My dad is 63 yo and he's a widow, I'm 41, divorced and with a son. After so many years I still go and meet my dad in secret to have sex. We have a normal relationship and we never show to anyone in the family or friends that we are also lovers. We normally meet during my lunch time, I tell my son I go to the gym, or to the spa and I sneak to my dad's place for a quick fuck, like we do even when my mom was still alive.
