Girls are like 65-70% because many have certain types that they get rock hard for.
For instance I usually don't like thicker girls unless they are just a bit thicker with still a pretty fit stomach and tight legs and have killer curves.
A girl like Tru Kait and Jewels (current body type) is a bit too thick while Leya Desantis, Shalina Devine and Melissa stratton all are hot to me without necessarily being a skinnier and real tight body and small hips like Molly Little , Tiana Blow, Venus Vixen or a Kama Oxi.
The next huge part is positioning and angles . These are the top two by far.
Get the distances and angles right especially in pasthrough and it makes all the difference in the world.
The video I think that nails practically everything : make up, lighting, distance, room or environment, perfect stunt cock you can relate to (not too fat or super long), sex angles, dirty talk, outfit, sensual build up and seduction and most importantly perfect eye contact is Neural Link with Mellissa Stratton.
