I want to spin off a remark made by the ever-observant Remittance Girl. In the context of talking about how difficult it is to maintain a 24-7, live-together, high protocol D/s relationship, she said: "The times I have had a Dom take out their mood on me in play, they have felt horribly guilty about it afterwards."
Well, yes, I can see why they might, if they were doing it from a not-very-self-aware place.
But blowing off steam through your BDSM play doesn't have to be a negative thing. However, it does require the clear awareness that, 'hey, I had a pissy day today, and I just want to beat someone's ass'. And it requires that you communicate this mood and this desire to your (potential) partner, so that they can say yea or nay.
Lots of masochists, of course, will selflessly volunteer their butts (or whatever) for such a thing. I have guys who specifically ask to see me when I'm PMS, just so I'll be in the nastiest possible mood. They enjoy the idea of me venting my pent-up tension on them.
But even a submissive person can usually find a place for themselves in this scene, if you frame it as them serving your need for emotional release, and keep reinforcing that motivation throughout the scene.
I can imagine creating a whole fantasy role-play scene around it. One could have one's partner play the annoying person du jour, and then you could fulfill those inappropriate, non-consensual fantasies about smacking around your co-worker/neighbor/friend/whatever.
That's what I think is so cool about kink. If you can figure out how you're feeling and what you want, and then communicate it honestly and openly to your partner, almost any mood or motivation can be okay. Clearly, not every fantasy can be realized. But if you exercise some creativity around it, you can do a lot.
