Initially, I only intended to teach this son about a woman's body... But then this son, with his sturdy dick inside me... desperately moving his hips on top of my body, the pitiful expression on his face made me feel both sad and happy, and I blurted out obscene words: "Faster, harder, shake your hips!!! Ram your dick into mommy's pussy, dig it in, stir it around, twist it!!"
