U: Uniform
There is no such thing as a standard cuck uniform. Different hotwives/hothusbands may have different ideas of how a cuck should go dressed. Some like most of their life to be more or less like before and the cuck doesn't really dress any different -- except for one small but important detail, of course. Others like to keep their cucks naked and collared at home, or even in a humiliating maid or sissy outfit. There's no right answer here, and it all depends on your own dynamic and preferences.
But, one thing almost all agree on: any cuck uniform must include a chastity cage. Even if you're still wearing your regular clothes at home, there should really be a locked cuck dicklet underneath there!
That uniform achieves so many important goals. First and most obviously, it keeps you safe! No unauthorised playing with yourself, no dirty perverted rubbing one out while your hothusband/hotwife is making beautiful passionate love to their bulls -- don't be a creep!
Secondly, it keeps you in your place. It reminds you that you are just a useless little boy (especially if you're also neatly shaven), even if you're much older than their bull, and it reminds the bull that you're no threat to them. Unlike you, real men don't like sharing.
And, thirdly: your denial only makes you more desperate to serve and please them in any other way you can. The cage brings out your natural submissiveness!
