Foot cuck cleans my sweaty socks

I'm back from a nice workout! Lately I've been wearing my socks for several days in a row while I'm exercising. This is to develop an interesting sensory experience for my foot slave, who gets the pleasure of sucking out all of the filth and moisture from my socks. I am harsh as I humiliate my sock cuck, continuously belittling and tearing down my slave's withering ego as he sucks on my sweaty toes like they're a big fat cock. I can't stop laughing at how pathetic he is for getting into this position in life. I really can't help it, being mean to him is so fun. He deserves humiliation. He tries to protest that I should change my socks daily, but there is no reason for me to do that when I have a slave to suck the sweat out for me.
