The Dark Room

Imagine there is a room in a sex club called the Dark Room.
When you enter, you can't see anything, you can't see anyone.
Nobody knows who you are, they can only feel you, not see you.
They can not judge you.
For the next hour, you are totally, sexually, free in that room with 9 other people, men and women.
Would you dare go in there?
Joanna and her husband did.
