Joined a Family

I 24 married my sweetheart 23 at college; I'd intended to marry her. But it was brought forward when got pregnant. Both our families are well off, but my wife's family had no men left. Due to my wife's pregnancy, we lived with her mother 46 and aunt 48, both successful in their careers. After leaving college to start my career I joined the firm where my mother-in-law and her sister were partners. Of course there was favoritism, but not because I was the son-in-law. It was because I was the family dildo, regularly used but my wife, her mother and aunt. Very willing I must add, I really do like sex.
