Damn... sorry there hun! :D
Now I know you're a girl... how could i guess?! Post your name next time! LOL
Pricy? Well... not at all! Hentai content costs much more to produce hun... every image you see there has been sketched, then drawn on a paper with a fine pen, then scanned, then computer corrected and painted, then cropped and FINALLY it's ready. Repeat the recipe 30 times and you have a set!
If you take a look at other places that sell hentai content you will see that this is a great price for a serie!
Take care!
