I have teased my slave relentlessly for almost an hour I allow him to cum. But I cannot resist the urge to extract every last drop and beyond using a stretchy tube over a hitachi wand. He is chained up from the ceiling at his wrists and waist so there is no getting away. He suffers as I continue to use the hitachi wand and tight tube on his sensitive cock. I say "it would be a shame if we didn't get every last drop" and if that isn't the worst, ha ha. I leave him chained up while I go and lay on the bed and use the hitachi on myself!
