Wow. I have to admit that you've really made me think with this story. *I hate when that happens* ;) To be honest I never understood the BDSM attraction (not that it stopped me from reading it) but you've done a great job explaining it within the context of this story and I had a dawning moment when Rodney was being spanked and his sudden release of tears. Kind of that "oh..oh...oh...I get it!"
Anyway, don't mean to ramble on. Just wanted to let you know that I'm really enjoying this story.
