Step Cousin

I've a cousin who was adopted at the age of 1, he was always a quiet child growing up. But did very well at his schooling only one in our family to go to college. In 2020 his parents died of the virus, he was 20 going to college on a scholarship. With my aunt and uncle dead he stayed with us on his breaks from college as they had always rented. At 21 he was contacted by a large national law firm; he had been finally traced by his extended family. Not that there were many of them left. As the youngest and whose mother had him out of wedlock and had given him up for adoption. Only told her family of his existence on her death bed, hence the late search for him. His family very well to do and rich, who very happy to have found him. As our family had done a great job raising him, they took us in with him you could say. We were having a rough time at the time getting by given good paying jobs within the family business empire. We were fairly well setup for a better future, my step cousin and me were the closest in our family. Always been best friends no matter what, with his true family now paying his college tuition. He was moved to a top Ivy league college, but it was far away from the family as well as is found family. He would get nervous so far from family and friends. So, as I was his closest family member easily seen by our always hanging out together. I was sent with him, not to attend college, but to keep house for him as he was to live off campus. I'm a year younger than and more worldly than he was. He wasn't shy, just reserved my late uncle had always said. Over the course of us living together away from the family, we hung out together all the time he wasn't at the college. If he had to go to something, I when with him as his date you could say. I'm not gorgeous, but pretty is closer to the mark, my whole job was to support him. Over the time one thing led to another and we became lovers and in his final year of college I got pregnant. None of the combined families were shocked, as they thought we were always going to hook up as my father called it. A quick wedding family only was arranged and I again pregnant this time having a son, our daughter is the pride of the families, and our marriage is the best thing in our lives.
