My mother notices my morning erection. Such a mother, as she does housework, I consciously notice her big ass and cleavage, fully erect as a teenager. The mother, excited to see her son's dick, secretly grabs it and says, 'Keep this a secret from Dad, let me teach you about a woman's body.' In the bathroom, in the kitchen, while Dad is out, she inserts my dick into her ass. While Dad is sleeping beside us, she mounts on top of me.
