From AV, a son who wants to have sex with his mother right in front of him, and a mother who loses her sanity seeing her son's erect penis. A favorite AV of the son destroyed their parent-child relationship... However, in a sense, AV also made this parent and child happy. "For educational purposes..." the mother said while watching AV stimulated the instincts of the mother and son, turning the mother into a female and the son into a male, causing them to bloom.
