One of the reasons why Phoenix is even hotter than Jayden is that her arms and especially her hands are more delicate and feminine, Jayden's hands are a bit more plump. Some might say it's not that big of a deal but I think it's very noticeable in this scene.

This is the first time ever I've seen a Jayden Jaymes scene in which the other girl is even hotter than her. Usually Jayden is the hottest person in any room and it's not even close but Phoenix Marie in her prime was something else and this right here is a perfect example of how she could even outshine someone like Jayden. That's crazy.
