Katara looks for something to get her feet dirty. She found a mud puddle near their spot. As she dips her foot one by one on the puddle, Naruto stares in disbelief. He didn't know that this girl would go far. Katara turns back to Naruto and said,"I want you to clean my feet with your tongue. Make sure it's spotless, and go between the toes, too." Naruto immediately started licking Katara's left muddy feet.
Katara was enjoying getting her feet clean, while Naruto suffers and chokes from the mud he swallows.
After 20 minutes, Naruto was done removing the dirt from Katara's feet. Katara examined it and looked back to Naruto with an evil smile. She dipped her foot again in the muddy puddle. Katara said,"Not good enough....I want you to do it again!!"
Naruto whined,"Huh?"
Katara laughed and responded,"That's right!! You'll do it again.....and again....and again until its completely clean. Now start licking, boy!!"
