Holy crap dude, that's the most fake, contrived and overacted POS scene ever put on celluloid.
Here's why:
1) To do those gyrations she'd most likely drown herself
2) To have sex in a pool like that, with the water washing away ALL traces of lubricant, she'd have to have a saudi oil well in her pussy to keep it lubed up (otherwise they'd both have rubbed themselves raw).
The only saving grace in that movie is Gina Gershon. Now it wasn't the worst movie ever made but it was in the top ten.
Now the pool scene in "Wild Things", now that's a hot pool scene.....
