Serena is instructing how to perform various yoga positions using her long legs and feet. She uses her assistant face on her feet in order to get good resistance with some of the positions. She also uses him to clean her feet. He tries to get away with just cleaning her feet with a towel, but she makes him use his tongue instead. We later see the 1st person view of Serena's soles while the assistant's face is right inside of her soles. This Clips4Sale Clip (
