For the Girls is my number one seller in this niche, but you might want to try
Pimp Roll's Couple's Pleasure Dome and Hetro Male Pornstars. They were both built by a woman, and do very well on my traffic for women.
Plus, if you have both men and women reading your stories, Couples Pleasure Dome will appeal to both. You will find links to them under the AVP sites in the Pimproll portfolio.
