I dunno. Why go through all the trouble of faking this if you're not going to throw in some fake moans?
Luckily, I am an expert on this sort of thing. If this was one of those "staged voyeurism" porns, not only would they actually show something, but they would overact the hell out of the embarrassment and outrage at being "caught". The look they gave is exactly the look I would expect from people who would do this in public.
Yeah they have that exact pattern in Dublin bus.. I wonder who makes it, some kind of wizard!?
I'm assuming this pattern has evolved as the prime pattern for blending in many stains.
I was about to say that I've seen those seats, but have never been to Australia.
Fabric seats on any type of public transportation is just gross. A lot of the trains in my neck of the woods have smooth metal seats, and while that does sound uncomfortable, it's really not.
