The plan was simple: move in with my mom, play the dutiful daughter, and count down the days until I could escape back to my real life. I didn’t expect my first night out to end in the parking lot being fucked by a silver fox who looked at me like I was his favorite sin. I thought it was a one-night mistake. A filthy, beautiful secret I’d take to my grave. Until the next morning, when I met my mom’s new husband... and he was him. Now, every family breakfast is a slow-motion panic attack. Every glance across the dinner table is a reminder of his hands on my skin. I can’t tell my mom the truth, but the deeper I sink into the Schmidt estate, the darker the truth becomes. Because in this house, there are no rules. There is no "mine" or "yours." There is only ours. I thought I was falling for a man. I didn’t realize I was being claimed by a bloodline. It turns out I don’t have a husband... I have masters. And they aren't finished sharing.

Her top was on the kitchen floor. His shirt was open. His hands were at her back. The rain was loud against the window and there was nothing left between them except the last three years and the breath neither of them was taking. Then headlights swept across the wall.

"Genie" His voice was barely a whisper, his breath warm against the shell of my ear. "This is so wrong, we can't be doing this." His lips find their way back to mine, trailing the bottom lip with his tongue. "So so wrong" He pulled my lower lips in, biting on them. I stifled a moan. "I know," I managed to say. I could feel the warm slickness ache between my legs. "We shouldn't be doing this. You're my step brother." My body doesn't agree with what my mouth is saying. I snuggled closer into his chest wanting to feel the heat of his bare body against mine. I want his mouth against mine, ravaging me like he had done before. We have gone too far to back out now. "Take me, Ryder" Those were the words he needed. Only those three words. Suddenly, he grips the back of my thighs and lifts me up, forcing my legs to wrap around him. Planting me against the wall, he peers up and look straight into my eyes "You're mine" Then his lips came down on mine. I'm yours. I whispered back in the back of my head. ******** Ryder Saint, for years, has bullied me. Reasons? None. It was like he signed a contract from heaven to make my life hell. From the moment he set his eyes on me, he added my name to his list. Don't be fooled by his last name. It's a charade, he's not anything like it. Everything about Ryder Saint smells evil. His heart, dark. His soul, dark. His aura, dark. Except his face. I should have neglected him like I always have, but I couldn't when our parents decided to tie the knots and he became my stepbrother. He and I, under the same roof.

"Don’t worry, Sister," Lorenzo says. "Our dirty little secret is safe with me. Infact, it is already forgotten. It wasn't even that memorable. Just a few lousy sex." I gape at him, not wanting to believe the words coming out of his mouth. This isn't the Lorenzo I knew. It's like he changed to this cruel bastard standing in front of me. What happens next is out of character. It's like someone takes over my body and controls me. I don't even think about it, I just act. The slap I give to him across his face lands with a crack that draws the attention of passersby who murmur and point at us as they pass away, probably wondering who the crazy bitch is. I back away from Lorenzo in horror, my now throbbing palm held in my other hand like I just touched a hot pan. Lorenzo brings a hand to his cheek which is now spotting an angry red color and stares at me in shock then he laughs, the sound bitter and cutting through the still night's air. "When did Little Miss perfect get feisty?" He drops his hands and eyes me, a leering look in his eyes. "Maybe I shouldn't have been so quick to dump you." He rubs his jaws, still eying me. "Who knows, you might have brought this attitude to bed. It would have definitely made things more exciting." I hate him so much.
