Kneeling on a cold, hard floor, a man surrenders his most intimate parts to his demanding mistress. She secures his wrists and ankles, spreading his legs wide, exposing him completely to her. She demands he keep his eyes downcast, only raising them when she allows it. She runs a firm hand over his body, pinching and squeezing, marking him as hers. She takes her time, drawing out the anticipation, before finally attaching a custom-made chastity device, ensuring his pleasure is solely hers to control. She smiles, satisfied, as he struggles to adapt to his new, restrictive state.
