She has a fantasy she wants to explore and has the means to do it. Joining a monthly sex club was never part of her big life plan, but the desire to explore that part of herself is too intense, the pull - too strong. The first month she goes, she meets a woman who is every bit her type, but flees. Each month she returns to find the same woman working the event to enjoy one night with her. One night per month is all she thinks she'll ever get. Only she finds herself wanting more than one night, wanting to know her name, learn about her life, see her outside of their arrangement. Should she risk it, or keep things just the way they are?

In Once a Month, there's a Member and an Escort. Each month, there are two sides to the story of their time together, and over the course of the year, they discover the fantasies they've not shared with others before. They also discover that this might be more than just fantasy.
