Is this a 'come on in, what are you waiting for?' look, or a 'you peeped, now you're going to die' look?

Hmm ... looks mostly cheerful to me. I think there'd be multiple signs of anger, and possibly fire, if she was about to kill you. So, it's a "come on in, what're you waiting for?" look.

I always wondered on this one myself.

Though it's said Mokou can go from friendly to mean in a second, so who knows...

I'd say it's more like a 'Heh! I knew you're a pervert! Wanna play?' look :D

I've shown this to others, asking for opinons; one person has suggested that it's along the lines of "Ara ara, what have we here? A peeping tom? Oh, are *you* ever in trouble....but first, perhaps I'll have some *fun*....!"

Someone else said it seemed like an "All right, I'm gonna get laid!" grin. That or "You fell into my hot spring trap, and now I have an excuse to torture you!" / "All those who see me nude must be punished!" "But you're the one who took off your clothes..." "Shut up and bend over."

Also, isn't that a faint blush?

Looks friendly to me. Maybe also proud--"Look, I shaved!"

"Yo! I'm gettin' in!
Ah, don't go runnin' out on my account! 's not like I got the women's bath and the men's bath confused or anything.
You were a big help today, so I thought I'd wash your back a bit, is all.
That's fine, right? C'mon, it ain't like we're strangers or nothin'. My body ain't interestin' enough to make your dick stand, either, so... ah... It did stand...
Ummm... That, uh... Okay, I see... You did get aroused after all, didn't you... *blush*"

Thank you sgcdonmai this made my day

...Moukou, was your dad the only man you've ever been around?

Seriously?

That is what it says, if that's what you're asking. No joke.

I'm thinking.... "Ta-dah!! Hot spring!"

Take responsibility!
