For several years, we have been living together with my father, but shortly after living together, my father came to our couple's bedroom to sleep with my wife.My wife, who was initially against it, now wants it, and even though I was sleeping next to her, she said obscene words such as "I prefer your father's big cock" and "Put it inside me so that my uterus is numb". And I'm even doing creampie SEX.In addition, my father called his friends to his house, made them attack with electric machines, rotors, and vibrators, and was doing a perverted act of getting excited when he saw his wife spree.Even though I witnessed such a scene, I didn't have the courage to criticize it.
