When his wife asks him to lock a chastity cage on his manhood for which she has the only key, he initially thinks it is simply for a little tease and denial play. However, he soon finds out she has way more in mind as she begins sleeping with an array of different bulls. For a long while the routine is consistent. He watches while different bulls have their way with her, until she meets a bull who is much different, choosing to feminize him and also make him participate, becoming just as submissive as his sexy wife.
