Stories that are the core of eproctophilia, which if you don't know is the fetish of flatulence (or farting as it were but you already knew that....don't you?). Some of these stories are mostly, if not entirely, erotic and might contain things of its nature, like mild sexual themes or nudity or the like. So be cautious delving into this group. You might just get a boner from reading this description because these are so erotic. Although I highly doubt it.
