Hentai Shounen: Jun no Koufuku na Hibi

I enjoyed this manga but only because I'm a sick pervert and it contained a lot of that nature. Now I didn't thoroughly study this manga but as far as I know the main character is Jun and he looks fairly different from chapter to chapter because the time line jumps a lot. He is an incredibly perverted person and basically gets off to pretty well anything that has to do with sex or pain. This manga is just a bible full of stories of him well... being him... really fucked up. It's awesome. 8
