Damn it, everyone thought this piano teacher was a pro at his job considering how solid was mademoiselle's resolution to attend the lessons... Well, teahcer is a pro, that's a fact. He's a pro indeed at seducing his pupil, a young demoiselle with a hairy bush... When mummy finds out what the lessons are actually made of, guess what? She'll give a "hand". Well actually, she's going to fully participate to this orgy by the piano with her husband, her step-daughter and the piano teacher![French late 1920s]
