I have only ever seen one video with Sara St James that I would call hardcore... and it's a solo scene with finger penetration and a black, gold tipped vibrator. Otherwise, it's all simulated, softcore, including the boy-girl set where the guy's penis gets really close but there is no actual penetration.
It's too bad, she was a beauty several years back and quite a personality as well. She never really dove into the deep end of the porno pool though.
