I agree flaifil; and the scene does contain a number of my porn dislikes. I found what you mention (as well as the mullet-headed cameraman d-bag diving face-first into Nikki's crotch) pretty annoying.
Still, it was a request and I really like the two gals involved. They were into it and obviously having fun so that helped. Besides, the title of the movie includes the word AMATEUR, one shouldn't expect epic filmmaking.
