The mistress has a sadistic streak, deriving satisfaction from tormenting her slave, particularly in the aftermath of his orgasm. Today, she's meticulously prepared him for this, securing him to a bench with ropes that restrict all movement—arms bound behind him, body tightly restrained, legs spread apart, and a gag muffling his mouth to stifle any loud outbursts. To maximize sensitivity on his cock head, she uses a specialized sleeve that limits stimulation to just the tip. His erect penis is also securely tied along with his balls to keep it rigid throughout. With her slave thus prepared, she begins her game of indulgence, employing a milking machine specifically designed for this purpose. However, instead of allowing him an immediate orgasm, she adopts a deliberate stop-and-go approach, prolonging the stimulation on his sensitive cock head. Then she decides to release him, allowing him to ejaculate into the machine. In this moment, she finds complete satisfaction, observing as the milking machine continues to stimulate his sensitive cock head post-orgasm, prolonging both her pleasure and his suffering—four minutes long.
