Penny Birch 
Pony Girl Collection [EPUB ebook] 

Pony-girls is a collection of three classic erotic novels, all on the same theme and from the pen of Penny Birch, who is not only one of the most imaginative writers in her genre but has first-hand experience as a pony-girl. A Taste of Amber, Penny in Harness and Tie & Tease are all drawn from that experience and combine a true feast of fetish erotica, with not only the most vivid and realistic descriptions of pony-girl play ever written.
