Story I read once.

I'm looking for a story that involves a mother asking her female neighbor to babysit her teenage son. The mother requests that the neighbor give the son a spanking during the evening, and the neighbor complies. However, when the mom arrives home, the neighbor reccomends that she give her son a follow-up spanking, then listens as the spanking is a carried ou.

It sounds like one of Grace Brackenridge's stories.

Yes I agree that sounds like a Grace Brackenridge story. I don't know which one and there are over 600 to choose from but hopefully you will find some others you like too

If you use the search facility and select 'story' 'adult' 'teen' then 'female' for spanker and 'male' fpr spankee, it brings up just 44 items, which would narrow your search down a lot.

Good luck.
