This is one of the funniest scenes ever. The effort towards a more hardcore softcore porn make this ridiculous (def. a waste of beautiful talent). The brunette acts as though she's attempting to hit a nail with a hammer using only her feet! The orgasmic gyrations and earnest breathy exclamations make us question whether the actress has ever actually had an orgasm herself. This was just silly. (And wasteful.)
Simulation.
What are these actresses doing?
