Just wanted to comment on what I've seen between Trevor and Aaron that I think all kinky couples (and others too!) should have. There's dom/sub, of course, but there's also obvious affection and respect: respect for boundaries, preferences, comfort and discomfort, etc. I wish that more BDSM fetishists would value those qualities more highly.
At any rate, if you haven't checked them out, you should. ;-)
Have fun, be safe, and show each other some love.
