Your pages have very few sales text and links to sponsors on them (an average of 1 link on each page).
Example 1: on the index of this page
http://www.sinnerscorner.com/freesit...le_submissive/ you've got 0 links to your sponsor, the index page is by far the most important sales page of your site because you have to try to get every surfer asap to your sponsor and the index page is the first opportunity to do so. Try to use your allowed 3 links per page to it's fullest potential on each page.
Example 2: on this page
http://www.sinnerscorner.com/freesit...es1/index.html you got 10 images wrapped around 1 simple banner. Again, try to add some more text (links) poinyting to your sponsor. The clickthrough ratio on that page will be very low as it is now.
