“You’re mine now, stepbrother. No one else gets to touch you like this.” Lucas Reed’s low growl still echoes in my ears. The arrogant basketball star and my new stepbrother pinned me against our bedroom wall and ruined me in ways I can’t forget. His hands, his mouth, the way he claimed every inch of my body while our parents were away… it was filthy, addictive, and so damn wrong. Now our parents are back, expecting the perfect blended family. But Lucas is obsessed. Jealous. Possessive. He sneaks into my bed at night and reminds me exactly who I belong to. And just when I thought things couldn’t get more dangerous, my obsessive ex Julian transfers to our school. He knows my secrets. He wants me back. And he’ll do anything to tear us apart. Every stolen kiss is riskier. Every secret fuck is hotter. One moan too loud could destroy our family forever. He’s my stepbrother. My biggest sin. And I’m falling helplessly for his forbidden touch. How long can we hide our dirty little secret before it burns everything down?

I’ve loved him for as long as I can remember. But he never saw me that way. His eyes were always on her—not me. And when he chose her over me, marrying the girl who had always been his world, my heart shattered in ways I never thought possible. Then I found him. The one who makes me laugh, who makes the pain of heartbreak fade… but there’s a problem. He’s forbidden. Older, untouchable, and the brother of the man I once loved. I told myself it wasn’t serious. That I could keep my heart guarded. But as our connection grows, the walls I built begin to crumble. Now, I’m caught in a dangerous, irresistible pull—one I shouldn’t give in to, but can’t resist. Some loves are forbidden. Some desires are dangerous. And some hearts, once broken, refuse to stay silent.

When Olivia moves into her father’s house, she expects discomfort and distance—not the quiet pull she feels toward his son. Adrian is older, already in college, and careful in ways that make him seem unreachable. At first, he treats her like a responsibility, someone he needs to look out for. But closeness has a way of changing things. It begins with small moments. Lingering conversations late into the night. Shared laughter that feels too intimate. The way Adrian always seems to notice when Olivia is overwhelmed, the way his voice softens when he speaks to her. What starts as protection slowly becomes attention—and attention turns into something dangerously close to desire. Olivia feels it first. A flutter in her chest when he enters the room. The way her breath catches when their eyes meet for a second too long. Adrian feels it too, even as he fights it—pulling away one moment, drawn back the next. They never say the words. They don’t have to. Every look holds meaning. Every accidental brush of hands lingers longer than it should. The air between them grows thick with everything they refuse to admit. They know the line they’re standing on. They know crossing it would change everything. Yet the heart doesn’t care about rules. What grows between them is soft but consuming—tender, aching, and forbidden. A love born in restraint, made stronger by everything they deny themselves. When their secret is discovered, it shatters them both. Adrian is sent away without goodbye. Olivia is left behind, clutching memories that feel too precious and too painful to keep. Years later, Olivia has built the life she once dreamed of. But some feelings don’t burn fast and disappear. They smolder. They wait. And they never truly let go.
