My thoughts are that what you describe is for lack of a better word, "normal" behavior for children that age and could very well have been a coincidence that your mother noticed it right after your visit with your aunt.
I have never, ever seen this in a two-year-old. It's normal for a two-year-old boy to play with his penis, esp. when naked (sometimes alarmingly -- boy, do those things stretch) and sometimes you'll see a toddler girl feeling around her vagina. But this dry-humping thing, no, in years of spending hours daily with small children, I never saw that.
