Understanding something isn't the same as having it all translated into English and ready for typing into translation notes, and frankly I don't care about this image enough to translate it. Maybe someone else will.
Ah...do you seriously want to smell my feet?
That's so creepy...
They're filthy, and...
Well...you really wouldn't want to bring your nose too close.My feet are sweating horribly...and stink terribly...and yet you find that pleasant?Uh...
There's not enough water around, and...
I-I haven't washed them in forever, so...
Um......they stink...Not to mention, don't you know how bad it is to act so familiar with a stranger?!Umm...okay...
If that's really all...
It should be alright...Huh? You wanna lick it?A little licking...is fine too...I guess...So, what you're really saying is...Ugh...Onii-san, are you a pervert...?
Gross......ummmmm...if it's...only...my foot......You really just want to sniff my foot, that's all?
