Cyntia's Sin

Part of the series Dogging Tales, this book tells the story of two couples, John and Cyntia, and Terry and Susan, who find out about dogging, and decide to find out if it's for them. Before they do that though, Cyntia and Susan get together and experiment with girl-on-girl action for the first time, and after that the two couples try a foursome. The girls decide to spice it up a bit by using the internet to invite more random men along for their first try at dogging, and it all goes spectacularly right for them!
