Sexlife from the beginning

It all began when I was a 5 years old kid. At home at that time we had old computer, where I could watch movies for kids. I did not know how to read so I always remembered where are the fairy tales. I clicked as always but there was not fairy tale it was porn. I still remember everything what was happening in that movie. There was a man f*****g a woman in the gym changing room. The woman was sitting on the bench and he was f*****g her. At my age a did not know what they were doing, but it fascinated me. In the end he just took his d**k from her and came on her belly. And I was asking myself why is the man peeing on her?  From this experience I could not think about anything else but what they were doing. I wanted to see it again but I never found it.
