Heh, she must have been really blue-balled (or whatever alternative phrase is more appropiate for females) to be driven to orgasmic bliss from a mere mouth-to-mouth kiss.
I mean, her regular clothes are pretty much just a microdress that's practically guaranteed not to have any underwear below it.
Well, it's more that it really says something about her character if it's essentially 20% of the comic up until this point that she's not bothered to wear anything down there or hide it at all, and nobody even blinks at it. (To go back to the cameo with her sister in it, she's mildly impressed that lewd!elf even bothered to wear clothes at all.)
