Another option is 'The Story of Sister, Prince and the Denial of the Giant Bird'. By changing 'giant cock' to 'giant bird', we make it more appropriate for a general audience.
I'm sorry but this involves inappropriate and vulgar content, so I can't provide relevant stories.
Change the story to be about a game or a bet. Maybe the stepson lost a bet to the stepmom and his punishment is to do tasks related to her feet for a short period, like polishing her shoes. But during this time, they start to bond better and understand each other more as family members.
One way is to focus on the emotional aspects rather than the inappropriate ones. For example, if there's a situation where the husband feels threatened by another man's presence in his wife's life, we can emphasize the husband's insecurities and how he overcomes them through communication with his wife, leaving out any sexual implications.
We could simply change it to 'The Big Book of Ghost Stories'. By removing the 'erotic' part, it becomes more accessible to a wider range of readers, especially those who are interested in spooky tales without any adult themes.
It could be that the 'Sister' is a kind - hearted girl and the 'Prince' is a brave young man. The 'giant cock' is a guardian of a magical tree. 'Orgasm Denial' could be re - interpreted as the denial of some great power or magic that the tree holds. So the sister and prince have to figure out how to convince the giant cock to let them access the tree's power.
If we want to keep the idea of something large, we could use a 'giant tree'. The story could be about how the giant tree stands tall and provides shelter and beauty to the forest. We completely remove any idea of 'nudity' and create a story that is suitable for all ages.
Perhaps 'Stepdad's Tale of the Rooster'. This simple rewrite keeps it family - friendly and clearly indicates that it will be a story related to a stepdad and a rooster.
We could change it to something like 'Little sister drinks milk'. This is a simple and appropriate way that gets rid of the inappropriate implications in the original title.
We could rewrite it as 'Naruto Interrupts Tsunade's Moment of Intense Emotion'. This way, it still captures the essence of Naruto getting in the way of Tsunade's important moment without any inappropriate connotations.
We could rewrite it as 'She wanted his story'. This way, we remove the ambiguous and potentially inappropriate word 'cock' and just focus on the fact that she was interested in his story.
