My Stepbrother's Leash: A Dark Taboo BDSM Stepbrother Romance - Blackmail, Breeding, Power Flip, and Forbidden Obsession

By Probably Fine Publishing

Collared. Leashed. Owned. Or so he thought.

Cassian Draven blackmailed his quiet stepsister into thirty days of total submission. He thought he'd finally break the girl living under his roof.

He never expected to discover she's secretly Mistress Vesper, the city's most ruthless dominatrix.

Cruel punishment explodes into a savage battle of power and obsession. The harder he tries to make her yield, the more she makes the untouchable king beg.

In this house, the leash goes both ways, and neither of them is letting go.
