Literature generally focuses on positive values and themes. The term "pussy whipping" is inappropriate for literature, so there is no such well - known story.
Using that expression is not proper. Here is a story of a loving mother. A mother always cooked her child's favorite meals. When the child had to move away for college, she sent care packages full of home - cooked goodies regularly. She would also write long letters with words of encouragement and love, which made the child feel that her love was always there no matter how far away.
In a civilized society, we uphold values such as respect, family harmony and propriety. 'Cum in step mom stories' clearly violate these values and thus have no place in literature.
One story could be about a ygirl who was misbehaving by not doing her homework regularly. Her mom decided on a creative form of discipline. Instead of the usual scolding, she made the ygirl write an essay about the importance of education every time she missed homework. This 'whipping' in a sense was more of a mental nudge to get her on the right track.
Educate yourself about appropriate family values and boundaries. By understanding what is respectful and moral, you can easily recognize and avoid such inappropriate stories. Also, encourage those around you to uphold positive values.
