Rustam1990 when a girl spits (in a seductive way) from her mouth to the viewer
I would definitely prefer spitting to the viewer over showing their armpits to the viewer (which works about as well as looking at the back of a knee without the taste or smell). An interesting aspect of this is also that anything that appears dropping towards your eyes in VR seems to trigger an actual protective reflex in your real body (happens also with peeing and sometimes with long hair and even works in 2D, e.g. when a ball is suddenly thrown towards the camera). This may not be the most pleasant experience of all, but I like how it blurs the boundaries between video and reality.
I am wondering why there seem to be almost no attempts in VR porn to hack a little bit more into the physiology of the viewer to create an enhanced immersion experience. Not sure what exactly would be possible but I remember once watching a VR rollercoaster video, standing and with nothing around me to hold on to, ending up in an almost-panic attack combined with complete loss of orientation. While this experience was very unpleasant, I think it would be great if there were some subtle ways in VR porn to trigger some bodily reactions in the viewer that might enhance the feeling that they are actually part of the video.
