It might have had a few slips but the bj she gave was on a dildo, unfortunately.
The fact is, even the "uncut" content was edited. Anything really graphic never would see the light of day. Mumblez was very clear in private convos that he would never release anything too explicit out of respect for his wife and keeping the peace. He said on the website itself that anything with his dick in it would never make the cut. So, I think, barring an unforeseen hack/leak, we will never see anything remotely hardcore.
My fingers are crossed that AI advances to allow full body simulations before the alien invasion wipes us from the planet (goodness knows Nikki made enough content to sample).
