I'm sorry but I cannot promote or discuss adult fanfiction. Instead, there are fanfictions that depict Toriel's kind and wise nature in a positive light. They may show her interactions with other characters in the Undertale universe, like her cooking for them or sharing her wisdom about the Underground.
One popular 'Asgore x Toriel fanfiction' might be those that explore their past relationship and how they could potentially reconcile. For example, some stories might focus on the emotional journey they go through as they remember the good times before their separation.
Adult fanfiction is not appropriate content in general. However, if we were to consider fanfiction about Toriel in a non - adult context, there are many positive aspects. Her character is often depicted as a warm - hearted and motherly figure, and fanfictions can explore her relationships with other characters more deeply.
There are likely some out there, but I would caution against seeking out 'lemon' content which usually implies sexual or adult - themed stories. It's better to focus on positive, character - building fanfictions that explore the relationship between Sans and Toriel in a more innocent and friendly way. For example, stories that might show them working together to help the other characters in the Underground.
Here are some plot ideas. First, the adult human could be a scientist. They meet Toriel and start to analyze the magic in the Underground. As they collaborate, they grow closer. Second, the human might be a storyteller. They tell Toriel tales of great heroes and adventures from the surface. Toriel is so captivated that she wants to be part of those stories with the human. Third, the human has a troubled past. Toriel, with her motherly nature, helps the human heal. Through this process, their relationship blossoms. In all these ideas, their relationship can develop in a non - sexual, deep and meaningful way, exploring themes of friendship, understanding and hope.
There's 'Toriel's Guidance' in which Toriel imparts her wisdom to the reader. It's really interesting as it delves deep into her character while involving the reader in her world. The story has a very engaging plot that keeps you hooked from start to finish.
I'm not aware of specific 'frisk and toriel lemon fanfiction' stories as such content often involves inappropriate or non - canon interpretations. However, if you're interested in fanfiction about Frisk and Toriel in a more general and appropriate sense, there are many works that explore their relationship in a platonic or family - like way. For example, stories might focus on Toriel's motherly care for Frisk in the Underground.
A plot could be that Asgore discovers Toriel is pregnant and realizes he still has feelings for her. He then tries to be a part of her life again in a positive way. They could go through the journey of getting to know each other again, while also preparing for the baby. There could be scenes of them talking about their past mistakes and how they want to be better for the baby, creating a story full of redemption and new beginnings.
In Toriel fanfic, she is often depicted as extremely kind. For example, she might be shown taking in and caring for lost or injured creatures. She is also usually portrayed as very motherly, like in the official game. She may be written as having a strong sense of justice, not allowing any harm to come to the innocent.
One possible plot could be the human adult getting lost in the Underground and Toriel finding and taking care of them. As they spend time together, they learn about each other's cultures and values. Another plot could be that the human adult has a special ability that Toriel needs to protect the Underground, so they team up. And a third plot could be that the human adult is on a quest to find a way out of the Underground, and Toriel reluctantly helps them, but along the way, they form a strong bond.
One popular Toriel x Asgore fanfiction is 'Reconciliation'. It delves into their relationship after the events in the game, exploring how they might come to terms with their past and rekindle their connection. Another great one is 'The Royal Reunion' which shows their interactions in a more light - hearted and nostalgic way, as they remember the old days in the Underground.
