The full and original versions of some sets are for sale here at JA's site:

Unfortunately I can't possibly afford to spend that amount of money on what amounts to two photo sets. But Becky looks great in the previews. There's also a third unseen girl-girl set, which I believe should be added to the joanieallum site sometime. So there's hope of at least one more set coming out of the woodwork (making a total of four I know of, three now known to have been shot by Joanie plus the red top/shaving shoot).
According to JA (thanks Don!) Becky didn't like the attention her posing received so retired from the scene... so I guess this is all we'll ever have
It's definitely confirmed she's English BTW
