My mind dragged me backward whether I wanted it or not. The club. Low light. The way she had walked up to my table with that forced confidence, still smelling like nerves and expensive perfume. The way she laughed when I asked for a safe word and then gave me red anyway. How pretty she looked on her knees. How she sounded when I finally let her come. Best sex of my life and I didn’t even know her name. Then the next morning she was standing in my father’s foyer being introduced as my new stepsister and the universe decided to laugh in my face. Every time I saw her now the same thought hit me: mine. Even when I told her to forget it. Even when I edged her until she cried and then sent her awa

“Came twice already and still want more?” “Yeah,” I breathed, hips bucking into his fist. “Want you inside me again.” He kissed me to shut me up, pumping me faster. The slick sound filled the room, mixed with my muffled moans. I was horny as hell, and completely addicted to my own stepbrother. The taboo made it ten times hotter, knowing we could get caught any second only pushed me closer to the edge. Liam’s free hand covered my mouth as I got louder. “Shh, baby. Don’t want the staff hearing you moan my name again.”

I took a deep breath, preparing to unravel a past that connected us in ways Teresa likely never imagined. "You might want to sit down for this," I suggested, motioning towards a makeshift seat. Teresa complied, her eyes never leaving mine. "What could you possibly say that I haven't heard before?" I began cautiously, "Teresa, we're not just competitors or strangers. We're step-sisters." Her eyes narrowed, skepticism etched on her face. "Step-sisters? What are you talking about?" I took another deep breath, launching into the complex web of our shared history. "Our mother, who was once a part of Moonshade Pack, fell in love with a man she believed loved her, your father. But he was using her

I grabbed the can. "You know anyone at this party?" Anna asked. "Well, I'm Ryder's stepsister, you guys know him?" Esther and Anna broke out in laughter almost immediately. "Girl, everyone on the island knows Ryder Jake Williams. That's who you're talking about right? RJ?" Esther said. "Yeah, that's him," "Well, your stepbrother is a fucking legend," she laughed. The two girls then caught me up with stories about the famous RJ and his numerous sexcapades, and also a little bit about him being a promising young pro-surfer. But his latter achievement was greatly overshadowed by his first one.

Jake called out, his voice sounding muffled right against my wet skin, before he went right back to sucking me fast and hard. "Cool, hurry up you guys, break's almost over," the coworker said, his footsteps moving away until the door shut tight. The moment we were alone, I lost all control. The fear of getting caught mixed with the crazy pleasure pushed me right over the edge. "Fuck, Jake, I'm gonna cum—ahh!" I groaned loudly, bucking my hips as my release exploded right into his mouth. "Mmm, fuck yes, give it all to me, Jay," Jake hummed dirty, sucking hard through my release and swallowing every single drop until my knees went weak.

It made him look… human. Warm. Without realizing it, Emma smiled too. Across the room, a pair of eyes watched them closely. Damien’s cousin, Victor Blackwood, leaned against a marble pillar with a glass of champagne. “So…” He smirked. “The new Mrs. Blackwood has everyone wrapped around her finger already.” Beside him stood his sister, Vanessa Blackwood. “I don’t trust her.” Victor’s gaze remained fixed on Emma. “Neither do I.” Back on the dance floor, soft music began to play.

Then the thick head of his cock glides over my clit, teasing. “Confess,” he demands. “Tell me you’ve been fantasizing about your stepbrother’s cock.” “I have,” I gasp. “I’ve wanted it for years.” He drives into me in one brutal thrust. I cry out at the sudden stretch. He’s so thick, filling me so deeply with my hands trapped behind me. Gripping the chain between the cuffs like a handle, he starts fucking me just as I imagined. “Fuck, little sister... you’re soaking your brother’s cock,” he groans. “So tight. So fucking guilty.”

Lust would’ve been satisfied with any warm body, but none of them come close. I keep telling myself that’s all it is, though. That it’s just wanting what I shouldn’t want, just the thrill of it being forbidden. But then I picture her laughing at Ethan’s jokes, or looking at him the way she looks at me when she thinks I’m not paying attention, and my hands clench. Wrong, I remind myself. She’s my stepsister now. That line isn’t just blurry it’s carved in stone, but knowing that doesn’t stop the craving.

SERENA My eyes met with his, they were cold and emotionless. Unlike me, he showed no hint of surprise or shock to see me. It made no sense to me. How did I end up having sex with my stepbrother? Why has fate decided to turn on me this way? First, I lost my mate to my step-sister and secondly, I lost my virginity to my step-brother. "Who would have thought the Alpha would be this hot? For someone that came out of your stepmother, he is a sight to behold," Stella remarked as she stared lustfully at my stepbrother.
