It's all fun and games at the The Fosters household -- for now. Lena teaches Stef about some Twerking 101 while preparing for their family camping trip, and needless to say, Stef likes what she sees. Thanks to AfterEllen there is this pretty amazing clip. Catch a sneak peak of next week’s twerk-tastic episode here. At least these two are having fun for a minute before all drama breaks loose!
