No matter how good this feels, slave is not allowed to cum. Foot slaves have to be very good and need to have control of their orgasms. My foot slave 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 slave also gets to suck my sweaty toes clean and gets gagged by my heel as my soft oiled foot keeps him on the edge.
