sex
Plug it in! Plug it in!

A very pleasurable experience that may cause a child, but I have a definition to prevent this child. (Remove plastic if you want to have a child).
You first take the wrappers (known as clothes)off. Then you take the plug (or penis) and you put plastic (known as a condom) over it. Now you then take the plug and put it in the outlet (known as vagina) and plug it in. You will feel emense pleasure now. Normally, the electricity (or sperm) would go from the plug to the outlet (reverse to normal plugs and outlets) but thanks to that little plastic, the sperm wil not flow.

This is known as sex. Have fun.

Something I learned about in Catholic Schooling.
Priets like to have sex with little boys. I like to have sex with big boys. Guess, I am not a good Catholic anymore.
