In a thread back in June you asked the question, regarding Sarah Young :-
"does anyone know has sarah done....dpp...dap...or fisting she seems to have done most things,,so just wondered...thanks."
I then gave the answer to that as : No, no and no. Unfortunately I have discovered that I was wrong.
Since then I have re-watched some of her films and noticed that, in the film "The Flying Doctors" (also titled "The Flying Nurses" and "Le Porcone Volanti"), she does in fact perform DPP with Christoph Clark and Jean-Yves Le Castel (Erica Bella is also in the scene).
It's a very short clip, and if you blink you'll probably miss it, but it is there, and it's the only time I've seen Sarah perform this.
