that's my cock sex story

Definitely not. Sharing something like that with a sister is highly unethical. Family relationships are based on respect, love, and appropriate boundaries. This kind of sharing violates those boundaries and can cause discomfort, harm to the relationship, and is not acceptable in a civilized family environment.

It could include how you first saw the rooster. For example, you might say 'I first saw the cock in a small farmyard. It was standing on a fence post, looking so majestic.'

No, it's not appropriate at all. This kind of content is not suitable for public discussion or sharing. It goes against basic respect for others and the values of a healthy society.

This involves inappropriate and unethical content, so I can't provide relevant stories.

Sharing such stories is completely inappropriate as it involves vulgar and inappropriate sexual content.

No, it's not okay. We should uphold a respectful and decent communication environment. Such content is not suitable for public or even private sharing as it goes against basic propriety and can make others uncomfortable.

No. Such a situation is highly unethical and goes against the principles of loyalty and respect in a relationship. It involves inappropriate and disrespectful behavior towards one's spouse and violates the boundaries of a committed relationship.

Well, if it's not about something inappropriate, perhaps it could be a story where your date showed extreme confidence, like a 'huge' personality trait that's being described in a rather bold way. For example, they might have been really assertive or had a large presence during the date.

We should focus on positive, healthy and respectful topics rather than such improper content.

This is extremely inappropriate behavior. Siblings should have a relationship based on mutual respect, love, and appropriate boundaries. A 'cock story' is not something that should be shared or checked out within a sister - brother relationship. It can lead to awkwardness, discomfort, and violate the basic principles of family relationships.
