OK. They seem to be on film, but so far just g/g.
An exhaustive search leads me to conclude that these twins are being hawked by the same people who turned "Cherish & Cali Marie" into the "Milton Twins" and also did the "Simpson Twins" [whom I don't care for].
These are called the "Texas Twins" and have an incipient web site with little in the way of samples. They promise b/g action, but it seems all g/g.
Once again they put an emphasis on the implied incest potential (though that does nothing for me, personally).
The background of these is more corrupted rich spoiled princesses than the "naive" act of the Miltons.
