The closest was when my grandparent walked into my room and my back was facing the door it looked like I was playing with myself but when they walked over I was just button mashing a ps2 game (don't remember game) but needless to say it was a funny moment.
So just remember button mashing looks sus if your looking from behind.
Honestly I do not know. Imagine someone with VR glasses enjoying a porn game and unaware of their surroundings. That would be me. I also like OPs story.
Non, but I have nearly been caught watching. In my teen years the windows desktop was my favourite thing to look at on my computer, at least everytime the parents walked in
I improved my game and have fapped while playing porn games in the same room as other people. Never got caught, its all about controlling what the others can see from their POV and having a top poker face
