Virtual or reality? Neighbor doesn't notice it, does it?

My neighbor is constantly watching this new virtual reality porn. And when he told me about it for the first time, I naturally became curious. I had his spare key and snuck in because I wanted to borrow his VR glasses. But there he was lying on the bed and was completely immersed in the video he had just watched. And then it became not only virtual, but real for him. He really thought he was still in his porn at the beginning, but at the latest when he warmed up he knew that it was real, but so real.
