The 25-Year IVF Trap My Cheating Wife Raised My True Love's Son

My wife couldn't get pregnant, so we decided to try IVF. Right before the embryos were created, I caught her secretly swapping my sperm sample with her first love’s. I didn't make a scene. I quietly switched my sperm back. And while I was at it, I also swapped her eggs with my comatose ex-girlfriend’s. Twenty-five years later, my wife’s first love showed up at my doorstep, reaching for my son with tears in his eyes: "My sweet boy, I'm your real father!" My son, River, and I walked through the front door after returning from an overseas medical conference, only to freeze in our tracks. The living room was packed. Distant relatives we hadn't seen in years were crammed onto every sofa and chair. Looking at this crowd, you’d think the Sterling family was holding an emergency board meeting. The most glaring sight was Julian Rivers, sitting dead center on the couch, his eyes rimmed with red. Selena, my "devoted wife" who rarely bothered coming home, was wrapping an arm around him, murmuring soft words of comfort. I raised an eyebrow, set my suitcase aside, and looked at her. "What's the special occasion? Quite a crowd we have here." River stood right behind me, arms crossed, staring down at Julian with pure disgust. He had already pieced together who this man was. My mother-in-law, Margaret, sat in the main armchair. Her face was dark, her lips pressed into a tight line. Before Selena could say a word, Julian lunged off the couch, weeping as he threw himself toward River. "My boy! My precious son, I'm your biological father!" River dodged him with effortless grace, his brow furrowed in utter revulsion, looking at Julian like he was a pile of trash. Stepping back, River's voice cut through the room like ice. "My dad's name is Ethan Cole." Good boy. He never failed to have my back. I placed a reassuring hand on River’s shoulder, then stepped forward and drove my fist straight into Julian’s face. Thud. The sound of the punch echoed through the silent room. "Watch whose family you're claiming," I said coldly, my gaze sharp as a blade. Selena jumped to her feet, frantically helping Julian up before pointing an accusing finger at me. "Ethan, are you out of your mind?! How dare you lay a hand on Julian?!" She raised her palm to slap me. River reacted instantly. He stepped in and slapped Selena across the face before she could even touch me. "You dare touch my dad?" River’s voice wasn't loud, but it carried undeniable authority. Selena froze, trembling with rage, and raised her hand again to strike River. Julian grabbed her arm, putting on a tearful, saintly act. "Selena, don't! That's our son!" Watching him play the loving father made me want to throw up. Selena dropped her hand, glaring venomously at River. "If it weren't for your real father standing right here, I’d teach you a lesson you'd never forget!" River scoffed. "Oh? I’d love to see you try." That piercing, unyielding look in his eyes was identical to mine when I was young. I felt a surge of pride. That's my boy, raised by my own hands!One of the senior family elders cleared his throat, trying to regain control over the chaos. "Quiet down, everyone!" His deep voice demanded silence. The room fell still, all eyes shifting to him. He turned toward Selena. "Selena, you called this family meeting. What is this all about?" Selena took a deep breath, as if gathering all her courage. She wrapped an arm around Julian’s shoulders, putting on a display of eternal devotion. "The truth is, I have an important announcement to make today." She paused, scanning the room before locking eyes with River and me. I watched her quietly, waiting to see what kind of clown show she was about to perform. "River... he isn't Ethan’s biological son." Her voice wasn't loud, but it dropped like a bomb in the living room. River snapped his head toward me, his eyes wide with shock. I gave him a subtle look, telling him to stay calm. Whispers broke out among the relatives like sharks catching the scent of blood. "Years ago, when we did IVF..." Selena said, pausing as if the memory was too painful to bear. "The doctors told me Ethan's sperm quality was practically zero. I couldn't bear to break his heart... so to give him a child, I secretly swapped it with Julian's..." The sheer audacity of this woman. She pulled a dirty trick back then, and now she dared to spin it as an act of mercy while throwing dirt on my name! Selena eyed me with malicious intent, clearly waiting for me to lose my temper and break down. Instead, I stood there completely unbothered. Seeing no reaction, she had no choice but to keep acting. "I gathered everyone here today to witness this moment," she said, gazing tenderly at Julian. "River needs to be reunited with his true father." The room exploded into chatter. "If River isn't Ethan's, then of course he should go to his real dad!" "Exactly. Ethan has held the position of Sterling son-in-law for way too long. Time to step aside!" "He’s been running Sterling Enterprises for decades. Now that the truth is out, he should be stripped of his CEO title!" Listening to their venomous remarks, I sneered inwardly. Over the past few years, I had ruthlessly purged these greedy relatives from the executive board, leaving them with nothing but annual dividend checks. They hated me for it. Now, they were drooling at the prospect of Selena and me tearing each other apart so they could swoop in and reclaim a piece of the pie. Seeing the naked greed in their eyes, River tightened his grip on my arm. I spoke up, my voice calm but ringing with finality: "River is my son. And only my son." Julian put on a helpless, heartbroken expression and sniffled. "Ethan, how long are you going to keep lying to yourself?"I wasn't lying to myself. River was, without a shadow of a doubt, my flesh and blood. Did Selena and Julian really think they had pulled one over on me? Twenty-five years ago, when Selena struggled to conceive, we turned to IVF. Right before the fertilization process, I caught her red-handed bribing a lab technician to tamper with my frozen samples. I even overheard her giddy phone call to Julian, boasting that she had successfully swapped in his sperm. I didn't confront her. Instead, I quietly paid the chief embryologist a cool hundred grand to put my backup sample back in place. And while I was at it, I had the doctor swap Selena’s eggs with those of my comatose ex-girlfriend. On the day the embryos were successfully formed, Selena and I witnessed the "miracle" together. She was practically glowing, genuinely believing she was carrying a child born of her and Julian. Watching her ecstatic face back then almost made me burst out laughing. For twenty-five years, I watched her play the dutiful, doting mother to River like a fool on a stage. You have no idea how satisfying it was. She thought she was setting a trap for me, completely unaware that she had been raising another woman’s child for over two decades. Selena sneered, cutting through my thoughts. "Still in denial? River might have grown up by your side, but biologically, he’s not yours! Julian is his real father." My expression remained neutral, laced with mockery. "Are you dreaming out loud?" "If you don't believe me, let's take a DNA test!" Selena snapped, her chin held high. "And I want a divorce! You forced me into this marriage twenty-five years ago. I've endured you as a pathetic shadow for long enough. I've done more than enough for you!" When she mentioned divorce, a gleam of triumph flashed across her face. She had clearly been planning this for years. She dared to say she had done enough for me? In the twenty-five years since I married into her family, we had slept in separate bedrooms. While I was raising the child alone, she was off secretly gallivanting with Julian. While I was breaking my back in the boardroom to keep the Sterling empire afloat, she was blowing fortunes at high-end clubs. She had one thing wrong, though. I never married her out of love. I married her solely to secure legal standing within the family and take full control of Sterling Enterprises. Now, the entire company was under my thumb. Selena had outlived her usefulness. "I'm fine with a divorce," I said, giving a casual shrug. "As for the DNA test, there's no need. I know River is my son." River looked at me, his gaze firm. "Dad, I trust you." Selena and Julian instantly panicked. "River, don't you even believe your own mother?!" River ignored her completely, stepping closer to my side. Right at that moment, a young man who looked like a college student barged through the front doors. He rushed straight toward River, calling out with tearful excitement, "Brother!" The entire room went dead silent. Having an extra father show up out of nowhere was wild enough—now there was a secret brother too?I took one look at the boy's face, noting the striking resemblance to Julian, and immediately knew who he was. This had to be Selena and Julian's secret lovechild. They had hidden him well, keeping him completely out of sight for over twenty years. This family drama was turning out to be far more entertaining than I expected. Margaret, sitting at the head of the room, fixed her sharp gaze on the boy. "Selena, what is the meaning of this?" The room froze again. The boy’s eyes reddened, looking on the verge of tears. "Brother, my name is Gavin. I... I've always known you existed." His voice trembled slightly as he spoke with a timid stutter. He shot a nervous glance at me before quickly lowering his head, looking like a frightened puppy. "My... my dad always talked about you. He said you were amazing, handsome, brilliant..." Right on cue, Julian began to weep softly, his shoulders shaking. "River, my baby boy... I've missed you so much all these years..." He lifted his tear-stained face, acting as though he had suffered the greatest injustice in the world. "Gavin... he missed you too. We used to watch you from afar all the time..." Gavin nodded vigorously, chiming in with desperation, "It's true! Brother, I even enrolled in your alma mater just so... just so I could feel closer to you..." He pulled a thick stack of photos from his coat pocket and offered them to River with trembling hands. "These are pictures of you... I took them secretly..." River took the stack and flipped through them. There were photos of him smiling in his graduation cap and gown, looking exhausted after basketball practice, fiercely debating in a mock trial... River’s skin crawled. A creep had been stalking him and taking surveillance photos of his life for years! Selena didn't waste a second. She hurried over to Margaret, pointed at Gavin, and spoke with heavy emotion. "Mom, this boy carries Sterling blood! With the whole family here to witness it today... please, acknowledge him!" Selena thought she was being clever. She knew that after her father passed away, Margaret held the final say in the family. Calling all these relatives over was her way of publicly cornering Margaret into accepting the boy. She was betting that if Margaret accepted Gavin into the family, I wouldn't have a leg to stand on. After all, over the last twenty-five years, she had watched me treat Margaret with nothing but utmost respect and filial devotion. Gavin caught on fast. He immediately turned toward Margaret and bowed politely. "Grandmother!" Margaret stared at Gavin, then glanced at me, her expression guarded and complex. She didn't respond to him. I knew she cared about me and felt awful about what was happening. Not wanting to put her in an awkward position, I spoke up and broke the tension. "Selena, getting this bastard recognized so he can inherit the Sterling estate is your real goal, isn't it? Why drag River into this?"
