Cockbox Footjob and Foot Worship Training - Orgasm Control

No matter how good this feels, X is not allowed to cum. Foot X have to be very good and need to have control of their orgasms. My foot X is locked inside my cock box- Wrists cuffed and ankles tied. It keeps him nice and still so I can play with his cock as much as I want. Today is a training day for him. Having to sniff and smell my stinky toes while getting teased - All without cumming. He knows there are consequences for cumming, and rewards for doing what he is told. Lucky foot X also gets to suck my sweaty toes clean and gets gagged by my heel as my soft oiled foot keeps him on the edge.
