I got involved in BDSM 20 years ago with my ex-wife. We only did it for one year, because she didn't enjoy it as much as she thought she would. I liked it a lot, though, and I've maintained residual interest ever since. And I still feel tied (no pun intended) to that community.
And it always torques me whenever we're supposed to identify villains by their "deviant BDSM practices". Most of the people I know who practice BDSM are warm, loving, compassionate, and so on. They just show it in unusual ways.
So I wanted to see if I could rehabilitate these two and show them in a sympathetic light. I've got another commission in the works, a 6-koma comic featuring them. I've also written a doujin script featuring them, showing them as a non-scary BDSM couple like the folks I know. (Said script also does the same thing with Nukui Tomomi-san.)
Yep, I'm now officially a big ol' fanfic-writing dork. I am shipping the fuck out of these two.
