Bertha's guest tonight is a first-timer, their eyes wide with nervous excitement and a hint of fear. Bertha, an expert in breaking in new subs, starts with a feather-light touch, tracing patterns on their skin with a cat-o'-nine-tails. She watches their goosebumps rise, their breath hitch, before landing a sudden, sharp strike. They gasp, their body arching against the restraints. Bertha chuckles, "That's it, baby. Feel the pain, let it consume you." She alternates between gentle caresses and harsh strikes, pushing them to their limit. The submissive's cries fill the room, their body glistening with sweat, as Bertha brings them to the edge of ecstasy and back, over and over again.
