Little boy walks into his parents room one night…

And his father is on top of his mother having sex with her. The boy runs out and goes into to his room. The father heads over into his son’s room, nervously laughing,says … “it’s ok son. That’s how we express our love for each other. The boy furiously storms out and goes down the hallway into his grandmothers room. In a few minutes, the father heads to that room and opens the door. The boy is naked and on top of his grandmother, thrusting away. Turns and looks at his father and says: “It’s not so funny when it’s YOUR mom now is it!”
