Little Tara wants to help change her friend, an AB boy's diaper while their mommy is breast feeding him. Belle says OK as long as she is careful. Tara does a pretty good job wiping his willy clean except he starts to get a stiffy. Fascinated because she does not have a willy herself she rubs it up and down more and more until it is really stiff and hard. Her mommy chastises her for playing with his private parts. Tara also manages to spray powder everywhere
