Unexpected Present

Unexpected Present is a romantic femdom story. It begins on Christmas Eve with a young married couple, Paul and Kate, who are in a vanilla relationship. They are in love, but Kate has secretly wanted to add BDSM elements to their sex life, with her as the dominant. While Paul is not an active submissive, he likes that Kate often initiates sex, and he has had occasional fantasies about being helplessly teased by a beautiful woman.
They have decided to exchange symbolic gifts over the Twelve Days of Christmas. The theme of Kate's gifts is that she wants to add femdom elements to their relationship. Finding what he thought was the perfect present, however, had driven the agreement out of Paul's mind until the last minute. He scrambles to put together twelve presents, and fatefully decides to give her a chastity cage he had bought on an impulse, as her first gift, and the keys to the lock as the second.
This sets a pattern, and after they exchange the first two gifts, Kate interprets every gift as symbolizing Paul's desire to submit to her. Because he loves her and doesn't want to disappoint her, and because he doesn't want to admit he has no theme for his gifts, Paul does not correct her assumptions.
With each day, they go deeper. The chastity cage and keys lead naturally to teasing and denial. They move quickly on from there to spanking, bondage, discipline, financial control, and on New Year's Day, Paul agrees to become Kate's slave for a trial period.
As day by day Kate becomes more dominant, they find their feelings for each other growing stronger. Kate is deeply moved by the trust he shows in her, and being able to engage in the dominance she had only fantasized about before makes her love him more. Paul knows that she would understand if he told her he forgot their agreement, but he doesn't want to hurt her. He also finds the new, more dominant Kate, sexier and more exciting. And by New Years, he is disturbed by how naturally he submits to her. Is Kate's unexpected present going to vanish before the 12th day is over? Or is it a present that will last a lifetime?.
