Virgin Stepsister's Blushing First-Time Craving

I never thought my life would turn into one of those steamy confessions you whisper to yourself in the dark, but here I am, spilling it all out like the dirty little secret it is. My name's Lily, and I'm 18, a shy virgin who's been hiding the biggest craving of my life from everyone—especially my stepbrother, Alex. Our parents got remarried a year ago, blending our families in this big house on the suburbs' edge, and suddenly there he was: 20 years old, confident, with that chiseled jaw, messy dark hair, and a body from hours at the gym. He's the kind of guy who walks around shirtless after a shower, towel slung low on his hips, making my cheeks burn and my untouched pussy throb with need.

I'd never even kissed a boy before him—not really. High school was a blur of books and blushes, too timid to flirt. But Alex? God, he invaded my thoughts. Late at night, I'd lock my door, slip my hand into my panties, and imagine him pinning me down, his strong hands everywhere. I poured it all into my diary, the pink leather one hidden under my mattress. Pages filled with filthy fantasies: "I want Alex to be my first. I want his thick cock stretching my virgin pussy, popping my cherry while I beg for more. He's my stepbrother, but that makes it hotter—taboo, wrong, perfect."

I never meant for him to find it. But one afternoon, while I was at my part-time library job, he was rummaging in my room for a charger—nosy as always—and there it was, flipped open on the floor where I'd been careless. He read every word. My heart stopped when I got home and saw him sitting on my bed, diary in hand, his blue eyes dark with something dangerous.

"Lily," he said, voice low and rough, holding it up. My face flamed hotter than hell. I wanted to die, snatch it away, but my nipples hardened under my thin tank top, betraying me. "This... you really wrote this about me?"
