My Father’s Girlfriend Becomes My Mistress: Part 3

     Michael lay in bed, his body slick with sweat and trembling uncontrollably. The chastity belt pressed mercilessly against his aching cock, which felt like it was about to explode. The intense, persistent pressure had made his balls swell to an almost unbearable size, each pulse sending waves of frustrated desperation through him. He could barely move, the sheer need to cum consuming every part of him.

     As he lay there, his breathing came in ragged gasps, and his muscles twitched with the strain of his arousal. His mind raced with thoughts of release, each moment of restraint only heightening his agony. His skin glistened with sweat, and every shift in position only intensified the torturous need that seemed to envelop him entirely.

     The sensation was maddening, his whole being focused on the cruel and unyielding pressure of his swollen balls, trapped in a cycle of relentless, unbearable desire.

     I have to convince my father to propose to Sofia as soon as possible he cried out to himself as he felt like his balls were becoming so heavy, they would weigh him down as he walked.

      Michael stepped into the kitchen, his breath catching at the sight before him. Sofia was wearing a skimpy, pink maid’s outfit that barely clung to her curves. His body responded immediately, his cock straining against the chastity belt, the sharp sting of the pins inside reminding him of his helpless state. His swollen, aching balls felt impossibly heavy, the frustration making him dizzy.

     “Good morning, Michael,” Sofia greeted him with a teasing smile, her full breasts nearly spilling out of her tight dress as she moved. Her voice was soft, sultry, dripping with playful seduction.

     Michael, trying to remain composed and respectful, managed a strained, “Good morning, Sofia… that’s a, uh, lovely outfit.”

     “Thank you, Michael,” she purred, stepping closer. Her eyes sparkled with mischief. “I want your father to know I’m here to serve his every need… inside and outside the bedroom.”

      Her words lingered in the air, thick with promise, and Michael’s frustration deepened, knowing just how powerless he was in the situation.

     Michael's father entered the kitchen, his eyes lighting up as they landed on Sofia. He let out a low, appreciative whistle. "Oh my god, Sofia, you look incredible."

      Sofia gave a playful roll of her eyes, her lips curving into a teasing smile. "This old thing?" she said with mock innocence before her voice dropped into a seductive purr. "You know I’m here to serve your every need, Papi." Her words dripped with sensuality, the way she called him Papi in that soft, accented tone sending a shiver through the room.

      She sauntered toward him, her body moving in a way that drew every eye and wrapped her arms around him, pulling him close. Michael’s father melted into her embrace as her full, heavy breasts pressed against him, his face completely lost in her voluptuous cleavage.

        Michael could hardly believe his eyes. Sofia, with her sultry Latina accent, was calling his father Papi as she settled into his lap, her fingers delicately feeding him strawberries. Each bite was slow, sensual, and deliberate as if teasing Michael with every lingering moment.

       His jealousy burned inside him. Here was this Colombian goddess—his father’s maid by day, his plaything by night—lavishing him with affection while Michael sat there, locked in a steel chastity belt, throbbing with frustration. The worst part? He knew he had no chance of release, no hope of relief, unless his father decided to propose to her. And until then, he was left to watch, helplessly craving what he could never have.

       Sofia glanced up at Michael with a teasing smile, her dark eyes gleaming. "Oh, Michael, be a dear and run a few errands in town for me this morning, won’t you?" she cooed, her voice dripping with seduction as she handed him a piece of paper. Michael’s heart sank as he glanced at the list that had lots of tasks written down, each one more humiliating than the last.

"Yes, Sofia, I’d love to," he replied, his voice strained with forced politeness.

       Sofia stood up, her curves on full display as she took his father’s hand, pulling him toward the bedroom. She spoke to him in soft, rapid Spanish, her tone so sensual it made Michael’s pulse race. He watched helplessly as they disappeared behind the door, leaving him on his errand list.

       By the time Michael was leaving, he could hear Sofia from upstairs. Her moans echoed through the house, growing louder as she screamed in Spanish, her voice filled with orgasmic pleasure. The sound of her calling his father Papi over and over again pierced through the walls, leaving Michael both embarrassed and leaking from his cage.

Michael looked at the errand list and groaned as he scanned the tasks, each one more humiliating than the last. His face burned with embarrassment as he read:

•  Buy tampons for Sofia, making sure to get the exact brand and size she prefers.

•  Restock Sofia’s make-up supplies, including her favourite shade of lipstick and foundation.

•  Pick up Sofia’s new lingerie set from the boutique, complete with a lace bra, thong, and stockings.

• Buy condoms for his father, knowing exactly what they would be used for.

•  Pick up a waxing kit for Sofia, including body wax strips and aftercare lotion.

•  Purchase a set of sexy handcuffs from the adult store, as per Sofia’s specific request.

•  Replace the batteries in Sofia’s favourite vibrator, by asking the employee in the adult store for the correct battery.

•  Stop by the spa to book a couples massage for Sofia and his father.

• Collect Sofia's sexy burlesque photos from a photo shoot for a present for his father. 

       Each errand felt like an escalating wave of humiliation, washing over Michael as he reluctantly trudged out the door. With every step, the weight of his throbbing blue balls felt unbearable, swinging heavily between his legs as if they were about to explode. The chastity belt pinched painfully, a constant reminder of his torment.

       His mind raced with each humiliating task: buying Sofia's tampons, restocking her favourite makeup, picking up the delicate lingerie that would cling to her body later that night—all while knowing it wasn’t for him. The worst of all was purchasing condoms for his father, a cruel reminder of his own aching frustration.

       By the time Michael finally returned home, his legs trembled, and he wished for nothing more than for his cock and balls to fall off, the torment driving him to the brink of insanity.

      Michael was walking down the hallway towards his bedroom when he heard the unmistakable sound of drilling coming from his father's room. Curiosity piqued, he approached the door, his footsteps muffled on the carpet. As he nudged the door open and peeked inside, he was taken aback by the sight before him.

       In the middle of the room, a team of builders was hard at work, installing a sleek, polished stripper pole. The metal pole gleamed under the bright lights as they carefully secured it, drilling it into both the floor and the ceiling. The room buzzed with the sound of power tools and the hum of conversation.

      One of the builders wiped sweat from his brow and chuckled, "Wow, this guy must be one lucky son of a bitch."

      Another builder grinned and nodded in agreement, "Yeah, I’ve installed a lot of these, but this is the first time I’ve seen it in a place like this. He must be having quite the party."

       Michael stood frozen in the doorway, his face flushed with a mix of embarrassment and confusion. The builders continued their work, oblivious to his presence, while Michael’s mind raced, trying to process the scene unfolding before him.

      A few moments after the builders left, Sofia called Michael from his father’s bedroom. He swallowed and slowly opened the door to the room before his mouth hit the floor.

     Sofia was standing there in her underwear as she approached the stripper pole and began to swing around it and do very sexy and complex moves on the pole.

     Michael felt his cock practically explode in the chastity belt as he witnessed her amazing firm and curvy body swing around the pole.

     She then slowed down and seductively stood next to the pole as she said it’s a surprise for your father. I hope he likes it as I plan to fulfil every one of his sexual fantasies and be his little slut she giggled.

     Michael felt lightheaded as a wave of intense pressure surged through his blue balls, each throb magnifying his frustration and desire. The sight and sounds coming from Sofia were driving him wild.

     As she moved towards the pole to begin another routine, she glanced back at him with a wicked smile. “I hope you’ve been preparing to convince your father to propose to me, slave. I bet your balls are all swollen and aching, just ready to burst,” she teased, her wink filled with both mockery and promise.

     She removed her bra with a seductive flick of her wrist, her gaze locked on Michael as she gave him one last, knowing wink. “Now, leave,” she commanded softly, her voice dripping with authority and anticipation.

      Michael sat across from his father at the dining table, his hands fidgeting nervously with the edge of his napkin. The room was quiet, save for the occasional clink of silverware as his father finished his meal. Michael took a deep breath, knowing this was a conversation he couldn’t afford to mess up.

       “Dad, there’s something I need to talk to you about,” Michael began, his voice earnest but tinged with a hint of hesitation. His father looked up, sensing the seriousness in his tone.

      “I’ve been thinking a lot about Sofia,” Michael continued, trying to keep his emotions steady. “I know she’s been a big part of your life lately, and I can see how much happier she makes you. I’ve never seen you this... well, content and at ease. She’s not just a great partner; she’s someone who really gets you, who supports you and brings out the best in you.”

      Michael’s father stared at him, his brow furrowed in contemplation. The silence between them was thick, charged with the weight of Michael's impassioned plea. Michael's heart pounded in his chest, his body still thrumming with the frustration of his chastity belt. He could barely keep still, his legs twitching slightly as he awaited his father's response.

      After a moment that felt like an eternity, his father’s expression softened. “You really believe that, don’t you?”

      “Yes,” Michael replied fervently, his eyes locking onto his father's with earnest intensity. “Sofia is extraordinary. She’s supportive, and she brings out the best in you. She’s more than just a partner; she’s someone who completes you in a way that no one else could. I don’t want you to lose something so special just because of hesitation. Propose to her, Dad. Don’t let this chance slip away.”

       His father’s gaze grew distant as he processed Michael’s words, the gravity of the situation sinking in. Michael’s pulse raced with a mix of anxiety and hope, his chest tightening as he watched his father’s face. The silence was finally broken by a deep, thoughtful sigh. “I’ll think about it,” his father said, his voice thoughtful and a touch uncertain.

      The next morning Michael came downstairs feeling like he was actually ill. His cock was trying to grow in the catch as if it was scrabbling for oxygen. His balls felt like balloons with too much air in them. He never knew blue balls had a pulse, but he had a massive throbbing sensation in his balls.

      He took a breath before entering the kitchen as he heard his father and Sofia having a conversation.

      They both said hello as Michael entered the room and Michael let out a little groan as he saw the key to the chastity belt nestled between Sofia’s massive tits at the end of a long necklace. She was wearing a long coat and asked Michael if he would like to go to lunch together.

     Michael knew he couldn’t refuse, especially with the key tantalizingly nestled between Sofia's perfect breasts. The sight of it there drove him wild with longing.

     "I’d love to go to lunch with you, Sofia," he said, his voice tinged with eagerness. Though his excitement was really about the key hanging just out of reach around her neck.

      After finishing breakfast, they headed out to Sofia’s jeep. As they drove towards the outskirts of town, she chatted animatedly about how excited she was for Halloween next month. She spoke of elaborate costumes and the fun they would have as a family, her voice warm and inviting.

      Michael struggled to focus, trying his best to be on his best behaviour. The key, which had been a distant fantasy for weeks, was now so close, yet still just out of reach. Sofia had made it clear: he wouldn’t experience any release until his father proposed to her.

      They pulled up outside some empty buildings beside a river and Sofia led Michael inside one of them. They walked down an empty corridor before Sofia stopped at a large metal door. She inserted a key and opened the door before ushering Michael inside.

     Michael walked into the dark room and heard the door close behind them before Sofia hit the light switch and the room lit up with red lights. It was a sex dungeon...

      The walls were adorned with whips, floggers, canes, gags, hoods, shackles, cuffs and hundreds of other sex toys.

     Michael turned around to Sofia and saw her remove her coat, revealing a tight black latex dominatrix outfit underneath.

     "You’ve been a naughty boy, Michael," Sofia said with a sultry smile. "And naughty boys need to be punished."

     Michael's throat tightened as he tried to explain that he’d spoken to his father about proposing, but Sofia cut him off with a sharp crack of her riding crop against the floor. The sound reverberated around the room, sending a shiver down his spine.

"Strip, slave!" she commanded, her voice firm and commanding.

     Michael’s cock twitched in the chastity cage as he hurriedly peeled off his clothes, which Sofia swiftly tossed into a bin. His heart raced as she shackled his wrists behind his back and locked cuffs around his ankles. The collar she placed around his neck felt both humiliating and thrilling.

     Sofia guided him to a bench, her touch both firm and teasing. She secured him in place, his body exposed and vulnerable. With deliberate movements, she reached for a long wooden cane hanging on the wall. Her steps were slow and seductive as she approached him, making his pulse quicken.

     Michael’s breath hitched as he felt the cane brush against his ass, the anticipation almost unbearable. Then, with a sudden, sharp smack, the cane struck his rear, sending a jolt of pain and pleasure through him. He yelped, his body arching in response, as Sofia’s gaze remained fixed on him with a mix of satisfaction and desire.

     Sofia's voice was a sultry whisper of authority as she declared, "It will be fifty canings for you, slave, since your father hasn’t proposed yet." She drew back the cane, her eyes gleaming with anticipation.

     With each sharp smack, Michael was forced to cry out, "Thank you, Mistress," his voice trembling with a mix of pain and submission. The sting of the cane left his ass burning, the punishment relentless as Sofia maintained her steady rhythm.

     When she shifted her focus, Michael's heart pounded with dread. Sofia attached weights to his balls, the metal pulling them down in a relentless, agonizing pressure. She then added close pegs to his stretched skin, the sensation making him writhe in discomfort. His attempts to yell were stifled as she shoved a large black dildo gag into his mouth, silencing his protests.

     Hours dragged on as Sofia continued to punish him, her voice cutting through the haze of pain and pleasure. "You failed to convince your father to propose," she reminded him, her tone a mix of scorn and pleasure.

     Finally, she released him from the bench and directed him onto his hands and knees. With deliberate cruelty, she fastened a wooden humbler around his cock, balls, and legs, ensuring he couldn’t stand. The weight of the humbler combined with the torment of her whip as she cracked it against his restrained body.

     Michael was made to crawl around the room, his movements awkward and strained. Sofia commanded him to sit like a dog, lie down like a dog, and beg and bark like a dog. Each command was a humiliating reminder of his complete surrender.

     Despite the intense humiliation, Michael’s body betrayed him as strands of precum leaked from the chastity cage, a testament to his conflicted desire and torment.

     When Michael was a quivering mess on the floor kissing her boots, she reminded him he wouldn’t be cumming until his father had proposed.

     Michael couldn't believe his life right now. His father was living his wildest fantasies having incredible sex several times a day with this gorgeous Colombian goddess who fulfilled every one of his wildest fantasies while she secretly had Michael locked in chastity and dominated him in sex dungeons while whipping him and making him bark like a dog as she punished him.

     Sofia removed the cuffs and shackles and threw some pink women’s leggings and a pink jumper at Michael and told him to put them on like the sissy slave he is.

     Michael quickly obliged and felt embarrassed to be wearing women’s clothing as he followed Sofia out of the dungeon. His cock and balls were blue and bruised, but he couldn’t keep his eyes off her thick firm ass in her latex pants.

     When they got home Michael collapsed onto his bed wishing this never-ending nightmare would come to an end.

     Michael’s father left for the weekend with a massive smile on his face. Michael thought he would have the house to himself for a few days but Sofia informed him she would be spending the weekend with Michael.

      Once his father left, she stripped him down to his chastity belt and cuffed him to the stripper pole in his father’s bedroom. To make matters worse she placed her wet panties over his nose so he was forced to inhale her sweet pussy juices while his cock and balls strained in the chastity belt. It was a horny living nightmare for Michael.

     After several hours Sofia walked into the room in full body latex, her breasts practically exploding from her chest and her ass sculpted from marble. She was a Colombian goddess who had Michael as her little bitch.

       She glided towards Michael, her heels clicking sharply against the marble floor as her hips swayed enticingly. Her gaze was a mix of amusement and dominance. “Well, well, you’ve been quite the obedient slave lately, haven’t you?” she purred.

       “Yes, Mistress,” Michael replied, his voice barely more than a whisper, a touch of desperation in his tone.

       She extended one foot towards him, and he leaned forward, pressing his lips against it, his face stretched in submission as his hands remained shackled to the stripper pole. She then extended her other foot, and he eagerly lavished it with kisses, his lips brushing the smooth skin as he tried to convey his devotion.

     She gave his locked balls and cock a playful, teasing kick, a mischievous glint in her eyes. “Those balls must be getting nice and full, slave,” she purred.

      “Yes, Mistress,” he managed to reply, his voice strained as he felt his cock throb and press desperately against the cage.

"I have good news for you, my submissive she teased. Things are about to change around here."
