The Reluctant Dom [EPUB ebook] 

When the pretty, though spiritually conflicted Cassandra approaches Charles in a Chicago suburb, both lives are changed forever. Plagued by a lifetime of repressed sexual desire, Cassandra allows Charles to fondle her breasts in public, and he becomes instantly smitten with her. Despite her religious beliefs and impending marriage to Patrick, she confesses her desire to enter into a submissive/slave relationship. Charles agrees to a fourday contract to become her Dominant. Reluctant at first, Charles grows more confident in his role, sexually dominating and disciplining Cassandra with increasing force. He buys her bondage toys, sheer sexy clothing and body jewelry, then displays her in public, later taking her to Obsessions, a Gentlemen’s Club catering to D/s couples. There she dives even deeper into her submissive desires. Their contract states that there’ll be no emotional involvement – or further contact between them once the four days are over. However, Charles has become emotionally attached to her. When the contract is up and Cassandra goes back to her fiancé, a devastated Charles risks one final attempt to draw her back to him.
