Sasuke could have always donated his skirt-wrap thing, if he was too stingy to give Naruto his pants. XD; I think it's Sasuke that wants to see Naruto more naked, since he's refusing him a pretty vital piece of clothing. What a jerk. XD
I really love the way you drew the back of Sasuke's head for some reason. I keep looking at it going... "huh... ♥" Maybe it has something to do with the smirk right below it? You're also my hero for being well acquainted with the musculature of the human body. Not enough people pay attention to it (myself included). Thumbs up for anatomy!
In conclusion: Poor Naruto, mmm Sakura and Sasuke.
