Stepbrother's Forbidden Midnight Craving

I couldn't sleep. Again. The summer heat clung to my skin like a second layer, turning my sheets into a sticky trap in my childhood bedroom. At twenty-two, home from college for break, I should have been exhausted from unpacking and dodging my parents' endless questions about my major. But insomnia had me by the throat, same as always. It was past midnight, the house dead quiet except for the distant hum of the AC. My stepbrother Jake's room was just down the hall—had been since Dad married his mom five years ago. We'd grown up under the same roof, polite strangers turned awkward siblings, but those stolen glances over family dinners? They'd piled up like unspoken secrets.

Thirsty and restless, I slipped out of bed in my thin tank top and boy shorts, barefoot on the cool hardwood. The kitchen glowed faintly from the nightlight above the stove. I froze in the doorway. There he was—Jake, twenty-four, shirtless and poured into gray sweatpants that hung low on his hips. His muscular frame, honed from years as a gym trainer, gleamed under the dim light, broad shoulders tapering to that V of abs I pretended not to notice. And fuck, the outline in his sweats—thick, hard, straining against the fabric like it had a mind of its own. He was rummaging in the fridge, oblivious, a glass of water in one hand.

Our eyes locked when he turned. Heat flooded my cheeks, but I didn't look away. Neither did he. Those lingering glances from years back—the way he'd watch me stretch in yoga pants during family movie nights, or how I'd catch myself staring at his biceps when he lifted weights in the garage—ignited something feral right there in the midnight hush. Stepsiblings under the same roof, yeah, but the tension? Forbidden as hell, crackling like static.

"Can't sleep?" His voice was low, gravelly, that gym-rat confidence laced with something darker.

"Insomnia's a bitch," I murmured, stepping closer, my heart hammering. The air between us thickened, heavy with years of what-ifs.

He set the glass down, not bothering to hide the bulge tenting his sweats. "Mia... fuck, you have no idea how many nights I've lain there thinking about you." The confession tumbled out, raw and unfiltered, his blue eyes burning into mine. "Ever since you came home this summer, seeing you in those tiny shorts... I've been hard for you non-stop. Suppressed it for years, but I crave you. Want to bury myself in that tight little body."

My breath hitched, thighs clenching. God, I'd fantasized about him too—late-night sessions with my vibrator, imagining his strong hands pinning me down, that thick cock splitting me open. "Jake... me too. Every time I see you without a shirt, I picture you fucking me senseless. It's wrong, but I can't stop."
