BBC Throne Training by Ramona Ruiz

Nancy, a restless wife, finds herself irresistibly drawn to Aldrin, a commanding presence who promises the intensity her devoted husband Travis cannot provide. What begins as a forbidden encounter evolves into BBC Throne Training, a ritual of absolute power exchange where Nancy claims her role as queen while Travis is bound beneath her in total surrender. 

As Nancy's hesitation gives way to intoxicating empowerment, she discovers a cruel delight in controlling every breath her husband takes. Travis's love twists into a masochistic need, his identity fracturing under waves of humiliation and desperate devotion. Aldrin orchestrates each session with precision, deepening their descent into psychological domination and erotic corruption until the boundaries of their once-ordinary marriage dissolve completely.
