Mandy Marx - He's Not Into Chastity

You've seldom seen me have so much fun, than in this playful scene with a boy who is desperate to earn MORE time in his bonds.
So, not into chastity at all, I lock a chastity device on, and I direct him to make himself cum. If he can, he gets extra dominatrix time.
He tries... so hard! And I give him a hitachi, but I have override control of the vibrator (he doesn't realize that). A "service orgasm" is what I call it. He gets frustrated as hell, my padlock jiggling immobilization stroke bitch. More mine by the minute, aren't you?
