I'm fairly sure (about 90%) that the girl in the middle of the montage image that I posted previously (with the ping pong paddle) is Stephie from Digital Desire who's also known as Laura from Gator Girls.
I'm also somewhat sure (say, 70%) that the girl on the left: Laura from Bachelor Magazine is probably ALSO the girl on the right: Helena. I THINK (about 85% sure) that Helena is also actually Laura Singer, a British blonde who did some hardcore a while ago.
However, I remain VERY unsure whether Stephie/Laura is the same person as the Laura/Helena/LauraSinger... I think Stephie/Laura is y0unger and smaller-chested than Laura/Helena/Laura Singer, and that the Stephi/Laura pix are newer... the Laura/Helena/Laura Singer content is older, and she looks a bit older in them (compared to Stephie/Laura) so it's unlikely that they're the same person. Or at least I think so, if I haven't already confused myself.
And I'm also not 100% certain that Laura Singer is Laura/Helena.
A cap of Laura Singer attached. Any clarification appreciated.
