I lived in Germany and dated two german girls, and talk from experience here without insinuating anything.
They are known for having a strange approach to sexuality. Have I ever come across a set up with a man is nailing a daughter and the mother? yes, but nonetheless we can't just pluck it out of thin air and post it openly on a forum as it's a heavy accusation and even with a tongue in cheek approach I think it crosses the line personally.
She is hot though....and Wolf is on many grams of AAS a week...it must take a lot of will power when she comes out of the shower with a towel wrapped around her...etc.
