Book two is about how the best man and the maiden of honor have to make sure the bride and groom get up the next day in time to leave on their honeymoon. The bride and groom are passed out drunk, though, so they spend the night together in the honeymoon suite with the unconscious newlyweds and things get heated up.
In Book three the maiden of honor, a lifelong friend of the bride, flirts with the bride's father, a widower. Both have had naughty thoughts about the other over the years. Now they can explore those thoughts.
Book four describes how the entire bridal party gathers two days before the wedding at the mansion owned by the bride's father. Turns out the bride's family are nudists and the rest of the party is invited to join in. Groomsman number two and bridesmaid number two are told to get to know each other.
