NASH-939 - Observed by my son during sexual activity, reaching climax with rapid thrusting! A 50-year-old mother inseminated with viscous semen.

When I returned home and tried to open the door, I heard my mother moaning! My penis became erect as I faced a sight I could never have imagined from my usual mother! "Ah'~ iguu" I never imagined my mother would make such a sound! My mother, climaxing and inseminated with vigorous thrusting, had become female!
