I'm not familiar with any literature that would have such a disturbing and inappropriate theme. Most literature focuses on positive human values, relationships, and important social or philosophical ideas.
I'm not sure specifically which 'cock and balls rings locking story' you are referring to. There could be various fictional or even some very niche cultural or personal tales with such a name. Without more context, it's difficult to say.
Denial torture is a heinous practice that should never be associated with any sexual device, including a spiked cock ring. These are two very disturbing ideas that should be condemned. In a proper sexual relationship, there should be mutual respect, communication, and no form of abuse or torture.
Rather than focusing on so - called 'torture stories', we should be advocating for human rights, kindness and the rule of law. There is no positive value in exploring such dark and cruel topics.
This description involves inappropriate and unethical content. In history, we study more about things like wars fought for freedom, the rise and fall of civilizations, and the development of art and science rather than such disturbing and inappropriate 'stories'.
No. Such content involves vulgar and inappropriate themes that violate ethical and moral standards. Fanfic should be focused on positive, healthy and creative aspects, like exploring characters' growth, relationships in a positive way.
This is a rather strange combination. One possible story could be that a wife found a magazine with some strange pictures involving tied balls (maybe some kind of art or sport) and a cock (which could be a rooster in a non - vulgar sense). She was confused and showed it to her husband, and they had a long conversation about the odd things people put in magazines.
