After my mother got dumped by her last boyfriend she was very sad and depressed. At first I thought she really liked the guy and it was very hard to see him go, but no. When I asked her she told me it was nothing to do with that, she was depressed because in all his life this guy was the only one who made her reach for orgasm every simple time they had sex, she didn't know why but she thought it might be the fact that the guy was her best friend's son and that made all the difference in her head. So I proposed my mom, why not try with your own son? She told me months later after we've started having sex that the moment she heard me say that she immediately felt completely wet.
