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.
If I were in such a situation, I would first try to find out the truth calmly. Maybe I'd look for evidence without jumping to conclusions right away. If it turned out to be true, I'd probably break up with her. Cheating is a serious betrayal of trust in a relationship.
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.'
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.
One way is to really get to know your partner well before getting into a serious relationship. Spend time with her friends and family to understand her values. And don't rush into things. Build a strong foundation of trust and respect gradually. In the 'cheating gf' situation, it seems like there were some underlying issues in the relationship that could have been avoided with better initial screening.
Once upon a time, there was a couple. The girlfriend started to secretly meet another man. The boyfriend, in a strange way, became a cuckold in this fantasy. One day, he found out when he saw her leaving a hotel with the other guy. He was heartbroken but also strangely fascinated by the situation, as if it was a nightmare come true.
Well, I once knew a guy. His girlfriend was always busy with work. One day, he met a new girl at a coffee shop. They started chatting a lot and he didn't tell his gf about it. Eventually, he found himself having feelings for this new girl. But when his gf noticed he was being distant, she confronted him. He realized his mistake and ended things with the new girl, begging his gf for forgiveness.
It can end with forgiveness. The boyfriend, despite the pain of being cheated on, decides to forgive his girlfriend and they work on rebuilding their relationship. This could involve a lot of communication and therapy - like sessions to address the issues that led to the cheating.
