As a Dominant is easy to forget the trust and comfortability that a bottom needs to scene in the first place. And I have little respect for tops that brag about not doing aftercare. The same level of trust and safety that you facilitate in order to scene carries over to allow someone to possibly break down at the end of it. This is not the time to freak out. Hold them, and stand guard until they can put themselves back together. If you don’t have the emotional depth to handle this then make sure you or the bottom has someone to provide it. Aftercare is as much a Top/Dom skill as 6 point Florentine flogging. Don’t be a shitbag and act like you can’t see the naked, vulnerable person having a meltdown because you’re a emotional coward.
