For such a seemingly simple topic, it has certainly led me to a lot of complicated reactions. On one hand I totally get it. (In fact on a RL FLR DD blog I frequent, I often feel similarly because I feel like I'm the only DD husband who doesn't have an issue with getting things done and not indulging to excess..... whereas the majority there are punished for mostly those things.)
But what about responsibility and taking action when action is required? How "alpha" does someone have to be to be responsible without being disciplined? To me they are unrelated. And how alpha is alpha? If an "alpha" submits to another....are they still really an alpha? Would a true alpha ever submit? What you describe domestically and professionally is not exactly my situation, but very close.....and yet I don't consider myself "alpha". So if you are looking for 'spanked alpha' stories, maybe it's like looking for 'living ghost' stories?
But what of the actual stories you speak of that don't meet your situation? I can't think of too many instances in mine where the punished husband is a perennial slacker. They are often seemingly normal guys who prefer a certain role. But they definitely aren't uber/alphas either. Only a few of mine portray profoundly submissive guys. Most are pretty regular, functional to highly-functional men. What would they need to have done in the stories they occupy to fit what you are looking for?
So what are you really looking for? Regular guys who are capable of action and decision and even have respected expertise in home matters who also submit to their wives? Or an alpha "on temporary vacation"? And if you do a story of someone who submits "on vacation" (I actually have a story like this) the meat of the story is still going to portray the male submitting......because he is. It seems like the 'alpha' part would have to be some qualifier in the male character's exposition rather than some key element in the narrative.
You mention 'spanking as escapism'. That's interesting too. There are all sorts of escapes for a busy, weary alpha to pursue (a vacation to a resort? a cruise on a luxury liner?). And none involve submitting to another for a spanking. The alpha remains the "top dog", even while relaxing from their usual pressures. Choosing to be spanked as an 'escape' bespeaks something different, don't you think? Something "not entirely alpha"?
To do this the situation requires a rationale where the spanker is not really dominant but is just 'giving the guy what he briefly wants'. That could be a good 'guy goes to a pro' story (not my thing), or a 'guy gets his wife to do it.......but doesn't want her to get too used to the idea' (also not my thing). All of the fun in dealing with the mindsets of people who dominate and submit is absent in a story like this because it is important that the alpha maintain his 'alpha-ness'. Where's the fun in that? I'm sure a lot of "otherwise alpha guys" DO go to pro-Dommes for such service......but I can't see reading about such a transaction being much fun. (The story could be very short though: "John was tired from all the work and decision making he'd been doing and so he called up "Wicked Wanda" for a session. He showed up on time and she spanked him hard. Then he paid her and left. The End)
So as you can see the psychology behind all this is complicated and possibly a bit tricky .....or even weak for a fleshed-out story. But maybe the solution is simple: you could take the M/F story you like. Cut and paste it into your documents, edit out the names and switch the genders around....and bingo! Problem solved!
