My quiet uncle

My uncle David was always very quiet hardly spoke and didn't seem to be in any relationship. So, I was very shocked when my mother said David her younger brother was expecting children. Twins I asked, no three children from three different women. My uncle had gotten two sisters and their cousin all pregnant and they were living together like they were married. He was 12 years older than the older of the women and 15 years older than the youngest. I was then totally blown away when I first saw the women, I'd expected plain Jane types, and they were gorgeous. My uncle isn't what I would call handsome, just average in looks and build. He must have some hidden talent I don't know of as yet.
