This just does not look real to me. I did a web search and did not find anything convincing. However, if it is not fake, maybe it is possible to pee while cumming, and perhaps that would add to the sensation? I actually do not know if it is possible to pee while cumming. As a teenager I once had a boner that would not go away and I had to pee, so I peed in the shower, but I do not remember that being pleasurable.
