Write a long and detailed story. Izuku Midoria is cucked by Ochako Uraraka and kept in permanent chastity. She flushed the key down the toilet and glued his lock shut, so that his clitty would stay locked, denied and frustrated for the rest of his life. He begged her not to do it, but she’s made up her mind already. She invites bulls to fuck them both and makes Izuku suck their big black cocks and swallow their cum, then take them up his boypussy and let them cum inside and fill him up. She loves it when a bull slaps his helpless caged clitty with his superior cock before entering his boypussy. She likes to play with his frustrated locked clitty and balls using her tongue and fingers, while bulls fuck her or him. Also she likes using his cage as a handle when she's getting fucked by bulls. He must clean all the cocks and Ochako’s pussy every time with his tongue, but for him no cleaning is allowed. The only way he is allowed to cum is from anal. He is constantly frustrated and hates his new life, but he can’t do anything about it.
