The performers they had toward the beginning and middle seemed like hotwives who genuinely enjoyed it. Diane Limber, Candy Cotton, Brittany Sands, Barbie Blazer, Stephanie Love, Alex Gladd, Taylor Lynn, Syndee Belle. Alex Gladd in particular had that "I only fuck black guys" look and attitude about her.
Crystal Ray, Nichole Heiress, Alice Green, Brooke Daze, Allie James, Lauren Kain, and Erin Moore were all mainstream porn stars who mostly shot interracial.
Jennifer Ashton definitely enjoys it and she started the site iirc. I had an account there many years ago and forgot my password so I had to email them. The response came from Jennifer herself which was kind of surreal.
Aubrey Thomas, Riley Brookes, and Emily Austin (my favorite girl from the site) all have QoS tattoos.
