Can't wait to see that report...*chuckles*

I'm with the above comments - a whole night sounds like a nightmare come true and I wouldn't want to test it. If it goes wrong, it's too late to change your mind.

I've worn clothespins for longer than 30 mins and was fine...but my dom at the time should have kept his guard on that - when he told me later how long the session had been, I freaked. I'd completely lost track of time and, let's face it, I'm rather fond of my nipples and would like to see them alive and thriving instead of dead...it's a risk I never wanted to take.

...almost two hours by the way...but I wouldn't risk that again.
