Step Siblings Sex Stories

My life was simple. Boring, even. That changed the day my mother married the richest Alpha in the pack. I fell for his son, my stepbrother Felix Dimitri is damn hot, infuriating, and impossible to ignore. He is my stepbrother by marriage, my fated mate by the Moon Goddess’s cruel design, and the one man I should never want. His storm-dark eyes ignite something inside me I cannot control. Every glance tightens the bond between us. Every accidental touch feels dangerous. I know he feels it too, even as we both pretend we can outrun fate. School, family, friendships. Nothing stays untouched when desire cuts this deep. Staying away from Felix is impossible. Giving in could destroy everything around us. But resisting him? That may be even harder.

"Look at the target, Gabe," Derek hissed, his voice a low vibration that settled in my bones. "Imagine it's my heart. Imagine you are finally putting me out of my misery." I was trapped between the cold metal of a gun and the burning heat of his body. My finger trembled on the trigger, but I couldn't pull it. My name is Gabriel. To the world I am the nerdy quiet university student. To Derek Miller, I am his toy. He found my secret sketchbook, page after page of his naked body drawn with obsessive detail. Now, he uses those sketches to keep me on a leash blackmailing me whenever he wants a taste of my dignity. But the nightmare was only beginning. When my religious mother announced she was marrying Derek’s billionaire father my world shattered. My bully wasn't just a ghost from campus anymore, he was my stepbrother. We share a room. We share a bathroom and now my body. He is everywhere I breathe. He claims me. He insults me. He treats me like trash. And the sickest part? I have realized I loved it rough. Our obsessive love is impossible. My mother would disown me, the Miller name would be tarnished, and Derek’s tough love is starting to leave scars I can't hide. Just as I am about to break, a new guy enters the picture someone who promises to love me softly. Someone who doesn't smell like gin and danger. But in the dark world of the Millers, safety is a lie. Now I have to choose: Do I run toward a peaceful future, or do I stay with the devil I already know?
