POV sex while eating a big cock

Sometimes I wonder how guys are able to keep up with these kinds of POV sex videos, while a hot chick like this XXX slut is sucking their cock in such a spectacular way. I imagine they probably hire someone to do it, especially in professional porn, but I’ve also seen some great blowjob videos in amateur porn that are equally outstanding. If it happened to me, I’m sure the image would come out blurry, not counting the times I’d drop the camera, and I’m sure I’d only record my stiff cock, and not my partner’s mouth going up and down it.
