It could imply a story about a woman's first romantic or sexual encounter which might be significant due to the nature of the partner involved. However, without more context, it's hard to be certain.
In a literary sense, if we were to analyze it without focusing on the inappropriate nature of the phrase, 'his big dick' might symbolize his power or dominance in her story. Maybe it's about a male figure who has a large impact on the female protagonist's journey, but again, this is a rather unrefined way to put it.
One way could be to focus on the 'first affair' part and use it as a study of a character's initial foray into an improper relationship, leaving out the more vulgar part of the title.
It could imply a return to a story or narrative that involves Caucasian characters and themes related to sex. However, without more context, it's hard to be very specific.
It could imply a love story full of passion and sacrifice. The saliva might represent an intense closeness or perhaps a desperate kiss, while the blood - stained aspect could suggest pain, struggle or sacrifice within the relationship.
If we take it out of the sexual context, 'too big for a fleshlight' could imply that an object is too large for a particular container or holder. For example, a large tool might be too big for a small storage case.
It could be part of a fictional or exaggerated storytelling session among friends. Maybe they are sharing some made - up, comical tales related to the idea in a very private and girl - only conversation.
In a fictional context, 'a story a story' might be a signal that the story is a story within a story. Maybe it's a way for a character to pass on a special tale that has been passed down through generations. For example, in a fantasy world, an elder might say 'a story a story' before telling the young ones about the great heroes of the past. The heroes' deeds are then recounted in the following story, which is nested within this initial call to storytelling.
We could try to find more positive and appropriate synonyms to convey similar ideas. For example, we could use terms like 'confident man' or 'dominant male figure' which are much more acceptable in general communication.
It could be a story where the wife, out of curiosity perhaps, secretly observes a stranger who has some notable physical feature, in this case 'big dick'. Maybe she's at a public place like a beach or a park and she notices this stranger and starts to spy on his actions out of pure intrigue.
