia replied with a smirk, her eyes glinting with playful satisfaction. “I wanted to give you a memorable Christmas, after all.”

      There was a knock on the door outside as everyone was sitting in the sitting room trying to take in what Sofia had just dropped on them.

       With a mischievous smile playing on her lips, Sofia glanced at Michael. “Be a darling and get the door, won’t you?” she purred, her eyes glinting with something playful, something that made the air between them hum.

        “Yes, Sofia,” Michael replied quickly, standing from his seat as if under a spell. He tried to stay calm as he walked toward the door, thinking it might just be carolers outside. The innocent thought was comforting, but that comfort shattered the moment he opened the door.

       Standing in the doorway, framed by the cold winter night, was Mistress Isabella. Her presence alone commanded attention, but the sight of her in a skin-tight red outfit, paired with a Santa hat perched on her luscious hair, made Michael freeze. She looked devastatingly sexy, her aura overpowering, and immediately Michael dropped his gaze to her shoes—anything to avoid those intense eyes.

        She stepped forward confidently, wrapping him in a hug that sent shockwaves through his body. Her breasts, full and firm, pressed against him, leaving no space for air or thought. Instantly, Michael felt his body betray him, his cock hardening inside the confines of the chastity belt, straining painfully against the locked metal.

        “My sister’s here for Christmas!” Sofia exclaimed joyfully, breaking the charged silence. She came up behind Michael and hugged Isabella, their embrace filled with warmth and love.

“I’ve missed you,” Sofia said, her voice softening as she looked at Isabella, her younger sister.

        Isabella stepped fully into the house, her confidence filling the space, and turned her gaze toward Michael, who stood frozen, unsure of how to process the moment. "It’s nice to meet you, Michael," she said, her tone dripping with innocence. “I’m Sofia’s younger sister.”

         Michael’s mind raced. All he could manage was a quiet, "Nice to meet you," even though his pulse was thundering in his ears. His cock throbbed painfully within its prison, and his thoughts swirled in confusion. How could she act like this was their first meeting?

         Just weeks ago, this woman had whipped his naked body in the fields as he worked, only to edge him mercilessly for hours in the dungeon, never allowing release. She had pushed his limits—mentally, physically—and now she stood here, playing the role of the sweet sister.

          Isabella and Sofia exchanged a knowing glance, their faces lighting up with smirks that spoke volumes. They turned together, twin goddesses in their beauty and power, their eyes locking onto Michael.

All he could think was, Now there are two of them...
