This is absolutely my favorite sort of bully story, especially when it's combined with gaslighting the son. It's why Cuckoldson's classic story "Conflicted" is my favorite ever. The only way it could have been better was if Leslie (the mother) and Stuart (the bully) had been able to plant some possession of Lewis's (the son) at the scene of some vandalism committed by Stuart and gotten Lewis arrested and sent to jail. (I'd still like to see something like that in a story.)
Yes, I would have liked it a lot better had the story got into something similar. However, as of today, given the amount of hate andibob69 received over his story, I don't think other writers (atleast on Lit) would be interested in indulging into this stuff.
I have been searching through a lot of forums, unfortunately such stories appear to be a rare find. Honestly, I am a bit surprised this isn't a usual thing.
DM me in case you have any other stories (on any platform). Or better, please post it on this thread so that anyone else having similar kinks can also extend their gratitude!
