Stepbrother's Breeding Claim: Enemies-to-Lovers Descent into Breeding Addiction - Demi Muse

When nineteen-year-old Lily moves into the modern mansion owned by her twenty-four-year-old stepbrother Ethan, she expects tension from their newly blended family. She does not expect the dark, consuming hunger in his gaze or the way his dominance slowly dismantles every boundary she tries to keep. What begins as sharp words and stolen glances quickly ignites into something far more dangerous—an obsession that demands her body, her surrender, and the seed he refuses to let her lose. Trapped under the same roof with parents often unaware, Lily finds herself caught between resistance and an addiction she cannot name. Ethan claims her in secret, in risk, and in ritual, filling her until she leaks and then pushing every drop back inside while growling that she belongs to him now. As their encounters grow more frequent and reckless, Lily’s fight crumbles into desperate need. She craves the stretch, the warmth, the possession.
