Nazi g/f

I had a nazi g/f, she was like blonde long hair and very polite and civilised because she was a nazi n stuff and I played the part to impress her redneck dad. It was good for a few months and she said she loved me so we decided to sleep together, being the first time I saw her naked I had a hard on and when she saw the foreskin pulled back she suddenly froze and was like JEW JEW JEW and I was like wtf it's not circumcision that's what happens when it gets erect but she didn't believe me.
