This picture reminds me of a story my ex husband told me about growing up in germany in the 60s. Apparently his famly hired a 25 year old woman to the nany/caretaker for him and his three younger siblings. He was the oldest. Anyway, so the story goes, when he became 'of age' she apparently began catching im in the act of masturbation. Like any good kinky at-home story,her room was conveniently next to that of her teen-age-charge, my future husband. 

She would visit him at night. She would suck him. She would put her tongue up his asshole. She would ride him in his bed...

"It would be a Saturday after family dinner and I'd be in my room with her naked tits squashed in my face, and id be just fucking her... fUUUCKINg her.  Or rather, she was fucking me.  And I could hear my parents talking and putting away dishes downstairs.  It was absolutely an erotic fantasy come true!"

He said that after a while his parents knew, but that they wanted him to have the experiene of a woman.
