I'm not sure what you specifically mean by 'gf cock competition'. It could be a very unusual or misphrased concept. If you mean a competition related to roosters (cock) and a girl (gf) perhaps in a rural farming context where there's a competition among roosters and a girl is involved in some way, like judging? But this is just speculation.
Suppose there's a group of friends, a girl and some guys. They often play games together. One day they start a 'cock - a - doodle - doo' competition. The 'gf' has to imitate the sound of a rooster better than the guys. She practices hard and comes up with a really creative and loud imitation. In the end, she wins the competition and they all have a great laugh about it.
If 'GF Cock' is a name in a particular story, we would need to know the details of the story such as the plot, the character's role, and the overall theme. Then we could start to compare it with other stories perhaps in terms of character development, like how the character grows or changes over time in the story compared to characters in other stories. Another aspect could be the setting, whether the environment in which 'GF Cock' exists in the story is similar to or different from other stories.
I'm sorry, but this topic involves inappropriate and vulgar content. We can focus on positive and family - friendly topics like 'Tell me a story about a couple's adventure.'
The term 'gf' is short for girlfriend. But the 'cheating massive cock story' is a rather offensive - sounding phrase. It might be part of some unwholesome or fictional tale where a girlfriend is involved in some form of unfaithful behavior that is being described in a vulgar manner. Since there's no additional context, it's difficult to give a more precise meaning.
I'm sorry, but this kind of description involves vulgar and inappropriate content. We can talk about positive and healthy topics such as relationship building, mutual respect in a relationship.
I have no idea what 'GF Cock' is in relation to a story. It's a rather strange term. Maybe it's a misnomer or something very specific within a certain group or context that I'm not aware of.
Discovering such a situation can be a shock. Calm down and talk to her privately. If she admits to something inappropriate, you have to consider your boundaries. Are you willing to overlook it if it was a one - time mistake? Or is it a deal - breaker for you? Also, think about how this will affect your trust in her in the future. If you can't trust her again, it might be best to part ways, but it's a very personal decision that depends on many factors like how long you've been together, how much you love her, etc.
