I'm not aware of many mainstream literary works that specifically focus on such stories. Most literature tends to avoid this kind of rather racy and inappropriate content. However, in some underground or niche erotica, there might be something similar, but this is not part of the general literary canon.
Once upon a time, at a beach party, there was a very confident and stylish female. She was wearing a bikini. As she was running around having fun with her friends, her bikini bottom got a bit of a wedgie when she quickly sat down on a beach chair. But instead of being embarrassed, she just laughed it off and adjusted it playfully, making everyone around her laugh too.
No, they are not appropriate. Such stories can involve elements that are not suitable for public discussion. We should promote stories that uphold good values, like friendship, kindness and achievement. Wedgie - related stories with a sexual connotation go against the norms of decency.
It's inappropriate because it objectifies women. Focusing on something like a wedgie in a'sexy' context reduces a woman to a physical object rather than a person with thoughts, feelings, and dignity.
I'm not really aware of any such stories in mainstream popular literature. Most literature focuses on more complex themes like love, adventure, or social issues rather than this rather specific and inappropriate topic.
There was once a story where at a summer camp, a prankster decided to give his friend a wedgie as a joke. But instead of getting angry, the friend turned it into a competition of who could endure the most uncomfortable wedgie. It was all in good fun and they ended up laughing about it for days afterwards.
