My Forbidden Husband I kissed my father’s best friend. It was reckless. Disastrous. And worst of all—he hated it. Damien Luca is eighteen years older, untouchable, and every kind of wrong for me. A man carved from power, wealth, and sin—the kind of man who owns half the world and intimidates the rest of it. I told myself I’d let him go. That the crush, the obsession, the pull between us was over. But fate laughs at me—because now, I’m his wife. A marriage neither of us wanted. A vow neither of us can escape. And a fire we’re both trying—and failing—to resist. He’s forbidden. I’m off-limits. But we can’t stop reaching for the one thing we’re not supposed to touch.

I'd had a crush on my brother's best friend, Ethan—the most powerful Alpha of our Northern Territory—since I was twelve years old. When I was fifteen, I boldly confessed my feelings to him. He laughed and patted my head, casually promising, "When you turn eighteen and shift, if you're my mate, I'll mark you." That offhand promise became my greatest hope for three years. I spent every day waiting for my wolf to awaken, praying to the Moon Goddess that she would designate us as mates. But on the night of my eighteenth birthday, after my wolf first awakened, I was shocked to discover that Ethan truly was my mate! Ignoring the intense shifting pain coursing through my body, I immediately shifted into my wolf form and ran toward Ethan's training grounds. I clutched the gift I'd prepared long ago, but instead heard Ethan urgently confessing to his Omega assistant Victoria: "Who would be stupid enough to actually care about a true mate? The bond between her and me is just the Moon Goddess's mistake. I only love you. I'll only mark you as my Luna." The words hit me like silver bullets to the chest. My wolf whimpered in pain, the mate bond burning like acid in my veins. I stood frozen behind the trees, watching the man I'd loved for six years dismiss our sacred connection as if it meant nothing. Later, Ethan introduced Victoria as his "fiancée." When Victoria demanded that I publicly bless their marking ceremony, Ethan remained completely indifferent to my humiliation. "Sylvia should give us her blessing," Victoria announced at the pack meeting, her voice sweet as poison. "After all, she's been like a little sister to Ethan all these years." Every wolf in the room could smell my distress. But Ethan said nothing, refusing to even look at me. When rogue wolves attacked our territory and I was surrounded, Ethan didn't hesitate to scoop up Victoria—who had only a tiny scratch on her finger—and carry her away to find the pack healer. He left me bleeding and alone, silver claws ha

Mistakes? I’ve made plenty. The biggest one? Falling head over heels for Brian Lockwood—my brother’s best friend and the captain of the school’s basketball team. For years, I lived in the shadow of my one wish: for him to see me as more than just Simon’s little sister. But how could he, with Lyla, his perfect girlfriend, glued to his side? Then everything changed. Lyla cheated, Brian’s heart shattered, and he was desperate for a distraction. That’s when he came to me with a deal—a no-strings-attached arrangement where we could give each other exactly what we wanted. I saw my chance. I thought I could make him fall in love with me. But I didn’t account for how messy things could get—how keeping it all a secret from Simon would twist everything. And when Brian crossed a line I couldn’t forgive, I knew it was time to let go of my high school crush. Fast forward three years. I’m over him. Or so I tell myself. Except now Brian’s back, no longer the heartbroken boy I knew but a leading basketball star with one goal: to win me over. I swore I wouldn’t fall for him again.

“Shh, little girl,” he growled, teeth catching my bottom lip. I fought the moan, but he circled my clit, my hips jerked helplessly against his hand. Then he pushed my panties aside and sank two thick fingers inside me. I soaked his palm, knees buckling as tremors wracked me. “That’s it, cum for me,” he whispered against my ear. I did. Waves crashed through me while he held me up, stroking gently, murmuring filthy praise that made it sweeter, deeper, more shattering than anything I’d ever felt with a woman. I’m a lesbian. I’ve always known it, claimed it shamelessly. I’ve mapped women’s bodies with my mouth, hands, loving every touch and gasp. My best friend’s tongue between my legs has made me come countless times.

So why does this man, her father, the one I should never want make me wetter with one stroke than she ever has?
