One day, little Mikey came home from kindergarden and couldn't find his mother. So he headed upstairs and opened her bedroom door.
To his surprize, he saw his dad stripped naked on top of his mom, who was also naked, both heavily into the sexual act. Not wanting to traumatize the boy, the parents continued to do what they were doing.
After a couple of minutes, Mikey asked, "Daddy, can I climb on top and have a horsey ride?"
The dad thinks for a second, "Of course son, we're a family."
After a couple more minutes his mother starts moaning and writing wildly.
"Hang on Dad!" cries Mikey, "This is where me and the mailman usually fall off!"
