I found on gagged utopia site a story showing a strong influence from one of the best I've read here,
the Dice Game by A Pensive Pen (Alex Machin).
Link is:

There are three girls playing a game of poker to decide which of them will be transformed into a bondage f***toy for their sorority's benefit (the loser will be sold to several males). They raise the stakes, every one adding further torments for the unfortunate loser, every one hoping to avoid defeat.
The ending is a bit unsatisfying but I liked it, so if you're curious check it out.
(and I seize the opportunity to wish you all a Happy New Year).
