The sub, trussed up and vulnerable, is at the mercy of their dominant master. The master, a sadist with a taste for the extreme, runs a gloved hand over the sub's body, their touch firm and authoritative. They pause at the sub's nipples, pinching and twisting, drawing a moan from their lips. The master smiles, reaching for a whip, "You know the rules, pet. Silence means pain." They crack the whip, the tip lashing across the sub's chest, leaving a thin red line. The master then picks up a large, phallic toy, "Now, let's see how you handle this, shall we?" They press it against the sub's entrance, pushing in slowly, watching as the sub struggles to maintain their silence.
