Not sure what to really say about this particular piece, since as far as I know, the character above (simply known as "The Adventurer") was originally a human hero that found themselves transformed into a rather voluptuously pregnant dragoness, because apparently, ancient magical curses were just like that back then. =p
And as for the decision to show her in lingerie, well, wearing such garments tend to grant a "sexiness" bonus to one's Persuasion Skill when dealing with shopkeepers; and judging by her expression, she'll need every bonus she can get if she intends to successfully get a discount on health potions for her next dungeon crawl.

Also, D&D references for the win! Yay! :D
