I finally found a solution for slaves trying to squirm away from my heels and feet. I have separated his balls with a blue rope an pulled them tight over a small table. This keeps his cock and balls firmly in place while I tease and trample them endlessly with my feet clad in blue pantyhose. The more he struggles the more it hurts him - how delicious. After giving him, a footjob without end, I am so generous as to let him let him cum all over my beautiful feet. He is really making advances in becoming my subservient foot slave.
