MKMP-748 An ultimate gym that provides members with their ideal body by encouraging intense physical release through a large-butt-only course known as a humiliation-themed workout. Tenma Yui
The women-only short-term weight loss course turned out to be packed with embarrassing training!?
My big backside on display for everyone to see, drenched in sweat… it was so embarrassing I could hardly stand it.

As I started attending, I became captivated by the power of embarrassment… and slowly turned into a pervert.
