Roman Charity 2: Four More Tales of Erotic Lactation is up for sale at all the usual sites. (Look, if I have to explain why I named it Roman Charity, you really aren't much of a fan of the erotic lactation genre. Just google it, okay?)
Yeah, it's a compliation of previously published stories, but you get a nice little price break...if you haven't already purchased them already.
