This looks more like Male Squirt than a Cumshot (Male Squirt is when you ejaculate clear Piss and Precum instead of Sperm, it is most commonly achieved by post orgasm torture. But you can do it before orgasming too. I have achieved this a couple of times myself, the best way is to rub your lubed up palm against the urethra after cumming)
Still, the video is hot as FUCK!!
