The Divine Messenger of the Dragon Gods Wants to Have Some Fun

The last and most powerful of the dragon gods (who just happens to be very short and very stacked) spends her time sealed in a temple to prevent her powers from destroying the world. She's bored out of her mind though, so her guards send an orphan to keep company.

They start with board games, but it's not long before they start playing another kind of game. You guessed it, the one involving her gigantic boobs.
