Inlaws

I came home from work early today i noticed my father in laws car in our drive way.
I hoped he had come to replace a part on my water heater
When i stepped inside i heard the tall tell sounds of sex
I found sara in her sex swing and her dad Philip fucking the hell out of her
I pulled out my iphone and filmed a few minutes watched a few minutes then left for a while
I wached my wife sara 36 fucking her own father in a sex swing wearing lingerie moaning out cum in me several time before it started over her high heels pointed up ward her dad pulling her on to him. Philip 54 navy vet still in good shape really drilling my wife sara his daughter
Im confused turned on angery betrayed all at one and all i wanna do is rush home put her in that swing and tear her up
