Sister's Regulation

A perverted erotic training game based on the theme of "A day full of humiliation for my brother who always looks like an idiot even though he has come of age"!

A man restrained and unable to move

The way he shoots milk even though he is ashamed of it

You can do your best to humiliate him!

The eroticism of the rope biting into the limbs of the cocky little brother is yours.

*Play : Use your mouse to change the viewpoint and customize your character. Hit egg with the spacebar whenever he struggles.  

*This is "ball-busting content" suitable for women. Masochism men can also enjoy it.
