Pussy Joke Number 13

A man is making love to his wife.
He is really banging her pussy hard, and she is groaning loud.
Suddenly the man feels someone slapping his butt and realizes it's not is wife.
He stops, looks around and it's his young son crying.
He tells the boy, hey I'm not hurting your Mommy, we are making you that little brother you want so bad.
So the boy smiles and the father takes him back to his room and tucks him in.
The next day the father comes home from work, the little boy is sitting on the steps crying.
The father asks, 'What's wrong son?"
The little boy replies, "You know that baby brother you and Mommy were making."
The fatter smiles and says, "Yes."
The little boy says, "Well forget it, the mailman came over today and ate him!"
