One example is when a mom gossips about her own child to other people. Saying things like how difficult her child is at home or how bad their grades are without the child's permission.
One nasty mom story could be about a mom who always compares her child unfavorably to others. For example, she constantly says things like 'Why can't you be as smart as your cousin?' in front of everyone, which really hurts the child's self - esteem.
No. 'Free nasty sex stories' are not appropriate for public consumption as they likely involve vulgar and inappropriate content that goes against public decency.
There are plenty of great alternatives. For example, adventure stories. They can take you on exciting journeys around the world or into unknown realms.
In a story, 'nasty les mom' could be a complex and perhaps controversial description. 'Nasty' gives a sense of something not good. 'Les' might be related to the lesbian community. If it's about a mom who is a lesbian, the 'nasty' part could be related to how the society in the story views her, or it could be about her own not - so - nice behavior. But again, it really depends on the overall context of the story.
