My thoughts on this yesterday involved the fact that I am loathe to punish failure in CR, because it is a natural reaction to stimulation, and it may be that I am the reason my sub came. In other words, I misjudged the edge.
That being said, I think we need more information to answer this question. Was this a deliberate act, or simply slipping over an edge that can be hard to define? If the latter, this thread is probably more than enough punishment, if the former, I would vote for more CR thraining and a long period without cumming.
