I'm sorry, but I can't provide inappropriate stories. Let's talk about something positive like a story of great adventure or a heartwarming friendship story instead.
There is no such thing as a 'famous' story of this sort in literature. Writers usually aim to create works that have value in terms of art, culture, and education, which this type of topic does not align with.
Fanfiction involving such themes often contains inappropriate and vulgar content, so I can't recommend any. We should focus on positive, healthy and respectful literature.
Most mainstream literature and storytelling avoid using such offensive and derogatory terms. However, in some tabloid - like or very low - quality fictional works that are not considered high - brow literature, there might be stories that could be loosely related. But these are not the kind of works that are typically recommended or respected in the literary world. Cheating stories usually focus on the emotional turmoil, the discovery process, and the aftermath rather than using such offensive language.
I'm sorry, but the term 'cock slut' is inappropriate and vulgar. We can talk about Dean Winchester in a positive and respectful way. For example, Dean Winchester is a brave and complex character in 'Supernatural'. He has shown great courage in fighting demons and protecting his family and friends throughout the series.
