Most of the new girls who debut in any year don't make a long career, for whatever reasons. I also have one or two vids by Kayla, turns out she's one of the majority of girls who made a few vids and quit. That's life, for JAV fans.
Personally I don't pay any attention to a new girl until she's released at least 5 vids. Almost every time I download a debut vid is at least 6 months after release, after I've watched at least 3 of her vids and decide I like her and want to see what she was like when she had no idea what she's doing. Very rare that I become a fan of a girl who's made fewer than 10 vids.
