Question about watching porn?

I live in Ontario Canada. I watch on xvideos.com.

I do not download, upload or anything of that nature. I do not have a collection or what not.

I only watch on my iPhone.

While watching a video I accidentally clicked on a video that said like son and mom real or something like that. I clicked closed and the window closed right away. It was a slip of the finger. My fingers are big and the screen is small. The video did not stream/play or anything. I have no interest in that stuff. Real/ fake it is disgusting. I don't watch anything with questionable titles or thumbnails. I only watch the videos for recreational purposes and do not share or do anything like that

Is stuff on xvideos legal? I'm assuming everyone is overage and actors. I'm sure they have mods or something to get rid of videos.
