Write a story about a guy in a cuckold marriage whose black bull lives with him and his wife. Only bull is allowed to have sex with her. Cuck is kept in permanent 24/7 chastity and only allowed to suck bull’s cock and lick wife’s pussy when they are having sex. She also might play with his caged frustrated balls and clitty when the bull is breeding her. The only way to get sexual relief for cuck is a sissygasm. He’s allowed to play with a dildo once a week and once a month he has anal sex with bull. Bull always dumps his black seed ballsdeep in wife’s pussy to get her pregnant. Once it happens, the wife will keep the baby and the cuck must raise the baby. Cuck is unhappy, but will not leave, because he loves his wife too much. Wife loves the cuck too and pities him, but the thought of them both submitting to a superior black man to the point where her they’re not allowed to have sex with each other and must raise his black baby, while the cuck is kept in permanent chastity as a sign of admitting his sexual inadequacy, is too much of a turn on for her
