Ultimate shoulder rides

Hi...you've posted two pics on the wow bonus album, today they are at page 9, in the second line from the high side. I've commented one of them, they represent two sisters (I think...), and the younger is carrying the older; both of them are blond girls and the pics are taken in living room (maybe...)
I'll be really really glad by knowing some details about them...the most beautifu things would be to get in touch with them, but It'll be enough just to know their age, weight or so...
thanks!
ciao
