A relationship where one officially has all the control all the time is known in some circles as TPE (Total Power Exchange). In TPE, what the alpha says is what happens - always.
I've never liked this model, it always has me questioning if the two of them are damaged from something in the past. The subs in them look so... passive, so controlled, at points even glassy eyed, but in a somewhat frightening to be able to relate to fashion I can see how that could be... comfortable. The quote unquote "alpha" in power however, how is that not a reflection of their insecurity if they need someone who always follows orders, someone who will never challenge them? They seem so much weaker to me than someone who can take that power for him/herself.
I always question how those relationship agreements start for each couple in question. Some of them have one who wants to be dominated to that degree be that way in advance, but many of them require... convincing the person to give their power away. I've seen some sickening (yet psychologically interesting) speech come from people trying to start one of these, some of them not looking too different from how a pimp talks down to somebody. I've even had talks with people who began to fall into believing the shit they were saying, that they're less than a person, that they want and need this, that they don't know anything and need to rely on someone else to know what's best for them, desperately needing a debrief after they've been insulted by such a barrage to resume having a sense of self again much to their later disorientation. Their proneness to beating themselves up seems to be able to be steered by these people, and all they have to do are throw some new scripts into their mix.
Everything that the sub does is in the interest of the alpha or the relationship. The alpha is responsible for the sub and ideally keeps the interest and well-being of the sub in mind when making decisions, though the end decision is always up to him/her.
So many of them don't give a shit about the sub beyond their uses, especially if they're the harem building subtype. Gorean philosophy goes into this rather blatantly.
I saw someone in the furry community trying to build quite the harem this way, complete with his overly-edgy undead fursona, Catholic upbringing that gave him a reason to envy God and demand to be looked upon with the same level of awe, and these really... creepy eyes that are constantly sizing people up and finding openings to insult someone in a way they can be tricked into seeing as comforting.
So... fucking... narcy, it was hard to look at such a creature while simultaneously holding down my lunch.
Sometimes these relationships will have written contracts defining terms that allow the sub to leave or establish boundaries for the alpha, which is kinda pointless since the the aplha can do what he/she wants and has the ability to over-ride the contract anyway.
These contracts tend to be written more with what the dom can get away with more than what the sub can do for themselves, at least for the ones I've had the pleasure of looking over. It's like this "alpha" figure needs that in order to maintain control, to be able to be like "Stop this! This is breaking the contract!" from being too weak to handle it without it.
