Summary
Four digits. Reaching my 1000th fic is a big milestone, so I want to highlight what I like to write in the countdown to that big 1000th with a little retrospective before each story, while revisiting some of my favorite themes. Most of these could've counted as regular stories, but the timing makes them extra-special.

Summary
This is a story of a world much like ours except for one major difference. The standards of what is and isn't acceptable to show in the movies and on TV are very different. As a result, sex and nudity run rampant on the big and small screen.
So sit down and enjoy an episode of one of Japan's top game show's, Aya-chan's Pussy Challenge. A show where five women from across Japan compete to show their strength and sexiness.
