She is my girlfriend but when I glance back again…Stephen’s gaze flicks to where her hand is resting against my arm. Something shifts in his expression. It’s quick. Almost gone before I can fully catch it but it’s there. And it hits harder than it should. By the time we reach my place, my head is a mess. “Text me later?” Lilian says, smiling softly. “Yeah,” I replied. She leans in, pressing a quick kiss to my lips but I do not feel that spark I felt when I kissed Stephen. “Get some sleep,” she adds before pulling away. “I will.”

“Before I do something stupid.” “That sounds wise,” Vincent said. But as I took my first two steps toward the door, the world tilted. My legs wobbled, the balcony seeming to sway beneath me, and I staggered forward, a gasp escaping my lips as I pitched toward the floor. Strong arms caught me, pulling me close before I could fall. “Easy,” he said quietly. Vincent's grip was steady, his body pressing against mine in the sudden rescue. I looked up, our faces inches apart, and time stretched. His breath mingled with mine, warm and laced with the faint tang of champagne. I could feel the rapid thump of his heartbeat against my chest, mirroring the wild rhythm of my own.

She blinked her eyes open, her mind racing to piece together fragments of what had happened. The soft touch of Julian's hands, the intensity in his eyes, the way she had surrendered to him completely. It was both intoxicating and terrifying. She sat up slowly, the blanket sliding off her bare shoulders, revealing the skin still warm from his touch. For a brief, fleeting moment, the memory of their forbidden encounter sent a pulse of heat through her. But the thrill was quickly overshadowed by the reality of their situation. The whispered warnings, the weight of their secrets, pressed heavily on her chest. He is his step brother .

And why does the thought of my stepsister under me make my blood run hot? The realization that the tension I had been feeling around her for months in end and the constant need to push her buttons and all wasn’t just about breaking her. I wanted her. I wanted to screw Annalise so badly. I might have before. But now, she was my stepsister. Still, it mightn't matter. We weren't related. I knew that. Our parents might have signed a piece of paper at court, but that was the whole of it. There was no drop of blood in this equation.

I cursed discarding the thing to the floor and erupting from the couch, then walked to the wine cabinet and pulled out a fresh bottle. “Bruh, what crawled up your ass and died? You’ve been absent-minded the entire time you've sat there.” Romeo asked walking to where I was and clamped my shoulder tightly, “Is everything alright? You’ve never been this distracted.” No. Not even a single thing is alright because that damn boy I have been working hard to get off my mind sprung back from wherever he disappeared to and guess what, he is my fuckin’ stepbrother. “I’m fine.” I snapped instead, then walked back to the couch and plopped myself.

To see us as brothers and sisters but the harder in the future they become. All of my good girl moral vanishes when it comes to my stepbrother, Ryder Saint. When it comes to him my thoughts were more than just the girlish fantasies of an inexperienced women were downright sinful. I cannot simply stop myself from wanting to have him.

RUSLAN’S POV Did I just kiss my step-sister? Yes. Was I in the right state of mind? No, I certainly wasn't. Hell, she is ten years younger than me, yet, I almost bend her over my office desk and fuck her to oblivion. Ivana Alex is my step-sister, even if we weren't related by blood, but that didn't stop me from cupping her soft boobs, fondling with her ass cheeks, kissing and fisting on her lips like a goddamn feast.

It read: I cannot wait to have your lips on mine again. The words, albeit not unsavory in nature, made her feel like there was only chemistry tying them down… And though that might be true, as a woman she couldn’t help but long for something more. She wanted to explore this passion which seemed to course through her veins, but also feared the consequences of getting together with her stepbrother – there was bound to be some kind of backlash, and she wasn’t sure she was ready for it. The next evening, came another text which said: You are driving me mad, and you don’t even care.

Not again. She was married after all, and he was just her stepbrother.
