The gif is irrelevant, I just need something to post, if you want the source on that, ask.
So a site like kink.com or something similar to that (it was the website that films in the wooden barn with the black metal bars to hold down women) did an experiment where a woman was treated with a fucking machine for two hours straight. At the end, she was in a kind of state of shock, unresponsive at least.
This was done in a documentary style, as someone was explaining the dangers of doing this.
So, does anyone of you find it?
want to know too
