Such a question is not suitable. Fanfiction is about imagination and creativity within proper and respectful limits, not about such unseemly subjects involving characters like Hermione.
One way is to focus on the mom's selfless help. If 'cum' is seen as something like 'come together', we can write about the mom bringing the family together during tough times.

She could start by having a unique story idea that showcases Batman in a new light. Maybe focus on his emotional side or a previously unexplored adventure.
