A son who wanted to fuck his mother in front of him more than an AV, and a mother who went crazy with her son's erect cock while watching an AV. One of my son's favorite AV broke the parent-child relationship ... However, in a sense, it was also the AV that made the parent and child happy. Watching AV while saying "for education ..." stimulated the instincts of mother and son, and made the mother bloom into the female and the son into the male.
