Sort of playing on the contrast between her supposed pureness and the depravity of her sex acts. It's the "I can't believe I'm doing this" 
appeal , and of course the more extreme the more exciting. When vaginal became to commonplace, anal become the new extreme, then double anal and so on.But today so many performers appear to take it all in their stride like if it was second nature to them. It's the case with most South American girls: Sereia Ninfo, Aylla Mei, Sayuri Sakai, Daniella Ortiz or Vicky Simmons, but also girls like May Thai, Ambra Dolce, Ria Sunn or Moona Snake.
This kind of performer doesn't even bother to pretend to be innocent or overwhelmed. She's a hardened pro showing her abilities in a relaxed, casual and often playful fashion
In the same way she tends not to let her beauty queen status interfere to much with just being an easy-going, confident and completely down to earth young professional on a work assignment
. A miss universe with her mind on doing her job by using her very best oral and anal skills. And even if these girls are great entertainers with strong personalities, it can perhaps seem a little straight forward and routine for many viewers. In many scenes the girl is arriving on the set, twerking her butt , helping the boys fit tightly inside it so they can enjoy her DAPing skills, milking them clean like the pro she is, swallowing their cum, winking or gaping her butthole at the camera, and she's back to her everyday life
. It's a kind of business as usual style, which doesn't mean sloppy or poor quality. Quite the reverse, totally professional but also no big deal for the girl.It's interesting to see how the market responds to this sort of performer, is it a turn on or a turn off ? In some ways it is more real and genuine of course, but perhaps most porn viewers still prefer a girl pretending to be pure, dazed and flustered.
