It's often hard to tell one porn movie from another nowadays, because you don't see any differences in the motivations and the characters of the people having sex. It's like everybody is the same, even though they look different.
When there are no characters in the movie to play, then the guys and the lady end up being themselves every time. It's like they are playing exactly the same characters again and again in each and every movie. This kind of thing is bound to get boring after a while.
Perhaps porn movies need a little more sex-story-line to make themselves unique and different from each other. When the guys and the lady are playing different characters, different from what they really are themselves, then they change the way they have sex to correspond with their characters. It makes their sex acts unique and different from one movie to the next, because they perform the same sex acts in a different way every time, due to their different feelings and different motivations.
One type of sex scene I haven't yet seen is where three young horny brothers end up fighting with each other over one sexy MILF, who has shown some interest in each and every one of them. To make peace, the older lady offers a piece of her nice ass for each and every guy. Her only condition is that they will all get exactly the same sexual favors from her, so that they won't get jealous of each other.
These three guys line up to get oral from her. They line up to bang her pussy, one after the other. They line up to finger her ass. And they line up to ride her between the cheeks with their big dicks.
Their style of sex is similar to a gang-bang, but the older lady maintains their discipline and keeps them in line, perhaps because she is their teacher and has the authority over them.
At one point one of the guys loses his discipline and stays inside the nice lady's ass a little longer than the other two guys did. The other two guys get jealous, and they all start fighting with each other again. The older lady yells at them that they can all have her ass as much as they want. It ends up being a real anal gang-bang for her because these three brothers are jealous of each other, and they all try to get more of her nice ass than the other guy did.
Such a scene would make the sex very different from what you normally see in most porn movies. Because you never see only three guys line up and do a serial bang on a pretty lady. Three guys usually go in parallel, all at once at the lady and occupy all three of her holes at the same time. Another difference would be the older lady maintaining discipline and making the young horny guys line up. And the final difference would be the jealous feelings between the guys that makes them lose control. The lady offers them a free for all between her cheeks to make peace again. And the guys bang her real good, because each guy thinks the other guy got more of her nice ass than he did. Each guy tries to out-do the other two between the lady's ass-cheeks until they all cum inside the nice lady's bum.
This kind of anal sex is bound to be intense and have a lot of feeling, more feeling than you normally see in most anal scenes.
