God must have given you quite a gift of teaching and then He gave you a great first time to show you that you have this gift. What an excellent experience. You never know how God is going to use you until you do something away from your comfort zone(like volunteer to teach Sunday School). I had a few teachers when I was a kid who were exceptional, but one in particular comes to mind. He taught American Literature and every day I would be excited to be sitting in his class. We read "Lord of the Flies", "Catcher In The Rye", "A Farewell To Arms", and "Fahrenheit 451", and he made all of these books just come to life in his lectures. I have always been a reader, so it was no problem for me to read any of these books, but we had some kids in the class, some jocks and party-types, who probably seldom sat down to read a novel. And even those kids loved the class and did very well in it. I think some people are truly gifted to be able to teach and it was cool to read your story.
