Lovely and exciting! Reading was a little bit like being on an exquisit emotional rollercoaster: laughing, whimpering, incredulous and turned on. And thoughtful. It is interesting what POV can convey. And what it cannot. I don’t think Tony or Gibbs really know what they let themselves in on and that some difficulties will be complete surprises.
At this point in the story I get the impression that being a sub is an inherent character trait for Tony but he seems to (miss)use it as a crutch, not as a way to unwind and express himself but to hide and I fear that there will be hell to pay when it crashes down on him and/or Gibbs catches him at it. I might be wrong (I often am) and I don’t want an answer from you ^^ that would take the fun out of the anticipation and that would be a shame. I just wanted to tell you my impressions. If you don’t want that, please say so.
