The Magical Corset by Brian (Archive Link)
Really fantastic corsetry story that was posted on davepotter77’s WordPress blog.
The story is written from the perspective of a corset / gown shop owner, who recently has managed to create quite the special corset. As one of his new customers gets interested in different kinds of corsets, he decides to show his magical corset he created. It turns out the corset can do a lot more than just compress the wearers waist, and its new wearer gets more and more into it.
