(NSFW?) Can you give me a mock session of how you would tell a child where babies come from?

Mine would be:
When a man and a woman love eachother VERY much (Or just enjoy the way the other looks…) they go into their bedroom (Or the bathroom of the K-Mart…) and they take off all their clothes, like they’re going to take a bath… But they don’t take a bath. O.o
Then they get under the covers, like they’re going to take a nap… But they don’t take a nap. O.o
Then, this man, and this woman, do a SPECIAL hug. And nine months later, mistakes like you pop out. :)
