An omorashi story often involves themes related to the urge to urinate. It could be about a character in a fictional situation who is desperate to find a bathroom or is in a situation where they can't relieve themselves immediately. For example, in some anime - inspired omorashi stories, a character might be on a long journey and there are no facilities around, creating a sense of tension and urgency.
In these types of manga, a mother's love can be presented in unconventional and sometimes disturbing forms. It might involve elements that are far from typical expressions of maternal affection, often for shock value or to explore taboo themes.
Yes, there are some manga that might be on the edge of being too suggestive but still have great stories. For example, 'Monster' by Naoki Urasawa. It has complex characters and a thrilling plot that keeps you engaged, without any hentai elements. It delves deep into the human psyche and moral dilemmas.
