If 'in too deep' is a movie, perhaps the real story could be about a character who gets involved in a dangerous situation, like a criminal underworld or a complex relationship. They might initially think they can handle it but then find themselves way over their heads, and the movie would show their journey to either get out or face the consequences.
I'm not sure specifically what this 'taking 1st big cock story' is. It could be a very specific or even a made - up story within a particular context that I'm not familiar with.
I'm not sure specifically which 'in too deep real story' you're referring to. There could be many stories with this title or concept. It might be about someone getting involved in a situation that they can't easily get out of, like a difficult relationship or a complex business deal.
Imagine a group of tourists visiting a rural area. They decided to take a walk outside. As they walked through a field, they came across a flock of cocks. There were dozens of them. The cocks were not afraid of the tourists and continued their activities. Some were fighting over food, others were preening their feathers. The tourists were amazed by this sight of so many cocks outside and one of them wrote a story about it later, which could be an 'outside taking lots of cock story'.
