This one seems to alternate between amateur videos and more professional ones. The orgasms aren't the most intense, but I thought each masturbation looked genuine and very stimulating to watch. At about 2 min 27 seconds there's one which is definitely self-shot, the woman taking video of her image in the mirror. The last one is quite intense.
