A mom and her 10-year-old daughter had a very open relationship. They'd talked about the birds and the bees and the mom had always told her daughter she could ask anything she wanted to know and not be ashamed or embarrassed.
One afternoon, mom and dad got frisky upstairs while their daughter was engrossed in a video downstairs. Taking a chance, they got friskier. Mom started going down on dad.
To their horror, they heard footsteps coming up the stairs. Their daughter walked past their nearly closed door before they had a chance to shut it all the way or at least break their clinch.
But the daughter walked on past and they figured they'd dodged a bullet.
The next day, mom discovered otherwise.
"Mom," asked the daughter, "I saw something yesterday that really confused me. Now I wasn't spying or anything but when I walked past your bedroom door yesterday, I saw you and dad. You told me babies get made when dad puts his, well, um, you know, in your vagina. But I thought I saw him with it in your mouth. Really, I wasn't spying, I just saw it, and you said I could ask anything about this stuff without being embarrassed so I am."
Mom took a deep breath.
"Baby, what I told you before is right about where BABIES come from. What you saw yesterday is, um, well, it's where JEWELRY comes from."
