it can´t be done, if it´s a hentai you can wait if the video will become licensed, then there will be an uncensored version.
In case it´s a JAV - many of them are uncensored from the beginning, the others are only released censored, I´ve never heard of a censored JAV becoming uncensored in the end...
oh kk,ty.., ill dl and see ^^ i only have 80 kb/s dl speed so its kinda going slow,da downloading tht is.!!. o.o,and i kinda get disspointed when i see that hentai is censured -.-
