A One Night Mistake With The Cold Billionaire

Katherine pov I waved my colleagues off as I stood outside the company building, the weight of the day’s work lifting off my shoulders. The evening air felt cooler now, the scent of rain thick in the air, and I could see the storm clouds rolling in. I grabbed my coat tighter around me, already bracing for the downpour that was about to come. The sky had been threatening all day, and now the first few drops of rain were falling, quickly turning into a heavy downpour. I checked my bag in frustration. Of course, I’d forgotten my umbrella. My hand brushed across my bag again, hoping to find it, but no luck. I sighed, shaking my head. “How could I forget something so simple?” But I wasn’t about to let something as small as rain ruin my mood. Today wasn’t just any other day. No, today was the day Felix would finally return from his business trip. Three weeks. Three long weeks of longing, of missing him, of counting the hours until I could finally hold him again. And now, finally, he was coming home. I stepped into the first available taxi I could find, hoping to get to his house quickly. The rain beat heavily on the windows, and I couldn't help but fidget in the back seat as the driver muttered about traffic. But I didn’t care. I was too excited to let his grumbling bother me. All that mattered was getting to him. When the taxi finally stopped in front of Felix’s mansion, I nearly jumped out before the driver even had a chance to fully park. I paid him quickly, barely waiting for him to hand me the change, and rushed up the steps to the front door. I was so eager to see him, to be in his arms again, to feel the warmth of his embrace. The rain had started to fall harder now, soaking through my clothes in seconds. I hardly cared. I was finally going to see Felix. I dug around in my bag for the spare key I always kept for his house, but when I found it, I noticed something odd. The house felt... too quiet. Felix usually left some music playing, the sound of his favorite jazz songs filling the space, but now there was only silence. “Felix?” I called out softly as I pushed the door open. No answer. My heart began to race. He had to be here. He’d just returned, and I knew how much he hated being away from me. He must’ve just been upstairs or in the kitchen. I was sure of it. I stepped into the hallway, glancing around, hoping to see him. The house felt cold without him. I shook off the uneasy feeling creeping up my spine and made my way toward the kitchen, hoping to find him there. But the kitchen was empty, save for a few leftover containers on the counter. It was odd. Felix loved to cook, especially when he’d been away for a while. He’d usually make something to unwind, something special just for himself. But there was nothing here. I frowned, starting to feel that strange unease settle deeper in my chest. Something wasn’t right. I moved toward the stairs, my legs a little heavier than usual, my mind racing. Where was he? When I reached the top of the stairs, I paused, hearing faint sounds coming from behind Felix’s bedroom door. My heart skipped. Could it be him? Maybe he was just tired, resting after his trip. I reached for the door handle, ready to slip in quietly and surprise him, but when my hand touched the knob, I hesitated. The sound that met my ears wasn’t the typical one I’d expect. There was something... intimate about it. My hand trembled as I turned the knob slowly, pushing the door open just enough to peer inside. And then, everything stopped. There, on the bed, was Felix. And next to him, my sister, Diana. I froze. I couldn't breathe. My mind refused to process what my eyes were seeing. Felix, the man I loved, was tangled in the sheets with my sister. They were having s*x their bodies clapping together in a rhythm. My stomach turned violently as I stepped back in disbelief. No. This wasn’t real. I had to be dreaming. It couldn’t be true. But as I stood there, the sickening reality of it all sunk in. I wasn’t dreaming. Felix’s back faced me, and Diana was lying beneath him, her body writhing with pleasure, his hands on her groaning as he f****d her.I felt like the world was spinning out of control as I stared at them. They didn’t hear me. They were too lost in their own world of pleasure,Felix was too engrossed in her to notice me standing there, changing positions to continue their actions. The moment the chocolates I had been holding slipped from my hands, hitting the floor with a muffled thud, Felix’s head whipped around, his eyes wide with shock. He jumped off the bed, his body still exposed, his face pale. “Katherine... this is... this isn’t what it looks like,” Felix stammered, his voice cracking. I couldn’t speak. My mouth went dry, my whole body trembling as I tried to wrap my mind around what I had just seen. Felix... my Felix, the one I had given everything to... and Diana... my own sister. Betraying me. In the worst possible way. Diana didn’t even flinch. She simply pulled the sheets tighter around herself, a look of disdain crossing her face as she eyed me. I could feel the anger bubbling up inside me, but it was nothing compared to the heartbreak. “Felix...” My voice cracked. “How could you do this to me? To us?” Felix opened his mouth, but nothing came out. He didn’t know what to say. How could he? How could he explain what was happening when there were no words to justify it? I turned away from them, my legs giving way beneath me. I stumbled back a few steps, my hands shaking uncontrollably. Diana’s voice broke through my fog of disbelief, sharp and cold. “I think I can have him now. Your time has expired, Katherine.” The words hit me like a slap to the face. I couldn’t even look at her. She wasn’t my sister anymore. She was just a stranger, a woman who had destroyed my life in a single act of betrayal. Tears stung my eyes, but I refused to let them fall. Not here. Not in front of them. I turned and ran from the room, not stopping until I was outside in the pouring rain. The cold soaked into me, but it didn’t matter. The pain inside me was far worse than the rain. I couldn’t breathe. I couldn’t think. I just had to get away. Away from them. Away from everything. I ran down the street, the rain pelting my skin, my mind spinning in a whirlwind of confusion and pain. I didn’t know where I was going. I just couldn’t be there anymore. Finally, after what felt like hours, I reached my parents' house. I collapsed in front of the gate, my heart still pounding in my chest. My body was shaking from the cold, from the rain, from everything that had just happened. I had nowhere else to go. No one else to turn to. I dragged myself to the front door, but when I stepped inside, the warmth of the house only reminded me of what I had just lost. The family I thought I had, the love I thought I had with Felix... it was all gone. I didn’t belong anywhere anymore.
