Having noticed a recent new story achieving full-thumb status in a relatively short amount of time, this week I crunched some numbers and collected a set of “fast-thumb” stories that achieved 4.5-average star ratings at 5+ votes with above-average rapidity. (I may add a badge for this achievement at some point.) Hope there's something you like below, or you can browse the archives where thousands of smutty stories await.
The next weekly site update is tomorrow, 31 May. In the meantime, have fun exploring, and thanks for visiting the site.
