A expertly made xxx porn scene is 50 % the facial
expressions of the girl. She need not be a beauty queen
with plastic surgery. In fact, she can be slightly
LESS beautiful, that makes her more sexy when she
emotes feminine from her face and body language.
When the producers make NOISY jumping porn they
take away from its sexiness. Then also they let the
edited scene go on for 45 minutes, by that time
you can be bored with it, with the brown skin color
and the noise of the girl shouting how she is enjoying
the sex.

Like any film sequence development, porn video should
also have a BUILD-UP before the sex scene arrives.
See how John Leslie seduces a nurse in a doctor's office
in the first TALK DIRTY TO ME. The sex scene is only
about 5 min but the seduction is so very well done.

Even some of the famous xxx porn studios have
carelessly designed films.

Also, in each scene keep the girl's ass, leg flanks,
and legs, all the way to her high heels in the frame
so she is "present" in the view. Sometimes close range
is okay, but 50% keep her entire sexiness in the frame.
