his cock in my boypussy story

It's most likely a fictional story. Such a description is often used in exaggerated or fictional tales for shock value or comical effect.

There's no common or mainstream understanding of a'sissy boypussy rectal pacifier story'. It might be some sort of avant - garde or underground creation. Maybe it was created by a particular group with their own unique and rather unorthodox ideas. Without more context, it's hard to define it more precisely.

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

One possible theme could be exaggeration. The author might be using this extreme description to make a point about over - the - top or outlandish things in the 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.

If 'cock' is misused here and should be something else, it's very hard to make sense of. Maybe it was a typo and was supposed to be 'clock' or 'cook'. In that case, it could be about her seeing stories related to cooking or clocks.

I would say no. The term itself is so off - putting and hard to decipher in a positive light. It doesn't seem to conform to any common positive values or ideas. If it was part of some sort of creative work, it would likely be considered offensive or at least not in line with what society generally views as positive. There's no obvious positive meaning that jumps out from such a strange combination of words.

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.'

I'm sorry, but this description involves vulgar and inappropriate content, so I can't provide relevant answers.

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.
