I have read this story, but it was in another site. Why don't you post the next chapter?

xD I really can't imagine Sasuke's expression when Tsunade said spanking

boring

NAY!

..but don't get me wrong or nothin',i still liked ur story a lot. ^^

OMG xD That's hilarious! I loved Tsunade's expression at the end! :P This is totally awesome; Sasuke getting spanked? Totally original idea, nice work!
Lol I liked this part:
He was going to train or someone was going to die – he had no idea who, but he was feeling up to smashing in the face of just about anyone who looked at him funny and the ANBU seemed like they might be a good place to start.

POOR SASUKE!
That was so funny! lol
This was nice, very nice.
You should do another one of these, perhaps one with Sakura.
