When these sisters go out, they enjoy themselves. They have spent a whole day shopping and dancing. Their feet hurt and are full of funk. When they get home, they fully expect to relax. They call their slaves to them and have them sniff their feet. They enjoy the feeling of hot breathe on their feet, relaxing their muscles. When they take their socks off, they enjoy having their feet licked and toes sucked. This is what relaxation feels like for them.
