One common theme is power exchange. In BDSM erotica stories, there's often a clear dynamic of one partner being in a dominant role and the other in a submissive one. Another theme could be exploration of boundaries, both physical and emotional. For example, characters might test the limits of pain or pleasure within the consensual BDSM framework. And trust is also a prevalent theme. The submissive partner has to trust the dominant completely to engage in these activities, and this trust is often a central part of the story's development.
To write a bdsm erotica story in a consensual way, first and foremost, clearly define the boundaries of the characters involved. For example, they should openly discuss their limits, likes, and dislikes before any BDSM activities start in the story. Communication is key. Use dialogue to show how the characters negotiate what they are comfortable with. Also, ensure that any pain or discomfort inflicted is within the agreed - upon limits and is for the purpose of pleasure or exploration, not harm.
Some books explore lesbian relationships in a historical context. For example, they might tell the story of how lesbians lived and loved during a particular era, facing different challenges and finding their own ways to be happy together without any inappropriate elements.
Power dynamics is a very common theme. There's usually a dominant and a submissive character, and the exploration of how power is exchanged between them. For example, in "Fifty Shades of Grey", Christian Grey is the dominant and Anastasia Steele is the submissive.
"Mercy Thompson" series by Patricia Briggs also has some undertones of bdsm in the relationships between the characters. The series mainly focuses on the urban fantasy aspect but there are elements of power exchange and dominance - submission in the relationships which are characteristic of bdsm, and at the same time, there is a strong romantic element.
One common theme could be power dynamics. In bdsm - themed stories, there's often an exploration of who has power and how it's negotiated between characters.
You could use words that evoke passion and sensuality like 'Forbidden Desire', 'Scandalous Seduction' or 'Tempting Tapestry'. These names give a hint of the passionate content in the story without being too explicit.
I'm not sure what exactly a'moo erotica story' is. 'Moo' is often associated with the sound a cow makes, and 'erotica' refers to sexually suggestive or arousing content. But this combination seems rather strange and might be a very specific or made - up concept that I'm not familiar with.
