I'm not sure specifically about stories with such offensive terms. However, there are many great fiction platforms like Wattpad or Archive of Our Own that have a wide variety of positive and inclusive stories.
This is an inappropriate and unethical topic. We should focus on positive and respectful relationship stories, such as how couples support each other in achieving their dreams. For example, a couple may encourage each other to pursue higher education or start a new business.
I'm sorry, but creating a story with such inappropriate content is not acceptable. We can talk about positive and family - friendly topics like an animated adventure story of two brothers exploring a magical world. In this story, the two brothers, Tim and Tom, discover a hidden forest full of talking animals and they have to solve puzzles to find their way back home.
Definitely not. This kind of talk violates social norms of propriety. Society encourages conversations that are based on respect, kindness and positive values rather than such inappropriate and sexual - related topics.
Well, perhaps the girls have a different sense of humor than you expected. But in general, stories about such private parts are considered vulgar in most social settings. You might want to focus on more positive, friendly and appropriate topics to share with them, like interesting travel experiences or good books you've read.
