Story Find Request: "Helping Mom Relax"

Story by rentahero

I remember reading a good story years ago called something like "Helping Mom Relax" or "Helping Mama Relax" or something along those lines.

It was a fairly simply story told from a daughter's perspective about what it was like to grow up with a futa mom. It wasn't a futa world, her mom was a mutant from a family of rednecks who all had mutations from inbreeding. There are two scenes I remember

1. the mom teaching her son how to masturbate by mutually masturbating with him in the bathroom

2. the daughter at the end finally giving her virginity to her mother, who was also losing her cock virginity at the same time
