I know this is now an old post, but it appeals to me now that I'm back ...
I don't know if this is accurate, but what would happen if the guys penis was 'tied down'? I mean, if it was tied with a string to the back of his belt, so that if he got even slightly aroused the string would get tighter and tighter, causing him intense pain each time?
Hell, for all I know, this is a regular feature of male submission ....
Hmmm, I wonder if you can tie up a woman's clit? I guess if you had a thin, strong thread ... gotta go, bye!
