One time my Mom walked into the house from the garage, and me and my girlfriend were naked and fucking right on the couch in front of her. I'm sure she saw gory details, peneteration etc.
I got up and ran full speed upstairs, blaring hard on slapping my legs with each leap, leaving my girlfriend to deal with her.
It turned into two against one bitching at me for leaving my girlfriend there to take the heat. Fucking women.
I was 15.
