F-250 syndrome
You get so mixed up between the twins that you end up giving head to the dad because he looks just like the sister.
I gave head to her dad and thought he was her sister. I got a weird look and a confused dad.
Her dad walks in, I say, 'Are you my sister?' He says, 'No, I’m your dad.'
I was doing head and her dad said, 'That’s my daughter.' I said, 'That’s my sister.'
