Slave has already been milked once, and I'm feeling generous enough to unlock his chastity device before continuing to drain his balls. I put him on his back, hooded, and tie his legs back allowing me easy access to his ass, balls and cock. I stretch him open, tease and clamp his balls, and then use my gloved hands and a vibrator to milk him dry. I make sure to catch every drop in a glass, as I have plans for his cum later...
