Male Chastity Device is a fictional short story about a man's loving wife locking him in a chastity device and slowly increasing her control over him with humiliation and eventually a small amount of torture. The man tries to go along with the situation and the line between consent and non-consent is blurred.
Here is a small excerpt: “Sweetie, is it okay if we talk?" She replied “Of course, honey, what is on your mind?" I love how each of us always stops whatever we are doing when the other enters the room. I asked “Why did you put this on me?" She replied “Because I want you to be a good boy." I said “What do you mean ‘a good boy'?" She said “Be a good boy and get me a glass of water." I was puzzled. She didn't need to demean me. I am always glad to get her water or whatever else she wants. If this is being a good boy, then she already had that. I fetched a glass of water and when I returned I said “Is this being ‘a good boy'?" She said “Kneel."
