Well not quite but now I've got your attention, did the thought of that gross you out or was it something you thought, "Wow, that's for me"?
I know I've had many instances of girls I introduce to breast bondage either being afraid of it or just not getting it becoming totally hooked once they try it. On the flip side I had one gal who for ages wanted me to cum on her face but when I did she almost threw up! Not the best outcome...
Care to share things that you've been asked to do that just went too far, or perhaps you surprised yourself and you liked something that at first sounded awful?
