Tsunade!!! With her big breasts she can just taunt them!!! I mean who can't resist her overly large breasts? LOL
Heres a joke that I got from a friend but turned it into a naruto version
Kakashi comes in to Tsunades room where she is sitting and Kakashi asked, "What Mission am I going to be assigned on next?" (as leans forwards to talk to her) *Kakashi's elbow accidently knocks into her breasts*
Sorry Hokage My Elbow Touched Your Breasts. But if your heart was as soft as your breasts you would find it in your heart to forgive me. Tsunade leans in to whisper into kakashi's ear. "If your elbow is as hard as your dick...meet me here in an hour. LOL
