Sitting on the couch with her boyfriend Kassy gets more comfortable accidentally hitting her boyfriends balls with her feet. She notices him moan so she tries again. Laughing that he has some kind of ball busting fetish she punches him there to be sure. Now she knows how to control him and puts him on the floor so she can do this some more. She then realizes he also has a foot fetish and indulges in his fetish further by having him kiss her feet. She completely owns him now.
