Making Babies

I was shocked to find out my quiet brother was the neighborhood Romeo. How did I find out it was easy, woman after woman got pregnant and named my brother as the father of their child. Three women claimed he was the father and DNA tests proved he was the father; also, other women had also been sleeping with him. None of the pregnant women wanted to stop seeing him. That was 5 years ago and luckily for my brother he has a great paying job and a large trust fund to support his growing family. Now with 7 children and still seeing several extra women at the same time. His children's mothers and the children live with him, and he hasn't married anyone and says he won't ever marry. How he keeps everyone happy has me bewildered.
