She says that after she got divorced from her son's father she had a relation with her own son for about a year, then she met her second husband and their relation ended, but she never forgot how much she liked having sex with her son. Once after being drunk for having a discussion with her husband she let it slip and told him he had sex with her son, for her surprise he didn't got mad or hungry. After being quiet for a few minutes he only asked if she would like to do it again. The video was made by her husband and as you can see the answer was yes.
