Katarina goes walking, jumping, bending and jogging in a tight top. But not so tight that her big boobs don’t fall out! In the upgraded HD video, energetic Katarina comes out to train on the lawn to work-out her tits. Then she uses a battery operated muscle stimulator. She asks the photographer if he has any extra batteries on him, just in case she wants to keep exercising after he stops taking pictures. You have to wake up pretty early in the morning to keep up with Katarina.
