Wow, your description of the proper procedure for a son to have sex with his mom is amazing. Your conclusion about a son’s intense ejaculation in mom’s vagina certainly speaks volumes of truth because ince*st is a universal act that happens every day in many homes.
I don’t know what the relationship is between the young boy and the husband who is sharing his wife, but she certainly has a great sex life for a mature married woman. I see this relationship lasting for several years as long as the wife wants more than one cock ejaculating in her warm vagina.
