no need to be embarrassed/apologise, there's so much posted on here it's easy to miss things and as I said it's good to be reminded of things posted a while back.
It's a great clip, thanks for bringing it up again.
As you can probably guess, it has been posted before (think there's several threads in the 'mainstream clips' forum). There's also a thread with a tonne of pics of different girls in the same set of stocks so worth having a look :)
Mary (Patti Clare) and her daughter-in-law Angie (Victoria Ekanoye) visit a spa before Mary's wedding.
Lots of great sole shots as well as a bit of toe scrunching/flexing.
