Selene is newly spayed, and is too young to have ever displayed sexual behavior. Charlie was neutered in October 2016, and never displayed sexual behavior before that. Today, in the span of a few minutes, he bit her neck and mounted her twice. I've read enough cat books to recognize that position.
They immediately went back to playing, but I admit to being disturbed.
