Princess Ivory - Locked Up

Ivory walks in on her boyfriend jerking off for the third time today.. She sits down at his feet and grabs onto his cock. Showing him the chastity cage, she begins to explain that he will be participating in Locktober. His cock will be under lock and key, the only one with access is her.
She puts him in the cage, explaining how this officially makes his dick her property. Being locked will keep him from wasting so much time tugging on his dick. He will be so much more productive and useful!
This is just the beginning. She likes the way it looks all locked up, and wearing the shiny keys around her neck. No Nut November is around the corner and he will be well prepared by the end of this month. Then, the possibilities are endless! He better take well to the training because this is just the beginning. This could even cause his dick to shrink from lack of use if he isn't careful. So he must devote his entire existence to pleasing her now, all with the hopes she will let him out.
