Stories where the mother cucks her son or mom-son SPH

[bilash]

I've read this type of erotic manga / doujinshi before . But I've yet to find a good literotica which is of this type. I find it rare in literotica of mom-son-small-penis-humiliation or mom cucks son with bull / bully where son is voyeur.
I would love it if you could suggest such stories.

There's a series called BUSTY MOM AND THE BULLIES by rmdexter. See if it's close to what you're looking for.
