I'm thinking the actual cocksuckers are porn actresses but the rest are everyday women who agreed to be in the vid

That is most likely because even if a woman was tempted to suck a stripper cock, VERY FEW of them would want to have their face on video, and even less would be willing to get a facial and have that posted online. Even for their job/career... many employers these days have clauses about employment conditions, so they'd never risk it.
