Valentina Bianco is 33 but you’d be forgiven for thinking she’s less than half that age. Alas there’ll be no marking of her bottom today (got to respect a working girl’s need to turn up to her next shoots in one piece) but in all other respects – choking, face-slapping, face-spitting, facefucking, you name it – she pretty much loves being treated like a piece of sh*t.
