I don't think you will see much more then what we see right now unless Nattie fucks off, shes the 1 holding her back, as soon as Jenny looks like shes about to show the goods, Nattie moves the camera away, you can tell how much of a naughty slut she wants to be with the voice msges some people have posted online about her talking about having them put there big hard cock deep inside her wet pussy, or her wanting to oil your hard cock before she spreads her legs nice and wide and tells you to fuck her really deep.
Why does she do this? because Nattie has no control over it, Nattie wouldn't even have a clue about these msgs, this is something she can do herself without Nattie finding out, unfortunately she doesn't know how to fucking record videos of herself and needs her sister to do it.
