The movie end credits provide names of the female cast (which are the same as shown on video box cover):
Foxy (who is Niki Belluci), Angel, Cassy, Allisan (note how it spelled here) (here she has dark hair and is featured on video box cover), Ursula.
Male cast: Lex (who I assume must be Leslie Taylor, by process of elimination), Nick Lang, Frank Gun, John Walton
If I am to assume the female performers outlined in the scene breakdown of IAFD databse is accurate, Cassy is a lanky attractive blond for which you have no foto. She has a large mole/beauty mark/blemish on ass cheek (near vagina). Having done some verifications, I can confirm that it is this Cassy: http://eurobabeindex.com/sbandoindex/nicol.html and this appears to be have been her only movie credit.
By process of elimination, one must conclude that "Ursula" is Cynthia Fox who appears in the next (3rd scene) with Leslie Taylor. In EBI and IAFD database, she does not appear to have used the name of "Ursula".
