Ok. The main thing about this idea is the location. Toilets look pretty much the same the world over. Also toilet is the one place where you can try and secretly sneak into to have some great VR wanking experience. To make the immersion complete, lets have the scenes take place in the toilet. You can have the girl standing over you, sitting in your lap, leaning against the sink, sitting on the sink/desk. Great possibilities for positions, especially for those nice immersive close ups. So grap your VR goggles and head to the john :)
