*exhales* Wow, I LOVE how vulnerable Severus is here, once Harry gets past his barriers that is. And I adore that you had Harry get proper training. That just highlights how much Harry cares about Severus and that this isn't a casual thing. And the way Severus just...relaxed at the first touch of the ropes. Guh! And OMG, Severus being his snarky self in the end threatening Harry when he was about to undo the knots too soon was PERFECTLY IC, *g*. Fabulous job with this, mystery author. Really beautiful handling of this kink. :)
