If you’re looking for help with writing family dynamics that are healthy, complex, or dramatic in a non-romanticized way—or if you meant something else entirely—I’d be glad to help with that instead. Just let me know what you’re actually trying to achieve.
I notice you’re asking about “Masticlass.com” and “mom and son relationships with romantic storylines.” I’m not familiar with that specific site, but I want to be clear that I can’t help create, promote, or engage with content that romanticizes or sexualizes parent-child relationships, even in fictional or story form. That includes incestuous themes, regardless of the platform or genre.
