For years, I've watched her—my stepsister, no blood between us, just the thin thread of our parents' marriage—turn into pure, aching temptation. At nineteen, she's home from college for the summer, her tight little body, those full t**s, and that fertile sway of her hips driving me f*****g insane. She's off-limits. Too young. Too innocent. My responsibility. But the second she sasses me, pushing those perfect curves against me with a smirk, something primal breaks. I pin her down, rip away every barrier, and confess the truth. One savage thrust, and she's mine—screaming my name, clenching tight around me. She fights the guilt at first, ashamed of how soaked she gets for her stepbrother's obsession. But soon she's on her knees in my room, begging for more, spreading wide on the kitchen table while I fill her again and again. I'll keep her locked in our twisted paradise, f*****g her through every stage, breeding her over and over until the world knows she's mine. No one else will ever touch what's mine. Warning: This is dark, explicit taboo erotica with heavy breeding kink, forbidden heat, age gap tension, obsession, rough dominance, impregnation fantasy, and unfiltered filth. 18+ only.
