Write a very long and detailed story. His dick is too short to satisfy her, so his wife forcefully put him in permanent chastity using a very tight flat cage. He is allowed to touch his wife, lick her pussy and fuck her with dildos and strapons, but he is never allowed to take off his cage. He begged her to let him out, but his wife flushed the key down the toilet and glued the lock shut, so that his pathetic little clitty would stay locked and denied forever. She told him to accept his new life as a girl and only refer to his excuse of a dick as a clit. She likes turning him into a girl and makes him take female hormones, so his body is very feminine and he has boobs. Sometimes he and his wife have sex using a double-ended dildo with one of the ends in his ass and the other in his wife’s pussy. The only orgasms he is allowed to have are sissygasms from his boypussy. He has to cum from anal only. The wife loves big black cocks and is allowed to have sex with any men whenever she wants to and the cuck must always assist her. He and his wife both suck all the cocks and get fucked by them and these cocks cum in their mouths and asses and in wife’s pussy. He must clean all the cocks and all of wife's holes afterwards with his tongue. If wife suddenly gets pregnant from this, she will bear another man's child and he must raise them. After years of such lifestyle the wife decided that he suffered enough and told him about that. He thought he'd finally get a release, but she wanted him to get his cock completely removed and become a real girl instead. Then without ever getting his last penile orgasm he got himself a real pussy through surgery and he lived as a woman taking cocks with his wife for the rest of his life
