No. Any form of abuse in fanfiction, especially when it involves a 'baby bone' which might imply a child - like or vulnerable character in the Undertale universe, is not acceptable. It goes against basic moral and ethical values.
Well, it could be really interesting. Maybe it shows a unique interaction between Chara from Storyshift and Sans from Undertale. Their personalities are quite different. Chara can be rather complex and Sans is known for his laid - back yet perceptive nature. So in the fanfiction, there might be a lot of unexpected exchanges and development of their relationship.
One interesting Sans Undertale fanfic is 'Inverted Fate'. It offers a unique take on the Undertale universe, with well - developed characters and an engaging plot that keeps you hooked from start to finish. Another great one could be 'Swapfell Sans - The Cold - Hearted Protector' which delves into the character of Swapfell Sans in a really interesting way, showing his complex personality.
In 'Undertale Pregnant Sans' fanfiction, a frequently seen theme is the relationship dynamics. How Sans' relationships, whether it's with his friends or family (if applicable in the fanfiction's interpretation), are affected. There might also be themes related to the challenges he faces during the pregnancy, like dealing with potential threats in the Underground while being in a vulnerable state. Also, some fanfictions might explore the idea of Sans preparing for the new life that's coming, which could involve everything from gathering resources to making emotional preparations.
One great Sans x OC fanfiction is 'A New Beginning'. It focuses on an OC who enters the Undertale world and forms a unique bond with Sans. The story has interesting character development and a well - crafted plot that keeps you engaged.
First, develop your OC well. Give them a unique personality, backstory, and appearance. For example, if your OC is shy, explain why. Second, understand Sans' character from the original Undertale. His laid - back yet observant nature should be reflected in the interactions. Third, create an interesting plot. Maybe your OC has a special power that affects the Undertale world in a new way. Also, use good grammar and spelling to make it a pleasant read.
I'm sorry, but I don't have specific 'Undertale Pregnant Sans' fanfiction to recommend directly. You could try searching on popular fanfiction websites like Archive of Our Own (AO3) or Fanfiction.net. They usually have a large collection of Undertale - related fanfictions, and you might be able to find what you're looking for by using relevant keywords in their search bars.
One popular one might be 'A Tale of Two Skeletons'. It delves deep into the relationship between undertale sans and underswap papyrus, exploring their different personalities and how they interact in a unique AU setting.
Another plotline could be that there is a rift in the multiverse, and Chara and Sans are brought together to fix it. Along the way, they discover things about each other's universes and themselves, and in the end, they manage to close the rift and return to their respective worlds with a new understanding of the multiverse.
