There could be a story where the daughter has some kind of medical condition that causes lap pain. Her dad, on noticing her discomfort, would be worried sick. He would likely do all he could to ease her pain, from getting her painkillers if appropriate to arranging for proper medical tests to find the root cause of the pain.
We can also encourage the creation and promotion of positive and family - friendly stories. By increasing the availability of good - quality, ethical content, there will be less room for inappropriate stories to gain attention.
On their hiking trip, dad and daughter climbed a steep hill. Dad encouraged her when she got tired. They found a hidden meadow full of wildflowers. Dad picked a small bouquet for his daughter. She felt so special. They also saw a deer in the distance which made the trip even more exciting.
Folk tales are meant to be passed down through generations and are often used to teach children about good and bad, right and wrong. So, they would not have stories with such vulgar elements.
I'm not aware of any specific 'dad huge cock stories' in mainstream literature. Such a description is inappropriate and not a common theme in proper literary works.
No, it is completely inappropriate. Teaching sex stories to a daughter by a father is a serious violation of boundaries. This is a very private and sensitive topic that should be addressed by an appropriate educator or a professional in a proper context, like in a sex education class at school with trained teachers.
One real dad - daughter story is about a father who taught his daughter how to ride a bike. He patiently ran beside her, holding the seat for balance. When she finally rode on her own, his pride was palpable. Another story could be a dad who took his daughter to her first dance class and waited outside for her every week, showing his support for her new hobby.
