There's no evidence to suggest that such a story is true. It might be a fictional or exaggerated account created for shock value or to gain attention. We should be cautious about believing such unusual stories without proper verification.

No, it is completely inappropriate. Teaching a little sister about sex stories is not only unethical but can also have a very negative impact on her mental and emotional development. Children at a young age are not ready to be exposed to such adult - related topics.
These kinds of topics are not suitable for public discussion. We should promote topics that are family - friendly, educational, and promote good values. For example, stories about kindness, friendship, or achievements in different fields.
If it were true, it would be a serious breach of ethical standards. Dolphins are sentient beings, and this kind of behavior would be a form of animal abuse.
Once upon a time, there was a little brother and a little sister. They lived in a small cottage by the woods. One day, they decided to go on an adventure in the forest. The little brother was brave and led the way, while the little sister was a bit scared but curious. As they walked deeper, they found a beautiful meadow filled with colorful flowers. They played there all day, making flower crowns for each other and chasing butterflies.
