A stern mistress, clad in leather, takes command as her bound submissive, a willing lesbian, awaits her pleasure. The domina, a dominant force, begins with a firm grip, her fist disappearing into her sub's wet, welcoming pussy. She works her way deeper, stretching her sub's tight walls, as the bound woman moans in ecstasy. The mistress, a pro at her craft, alternates between fisting and teasing with a machine, keeping her sub on the edge of climax.
