Fixed Permanent Chaste Slave Used as Vibrator Stand
Slave Ciphers is in trouble. Locked tightly in his chastity cage, he left a trail of lust juice on the floor in the morning. This displeases his mistress Lady Claire, who has classified him and his genes as useless permanent chastity slaves.
As punishment, she ties the slave firmly to the bed. His balls are tied up and exposed by the chastity cage and the rope, so that she can easily abuse them. She reminds the chaste slave how useless he and his cock are for a woman's pleasure. His balls are only there to make him controllable.
The sight of the helpless slave arouses Lady Claire and she spontaneously devises a plan to use the slave's urges against him. She sits down in front of the slave with her legs spread and orders him to lick her when he gets close. He whines because his balls are tied to the end of the bed. Nevertheless, he pulls on them in the hope of reaching his mistress and being allowed to lick her.
In the end, she attaches a vibrator to the slave's head as an extension with which he must bring his mistress to orgasm.
