A few more conventional mishaps aside, there was the thing with the chair. He has this large and comfortable office chair, which he decided to tie me to (which actually worked like a charm). I was pretty much immobile -- unfortunately the chair wasn't. When he decided this was the time he wanted to fuck me, the stupid chair began to wander across the room. I had to giggle, but suppressed it somehow -- the the very moment where he almost fell because the chair moved faster than he did. In that moment it was over, I couldn't stop laughing anymore, which made him laugh (and say something between the lines 'Goddamnit, I wanna finish that!' which made me laugh even more). It was hilarious. It was hopeless. But seriously, we learned a valuable lesson: always block the wheels
