Smooth transitions.

Now I know I talk about them a lot, but smooth transitions keep sexual sensations where they are instead of causing them to go to an abrupt stop while your guy waits on you to do whatever it is you're doing.

Here's a great, short example of an amazing transition. At 22:20, Lexi Belle is fucking her guy on top and facing him. She then turns around so she isn't facing him. She does so quickly and effortlessly. And she does so without his dick ever leaving her pussy. It's such a small thing, but guys love this stuff because, for the most part, only porn stars do things like this.
