A serf, collared and chained, stands trembling before his mistress. She runs a gloved hand over his body, pinching, twisting, and squeezing until he gasps. She commands him to lie back, then attaches a spreader bar, opening him wide. She teases his cock with her tongue, bringing him to the brink before stopping abruptly. She switches to a flogger, striking him in a rhythmic dance, marking his skin with red welts. As he cries out, she smiles, leaning in to whisper, "You will come only when I allow it."
