Sebastian,
I did a search and came up with this:
www.similarsites.com/.../schoolgirlspankingstories...39 Best Websites that are similar to Schoolgirlspankingstories.thumblogger.com - SCHOOLGIRL SPANKING STORIES - thumblogger.com
So it looks like it's no longer available. I didn't click on the url since it didn't have firefox's vote of approval with a green WOT (Web Of Trust) donut. However, if you're interested in looking into it, it may have some related sites that are truly similar.
