A mother is in the kitchen making dinner for her family when her son walks in.
"Mom, where do my baby brother come from?"
The mother thinks for a couple of seconds and says,
"Me and your father fall in love with each other. One day we go into our room, we kiss & hug, and make love.”
The son looks puzzled so the mother continues,
"Which means dad puts his cute little dick in mom's vagina and that's how you get your baby brother my son"
The kid seems to understand.
"Ohhhh... I see, but the other day I saw dad's cute little dick in your mouth. What do you get when you do that?”
"Jewelry, my son. Jewelry."
