Family discission

My extended family wanted to keep the family wealth within the family and so I was asked to marry my second cousin I'll call Jane 23. I'll call myself Jason 29, we're the last of the line so to speak. Others in the family are old with the youngest being 59 (female) and everything is concentrating towards me, and Jane's mother was my first cousin who passed away in a boating accident twelve years ago. I'm an only child due to being born when my parents were in their late thirties. Jane is good looking and had been raised on the family estate home schooled never been to a proper school or even travelled much at all. So, she is a very quiet woman and was easily convinced to marrying me by the family. I'm the complete opposite to Jane and had a few sexual partners over the years. Especially when attending university, but the girls I bedded weren't marriage material in my eyes. So, I was asked to marry Jane and she met every single criterion I had for a wife. But I had the view she would be boring, not as exciting as other women I had been with. My aunt told me it would be up to me to shape the wife Jane would become. So, we married, and I took Jane on a long honeymoon (3mths) travelling the world and teaching her to please me sexually and I realized if I was to succeed, I would need to please her as well. Which made our sexual relationship the best I've ever had. By the time our honeymoon was over Jane was pregnant, she got tested and nothing of concern was found. Now 23 years later we've 5 children all healthy and I'm quite happy with my agreement to marry Jane.
