I was really hoping Marion to receive the mother of all spankings in the end, not just a single slap on the backside. Rather disappointing ending to say the least, but everything else is definitely a step up quality-wise from Grade-A Bully. The relationship is built up way better and the Chapter 2 spankings in particular shows a lot of promise.
Definitely would want to see more chubby butts getting swatted in the same vein, bonus points if they belong to snobbish older women like Marion.
