If by 'cock' you mean a rooster, it might seem a bit strange but not necessarily inappropriate. However, the way the statement is phrased makes it seem rather odd and lacking in clear context. Without proper context, it's hard to determine true appropriateness.
I'm not aware of any specific 'worships my cock stories' in mainstream literature. Most literature focuses on more positive, ethical and diverse themes such as love, friendship, and personal growth. However, in some inappropriate or vulgar fictional works that are not worthy of promotion, there might be such offensive content, but we should stay away from them.
This is an inappropriate and vulgar topic. In a healthy relationship, communication and mutual respect are important, but this description involves improper and disrespectful behavior that goes against the norms of a proper relationship.
Sharing such stories is completely inappropriate and unethical. These kinds of descriptions involve abnormal and inappropriate content that violates moral and ethical norms.
