"Brother husbands" sounds a bit like a reverse harem, so not sure how that might work. For a single husband cuck whose woman has many (possibly dominant and uncommitted) lovers I would think certain things are mandatory, such as a waiting meal, bubble bath, massage, and facesitting offered each night/morning when she comes home. She chooses whether to share any details of her day or what she did or with whom. The husband should be required to remain in chastity in which she or one of the other girls holds the only key, unless she lets him out, so that he can never cheat on her or pleasure himself without her permission. He would be entitled to a weekly prostate milking at least, for health reasons (ejaculation without orgasm and eat his own cum), but would of course submit to her at any time and in any way she wanted, including being shared by her with the other girls for her amusement and his humiliation and reinforcement of his submissive role.
He should take her shopping anywhere she wants to go and be prepared to buy her clothes, jewelry, vacations, anything she needs to maintain her ability to fulfill herself sexually. He should provide her with a home and full support, while any money she earns she keeps for herself. They could negotiate what here share of his wealth gets transferred to her. He should take on most of the domestic responsibilities and provide the income. Also the nature of the D/s should be agreed upon - they might present themselves as a vanilla couple to the outside world and keep the kink private at one end of the spectrum, or live under a TPE arrangement complete with public humiliation of the husband at the other end. She should define the role he will play and he will accept it.
This is probably a fair trade to be with one of these supremely awesome women until one is living off your life insurance. Any thoughts?
