When a female companion sticks any appendage or foreign object into a man's butthole when he's not expecting it. When he decides he likes it and does not run out of the room screaming, it is then referred to as a, "Sunday School Teacher"
Keith had a crazy night last night he was making out with this sunday school teacher and she reached around and gave him a Sunday School Teacher, he felt weird at first, but then decided he liked it so he let her continue to violate him. In the morning she kicked his sore ass out because she had to teach Sunday School, but she called him in the cab to ask if he had a good time...he blushed and said, "Yes".

When you and a partner mutually masterbate while looking each other in the eye. Be careful not to touch one another as this will no longer be the act of Sunday schooling.
Me and Carlie we're Sunday schooling last night at her house. You could say it's getting serious.
