Is it normal to want to watch mom & daughter eat & fuck each other ?

I LOVE to watch MOM & pre teen daughter eat each other's bald cunts and rim each other's dirty assholes and finger each other's bald twats and dirty assholes and then lick each other's fingers clean and dry from blood , cum , piss and shit.
Then watch them both wear strap - on dildo's and they fuck each other from behind on their knees in each other's cunts and assholes and then they both suck each other's dildo's clean and dry from each other's blood , cum , piss , shit.
