Fawn is really a weird word o.O
I have a question: Why in every manga has girl tears in her eyes even though there isn't a reason for her to cry (For example, Azu lickin' Yui's breasts)?
I dunno about anyone else, but I tear up at intense experiences as well as sad or emotional ones. Given the rather odd Japenese fetish for embarrassment, I can see those being combined in a case like this.
As always, I may be wrong.
