I had never noticed how many cards there are with hotness level XXX in both a- and e-series cards.
It has to be pointed, also, that another probable reason for such a thing was precisely the fact Virtuagirl and Deskbabes were two separated products, at the tIme.
I mean: the neverending debate about XXX content was already there, and, while some people would have preferred XXX content to be always and only on Deskbabes, there were also some people who would have appreciated to see some XXX clips on the ordinary product too, sometimes - and production of such clips was probably aimed at them.
Personally, aIso, I don't think there ever has been - both in "separated products" and in "only a product" times, any model who went too far - or less far - than how planned: this is a professional product with professional models, so in any case models did probably - and it was shooted by crew - just the content which had been planned, and agreed to, in advance.
