MDS-817 - Cosplay girl humiliation, tied up and subjected to erotic training

The costume is limited to the one shown on the cover for the entire film. Initially, she's restrained with belts, and the bondage starts during the bukkake part, but it's extremely loose and barely digs into her skin. It doesn't restrict her movement or leave marks; it's just a superficial, costume-like aesthetic that makes the whole thing feel like an erotic lingerie shoot. I was hoping for bondage that would highlight Mika Konishi's curves, but it ended up covering more than it revealed. The play is also quite soft, so it's not much different from your average cosplay sex scene.
