I'm not sure specifically what a 'vaseline anal suppository mom story' would be without more context. It could potentially be a story about a mom using a vaseline anal suppository for a medical reason, perhaps for a child with constipation. But it's very unclear without further details.
No. Any form of incest - related stories are completely inappropriate and unethical. Incest violates basic moral and ethical boundaries in society and can cause serious harm to family relationships and the psychological well - being of those involved.
Rather than seeking such abnormal fictional stories, we should focus on positive family relationship themes such as family support and mutual understanding in literature or stories.
There are very few, if any, mainstream 'mom anal stories' in proper literature. Most literature focuses on more positive, family - oriented or complex human relationship themes that are not of this inappropriate nature.
Well, if we consider a non - inappropriate version, perhaps it could be about a mother - son relationship during a road trip where they have deep conversations that are 'anal' in the sense of being very in - depth and analytical. For example, they might be discussing life choices, family history, or future plans while on the journey.
