Back in the older days there were stories (not good ones mind you), but they tried to create plots which introduced different types of sex scenes. A single movie would have intercourse, blowjobs,
Anal, double penetration all in one film.
The movies today are basically the encapsulation of a single fetish: Double penetration, Two girls one guy,
Anal, Blowjobs, Handjobs, etc..
If you haven't seen porn in a long time you might want a little of everything. Instead you get to choose a fetish, say Double Penetration theme, it's like 3 hours of the same Double Penetration scene with different girl in each scene.
Also, I hate when the women don't seem to be having fun. If they look like they are not happy, or if the guys even pretend to be mistreating them I just want to turn it off and take it back.
I'd love to find real (non staged) videos, but have never been able to find it.
