When the rest of the family was sound asleep, my wife’s brother quietly entered her bedroom and woke her up for sex. She knew what he wanted because they had been committing ince*st for years as teenagers and it was time for another round of “playing doctor”. That was the term they used for unprotected sex because their intimacy began long before they reached puberty. They explored each other’s bodies as chil*dren by playing doctor to see the physical difference between girls and boys. It all began with innocent curiosity and evolved into a sexual liaison that still happens on occasion.
